1903







PREFACE


The earlier chapters of this collection are so much in the nature
of an autobiography that the author has long shrunk from the idea of
allowing them to see the light during his lifetime.  His repugnance
has been overcome by very warm expressions on the subject uttered
by valued friends to whom they were shown, and by a desire that
some at least who knew him in youth should be able to read what he
has written.

The author trusts that neither critic nor reader will object
because he has, in some cases, strayed outside the limits of his
purely personal experience, in order to give a more complete view
of a situation, or to bring out matters that might be of historic
interest.  If some of the chapters are scrappy, it is because he
has tried to collect those experiences which have afforded him most
food for thought, have been most influential in shaping his views,
or are recalled with most pleasure.

THE REMINISCENCES OF AN ASTRONOMER




I

THE WORLD OF COLD AND DARKNESS


I date my birth into the world of sweetness and light on one
frosty morning in January, 1857, when I took my seat between two
well-known mathematicians, before a blazing fire in the office
of the "Nautical Almanac" at Cambridge, Mass.  I had come on from
Washington, armed with letters from Professor Henry and Mr. Hilgard,
to seek a trial as an astronomical computer.  The men beside me
were Professor Joseph Winlock, the superintendent, and Mr. John
D. Runkle, the senior assistant in the office.  I talked of my
unsuccessful attempt to master the "Mécanique Céleste" of Laplace
without other preparation than that afforded by the most meagre
text-books of elementary mathematics of that period.  Runkle spoke
of the translator as "the Captain."  So familiar a designation of
the great Bowditch--LL. D. and a member of the Royal Societies of
London, Edinburgh, and Dublin--quite shocked me.

I was then in my twenty-second year, but it was the first time I
had ever seen any one who was familiar with the "Mécanique Céleste."
I looked with awe upon the assistants who filed in and out as upon men
who had all the mysteries of gravitation and the celestial motions at
their fingers' ends.  I should not have been surprised to learn that
even the Hibernian who fed the fire had imbibed so much of the spirit
of the place as to admire the genius of Laplace and Lagrange.  My own
rank was scarcely up to that of a tyro; but I was a few weeks later
employed on trial as computer at a salary of thirty dollars a month.

How could an incident so simple and an employment so humble be
in itself an epoch in one's life--an entrance into a new world?
To answer this question some account of my early life is necessary.
The interest now taken in questions of heredity and in the study of
the growing mind of the child may excuse a word about my ancestry
and early training.

Though born in Nova Scotia, I am of almost pure New England descent.
The first Simon Newcomb, from whom I am of the sixth generation, was
born in Massachusetts or Maine about 1666, and died at Lebanon, Conn.,
in 1745.  His descendants had a fancy for naming their eldest sons
after him, and but for the chance of my father being a younger son,
I should have been the sixth Simon in unbroken lineal descent. [1]

Among my paternal ancestors none, so far as I know, with the exception
of Elder Brewster, were what we should now call educated men.  Nor did
any other of them acquire great wealth, hold a high official position,
or do anything to make his name live in history.  On my mother's side
are found New England clergymen and an English nonconformist preacher,
named Prince, who is said to have studied at Oxford towards the end
of the seventeenth century, but did not take a degree.  I do not
know of any college graduate in the list.

Until I was four years old I lived in the house of my paternal
grandfather, about two miles from the pretty little village of
Wallace, at the mouth of the river of that name.  He was, I believe,
a stonecutter by trade and owner of a quarry which has since become
important; but tradition credits him with unusual learning and with
having at some time taught school.

My maternal grandfather was "Squire" Thomas Prince, a native of Maine,
who had moved to Moncton, N. B., early in his life, and lived there
the rest of his days.  He was an upright magistrate, a Puritan in
principle, and a pillar of the Baptist Church, highly respected
throughout the province.  He came from a long-lived family, and one
so prolific that it is said most of the Princes of New England are
descended from it.  I have heard a story of him which may illustrate
the freedom of the time in matters of legal proceedings before a
magistrate's court.  At that time a party in a suit could not be a
witness.  In the terse language of the common people, "no man could
swear money into his own pocket."  The plaintiff in the case advised
the magistrate in advance that he had no legal proof of the debt,
but that defendant freely acknowledged it in private conversation.

"Well," said the magistrate, "bring him in here and get him to talk
about it while I am absent."

The time came.

"If you had n't sued me I would have paid you," said the defendant.

On the moment the magistrate stepped from behind a door with the
remark,--

"I think you will pay him now, whether or no."

My father was the most rational and the most dispassionate of men.
The conduct of his life was guided by a philosophy based on Combe's
"Constitution of Man," and I used to feel that the law of the
land was a potent instrument in shaping his paternal affections.
His method of seeking a wife was so far unique that it may not be
devoid of interest, even at this date.  From careful study he had
learned that the age at which a man should marry was twenty-five.
A healthy and well-endowed offspring should be one of the main
objects in view in entering the marriage state, and this required
a mentally gifted wife.  She must be of different temperament from
his own and an economical housekeeper.  So when he found the age of
twenty-five approaching, he began to look about.  There was no one in
Wallace who satisfied the requirements.  He therefore set out afoot
to discover his ideal.  In those days and regions the professional
tramp and mendicant were unknown, and every farmhouse dispensed its
hospitality with an Arcadian simplicity little known in our times.
Wherever he stopped overnight he made a critical investigation of
the housekeeping, perhaps rising before the family for this purpose.
He searched in vain until his road carried him out of the province.
One young woman spoiled any possible chance she might have had by a
lack of economy in the making of bread.  She was asked what she did
with an unnecessarily large remnant of dough which she left sticking
to the sides of the pan.  She replied that she fed it to the horses.
Her case received no further consideration.

The search had extended nearly a hundred miles when, early one
evening, he reached what was then the small village of Moncton.
He was attracted by the strains of music from a church, went into
it, and found a religious meeting in progress.  His eye was at once
arrested by the face and head of a young woman playing on a melodeon,
who was leading the singing.  He sat in such a position that he could
carefully scan her face and movements.  As he continued this study
the conviction grew upon him that here was the object of his search.
That such should have occurred before there was any opportunity to
inspect the doughpan may lead the reader to conclusions of his own.
He inquired her name--Emily Prince.  He cultivated her acquaintance,
paid his addresses, and was accepted.  He was fond of astronomy, and
during the months of his engagement one of his favorite occupations
was to take her out of an evening and show her the constellations.
It is even said that, among the daydreams in which they indulged, one
was that their firstborn might be an astronomer.  Probably this was
only a passing fancy, as I heard nothing of it during my childhood.
The marriage was in all respects a happy one, so far as congeniality
of nature and mutual regard could go.  Although the wife died at the
early age of thirty-seven, the husband never ceased to cherish her
memory, and, so far as I am aware, never again thought of marrying.

My mother was the most profoundly and sincerely religious woman
with whom I was ever intimately acquainted, and my father always
entertained and expressed the highest admiration for her mental
gifts, to which he attributed whatever talents his children might
have possessed.  The unfitness of her environment to her constitution
is the saddest memory of my childhood.  More I do not trust myself
to say to the public, nor will the reader expect more of me.

My father followed, during most of his life, the precarious occupation
of a country school teacher.  It was then, as it still is in many
thinly settled parts of the country, an almost nomadic profession,
a teacher seldom remaining more than one or two years in the same
place.  Thus it happened that, during the first fifteen years of
my life, movings were frequent.  My father tried his fortune in a
number of places, both in Nova Scotia and Prince Edward Island.
Our lot was made harder by the fact that his ideas of education
did not coincide with those prevalent in the communities where
he taught.  He was a disciple and admirer of William Cobbett, and
though he did not run so far counter to the ideas of his patrons as
to teach Cobbett's grammar at school, he always recommended it to
me as the one by which alone I could learn to write good English.
The learning of anything, especially of arithmetic and grammar, by
the glib repetition of rules was a system that he held in contempt.
With the public, ability to recite the rules of such subjects as
those went farther than any actual demonstration of the power to
cipher correctly or write grammatically.

So far as the economic condition of society and the general mode of
living and thinking were concerned, I might claim to have lived in
the time of the American Revolution.  A railway was something read
or heard about with wonder; a steamer had never ploughed the waters
of Wallace Bay.  Nearly everything necessary for the daily life of
the people had to be made on the spot, and even at home.  The work
of the men and boys was "from sun to sun,"--I might almost say from
daylight to darkness,--as they tilled the ground, mended the fences,
or cut lumber, wood, and stone for export to more favored climes.
The spinning wheel and the loom were almost a necessary part of the
furniture of any well-ordered house; the exceptions were among people
rich enough to buy their own clothes, or so poor and miserable that
they had to wear the cast-off rags of their more fortunate neighbors.
The women and girls sheared the sheep, carded the wool, spun the
yarn, wove the homespun cloth, and made the clothes.  In the haying
season they amused themselves by joining in the raking of hay, in
which they had to be particularly active if rain was threatened;
but any man would have lost caste who allowed wife or daughter to
engage in heavy work outside the house.

The contrast between the social conditions and those which surround
even the poorest classes at the present day have had a profound
influence upon my views of economic subjects.  The conception which
the masses of the present time have of how their ancestors lived in
the early years of the century are so vague and shadowy as not to
influence their conduct at the present time.

What we now call school training, the pursuit of fixed studies
at stated hours under the constant guidance of a teacher, I could
scarcely be said to have enjoyed.  For the most part, when I attended
my father's school at all, I came and went with entire freedom,
and this for causes which, as we shall see, he had reasons for
deeming good.

It would seem that I was rather precocious.  I was taught the alphabet
by my aunts before I was four years old, and I was reading the Bible
in class and beginning geography when I was six.

One curious feature of my reading I do not remember to have seen
noticed in the case of children.  The printed words, for the most
part, brought no well-defined images to my mind; none at least that
were retained in their connection.  I remember one instance of this.
We were at Bedeque, Prince Edward Island.  During the absence of my
father, the school was kept for a time by Mr. Bacon.  The class in
reading had that chapter in the New Testament in which the treason
of Judas is described.  It was then examined on the subject.  To the
question what Judas did, no one could return an answer until it
came my turn.  I had a vague impression of some one hanging himself,
and so I said quite at random that he hanged himself.  It was with
a qualm of conscience that I went to the head of the class.

Arithmetic was commenced at the age of five, my father drawing me
to school day by day on a little sled during the winter.  Just what
progress I made at that time I do not recall.  Long years afterward,
my father, at my request, wrote me a letter describing my early
education, extracts from which I shall ask permission to reproduce,
instead of attempting to treat the matter myself.  The letter,
covering twelve closely written foolscap pages, was probably dashed
off at a sitting without supposing any eye but my own would ever
see it:--

    June 8th, '58.

 I will now proceed to write, according to your request,
 about your early life.

 While in your fifth year, your mother spoke several times
 of the propriety of teaching you the first rudiments of
 book-learning; but I insisted that you should not be taught
 the first letter until you became five. [2]  I think, though,
 that at about four, or four and a half I taught you to count,
 as far, perhaps, as 100.

 When a little over four and a half, one evening, as I came
 home from school, you ran to me, and asked, "Father, is not
 4 and 4 and 4 and 4, 16?"  "Yes, how did you find it out?"
 You showed me the counterpane which was napped.  The spot
 of four rows each way was the one you had counted up.
 After this, for a week or two, you spent a considerable
 number of hours every day, making calculations in addition
 and multiplication.  The rows of naps being crossed and
 complexed in various ways, your greatest delight was to
 clear them out, find how many small ones were equal to one
 large one, and such like.  After a space of two or three
 weeks we became afraid you would calculate yourself "out
 of your head," and laid away the counterpane.

 Winter came, and passed along, and your birthday came;
 on that day, having a light hand-sled prepared, I fixed
 you on it, and away we went a mile and a half to school.

 According to my belief in educational matters "that the
 slate should be put into the child's hands as soon as the
 book is," you of course had your slate, and commenced making
 figures and letters the first day.

 In all cases, after you had read and spelled a lesson, and
 made some figures, and worked a sum, suppose one hour's
 study, I sent you out, telling you to run about and play
 a "good spell."  To the best of my judgment you studied,
 during the five months that this school lasted, nearly four
 hours a day, two being at figures.

    * * * * *

 During the year that I taught at Bedeque, you studied
 about five hours a day in school; and I used to exercise
 you about an hour a day besides, either morning or evening.
 This would make six hours per day, nearly or quite two and
 a half hours of that time at numbers either at your slate
 or mentally.  When my school ended here, you were six and a
 half years of age, and pretty well through the arithmetic.
 You had studied, I think, all the rules preceding including
 the cube root. . . .

I had frequently heard, during my boyhood, of a supposed mental
breakdown about this period, and had asked my father for a description
of it in the letter from which I am quoting.  On this subject the
letter continues:--

 You had lost all relish for reading, study, play, or talk.
 Sat most of the day flat on the floor or hearth.  When sent
 of an errand, you would half the time forget what you went
 for.  I have seen you come back from Cale Schurman's crying,
 [3] and after asking you several times you would make out to
 answer, you had not been all the way over because you forgot
 what you went for.  You would frequently jump up from the
 corner, and ask some peculiar question.  I remember three
 you asked me.

 1st. Father, does form mean shape?  Yes.  Has everything
 some shape?  Yes.  Can it be possible for anything to be
 made that would not have any shape?  I answered no; and then
 showed you several things, explaining that they all had some
 shape or form.  You now brightened up like a lawyer who had
 led on a witness with easy questions to a certain point,
 and who had cautiously reserved a thunderbolt question, to
 floor the witness at a proper time; proceeded with, "Well,
 then, how could the world be without form when God made it?"

    * * * * *

 3d. Does Cale Schurman's big ram know that he has such big
 crooked horns on him?  Does he know it himself, I mean?
 Does he know himself that he has such horns on him?

 You were taken down suddenly I think about two or three days
 from the first symptoms until you were fairly in the corner.
 Your rise was also rapid, I think about a week (or perhaps
 two weeks) from your first at recovery, until you seemed
 to show nothing unusual.  From the time you were taken down
 until you commenced recovery was about a month.

 We returned to Prince Edward Island, and after a few weeks I
 began to examine you in figures, and found you had forgotten
 nearly all you had ever learned.

    * * * * *

 While at New London I got an old work on Astronomy; you
 were wonderfully taken with it, and read it with avidity.
 While here you read considerable in "Goldsmith's History
 of England."  We lived two years in New London; I think
 you attended school nearly one year there.  I usually asked
 you questions on the road going to school, in the morning,
 upon the history you had read, or something you had studied
 the day previous.  While there, you made a dozen or two of
 the folks raise a terrible laugh.  I one evening lectured
 on astronomy at home; the house was pretty well filled, I
 suppose about twenty were present.  You were not quite ten
 years old and small at that.  Almost as soon as I was done
 you said: "Father, I think you were wrong in one thing."
 Such a roar of laughter almost shook the house.

 You were an uncommon child for _truth_.  I never knew you
 to deviate from it in one single instance, either in infancy
 or youth.

 From your infancy you showed great physical courage in going
 along the woods or in places in the dark among cattle,
 and I am surprised at what you say about your fears of a
 stove-pipe and trees.

 Perhaps I should have said "mental" instead of physical
 courage, for in one respect you were uncommonly deficient
 in that sort of courage necessary to perform bodily labor.
 Until nine or ten years of age you made a most pitiful
 attempt at any sort of bodily or rather "handy" work.

    * * * * *

 An extraordinary peculiarity in you was never to leap past
 a word you could not make out.  I certainly never gave
 you any particular instructions about this, or the fact
 itself would not at the time have appeared so strange to me.
 I will name one case.  After a return to Wallace (you were
 eleven) I, one day, on going from home for an hour or so,
 gave you a borrowed newspaper, telling you there was a fine
 piece; to read it, and tell me its contents when I returned.
 On my return you were near the house chopping wood.  "Well,
 Simon, did you read the piece?"  "No, sir."  "Why not?"
 "I came to a word I did not know."  This word was just
 about four lines from the commencement.

 At thirteen you read Phrenology.  I now often impressed upon
 you the necessity of bodily labor; that you might attain
 a strong and healthy physical system, so as to be able to
 stand long hours of study when you came to manhood, for it
 was evident to me that you would not labor with the hands
 for a business.  On this account, as much as on account of
 poverty, I hired you out for a large portion of the three
 years that we lived at Clements.

 At fifteen you studied Euclid, and were enraptured with it.
 It is a little singular that all this time you never showed
 any self-esteem; or spoke of getting into employment at some
 future day, among the learned.  The pleasure of intellectual
 exercise in demonstrating or analyzing a geometrical problem,
 or solving an algebraic equation, seemed to be your only
 object.  No Junior, Seignour or Sophomore class, with annual
 honors, was ever, I suppose, presented to your mind.

 Your almost intuitive knowledge of geography, navigation,
 and nautical matters in general caused me to think most
 ardently of writing to the Admiral at Halifax, to know if
 he would give you a place among the midshipmen of the navy;
 but my hope of seeing you a leading lawyer, and finally
 a judge on the bench, together with the possibility that
 your mother would not consent, and the possibility that
 you would not wish to go, deterred me: although I think I
 commenced a letter.


Among the books which profoundly influenced my mode of life and
thought during the period embraced in the foregoing extracts were
Fowler's "Phrenology" and Combe's "Constitution of Man."  It may
appear strange to the reader if a system so completely exploded as
that of phrenology should have any value as a mental discipline.
Its real value consisted, not in what it taught about the position
of the "organs," but in presenting a study of human nature which,
if not scientific in form, was truly so in spirit.  I acquired the
habit of looking on the characters and capabilities of men as the
result of their organism.  A hot and impulsive temper was checked
by the reflection that it was beneath the dignity of human nature
to allow a rush of blood to the organs of "combativeness" and
"destructiveness" to upset one's mental equilibrium.

That I have gotten along in life almost without making (so far as I am
aware) a personal enemy may be attributed to this early discipline,
which led me into the habit of dealing with antagonism and personal
opposition as I would deal with any physical opposition--evade it,
avoid it, or overcome it.  It goes without saying, however, that no
discipline of this sort will avail to keep the passions of a youth
always in check, and my own were no exception.  When about fifteen I
once made a great scandal by taking out my knife in prayer meeting
and assaulting a young man who, while I was kneeling down during
the prayer, stood above me and squeezed my neck.  He escaped with a
couple of severe though not serious cuts in his hand.  He announced
his intention of thrashing me when we should meet again; so for
several days thereafter I tried, so far as possible, in going afield
to keep a pitchfork within reach, determined that if he tried the job
and I failed to kill him, it would be because I was unable to do so.
Fortunately for both of us he never made the attempt.

I read Combe's "Constitution of Man" when between ten and twelve
years of age.  Though based on the ideas of phrenology and not,
I believe, of high repute as a system of philosophy, it was as good
a moral tonic as I can imagine to be placed in the hands of a youth,
however fallacious may have been its general doctrines.  So far as I
can recall, it taught that all individual and social ills were due
to men's disregard of the laws of Nature, which were classified as
physical and moral.  Obey the laws of health and we and our posterity
will all reach the age of one hundred years.  Obey the moral law and
social evils will disappear.  Its reading was accompanied by some
qualms of conscience, arising from the non-accordance of many of its
tenets with those of the "Catechism" and the "New England Primer."
The combination of the two, however, led to the optimistic feeling
that all wrongs would be righted, every act of injustice punished,
and truth and righteousness eventually triumph through the regular
processes of Nature and Society.  I have been led to abandon this
doctrine only by much experience, some of which will be found in
the following pages.

In the direction of mathematical and physical science and reading
generally, I may add something to what I have quoted from my
father.  My grandfather Simon had a small collection of books in
the family.  Among those purely literary were several volumes of "The
Spectator" and "Roderick Random."  Of the former I read a good deal.
The latter was a story which a boy who had scarcely read any other
would naturally follow with interest.  Two circumstances connected
with the reading, one negative and the other positive, I recall.
Looking into the book after attaining years of maturity, I found it
to contain many incidents of a character that would not be admitted
into a modern work.  Yet I read it through without ever noticing
or retaining any impression of the indelicate side of the story.
The other impression was a feeling of horror that a man fighting a
duel and finding himself, as he supposed, mortally wounded by his
opponent, should occupy his mind with avenging his own death instead
of making his peace with Heaven.

Three mathematical books were in the collection, Hammond's Algebra,
Simpson's Euclid, and Moore's Navigator, the latter the predecessor
of Bowditch.  The first was a miserable book, and I think its methods,
which were crude in the extreme, though not incorrect, were rather
more harmful than beneficial.  The queer diagrams in Euclid had in
my early years so little attraction for me that my curiosity never
led me to examine its text.  I at length did so in consequence of a
passage in the algebra which referred to the 47th proposition of the
First Book.  It occurred to me to look into the book and see what
this was.  It was the first conception of mathematical proof that
I had ever met with.  I saw that the demonstration referred to a
previous proposition, went back to that, and so on to the beginning.
A new world of thought seemed to be opened.  That principles so
profound should be reached by methods so simple was astonishing.
I was so enraptured that I explained to my brother Thomas while
walking out of doors one day how the Pythagorean proposition, as it
is now called, could be proved from first principles, drawing the
necessary diagrams with a pencil on a piece of wood.  I thought that
even cattle might understand geometry could they only be communicated
with and made to pay attention to it.

Some one at school had a copy of Mrs. Marcet's "Conversations on
Natural Philosophy."  With this book I was equally enraptured.
Meagre and even erroneous though it was, it presented in a pleasing
manner the first principles of physical science.  I used to steal into
the schoolhouse after hours to read a copy of the book, which belonged
to one of the scholars, and literally devoured it in a few evenings.

My first undertaking in the way of scientific experiment was in
the field of economics and psychology.  When about fourteen I spent
the winter in the house of an old farmer named Jefferson.  He and
his wife were a very kindly couple and took much interest in me.
He was fond of his pipe, as most old farmers are.  I questioned
whether anything else would not do just as well as tobacco to smoke,
and whether he was not wasting his money by buying that article
when a cheap substitute could be found.  So one day I took his pipe,
removed the remains of the tobacco ashes, and stuffed the pipe with
tea leaves that had been steeped, and which in color and general
appearance looked much like tobacco.  I took care to be around when
he should again smoke.  He lit the pipe as usual and smoked it with,
seemingly, as much satisfaction as ever, only essaying the remark,
"This tobacco tastes like tea."  My conscience pricked me, but I
could say nothing.

My father bought a copy of Lardner's "Popular Lectures on Science
and Art."  In this I first read of electricity.  I recall an incident
growing out of it.  In Lardner's description of a Leyden jar, water
is the only internal conductor.  The wonders of the newly invented
telegraph were then explained to the people in out of the way places
by traveling lecturers.  One of these came to Clements, where we then
lived, with a lot of apparatus, amongst which was what I recognized
as a Leyden jar.  It was coated with tin-foil on the outside, but I
did not see the inner coating, or anything which could serve as the
necessary conductor.  So with great diffidence I asked the lecturer
while he was arranging his things, if he was not going to put water
into the jar.

"No, my lad," was his reply, "I put lightning into it."

I wondered how the "lightning" was going to be conveyed to the
interior surface of the glass without any conductor, such as water,
but was too much abashed to ask the question.

Moore's "Navigator" taught not only a very crude sort of trigonometry,
but a good deal about the warship of his time.  To a boy living on
the seacoast, who naturally thought a ship of war one of the greatest
works of man, the book was of much interest.

Notwithstanding the intellectual pleasure which I have described,
my boyhood was on the whole one of sadness.  Occasionally my
love of books brought a word of commendation from some visitor,
perhaps a Methodist minister, who patted me on the head with a word
of praise.  Otherwise it caused only exclamations of wonder which
were distasteful.

"You would n't believe what larnin' that boy has got.  He has more
larnin' than all the people around here put together," I heard
one farmer say to another, looking at me, in my own view of the
case, as if I were some monster misshapen in the womb.  Instead of
feeling that my bookish taste was something to be valued, I looked
upon myself as a _lusus naturæ_ whom Nature had cruelly formed to
suffer from an abnormal constitution, and lamented that somehow I
never could be like other boys.

The maladroitness described by my father, of which I was fully
conscious, added to the feeling of my unfitness for the world around
me.  The skill required on a farm was above my reach, where efficiency
in driving oxen was one of the most valued of accomplishments.
I keenly felt my inability to acquire even respectable mediocrity in
this branch of the agricultural profession.  It was mortifying to
watch the dexterous motions of the whip and listen to the torrent
of imperatives with which a young farmer would set a team of these
stolid animals in motion after they had failed to respond to my
gentle requests, though conveyed in the best of ox language.

I had indeed gradually formed, from reading, a vague conception
of a different kind of world,--a world of light,--where dwelt men
who wrote books and people who knew the men who wrote books,--where
lived boys who went to college and devoted themselves to learning,
instead of driving oxen.  I longed much to get into this world, but
no possibility of doing so presented itself.  I had no idea that it
would be imbued with sympathy for a boy outside of it who wanted to
learn.  True, I had once read in some story, perhaps fictitious, how
a nobleman had found a boy reading Newton's "Principia," and not only
expressed his pleased surprise at the performance, but actually got
the boy educated.  But there was no nobleman in sight of the backwoods
of Nova Scotia.  I read in the autobiography of Franklin how he had
made his way in life.  But he was surrounded with opportunities from
which I was cut off.  It does seem a little singular that, well known
as my tastes were to those around me, we never met a soul to say,
"That boy ought to be educated."  So far as I know, my father's
idea of making me a lawyer met with nothing but ridicule from the
neighbors.  Did not a lawyer have to know Latin and have money to
pursue his studies?  In my own daydreams I was a farmer driving his
own team; in my mother's a preacher, though she had regretfully to
admit that I might never be good enough for this profession.

[1] The actual sixth was my late excellent and esteemed cousin,
Judge Simon Bolivar Newcomb, of New Mexico.

[2] He had evidently forgotten the home instruction from my aunts,
received more than a year previous to the date he mentions.

[3] The grandfather of President Schurman of Cornell University.
I retain a dreamy impression of two half-grown or nearly grown boys,
perhaps between fourteen and eighteen years of age, one of whom
became, I believe, the father of the president.




II

DOCTOR FOSHAY


In the summer of 1851, when I had passed the age of sixteen, we
lived in a little school district a mile or two from the town of
Yarmouth, N. S.  Late in the summer we had a visit from a maternal
uncle and aunt.  As I had not seen Moncton since I was six years old,
and as I wanted very much to visit my grandfather Prince once more,
it was arranged that I should accompany them on their return home.
An additional reason for this was that my mother's health had quite
failed; there was no prospect of my doing anything where I was, and it
was hoped that something might turn up at Moncton.  There was but one
difficulty; the visitors had driven to St. John in their own little
carriage, which would hold only two people; so they could not take
me back.  I must therefore find my own way from St. John to Moncton.

We crossed the Bay of Fundy in a little sailing vessel.  Among the
passengers was an English ship captain who had just been wrecked
off the coast of Newfoundland, and had the saved remnant of his crew
with him.  On the morning of our departure the weather was stormy,
so that our vessel did not put to sea--a precaution for which the
captain passenger expressed great contempt.  He did not understand
how a vessel should delay going to see on account of a little storm.

The walk of one hundred miles from St. John to Moncton was for me,
at that time, a much less formidable undertaking than it would appear
in our times and latitude.  A thirty-mile tramp was a bagatelle,
and houses of entertainment--farmhouses where a traveler could rest
or eat for a few pennies--were scattered along the road.  But there
was one great difficulty at the start.  My instructions had been to
follow the telegraph wires.  I soon found that the line of telegraph
came into the town from one direction, passed through it, and then
left, not in the opposite direction, but perhaps at right angles
to it.  In which direction was the line to be followed?  It was
difficult to make known what I wanted.  "Why, my boy, you can't
walk to Moncton," was one answer.  In a shop the clerks thought I
wanted to ride on the telegraph, and, with much chuckling, directed
me to the telegraph office where the man in charge would send me on.
I tried in one direction which I thought could not be right, then
I started off in the opposite one; but it soon became evident that
that branch led up the river to Frederickton.  So I had to retrace
my steps and take the original line, which proved to be the right one.

The very first night I found that my grandfather's name was one to
conjure with.  I passed it with a hearty old farmer who, on learning
who I was, entertained me with tales of Mr. Prince.  The quality
which most impressed the host was his enormous physical strength.
He was rather below the usual stature and, as I remember him, very
slightly built.  Yet he could shoulder a barrel of flour and lift
a hogshead of molasses on its end, feats of strength which only the
most powerful men in the region were equal to.

On reaching my destination, I was not many days in learning that my
grandfather was a believer in the maxims of "Poor Richard's Almanac,"
and disapproved of the aimless way in which I had been bred.  He began
to suggest the desirableness of my learning to do something to make
a living.  I thought of certain mechanical tastes which had moved
me in former years to whittle and to make a reel on which to wind
yarn, and to mend things generally.  So I replied that I thought
the trade of a carpenter was the one I could most easily learn.
He approved of the idea, and expressed the intention of finding a
carpenter who would want my services; but before he did so, I was
started in a new and entirely different direction.

On her last visit to her birthplace, my mother brought back glowing
reports of a wonderful physician who lived near Moncton and effected
cures of the sick who had been given up by other doctors.  I need
hardly remark that physicians of wonderful proficiency--Diomeds of
the medical profession, before whose shafts all forms of disease
had to fall--were then very generally supposed to be realities.
The point which specially commended Dr. Foshay to us was that he
practiced the botanic system of medicine, which threw mineral and all
other poisons out of the materia medica and depended upon the healing
powers of plants alone.  People had seen so much of the evil effects
of calomel, this being the favorite alternative of the profession,
that they were quite ready to accept the new system.  Among the
remarkable cures which had given Dr. Foshay his great reputation was
one of a young man with dyspepsia.  He was reduced to a shadow, and
the regular doctors had given him up as incurable.  The new doctor
took him to his home.  The patient was addicted to two practices,
both of which had been condemned by his former medical advisers.
One was that of eating fat pork, which he would do at any hour of
the day or night.  The new doctor allowed him to eat all he wanted.
Another was getting up in the night and practicing an ablution of
the stomach by a method too heroic to be described in anything but
a medical treatise. [1]  He was now allowed to practice it to his
heart's content.  The outcome of the whole proceeding was that he
was well in a few months, and, when I saw him, was as lusty a youth
as one could desire to meet.

Before Mr. Prince could see a carpenter, he was taken ill.  I was
intensely interested to learn that his physician was the great doctor
I had heard of, who lived in the village of Salisbury, fifteen miles
on the road to St. John.

One of my aunts had an impression that the doctor wanted a pupil or
assistant of some kind, and suggested that a possible opening might
here be offered me.  She promised to present me to the doctor on
his next visit, after she had broached the subject to him.

The time for which I waited impatiently at length arrived.
Never before had I met so charming a man.  He was decidedly what we
should now call magnetic.  There was an intellectual flavor in his
talk which was quite new to me.  What fascinated me most of all was
his speaking of the difficulties he encountered in supplying himself
with sufficient "reading matter."  He said it as if mental food was
as much a necessity as his daily bread.  He was evidently a denizen
of that world of light which I had so long wished to see.  He said
that my aunt was quite right in her impression, and our interview
terminated in the following liberal proposition on his part:--

S. N. to live with the doctor, rendering him all the assistance in
his power in preparing medicines, attending to business, and doing
generally whatever might be required of him in the way of help.

The doctor, on his part, to supply S. N.'s bodily needs in food
and clothing, and teach him medical botany and the botanic system
of medicine.  The contract to terminate when the other party should
attain the age of twenty-one.

After mentioning the teaching clause, he corrected himself a moment,
and added: "At least all I know about it."

All he knows about it!  What more could heart desire or brain hold?

The brilliancy of the offer was dimmed by only a single consideration;
I had never felt the slightest taste for studying medicine or caring
for the sick.  That my attainments in the line could ever equal
those of my preceptor seemed a result too hopeless to expect.  But,
after all, something must be done, and this was better than being
a carpenter.

Before entering upon the new arrangement, a ratification was required
on both sides.  The doctor had to make the necessary household
arrangements, and secure the consent of his wife.  I had to ask the
approval of my father, which I did by letter.  Like General Grant
and many great men, he was a man of exceptional sagacity in matters
outside the range of his daily concerns.  He threw much cold water on
the scheme, but consented to my accepting the arrangement temporarily,
as there was nothing better to be done.

I awaited the doctor's next visit with glowing anticipation.  In due
course of time I stepped with him into his gig for the long drive,
expecting nothing less on the journey than a complete outline of the
botanic system of medicine and a programme of my future studies.
But scarcely had we started when a chilling process commenced.
The man erstwhile so effusive was silent, cold, impassive,--a marble
statue of his former self.  I scarcely got three sentences out of
him during the journey, and these were of the most commonplace kind.
Could it be the same man?

There was something almost frightful in being alongside a man who knew
so much.  When we reached our destination the horse had to be put away
in the stable.  I jumped up to the haymow to throw down the provender.
It was a very peculiar feeling to do so under the eye of a man who,
as he watched me, knew every muscle that I was setting in operation.

A new chill came on when we entered the house and I was presented
to its mistress.

"So you 're the boy that's come to work for the doctor, are you?"

"I have come to study with him, ma'am"' was my interior reply,
but I was too diffident to say it aloud.  Naturally the remark
made me very uncomfortable.  The doctor did not correct her,
and evidently must have told her something different from what
he told me.  Her tone was even more depressing than her words;
it breathed a coldness, not to say harshness, to which I had not
been accustomed in a woman.  There was nothing in her appearance
to lessen the unpleasant impression.  Small in stature, with florid
complexion, wide cheek bones that gave her face a triangular form,
she had the eye and look of a well-trained vixen.

As if fate were determined to see how rapid my downfall should be
before the close of the day, it continued to pursue me.  I was left
alone for a few minutes.  A child some four years old entered and
made a very critical inspection of my person.  The result was clearly
unfavorable, for she soon asked me to go away.  Finding me indisposed
to obey the order, she proceeded to the use of force and tried to
expel me with a few strong pushes.  When I had had enough of this,
I stepped aside as she was making a push.  She fell to the floor,
then picked herself up and ran off crying, "Mamma."  The latter soon
appeared with added ire infused into her countenance.

"What did you hit the child for?"

"I did n't hit her.  What should I want to strike a child like
that for?"

"But she says you hit her and knocked her down."

"I did n't, though--she was trying to push me and fell and hurt
herself."

A long piercing look of doubt and incredulity followed.

"Strange, very strange.  I never knew that child to tell a lie,
and she says you struck her."

It was a new experience--the first time I had ever known my word to
be questioned.

During the day one thought dominated all others: where are those
treasures of literature which, rich though they are, fail to satisfy
their owner's voracious intellectual appetite?  As houses were then
built, the living and sleeping rooms were all on one main floor.
Here they comprised a kitchen, dining room, medicine room, a little
parlor, and two small sleeping rooms, one for the doctor and one
for myself.  Before many hours I had managed to see the interior of
every one except the doctor's bedroom, and there was not a sign of a
book unless such common ones as a dictionary or a Bible.  What could
it all mean?

Next day the darkness was illuminated, at least temporarily,
by a ray of light.  The doctor had been absent most of the day
before on a visit to some distant patient.  Now he came to me
and told me he wanted to show me how to make bilious powders.
Several trays of dried herbs had been drying under the kitchen
stove until their leaves were quite brittle.  He took these and I
followed him to the narrow stairway, which we slowly ascended, he
going ahead.  As I mounted I looked for a solution of the difficulty.
Here upstairs must be where the doctor kept his books.  At each step
I peered eagerly ahead until my head was on a level with the floor.
Rafters and a window at the other end had successively come into
view and now the whole interior was visible.  Nothing was there but
a loft, at the further end of which was a bed for the housemaid.
The floor was strewn with dried plants.  Nothing else was visible.
The disillusion seemed complete.  My heart sank within me.

On one side of the stairway at a level with the floor was screwed a
large coffee mill.  The doctor spread a sheet of paper out on the
floor on the other side, and laid a line sieve upon it.  Then he
showed me how to grind the dry and brittle leaves in the coffee mill,
put them into the sieve, and sift them on the paper.  This work
had a scientific and professional look which infused a glimmer of
light into the Cimmerian darkness.  The bilious powders were made of
the leaves of four plants familiarly known as spearmint, sunflower,
smartweed, and yarrow.  In his practice a heaping teaspoonful of the
pulverized leaves was stirred in a cup of warm water and the grosser
parts were allowed to settle, while the patient took the finer parts
with the infusion.  This was one of Dr. Foshay's staple remedies.
Another was a pill of which the principal active ingredient was
aloes.  The art of making these pills seemed yet more scientific
than the other, and I was much pleased to find how soon I could
master it.  Beside these a number of minor remedies were kept in
the medicine room.  Among them were tinctures of lobelia, myrrh,
and capsicum.  There was also a pill box containing a substance
which, from its narcotic odor, I correctly inferred to be opium.
This drug being prohibited by the Botanic School I could not but
feel that Dr. Foshay's orthodoxy was painfully open to question.

Determined to fathom the mystery in which the doctor's plans for my
improvement were involved, I announced my readiness to commence the
study of the botanic system.  He disappeared in the direction of
his bedroom, and soon returned with--could my eyes believe it?--a
big book.  It was one which, at the time of its publication, some
thirty or forty years before, was well known to the profession,--Miner
and Tully on the "Fevers of the Connecticut Valley."  He explained
bringing me this book.

"Before beginning the regular study of the botanic system, you must
understand something of the old system.  You can do so by reading
this book."

A duller book I never read.  There was every sort of detail about
different forms of fever, which needed different treatment; yet
calomel and, I think, opium were its main prescriptions.  In due
time I got through it and reported to my preceptor.

"Well, what do you think of the book?"

"It praises calomel and opium too much.  But I infer from reading
it that there are so many kinds of fever and other diseases that
an immense amount of study will be required to distinguish and
treat them."

"Oh, you will find that all these minute distinctions are not
necessary when we treat the sick on the botanic system."

"What is the next thing for me?  Can I not now go on with the study
of the botanic system?"

"You are not quite ready for it yet.  You must first understand
something about phrenology.  One great difference between us and
doctors of the old school is that they take no account of difference
of temperament, but treat the lymphatic and bilious in the same way.
But we treat according to the temperament of the patient and must
therefore be expert in distinguishing temperaments."

"But I studied phrenology long ago and think I understand it quite
well."

He was evidently surprised at this statement, but after a little
consideration said it was very necessary to be expert in the subject,
and thought I had better learn it more thoroughly.  He returned to
his bedroom and brought a copy of Fowler's "Phrenology," the very
book so familiar to me.  I had to go over it again, and did so
very carefully, paying special attention to the study of the four
temperaments,--nervous, bilious, lymphatic, and sanguine.

Before many days I again reported progress.  The doctor seemed a
little impatient, but asked me some questions about the position
of the organs and other matters pertaining to the subject, which I
answered promptly and correctly by putting my fingers on them on
my own head.  But though satisfied with the answers, it was easy
to see that he was not satisfied with me.  He had, on one or two
previous occasions, intimated that I was not wise and prudent in
worldly matters.  Now he expressed himself more plainly.

"This world is all a humbug, and the biggest humbug is the best man.
That 's the Yankee doctrine, and that 's the reason the Yankees
get along so well.  You have no organ of secretiveness.  You have
a window in your breast that every one can look into and see what
you are thinking about.  You must shut that window up, like I do.
No one can tell from my talk or looks what I am thinking about."

It may seem incredible to the reader that I marveled much at
the hidden meaning of this allegorical speech, and never for one
moment supposed it to mean: "I, Dr. Foshay, with my botanic system
of medicine, am the biggest humbug in these parts, and if you are
going to succeed with me you must be another."  But I had already
recognized the truth of his last sentence.  Probably neither of us
had heard of Talleyrand, but from this time I saw that his hearty
laugh and lively talk were those of a manikin.

His demeanor toward me now became one of complete gravity, formality,
and silence.  He was always kindly, but never said an unnecessary
word, and avoided all reference to reading or study.  The mystery
which enveloped him became deeper month after month.  In his presence
I felt a certain awe which prevented my asking any questions as to
his intentions toward me.

It must, of course, be a matter of lifelong regret that two years
so important in one's education should have been passed in such a
way,--still, they were not wholly misspent.  From a teacher named
Monroe, [2] who then lived near Salisbury, I borrowed Draper's
Chemistry, little thinking that I would one day count the author among
my friends.  A book peddler going his rounds offered a collection of
miscellaneous books at auction.  I bought, among others, a Latin and a
Greek grammar, and assiduously commenced their study.  With the first
I was as successful as could be expected under the circumstances,
but failed with the Greek, owing to the unfamiliarity of the alphabet,
which seemed to be an obstacle to memory of the words and forms.

But perhaps the greatest event of my stay was the advent of a
botanic druggist of Boston, who passed through the region with a
large wagonload of medicines and some books.  He was a pleasant,
elderly gentleman, and seemed much interested on learning that
I was a student of the botanic system.  He had a botanic medical
college in or near Boston, and strongly urged me to go thither as
soon as I could get ready to complete my studies.  From him the
doctor, willing to do me a favor, bought some books, among them the
"Eclectic Medical Dispensary," published in Cincinnati.  Of this
book the doctor spoke approvingly, as founded on the true system
which he himself practiced, and though I never saw him read it,
he was very ready to accept the knowledge which I derived from it.
The result was quite an enlargement of his materia medica, both in the
direction of native plants and medicines purchased from his druggist.

On one occasion this advance came near having serious consequences.
I had compounded some pills containing a minute quantity of elaterium.
The doctor gave them to a neighboring youth affected with a slight
indisposition in which some such remedy was indicated.  The directions
were very explicit,--one pill every hour until the desired effect
was produced.

"Pshaw," said the patient's brother, "there's nothin' but weeds in
them pills, and a dozen of them won't hurt you."

The idea of taking weed pills one at a time seemed too ridiculous,
and so the whole number were swallowed at a dose.  The result was,
happily, not fatal, though impressive enough to greatly increase
the respect of the young man's family for our medicines.

The intellectual life was not wholly wanting in the village.  A lodge
of a temperance organization, having its headquarters in Maine,
was formed at a neighboring village.  It was modeled somewhat after
the fashion of the Sons of Temperance.  The presiding officer, with
a high sounding title, was my mother's cousin, Tommy Nixon.  He was
the most popular young man of the neighborhood.  The rudiments of a
classical education gained at a reputable academy in Sackville had not
detracted from his qualities as a healthy, rollicking young farmer.
The lodge had an imposing ritual of which I well remember one feature.
At stated intervals a password which admitted a member of any
one lodge to a meeting of any other was received from the central
authority--in Maine, I believe.  It was never to be pronounced except
to secure admission, and was communicated to the members by being
written on a piece of paper in letters so large that all could read.
After being held up to view for a few moments, the paper was held in
the flame of a candle with these words: "This paper containing our
secret password I commit to the devouring element in token that it no
longer exists save in the minds of the faithful brethren."  The fine
sonorous voice of the speaker and his manly front, seen in the lurid
light of the burning paper, made the whole scene very impressive.

There was also a society for the discussion of scientific questions,
of which the founder and leading spirit was a youth named Isaac
Steves, who was beginning the study of medicine.  The president
was a "Worthy Archon."  Our discussions strayed into the field
of physiological mysteries, and got us into such bad odor with
Mrs. Foshay and, perhaps, other ladies of the community, that the
meetings were abandoned.

A soil like that of the Provinces at this time was fertile in odd
characters including, possibly, here and there, a "heart pregnant
with celestial fire."  One case quite out of the common line was
that of two or three brothers employed in a sawmill somewhere up the
river Petticodiac.  According to common report they had invented a
new language in order to enable them to talk together without their
companions knowing what they were saying.  I knew one of them well
and, after some time, ventured to inquire about this supposed tongue.
He was quite ready to explain it.  The words were constructed out
of English by the very simple process of reversing the syllables or
the spelling.  Everything was pronounced backward.  Those who heard
it, and knew the key, had no difficulty in construing the words;
to those who did not, the words were quite foreign.

The family of the neighborhood in which I was most intimate was that
of a Scotch farmer named Parkin.  Father, mother, and children were
very attractive, both socially and intellectually, and in later years
I wondered whether any of them were still living.  Fifty years later
I had one of the greatest and most agreeable surprises of my life
in suddenly meeting the little boy of the family in the person of
Dr. George R. Parkin, the well-known promoter of imperial federation
in Australia and the agent in arranging for the Rhodes scholarships
at Oxford which are assigned to America.

My duties were of the most varied character.  I composed a little
couplet designating my professions as those of

    Physician, apothecary, chemist, and druggist,
    Girl about house and boy in the barn.

I cared for the horse, cut wood for the fire, searched field and
forest for medicinal herbs, ordered other medicines from a druggist
[3] in St. John, kept the doctor's accounts, made his pills, and
mixed his powders.  This left little time for reading and study,
and such exercises were still farther limited by the necessity of
pursuing them out of sight of the housewife.

As time passed on, the consciousness that I was wasting my growing
years increased.  I long cherished a vague hope that the doctor
could and would do something to promote my growth into a physician,
especially by taking me out to see his patients.  This was the
recognized method of commencing the study of medicine.  But he never
proposed such a course to me, and never told me how he expected me
to become a physician.  Every month showed my prospects in a less
hopeful light.  I had rushed into my position in blind confidence in
the man, and without any appreciation of the requirements of a medical
practitioner.  But these requirements now presented themselves to
my mind with constantly increasing force.  Foremost among them was
a knowledge of anatomy, and how could that be acquired except at a
medical school?  It was every day more evident that if I continued
in my position I should reach my majority without being trained for
any life but that of a quack.

While in this state of perplexity, an event happened which suggested
a way out.  One day the neighborhood was stirred by the news that
Tommy Nixon had run away--left his home without the consent of his
parents, and sailed for the gold fields of Australia.  I was struck
by the absence of any word of reprobation for his act.  The young men
at least seemed to admire the enterprising spirit he had displayed.
A few weeks after his departure a letter which he wrote from London,
detailing his adventures in the great metropolis, was read in my
presence to a circle of admiring friends with expressions of wonder
and surprise.  This little circumstance made it clear to me that
the easiest way out of my difficulty was to out the Gordian knot,
run away from Dr. Foshay, and join my father in New England.

No doubt the uppermost question in the mind of the reader will be:
Why did you wait so long without having a clear understanding with
the doctor?  Why not ask him to his face how he expected you to
remain with him when he had failed in his pledges, and demand that
he should either keep them or let you go?

One answer, perhaps the first, must be lack of moral courage to face
him with such a demand.  I have already spoken of the mystery which
seemed to enshroud his personality, and of the fascination which,
through it, he seemed to exercise over me.  But behind this was
the conviction that he could not do anything for me were he ever so
well disposed.  That he was himself uneducated in many essentials of
his profession had gradually become plain enough; but what he knew
or possibly might know remained a mystery.  I had heard occasional
allusions, perhaps from Mrs. Foshay rather than from himself, to an
institution supposed to be in Maine, where he had studied medicine,
but its name and exact location were never mentioned.  Altogether,
if I told him of my intention, it could not possibly do any good,
and he might be able to prevent my carrying it out, or in some other
way to do much harm.  And so I kept silent.

Tuesday, September 13, 1853, was the day on which I fixed for the
execution of my plan.  The day previous I was so abstracted as to
excite remarks both from Mrs. Foshay and her girl help, the latter
more than once declaring me crazy when I made some queer blunder.
The fact is I was oppressed by the feeling that the step about to
be taken was the most momentous of my life.  I packed a few books
and clothes, including some mementoes of my mother, and took the box
to the stage and post-office in the evening, to be forwarded to an
assumed name in St. John the next afternoon.  This box I never saw
again; it was probably stopped by Foshay before being dispatched.
My plan was to start early in the morning, walk as far as I could
during the day, and, in the evening, take the mail stage when it
should overtake me.  This course was necessitated by the fact that
the little money that I had in my pocket was insufficient to pay my
way to Boston, even when traveling in the cheapest way.

I thought it only right that the doctor should be made acquainted
with my proceeding and my reason for taking it, so I indited a short
letter, which I tried to reproduce from memory ten years later with
the following result:--

 Dear Doctor,--I write this to let you know of the step I am
 about to take.  When I came to live with you, it was agreed
 that you should make a physician of me.  This agreement you
 have never shown the slightest intention of fulfilling since
 the first month I was with you.  You have never taken me
 to see a patient, you have never given me any instruction
 or advice whatever.  Beside this, you must know that your
 wife treats me in a manner that is no longer bearable.

 I therefore consider the agreement annulled from your failure
 to fulfill your part of it, and I am going off to make my
 own way in the world.  When you read this, I shall be far
 away, and it is not likely that we shall ever meet again.

If my memory serves me right, the doctor was absent on a visit to
some distant patient on the night in question, and I did not think it
likely that he would return until at least noon on the following day.
By this time my box would have been safely off in the stage, and
I would be far out of reach.  To delay his receiving the letter as
much as possible, I did not leave it about the house, but put it in
the window of a shop across the way, which served the neighbors as
a little branch post-office.

But he must have returned sooner than I expected, for, to my great
regret, I never again saw or heard of the box, which contained,
not only the entire outfit for my journey, but all the books of my
childhood which I had, as well as the little mementoes of my mother.
The postmaster who took charge of the goods was a Mr. Pitman.
When I again passed through Salisbury, as I did ten years later,
he had moved away, no one could tell me exactly where.

I was on the road before daybreak, and walked till late at night,
occasionally stopping to bathe my feet in a brook, or to rest for
a few minutes in the shadow of a tree.  The possibility of my being
pursued by the doctor was ever present to my mind, and led me to keep
a sharp lookout for coming vehicles.  Toward sunset a horse and buggy
appeared, coming over a hill, and very soon the resemblance of vehicle
and driver to the turnout of the doctor became so striking that I
concealed myself in the shrubbery by the wayside until the sound of
the wheels told me he was well past.  The probability that my pursuer
was in front of me was an added source of discomfort which led me
to avoid the road and walk in the woods wherever the former was not
visible to some distance ahead.  But I neither saw nor heard anything
more of the supposed pursuer, though, from what I afterward learned,
there can be little doubt that it was actually Foshay himself.

The advent of darkness soon relieved me of the threatened danger,
but added new causes of solicitude.  The evening advanced, and the
lights in the windows of the houses were becoming fewer and fewer,
and yet the stage had not appeared.  I slackened my pace, and made
many stops, beginning to doubt whether I might not as well give up the
stage and look for an inn.  It was, I think, after ten o'clock when
the rattling of wheels announced its approach.  It was on a descending
grade, and passed me like a meteor, in the darkness, quite heedless
of my calls and gesticulations.  Fortunately a house was in sight
where I was hospitably entertained, and I was very soon sound asleep,
as became one who had walked fifty miles or more since daylight.

Thus ended a day to which I have always looked back as the most
memorable of my life.  I felt its importance at the time.  As I
walked and walked, the question in my mind was, what am I doing and
whither am I going?  Am I doing right or wrong?  Am I going forward
to success in life, or to failure and degradation?  Vainly, vainly,
I tried to peer into the thick darkness of the future.  No definite
idea of what success might mean could find a place in my mind.
I had sometimes indulged in daydreams, but these come not to a mind
occupied as mine on that day.  And if they had, and if fancy had
been allowed its wildest flight in portraying a future, it is safe
to say that the figure of an honorary academician of France, seated
in the chair of Newton and Franklin in the palace of the Institute,
would not have been found in the picture.

As years passed away I have formed the habit of looking back upon that
former self as upon another person, the remembrance of whose emotions
has been a solace in adversity and added zest to the enjoyment of
prosperity.  If depressed by trial, I think how light would this have
appeared to that boy had a sight of the future been opened up to him.
When, in the halls of learning, I have gone through the ceremonies
which made me a citizen of yet another commonwealth in the world of
letters, my thoughts have gone back to that day; and I have wished
that the inexorable law of Nature could then have been suspended,
if only for one moment, to show the scene that Providence held
in reserve.

Next morning I was on my way betimes, having still more than thirty
miles before me.  And the miles seemed much longer than they did the
day before, for my feet were sore and my limbs stiff.  Quite welcome,
therefore, was a lift offered by a young farmer, who, driving a
cart, overtook me early in the forenoon.  He was very sociable,
and we soon got into an interesting conversation.

I knew that Dr. Foshay hailed from somewhere in this region, where
his father still lived, so I asked my companion whether he knew a
family of that name.  He knew them quite well.

"Do you know anything of one of the sons who is a doctor?"

"Yes indeed; I know all about him, but he ain't no doctor.  He tried
to set up for one in Salisbury, but the people there must a' found
him out before this, and I don't know where he is now."

"But I thought he studied medicine in Fredericton or Maine or
somewhere on the border."

"Oh, he went off to the States and pretended to study, but he never
did it.  I tell you he ain't no more a doctor nor I am.  He ain't
smart enough to be a doctor."

I fell into a fit of musing long enough to hear, in my mind's
ear, with startling distinctness, the words of two years before:
"This world is all a humbug, and the biggest humbug is the best man.
. . . You have a window in your breast and you must close that window
before you can succeed in life."  Now I grasped their full meaning.

Ten years later I went through the province by rail on my wedding
journey.  At Dorchester, the next village beyond Moncton, I was
shown a place where insolvent debtors were kept "on the limits."

"By stopping there," said my informant, "you can see Dr. Foshay."

I suggested the question whether it was worth while to break our
journey for the sake of seeing him.  The reply of my informant
deterred me.

"It can hardly be worth while to do so.  He will be a painful object
to see,--a bloated sot, drinking himself to death as fast as he can."

The next I heard of him was that he had succeeded.

I reached St. John on the evening that a great celebration of the
commencement of work on the first railway in the province was in
progress.  When things are undecided, small matters turn the scale.
The choice of my day for starting out on my adventurous journey was
partly fixed by the desire to reach St. John and see something of
the celebration.  Darkness came on when I was yet a mile or two from
the city; then the first rocket I had ever beheld rose before me in
the sky.  Two of what seemed like unfortunate incidents at the time
were most fortunate.  Subsequent and disappointing experience showed
that had I succeeded in getting the ride I wished in the stage,
the resulting depletion of my purse would have been almost fatal
to my reaching my journey's end.  Arriving at the city, I naturally
found all the hotels filled.  At length a kindly landlady said that,
although she had no bed to give me, I was quite welcome to lie on a
soft carpeted floor, in the midst of people who could not find any
other sleeping place.  No charge was made for this accommodation.
My hope of finding something to do which would enable me to earn
a little money in St. John over and above the cost of a bed and a
daily loaf of bread was disappointed.  The efforts of the next week
are so painful to recall that I will not harrow the feelings of the
reader by describing them.  Suffice it to say that the adventure was
wound up by an interview at Calais, a town on the Maine border, a
few miles from Eastport, with the captain of a small sailing vessel,
hardly more than a boat.  He was bound for Salem.  I asked him the
price of a passage.

"How much money have you?" he replied.

I told him; whether it was one or two dollars I do not recall.

"I will take you for that if you will help us on the voyage."

The offer was gladly accepted.  The little craft was about as near the
opposite of a clipper ship as one can imagine, never intended to run
in any but fair winds, and even with that her progress was very slow.
There was a constant succession of west winds, and the result was that
we were about three weeks reaching Salem.  Here I met my father, who,
after the death of my mother, had come to seek his fortune in the
"States."  He had reached the conclusion, on what grounds I do not
know, that the eastern part of Maryland was a most desirable region,
both in the character of its people and in the advantages which it
offered us.  The result was that, at the beginning of 1854, I found
myself teacher of a country school at a place called Massey's Cross
Roads in Kent County.  After teaching here one year, I got a somewhat
better school at the pleasant little village of Sudlersville, a few
miles away.

Of my abilities as a manager and teacher of youth the reader can
judge.  Suffice it to say that, looking back at those two years, I
am deeply impressed with the good nature of the people in tolerating
me at all.

My most pleasant recollection is that of two of my best pupils of
Sudlersville, nearly my own age.  One was Arthur E. Sudler, for
whose special benefit some chemical apparatus was obtained from
Philadelphia.  He afterwards studied medicine at the University of
Pennsylvania and delighted me by writing that what I had taught him
placed him among the best in his class in chemistry.  The other was
B. S. Elliott, who afterward became an engineer or surveyor.

One of my most vivid recollections at Massey's relates to a subject
which by no means forms a part of one's intellectual development,
and yet is at the bottom of all human progress, that of digestion.
The staple food of the inhabitants of a Southern farming region was
much heartier than any to which I had been accustomed.  "Pork and
pone" were the staples, the latter being a rather coarse cake with
little or no seasoning, baked from cornmeal.  This was varied
by a compound called "shortcake," a mixture of flour and lard,
rapidly baked in a pan, and eaten hot.  Though not distasteful,
I thought it as villainous a compound as a civilized man would put
into his stomach.

Quite near my school lived a young bachelor farmer who might be
designated as William Bowler, Esq., though he was better known as
Billy Bowler.  He had been educated partly at Delaware College,
Newark, and was therefore an interesting young man to know.
In describing his experiences at the college, he once informed me
that they were all very pleasant except in a single point; that was
the miserably poor food that the students got to eat.  He could not,
he declared, get along without good eating.  This naturally suggested
that my friend was something of a gourmand.  Great, therefore,
was my delight when, a few weeks later, he expressed a desire to
have me board with him.  I accepted the offer as soon as possible.
Much to my disappointment, shortcake was on the table at the first
meal and again at the second.  It proved to be the principal dish
twice, and I am not sure but three times a day.  The other staple
was fried meat.  On the whole this was worse than pork and pone,
which, if not toothsome, was at least wholesome.  As the days grew
into weeks, I wondered what Delaware College could give its students
to eat.  To increase the perplexity, there were plenty of chickens
in the yard and vegetables in the garden.  I asked the cook if she
could not boil some vegetables and bring them on the table.

"Mas'er Bowler don't like wegetable."

Then I found that the chickens were being consumed in the kitchen
and asked for one.

"Mas'er Bowler don't like chicken," was the reply, with an added
intimation that the chickens belonged to the denizens of the kitchen.

The mystery was now so dark and deep that I determined to fathom it.
I drew Mr. Bowler into conversation once more about Delaware College,
and asked him what the students had to eat when there.

He had evidently forgotten his former remark and described what
seemed to me a fairly well provided students' table.  Now I came
down on him with my crusher.

"You told me once that the table was miserably poor, so that you
could hardly stand it.  What fault had you to find with it?"

He reflected a moment, apparently recalling his impression, then
replied: "Oh, they had no shortcake there!"

In 1854 I availed myself of my summer vacation to pay my first
visit to the national capital, little dreaming that it would ever be
my home.  I went as far as the gate of the observatory, and looked
wistfully in, but feared to enter, as I did not know what the rules
might be regarding visitors.  I speculated upon the possible object
of a queer red sandstone building, which seemed so different from
anything else, and heard for the first time of the Smithsonian
Institution.

On the very beginning of my work at Massey's the improvement in my
position was so remarkable that I felt my rash step of a few months
before fully justified.  I wrote in triumph to my favorite aunt,
Rebecca Prince, that leaving Dr. Foshay was the best thing I had
ever done.  I was no longer "that boy," but a respectable young man
with a handle to my name.

Just what object I should pursue in life was still doubtful; the
avenues of the preferment I would have liked seemed to be closed
through my not being a college graduate.  I had no one to advise me as
to the subjects I should pursue or the books I should study.  On such
books as I could get, I passed every spare hour.  My father sent me
Cobbett's English Grammar, which I found amusing and interesting,
especially the criticisms upon the grammar found here and there in
royal addresses to Parliament and other state papers.  On the whole
I am not sure but that the book justified my father's good opinion,
although I cannot but think that it was rather hypercritical.  I had
been taught the rudiments of French in Wallace when quite a child by
a Mr. Oldright, of whose methods and pronunciation my memory gives
me a most favorable impression.  I now got Cobbett's French Grammar,
probably a much less commendable book than his English one.  I had
never yet fathomed the mysteries of analytic geometry or the calculus,
and so got Davies' books on those subjects.  That on the calculus
was perhaps the worst that could be put into the hands of a person
situated as I was.  Two volumes of Bezout's Mathematics, in French,
about a century old, were, I think, rather better.  Say's Political
Economy was the first book I read on that subject, and it was quite
a delight to see human affairs treated by scientific methods.

I finally reached the conclusion that mathematics was the study I
was best fitted to follow, though I did not clearly see in what way I
should turn the subject to account.  I knew that Newton's "Principia"
was a celebrated book, so I got a copy of the English translation.
The path through it was rather thorny, but I at least caught the
spirit here and there.  No teacher at the present time would think
of using it as a text-book, yet as a mental discipline, and for
the purpose of enabling one to form a mental image of the subject,
its methods at least are excellent.  I got a copy of the "American
Journal of Science," hoping it might enlighten me, but was frightened
by its big words, and found nothing that I could understand.

During the year at Sudlersville I made several efforts which,
though they were insignificant so far as immediate results were
concerned, were in some respects of importance for my future work.
With no knowledge of algebra except what was derived from the meagre
text-books I could pick up,--not having heard even the name of
Abel, or knowing what view of the subject was taken by professional
mathematicians,--I made my first attempt at a scientific article, "A
New Demonstration of the Binomial Theorem."  This I sent to Professor
Henry, secretary of the Smithsonian Institution, to see if he deemed
it suitable for publication.  He promptly replied in the negative, but
offered to submit it to a professional mathematician for an opinion
of its merits.  I gladly accepted this proposal, which was just what
I wanted.  In due course a copy of the report was sent me.  One part
of the work was praised for its elegance, but a lack of completeness
and rigor was pointed out.  It was accompanied by a pleasant note
from Professor Henry remarking that, while not so favorable as I might
have expected, it was sufficiently so to encourage me in persevering.

The other effort to which I refer was of quite a different character.
A copy of the "National Intelligencer," intended for some subscriber
who had left Sudlersville, came to the post-office for several months,
and, there being no claimant, I frequently had an opportunity to
read it.  One of its features was frequent letters from volunteer
writers on scientific subjects.  Among these was a long letter
from one G. W. Eveleth, the object of which was to refute the
accepted theory of the universe, especially the view of Copernicus.
For aught I knew Mr. Eveleth held as high a position as any one else
in the world of science and letters, so I read his article carefully.
It was evidently wholly fallacious, yet so plausible that I feared
the belief of the world in the doctrine of Copernicus might suffer
a severe shock, and hastened to the rescue by writing a letter over
my own name, pointing out the fallacies.  This was published in the
"National Intelligencer"--if my memory serves me right--in 1855.
My full name, printed in large capitals, in a newspaper, at the bottom
of a letter, filled me with a sense of my temerity in appearing so
prominently in print, as if I were intruding into company where I
might not be wanted.

My letter had two most unexpected and gratifying results.  One was
a presentation of a copy of Lee's "Tables and Formulæ," which came
to me a few days later through the mail with the compliments of
Colonel Abert.  Not long afterward came a letter from Professor
J. Lawrence Smith, afterward a member of the National Academy of
Sciences, transmitting a copy of a pamphlet by him on the theory
that meteorites were masses thrown up from the volcanoes of the moon,
and asking my opinion on the subject.

I had not yet gotten into the world of light.  But I felt as one who,
standing outside, could knock against the wall and hear an answering
knock from within.

The beginning of 1856 found me teaching in the family of a planter
named Bryan, residing in Prince George County, Md., some fifteen or
twenty miles from Washington.  This opened up new opportunities.
I could ride into Washington whenever I wished, leave my horse
at a livery stable, and see whatever sights the city offered.
The Smithsonian Library was one of the greatest attractions.
Sometime in May, 1856, I got permission from the attendant in charge
to climb into the gallery and see the mathematical books.  Here I
was delighted to find the greatest treasure that my imagination had
ever pictured,--a work that I had thought of almost as belonging
to fairyland.  And here it was right before my eyes--four enormous
volumes,--"Mécanique Céleste, by the Marquis de Laplace, Peer of
France; translated by Nathaniel Bowditch, LL. D., Member of the
Royal Societies of London, Edinburg, and Dublin."  I inquired as to
the possibility of my borrowing the first volume, and was told that
this could be done only by special authority of Professor Henry.
I soon got the necessary authority through Mr. Rhees, the chief
clerk, whose kindness in the matter deeply impressed me, signed a
promise to return it within one month, and carried it in triumph
to my little schoolhouse.  I dipped into it here and there, but at
every step was met by formulæ and methods quite beyond the power of
one who knew so little of mathematics.  In due time I brought the
book back as promised.

Up to this time I think I had never looked upon a real live
professor; certainly not upon one of eminence in the scientific
world.  I wondered whether there was any possibility of my making the
acquaintance of so great a man as Professor Henry.  Some time previous
a little incident had occurred which caused me some uneasiness on
the subject.  I had started out very early on a visit to Washington,
or possibly I had stayed there all night.  At any rate, I reached
the Smithsonian Building quite early, opened the main door, stepped
cautiously into the vestibule, and looked around.  Here I was met
by a short, stout, and exceedingly gruff sort of a man, who looked
upon my entrance with evident displeasure.  He said scarcely a word,
but motioned me out of the door, and showed me a paper or something
in the entrance which intimated that the Institution would be open
at nine o'clock.  It was some three minutes before that hour so I
was an intruder.  The man looked so respectable and so commanding
in his appearance that I wondered if he could be Professor Henry,
yet sincerely hoped he was not.  I afterward found that he was only
"Old Peake," the janitor. [4]  When I found the real Professor Henry
he received me with characteristic urbanity, told me something of
his own studies, and suggested that I might find something to do in
the Coast Survey, but took no further steps at that time.

The question whether I was fitted for any such employment now became
of great interest.  The principal question was whether one must know
celestial mechanics in order to secure such a position, so, after
leaving Professor Henry, I made my way to the Coast Survey office, and
was shown to the chief clerk, as the authority for the information.
I modestly asked him whether a knowledge of physical astronomy was
necessary to a position in that office.  Instead of frankly telling
me that he did not know what physical astronomy was, he answered in
the affirmative.  So I left with the impression that I must master
the "Mécanique Céleste" or some similar treatise before finding any
opening there.

I could not, of course, be satisfied with a single visit to such
a man, and so called several times during the year.  One thing
I wondered about was whether he would remember me when he again
saw me.  On one occasion I presented him with a plan for improving
the Cavendish method of determining the density of the earth,
which he took very kindly.  I subsequently learned that he was much
interested in this problem.  On another occasion he gave me a letter
to Mr. J. E. Hilgard, assistant in charge of the Coast Survey office.
My reception by the latter was as delightful as that by Professor
Henry.  I found from my first interview with him that the denizens
of the world of light were up to the most sanguine conceptions I
ever could have formed.

At this time, or probably some time before, I bought a copy of the
"American Ephemeris" for 1858, and amused myself by computing on
a slate the occultations visible at San Francisco during the first
few months of the year.  At this time I had learned nothing definite
from Mr. Hilgard as to employment in his office.  But about December,
1856, I received a note from him stating that he had been talking
about me to Professor Winlock, superintendent of the "Nautical
Almanac," and that I might possibly get employment on that work.
When I saw him again I told him that I had not yet acquired
such a knowledge of physical astronomy as would be necessary for
the calculations in question; but he assured me that this was no
drawback, as formulæ for all the computations would be supplied me.
I was far from satisfied at the prospect of doing nothing more than
making routine calculations with formulæ prepared by others; indeed,
it was almost a disappointment to find that I was considered qualified
for such a place.  I could only console myself by the reflection that
the ease of the work would not hinder me from working my way up.
Shortly afterward I understood that it was at least worth while to
present myself at Cambridge, and so started out on a journey thither
about the last day of the year 1856.

At that time even a railroad journey was quite different from what it
is now.  The cars were drawn through Baltimore by horses.  At Havre
de Grace the train had to stop and the passengers were taken across
the river in a ferryboat to another train.  At Philadelphia the city
had to be traversed by transfer coaches.  Looking around for this
conveyance, I met a man who said he had it.  He shoved me into it
and drove off.  I remarked with suspicion that no other coaches were
accompanying us.  After a pretty long drive the speed of the horses
gradually began to slacken.  At length it came to a complete stop in
front of a large building, and I got out.  But it was only a freight
station, locked up and dark throughout.  The driver mumbled something
about his fare, then rolled back on his seat, seemingly dead drunk.
The nearest sign of life was at a tavern a block or two away.  There I
found that I was only a short distance from the station of departure,
and reached my train barely in time.

Landing in New York at the first glimmer of dawn, near the end of the
line of passengers I was momentarily alarmed to see a man pick up what
seemed to be a leather purse from right between my feet.  It was brown
and, so far as I could see, just like my own.  I immediately felt
the breast pocket of my coat and found that my own was quite safe.
The man who picked up the purse inquired in the politest tone possible
if it was mine, to which I replied in the negative.  He retreated a
short distance and then a bystander came up and chided me in a whisper
for my folly in not claiming the purse.  The only reply he got was,
"Oh, I'm up to all your tricks."  On a repetition of this assurance
the pair sneaked away.

Arriving at Cambridge, I sought out Professor Winlock and was
informed that no immediate employment was open at his office.
It would be necessary for him to get authority from Washington.
After this was obtained some hope might be held out, so I appeared
in the office from time to time as a visitor, my first visit being
that described in the opening chapter.

[1] I may remark, for the benefit of any medical reader, that it
involved the use of two pails, one full of water, the other empty.
When he got through the ablution, one pail was empty, and the other
full.  My authority for the actuality of this remarkable proceeding
was some inmate of the house at the time, and I give credence to
the story because it was not one likely to be invented.

[2] Rev. Alexander H. Monroe, who, I have understood, afterward
lived in Montreal.  I have often wished to find a trace of him,
but do not know whether he is still living.

[3] Our druggist was Mr. S. L. Tilley, afterward Sir Leonard Tilley,
the well-known Canadian Minister of Finance.

[4] Peake, notwithstanding his official title, would seem to have
been more than an ordinary janitor, as he was the author of a Guide
to the Smithsonian Institution.




III

THE WORLD OF SWEETNESS AND LIGHT


The term "Nautical Almanac" is an unfortunate misnomer for what is,
properly speaking, the "Astronomical Ephemeris."  It is quite a
large volume, from which the world draws all its knowledge of times
and seasons, the motions of the heavenly bodies, the past and future
positions of the stars and planets, eclipses, and celestial phenomena
generally which admit of prediction.  It is the basis on which the
family almanac is to rest.  It also contains the special data needed
to enable the astronomer and navigator to determine their position on
land or sea.  The first British publication of the sort, prepared by
Maskelyne, Astronomer Royal, a century ago, was intended especially
for the use of navigators; hence the familiar appellation, which I
call unfortunate because it leads to the impression that the work
is simply an enlargement and improvement of the household almanac.

The leading nations publish ephemerides of this sort.  The
introductions and explanations are, of course, in the languages of
the respective countries; but the contents of the volume are now so
much alike that the duplication of work involved in preparing them
seems quite unnecessary.  Yet national pride and emulation will
probably continue it for some time to come.

The first appropriation for an American ephemeris and nautical
almanac was made by Congress in 1849.  Lieutenant Charles Henry
Davis, as a leader and moving spirit in securing the appropriation,
was naturally made the first superintendent of the work.  At that time
astronomical science in our country was so far from being reduced to
a system that it seemed necessary to have the work prepared at some
seat of learning.  So, instead of founding the office in Washington,
it was established at Cambridge, the seat of Harvard University,
where it could have the benefit of the technical knowledge of experts,
and especially of Professor Benjamin Peirce, who was recognized as
the leading mathematician of America.  Here it remained until 1866,
when conditions had so far changed that the office was removed to
Washington, where it has since remained.

To this work I was especially attracted because its preparation seemed
to me to embody the highest intellectual power to which man had ever
attained.  The matter used to present itself to my mind somewhat in
this way: Supply any man with the fundamental data of astronomy, the
times at which stars and planets cross the meridian of a place, and
other matters of this kind.  He is informed that each of these bodies
whose observations he is to use is attracted by all the others with
a force which varies as the inverse square of their distance apart.
From these data he is to weigh the bodies, predict their motion in
all future time, compute their orbits, determine what changes of form
and position these orbits will undergo through thousands of ages,
and make maps showing exactly over what cities and towns on the
surface of the earth an eclipse of the sun will pass fifty years
hence, or over what regions it did pass thousands of years ago.
A more hopeless problem than this could not be presented to the
ordinary human intellect.  There are tens of thousands of men who
could be successful in all the ordinary walks of life, hundreds who
could wield empires, thousands who could gain wealth, for one who
could take up this astronomical problem with any hope of success.
The men who have done it are therefore in intellect the select few
of the human race,--an aristocracy ranking above all others in the
scale of being.  The astronomical ephemeris is the last practical
outcome of their productive genius.

On the question whether the world generally reasoned in this way,
I do not remember having any distinct idea.  This was certainly
not because I was indifferent to the question, but because it never
strongly presented itself to my mind.  From my point of view it would
not have been an important one, because I had already formed the
conviction that one should choose that sphere in life to which he was
most strongly attracted, or for which his faculties best fitted him.

A few months previous to my advent Commander Davis had been
detached from the superintendency and ordered to command the
sloop St. Mary's.  He was succeeded by Professor Joseph Winlock,
who afterward succeeded George P. Bond as director of the Harvard
Observatory.  Most companionable in the society of his friends,
Winlock was as silent as General Grant with the ordinary run of men.
Withal, he had a way of putting his words into exact official form.
The following anecdote of him used to be current.  While he was
attached to the Naval Academy, he was introduced one evening at a
reception to a visiting lady.  He looked at the lady for a decorous
length of time, and she looked at him; then they parted without
saying a word.  His introducer watched the scene, and asked him,
"Why did you not talk to that lady?"

"I had no statement to make to her," was the reply.

Dr. Gould told me this story was founded on fact, but when, after
Winlock's death, it was put off on me with some alterations, I felt
less sure.

The following I believe to be authentic.  It occurred several
years later.  Hilgard, in charge of the Coast Survey office,
was struck by the official terseness of the communications he
occasionally received from Winlock, and resolved to be his rival.
They were expecting additions to their families about the same time,
and had doubtless spoken of the subject.  When Hilgard's arrived,
he addressed a communication to Winlock in these terms:--

"Mine's a boy.  What's yours?"

In due course of time the following letter was received in reply:--

Dear Hilgard:--
  _Boy._
    Yours, etc., J. Winlock.

When some time afterward I spoke to Winlock on the subject, and
told him what Hilgard's motive was, he replied, "It was not fair
in Hilgard to try and take me unawares in that way.  Had I known
what he was driving at, I might have made my letter still shorter."
I did not ask him how he would have done it.  It is of interest that
the "boy" afterward became one of the assistant secretaries of the
Smithsonian Institution.

One of the most remarkable features of the history of the "Nautical
Almanac" is the number of its early assistants who have gained
prominence or distinction in the various walks of life.  It would
be difficult to find so modest a public work to exceed it in this
respect.

John D. Runkle, who lived till 1902, was, as I have said, the
senior and leading assistant in the office.  He afterward became a
professor in the Institute of Technology, and succeeded Rogers as
its president.  In 1876 he started the school of manual training,
which has since been one of the great features of the Institute.
He afterward resigned the presidency, but remained its principal
professor of mathematics.  He was the editor and founder of the
"Mathematical Monthly," of which I shall presently have more to say.

The most wonderful genius in the office, and the one who would have
been the most interesting subject of study to a psychologist, was
Truman Henry Safford.  In early childhood he had excited attention
by his precocity as what is now sometimes called a "lightning
calculator."  A committee of the American Academy of Arts and Science
was appointed to examine him.  It very justly and wisely reported that
his arithmetical powers were not in themselves equal to those of some
others on record, especially Zerah Colburn, but that they seemed to
be the outcome of a remarkable development of the reasoning power.
When nine years old, he computed almanacs, and some of his work
at this age is still preserved in the Harvard University Library.
He graduated at Harvard in 1854, and was soon afterward taken into
the Nautical Almanac Office, while he also worked from time to time
at the Cambridge observatory.  It was found, however, that the power
of continuous work was no greater in him than in others, nor did he
succeed in doing more than others in the course of a year.

The mental process by which certain gifted arithmetical computers
reach almost in an instant the results of the most complicated
calculations is a psychological problem of great interest,
which has never been investigated.  No more promising subject for
the investigation could ever have been found than Safford, and I
greatly regret having lost all opportunities to solve the problem.
What was of interest in Safford's case was the connection of this
faculty with other remarkable mental powers of an analogous but
yet different kind.  He had a remarkable faculty for acquiring,
using, and reading languages, and would have been an accomplished
linguist had he turned his attention in that direction.  He was a
walking bibliography of astronomy, which one had only to consult in
order to learn in a moment what great astronomers of recent times had
written on almost any subject, where their work was published, and on
what shelf of the Harvard Library the book could be found.  But the
faculty most closely connected with calculation was a quickness and
apprehension of vision, of which the following is an example:--

About 1876 he visited the Naval Observatory in Washington for the
first time in his life.  We wanted a certain catalogue of stars and
went together into the library.  The required catalogue was on one
of a tier of shelves containing altogether a hundred, or perhaps
several hundred volumes.  "I do not know whether we have the book,"
said I, "but if we have, it is on one of these shelves."  I began
to go through the slow process of glancing at the books one by one
until my eyes should strike the right title.  He stood back six
or eight feet and took in all the shelves seemingly at one glance,
then stepped forward and said, "Here it is."  I might have supposed
this an accident, but that he subsequently did practically the same
thing in my office, selecting in a moment a book we wanted to see,
after throwing a rapid glance over shelves containing perhaps a
hundred volumes.

An example of his apprehension and memory for numbers was narrated
by Mr. Alvan Clark.  When the latter had completed one of his great
telescopes for the University of Chicago, Safford had been named
as director, and accompanied the three members of the firm to the
city when they carried the object glass thither.  On leaving the
train all four took their seats in a hotel omnibus, Safford near
the door.  Then they found that they had forgotten to give their
baggage checks to the expressman; so the other three men passed
their checks to Safford, who added his own and handed all four to
the conductor of the omnibus.  When it was time for the baggage to
come to the hotel, there was such a crowd of new arrivals that the
attendants could not find it.  The hotel clerk remarked on inquiry,
"If I only knew the numbers of your checks, I would have no difficulty
in tracing your trunks."  Safford at once told off the four numbers,
which he had read as he was passing the checks to the conductor.

The great fire practically put an end to the activity of the Chicago
Observatory and forced its director to pursue his work in other
fields.  That he failed to attain that commanding position due to his
genius is to be ascribed to a cause prevalent among us during all the
middle part of the century; perhaps that from which most brilliant
intellects fail to reach eminence: lack of the power of continuous
work necessary to bring important researches to a completion.

Another great intellect of the office was Chauncey Wright.
If Wright had systematically applied his powers, he might have
preceded or supplanted Herbert Spencer as the great exponent of the
theory of evolution.  He had graduated at Harvard in 1853, and was
a profound student of philosophy from that time forward, though I am
not aware that he was a writer.  When in 1858 Sir William Hamilton's
"Lectures on Metaphysics" appeared, he took to them with avidity.
In 1859 appeared Darwin's "Origin of Species," and a series of
meetings was held by the American Academy, the special order of
which was the discussion of this book.  Wright and myself, not yet
members, were invited to be present.  To judge of the interest it is
only necessary to remark that Agassiz and Gray were the two leading
disputants, the first taking ground against Darwin, the other in his
favor.  Wright was a Darwinist from the very beginning, explaining
the theory in private conversation from a master's point of view,
and soon writing upon it in the "North American Review" and in other
publications.  Of one of his articles Darwin has been quoted as saying
that it was the best exposition of his theory that had then appeared.
After his untimely death in 1875, Wright's papers were collected and
published under the title of "Philosophical Discussions." [1]  Their
style is clear-cut and faultless in logical form, yet requiring such
close attention to every word as to be less attractive to the general
reader of to-day than that of Spencer.  In a more leisurely age,
when men wanted to think profoundly as they went along in a book,
and had little to disturb the current of their thoughts, it would
have commanded wide attention among thinking men.

A singular peculiarity which I have sometimes noticed among men of
intelligence is that those who are best informed on the subject
may be most reckless as regards the laws of health.  Wright did
all of his office work in two or three months of the year.  During
those months he worked at his computations far into the hours of
the morning, stimulating his strength with cigars, and dropping
his work only to take it up when he had had the necessary sleep.
A strong constitution might stand this for a few years, as his did.
But the ultimate result hardly needs to be told.

Besides the volume I have mentioned, Wright's letters were collected
and printed after his death by the subscription of his friends.
In these his philosophic views are from time to time brought out
in a light, easy way, much more charming than the style of his
elaborate discussions.  It was in one of his letters that I first
found the apothegm, "Men are born either Platonists or Aristotelians,"
a happy drawing of the line which separates the hard-headed scientific
thinker of to-day from the thinkers of all other classes.

William Ferrell, a much older man than myself, entered the office
about the same time as I did.  He published papers on the motions
of fluids on the earth's surface in the "Mathematical Monthly,"
and became one of the great authorities on dynamic meteorology,
including the mathematical theory of winds and tides.  He was, I
believe, the first to publish a correct theory of the retardation
produced in the rotation of the earth by the action of the tides,
and the consequent slow lengthening of the day.

James Edward Oliver might have been one of the great mathematicians of
his time had he not been absolutely wanting in the power of continuous
work.  It was scarcely possible to get even his year's office
work out of him.  Yet when I once wrote him a question on certain
mathematical forms which arise in the theory of "least squares,"
he replied in a letter which, with some developments and change of
form, would have made a worthy memoir in any mathematical journal.
As a matter of fact, the same thoughts did appear some years after,
in an elaborate paper by Professor J. W. L. Glaisher, of England,
published by the Royal Astronomical Society.

Oliver, who afterward became professor of higher mathematics at
Cornell University, was noted for what I think should be considered
the valuable quality of absent-mindedness.  It was said of him that
he was once walking on the seashore with a small but valuable gold
watch loose in his pocket.  While deep in thought he started a kind
of distraction by picking up flat stones and skipping them on the
water.  Taking his watch from his pocket he skipped it as a stone.
When I became well acquainted with him I took the liberty of asking
him as to the correctness of this story.  He could not positively
say whether it was true or not.  The facts were simply that he had
the watch, that he had walked on the seashore, had skipped stones,
missed the watch at some subsequent time, and never saw it again.

More definite was an observation made on his movements one afternoon
by a looker-out from a window of the Nautical Almanac Office.
Across the way the road was bounded by no fence, simply passing
along the side of an open field.  As Oliver got near the office,
his chin on his breast, deep in thought, he was seen gradually to
deviate from the sidewalk, and direct his steps along the field.
He continued on this erratic course until he ran almost against the
fence at the other end.  This awoke him from his reverie, and he
started up, looked around, and made his way back to the road.

I have spoken only of the men who were employed at the office at
the time I entered.  Previous to my time were several who left to
accept professorships in various parts of the country.  Among them
were Professors Van Vleck, of Middletown, and Hedrick and Kerr, of
North Carolina.  Not desiring to leave upon the mind of the reader the
impression that all of whom I have not spoken remained in obscurity,
I will remark that Mr. Isaac Bradford rose to the position of mayor
of the city of Cambridge, and that fugitive pieces in prose and
poetry by Mr. E. J. Loomis were collected in a volume. [2]

The discipline of the public service was less rigid in the office
at that time than at any government institution I ever heard of.
In theory there was an understanding that each assistant was
"expected" to be in the office five hours a day.  The hours might be
selected by himself, and they generally extended from nine until two,
the latter being at that time the college and family dinner hour.
As a matter of fact, however, the work was done pretty much where
and when the assistant chose, all that was really necessary being
to have it done on time.

It will be seen that the excellent opportunities offered by this
system were well improved by those who enjoyed them--improved in a way
that I fear would not be possible in any other surroundings.  I took
advantage of them by enrolling myself as a student of mathematics in
the Lawrence Scientific School.  On this occasion I well remember
my pleasant reception by Charles W. Eliot, tutor in mathematics,
and E. N. Horsford, professor of chemistry, and, I believe, dean of
the school.  As a newcomer into the world of light, it was pleasant
to feel the spirit with which they welcomed me.  The departments of
chemistry and engineering were about the only ones which, at that
time, had any distinct organization.  As a student of mathematics
it could hardly be said that anything was required of me either in
the way of attendance on lectures or examinations until I came up
for the degree of Bachelor of Science.  I was supposed, however,
to pursue my studies under the direction of Professor Peirce.

So slight a connection with the university does not warrant me in
assuming an authoritative position as an observer of its men or
its workings.  Yet there are many features associated with it which
I have not seen in print, which have probably disappeared with the
progress of the age, and to which, therefore, allusion may be made.
One, as it presents itself to my memory, is the great variety and
picturesqueness of character which the university then presented.
I would like to know whether the changes in men which one fancies he
sees during his passage from youth to age are real, or only relative
to his point of view.  If my impressions are correct, our educational
planing mill cuts down all the knots of genius, and reduces the best
of the men who go through it to much the same standard.  Does not the
Harvard professor of to-day always dine in a dress coat?  Is he not
free from every eccentricity?  Do the students ever call him "Benny"
or "Tobie"?  Is any "Old Soph" [3] now ambulant on the college green?
Is not the administration of the library a combination of liberality
and correctness?  Is such a librarian as John Langdon Sibley possible?

Mr. Sibley, under a rough exterior, was one of the best-hearted and
most admirable of men, with whom I ultimately formed an intimate
friendship.  But our first acquaintance was of a very unfavorable
kind.  It came about in this way: not many days after being taken
into the Nautical Almanac Office I wanted a book from the university
library, and asked a not over-bright old gentleman in the office
what formalities were necessary in order to borrow it.

"Just go over and tell them you want it for the Nautical Almanac."

"But they don't know me at the library, and surely will not give
a book to any stray caller because he says he wants it for the
Nautical Almanac."

"You have only to say 'Nautical Almanac' and you will get the book."

I argued the matter as stoutly as courtesy admitted, but at length,
concluding that I was new to the rules and regulations of the place,
accepted the supposedly superior knowledge of my informer and went
over to the library with a due measure of assurance.  The first
attendant whom I addressed referred me to the assistant librarian,
and he again to the librarian.  After these formalities, conducted
with impressive gravity, my assurance wilted when I was ushered into
the august presence of the chief librarian.

As the mental picture of the ensuing scene has shaped itself through
more than forty years it shows a personage of imposing presence,
gigantic features, and forbidding countenance, standing on a dais
behind a desk, expounding the law governing the borrowing of books
from the library of Harvard College to an abashed youth standing
before him.  I left without the book, but with a valuable addition
to my knowledge of library management.  We both remembered this
interview, and exchanged impressions about it long years after.

"I thought you the most crusty and disobliging old man I had ever
seen."

"And I thought _you_ the most presumptuous youth that had ever
appeared in the library."

One of Mr. Sibley's professional doctrines was that at least one copy
of everything printed was worth preserving.  I strove to refute him,
but long failed.  Half in derision, I offered the library the stub
of my wash-book.  Instead of throwing it into the wastebasket he
kept it, with the remark that the wash-book of a nineteenth century
student would at some future time be of interest to the antiquarian.
In due time I received a finely engraved acknowledgment of the gift.
But I forced him from his position at last.  He had to admit that
copies of the theatre posters need not all be preserved.  It would
suffice to keep a few specimens.

Professor Peirce was much more than a mathematician.  Like many men
of the time, he was a warm lover and a cordial hater.  It could not
always be guessed which side of a disputed question he would take;
but one might be fairly sure that he would be at one extreme or
the other.  As a speaker and lecturer he was very pleasing, neither
impressive nor eloquent, and yet interesting from his earnestness
and vivacity.  For this reason it is said that he was once chosen
to enforce the views of the university professors at a town meeting,
where some subject of interest to them was coming up for discussion.
Several of the professors attended the meeting, and Peirce made
his speech.  Then a townsman rose and took the opposite side,
expressing the hope that the meeting would not allow itself to be
dictated to by these nabobs of Harvard College.  When he sat down,
Peirce remained in placid silence, making no reply.  When the meeting
broke up, some one asked Peirce why he had not replied to the man.

"Why! did you not hear what he called us?  He said we were nabobs!
I so enjoyed sitting up there and seeing all that crowd look up to
me as a nabob that I could not say one word against the fellow."

The first of the leading astronomers whose acquaintance I made
was Dr. Benjamin Apthorp Gould.  Knowing his eminence, I was
quite surprised by his youthful vivacity.  His history, had I time
to recount it, might be made to serve well the purpose of a grave
lesson upon the conditions required, even by the educated public, of
a scientific investigator, capable of doing the highest and best work
in his branch.  The soul of generosity and the pink of honor, ever
ready to lend a hand to a struggling youth whom he found deserving
of help, enthusiastically devoted to his favorite science, pursuing
it in the most exalted spirit, animated by not a single mean motive,
it might have been supposed that all the facilities the world could
offer would have been open to him in his career.  If such was not the
case to the extent one might have wished, I do not mean to intimate
that his life can be regarded as a failure.  In whatever respect
the results may have fallen off from his high ideal, it is more to
be regretted on the score of science than on his own.

Scorning pretense and charlatanry of all kinds, believing that
only the best were to be encouraged, he was far from being a man
of the people.  Only a select few enjoyed his favor, but these few
well deserved it.  That no others would have deserved it I should
be far from intimating.  The undisguised way in which he expressed
his sentiments for any one, no matter how influential, who did not
come up to the high standard he set, was not adapted to secure the
favor even of the most educated community.  Of worldly wisdom in
this matter he seemed, at least in his early days, to know nothing.

He graduated at Harvard in 1845, in one of the very distinguished
classes.  Being fond of astronomy, he was struck with the backward
condition of that science in our country.  He resolved to devote his
life to building up the science in America.  He went to Germany,
then the only country in which astronomy was pursued in its most
advanced form, studied under Gauss and Argelander, and took his
degree at Göttingen in 1848.  Soon after his return he founded the
"Astronomical Journal," and also took a position as Chief of the
Longitude Department in the Coast Survey.

The great misfortune of his life, and temporarily at least, a severe
blow to American astronomy, were associated with his directorship of
the Dudley Observatory at Albany.  This institution was founded by
the munificence of a wealthy widow of Albany.  The men to whom she
intrusted the administration of her gift were among the most prominent
and highly respected citizens of the place.  The trustees went wisely
to work.  They began by forming an advisory scientific council,
consisting of Bache, Henry, and Peirce.  Under the direction of this
council the observatory was built and equipped with instruments.
When ready for active work in 1857, Gould moved thither and took
personal charge.  Very soon rumors of dissension were heard.
The affair gradually grew into a contest between the director and
the trustees, exceeding in bitterness any I have ever known in the
world of learning or even of politics.  It doubtless had its origin
in very small beginnings.  The policy of the director recognized no
end but scientific efficiency.  The trustees, as the responsible
administrators of the trust, felt that they had certain rights in
the matter, especially that of introducing visitors to inspect the
institution and look through the telescope.  How fatal the granting
of such courtesies is to continuous work with an instrument only
astronomers know; and one of the most embarrassing difficulties the
director of such an institution meets with is to effect a prudent
compromise between the scientific efficiency of his institution and
the wishes of the public.  But Gould knew no such word as compromise.
It was humiliating to one in the position of a trustee to send some
visitor with a permit to see the observatory, and have the visitor
return with the report that he had not been received with the most
distinguished courtesy, and, perhaps, had not seen the director at
all, but had only been informed by an assistant of the rules of the
place and the impossibility of securing admission.

This spark was enough to kindle a fire.  When the fire gathered
strength, the director, instead of yielding, called on the scientific
council for aid.  It is quite likely that, had these wise and prudent
men been consulted at each step, and their advice been followed, he
would have emphasized his protest by resigning.  But before they were
called in, the affair had gone so far that, believing the director
to be technically right in the ground he had taken and the work he
had done, the council felt bound to defend him.  The result was a
war in which the shots were pamphlets containing charges, defenses,
and rejoinders.  The animosity excited may be shown by the fact
that the attacks were not confined to Gould and his administration,
but extended to every institution with which he and the president of
the council were supposed to be connected.  Bache's administration of
the Coast Survey was held up to scorn and ridicule.  It was supposed
that Gould, as a Cambridge astronomer, was, as a matter of course,
connected with the Nautical Almanac Office, and paid a high salary.
This being assumed, the office was included in the scope of attack,
and with such success that the item for its support for the year 1859,
on motion of Mr. Dawes, was stricken out of the naval bill.  How far
the fire spread may be judged by the fact that a whole edition of the
"Astronomical Journal," supposed to have some mention of the affair
in the same cover, was duly sent off from the observatory, but never
reached its destination through the mails.  Gould knew nothing of
this fact until, some weeks later, I expressed my surprise to him
at not receiving No. 121.  How or by whom it was intercepted, I do
not know that he ever seriously attempted to inquire.  The outcome
of the matter was that the trustees asserted their right by taking
forcible possession of the observatory.

During my first year at Cambridge I made the acquaintance of a
senior in the college whose untimely death seven years later I have
never ceased to deplore.  This was William P. G. Bartlett, son of a
highly esteemed Boston physician, Dr. George Bartlett.  The latter
was a brother of Sidney Bartlett, long the leader of the Boston bar.
Bartlett was my junior in years, but his nature and the surrounding
circumstances were such that he exercised a powerful influence
upon me.  His virile and aggressive honesty could not be exceeded.
His mathematical abilities were of a high order, and he had no
ambition except to become a mathematician.  Had he entered public
life at Washington, and any one had told me that he was guilty of a
dishonest act, I should have replied, "You might as well tell me that
he picked up the Capitol last night and carried it off on his back."
The fact that one could say so much of any man, I have always looked
upon as illustrating one of the greatest advantages of having a youth
go through college.  The really important results I should look for
are not culture or training alone, but include the acquaintance of
a body of men, many of whom are to take leading positions in the
world, of a completeness and intimacy that can never be acquired
under other circumstances.  The student sees his fellow students
through and through as he can never see through a man in future years.

It was, and I suppose still is, the custom for the members of a
graduating class at Harvard to add to their class biographies a
motto expressing their aspirations or views of life.  Bartlett's was,
"I love mathematics and hate humbug."  What the latter clause would
have led to in his case, had he gone out into the world, one can
hardly guess.

"I have had a long talk with my Uncle Sidney," he said to me one day.
"He wants me to study law, maintaining that the wealth one can thereby
acquire, and the prominence he may assume, will give him a higher
position in society and public esteem than mere learning ever can.
But I told him that if I could stand high in the esteem of twenty such
men as Cayley, Sylvester, and Peirce, I cared nothing to be prominent
in the eyes of the rest of the world."  Such an expression from an
eminent member of the Boston bar, himself a Harvard graduate, was the
first striking evidence I met with that my views of the exalted nature
of astronomical investigation were not shared by society at large.
One of the greatest advantages I enjoyed through Bartlett was an
intimate acquaintance with a cultured and refined Boston family.

In 1858 Mr. Runkle founded the "Mathematical Monthly," having
secured, in advance, the coöperation of the leading professors
of the subject in the country.  The journal was continued, under
many difficulties, for three years.  As a vehicle for publishing
researches in advanced mathematics, it could not be of a high order,
owing to the necessity of a subscription list.  Its design was
therefore to interest students and professors in the subject, and
thus prepare the way for the future growth of mathematical study
among us.  Its principal feature was the offer of prize problems
to students as well as prizes for essays on mathematical subjects.
The first to win a prize for an essay was George W. Hill, a graduate
of Rutgers just out of college, who presented a memoir in which the
hand of the future master was evident throughout.

In the general conduct of the journal Bartlett and myself, though not
ostensibly associate editors, were at least assistants.  Simple though
the affair was, some of our experiences were of an interesting and,
perhaps, instructive nature.

Soon after the first number appeared, a contribution was offered by
a professor in a distant State.  An important part of the article
was found to be copied bodily from Walton's "Problems in Mechanics,"
an English book which, it might be supposed, was not much known in
this country.  Runkle did not want to run the risk of injuring his
subscription list by offending one occupying an influential position
if he could help it with honor to the journal.  Of course it was not
a question of publishing the paper, but only of letting the author
know why he did not do so,--"letting him down easy."

Bartlett's advice was characteristic.  "Just write to the fellow
that we don't publish stolen articles.  That's all you need say."

I suggested that we might inflict on him all necessary humiliation
by letting him know in the gentlest manner possible that we saw
the fraud.  Of course Runkle preferred this course, and wrote him,
calling his attention to a similarity between his treatment of
the subject and that of Walton, which materially detracted from the
novelty of the former.  I think it was suggested that he get the book,
if possible, and assure himself on the subject.

A vigorous answer came by return of mail.  He was a possessor of
Walton's book, knew all about the similar treatment of the subject by
Walton, and did not see that that should be any bar to the publication
of the article.  I think it was he who wound up his letter with the
statement that, while he admitted the right of the editor to publish
what he pleased, he, the writer, was too busy to spend his time in
writing rejected articles.

An eminent would-be contributor was a prominent Pennsylvania
politician, who had read a long and elaborate article, before some
teachers' association, on an arithmetical problem about oxen eating
grass, the power to solve which was taken as the highest mark of
mathematical ability, among school teachers during the first half
of the century.  The association referred the paper to the editor
of the "Mathematical Monthly," by whom it was, I believe, consigned
to the wastebasket.  The result was a good deal of correspondence,
such a proceeding being rather humiliating to a man of eminence
who had addressed so distinguished an assembly.  The outcome of the
matter was that the paper, which was much more in the nature of a
legal document than of a mathematical investigation, was greatly
reduced in length by its author, and then still further shorn by the
editor, until it would fill only two or three pages of the journal;
thus reduced, it was published.

The time was not yet ripe for the growth of mathematical science
among us, and any development that might have taken place in that
direction was rudely stopped by the civil war.  Perhaps this may
account for the curious fact that, so far as I have ever remarked,
none of the student contributors to the journal, Hill excepted,
has made himself known as a mathematical investigator.  Not only
the state of mathematical learning, but the conditions of success
at that time in a mathematical text-book, are strikingly illustrated
by one of our experiences.

One of the leading publishing houses of educational text-books in
the country issued a very complete and advanced series, from the
pen of a former teacher of the subject.  They were being extensively
introduced, and were sent to the "Mathematical Monthly" for review.
They were distinguished by quite apt illustrations, well fitted,
perhaps, to start the poorly equipped student in the lower branches of
the work, but the advanced works, at least, were simply ridiculous.
A notice appeared in which the character of the books was pointed
out.  The evidence of the worthlessness of the entire series was
so strong that the publishers had it entirely rewritten by more
competent authors.  Now came the oddest part of the whole affair.
The new series was issued under the name of the same author as the
old one, just as if the acknowledgment of his total failure did not
detract from the value of his name as an author.

In 1860 a total eclipse of the sun was visible in British America.
The shadow of the moon, starting from near Vancouver's Island,
crossed the continent in a northeast direction, passed through the
central part of the Hudson Bay region, crossed Hudson Bay itself and
Greenland, then inclining southward, swept over the Atlantic to Spain.
As this was the first eclipse of the kind which had recently been
visible, much interest was taken in its observation.  On the part of
the Nautical Almanac Office I computed the path of the shadow and
the times of crossing certain points in it.  The results were laid
down on a map which was published by the office.  One party, fitted
out in connection with the American Association for the Advancement
of Science, was sent to Greenland.  Admiral Davis desired to send
another, on behalf of his own office, into the central regions of
the continent.  As members of this party Mr. Ferrel and myself were
chosen.  At the request of Professor Agassiz one of the assistants in
the Museum of Comparative Zoölogy, Mr. Samuel H. Scudder, accompanied
us.  More than twenty years later Mr. Scudder published a little book
describing some of our adventures, which was illustrated with sketches
showing the experiences of a party in the wild West at that time.

Our course lay from St. Paul across Minnesota to the Red River of
the North, thence north to Fort Garry near the southern end of Lake
Winnipeg, then over the lake and some distance up the Saskatchewan
River.  At St. Paul we paid our respects to Governor Ramsey, afterward
Senator from Minnesota and Secretary of War.  We were much surprised
at the extraordinary deference paid by the community to a Mr. Burbank,
a leading citizen of the town, and owner of the stages which we had
to engage for our journey across the country.  He seemed to be a man
whom every one was afraid to offend.  Even the local newspapers were
careful what they printed about matters in which he was interested.

The two or three days which we passed in getting things ready
to start were rather dull.  The morning after our arrival I saw,
during a morning walk, on a hill just outside the town, a large new
building, on which the word "Athenæum" was conspicuously shown.
The Boston Athenæum had a very fine library; is it not possible
that this may have a beginning of something of the same sort?
Animated by this hope, I went up the hill and entered the building,
which seemed to be entirely vacant.  The first words that met my
eyes were "Bar Room" painted over a door.  It was simply a theatre,
and I left it much disappointed.

Here we were joined by a young Methodist clergyman,--Edward
Eggleston,--and the four of us, with our instruments and appliances,
set out on our journey of five days over the plains.  On the
first day we followed partly the line of a projected railway, of
which the embankments had been completed, but on which work had,
for some reason, been stopped to await a more prosperous season.
Here was our first experience of towns on paper.  From the tone in
which the drivers talked of the places where we were to stop over
night one might have supposed that villages, if not cities, were
plentiful along our track.  One example of a town at that time will
be enough.  The principal place on our route, judging from the talk,
was Breckenridge.  We would reach it at the end of the fourth day,
where we anticipated a pleasant change after camping out in our tent
for three nights.  It was after dark before we arrived, and we looked
eagerly for signs of the town we were approaching.

The team at length stopped in front of an object which, on careful
examination in the darkness, appeared to be the most primitive
structure imaginable.  It had no foundations, and if it had a
wall at all, it was not more than two or three feet in height.
Imagine the roof taken off a house forty feet long and twenty feet
wide and laid down on the ground, and you have the hotel and only
building, unless perhaps a stable, in Breckenridge at that time.
The entrance was at one end.  Going in, a chimney was seen in the
middle of the building.  The floor was little more than the bare
ground.  On each side of the door, by the flickering light of a fire,
we saw what looked like two immense boxes.  A second glance showed
that these boxes seemed to be filled with human heads and legs.
They were, in fact, the beds of the inhabitants of Breckenridge.
Beds for the arriving travelers, if they existed at all, which I do
not distinctly remember, were in the back of the house.  I think the
other members of the party occupied that portion.  I simply spread
my blanket out on the hearth in front of the fire, wrapped up,
and slept as soundly as if the bed was the softest of a regal palace.

At Fort Garry we were received by Governor McTavish, with whom Captain
Davis had had some correspondence on the subject of our expedition,
and who gave us letters to the "factors" of the Hudson Bay Company
scattered along our route.  We found that the rest of our journey
would have to be made in a birch bark canoe.  One of the finest craft
of this class was loaned us by the governor.  It had been, at some
former time, the special yacht of himself or some visiting notable.
It was manned by eight half-breeds, men whose physical endurance I
have never seen equaled.

It took three or four days to get everything ready, and this interval
was, of course, utilized by Scudder in making his collections.
He let the fishermen of the region know that he wanted specimens of
every kind of fish that could be found in the lake.  A very small
reward stirred them into activity, and, in due time, the fish were
brought to the naturalist,--but lo! all nicely dressed and fit for
cooking.  They were much surprised when told that all their pains in
dressing their catch had spoiled it for the purposes of the visiting
naturalist, who wanted everything just as it was taken from the water.

Slow indeed was progress through the lake.  A canoe can be paddled
only in almost smooth water, and we were frequently stormbound on some
desolate island or point of land for two or three days at a time.
When, after many adventures, some of which looked like hairbreadth
escapes, we reached the Saskatchewan River, the eclipse was only three
or four days ahead, and it became doubtful whether we should reach
our station in time for the observation.  It was to come off on the
morning of July 18, and, by dint of paddling for twenty-four hours
at a stretch, our men brought us to the place on the evening before.

Now a new difficulty occurred.  In the wet season the Saskatchewan
inundates the low flat region through which it flows, much like
the Nile.  The country was practically under water.  We found the
most elevated spot we could, took out our instruments, mounted
them on boxes or anything else in the shallow puddles of water, and
slept in the canoe.  Next morning the weather was hopelessly cloudy.
We saw the darkness of the eclipse and nothing more.

Astronomers are greatly disappointed when, having traveled halfway
around the world to see an eclipse, clouds prevent a sight of it;
and yet a sense of relief accompanies the disappointment.  You are
not responsible for the mishap; perhaps something would have broken
down when you were making your observations, so that they would
have failed in the best of weather; but now you are relieved from
all responsibility.  It was much easier to go back and tell of
the clouds than it would have been to say that the telescope got
disarranged at the critical moment so that the observations failed.

On our return across Minnesota we had an experience which I have
always remembered as illustrative of the fallacy of all human
testimony about ghosts, rappings, and other phenomena of that
character.  We spent two nights and a day at Fort Snelling.  Some of
the officers were greatly surprised by a celestial phenomenon of a
very extraordinary character which had been observed for several
nights past.  A star had been seen, night after night, rising in
the east as usual, and starting on its course toward the south.
But instead of continuing that course across the meridian, as stars
invariably had done from the remotest antiquity, it took a turn
toward the north, sunk toward the horizon, and finally set near the
north point of the horizon.  Of course an explanation was wanted.
My assurance that there must be some mistake in the observation could
not be accepted, because this erratic course of the heavenly body
had been seen by all of them so plainly that no doubt could exist on
the subject.  The men who saw it were not of the ordinary untrained
kind, but graduates of West Point, who, if any one, ought to be free
from optical deceptions.  I was confidently invited to look out that
night and see for myself.  We all watched with the greatest interest.

In due time the planet Mars was seen in the east making its way
toward the south.  "There it is!" was the exclamation.

"Yes, there it is," said I.  "Now that planet is going to keep right
on its course toward the south."

"No, it is not," said they; "you will see it turn around and go down
towards the north."

Hour after hour passed, and as the planet went on its regular course,
the other watchers began to get a little nervous.  It showed no
signs of deviating from its course.  We went out from time to time
to look at the sky.

"There it is," said one of the observers at length, pointing to
Capella, which was now just rising a little to the east of north;
"there is the star setting."

"No, it is n't," said I; "there is the star we have been looking at,
now quite inconspicuous near the meridian, and that star which you
think is setting is really rising and will soon be higher up."

A very little additional watching showed that no deviation of the
general laws of Nature had occurred, but that the observers of
previous nights had jumped at the conclusion that two objects,
widely apart in the heavens, were the same.

I passed more than four years in such life, surroundings, and
activities as I have described.  In 1858 I received the degree of
D. S. from the Lawrence Scientific School, and thereafter remained
on the rolls of the university as a resident graduate.  Life in the
new atmosphere was in such pleasant and striking contrast to that
of my former world that I intensely enjoyed it.  I had no very well
marked object in view beyond continuing studies and researches in
mathematical astronomy.  Not long after my arrival in Cambridge some
one, in speaking of Professor Peirce, remarked to me that he had a
European reputation as a mathematician.  It seemed to me that this
was one of the most exalted positions that a man could attain, and I
intensely longed for it.  Yet there was no hurry.  Reputation would
come to him who deserved it by his works; works of the first class
were the result of careful thought and study, and not of hurry.
A suggestion had been made to me looking toward a professorship in
some Western college, but after due consideration, I declined to
consider the matter.  Yet the necessity of being on the alert for
some opening must have seemed quite strong, because in 1860 I became
a serious candidate for the professorship of physics in the newly
founded Washington University at St. Louis.  I was invited to visit
the university, and did so on my way to observe the eclipse of 1860.
My competitor was Lieutenant J. M. Schofield of the United States
Army, then an instructor at West Point.  It will not surprise the
reader to know that the man who was afterward to command the army
of the United States received the preference, so I patiently waited
more than another year.

IV

LIFE AND WORK AT AN OBSERVATORY


In August, 1861, while I was passing my vacation on Cape Ann,
I received a letter from Dr. Gould, then in Washington, informing
me that a vacancy was to be filled in the corps of professors of
mathematics attached to the Naval Observatory, and suggesting that
I might like the place.  I was at first indisposed to consider
the proposition.  Cambridge was to me the focus of the science
and learning of our country.  I feared that, so far as the world
of learning was concerned, I should be burying myself by moving
to Washington.  The drudgery of night work at the observatory would
also interfere with carrying on any regular investigation.  But, on
second thought, having nothing in view at the time, and the position
being one from which I could escape should it prove uncongenial,
I decided to try, and indited the following letter:--

    Nautical Almanac Office,
   Cambridge, Mass., August 22, 1861.

 Sir,--I have the honor to apply to you for my appointment
 to the office of Professor of Mathematics in the United
 States Navy.  I would respectfully refer you to Commander
 Charles Henry Davis, U. S. N., Professor Benjamin Peirce,
 of Harvard University, Dr. Benjamin A. Gould, of Cambridge,
 and Professor Joseph Henry, Secretary of the Smithsonian
 Institution, for any information respecting me which will
 enable you to judge of the propriety of my appointment.

  With high respect,
   Your obedient servant,
    Simon Newcomb,
   Assistant, Nautical Almanac.

 Hon. Gideon Welles,
  Secretary of the Navy,
   Washington, D. C.

I also wrote to Captain Davis, who was then on duty in the Navy
Department, telling him what I had done, but made no further effort.
Great was my surprise when, a month later, I found in the post-office,
without the slightest premonition, a very large official envelope,
containing my commission duly signed by Abraham Lincoln, President
of the United States.  The confidence in the valor, abilities, etc.,
of the appointee, expressed in the commission, was very assuring.
Accompanying it was a letter from the Secretary of the Navy
directing me to report to the Bureau of Ordnance and Hydrography,
in Washington, for such duty as it might assign me.  I arrived on
October 6, and immediately called on Professor J. S. Hubbard, who was
the leading astronomer of the observatory.  On the day following I
reported as directed, and was sent to Captain Gilliss, the recently
appointed Superintendent of the Naval Observatory, before whom I
stood with much trepidation.  In reply to his questions I had to
confess my entire inexperience in observatory work or the making
of astronomical observations.  A coast survey observer had once
let me look through his transit instrument and try to observe the
passage of a star.  On the eclipse expedition mentioned in the last
chapter I had used a sextant.  This was about all the experience
in practical astronomy which I could claim.  In fact I had never
been inside of an observatory, except on two or three occasions at
Cambridge as a visitor.  The captain reassured me by saying that
no great experience was expected of a newcomer, and told me that I
should go to work on the transit instrument under Professor Yarnall,
to whose care I was then confided.

As the existence of a corps of professors of mathematics is peculiar
to our navy, as well as an apparent, perhaps a real, anomaly,
some account of it may be of interest.  Early in the century--one
hardly knows when the practice began--the Secretary of the Navy,
in virtue of his general powers, used to appoint men as professors
of mathematics in the navy, to go to sea and teach the midshipmen
the art of navigation.  In 1844, when work at the observatory was
about to begin, no provision for astronomers was made by Congress.
The most convenient way of supplying this want was to have the
Secretary appoint professors of mathematics, and send them to the
observatory on duty.

A few years later the Naval Academy was founded at Annapolis, and a
similar course was pursued to provide it with a corps of instructors.
Up to this time the professors had no form of appointment except
a warrant from the Secretary of the Navy.  Early in the history of
the academy the midshipmen burned a professor in effigy.  They were
brought before a court-martial on the charge of disrespect to a
superior officer, but pleaded that the professor, not holding a
commission, was not their superior officer, and on this plea were
acquitted.  Congress thereupon took the matter up, provided that
the number of professors should not exceed twelve, and that they
should be commissioned by the President by and with the advice
and consent of the Senate.  This raised their rank to that of a
commissioned corps in the navy.  They were to perform such duty as
the Secretary of the Navy might direct, and were, for the most part,
divided between the Naval Academy and the Observatory.

During the civil war some complaint was made that the midshipmen
coming from the academy were not well trained in the duties of a
seagoing officer; and it was supposed that this was due to too much
of their time being given to scientific studies.  This was attributed
to the professors, with the result that nearly all those attached to
the academy were detached during the four years following the close
of the civil war and ordered elsewhere, mostly to the observatory.
Their places were taken by line officers who, in the intervals between
their turns of sea duty, were made heads of departments and teachers
of the midshipmen in nearly every branch.

This state of things led to the enactment of a law (in 1869, I think),
"that hereafter no vacancy in the grade of professors of mathematics
in the navy shall be filled."

In 1873 this provision was annulled by a law, again providing
for a corps of twelve professors, three of whom should have the
relative rank of captain, four of commander, and the remainder of
lieutenant-commander or lieutenant.

Up to 1878 the Secretary of the Navy was placed under no restrictions
as to his choice of a professor.  He could appoint any citizen whom
he supposed to possess the necessary qualifications.  Then it was
enacted that, before appointment, a candidate should pass a medical
and a professional examination.

I have said that the main cause of hesitation in making my
application arose from my aversion to very late night work.  It soon
became evident that there was less ground than I had supposed for
apprehension on this point.  There was a free and easy way of carrying
on work which was surprising to one who had supposed it all arranged
on strict plans, and done according to rule and discipline.  Professor
Yarnall, whose assistant I was, was an extremely pleasant gentleman
to be associated with.  Although one of the most industrious workers
at the observatory, there was nothing of the martinet about him.
He showed me how to handle the instrument and record my observations.
There was a Nautical Almanac and a Catalogue of Stars.  Out of these
each of us could select what he thought best to observe.

The custom was that one of us should come on every clear evening,
make observations as long as he chose, and then go home.  The transit
instrument was at one end of the building and the mural circle, in
charge of Professor Hubbard, at the other.  He was weak in health,
and unable to do much continuous work of any kind, especially the
hard work of observing.  He and I arranged to observe on the same
nights; but I soon found that there was no concerted plan between
the two sets of observers.  The instruments were old-fashioned
ones, of which mine could determine only the right ascension of a
star and his only its declination; hence to completely determine
the position of a celestial body, observations must be made on the
same object with both instruments.  But I soon found that there was
no concert of action of this kind.  Hubbard, on the mural circle,
had his plan of work; Yarnall and myself, on the transit, had ours.
When either Hubbard or myself got tired, we could "vote it cloudy"
and go out for a plate of oysters at a neighboring restaurant.

In justice to Captain Gilliss it must be said that he was not in
any way responsible for this lack of system.  It grew out of the
origin and history of the establishment and the inaction of Congress.
The desirableness of our having a national observatory of the same
rank as those of other countries was pointed out from time to time by
eminent statesmen from the first quarter of the century.  John Quincy
Adams had, both while he filled the presidential office and afterward,
made active efforts in this direction; but there were grave doubts
whether Congress had any constitutional authority to erect such an
institution, and the project got mixed up with parties and politics.
So strong was the feeling on the subject that, when the Coast Survey
was organized, it was expressly provided that it should not establish
an astronomical observatory.

The outcome of the matter was that, in 1842, when Congress at length
decided that we should have our national observatory, it was not
called such, but was designated as a "house" to serve as a depot
for charts and instruments for the navy.  But every one knew that
an observatory was meant.  Gilliss was charged with its erection,
and paid a visit to Europe to consult with astronomers there on
its design, and to order the necessary instruments.  When he got
through with this work and reported it as completed he was relieved,
and Lieutenant Matthew F. Maury was appointed superintendent of the
new institution.

Maury, although (as he wrote a few years later) quite without
experience in the use of astronomical instruments, went at his work
with great energy and efficiency, so that, for two or three years,
the institution bade fair to take a high place in science.  Then he
branched off into what was, from a practical standpoint, the vastly
more important work of studying the winds and currents of the ocean.
The epoch-making character of his investigations in this line,
and their importance to navigation when ships depended on sails for
their motive power, were soon acknowledged by all maritime nations,
and the fame which he acquired in pursuing them added greatly to
the standing of the institution at which the work was done, though
in reality an astronomical outfit was in no way necessary to it.
The new work was so absorbing that he seemed to have lost interest
in the astronomical side of the establishment, which he left to his
assistants.  The results were that on this side things fell into the
condition I have described, and stayed there until Maury resigned his
commission and cast his fortunes with the Confederacy.  Then Gilliss
took charge and had to see what could be done under the circumstances.

It soon became evident to him that no system of work of the first
order of importance could be initiated until the instrumental
equipment was greatly improved.  The clocks, perfection in
which is almost at the bottom of good work, were quite unfit
for use.  The astronomical clock with which Yarnall and I made
our observations kept worse time than a high-class pocket watch
does to-day.  The instruments were antiquated and defective in
several particulars.  Before real work could be commenced new ones
must be procured.  But the civil war was in progress, and the times
were not favorable to immediately securing them.  That the work of
the observatory was kept up was due to a feeling of pride on the
part of our authorities in continuing it without interruption through
the conflict.  The personnel was as insufficient as the instruments.
On it devolved not only the making of the astronomical observations,
but the issue of charts and chronometers to the temporarily immense
navy.  In fact the observatory was still a depot of charts for the
naval service, and continued to be such until the Hydrographic Office
was established in 1866.

In 1863 Gilliss obtained authority to have the most pressing wants
supplied by the construction of a great transit circle by Pistor and
Martins in Berlin.  He had a comprehensive plan of work with this
instrument when it should arrive, but deferred putting any such plan
in operation until its actual reception.

Somehow the work of editing, explaining, and preparing for the
press the new series of observations made by Yarnall and myself with
our old transit instrument devolved on me.  To do this in the most
satisfactory way, it was necessary to make a careful study of the
methods and system at the leading observatories of other countries
in the line we were pursuing, especially Greenwich.  Here I was
struck by the superiority of their system to ours.  Everything was
there done on an exact and uniform plan, and one which seemed to
me better adapted to get the best results than ours was.  For the
non-astronomical reader it may be remarked that after an astronomer
has made and recorded his observations, a large amount of calculation
is necessary to obtain the result to which they lead.  Making such
calculations is called "reducing" the observations.  Now in the
previous history of the observatory, the astronomers fell into the
habit of every one not only making his observations in his own way,
but reducing them for himself.  Thus it happened that Yarnall had
been making and reducing his observations in his own way, and I,
on alternate nights, had been making and reducing mine in my way,
which was modeled after the Greenwich fashion, and therefore quite
different from his.  Now I suddenly found myself face to face with
the problem of putting these two heterogeneous things together so
as to make them look like a homogeneous whole.  I was extremely
mortified to see how poor a showing would be made in the eyes of
foreign astronomers.  But I could do nothing more than to describe
the work and methods in such a way as to keep in the background the
want of system that characterized them.

Notwithstanding all these drawbacks of the present, the prospect
of future success seemed brilliant.  Gilliss had the unlimited
confidence of the Secretary of the Navy, had a family very popular
in Washington society, was enthusiastically devoted to building
up the work of the observatory, and was drawing around him the
best young men that could be found to do that work.  He made it a
point that his relations with his scientific subordinates should
be not only official, but of the most friendly social character.
All were constantly invited to his charming family circle.  It was
from the occasional talks thus arising that I learned the details
of his plan of work with the coming instrument.

In 1862 Gilliss had the working force increased by the appointment of
four "aides," as they were then called,--a number that was afterwards
reduced to three.  This was the beginning of the corps of three
assistant astronomers, which is still maintained.  It will be of
interest to know that the first aide was Asaph Hall; but before his
appointment was made, an impediment, which for a time looked serious,
had to be overcome.  Gilliss desired that the aide should hold a
good social and family position.  The salary being only $1000, this
required that he should not be married.  Hall being married, with
a growing family, his appointment was long objected to, and it was
only through much persuasion on the part of Hubbard and myself that
Gilliss was at length induced to withdraw his objections.  Among other
early appointees were William Harkness and John A. Eastman, whose
subsequent careers in connection with the observatory are well known.

The death of Professor Hubbard in 1863 led to my taking his place,
in charge of the mural circle, early in September of that year.
This gave me an opportunity of attempting a little improvement
in the arrangements.  I soon became conscious of the fact, which
no one had previously taken much account of, that upon the plan of
each man reducing his own observations, not only was there an entire
lack of homogeneity in the work, but the more work one did at night
the more he had to do by day.  It was with some trepidation that I
presented the case to Gilliss, who speedily saw that work done with
the instruments should be regarded as that of the observatory, and
reduced on a uniform plan, instead of being considered as the property
of the individual who happened to make it.  Thus was introduced the
first step toward a proper official system.

In February, 1865, the observatory sustained the greatest loss
it had ever suffered, in the sudden death of its superintendent.
What it would have grown to had he lived it is useless to guess,
but there is little doubt that its history would have been quite
different from what it is.

Soon afterward Admiral Davis left his position as Chief of the
Bureau of Navigation to take the subordinate one of Superintendent
of the Observatory.  This step was very gratifying to me, Davis had
not only a great interest in scientific work, especially astronomy,
but a genuine admiration of scientific men which I have never seen
exceeded, accompanied with a corresponding love of association with
them and their work.

In October, 1865, occurred what was, in my eyes, the greatest event
in the history of the observatory.  The new transit circle arrived
from Berlin in its boxes.  Now for the first time in its history, the
observatory would have a meridian instrument worthy of it, and would,
it was hoped, be able to do the finest work in at least one branch
of astronomy.  To my great delight, Davis placed me in charge of it.
The last three months of the year were taken up with mounting it
in position and making those investigations of its peculiarities
which are necessary before an instrument of the kind is put into
regular use.  On the 1st day of January, 1866, this was all done,
and we were ready to begin operations.  An opportunity thus arose
of seeing what we could do in the way of a regular and well-planned
piece of work.  In the greater clearness of our sky, and the more
southern latitude of our observatory, we had two great advantages
over Greenwich.  Looking back at his first two or three years of
work at the observatory, Maury wrote to a friend, "We have beaten
Greenwich hollow."  It may be that I felt like trying to do the
same thing over again.  At any rate, I mapped out a plan of work
the execution of which would require four years.

It was a piece of what, in astronomy, is called "fundamental work,"
in which results are to be obtained independent of any previously
obtained by other observers.  It had become evident to me from our
own observations, as well as from a study of those made at European
observatories, that an error in the right ascension of stars, so
that stars in opposite quarters of the heavens would not agree, might
very possibly have crept into nearly all the modern observations at
Greenwich, Paris, and Washington.  The determination of this error
was no easy matter.  It was necessary that, whenever possible,
observations should be continued through the greater part of the
twenty-four hours.  One observer must be at work with comparative
steadiness from nine o'clock in the morning until midnight or even
dawn of the morning following.  This requirement was, however, less
exacting than might appear when stated.  One half the nights would,
as a general rule, be cloudy, and an observer was not expected to
work on Sunday.  Hence no one of the four observers would probably
have to do such a day's work as this more than thirty or forty times
in a year.

All this was hard work enough in itself, but conditions existed which
made it yet harder.  No houses were then provided for astronomers,
and the observatory itself was situated in one of the most unhealthy
parts of the city.  On two sides it was bounded by the Potomac, then
pregnant with malaria, and on the other two, for nearly half a mile,
was found little but frame buildings filled with quartermaster's
stores, with here and there a few negro huts.  Most of the observers
lived a mile or more from the observatory; during most of the time I
was two miles away.  It was not considered safe to take even an hour's
sleep at the observatory.  The result was that, if it happened to
clear off after a cloudy evening, I frequently arose from my bed
at any hour of the night or morning and walked two miles to the
observatory to make some observation included in the programme.

This was certainly a new departure from the free and easy way in which
we had been proceeding, and it was one which might be unwelcome to
any but a zealous astronomer.  As I should get the lion's share of
credit for its results, whether I wanted to or not, my interest in the
work was natural.  But it was unreasonable to expect my assistants,
one or two of whom had been raised to the rank of professor, to feel
the same interest, and it is very creditable to their zeal that we
pursued it for some time as well as we did.  If there was any serious
dissatisfaction with the duty, I was not informed of that fact.

During the second year of this work Admiral Davis was detached and
ordered to sea.  The question of a successor interested many besides
ourselves.  Secretary Welles considered the question what policy
should be pursued in the appointment.  Professor Henry took part in
the matter by writing the secretary a letter, in which he urged the
appointment of an astronomer as head of the institution.  His position
prevented his supporting any particular candidate; so he submitted
a list of four names, any one of which would be satisfactory.
These were: Professor William Chauvenet, Dr. B. A. Gould, Professor
J. H. C. Coffin, U. S. N., and Mr. James Ferguson.  The latter held
a civil position at the observatory, under the title of "assistant
astronomer," and was at the time the longest in service of any of
its force.

A different view was urged upon the secretary in terms substantially
these: "Professors so able as those of the observatory require no
one to direct their work.  All that the observatory really needs
is an administrative head who shall preserve order, look after
its business generally, and see that everything goes smoothly."
Such a head the navy can easily supply.

The secretary allowed it to be given out that he would be glad to
hear from the professors upon the subject.  I thereupon went to
him and expressed my preference for Professor Coffin.  He asked me,
"How would it do to have a purely administrative head?"

I replied that we might get along for a time if he did not interfere
with our work.

"No," said the secretary, "he shall not interfere.  That shall
be understood."

As I left him there was, to my inexperienced mind, something very
odd in this function, or absence of function, of the head of an
establishment; but of course I had to bow to superior wisdom and
could say nothing.

The policy of Commodore (afterward Rear-Admiral) Sands, the incoming
superintendent, toward the professors was liberal in the last degree.
Each was to receive due credit for what he did, and was in every way
stimulated to do his best at any piece of scientific work he might
undertake with the approval of the superintendent.  Whether he wanted
to observe an eclipse, determine the longitude of a town or interior
station, or undertake some abstruse investigation, every facility
for doing it and every encouragement to go on with it was granted him.

Under this policy the observatory soon reached the zenith of
its fame and popularity.  Whenever a total eclipse of the sun was
visible in an accessible region parties were sent out to observe it.
In 1869 three professors, I being one, were sent to Des Moines,
Iowa, to observe the solar eclipse which passed across the country
in June of that year.  As a part of this work, I prepared and the
observatory issued a detailed set of instructions to observers in
towns at each edge of the shadow-path to note the short duration of
totality.  The object was to determine the exact point to which the
shadow extended.  At this same eclipse Professor Harkness shared with
Professor Young of Princeton the honor of discovering the brightest
line in the spectrum of the sun's corona.  The year following parties
were sent to the Mediterranean to observe an eclipse which occurred
in December, 1870.  I went to Gibraltar, although the observation of
the eclipse was to me only a minor object.  Some incidents connected
with this European trip will be described in a subsequent chapter.

The reports of the eclipse parties not only described the scientific
observations in great detail, but also the travels and experiences,
and were sometimes marked by a piquancy not common in official
documents.  These reports, others pertaining to longitude, and
investigations of various kinds were published in full and distributed
with great liberality.  All this activity grew out of the stimulating
power and careful attention to business of the head of the observatory
and the ability of the young professors of his staff.  It was very
pleasant to the latter to wear the brilliant uniform of their rank,
enjoy the protection of the Navy Department, and be looked upon,
one and all, as able official astronomers.  The voice of one of our
scientific men who returned from a visit abroad declaring that one
of our eclipse reports was the laughing-stock of Europe was drowned
in the general applause.

In the latter part of 1869 I had carried forward the work with
the transit circle as far as it could be profitably pursued under
existing conditions.  On working up my observations, the error which
I had suspected in the adopted positions of the stars was proved
to be real.  But the discovery of this error was due more to the
system of observation, especially the pursuit of the latter through
the day and night, than it was to any excellence of the instrument.
The latter proved to have serious defects which were exaggerated by
the unstable character of the clayey soil of the hill on which the
observatory was situated.  Other defects also existed, which seemed
to preclude the likelihood that the future work of the instrument
would be of a high class.  I had also found that very difficult
mathematical investigations were urgently needed to unravel one
of the greatest mysteries of astronomy, that of the moon's motion.
This was a much more important work than making observations, and
I wished to try my hand at it.  So in the autumn I made a formal
application to the Secretary of the Navy to be transferred from
the observatory to the Nautical Almanac Office for the purpose of
engaging in researches on the motion of the moon.  On handing this
application to the superintendent he suggested that the work in
question might just as well be done at the observatory.  I replied
that I thought that the business of the observatory was to make and
reduce astronomical observations with its instruments, and that the
making of investigations of the kind I had in view had always been
considered to belong to the Nautical Almanac Office.  He replied that
he deemed it equally appropriate for the observatory to undertake it.
As my objection was founded altogether on a principle which he
refused to accept, and as by doing the work at the observatory
I should have ready access to its library, I consented to the
arrangement he proposed.  Accordingly, in forwarding my application,
he asked that my order should be so worded as not to detach me from
the observatory, but to add the duty I asked for to that which I
was already performing.

So far as I was personally concerned, this change was fortunate
rather than otherwise.  As things go in Washington, the man who
does his work in a fine public building can gain consideration for
it much more readily than if he does it in a hired office like that
which the "Nautical Almanac" then occupied.  My continued presence
on the observatory staff led to my taking part in two of the great
movements of the next ten years, the construction and inauguration
of the great telescope and the observations of the transit of Venus.
But for the time being my connection with the regular work of the
observatory ceased.

On the retirement of Admiral Sands in 1874, Admiral Davis returned
to the observatory, and continued in charge until his death in
February, 1877.  The principal event of this second administration
was the dispatch of parties to observe the transit of Venus.  Of this
I shall speak in full in a subsequent chapter.

One incident, although of no public importance, was of some interest
at the time.  This was a visit of the only emperor who, I believe,
had ever set foot on our shores,--Dom Pedro of Brazil.  He had
chosen the occasion of our Centennial for a visit to this country,
and excited great interest during his stay, not only by throwing
off all imperial reserve during his travels, but by the curiosity
and vigor with which he went from place to place examining and
studying everything he could find, and by the singular extent of
his knowledge on almost every subject of a scientific or technical
character.  A Philadelphia engineer with whom he talked was quoted
as saying that his knowledge of engineering was not merely of the
ordinary kind to be expected in an intelligent man, but extended
to the minutest details and latest improvements in the building of
bridges, which was the specialty of the engineer in question.

Almost as soon as he arrived in Washington I received the following
letter by a messenger from the Arlington Hotel:--

    Mr.:
 En arrivant à Washington j'ai tout-de-suite songé à votre
 observatoire, où vous avez acquis tant de droit à l'estime
 de tout ceux qui achèvent la science.  Je m'y rendrai donc
 aujourd'hui à 7 heures du soir, et je compte vous y trouver,
 surtout pour vous remercier de votre beau mémoire que j'ai
 reçu peu avant mon départ de mon pays, et que je n'ai pas
 pu, par conséquent, apprécier autant que je l'aurais voulu.
 En me plaisant de l'espoir de vous connaître personnellement
 je vous prie de me compter parmi vos affectionnés.
    D. Pedro D'Alcantara.
 7 Mai, 1876.

Like other notes which I subsequently received from him, it was in
his own autograph throughout: if he brought any secretary with him
on his travels I never heard of it.

The letter placed me in an embarrassing position, because its being
addressed to me was in contravention of all official propriety.
Of course I lost no time in calling on him and trying to explain the
situation.  I told him that Admiral Davis, whom he well knew from
his being in command of the Brazilian station a few years before,
was the head of the observatory, and hinted as plainly as I could
that a notification of the coming of such a visitor as he should
be sent to the head of the institution.  But he refused to take
the hint, and indicated that he expected me to arrange the whole
matter for him.  This I did by going to the observatory and frankly
explaining the matter to Admiral Davis.  Happily the latter was not
a stickler for official forms, and was cast in too large a mould to
take offense where none was intended.  At his invitation I acted as
one of the receiving party.  The carriage drove up at the appointed
hour, and its occupant was welcomed by the admiral at the door with
courtly dignity.  The visitor had no time to spend in preliminaries;
he wished to look through the establishment immediately.

The first object to meet his view was a large marble-cased clock
which, thirty years before, had acquired some celebrity from being
supposed to embody the first attempt to apply electricity to the
recording of astronomical observations.  It was said to have cost
a large sum, paid partly as a reward to its inventor.  Its only
drawbacks were that it would not keep time and had never, so far as
I am aware, served any purpose but that of an ornament.  The first
surprise came when the visitor got down on his hands and knees in
front of the clock, reached his hands under it, and proceeded to
examine its supports.  We all wondered what it could mean.  When he
arose, it was explained.  He did not see how a clock supported in this
way could keep the exact time necessary in the work of an astronomer.
So we had to tell him that the clock was not used for this purpose,
and that he must wait until we visited the observing rooms to see
our clocks properly supported.

The only evidence of the imperial will came out when he reached the
great telescope.  The moon, near first quarter, was then shining,
but the night was more than half cloudy, and there was no hope of
obtaining more than a chance glimpse at it through the clouds.
But he wished to see the moon through the telescope.  I replied
that the sky was now covered, and it was very doubtful whether we
should get a view of the moon.  But he required that the telescope
should be at once pointed at it.  This was done, and at that moment a
clear space appeared between the clouds.  I remarked upon the fact,
but he seemed to take it as a matter of course that the cloud would
get out of the way when he wanted to look.

I made some remark about the "vernier" of one of the circles on
the telescope.

"Why do you call it a vernier?" said he.  "Its proper term is a
nonius, because Nonius was its inventor and Vernier took the idea
from him."

In this the national spirit showed itself.  Nonius, a Portuguese,
had invented something on a similar principle and yet essentially
different from the modern vernier, invented by a Frenchman of
that name.

Accompanying the party was a little girl, ten or twelve years old,
who, though an interested spectator, modestly kept in the background
and said nothing.  On her arrival home, however, she broke her
silence by running upstairs with the exclamation,--

"Oh, Mamma, he's the funniest emperor you ever did see!"

My connection with the observatory ceased September 15, 1877, when
I was placed in charge of the Nautical Almanac Office.  It may not,
however, be out of place to summarize the measures which have since
been taken both by the Navy Department and by eminent officers of
the service to place the work of the institution on a sound basis.
One great difficulty in doing this arises from the fact that neither
Congress nor the Navy Department has ever stated the object which
the government had in view in erecting the observatory, or assigned
to it any well-defined public functions.  The superintendent and his
staff have therefore been left to solve the question what to do from
time to time as best they could.

In the spring of 1877 Rear-Admiral John Rodgers became the
superintendent of the observatory.  As a cool and determined fighter
during the civil war he was scarcely second even to Farragut, and he
was at the same time one of the ablest officers and most estimable
men that our navy ever included in its ranks.  "I would rather be
John Rodgers dead than any other man I know living," was said by
one of the observatory assistants after his death.  Not many months
after his accession he began to consider the question whether the wide
liberty which had been allowed the professors in choosing their work
was adapted to attain success.  The Navy Department also desired to
obtain some expressions of opinion on the subject.  The result was
a discussion and an official paper, not emanating from the admiral,
however, in which the duty of the head of the observatory was defined
in the following terms:--

"The superintendent of the observatory should be a line officer of
the navy, of high rank, who should attend to the business affairs
of the institution, thus leaving the professors leisure for their
proper work."

Although he did not entirely commit himself to this view, he was under
the impression that to get the best work out of the professors their
hearts must be in it; and this would not be the case if any serious
restraint was placed upon them as to the work they should undertake.

After Rodgers's death Vice-Admiral Rowan was appointed superintendent.
About this time it would seem that the department was again disposed
to inquire into the results of the liberal policy heretofore pursued.
Commander (since Rear-Admiral) William T. Sampson was ordered to the
observatory, not as its head, but as assistant to the superintendent.
He was one of the most proficient men in practical physics that the
navy has ever produced.  I believe that one reason for choosing
so able and energetic an officer for the place was to see if any
improvement could be made on the system.  As I was absent at the
Cape of Good Hope to observe the transit of Venus during the most
eventful occasion of his administration, I have very little personal
knowledge of it.  It seems, however, that newspaper attacks were made
on him, in which he was charged with taking possession of all the
instruments of the observatory but two, and placing them in charge
of naval officers who were not proficient in astronomical science.
In reply he wrote an elaborate defense of his action to the "New
York Herald," which appeared in the number for February 13, 1883.
The following extract is all that need find a place in the present
connection.

 When I came here on duty a little more than a year since,
 I found these instruments disused.  The transit instrument
 had not been used since 1878, and then only at intervals for
 several years previous; the mural circle had not been used
 since 1877; the prime vertical had not been used since 1867.
 These instruments had been shamefully neglected and much
 injured thereby. . . .  The small equatorial and comet
 seeker were in the same disgraceful condition, and were
 unfit for any real work.

Admiral Franklin was made superintendent sometime in 1883, I believe,
and issued an order providing that the work of the observatory should
be planned by a board consisting of the superintendent, the senior
line officer, and the senior professor.  Professors or officers
in charge of instruments were required to prepare a programme for
their proposed work each year in advance, which programme would be
examined by the board.  Of the work of this board or its proceedings,
no clear knowledge can be gleaned from the published reports, nor
do I know how long it continued.

In 1885 Secretary Whitney referred to the National Academy of Sciences
the question of the advisability of proceeding promptly with the
erection of a new naval observatory upon the site purchased in 1880.
The report of the academy was in the affirmative, but it was added
that the observatory should be erected and named as a national
one, and placed under civilian administration.  The year following
Congress made the preliminary appropriation for the commencement of
the new building, but no notice was taken of the recommendation of
the academy.

In 1891 the new buildings were approaching completion, and Secretary
Tracy entered upon the question of the proper administration of
the observatory.  He discussed the subject quite fully in his annual
report for that year, stating his conclusion in the following terms:--

 I therefore recommend the adoption of legislation which
 shall instruct the President to appoint, at a sufficient
 salary, without restriction, from persons either within or
 outside the naval service, the ablest and most accomplished
 astronomer who can be found for the position of
 superintendent.

At the following session of Congress Senator Hale introduced an
amendment to the naval appropriation bill, providing for the expenses
of a commission to be appointed by the Secretary of the Navy,
to consider and report upon the organization of the observatory.
The House non-concurred in this amendment, and it was dropped from
the bill.

At the same session, all the leading astronomers of the country
united in a petition to Congress, asking that the recommendation of
the Secretary of the Navy should be carried into effect.  After a
very patient hearing of arguments on the subject by Professor Boss
and others, the House Naval Committee reported unanimously against
the measure, claiming that the navy had plenty of officers able to
administer the observatory in a satisfactory way, and that there
was therefore no necessity for a civilian head.

Two years later, Senator Morrill offered an amendment to the
legislative appropriation bill, providing that the superintendent of
the observatory should be selected from civil life, and be learned
in the science of astronomy.  He supported his amendment by letters
from a number of leading astronomers of the country in reply to
questions which he had addressed to them.

This amendment, after being approved by the Senate Naval Committee,
was referred by the Committee on Appropriations to the Secretary
of the Navy.  He recommended a modification of the measure so
as to provide for the appointment of a "Director of Astronomy,"
to have charge of the astronomical work of the observatory, which
should, however, remain under a naval officer as superintendent.
This arrangement was severely criticised in the House by Mr. Thomas
B. Reed, of Maine, and the whole measure was defeated in conference.

In 1892, when the new observatory was being occupied, the
superintendent promulgated regulations for its work.  These set forth
in great detail what the observatory should do.  Its work was divided
into nine departments, each with its chief, besides which there
was a chief astronomical assistant and a chief nautical assistant
to the superintendent, making eleven chiefs in all.  The duties of
each chief were comprehensively described.  As the entire scientific
force of the observatory numbered some ten or twelve naval officers,
professors, and assistant astronomers, with six computers, it may
be feared that some of the nine departments were short-handed.

In September, 1894, new regulations were established by the Secretary
of the Navy, which provided for an "Astronomical Director," who
was to "have charge of and to be responsible for the direction,
scope, character, and preparation for publication of all work purely
astronomical, which is performed at the Naval Observatory."  As there
was no law for this office, it was filled first by the detail of
Professor Harkness, who served until his retirement in 1899, then
by the detail of Professor Brown, who served until March, 1901.

In 1899 the Secretary of the Navy appointed a Board of Visitors
to the observatory, comprising Senator Chandler, of New Hampshire,
Hon. A. G. Dayton, House of Representatives, and Professors Pickering,
Comstock, and Hale.  This board, "in order to obviate a criticism
that the astronomical work of the observatory has not been prosecuted
with that vigor and continuity of purpose which should be shown in
a national observatory," recommended that the Astronomical Director
and the Director of the Nautical Almanac should be civil officers,
with sufficient salaries.  A bill to this effect was introduced
into each House of Congress at the next session, and referred to
the respective naval committees, but never reported.

In 1901 Congress, in an amendment to the naval appropriation bill,
provided a permanent Board of Visitors to the observatory, in whom
were vested full powers to report upon its condition and expenditures,
and to prescribe its plan of work.  It was also provided in the same
law that the superintendent of the observatory should, until further
legislation by Congress, be a line officer of the navy of a rank not
below that of captain.  In the first annual report of this board is
the following clause:--

"We wish to record our deliberate and unanimous judgment that the
law should be changed so as to provide that the official head of
the observatory--perhaps styled simply the Director--should be an
eminent astronomer appointed by the President by and with the consent
of the Senate."

Although the board still has a legal existence, Congress, in
1902, practically suspended its functions by declining to make any
appropriation for its expenses.  Moreover, since the detachment of
Professor Brown, Astronomical Director, no one has been appointed to
fill the vacancy thus arising.  At the time of the present writing,
therefore, the entire responsibility for planning and directing
the work of the observatory is officially vested in the naval
superintendent, as it was at the old observatory.




V

GREAT TELESCOPES AND THEIR WORK


One hardly knows where, in the history of science, to look for an
important movement that had its effective start in so pure and simple
an accident as that which led to the building of the great Washington
telescope, and went on to the discovery of the satellites of Mars.
Very different might have been a chapter of astronomical history,
but for the accident of Mr. Cyrus Field, of Atlantic cable fame,
having a small dinner party at the Arlington Hotel, Washington, in the
winter of 1870.  Among the guests were Senators Hamlin and Casserly,
Mr. J. E. Hilgard of the Coast Survey, and a young son of Mr. Field,
who had spent the day in seeing the sights of Washington.  Being
called upon for a recital of his experiences, the youth described his
visit to the observatory, and expressed his surprise at finding no
large telescope.  The only instrument they could show him was much
smaller and more antiquated than that of Mr. Rutherfurd in New York.

The guests listened to this statement with incredulity, and applied to
Mr. Hilgard to know whether the visitor was not mistaken, through a
failure to find the great telescope of the observatory.  Mr. Hilgard
replied that the statement was quite correct, the observatory having
been equipped at a time when the construction of great refracting
telescopes had not been commenced, and even their possibility was
doubted.

"This ought not to be," said one of the senators.  "Why is it so?"

Mr. Hilgard mentioned the reluctance of Congress to appropriate
money for a telescope.

"It must be done," replied the senator.  "You have the case properly
represented to Congress, and we will see that an appropriation goes
through the Senate at least."

It chanced that this suggestion had an official basis which was not
known to the guests.  Although Mr. Alvan Clark had already risen into
prominence as a maker of telescopes, his genius in this direction
had not been recognized outside of a limited scientific circle.
The civil war had commenced just as he had completed the largest
refracting telescope ever made, and the excitement of the contest,
as well as the absorbing character of the questions growing out
of the reconstruction of the Union, did not leave our public men
much time to think about the making of telescopes.  Mr. Clark had,
however, been engaged by Captain Gilliss only a year or two after the
latter had taken charge of the observatory, to come to Washington,
inspect our instruments, and regrind their glasses.  The result
of his work was so striking to the observers using the instruments
before and after his work on them, that no doubt of his ability could
be felt.  Accordingly, in preparing items for the annual reports of
the observatory for the years 1868 and 1869, I submitted one to the
superintendent setting forth the great deficiency of the observatory
in respect to the power of its telescope, and the ability of Mr. Clark
to make good that deficiency.  These were embodied in the reports.
It was recommended that authority be given to order a telescope of
the largest size from Mr. Clark.

It happened, however, that Secretary Welles had announced in his
annual reports as his policy that he would recommend no estimates for
the enlargement and improvement of public works in his department,
but would leave all matters of this kind to be acted on by Congress
as the latter might deem best.  As the telescope was thrown out of
the regular estimates by this rule, this subject had failed to be
considered by Congress.

Now, however, the fact of the recommendation appearing in the annual
report, furnished a basis of action.  Mr. Hilgard did not lose a
day in setting the ball in motion.

He called upon me immediately, and I told him of the recommendations
in the last two reports of the superintendent of the observatory.
Together we went to see Admiral Sands, who of course took the warmest
interest in the movement, and earnestly promoted it on the official
side.  Mr. Hilgard telegraphed immediately to some leading men of
science, who authorized their signatures to a petition.  In this paper
attention was called to the wants of the observatory, as set forth
by the superintendent, and to the eminent ability of the celebrated
firm of the Clarks to supply them.  The petition was printed and put
into the hands of Senator Hamlin for presentation to the Senate only
three or four days after the dinner party.  The appropriation measure
was formally considered by the Committee on Naval Affairs and that on
Appropriations, and was adopted in the Senate as an amendment to the
naval appropriation bill without opposition.  The question then was
to get the amendment concurred in by the House of Representatives.
The session was near its close, and there was no time to do much work.

Several members of the House Committee on Appropriations were
consulted, and the general feeling seemed to be favorable to
the amendment.  Great, therefore, was our surprise to find the
committee recommending that the amendment be not concurred in.
To prevent a possible misapprehension, I may remark that the present
system of non-concurring in all amendments to an appropriation bill,
in order to bring the whole subject into conference, had not then
been introduced, so that this action showed a real opposition to the
movement.  One of the most curious features of the case is that the
leader in the opposition was said to be Mr. Washburn, the chairman
of the committee, who, not many years later, founded the Washburn
Observatory of the University of Wisconsin.  There is, I believe,
no doubt that his munificence in this direction arose from what he
learned about astronomy and telescopes in the present case.

It happened, most fortunately, that the joint committee of conference
included Drake of the Senate and Niblack of the House, both earnestly
in favor of the measure.  The committee recommended concurrence,
and the clause authorizing the construction became a law.  The price
was limited to $50,000, and a sum of $10,000 was appropriated for
the first payment.

No sooner were the Clarks consulted than difficulties were found
which, for a time, threatened to complicate matters, and perhaps delay
the construction.  In the first place, our currency was then still
on a paper basis.  Gold was at a premium of some ten or fifteen per
cent., and the Clarks were unwilling to take the contract on any but
a gold basis.  This, of course, the Government could not do.  But the
difficulty was obviated through the action of a second one, which
equally threatened delay.  Mr. L. J. McCormick, of reaping-machine
fame, had conceived the idea of getting the largest telescope that
could be made.  He had commenced negotiations with the firm of Alvan
Clark & Sons before we had moved, and entered into a contract while
the appropriation was still pending in Congress.  If the making of
one great telescope was a tedious job, requiring many years for its
completion, how could two be made?

I was charged with the duty of negotiating the government contract
with the Clarks.  I found that the fact of Mr. McCormick's
contract being on a gold basis made them willing to accept one
from the Government on a currency basis; still they considered that
Mr. McCormick had the right of way in the matter of construction,
and refused to give precedence to our instrument.  On mature
consideration, however, the firm reached the conclusion that two
instruments could be made almost simultaneously, and Mr. McCormick
very generously waived any right he might have had to precedence in
the matter.

The question how large an instrument they would undertake was, of
course, one of the first to arise.  Progress in the size of telescopes
had to be made step by step, because it could never be foreseen how
soon the limit might be met; and if an attempt were made to exceed it,
the result would be not only failure for the instrument, but loss
of labor and money by the constructors.  The largest refracting
telescope which the Clarks had yet constructed was one for the
University of Mississippi, which, on the outbreak of the civil war,
had come into the possession of the Astronomical Society of Chicago.
This would have been the last step, beyond which the firm would not
have been willing to go to any great extent, had it not happened that,
at this very time, a great telescope had been mounted in England.
This was made by Thomas Cooke & Sons of York, for Mr. R. S. Newall of
Gateshead on Tyne, England.  The Clarks could not, of course, allow
themselves to be surpassed or even equaled by a foreign constructor;
yet they were averse to going much beyond the Cooke telescope in size.
Twenty-six inches aperture was the largest they would undertake.
I contended as strongly as I could for a larger telescope than
Mr. McCormick's, but they would agree to nothing of the sort,--the
supposed right of that gentleman to an instrument of equal size being
guarded as completely as if he had been a party to the negotiations.
So the contract was duly made for a telescope of twenty-six inches
clear aperture.

At that time Cooke and Clark were the only two men who had ever
succeeded in making refracting telescopes of the largest size.  But in
order to exercise their skill, an art equally rare and difficult
had to be perfected, that of the glassmaker.  Ordinary glass,
even ordinary optical glass, would not answer the purpose at all.
The two disks, one of crown glass and the other of flint, must be not
only of perfect transparency, but absolutely homogeneous through and
through, to avoid inequality of refraction, and thus cause all rays
passing through them to meet in the same focus.  It was only about the
beginning of the century that flint disks of more than two or three
inches diameter could be made.  Even after that, the art was supposed
to be a secret in the hands of a Swiss named Guinand, and his family.
Looking over the field, the Clarks concluded that the only firm that
could be relied on to furnish the glass was that of Chance & Co., of
Birmingham, England.  So, as soon as the contracts were completed,
one of the Clark firm visited England and arranged with Chance &
Co. to supply the glass for the two telescopes.  The firm failed in
a number of trials, but by repeated efforts finally reached success
at the end of a year.  The glasses were received in December,
1871, and tested in the following month.  A year and a half more
was required to get the object glasses into perfect shape; then,
in the spring or summer of 1873, I visited Cambridge for the purpose
of testing the glasses.  They were mounted in the yard of the Clark
establishment in a temporary tube, so arranged that the glass could
be directed to any part of the heavens.

I have had few duties which interested me more than this.  The
astronomer, in pursuing his work, is not often filled with those
emotions which the layman feels when he hears of the wonderful power
of the telescope.  Not to say anything so harsh as that "familiarity
breeds contempt," we must admit that when an operation of any sort
becomes a matter of daily business, the sentiments associated with
it necessarily become dulled.  Now, however, I was filled with
the consciousness that I was looking at the stars through the most
powerful telescope that had ever been pointed at the heavens, and
wondered what mysteries might be unfolded.  The night was of the
finest, and I remember, sweeping at random, I ran upon what seemed
to be a little cluster of stars, so small and faint that it could
scarcely have been seen in a smaller instrument, yet so distant
that the individual stars eluded even the power of this instrument.
What cluster it might have been it was impossible to determine,
because the telescope had not the circles and other appliances
necessary for fixing the exact location of an object.  I could
not help the vain longing which one must sometimes feel under such
circumstances, to know what beings might live on planets belonging
to what, from an earthly point of view, seemed to be a little colony
on the border of creation itself.

In his report dated October 9, 1873, Admiral Sands reported
the telescope as "nearly completed."  The volume of Washington
observations showed that the first serious observations made with it,
those on the satellites of Neptune, were commenced on November 10
of the same year.  Thus, scarcely more than a month elapsed from
the time that the telescope was reported still incomplete in the
shop of its makers until it was in regular nightly use.

Associated with the early history of the instrument is a chapter
of astronomical history which may not only instruct and amuse the
public, but relieve the embarrassment of some astronomer of a future
generation who, reading the published records, will wonder what became
of an important discovery.  If the faith of the public in the absolute
certainty of all astronomical investigation is thereby impaired,
what I have to say will be in the interest of truth; and I have no
fear that our science will not stand the shock of the revelation.
Of our leading astronomical observers of the present day--of such
men as Burnham and Barnard--it may be safely said that when they
see a thing it is there.  But this cannot always be said of every
eminent observer, and here is a most striking example of this fact.

When the telescope was approaching completion I wrote to the head of
one of the greatest European observatories, possessing one of the best
telescopes of the time, that the first thing I should attempt with
the telescope would be the discovery of the companion of Procyon.
This first magnitude star, which may be well seen in the winter
evenings above Orion, had been found to move in an exceedingly small
orbit, one too small to be detected except through the most refined
observations of modern precision.  The same thing had been found in
the case of Sirius, and had been traced to the action of a minute
companion revolving around it, which was discovered by the Clarks
a dozen years before.  There could be no doubt that the motion of
Procyon was due to the same cause, but no one had ever seen the
planet that produced it, though its direction from the star at any
time could be estimated.

Now, it happened that my European friend, as was very natural, had
frequently looked for this object without seeing it.  Whether my
letter set him to looking again, or whether he did not receive
it until a later day, I do not know.  What is certain is that,
in the course of the summer, he published the discovery of the
long-looked-for companion, supplemented by an excellent series of
observations upon it, made in March and April.

Of course I was a little disappointed that the honor of first
finding this object did not belong to our own telescope.  Still I was
naturally very curious to see it.  So, on the very first night on
which the telescope could be used, I sat up until midnight to take
a look at Procyon, not doubting that, with the greater power of our
telescope, it would be seen at the first glance.  To my great concern,
nothing of the sort was visible.  But the night was far from good,
the air being somewhat thick with moisture, which gave objects seen
through it a blurred appearance; so I had to await a better night and
more favorable conditions.  Better nights came and passed, and still
not a trace of the object could be seen.  Supposing that the light
of the bright star might be too dazzling, I cut it off with a piece
of green glass in the focus.  Still no companion showed itself.
Could it be that our instrument, in a more favorable location,
would fail to show what had been seen with one so much smaller?
This question I could not answer, but wrote to my European friend
of my unavailing attempts.

He replied expressing his perplexity and surprise at the occurrence,
which was all the greater that the object had again been seen and
measured in April, 1874.  A fine-looking series of observations
was published, similar to those of the preceding year.  What made
the matter all the more certain was that there was a change in the
direction of the object which corresponded very closely to the motion
as it had been predicted by Auwers.  The latter published a revision
of his work, based on the new observations.

A year later, the parties that had been observing the transit of Venus
returned home.  The head of one of them, Professor C. H. F. Peters
of Clinton, stopped a day or two at Washington.  It happened that
a letter from my European friend arrived at the same time.  I found
that Peters was somewhat skeptical as to the reality of the object.
Sitting before the fire in my room at the observatory, I read to
him and some others extracts from the letter, which cited much
new evidence to show the reality of the discovery.  Not only had
several of his own observers seen the object, but it had been seen
and measured on several different nights by a certain Professor Blank,
with a telescope only ten or twelve inches aperture.

"What," said Peters, "has Blank seen it?"

"Yes, so the letter says."

"Then it is n't there!"

And it really was not there.  The maker of the discovery took it
all back, and explained how he had been deceived.  He found that the
telescope through which the observations were made seemed to show a
little companion of the same sort alongside of every very bright star.
Everything was explained by this discovery.  Even the seeming motion
of the imaginary star during the twelve months was accounted for by
the fact that in 1873 Procyon was much nearer the horizon when the
observations were made than it was the year following. [1]

There is a sequel to the history, which may cause its revision by some
astronomer not many years hence.  When the great telescope was mounted
at the Lick Observatory, it is understood that Burnham and Barnard,
whose eyes are of the keenest, looked in vain for the companion
of Procyon.  Yet, in 1895, it was found with the same instrument
by Schaeberle, and has since been observed with the great Yerkes
telescope, as well as by the observers at Mount Hamilton, so that the
reality of the discovery is beyond a doubt.  The explanation of the
failure of Burnham and Barnard to see it is very simple: the object
moves in an eccentric orbit, so that it is nearer the planet at some
points of its orbit than at others.  It was therefore lost in the
rays of the bright star during the years 1887-94.  Is it possible
that it could have been far enough away to be visible in 1873-74?
I need scarcely add that this question must be answered in the
negative, yet it may be worthy of consideration, when the exact
orbit of the body is worked out twenty or thirty years hence.

In my work with the telescope I had a more definite end in view
than merely the possession of a great instrument.  The work of
reconstructing the tables of the planets, which I had long before
mapped out as the greatest one in which I should engage, required
as exact a knowledge as could be obtained of the masses of all
the planets.  In the case of Uranus and Neptune, the two outer
planets, this knowledge could best be obtained by observations on
their satellites.  To the latter my attention was therefore directed.
In the case of Neptune, which has only one satellite yet revealed
to human vision, and that one so close to the planet that the
observations are necessarily affected by some uncertainty, it was
very desirable that a more distant one should be found if it existed.
I therefore during the summer and autumn of 1874 made most careful
search under the most favorable conditions.  But no second satellite
was found.  I was not surprised to learn that the observers with
the great Lick telescope were equally unsuccessful.  My observations
with the instrument during two years were worked up and published,
and I turned the instrument over to Professor Hall in 1875.

The discovery of the satellites of Mars was made two years later,
in August, 1877.  As no statement that I took any interest in the
discovery has ever been made in any official publication, I venture,
with the discoverer's permission, to mention the part that I took
in verifying it.

One morning Professor Hall confidentially showed me his first
observations of an object near Mars, and asked me what I thought
of them.  I remarked, "Why, that looks very much like a satellite."

Yet he seemed very incredulous on the subject; so incredulous
that I feared he might make no further attempt to see the object.
I afterward learned, however, that this was entirely a misapprehension
on my part.  He had been making a careful search for some time,
and had no intention of abandoning it until the matter was cleared
up one way or the other.

The possibility of the object being an asteroid suggested itself.
I volunteered to test this question by looking at the ephemerides
of all the small planets in the neighborhood of Mars.  A very little
searching disproved the possibility of the object belonging to this
class.  One such object was in the neighborhood, but its motion was
incompatible with the measures.

Then I remarked that, if the object were really a satellite, the
measures already made upon it, and the approximately known mass of
the planet, would enable the motion of the satellite to be determined
for a day or two.  Thus I found that on that night the satellite would
be hidden in the early evening by the planet, but would emerge after
midnight.  I therefore suggested to Professor Hall that, if it was
not seen in the early evening, he should wait until after midnight.
The result was in accordance with the prediction,--the satellite
was not visible in the early evening, but came out after midnight.
No further doubt was possible, and the discovery was published.
The labor of searching and observing was so exhausting that Professor
Hall let me compute the preliminary orbit of the satellites from
his early observations.

My calculations and suggestions lost an importance they might
otherwise have claimed, for the reason that several clear nights
followed.  Had cloudy weather intervened, a knowledge of when to
look for the object might have greatly facilitated its recognition.

It is still an open question, perhaps, whether a great refracting
telescope will last unimpaired for an indefinite length of time.
I am not aware that the twin instruments of Harvard and Pulkowa,
mounted in 1843, have suffered from age, nor am I aware that any
of Alvan Clark's instruments are less perfect to-day than when they
left the hands of their makers.  But not long after the discovery of
the satellites of Mars, doubts began to spread in some quarters as to
whether the great Washington telescope had not suffered deterioration.
These doubts were strengthened in the following way: When hundreds of
curious objects were being discovered in the heavens here and there,
observers with small instruments naturally sought to find them.
The result was several discoveries belonging to the same class
as that of the satellite of Procyon.  They were found with very
insignificant instruments, but could not be seen in the large ones.
Professor Hall published a letter in a European journal, remarking
upon the curious fact that several objects were being discovered
with very small instruments, which were invisible in the Washington
telescope.  This met the eye of Professor Wolf, a professor at the
Sorbonne in Paris, as well as astronomer at the Paris Observatory.
In a public lecture, which he delivered shortly afterward, he lamented
the fact that the deterioration of the Washington telescope had gone
so far as that, and quoted Professor Hall as his authority.

The success of the Washington telescope excited such interest the
world over as to give a new impetus to the construction of such
instruments.  Its glass showed not the slightest drawbacks from its
great size.  It had been feared that, after a certain limit, the
slight bending of the glass under its own weight would be injurious
to its performance.  Nothing of the kind being seen, the Clarks were
quite ready to undertake much larger instruments.  A 30-inch telescope
for the Pulkova Observatory in Russia, the 36-inch telescope of the
Lick Observatory in California, and, finally, the 40-inch of the
Yerkes Observatory in Chicago, were the outcome of the movement.

Of most interest to us in the present connection is the history
of the 30-inch telescope of the Pulkova Observatory, the object
glass of which was made by Alvan Clark & Sons.  It was, I think,
sometime in 1878 that I received a letter from Otto Struve, [2]
director of the Pulkova Observatory, stating that he was arranging
with his government for a grant of money to build one of the largest
refracting telescopes.  In answering him I called his attention to
the ability of Alvan Clark & Sons to make at least the object glass,
the most delicate and difficult part of the instrument.  The result
was that, after fruitless negotiations with European artists, Struve
himself came to America in the summer of 1879 to see what the American
firm could do.  He first went to Washington and carefully examined
the telescope there.  Then he proceeded to Cambridge and visited the
workshop of the Clarks.  He expressed some surprise at its modest
dimensions and fittings generally, but was so well pleased with what
he saw that he decided to award them the contract for making the
object glass.  He was the guest of the Pickerings at the Cambridge
Observatory, and invited me thither from where I was summering on
the coast of Massachusetts to assist in negotiating the contract.

He requested that, for simplicity in conference, the preliminary terms
should be made with but a single member of the firm to talk with.
George B. Clark, the eldest member, was sent up to represent the firm.
I was asked to take part in the negotiations as a mutual friend of
both parties, and suggested the main conditions of the contract.
A summary of these will be found in the publication to which I have
already referred.

There was one provision the outcome of which was characteristic
of Alvan Clark & Sons.  Struve, in testing some object glasses
which they had constructed and placed in their temporary tube,
found so great physical exertion necessary in pointing so rough
an instrument at any heavenly body with sufficient exactness,
that he could not form a satisfactory opinion of the object glass.
As he was to come over again when the glass was done, in order to
test it preliminary to acceptance, he was determined that no such
difficulty should arise.  He therefore made a special provision
that $1000 extra, to be repaid by him, should be expended in making
a rough equatorial mounting in which he could test the instrument.
George Clark demurred to this, on the ground that such a mounting as
was necessary for this purpose could not possibly cost so much money.
But Struve persistently maintained that one to cost $1000 should
be made.  The other party had to consent, but failed to carry out
this provision.  The tube was, indeed, made large enough to test not
only Struve's glass but the larger one of the Lick Observatory, which,
though not yet commenced, was expected to be ready not long afterward.
Yet, notwithstanding this increase of size, I think the extra cost
turned out to be much less than $1000, and the mounting was so rough
that when Struve came over in 1883 to test the glass, he suffered
much physical inconvenience and met, if my memory serves me aright,
with a slight accident, in his efforts to use the rough instrument.

In points like this I do not believe that another such business firm
as that of the Clarks ever existed in this country or any other.
Here is an example.  Shortly before the time of Struve's visit,
I had arranged with them for the construction of a refined and
complicated piece of apparatus to measure the velocity of light.
As this apparatus was quite new in nearly all its details, it was
impossible to estimate in advance what it might cost; so, of course,
they desired that payment for it should be arranged on actual cost
after the work was done.  I assured them that the government would
not enter into a contract on such terms.  There must be some maximum
or fixed price.  This they fixed at $2500.  I then arranged with
them that this should be taken as a maximum and that, if it was
found to cost less, they should accept actual cost.  The contract
was arranged on this basis.  There were several extras, including
two most delicate reflecting mirrors which would look flat to the
eye, but were surfaces of a sphere of perhaps four miles diameter.
The entire cost of the apparatus, as figured up by them after it was
done, with these additions, was less than $1500, or about forty per
cent. below the contract limit.

No set of men were ever so averse to advertising themselves.
If anybody, in any part of the world, wanted them to make a telescope,
he must write to them to know the price, etc.  They could never be
induced to prepare anything in the form of a price catalogue of the
instruments they were prepared to furnish.  The history of their
early efforts and the indifference of our scientific public to their
skill forms a mortifying chapter in our history of the middle of the
century.  When Mr. Clark had finished his first telescope, a small
one of four inches aperture, which was, I have no reason to doubt,
the best that human art could make, he took it to the Cambridge
Observatory to be tested by one of the astronomers.  The latter
called his attention to a little tail which the glass showed as
an appendage of a star, and which was, of course, non-existent.
It was attributed to a defect in the glass, which was therefore
considered a failure.  Mr. Clark was quite sure that the tail was
not shown when he had previously used the glass, but he could not
account for it at the time.  He afterwards traced it to the warm air
collecting in the upper part of the tube and producing an irregular
refraction of the light.  When this cause was corrected the defect
disappeared.  But he got no further encouragement at home to pursue
his work.  The first recognition of his genius came from England,
the agent being Rev. W. R. Dawes, an enthusiastic observer of double
stars, who was greatly interested in having the best of telescopes.
Mr. Clark wrote him a letter describing a number of objects which
he had seen with telescopes of his own make.  From this description
Mr. Dawes saw that the instruments must be of great excellence, and
the outcome of the matter was that he ordered one or more telescopes
from the American maker.  Not until then were the abilities of the
latter recognized in his own country.

I have often speculated as to what the result might have been had
Mr. Clark been a more enterprising man.  If, when he first found
himself able to make a large telescope, he had come to Washington,
got permission to mount his instrument in the grounds of the capitol,
showed it to members of Congress, and asked for legislation to
promote this new industry, and, when he got it, advertised himself
and his work in every way he could, would the firm which he founded
have been so little known after the death of its members, as it
now unhappily is?  This is, perhaps, a rather academic question,
yet not an unprofitable one to consider.

In recent years the firm was engaged only to make object glasses
of telescopes, because the only mountings they could be induced to
make were too rude to satisfy astronomers.  The palm in this branch
of the work went to the firm of Warner & Swasey, whose mounting of
the great Yerkes telescope of the University of Chicago is the last
word of art in this direction.

During the period when the reputation of the Cambridge family was
at its zenith, I was slow to believe that any other artist could
come up to their standard.  My impression was strengthened by a
curious circumstance.  During a visit to the Strasburg Observatory
in 1883 I was given permission to look through its great telescope,
which was made by a renowned German artist.  I was surprised to find
the object glass affected by so serious a defect that it could not be
expected to do any work of the first class.  One could only wonder
that European art was so backward.  But, several years afterward,
the astronomers discovered that, in putting the glasses together after
being cleaned, somebody had placed one of them in the wrong position,
the surface which should have been turned toward the star being now
turned toward the observer.  When the glass was simply turned over
so as to have the right face outward, the defect disappeared.

[1] In justice to Mr. Blank, I must say that there seems to have been
some misunderstanding as to his observations.  What he had really
seen and observed was a star long well known, much more distant from
Procyon than the companion in question.

[2] Otto Struve was a brother of the very popular Russian minister to
Washington during the years 1882-92.  He retired from the direction
of the Pulkowa Observatory about 1894.  The official history of
his negotiations and other proceedings for the construction of the
telescope will be found in a work published in 1889 in honor of the
jubilee of the observatory.




VI

THE TRANSITS OF VENUS


It was long supposed that transits of Venus over the sun's disk
afforded the only accurate method of determining the distance of the
sun, one of the fundamental data of astronomy.  Unfortunately, these
phenomena are of the rarest.  They come in pairs, with an interval
of eight years between the transits of a pair.  A pair occurred
in 1761 and 1769, and again in 1874 and 1882.  Now the whole of
the twentieth century will pass without another recurrence of the
phenomenon.  Not until the years 2004 and 2012 will our posterity
have the opportunity of witnessing it.

Much interesting history is associated with the adventures of the
astronomers who took part in the expeditions to observe the transits
of 1761 and 1769.  In the almost chronic warfare which used to rage
between France and England during that period, neither side was
willing to regard as neutral even a scientific expedition sent out
by the other.  The French sent one of their astronomers, Le Gentil,
to observe the transit at Pondicherry in the East Indies.  As he
was nearing his station, the presence of the enemy prevented him
from making port, and he was still at sea on the day of the transit.
When he at length landed, he determined to remain until the transit
of 1769, and observe that.  We must not suppose, however, that he
was guilty of the eccentricity of doing this with no other object in
view than that of making the observation.  He found the field open
for profitable mercantile enterprise, as well as interesting for
scientific observations and inquiries.  The eight long years passed
away, and the morning of June 4, 1769, found him in readiness for
his work.  The season had been exceptionally fine.  On the morning
of the transit the sun shone in a cloudless sky, as it had done for
several days previous.  But, alas for all human hopes!  Just before
Venus reached the sun, the clouds gathered, and a storm burst upon
the place.  It lasted until the transit was over, and then cleared
away again as if with the express object of showing the unfortunate
astronomer how helpless he was in the hands of the elements.

The Royal Society of England procured a grant of £800 from King
George II. for expeditions to observe the transit of 1761. [1]
With this grant the Society sent the Rev. Nevil Maskelyne to the
island of St. Helena, and, receiving another grant, it was used to
dispatch Messrs. Mason and Dixon (those of our celebrated "line")
to Bencoolen.  The admiralty also supplied a ship for conveying the
observers to their respective destinations.  Maskelyne, however,
would not avail himself of this conveyance, but made his voyage
on a private vessel.  Cloudy weather prevented his observations of
the transit, but this did not prevent his expedition from leaving
for posterity an interesting statement of the necessaries of an
astronomer of that time.  His itemized account of personal expenses
was as follows:--

 One year's board at St. Helena .   .  £109  10s.  0d.
 Liquors at 5s. per day .   .   .   .    91   5    0
 Washing at 9d. per day .   .   .   .    13  13    9
 Other expenses .   .   .   .   .   .    27   7    6
 Liquors on board ship for six months    50   0    0
                                        ---  ---  ---
                                       £291  16s.  3d.

Seven hundred dollars was the total cost of liquors during the
eighteen months of his absence.  Admiral Smyth concludes that
Maskelyne "was not quite what is now ycleped a teetotaler."  He was
subsequently Astronomer Royal of England for nearly half a century,
but his published observations give no indication of the cost of
the drinks necessary to their production.

Mason and Dixon's expedition met with a mishap at the start.
They had only got fairly into the English Channel when their ship
fell in with a French frigate of superior force.  An action ensued in
which the English crew lost eleven killed and thirty-eight wounded.
The Frenchman was driven off, but the victorious vessel had to return
to Plymouth for repairs.  This kind of a scientific expedition was
more than the astronomers had bargained for, and they wrote from
Plymouth to the Royal Society, describing their misfortune and
resigning their mission.  But the Council of the Society speedily
let them know that they were unmoved by the misfortunes of their
scientific missionaries, and pointed out to them in caustic terms
that, having solemnly undertaken the expedition, and received money
on account of it, their failure to proceed on the voyage would
be a reproach to the nation in general, and to the Royal Society
in particular.  It would also bring an indelible scandal upon their
character, and probably end in their utter ruin.  They were assured
that if they persisted in the refusal, they would be treated with the
most inflexible resentment, and prosecuted with the utmost severity
of the law.

Under such threats the unfortunate men could do nothing but accept
the situation and sail again after their frigate had been refitted.
When they got as far as the Cape of Good Hope, it was found very
doubtful whether they would reach their destination in time for
the transit; so, to make sure of some result from their mission,
they made their observations at the Cape.

One of the interesting scraps of history connected with the transit
of 1769 concerns the observations of Father Maximilian Hell, S. J.,
the leading astronomer of Vienna.  He observed the transit at Wardhus,
a point near the northern extremity of Norway, where the sun did not
set at the season of the transit.  Owing to the peculiar circumstances
under which the transit was observed,--the ingress of the planet
occurring two or three hours before the sun approached the northern
horizon, and the end of the transit about as long afterward,--this
station was the most favorable one on the globe.  Hell, with two or
three companions, one of them named Sajnovics, went on his mission
to this isolated place under the auspices of the king of Denmark.
The day was cloudless and the observations were made with entire
success.  He returned to Copenhagen, where he passed several months
in preparing for the press a complete account of his expedition and
the astronomical observations made at the station.

Astronomers were impatient to have the results for the distance of
the sun worked out as soon as possible.  Owing to the importance of
Hell's observations, they were eagerly looked for.  But he at first
refused to make them known, on the ground that, having been made
under the auspices of the king of Denmark, they ought not to be made
known in advance of their official publication by the Danish Academy
of Sciences.  This reason, however, did not commend itself to the
impatient astronomers; and suspicions were aroused that something
besides official formalities was behind the delay.  It was hinted
that Hell was waiting for the observations made at other stations in
order that he might so manipulate his own that they would fit in with
those made elsewhere.  Reports were even circulated that he had not
seen the transit at all, owing to cloudy weather, and that he was
manufacturing observations in Copenhagen.  The book was, however,
sent to the printer quite promptly, and the insinuations against its
author remained a mere suspicion for more than sixty years.  Then,
about 1833, a little book was published on the subject by Littrow,
Director of the Vienna Observatory, which excited much attention.
Father Hell's original journal had been conveyed to Vienna on his
return, and was still on deposit at the Austrian National Observatory.
Littrow examined it and found, as he supposed, that the suspicions
of alterations in observations were well founded; more especially
that the originals of the all-important figures which recorded the
critical moment of "contact" had been scraped out of the paper,
and new ones inserted in their places.  The same was said to be
the case with many other important observations in the journal, and
the conclusion to which his seemingly careful examination led was
that no reliance could be placed on the genuineness of Hell's work.
The doubts thus raised were not dispelled until another half-century
had elapsed.

In 1883 I paid a visit to Vienna for the purpose of examining the
great telescope which had just been mounted in the observatory there
by Grubb, of Dublin.  The weather was so unfavorable that it was
necessary to remain two weeks, waiting for an opportunity to see
the stars.  One evening I visited the theatre to see Edwin Booth,
in his celebrated tour over the Continent, play King Lear to the
applauding Viennese.  But evening amusements cannot be utilized to
kill time during the day.  Among the tasks I had projected was that
of rediscussing all the observations made on the transits of Venus
which had occurred in 1761 and 1769, by the light of modern science.
As I have already remarked, Hell's observations were among the most
important made, if they were only genuine.  So, during my almost
daily visits to the observatory, I asked permission of Director
Weiss to study Hell's manuscript.

At first the task of discovering anything which would lead to a
positive decision on one side or the other seemed hopeless.  To a
cursory glance, the descriptions given by Littrow seemed to cover the
ground so completely that no future student could turn his doubt into
certainty.  But when one looks leisurely at an interesting object,
day after day, he continually sees more and more.  Thus it was in
the present case.  One of the first things to strike me as curious
was that many of the alleged alterations had been made before the
ink got dry.  When the writer made a mistake, he had rubbed it out
with his finger, and made a new entry.

The all-important point was a certain suspicious record which Littrow
affirmed had been scraped out so that the new insertion could
be made.  As I studied these doubtful figures, day by day, light
continually increased.  Evidently the heavily written figures, which
were legible, had been written over some other figures which were
concealed beneath them, and were, of course, completely illegible,
though portions of them protruded here and there outside of the
heavy figures.  Then I began to doubt whether the paper had been
scraped at all.  To settle the question, I found a darkened room,
into which the sun's rays could be admitted through an opening in the
shutter, and held the paper in the sunlight in such a way that the
only light which fell on it barely grazed the surface of the paper.
Examining the sheet with a magnifying glass, I was able to see the
original texture of the surface with all its hills and hollows.
A single glance sufficed to show conclusively that no eraser had
ever passed over the surface, which had remained untouched.

The true state of the case seemed to me almost beyond doubt.
It frequently happened that the ink did not run freely from the
pen, so that the words had sometimes to be written over again.
When Hell first wrote down the little figures on which, as he
might well suppose, future generations would have to base a very
important astronomical element, he saw that they were not written
with a distinctness corresponding to their importance.  So he wrote
them over again with the hand, and in the spirit of a man who was
determined to leave no doubt on the subject, little weening that
the act would give rise to a doubt which would endure for a century.

This, although the most important case of supposed alteration, was by
no means the only one.  Yet, to my eyes, all the seeming corrections
in the journal were of the most innocent and commonplace kind,--such
as any one may make in writing.

Then I began to compare the manuscript, page after page, with
Littrow's printed description.  It struck me as very curious that
where the manuscript had been merely retouched with ink which was
obviously the same as that used in the original writing, but looked
a little darker than the original, Littrow described the ink as of
a different color.  In contrast with this, there was an important
interlineation, which was evidently made with a different kind of
ink, one that had almost a blue tinge by comparison; but in the
description he makes no mention of this plain difference.  I thought
this so curious that I wrote in my notes as follows:--

"That Littrow, in arraying his proofs of Hell's forgery, should
have failed to dwell upon the obvious difference between this ink
and that with which the alterations were made leads me to suspect
a defect in his sense of color."

Then it occurred to me to inquire whether, perhaps, such could have
been the case.  So I asked Director Weiss whether anything was known
as to the normal character of Littrow's power of distinguishing
colors.  His answer was prompt and decisive.  "Oh, yes, Littrow was
color blind to red.  He could not distinguish between the color of
Aldebaran and that of the whitest star."  No further research was
necessary.  For half a century the astronomical world had based an
impression on the innocent but mistaken evidence of a color-blind
man respecting the tints of ink in a manuscript.

About the middle of the nineteenth century other methods of measuring
the sun's distance began to be developed which, it was quite possible,
might prove as good as the observation in question.  But the relative
value of these methods and of transits of Venus was a subject on which
little light could be thrown; and the rarity of the latter phenomena
naturally excited universal interest, both among the astronomers
and among the public.  For the purpose in question it was necessary
to send expeditions to different and distant parts of the globe,
because the result had to depend upon the times of the phases,
as seen from widely separated stations.

In 1869 the question what stations should be occupied and what
observations should be made was becoming the subject of discussion
in Europe, and especially in England.  But our country was still
silent on the subject.  The result of continued silence was not hard
to foresee.  Congress would, at the last moment, make a munificent
appropriation for sending out parties to observe the transit.
The plans and instruments would be made in a hurry, and the parties
packed off without any well-considered ideas of what they were to
do; and the whole thing would end in failure so far as results of
any great scientific value were concerned.

I commenced the discussion by a little paper on the subject in the
"American Journal of Science," but there was no one to follow it up.
So, at the spring meeting of the National Academy of Sciences, in
1870, I introduced a resolution for the appointment of a committee to
consider the subject and report upon the observations which should
be made.  This resolution was adopted, and a few days afterward
Professor Henry invited me to call at his office in the evening to
discuss with himself and Professor Peirce, then superintendent of
the Coast Survey, the composition of the committee.

At the conference I began by suggesting Professor Peirce himself
for chairman.  Naturally this met with no opposition; then I waited
for the others to go on.  But they seemed determined to throw the
whole onus of the matter on me.  This was the more embarrassing,
because I believe that, in parliamentary law and custom, the mover
of a resolution of this sort has a prescribed right to be chairman
of the committee which he proposes shall be appointed.  If not
chairman, it would seem that he ought at any rate to be a member.
But I was determined not to suggest myself in any way, so I went on
and suggested Admiral Davis.  This nomination was, of course, accepted
without hesitation.  Then I remarked that the statutes of the academy
permitted of persons who were not members being invited to serve on a
committee, and as the Naval Observatory would naturally take a leading
part in such observations as were to be made, I suggested that its
superintendent, Admiral Sands, should be invited to serve as a member
of the committee.  "There," said Peirce, "we now have three names.
Committees of three are always the most efficient.  Why go farther?"

I suggested that the committee should have on it some one practiced
in astronomical observation, but he deemed this entirely unnecessary,
and so the committee of three was formed.  I did not deem it advisable
to make any opposition at the time, because it was easy to foresee
what the result would be.

During the summer nothing was heard of the committee, and in the
autumn I made my first trip to Europe.  On my return, in May, 1871,
I found that the committee had never even held a meeting, and that
it had been enlarged by the addition of a number of astronomers,
among them myself.  But, before it went seriously to work, it was
superseded by another organization, to be described presently.

At that time astronomical photography was in its infancy.  Enough had
been done by Rutherfurd to show that it might be made a valuable
adjunct to astronomical investigation.  Might we not then photograph
Venus on the sun's disk, and by measurements of the plates obtain the
desired result, perhaps better than it could be obtained by any kind
of eye observation?  This question had already suggested itself to
Professor Winlock, who, at the Cambridge Observatory, had designed
an instrument for taking the photographs.  It consisted of a fixed
horizontal telescope, into which the rays of the sun were to be
thrown by a reflector.  This kind of an instrument had its origin
in France, but it was first practically applied to photographing
the sun in this country.  As whatever observations were to be made
would have to be done at governmental expense, an appropriation of
two thousand dollars was obtained from Congress for the expense of
some preliminary instruments and investigations.

Admiral Sands, superintendent of the observatory, now took an
active part in the official preparations.  It was suggested to
him, on the part of the academy committee, that it would be well
to join hands with other organizations, so as to have the whole
affair carried on with unity and harmony.  To this he assented.
The result was a provision that these and all other preparations for
observing the transit of Venus should be made under the direction
of a commission to be composed of the superintendent of the Naval
Observatory, the superintendent of the United States Coast Survey, the
president of the National Academy of Sciences, and two professors of
mathematics attached to the Naval Observatory.  Under this provision
the commission was constituted as follows: Commodore B. F. Sands,
U. S. N., Professor Benjamin Peirce, Professor Joseph Henry, Professor
Simon Newcomb, Professor William Harkness.

The academy committee now surrendered its functions to the commission,
and the preparations were left entirely in the hands of the latter.

So far as scientific operations were concerned, the views of the
commission were harmonious through the whole of their deliberations.
It was agreed from the beginning that the photographic method
offered the greatest promise of success.  But how, with what sort
of instruments, and on what plan, must the photographs be taken?
Europeans had already begun to consider this question, and for the
most part had decided on using photographic telescopes having no
distinctive feature specially designed for the transit.  In fact,
one might almost say that the usual observations with the eye
were to be made on the photograph instead of on the actual sun.
The American commissioners were of opinion that this would lead to
nothing but failure, and that some new system must be devised.

The result was a series of experiments and trials with Professor
Winlock's instrument at the Cambridge Observatory.  The outcome of
the matter was the adoption of his plan, with three most important
additions, which I shall mention, because they may possibly yet be
adopted with success in other branches of exact astronomy if this
telescope is used, as it seems likely it may be.

The first feature was that the photographic telescope should be
mounted exactly in the meridian, and that its direction should be
tested by having the transit instrument mounted in front of it,
in the same line with it.  In this way the axis of the telescope
was a horizontal north and south line.

The next feature was that, immediately in front of the photographic
plate, in fact as nearly in contact with it as possible without
touching it, a plumb line of which the thread was a very fine silver
wire should be suspended, the bob of which passed down below, and
was immersed in a vessel of water to prevent vibration.  In this way
the direction of the north and south line on the plate admitted of
being calculated with the greatest exactness, and the plumb line being
photographed across the disk of the sun, the position angle could be
measured with the same precision that any other measure could be made.

The third feature was that the distance between the photographic
plate and the object glass of the telescope should be measured by
a long iron rod which was kept in position above the line of sight
of the telescope itself.  This afforded the means of determining
to what angle a given measure on the plate would correspond.
The whole arrangement would enable the position of the centre of
Venus with respect to the centre of the sun to be determined by
purely geometric methods.  One reason for relying entirely on this
was that the diameter of the sun, as photographed, would be greater
the greater the intensity of the photographic impression, so that
no reliance could be placed upon its uniformity.

Ours were the only parties whose photographic apparatus was fitted
up in this way.  The French used a similar system, but without the
essentials of the plumb line and the measurement of the length of
the telescope.  The English and Germans used ordinary telescopes
for the purpose.

One of the earliest works of the commission was the preparation
and publication of several papers, which were published under the
general title, "Papers relating to the Transit of Venus in 1874."
The first of these papers was a discussion of our proposed plan of
photographing, in which the difficulties of the problem, and the
best way of surmounting them, were set forth.  The next, called
Part II., related to the circumstances of the transit, and was
therefore entirely technical.  Part III. related to the corrections
of Hansen's table of the moon, and was published as a paper relating
to the transit of Venus, because these corrections were essential
in determining the longitudes of the stations by observations of
the moon.

In England the preparations were left mostly in the hands of
Professor Airy, Astronomer Royal, and, I believe, Captain Tupman,
who at least took a leading part in the observations and their
subsequent reduction.  In France, Germany, and Russia, commissions
were appointed to take charge of the work and plan the observations.

As coöperation among the parties from different countries would be
generally helpful, I accepted an invitation to attend a meeting of the
German commission, to be held at Hanover in August, 1873.  Hansen was
president of the commission, while Auwers was its executive officer.
One of my main objects was to point out the impossibility of obtaining
any valuable result by the system of photographing which had been
proposed, but I was informed, in reply, that the preparations had
advanced too far to admit of starting on a new plan and putting it
in operation.

From the beginning of our preparations it began to be a question
of getting from Congress the large appropriations necessary for
sending out the expeditions and fitting them up with instruments.
The sum of $50,000 was wanted for instruments and outfit.  Hon. James
A. Garfield was then chairman of the committee on appropriations.
His principles and methods of arranging appropriations for the
government were, in some features, so different from those generally
in vogue that it will be of interest to describe them.

First of all, Garfield was rigidly economical in grants of money.
This characteristic of a chairman of a committee on appropriations
was almost a necessary one.  But he possessed it in a different
way from any other chairman before or since.  The method of the
"watch dogs of the treasury" who sometimes held this position was to
grant most of the objects asked for, but to cut down the estimated
amounts by one fourth or one third.  This was a very easy method,
and one well fitted to impress the public, but it was one that the
executive officers of the government found no difficulty in evading,
by the very simple process of increasing their estimate so as to
allow for the prospective reduction. [2]

Garfield compared this system to ordering cloth for a coat,
but economizing by reducing the quantity put into it.  If a new
proposition came before him, the question was whether it was advisable
for the government to entertain it at all.  He had to be thoroughly
convinced before this would be done.  If the question was decided
favorably all the funds necessary for the project were voted.

When the proposition for the transit of Venus came before him,
he proceeded in a manner which I never heard of the chairman of an
appropriation committee adopting before or since.  Instead of calling
upon those who made the proposition to appear formally before the
committee, he asked me to dinner with his family, where we could
talk the matter over.  One other guest was present, Judge Black
of Pennsylvania.  He was a dyed-in-the-wool Democrat, wielding
as caustic a pen as was ever dipped into ink, but was, withal,
a firm personal friend and admirer of Garfield.  As may readily be
supposed, the transit of Venus did not occupy much time at the table.
I should not have been an enthusiastic advocate of the case against
opposition, in any case, because my hopes of measuring the sun's
distance satisfactorily by that method were not at all sanguine.
My main interest lay in the fact that, apart from this, the transit
would afford valuable astronomical data for the life work which I
had mainly in view.  So the main basis of my argument was that other
nations were going to send out parties; that we should undoubtedly
do the same, and that they must be equipped and organized in the
best way.

It appears that Judge Black was an absent-minded man, as any man
engaged in thought on very great subjects, whether of science,
jurisprudence, or politics, has the right to be.  Garfield asked him
whether it was true that, on one occasion, when preparing an argument,
and walking up and down the room, his hat chanced to drop on the floor
at one end of the room, and was persistently used as a cuspidor until
the argument was completed.  Mr. Black neither affirmed nor denied
the story, but told another which he said was true.  While on his
circuit as judge he had, on one occasion, tried a case of theft in
which the principal evidence against the accused was the finding of
the stolen article in his possession.  He charged the jury that this
fact was _prima facie_ evidence that the man was actually the thief.
When through his business and about to leave for home, he went
into a jeweler's shop to purchase some little trinket for his wife.
The jeweler showed him a number of little articles, but finding none
to suit him, he stepped into his carriage and drove off.  In the
course of the day he called on a street urchin to water his horse.
Reaching into his pocket for a reward, the first thing he got hold of
was a diamond ring which must have been taken from the shop of the
jeweler when he left that morning.  "I wondered," said the judge,
"how I should have come out had I been tried under my own law."

The outcome of the matter was that the appropriations were duly made;
first, in 1872, $50,000 for instruments, then, the year following,
$100,000 for the expeditions.  In 1874, $25,000 more was appropriated
to complete the work and return the parties to their homes.

The date of the great event was December 8-9, 1874.  To have the
parties thoroughly drilled in their work, they were brought together
at Washington in the preceding spring for practice and rehearsal.
In order that the observations to be made by the eye should not
be wholly new, an apparatus representing the transit was mounted
on the top of Winder's building, near the War Department, about
two thirds of a mile from the observatory.  When this was observed
through the telescope from the roof of the observatory, an artificial
black Venus was seen impinging upon an artificial sun, and entering
upon its disk in the same way that the actual Venus would be seen.
This was observed over and over until, as was supposed, the observers
had gotten into good practice.

In order to insure the full understanding of the photographic
apparatus, the instruments were mounted and the parties practiced
setting them up and going through the processes of photographing the
sun.  To carry out this arrangement with success, it was advisable to
have an expert in astronomical photography to take charge of the work.
Dr. Henry Draper of New York was invited for this purpose, and gave
his services to the commission for several weeks.

This transit was not visible in the United States.  It did not begin
until after the sun had set in San Francisco, and it was over before
the rising sun next morning had reached western Europe.  All the
parties had therefore to be sent to the other side of the globe.
Three northern stations were occupied,--in China, Japan, and Siberia;
and five southern ones, at various points on the islands of the
Pacific and Indian oceans.  This unequal division was suggested
by the fact that the chances of fair weather were much less in the
southern hemisphere than in the northern.

The southern parties were taken to their destinations in the
U. S. S. Swatara, Captain Ralph Chandler, U. S. N., commanding.
In astronomical observations all work is at the mercy of the elements.
Clear weather was, of course, a necessity to success at any station.
In the present case the weather was on the whole unpropitious.
While there was not a complete failure at any one station, the number
or value of the observations was more or less impaired at all.
Where the sky was nearly cloudless, the air was thick and hazy.
This was especially the case at Nagasaki and Pekin, where from
meteorological observations which the commission had collected through
our consuls, the best of weather was confidently expected.  What made
this result more tantalizing was that the very pains we had taken to
collect the data proved, by chance, to have made the choice worse.
For some time it was deliberated whether the Japanese station should
be in Nagasaki or Yokohama.  Consultation with the best authorities
and a study of the records showed that, while Yokohama was a favorable
spot, the chances were somewhat better at Nagasaki.  So to Nagasaki
the party was sent.  But when the transit came, while the sky was
of the best at Yokohama, it was far from being so at Nagasaki.

Something of the same sort occurred at the most stormy of all the
southern stations, that at Kerguelen Island.  The British expeditions
had, in the beginning, selected a station on this island known as
Christmas Harbor.  We learned that a firm of New London, Conn.,
had a whaling station on the island.  It was therefore applied to to
know what the weather chances were at various points in the island.
Information was obtained from their men, and it was thus found that
Molloy Point, bad though the weather there was, afforded better
chances than Christmas Harbor; so it was chosen.  But this was not
all; the British parties, either in consequence of the information
we had acquired, or through what was learned from the voyage of the
Challenger, established their principal station near ours.  But it
happened that the day at Christmas Harbor was excellent, while
the observations were greatly interfered with by passing clouds at
Molloy Point.

After the return of the parties sent out by the various nations,
it did not take long for the astronomers to find that the result was
disappointing, so far, at least, as the determination of the sun's
distance was concerned.  It became quite clear that this important
element could be better measured by determining the velocity of
light and the time which it took to reach us from the sun than it
could by any transit of Venus.  It was therefore a question whether
parties should be sent out to observe the transit of 1882.  On this
subject the astronomers of the country at large were consulted.
As might have been expected, there was a large majority in favor
of the proposition.  The negative voices were only two in number,
those of Pickering and myself.  I took the ground that we should
make ample provisions for observing it at various stations in
our own country, where it would now be visible, but that, in view
of the certain failure to get a valuable result for the distance
of the sun by this method, it was not worth while for us to send
parties to distant parts of the world.  I supposed the committee on
appropriations might make careful inquiry into the subject before
making the appropriation, but a representation of the case was all
they asked for, and $10,000 was voted for improving the instruments
and $75,000 for sending out parties.

Expeditions being thus decided upon, I volunteered to take charge of
that to the Cape of Good Hope.  The scientific personnel of my party
comprised an officer of the army engineers, one of the navy, and a
photographer.  The former were Lieutenant Thomas L. Casey, Jr., Corps
of Engineers, U. S. A., and Lieutenant J. H. L. Holcombe, U. S. N.
We took a Cunard steamer for Liverpool about the middle of September,
1882, and transported our instruments by rail to Southampton, there
to have them put on the Cape steamship.  At Liverpool I was guilty
of a remissness which might have caused much trouble.  Our apparatus
and supplies, in a large number of boxes, were all gathered and
piled in one place.  I sent one of my assistants to the point to
see that it was so collected that there should be no possibility
of mistake in getting it into the freight car designed to carry it
to Southampton, but did not require him to stay there and see that
all was put on board.  When the cases reached Southampton it was
found that one was missing.  It was one of the heaviest of the lot,
containing the cast-iron pier on which the photoheliograph was to
be mounted.  While it was possible to replace this by something else,
such a course would have been inconvenient and perhaps prejudicial.
The steamer was about to sail, but would touch at Plymouth next day.
Only one resource was possible.  I telegraphed the mistake to
Liverpool and asked that the missing box be sent immediately by
express to Plymouth.  We had the satisfaction of seeing it come on
board with the mail just as the steamer was about to set sail.

We touched first at Madeira, and then at Ascension Island, the latter
during the night.  One of the odd things in nomenclature is that this
island, a British naval station, was not called such officially,
but was a "tender to Her Majesty's ship Flora," I believe.  It had
become astronomically famous a few years before by Gill's observations
of the position of Mars to determine the solar parallax.

We touched six hours at St. Helena, enough to see the place, but
scarcely enough to make a visit to the residence of Napoleon, even had
we desired to see it.  The little town is beautifully situated, and
the rocks around are very imposing.  My most vivid recollection is,
however, of running down from the top of a rock some six hundred or
eight hundred feet high, by a steep flight of steps, without stopping,
or rather of the consequences of this imprudent gymnastic performance.
I could scarcely move for the next three days.

Cape Town was then suffering from an epidemic of smallpox, mostly
confined to the Malay population, but causing some disagreeable
results to travelers.  Our line of ships did not terminate their
voyage at the Cape, but proceeded thence to other African ports east
of the Cape.  Here a rigid quarantine had been established, and it
was necessary that the ships touching at the Cape of Good Hope should
have had no communication with the shore.  Thus it happened that we
found, lying in the harbor, the ship of our line which had preceded
us, waiting to get supplies from us, in order that it might proceed
on its voyage.  Looking at a row-boat after we had cast anchor, we
were delighted to see two faces which I well knew: those of David
Gill, astronomer of the Cape Observatory, and Dr. W. L. Elkin, now
director of the Yale Observatory.  The latter had gone to the Cape as
a volunteer observer with Gill, their work being directed mostly to
parallaxes of stars too far south to be well observed in our latitude.
Our friends were not, however, even allowed to approach the ship,
for fear of the smallpox, the idea appearing to be that the latter
might be communicated by a sort of electric conduction, if the boat
and the ship were allowed to come into contact, so we had to be put
ashore without their aid.

We selected as our station the little town of Wellington, some forty
miles northeast of Cape Town.  The weather chances were excellent
anywhere, but here they were even better than at the Cape.  The most
interesting feature of the place was what we might call an American
young ladies' school.  The Dutch inhabitants of South Africa are
imbued with admiration of our institutions, and one of their dreams
is said to be a United States of South Africa modeled after our
own republic.  Desiring to give their daughters the best education
possible, they secured the services of Miss Ferguson, a well-known
New England teacher, to found a school on the American model.
We established our station in the grounds of this school.

The sky on the day of the transit was simply perfect.  Notwithstanding
the intensity of the sun's rays, the atmosphere was so steady that I
have never seen the sun to better advantage.  So all our observations
were successful.

On our departure we left two iron pillars, on which our apparatus for
photographing the sun was mounted, firmly imbedded in the ground, as
we had used them.  Whether they will remain there until the transit
of 2004, I do not know, but cannot help entertaining a sentimental
wish that, when the time of that transit arrives, the phenomenon
will be observed from the same station, and the pillars be found in
such a condition that they can again be used.

All the governments, except our own, which observed the two transits
of Venus on a large scale long ago completed the work of reduction,
and published the observations in full.  On our own part we have
published a preliminary discussion of some observations of the transit
of 1874.  Of that of 1882 nothing has, I believe, been published
except some brief statements of results of the photographs, which
appeared in an annual report of the Naval Observatory.  Having need in
my tables of the planets of the best value of the solar parallax that
could be obtained by every method, I worked up all the observations
of contacts made by the parties of every country, but, of course,
did not publish our own observations.  Up to the present time,
twenty-eight years after the first of the transits, and twenty
years after the second, our observations have never been officially
published except to the extent I have stated.  The importance of
the matter may be judged by the fact that the government expended
$375,000 on these observations, not counting the salaries of its
officers engaged in the work, or the cost of sailing a naval ship.
As I was a member of the commission charged with the work, and must
therefore bear my full share of the responsibility for this failure,
I think it proper to state briefly how it happened, hoping thereby
to enforce the urgent need of a better organization of some of our
scientific work.

The work of reducing such observations, editing and preparing them for
the press, involved much computation to be done by assistants, and I,
being secretary of the commission, was charged with the execution
of this part of the work.  The appropriations made by Congress for
the observations were considered available for the reduction also.
There was a small balance left over, and I estimated that $3000 more
would suffice to complete the work.  This was obtained from Congress
in the winter of 1875.

About the end of 1876 I was surprised to receive from the Treasury
Department a notification that the appropriation for the transit
of Venus was almost exhausted, when according to my accounts, more
than $3000 still remained.  On inquiry it was found that the sum
appropriated about two years before had never been placed to the
credit of the transit of Venus commission, having been, in fact,
inserted in a different appropriation bill from that which contained
the former grant.

I, as secretary of the commission, made an application to the Treasury
Department to have the sum, late though it was, placed to our credit.
But the money had been expended and nothing could be now done in the
matter. [3]  The computers had therefore to be discharged and the work
stopped until a new appropriation could be obtained from Congress.

During the session of 1876-77, $5000 was therefore asked for for
the reduction of the observations.  It was refused by the House
committee on appropriations.  I explained the matter to Mr. Julius
H. Seelye, formerly president of Amherst College, who was serving a
term in Congress.  He took much interest in the subject, and moved
the insertion of the item when the appropriation bill came up before
the House.  Mr. Atkins, chairman of the appropriations committee,
opposed the motion, maintaining that the Navy Department had under
its orders plenty of officers who could do the work, so there was
no need of employing the help of computers.  But the House took
a different view, and inserted the item over the heads of the
appropriations committee.

Now difficulties incident to the divided responsibility of the
commission were met with.  During the interim between the death of
Admiral Davis, in February, 1877, and the coming of Admiral John
Rodgers as his successor, a legal question arose as to the power
of the commission over its members.  The work had to stop until
it was settled, and I had to discharge my computers a second time.
After it was again started I discovered that I did not have complete
control of the funds appropriated for reducing the observations.
The result was that the computers had to be discharged and the work
stopped for the third time.  This occurred not long before I started
out to observe the transit in 1882.  For me the third hair was the
one that broke the camel's back.  I turned the papers and work over
to Professor Harkness, by whom the subject was continued until he
was made astronomical director of the Naval Observatory in 1894.

I do not know that the commission was ever formally dissolved.
Practically, however, its functions may be said to have terminated
in the year 1886, when a provision of law was enacted by which all
its property was turned over to the Secretary of the Navy.

What the present condition of the work may be, and how much of it
is ready for the press, I cannot say.  My impression is that it
is in that condition known in household language as "all done but
finishing."  Whether it will ever appear is a question for the future.
All the men who took part in it or who understood its details are
either dead or on the retired list, and it is difficult for one not
familiar with it from the beginning to carry it to completion.

[1] For the incidents connected with the English observations of
this transit, the author is indebted to Vice-Admiral W. H. Smyth's
curious and rare book, _Speculum Hartwellianum_, London, 1860.
It and other works of the same author may be described as queer and
interesting jumbles of astronomical and other information, thrown
into an interesting form; and, in the case of the present work,
spread through a finely illustrated quarto volume of nearly five
hundred pages.

[2] "The War Department got ahead of us in the matter of furniture,"
said an officer of the Navy Department to me long afterwards, when
the furniture for the new department building was being obtained.
"They knew enough to ask for a third more than they wanted; we reduced
our estimate to the lowest point.  Both estimates were reduced one
third by the Appropriations Committee.  The result is that they have
all the furniture they want, while we are greatly pinched."

[3] As this result would not be possible under our present system,
which was introduced by the first Cleveland administration, I might
remark that it resulted from a practice on the part of the Treasury
of lumping appropriations on its books in order to simplify the
keeping of the accounts.




VII

THE LICK OBSERVATORY


In the wonderful development of astronomical research in our country
during the past twenty years, no feature is more remarkable than
the rise on an isolated mountain in California of an institution
which, within that brief period, has become one of the foremost
observatories of the world.  As everything connected with the early
history of such an institution must be of interest, it may not be
amiss if I devote a few pages to it.

In 1874 the announcement reached the public eye that James Lick, an
eccentric and wealthy Californian, had given his entire fortune to
a board of trustees to be used for certain public purposes, one of
which was the procuring of the greatest and most powerful telescope
that had ever been made.  There was nothing in the previous history
of the donor that could explain his interest in a great telescope.
I am sure he had never looked through a telescope in his life, and
that if he had, and had been acquainted with the difficulties of an
observation with it, it is quite likely the Lick Observatory would
never have existed.  From his point of view, as, indeed, from that of
the public very generally, the question of telescopic vision is merely
one of magnifying power.  By making an instrument large and powerful
enough we may hope even to discover rational beings on other planets.

The president of the first board of trustees was Mr. D. O. Mills,
the well-known capitalist, who had been president of the Bank of
California.  Mr. Mills visited Washington in the summer or autumn of
1874, and conferred with the astronomers there, among others myself,
on the question of the proposed telescope.  I do not think that an
observatory properly so called was, at first, in Mr. Lick's mind;
all he wanted was an immense telescope.

The question was complicated by the result of some correspondence
between Mr. Lick and the firm of Alvan Clark & Sons.  The latter
had been approached to know the cost of constructing the desired
telescope.  Without making any exact estimate, or deciding upon the
size of the greatest telescope that could be constructed, they named
a very large sum, $200,000 I believe, as the amount that could be
put into the largest telescope it was possible to make.  Mr. Lick
deemed this estimate exorbitant, and refused to have anything more
to do with the firm.  The question now was whether any one else
besides the Clarks could make what was wanted.

I suggested to Mr. Mills that this question was a difficult one to
answer, as no European maker was known to rival the Clerks in skill in
the desired direction.  It was impossible to learn what could be done
in Europe except by a personal visit to the great optical workshops
and a few observatories where great telescopes had been mounted.

I also suggested that a director of the new establishment should
be chosen in advance of beginning active work, so that everything
should be done under his supervision.  As such director I suggested
that very likely Professor Holden, then my assistant on the great
equatorial, might be well qualified.  At least I could not, at the
moment, name any one I thought would be decidedly preferable to him.
I suggested another man as possibly available, but remarked that
he had been unfortunate.  "I don't want to have anything to do
with unfortunate men," was the reply.  The necessity of choosing
a director was not, however, evident, but communication was opened
with Professor Holden as well as myself to an extent that I did not
become aware of until long afterward.

The outcome of Mr. Mills's visit was that in December, 1874, I was
invited to visit the European workshops as an agent of the Lick
trustees, with a view of determining whether there was any chance of
getting the telescope made abroad.  The most difficult and delicate
question arose in the beginning; shall the telescope be a reflector
or a refractor?  The largest and most powerful one that could be made
would be, undoubtedly, a reflector.  And yet reflecting telescopes
had not, as a rule, been successful in permanent practical work.
The world's work in astronomy was done mainly with refracting
telescopes.  This was not due to any inherent superiority in the
latter, but to the mechanical difficulties incident to so supporting
the great mirror of a reflecting telescope that it should retain its
figure in all positions.  Assuming that the choice must fall upon a
refractor, unless proper guarantees for one of the other kind should
be offered, one of my first visits was to the glass firm of Chance &
Co. in Birmingham, who had cast the glass disks for the Washington
telescope.  This firm and Feil of Paris were the only two successful
makers of great optical disks in the world.  Chance & Co. offered
the best guarantees, while Feil had more enthusiasm than capital,
although his skill was of the highest.  Another Paris firm was quite
willing to undertake the completion of the telescope, but it was also
evident that its price was suggested by the supposed liberality of an
eccentric California millionaire.  I returned their first proposal
with the assurance that it would be useless to submit it.  A second
was still too high to offer any inducement over the American firm.
Besides, there was no guarantee of the skill necessary to success.

In Germany the case was still worse.  The most renowned firm there,
the successors of Fraunhofer, were not anxious to undertake such
a contract.  The outcome of the matter was that Howard Grubb, of
Dublin, was the only man abroad with whom negotiations could be
opened with any chance of success.  He was evidently a genius who
meant business.  Yet he had not produced a work which would justify
unlimited confidence in his ability to meet Mr. Lick's requirements.
The great Vienna telescope which he afterward constructed was then
only being projected.

Not long after my return with this not very encouraging report,
Mr. Lick suddenly revoked his gift, through some dissatisfaction with
the proceedings of his trustees, and appointed a new board to carry
out his plans.  This introduced legal complications, which were soon
settled by a friendly suit on the part of the old trustees, asking
authority to transfer their trust.  The president of the new board was
Mr. Richard S. Floyd, a member of the well-known Virginia family of
that name, and a graduate, or at least a former cadet, of the United
States Naval Academy.  I received a visit from him on his first trip
to the East in his official capacity, early in 1876, I believe.  Some
correspondence with Mr. Lick's home representative ensued, of which
the most interesting feature was the donor's idea of a telescope.
He did not see why so elaborate and expensive a mounting as that
proposed was necessary, and thought that the object glass might be
mounted on the simplest kind of a pole or tower which would admit of
its having the requisite motions in connection with the eyepiece.
Whether I succeeded in convincing him of the impracticability of
his scheme, I do not know, as he died before the matter was settled.

This left the trustees at liberty to build and organize the
institution as they deemed best.  It was speedily determined that
the object glass should be shaped by the Clarks, who should also be
responsible for getting the rough disks.  This proved to be a very
difficult task.  Chance & Co. were unwilling to undertake the work and
Feil had gone out of business, leaving the manufacture in the hands
of his son.  The latter also failed, and the father had to return.
Ultimately the establishment was purchased by Mantois, whose success
was remarkable.  He soon showed himself able to make disks not only
of much larger size than had ever before been produced, but of a
purity and transparency which none before him had ever approached.
He died in 1899 or 1900, and it is to be hoped that his successor
will prove to be his equal.

The original plan of Mr. Lick had been to found the observatory
on the borders of Lake Tahoe, but he grew dissatisfied with this
site and, shortly before his death, made provisional arrangements
for placing it on Mount Hamilton.  In 1879 preparations had so far
advanced that it became necessary to decide whether this was really
a suitable location.  I had grave doubts on the subject.  A mountain
side is liable to be heated by the rays of the sun during the day,
and a current of warm air which would be fatal to the delicacy of
astronomical vision is liable to rise up the sides and envelope the
top of the mountain.  I had even been informed that, on a summer
evening, a piece of paper let loose on the mountain top would be
carried up into the air by the current.  But, after all, the proof of
the pudding is in the eating, and Holden united with me in advising
that an experienced astronomer with a telescope should be stationed
for a few weeks on the mountain in order to determine, by actual
trial, what the conditions of seeing were.  The one best man for
this duty was S. W. Burnham of Chicago, who had already attained
a high position in the astronomical world by the remarkable skill
shown in his observations of double stars.  So, in August, 1879,
huts were built on the mountain, and Burnham was transported thither
with his telescope.  I followed personally in September.

We passed three nights on the mountain with Captain Floyd, studying
the skies by night and prospecting around in the daytime to see
whether the mountain top or some point in the neighboring plateau
offered the best location for the observatory.  So far as the
atmospheric conditions were concerned, the results were beyond our
most sanguine expectations.  What the astronomer wants is not merely
a transparent atmosphere, but one of such steadiness that the image
of a star, as seen in a telescope, may not be disturbed by movements
of the air which are invisible to the naked eye.

Burnham found that there were forty-two first-class nights during his
stay, and only seven which would be classed as low as medium.  In the
East the number of nights which he would call first-class are but few
in a year, and even the medium night is by no means to be counted on.
No further doubt could remain that the top of the mountain was one
of the finest locations in the world for an astronomical observatory,
and it was definitely selected without further delay.

Sometime after my return Mr. Floyd sent me a topographical sketch
of the mountain, with a request to prepare preliminary plans for the
observatory.  As I had always looked on Professor Holden as probably
the coming director, I took him into consultation, and the plans
were made under our joint direction in my office.  The position and
general arrangement of the buildings remain, so far as I am aware,
much as then planned; the principal change being the omission of a
long colonnade extending over the whole length of the main front in
order to secure an artistic and imposing aspect from the direction
of San José.

In the summer of 1885, as I was in New York in order to sail
next day to Europe, I was surprised by a visit from Judge Hagar,
a prominent citizen of San Francisco, a member of the Board of
Regents of the University of California, and an active politician,
who soon afterward became collector of the port, to consult me on the
question of choosing Professor Holden as president of the university.
This was not to interfere with his becoming director of the Lick
Observatory whenever that institution should be organized, but was
simply a temporary arrangement to bridge over a difficulty.

In the autumn of 1887 I received an invitation from Mr. Floyd to go
with him to Cleveland, in order to inspect the telescope, which was
now nearly ready for delivery.  It was mounted in the year following,
and then Holden stepped from the presidency of the university into
the directorship of the observatory.

The institution made its mark almost from the beginning.  I know of no
example in the world in which young men, most of whom were beginners,
attained such success as did those whom Holden collected around him.
The names of Barnard, Campbell, and Schaeberle immediately became
well known in astronomy, owing to the excellence of their work.
Burnham was, of course, no beginner, being already well known,
nor was Keeler, who was also on the staff.

In a few years commenced the epoch-making work of Campbell, in the
most refined and difficult problem of observational astronomy,--that
of the measurement of the motion of stars to or from us.  Through the
application of photography and minute attention to details, this
work of the Lick Observatory almost immediately gained a position
of preëminence, which it maintains to the present time.  If any
rival is to appear, it will probably be the Yerkes Observatory.
The friendly competition which we are likely to see between these
two establishments affords an excellent example of the spirit of
the astronomy of the future.  Notwithstanding their rivalry, each
has done and will do all it can to promote the work of the other.

The smiles of fortune have been bestowed even upon efforts that seemed
most unpromising.  After work was well organized, Mr. Crossley,
of England, presented the observatory with a reflecting telescope
of large size, but which had never gained a commanding reputation.
No member of the staff at first seemed ambitious to get hold of such
an instrument, but, in time, Keeler gave it a trial in photographing
nebulæ.  Then it was found that a new field lay open.  The newly
acquired reflector proved far superior to other instruments for this
purpose, the photographic plates showing countless nebulæ in every
part of the sky, which the human eye was incapable of discerning in
the most powerful of telescopes.

In 1892, only four years after the mounting of the telescope, came
the surprising announcement that the work of Galileo on Jupiter had
been continued by the discovery of a fifth satellite to that planet.
This is the most difficult object in the solar system, only one or two
observers besides Barnard having commanded the means of seeing it.
The incident of my first acquaintance with the discoverer is not
flattering to my pride, but may be worth recalling.

In 1877 I was president of the American Association for the
Advancement of Science at the meeting held in Nashville.  There I was
told of a young man a little over twenty years of age, a photographer
by profession, who was interested in astronomy, and who desired to see
me.  I was, of course, very glad to make his acquaintance.  I found
that with his scanty earnings he had managed either to purchase or
to get together the materials for making a small telescope.  He was
desirous of doing something with it that might be useful in astronomy,
and wished to know what suggestions I could make in that line.  I did
not for a moment suppose that there was a reasonable probability of
the young man doing anything better than amuse himself.  At the same
time, feeling it a duty to encourage him, I suggested that there
was only one thing open to an astronomical observer situated as he
was, and that was the discovery of comets.  I had never even looked
for a comet myself, and knew little about the methods of exploring
the heavens for one, except what had been told me by H. P. Tuttle.
But I gave him the best directions I could, and we parted.  It is
now rather humiliating that I did not inquire more thoroughly into
the case.  It would have taken more prescience than I was gifted
with to expect that I should live to see the bashful youth awarded
the gold medal of the Royal Astronomical Society for his work.

The term of Holden's administration extended through some ten
years.  To me its most singular feature was the constantly growing
unpopularity of the director.  I call it singular because, if we
confine ourselves to the record, it would be difficult to assign
any obvious reason for it.  One fact is indisputable, and that
is the wonderful success of the director in selecting young men
who were to make the institution famous by their abilities and
industry.  If the highest problem of administration is to select
the right men, the new director certainly mastered it.  So far as
liberty of research and publication went, the administration had
the appearance of being liberal in the extreme.  Doubtless there
was another side to the question.  Nothing happens spontaneously,
and the singular phenomenon of one who had done all this becoming a
much hated man must have an adequate cause.  I have several times,
from pure curiosity, inquired about the matter of well-informed men.
On one occasion an instance of maladroitness was cited in reply.

"True," said I, "it was not exactly the thing to do, but, after all,
that is an exceedingly small matter."

"Yes," was the answer, "that was a small thing, but put a thousand
small things like that together, and you have a big thing."

A powerful factor in the case may have been his proceeding, within
a year of his appointment, to file an astounding claim for the sum
of $12,000 on account of services rendered to the observatory in
the capacity of general adviser before his appointment as director.
These services extended from the beginning of preparations in 1874
up to the completion of the work.  The trustees in replying to the
claim maintained that I had been their principal adviser in preparing
the plans.  However true this may have been, it was quite evident,
from Holden's statement, that they had been consulting him on a much
larger scale than I had been aware of.  This, however, was none of
my concern.  I ventured to express the opinion that the movement
was made merely to place on record a statement of the director's
services; and that no serious intention of forcing the matter to a
legal decision was entertained.  This surmise proved to be correct,
as nothing more was heard of the claim.

Much has been said of the effect of the comparative isolation of such
a community, which is apt to be provocative of internal dissension.
But this cause has not operated in the case of Holden's successors.
Keeler became the second director in 1897, and administered his office
with, so far as I know, universal satisfaction till his lamented
death in 1900.  It would not be a gross overstatement to say that his
successor was named by the practically unanimous voice of a number
of the leading astronomers of the world who were consulted on the
subject, and who cannot but be pleased to see how completely their
advice has been justified by the result of Campbell's administration.




VIII

THE AUTHOR'S SCIENTIFIC WORK


Perhaps an apology is due to the reader for my venturing to devote a
chapter to my own efforts in the scientific line.  If so, I scarcely
know what apology to make, unless it is that one naturally feels
interested in matters relating to his own work, and hopes to share
that interest with his readers, and that it is easier for one to write
such an account for himself than for any one else to do it for him.

Having determined to devote my life to the prosecution of exact
astronomy, the first important problem which I took up, while at
Cambridge, was that of the zone of minor planets, frequently called
asteroids, revolving between the orbits of Mars and Jupiter.  It was
formerly supposed that these small bodies might be fragments of a
large planet which had been shattered by a collision or explosion.
If such were the case, the orbits would, for a time at least, all
pass through the point at which the explosion occurred.  When only
three or four were known, it was supposed that they did pass nearly
through the same point.  When this was found not to be the case,
the theory of an explosion was in no way weakened, because, owing
to the gradual changes in the form and position of the orbits,
produced by the attraction of the larger planets, these orbits would
all move away from the point of intersection, and, in the course of
thousands of years, be so mixed up that no connection could be seen
between them.  This result was that nothing could be said upon the
subject except that, if the catastrophe ever did occur, it must have
been many thousand years ago.  The fact did not in any way militate
against the theory because, in view of the age of the universe, the
explosion might as well have occurred hundreds of thousands or even
millions of years ago as yesterday.  To settle the question, general
formulæ must be found by which the positions of these orbits could
be determined at any time in the past, even hundreds of thousands of
years back.  The general methods of doing this were known, but no
one had applied them to the especial case of these little planets.
Here, then, was an opportunity of tracing back the changes in these
orbits through thousands of centuries in order to find whether, at
a certain epoch in the past, so great a cataclysm had occurred as
the explosion of a world.  Were such the case, it would be possible
almost to set the day of the occurrence.  How great a feat would it
be to bring such an event at such a time to light!

I soon found that the problem, in the form in which it had been
attacked by previous mathematicians, involved no serious difficulty.
At the Springfield meeting of the American Association for the
Advancement of Science, in 1859, I read a paper explaining the
method, and showed by a curve on the blackboard the changes
in the orbit of one of the asteroids for a period, I think, of
several hundred thousand years,--"beyond the memory of the oldest
inhabitants"--said one of the local newspapers.  A month later it was
extended to three other asteroids, and the result published in the
"Astronomical Journal."  In the following spring, 1860, the final
results of the completed work were communicated to the American
Academy of Arts and Sciences in a paper "On the Secular Variations
and Mutual Relations of the Orbits of the Asteroids."  The question
of the possible variations in the orbits and the various relations
amongst them were here fully discussed.  One conclusion was that,
so far as our present theory could show, the orbits had never passed
through any common point of intersection.

The whole trend of thought and research since that time has been
toward the conclusion that no such cataclysm as that looked for ever
occurred, and that the group of small planets has been composed of
separate bodies since the solar system came into existence.  It was,
of course, a great disappointment not to discover the cataclysm, but
next best to finding a thing is showing that it is not there.  This,
it may be remarked, was the first of my papers to attract especial
notice in foreign scientific journals, though I had already published
several short notes on various subjects in the "Astronomical Journal."

At this point I may say something of the problems of mathematical
astronomy in the middle of the last century.  It is well known that
we shall at least come very near the truth when we say that the
planets revolve around the sun, and the satellites around their
primaries according to the law of gravitation.  We may regard all
these bodies as projected into space, and thus moving according to
laws similar to that which governs the motion of a stone thrown
from the hand.  If two bodies alone were concerned, say the sun
and a planet, the orbit of the lesser around the greater would be
an ellipse, which would never change its form, size, or position.
That the orbits of the planets and asteroids do change, and that they
are not exact ellipses, is due to their attraction upon each other.
The question is, do these mutual attractions completely explain all
the motions down to the last degree of refinement?  Does any world
move otherwise than as it is attracted by other worlds?

Two different lines of research must be brought to bear on the
question thus presented.  We must first know by the most exact and
refined observations that the astronomer can make exactly how a
heavenly body does move.  Its position, or, as we cannot directly
measure distance, its direction from us, must be determined as
precisely as possible from time to time.  Its course has been
mapped out for it in advance by tables which are published in the
"Astronomical Ephemeris," and we may express its position by its
deviation from these tables.  Then comes in the mathematical problem
how it ought to move under the attraction of all other heavenly bodies
that can influence its motion.  The results must then be compared,
in order to see to what conclusion we may be led.

This mathematical side of the question is of a complexity beyond
the powers of ordinary conception.  I well remember that when,
familiar only with equations of algebra, I first looked into a
book on mechanics, I was struck by the complexity of the formulæ.
But this was nothing to what one finds when he looks into a work on
celestial mechanics, where a single formula may fill a whole chapter.
The great difficulty arises from the fact that the constant action
upon a planet exerted at every moment of time through days and
years by another planet affects its motion in all subsequent time.
The action of Jupiter upon our earth this morning changes its motion
forever, just as a touch upon a ball thrown by a pitcher will change
the direction of the ball through its whole flight.

The wondrous perfection of mathematical research is shown by the
fact that we can now add up, as it were, all these momentary effects
through years and centuries, with a view of determining the combined
result at any one moment.  It is true that this can be done only in an
imperfect way, and at the expense of enormous labor; but, by putting
more and more work into it, investigating deeper and deeper, taking
into account smaller and smaller terms of our formulæ, and searching
for the minutest effects, we may gradually approach, though we may
never reach, absolute exactness.  Here we see the first difficulty
in reaching a definite conclusion.  One cannot be quite sure that
a deviation is not due to some imperfection in mathematical method
until he and his fellows have exhausted the subject so thoroughly
as to show that no error is possible.  This is hard indeed to do.

Taking up the question on the observational side, a source of
difficulty and confusion at once presented itself.  The motions
of a heavenly body from day to day and year to year are mapped out
by comparative observations on it and on the stars.  The question
of the exact positions of the stars thus comes in.  In determining
these positions with the highest degree of precision, a great variety
of data have to be used.  The astronomer cannot reach a result by a
single step, nor by a hundred steps.  He is like a sculptor chiseling
all the time, trying to get nearer and nearer the ideal form of his
statue, and finding that with every new feature he chisels out,
a defect is brought to light in other features.  The astronomer,
when he aims at the highest mathematical precision in his results,
finds Nature warring with him at every step, just as if she wanted
to make his task as difficult as possible.  She alters his personal
equation when he gets tired, makes him see a small star differently
from a bright one, gives his instrument minute twists with heat and
cold, sends currents of warm or cold air over his locality, which
refract the rays of light, asks him to keep the temperature in which
he works the same as that outside, in order to avoid refraction when
the air enters his observing room, and still will not let him do it,
because the walls and everything inside the room, being warmed up
during the day, make the air warmer than it is outside.  With all
these obstacles which she throws in his way he must simply fight the
best he can, exerting untiring industry to eliminate their effects
by repeated observations under a variety of conditions.

A necessary conclusion from all this is that the work of all observing
astronomers, so far as it could be used, must be combined into a
single whole.  But here again difficulties are met at every step.
There has been, in times past, little or no concert of action among
astronomers at different observatories.  The astronomers of each
nation, perhaps of each observatory, to a large extent, have gone
to work in their own way, using discordant data, perhaps not always
rigidly consistent, even in the data used in a single establishment.
How combine all the astronomical observations, found scattered
through hundreds of volumes, into a homogeneous whole?

What is the value of such an attempt?  Certainly if we measure value
by the actual expenditure of nations and institutions upon the work,
it must be very great.  Every civilized nation expends a large annual
sum on a national observatory, while a still greater number of such
institutions are supported at corporate expense.  Considering that
the highest value can be derived from their labors only by such a
combination as I have described, we may say the result is worth an
important fraction of what all the observatories of the world have
cost during the past century.

Such was, in a general way, the great problem of exact astronomy
forty or fifty years ago.  Its solution required extended coöperation,
and I do not wish to give the impression that I at once attacked it,
or even considered it as a whole.  I could only determine to do my
part in carrying forward the work associated with it.

Perhaps the most interesting and important branch of the problem
concerned the motion of the moon.  This had been, ever since the
foundation of the Greenwich Observatory, in 1670, a specialty
of that institution.  It is a curious fact, however, that while
that observatory supplied all the observations of the moon,
the investigations based upon these observations were made almost
entirely by foreigners, who also constructed the tables by which the
moon's motion was mapped out in advance.  The most perfect tables
made were those of Hansen, the greatest master of mathematical
astronomy during the middle of the century, whose tables of the
moon were published by the British government in 1857.  They were
based on a few of the Greenwich observations from 1750 to 1850.
The period began with 1750, because that was the earliest at which
observations of any exactness were made.  Only a few observations
were used, because Hansen, with the limited computing force at
his command,--only a single assistant, I believe,--was not able to
utilize a great number of the observations.  The rapid motion of the
moon, a circuit being completed in less than a month, made numerous
observations necessary, while the very large deviations in the
motion produced by the attraction of the sun made the problem of the
mathematical theory of that motion the most complicated in astronomy.
Thus it happened that, when I commenced work at the Naval Observatory
in 1861, the question whether the moon exactly followed the course
laid out for her by Hansen's tables was becoming of great importance.

The same question arose in the case of the planets.  So from a
survey of the whole field, I made observations of the sun, moon,
and planets my specialty at the observatory.  If the astronomical
reader has before him the volume of observations for 1861, he will,
by looking at pages 366-440, be able to infer with nearly astronomical
precision the date when I reported for duty.

For a year or two our observations showed that the moon seemed
to be falling a little behind her predicted motion.  But this soon
ceased, and she gradually forged ahead in a much more remarkable way.
In five or six years it was evident that this was becoming permanent;
she was a little farther ahead every year.  What could it mean?
To consider this question, I may add a word to what I have already
said on the subject.

In comparing the observed and predicted motion of the moon,
mathematicians and astronomers, beginning with Laplace, have been
perplexed by what are called "inequalities of long period."  For a
number of years, perhaps half a century, the moon would seem to be
running ahead, and then she would gradually relax her speed and fall
behind.  Laplace suggested possible causes, but could not prove them.
Hansen, it was supposed, had straightened out the tangle by showing
that the action of Venus produced a swinging of this sort in the
moon; for one hundred and thirty years she would be running ahead
and then for one hundred and thirty years more falling back again,
like a pendulum.  Two motions of this sort were combined together.
They were claimed to explain the whole difficulty.  The moon, having
followed Hansen's theory for one hundred years, would not be likely
to deviate from it.  Now, it was deviating.  What could it mean?

Taking it for granted, on Hansen's authority, that his tables
represented the motions of the moon perfectly since 1750, was there no
possibility of learning anything from observations before that date?
As I have already said, the published observations with the usual
instruments were not of that refined character which would decide
a question like this.  But there is another class of observations
which might possibly be available for the purpose.

Millions of stars, visible with large telescopes, are scattered
over the heavens; tens of thousands are bright enough to be seen
with small instruments, and several thousand are visible to any
ordinary eye.  The moon, in her monthly course around the heavens,
often passes over a star, and of course hides it from view during
the time required for the passage.  The great majority of stars
are so small that their light is obscured by the effulgence of
the moon as the latter approaches them.  But quite frequently the
star passed over is so bright that the exact moment when the moon
reaches it can be observed with the utmost precision.  The star then
disappears from view in an instant, as if its light were suddenly
and absolutely extinguished.  This is called an occultation.
If the moment at which the disappearance takes place is observed,
we know that at that instant the apparent angle between the centre
of the moon and the star is equal to the moon's semi-diameter.
By the aid of a number of such observations, the path of the moon in
the heavens, and the time at which she arrives at each point of the
path, can be determined.  In order that the determination may be of
sufficient scientific precision, the time of the occultation must be
known within one or two seconds; otherwise, we shall be in doubt how
much of the discrepancy may be due to the error of the observation,
and how much to the error of the tables.

Occultations of some bright stars, such as Aldebaran and Antares,
can be observed by the naked eye; and yet more easily can those of
the planets be seen.  It is therefore a curious historic fact that
there is no certain record of an actual observation of this sort
having been made until after the commencement of the seventeenth
century.  Even then the observations were of little or no use,
because astronomers could not determine their time with sufficient
precision.  It was not till after the middle of the century, when the
telescope had been made part of astronomical instruments for finding
the altitude of a heavenly body, and after the pendulum clock had
been invented by Huyghens, that the time of an occultation could be
fixed with the required exactness.  Thus it happens that from 1640
to 1670 somewhat coarse observations of the kind are available, and
after the latter epoch those made by the French astronomers become
almost equal to the modern ones in precision.

The question that occurred to me was: Is it not possible that such
observations were made by astronomers long before 1750?  Searching
the published memoirs of the French Academy of Sciences and the
Philosophical Transactions, I found that a few such observations were
actually made between 1660 and 1700.  I computed and reduced a few of
them, finding with surprise that Hansen's tables were evidently much
in error at that time.  But neither the cause, amount, or nature of
the error could be well determined without more observations than
these.  Was it not possible that these astronomers had made more
than they published?  The hope that material of this sort existed
was encouraged by the discovery at the Pulkowa Observatory of an
old manuscript by the French astronomer Delisle, containing some
observations of this kind.  I therefore planned a thorough search
of the old records in Europe to see what could be learned.

The execution of this plan was facilitated by the occurrence,
in December, 1870, of an eclipse of the sun in Spain and along the
Mediterranean.  A number of parties were going out from this country
to observe it, two of which were fitted out at the Naval Observatory.
I was placed in charge of one of these, consisting, practically,
of myself.  The results of my observation would be of importance
in the question of the moon's motion, but, although the eclipse was
ostensibly the main object, the proposed search of the records was
what I really had most in view.  In Paris was to be found the most
promising mine; but the Franco-Prussian war was then going on, and
I had to wait for its termination.  Then I made a visit to Paris,
which will be described in a later chapter.

At the observatory the old records I wished to consult were placed
at my disposal, with full liberty not only to copy, but to publish
anything of value I could find in them.  The mine proved rich beyond
the most sanguine expectation.  After a little prospecting, I found
that the very observations I wanted had been made in great numbers
by the Paris astronomers, both at the observatory and at other points
in the city.

And how, the reader may ask, did it happen that these observations
were not published by the astronomers who made them?  Why should they
have lain unused and forgotten for two hundred years?  The answer to
these questions is made plain enough by an examination of the records.
The astronomers had no idea of the possible usefulness and value of
what they were recording.  So far as we can infer from their work,
they made the observations merely because an occultation was an
interesting thing to see; and they were men of sufficient scientific
experience and training to have acquired the excellent habit of
noting the time at which a phenomenon was observed.  But they
were generally satisfied with simply putting down the clock time.
How they could have expected their successors to make any use of
such a record, or whether they had any expectations on the subject,
we cannot say with confidence.  It will be readily understood that no
clocks of the present time (much less those of two hundred years ago)
run with such precision that the moment read from the clock is exact
within one or two seconds.  The modern astronomer does not pretend
to keep his clock correct within less than a minute; he determines
by observation how far it is wrong, on each date of observation,
and adds so much to the time given by the clock, or subtracts it,
as the case may be, in order to get the correct moment of true time.
In the case of the French astronomers, the clock would frequently
be fifteen minutes or more in error, for the reason that they used
apparent time, instead of mean time as we do.  Thus when, as was often
the case, the only record found was that, at a certain hour, minute,
and second, by a certain clock, _une étoile se cache par la lune_,
a number of very difficult problems were presented to the astronomer
who was to make use of the observations two centuries afterward.
First of all, he must find out what the error of the clock was at the
designated hour, minute, and second; and for this purpose he must
reduce the observations made by the observer in order to determine
the error.  But it was very clear that the observer did not expect
any successor to take this trouble, and therefore did not supply
him with any facilities for so doing.  He did not even describe
the particular instrument with which the observations were made,
but only wrote down certain figures and symbols, of a more or less
hieroglyphic character.  It needed much comparison and examination
to find out what sort of an instrument was used, how the observations
were made, and how they should be utilized for the required purpose.

Generally the star which the moon hid was mentioned, but not in all
cases.  If it was not, the identification of the star was a puzzling
problem.  The only way to proceed was to calculate the apparent
position of the centre of the moon as seen by an observer at the Paris
Observatory, at the particular hour and minute of the observation.
A star map was then taken; the points of a pair of dividers were
separated by the length of the moon's radius, as it would appear
on the scale of the map; one point of the dividers was put into
the position of the moon's centre on the map, and with the other a
circle was drawn.  This circle represented the outline of the moon,
as it appeared to the observer at the Paris Observatory, at the hour
and minute in question, on a certain day in the seventeenth century.
The star should be found very near the circumference of the circle,
and in nearly all cases a star was there.

Of course all this could not be done on the spot.  What had to be
done was to find the observations, study their relations and the
method of making them, and copy everything that seemed necessary
for working them up.  This took some six weeks, but the material I
carried away proved the greatest find I ever made.  Three or four
years were spent in making all the calculations I have described.
Then it was found that seventy-five years were added, at a single
step, to the period during which the history of the moon's motion
could be written.  Previously this history was supposed to commence
with the observations of Bradley, at Greenwich, about 1750; now it
was extended back to 1675, and with a less degree of accuracy thirty
years farther still.  Hansen's tables were found to deviate from
the truth, in 1675 and subsequent years, to a surprising extent;
but the cause of the deviation is not entirely unfolded even now.

During the time I was doing this work, Paris was under the reign
of the Commune and besieged by the national forces.  The studies
had to be made within hearing of the besieging guns; and I could
sometimes go to a window and see flashes of artillery from one of the
fortifications to the south.  Nearly every day I took a walk through
the town, occasionally as far as the Arc.  As my observations during
these walks have no scientific value, I shall postpone an account
of what I saw to another chapter.

One curious result of this work is that the longitude of the moon may
now be said to be known with greater accuracy through the last quarter
of the seventeenth century than during the ninety years from 1750 to
1840.  The reason is that, for this more modern period, no effective
comparison has been made between observations and Hansen's tables.


Just as this work was approaching completion I was called upon to
decide a question which would materially influence all my future
activity.  The lamented death of Professor Winlock in 1875 left vacant
the directorship of the Harvard Observatory.  A month or two later I
was quite taken by surprise to receive a letter from President Eliot
tendering me this position.  I thus had to choose between two courses.
One led immediately to a professorship in Harvard University,
with all the distinction and worldly advantages associated with it,
including complete freedom of action, an independent position, and
the opportunity of doing such work as I deemed best with the limited
resources at the disposal of the observatory.  On the other hand
was a position to which the official world attached no importance,
and which brought with it no worldly advantages whatever.

I first consulted Mr. Secretary Robeson on the matter.  The force with
which he expressed himself took me quite by surprise.  "By all means
accept the place; don't remain in the government service a day longer
than you have to.  A scientific man here has no future before him, and
the quicker he can get away the better."  Then he began to descant on
our miserable "politics" which brought about such a state of things.

Such words, coming from a sagacious head of a department who, one
might suppose, would have been sorry to part with a coadjutor of
sufficient importance to be needed by Harvard University, seemed to
me very suggestive.  And yet I finally declined the place, perhaps
unwisely for myself, though no one who knows what the Cambridge
Observatory has become under Professor Pickering can feel that
Harvard has any cause to regret my decision.  An apology for it on
my own behalf will seem more appropriate.

On the Cambridge side it must be remembered that the Harvard
Observatory was then almost nothing compared with what it is now.
It was poor in means, meagre in instrumental outfit, and wanting in
working assistants; I think the latter did not number more than three
or four, with perhaps a few other temporary employees.  There seemed
little prospect of doing much.

On the Washington side was the fact that I was bound to Washington
by family ties, and that, if Harvard needed my services, surely
the government needed them much more.  True, this argument was,
for the time, annulled by the energetic assurance of Secretary
Robeson, showing that the government felt no want of any one in
its service able to command a university professorship.  But I was
still pervaded by the optimism of youth in everything that concerned
the future of our government, and did not believe that, with the
growth of intelligence in our country, an absence of touch between
the scientific and literary classes on the one side, and "politics"
on the other, could continue.  In addition to this was the general
feeling by which I have been actuated from youth--that one ought to
choose that line of activity for which Nature had best fitted him,
trusting that the operation of moral causes would, in the end,
right every wrong, rather than look out for place and preferment.
I felt that the conduct of government astronomy was that line of
activity for which I was best fitted, and that, in the absence
of strong reason to the contrary, it had better not be changed.
In addition to these general considerations was the special point
that, in the course of a couple of years, the directorship of the
Nautical Almanac would become vacant, and here would be an unequaled
opportunity for carrying on the work in mathematical astronomy I
had most at heart.  Yet, could I have foreseen that the want of
touch which I have already referred to would not be cured, that I
should be unable to complete the work I had mapped out before my
retirement, or to secure active public interest in its continuance,
my decision would perhaps have been different.

On September 15, 1877, I took charge of the Nautical Almanac Office.
The change was one of the happiest of my life.  I was now in a
position of recognized responsibility, where my recommendations met
with the respect due to that responsibility, where I could make plans
with the assurance of being able to carry them out, and where the
countless annoyances of being looked upon as an important factor in
work where there was no chance of my being such would no longer exist.
Practically I had complete control of the work of the office, and
was thus, metaphorically speaking, able to work with untied hands.
It may seem almost puerile to say this to men of business experience,
but there is a current notion, spread among all classes, that because
the Naval Observatory has able and learned professors, therefore
they must be able to do good and satisfactory work, which may be
worth correcting.

I found my new office in a rather dilapidated old dwelling-house,
about half a mile or less from the observatory, in one of those
doubtful regions on the border line between a slum and the lowest
order of respectability.  If I remember aright, the only occupants
of the place were the superintendent, my old friend Mr. Loomis,
senior assistant, who looked after current business, a proof-reader
and a messenger.  All the computers, including even one copyist,
did their work at their homes.

A couple of changes had to be made in the interest of efficiency.
The view taken of one of these may not only interest the reader,
but give him an idea of what people used to think of government
service before the era of civil service reform.  The proof-reader
was excellent in every respect except that of ability to perform
his duty.  He occupied a high position, I believe, in the Grand
Army of the Republic, and thus wielded a good deal of influence.
When his case was appealed to the Secretary of the Navy, apellant
was referred to me.  I stated the trouble to counsel,--he did not
appear to see figures, or be able to distinguish whether they were
right or wrong, and therefore was useless as a proof-reader.

"It is not his fault," was the reply; "he nearly lost his eyesight
in the civil war, and it is hard for him to see at all."  In the
view of counsel that explanation ought to have settled the case in
his favor.  It did not, however, but "influence" had no difficulty
in making itself more successful in another field.

Among my first steps was that of getting a new office in the top of
the Corcoran Building, then just completed.  It was large and roomy
enough to allow quite a number of assistants around me.

Much of the work was then, as now, done by the piece, or annual
job, the computers on it very generally working at their homes.
This offers many advantages for such work; the government is not
burdened with an officer who must be paid his regular monthly salary
whether he supplies his work or not, and whom it is unpleasant and
difficult to get rid of in case of sickness or breakdown of any
sort.  The work is paid for when furnished, and the main trouble of
administration saved.  It is only necessary to have a brief report
from time to time, showing that the work is actually going on.

I began with a careful examination of the relation of prices to work,
making an estimate of the time probably necessary to do each job.
Among the performers of the annual work were several able and eminent
professors at various universities and schools.  I found that they
were being paid at pretty high professional prices.  I recall with
great satisfaction that I was able to reduce the prices and, step by
step, concentrate all the work in Washington, without detriment to
the pleasant relations I sustained with these men, some of them old
and intimate friends.  These economies went on increasing year by
year, and every dollar that was saved went into the work of making
the tables necessary for the future use of the Ephemeris.

The programme of work which I mapped out, involved, as one branch of
it, a discussion of all the observations of value on the positions
of the sun, moon, and planets, and incidentally, on the bright fixed
stars, made at the leading observatories of the world since 1750.
One might almost say it involved repeating, in a space of ten or
fifteen years, an important part of the world's work in astronomy for
more than a century past.  Of course, this was impossible to carry out
in all its completeness.  In most cases what I was obliged practically
to confine myself to was a correction of the reductions already made
and published.  Still, the job was one with which I do not think
any astronomical one ever before attempted by a single person could
compare in extent.  The number of meridian observations on the sun,
Mercury, Venus, and Mars alone numbered 62,030.  They were made at the
observatories of Greenwich, Paris, Königsberg, Pulkowa, Cape of Good
Hope,--but I need not go over the entire list, which numbers thirteen.

The other branches of the work were such as I have already
described,--the computation of the formulæ for the perturbation of
the various planets by each other.  As I am writing for the general
reader, I need not go into any further technical description of this
work than I have already done.  Something about my assistants may,
however, be of interest.  They were too numerous to be all recalled
individually.  In fact, when the work was at its height, the office
was, in the number of its scientific employees, nearly on an equality
with the three or four greatest observatories of the world.

One of my experiences has affected my judgment on the general morale
of the educated young men of our country.  In not a single case did I
ever have an assistant who tried to shirk his duty to the government,
nor do I think there was more than a single case in which one tried
to contest my judgment of his own merits, or those of his work.
I adopted the principle that promotion should be by merit rather than
by seniority, and my decisions on that matter were always accepted
without complaint.  I recall two men who voluntarily resigned when
they found that, through failure of health or strength, they were
unable to properly go on with their work.  In frankness I must admit
that there was one case in which I had a very disagreeable contest in
getting rid of a learned gentleman whose practical powers were so far
inferior to his theoretical knowledge that he was almost useless in
the office.  He made the fiercest and most determined fight in which
I was ever engaged, but I must, in justice to all concerned, say that
his defect was not in will to do his work but in the requisite power.
Officially I was not without fault, because, in the press of matters
requiring my attention, I had entrusted too much to him, and did
not discover his deficiencies until some mischief had been done.


Perhaps the most eminent and interesting man associated with me
during this period was Mr. George W. Hill, who will easily rank as
the greatest master of mathematical astronomy during the last quarter
of the nineteenth century.  The only defect of his make-up of which
I have reason to complain is the lack of the teaching faculty.
Had this been developed in him, I could have learned very much
from him that would have been to my advantage.  In saying this
I have one especial point in mind.  In beginning my studies in
celestial mechanics, I lacked the guidance of some one conversant
with the subject on its practical side.  Two systems of computing
planetary perturbations had been used, one by Leverrier, while the
other was invented by Hansen.  The former method was, in principle,
of great simplicity, while the latter seemed to be very complex and
even clumsy.  I naturally supposed that the man who computed the
direction of the planet Neptune before its existence was known, must
be a master of the whole subject, and followed the lines he indicated.
I gradually discovered the contrary, and introduced modified methods,
but did not entirely break away from the old trammels.  Hill had never
been bound by them, and used Hansen's method from the beginning.
Had he given me a few demonstrations of its advantages, I should
have been saved a great deal of time and labor.

The part assigned to Hill was about the most difficult in the whole
work,--the theory of Jupiter and Saturn.  Owing to the great mass of
these "giant planets," the inequalities of their motion, especially
in the case of Saturn, affected by the attraction of Jupiter, is
greater than in the case of the other planets.  Leverrier failed to
attain the necessary exactness in his investigation of their motion.
Hill had done some work on the subject at his home in Nyack Turnpike
before I took charge of the office.  He now moved to Washington,
and seriously began the complicated numerical calculations which
his task involved.  I urged that he should accept the assistance of
less skilled computers; but he declined it from a desire to do the
entire work himself.  Computers to make the duplicate computations
necessary to guard against accidental numerical errors on his part
were all that he required.  He labored almost incessantly for about
ten years, when he handed in the manuscript of what now forms Volume
IV. of the "Astronomical Papers."

A pleasant incident occurred in 1884, when the office was honored
by a visit from Professor John C. Adams of England, the man who,
independently of Leverrier, had computed the place of Neptune, but
failed to receive the lion's share of the honor because it happened to
be the computations of the Frenchman and not his which led immediately
to the discovery of the planet.  It was of the greatest interest to
me to bring two such congenial spirits as Adams and Hill together.

It would be difficult to find a more impressive example than
that afforded by Hill's career, of the difficulty of getting the
public to form and act upon sane judgments in such cases as his.
The world has the highest admiration for astronomical research, and
in this sentiment our countrymen are foremost.  They spend hundreds
of thousands of dollars to promote it.  They pay good salaries to
professors who chance to get a certain official position where they
may do good work.  And here was perhaps the greatest living master in
the highest and most difficult field of astronomy, winning world-wide
recognition for his country in the science, and receiving the salary
of a department clerk.  I never wrestled harder with a superior
than I did with Hon. R. W. Thompson, Secretary of the Navy, about
1880, to induce him to raise Mr. Hill's salary from $1200 to $1400.
It goes without saying that Hill took even less interest in the
matter than I did.  He did not work for pay, but for the love of
science.  His little farm at Nyack Turnpike sufficed for his home,
and supplied his necessities so long as he lived there, and all
he asked in Washington was the means of going on with his work.
The deplorable feature of the situation is, that this devotion to
his science, instead of commanding due recognition on the public
and official side, rather tended to create an inadequate impression
of the importance of what he was doing.  That I could not secure
for him at least the highest official consideration is among the
regretful memories of my official life.

Although, so far as the amount of labor is concerned, Mr. Hill's
work upon Jupiter and Saturn is the most massive he ever undertook,
his really great scientific merit consists in the development of a
radically new method of computing the inequalities of the moon's
motion, which is now being developed and applied by Professor
E. W. Brown.  His most marked intellectual characteristic is the
eminently practical character of his researches.  He does not aim
so much at elegant mathematical formulæ, as to determine with the
greatest precision the actual quantities of which mathematical
astronomy stands in need.  In this direction he has left every
investigator of recent or present time far in the rear.

After the computations on Jupiter and Saturn were made, it was
necessary to correct their orbits and make tables of their motions.
This work I left entirely in Mr. Hill's hands, the only requirement
being that the masses of the planets and other data which he
adopted should be uniform with those I used in the rest of the
work.  His tables were practically completed in manuscript at the
beginning of 1892.  When they were through, doubtless feeling, as
well he might, that he had done his whole duty to science and the
government, Mr. Hill resigned his office and returned to his home.
During the summer he paid a visit to Europe, and visiting the
Cambridge University, was honored with the degree of Doctor of Laws,
along with a distinguished company, headed by the Duke of Edinburgh.
One of the pleasant things to recall was that, during the fifteen
years of our connection, there was never the slightest dissension
or friction between us.

I may add that the computations which he made on the theory of
Jupiter and Saturn are all preserved complete and in perfect form
at the Nautical Almanac Office, so that, in case any question should
arise respecting them in future generations, the point can be cleared
up by an inspection.


In 1874, three years before I left the observatory, I was informed
by Dr. Henry Draper that he had a mechanical assistant who showed
great fondness for and proficiency in some work in mathematical
astronomy.  I asked to see what he was doing, and received a
collection of papers of a remarkable kind.  They consisted mainly
of some of the complicated developments of celestial mechanics.
In returning them I wrote to Draper that, when I was ready to begin
my work on the planetary theories, I must have his man,--could he
possibly be spared?  But he came to me before the time, while I was
carrying on some investigations with aid afforded by the Smithsonian
Institution.  Of course, when I took charge of the Nautical Almanac
Office, he was speedily given employment on its work.  His name
was John Meier, a Swiss by birth, evidently from the peasant class,
but who had nevertheless been a pupil of Professor Rudolph Wolf at
Zurich.  Emigrating to this country, he was, during the civil war,
an engineer's mate or something of that grade in the navy.  He was
the most perfect example of a mathematical machine that I ever had
at command.  Of original power,--the faculty of developing new methods
and discovering new problems, he had not a particle.  Happily for his
peace of mind, he was totally devoid of worldly ambition.  I had only
to prepare the fundamental data for him, explain what was wanted,
write down the matters he was to start with, and he ground out
day after day the most complicated algebraic and trigonometrical
computations with untiring diligence and almost unerring accuracy.

But a dark side of the picture showed itself very suddenly and
unexpectedly in a few years.  For the most selfish reasons, if for
no others, I desired that his peace of mind should be undisturbed.
The result was that I was from time to time appealed to as an
arbitrator of family dissensions, in which it was impossible to
say which side was right and which wrong.  Then, as a prophylactic
against malaria, his wife administered doses of whiskey.  The rest
of the history need not be told.  It illustrates the maxim that
"blood will tell," which I fear is as true in scientific work as in
any other field of human activity.

A man of totally different blood, the best in fact, entered the
office shortly before Meier broke down.  This was Mr. Cleveland
Keith, son of Professor Reuel Keith, who was one of the professors
at the observatory when it was started.  His patience and ability
led to his gradually taking the place of a foreman in supervising
the work pertaining to the reduction of the observations, and the
construction of the tables of the planets.  Without his help, I fear
I should never have brought the tables to a conclusion.  He died in
1896, just as the final results of the work were being put together.


High among the troublesome problems with which I had to deal while
in charge of the Nautical Almanac, was that of universal time.
All but the youngest of my readers will remember the period when every
railway had its own meridian, by the time of which its trains were
run, which had to be changed here and there in the case of the great
trunk lines, and which seldom agreed with the local time of a place.
In the Pennsylvania station at Pittsburg were three different times;
one that of Philadelphia, one of some point farther west, and the
third the local Pittsburg time.  The traveler was constantly liable
to miss a train, a connection, or an engagement by the doubt and
confusion thus arising.

This was remedied in 1883 by the adoption of our present system of
standard times of four different meridians, the introduction of which
was one of the great reforms of our generation.  When this change
was made, I was in favor of using Washington time as the standard,
instead of going across the ocean to Greenwich for a meridian.
But those who were pressing the measure wanted to have a system for
the whole world, and for this purpose the meridian of Greenwich was
the natural one.  Practically our purpose was served as well by the
Greenwich meridian as it would have been by that of Washington.

The year following this change an international meridian conference
was held at Washington, on the invitation of our government, to
agree upon a single prime meridian to be adopted by the whole world
in measuring longitudes and indicating time.

Of course the meridian of Greenwich was the only one that would
answer the purpose.  This had already been adopted by several leading
maritime nations, including ourselves as well as Great Britain.
It was merely a question of getting the others to fall into line.
No conference was really necessary for this purpose, because the
dissentients caused much more inconvenience to themselves than to any
one else by their divergent practice.  The French held out against the
adoption of the Greenwich meridian, and proposed one passing through
Behring Strait.  I was not a member of the conference, but was invited
to submit my views, which I did orally.  I ventured to point out to
the Frenchmen that the meridian of Greenwich also belonged to France,
passing near Havre and intersecting their country from north to south.
It was therefore as much a French as an English meridian, and could
be adopted without any sacrifice of national position.  But they
were not convinced, and will probably hold out until England adopts
the metric system, on which occasion it is said that they will be
prepared to adopt the Greenwich meridian.

One proceeding of the conference illustrates a general characteristic
of reformers.  Almost without debate, certainly without adequate
consideration, the conference adopted a recommendation that
astronomers and navigators should change their system of reckoning
time.  Both these classes have, from time immemorial, begun the day
at noon, because this system was most natural and convenient, when
the question was not that of a measure of time for daily life, but
simply to indicate with mathematical precision the moment of an event.
Navigators had begun the day at noon, because the observations of the
sun, on which the latitude of a ship depends, are necessarily made at
noon, and the run of the ship is worked up immediately afterward.
The proposed change would have produced unending confusion in
astronomical nomenclature, owing to the difficulty of knowing in all
cases which system of time was used in any given treatise or record
of observations.  I therefore felt compelled, in the general interest
of science and public convenience, to oppose the project with all my
power, suggesting that, if the new system must be put into operation,
we should wait until the beginning of a new century.

"I hope you will succeed in having its adoption postponed until
1900," wrote Airy to me, "and when 1900 comes, I hope you will
further succeed in having it again postponed until the year 2000."

The German official astronomers, and indeed most of the official ones
everywhere, opposed the change, but the efforts on the other side
were vigorously continued.  The British Admiralty was strongly urged
to introduce the change into the Nautical Almanac, and the question
of doing this was warmly discussed in various scientific journals.

One result of this movement was that, in 1886, Rear-Admiral
George H. Belknap, superintendent of the Naval Observatory,
and myself were directed to report on the question.  I drew up a
very elaborate report, discussing the subject especially in its
relations to navigation, pointing out in the strongest terms I
could the danger of placing in the hands of navigators an almanac
in which the numbers were given in a form so different from that to
which they were accustomed.  If they chanced to forget the change,
the results of their computations might be out to any extent, to the
great danger and confusion of their reckoning, while not a solitary
advantage would be gained by it.

There is some reason to suppose that this document found its way
to the British Admiralty, but I never heard a word further on the
subject except that it ceased to be discussed in London.  A few years
later some unavailing efforts were made to revive the discussion, but
the twentieth century is started without this confusing change being
introduced into the astronomical ephemerides and nautical almanacs
of the world, and navigators are still at liberty to practice the
system they find most convenient.


In 1894 I had succeeded in bringing so much of the work as pertained
to the reduction of the observations and the determination of the
elements of the planets to a conclusion.  So far as the larger planets
were concerned, it only remained to construct the necessary tables,
which, however, would be a work of several years.

With the year 1896 came what was perhaps the most important event
in my whole plan.  I have already remarked upon the confusion which
pervaded the whole system of exact astronomy, arising from the
diversity of the fundamental data made use of by the astronomers of
foreign countries and various institutions in their work.  It was,
I think, rather exceptional that any astronomical result was based
on entirely homogeneous and consistent data.  To remedy this state of
things and start the exact astronomy of the twentieth century on one
basis for the whole world, was one of the objects which I had mapped
out from the beginning.  Dr. A. M. W. Downing, superintendent of the
British Nautical Almanac, was struck by the same consideration and
animated by the same motive.  He had especially in view to avoid
the duplication of work which arose from the same computations
being made in different countries for the same result, whereby much
unnecessary labor was expended.  The field of astronomy is so vast,
and the quantity of work urgently required to be done so far beyond
the power of any one nation, that a combination to avoid all such
waste was extremely desirable.  When, in 1895, my preliminary results
were published, he took the initiative in a project for putting the
idea into effect, by proposing an international conference of the
directors of the four leading ephemerides, to agree upon a uniform
system of data for all computations pertaining to the fixed stars.
This conference was held in Paris in May, 1896.  After several days
of discussion, it resolved that, beginning with 1901, a certain set
of constants should be used in all the ephemerides, substantially
the same as those I had worked out, but without certain ulterior,
though practically unimportant, modifications which I had applied
for the sake of symmetry.  My determination of the positions and
motions of the bright fixed stars, which I had not yet completed,
was adopted in advance for the same purpose, I agreeing to complete
it if possible in time for use in 1901.  I also agreed to make a new
determination of the constant of precession, that which I had used in
my previous work not being quite satisfactory.  All this by no means
filled the field of exact astronomy, yet what was left outside of it
was of comparatively little importance for the special object in view.

More than a year after the conference I was taken quite by surprise
by a vigorous attack on its work and conclusions on the part of
Professor Lewis Boss, director of the Dudley Observatory, warmly
seconded by Mr. S. C. Chandler of Cambridge, the editor of the
"Astronomical Journal."  The main grounds of attack were two
in number.  The time was not ripe for concluding upon a system of
permanent astronomical standards.  Besides this, the astronomers of
the country should have been consulted before a decision was reached.

Ultimately the attack led to a result which may appear curious to
the future astronomer.  He will find the foreign ephemerides using
uniform data worked out in the office of the "American Ephemeris and
Nautical Almanac" at Washington for the years beginning with 1901.
He will find that these same data, after being partially adopted in
the ephemeris for 1900, were thrown out in 1901, and the antiquated
ones reintroduced in the main body of the ephemeris.  The new ones
appear simply in an appendix.

As, under the operation of law, I should be retired from active
service in the March following the conference, it became a serious
question whether I should be able to finish the work that had been
mapped out, as well as the planetary tables.  Mr. Secretary Herbert,
on his own motion so far as I know, sent for me to inquire into the
subject.  The result of the conference was a movement on his part
to secure an appropriation somewhat less than the highest salary of
a professor, to compensate me for the completion of the work after
my retirement.  The House Committee on Appropriations, ever mindful
of economy in any new item, reduced the amount to a clerical salary.
The committee of conference compromised on a mean between the two.
It happened that the work on the stars was not specified in the
law,--only the tables of the planets.  In consequence I had no legal
right to go on with the former, although the ephemerides of Europe
were waiting for the results.  After much trouble an arrangement
was effected under which the computers on the work were not to be
prohibited from consulting me in its prosecution.

Astronomical work is never really done and finished.  The questions
growing out of the agreement or non-agreement of the tables with
observations still remain to be studied, and require an immense amount
of computation.  In what country and by whom these computations will
be made no one can now tell.  The work which I most regretted to leave
unfinished was that on the motion of the moon.  As I have already
said, this work is complete to 1750.  The computations for carrying
it on from 1750 to the present time were perhaps three fourths done
when I had to lay them aside.  In 1902, when the Carnegie Institution
was organized, it made a grant for supplying me with the computing
assistance and other facilities necessary for the work, and the
Secretary of the Navy allowed me the use of the old computations.
Under such auspices the work was recommenced in March, 1903.

So far as I can recall, I never asked anything from the government
which would in any way promote my personal interests.  The only
exception, if such it is, is that during the civil war I joined with
other professors in asking that we be put on the same footing with
other staff corps of the navy as regarded pay and rank.  So far as
my views were concerned, the rank was merely a _pro forma_ matter,
as I never could see any sound reason for a man pursuing astronomical
duties caring to have military rank.

In conducting my office also, the utmost economy was always studied.
The increase in the annual appropriations for which I asked was so
small that, when I left the office in 1877, they were just about the
same as they were back in the fifties, when it was first established.
The necessary funds were saved by economical administration.  All this
was done with a feeling that, after my retirement, the satisfaction
with which one could look back on such a policy would be enhanced by
a feeling on the part of the representatives of the public that the
work I had done must be worthy of having some pains taken to secure
its continuance in the same spirit.

I do not believe that the men who conduct our own government are a
whit behind the foremost of other countries in the desire to promote
science.  If after my retirement no special measures were deemed
necessary to secure the continuance of the work in which I had been
engaged, I prefer to attribute it to adventitious circumstances rather
than to any undervaluation of scientific research by our authorities.




IX

SCIENTIFIC WASHINGTON


It is sometimes said that no man, in passing away, leaves a place
which cannot be equally well filled by another.  This is doubtless
true in all ordinary cases.  But scientific research, and scientific
affairs generally at the national capital, form an exception to many
of the rules drawn from experience in other fields.

Professor Joseph Henry, first secretary of the Smithsonian
Institution, was a man of whom it may be said, without any reflection
on men of our generation, that he held a place which has never
been filled.  I do not mean his official place, but his position
as the recognized leader and exponent of scientific interests at
the national capital.  A world-wide reputation as a scientific
investigator, exalted character and inspiring presence, broad views
of men and things, the love and esteem of all, combined to make him
the man to whom all who knew him looked for counsel and guidance
in matters affecting the interests of science.  Whether any one
could since have assumed this position, I will not venture to say;
but the fact seems to be that no one has been at the same time able
and willing to assume it.

On coming to Washington I soon became very intimate with Professor
Henry, and I do not think there was any one here to whom he set
forth his personal wishes and convictions respecting the policy
of the Smithsonian Institution and its relations to the government
more freely than he did to me.  As every point connected with the
history and policy of this establishment is of world-wide interest,
and as Professor Henry used to put some things in a different light
from that shed upon the subject by current publications, I shall
mention a few points that might otherwise be overlooked.

It has always seemed to me that a deep mystery enshrouded the act
of Smithson in devising his fortune as he did.  That an Englishman,
whose connections and associations were entirely with the intellectual
classes,--who had never, so far as is known, a single American
connection, or the slightest inclination toward democracy,--should,
in the intellectual condition of our country during the early
years of the century, have chosen its government as his trustee
for the foundation of a scientific institution, does of itself seem
singular enough.  What seems yet more singular is that no instructions
whatever were given in his will or found in his papers beyond the
comprehensive one "to found an institution at Washington to be
called the Smithsonian Institution for the increase and diffusion
of knowledge among men."  No plan of the institution, no scrap
of paper which might assist in the interpretation of the mandate,
was ever discovered.  Not a word respecting his intention was ever
known to have been uttered.  Only a single remark was ever recorded
which indicated that he had anything unusual in view.  He did at one
time say, "My name shall live in the memory of men when the titles
of the Northumberlands and the Percys are extinct and forgotten."

One result of this failure to indicate a plan for the institution was
that, when the government received the money, Congress was at a loss
what to do with it.  Some ten years were spent in discussing schemes
of various kinds, among them that of declining the gift altogether.
Then it was decided that the institution should be governed by a
Board of Regents, who should elect a secretary as their executive
officer and the administrator of the institution.  The latter was to
include a library, a museum, and a gallery of art.  The plans for
the fine structure, so well known to every visitor to the capital,
were prepared, the building was started, the regents organized,
and Professor Henry made secretary.

We might almost say that Henry was opposed to every special function
assigned to the institution by the organic law.  He did not agree
with me as to any mystery surrounding the intentions of the founder.
To him they were perfectly clear.  Smithson was a scientific
investigator; and the increase and diffusion of knowledge among men
could be best promoted on the lines that he desired, by scientific
investigation and the publication of scientific researches.  For this
purpose a great building was not necessary, and he regretted all the
money spent on it.  The library, museum, and gallery of art would
be of only local advantage, whereas "diffusion among men" implied
all men, whether they could visit Washington or not.  It was clearly
the business of the government to supply purely local facilities for
study and research, and the endowment of Smithson should not be used
for such a purpose.

His opposition to the building tinged the whole course of his thought.
I doubt whether he was ever called upon by founders of institutions
of any sort for counsel without his warning them to beware of spending
their money in bricks and mortar.  The building being already started
before he took charge, and the three other objects being sanctioned
by law, he was, of course, hampered in carrying out his views.
But he did his utmost to reduce to a minimum the amount of the fund
that should be devoted to the objects specified.

This policy brought on the most animated contest in the history
of the institution.  It was essential that his most influential
assistants should share his views or at least not thwart them.  This,
he found, was not the case.  The librarian, Mr. C. C. Jewett, an able
and accomplished man in the line of his profession, was desirous of
collecting one of the finest scientific libraries.  A contest arose,
to which Professor Henry put an end by the bold course of removing
the librarian from office.  Mr. Jewett denied his power to do this,
and the question came before the board of regents.  The majority of
these voted that the secretary had the power to remove his assistants.
Among the minority was Rufus Choate, who was so strongly opposed to
the action that he emphasized his protest against it by resigning
from the board.

A question of legal interpretation came in to make the situation
yet more difficult.  The regents had resolved that, after the
completion of the building, one half the income should be devoted
to those objects which Professor Henry considered most appropriate.
Meanwhile there was no limit to the amount that might be appropriated
to these objects, but Mr. Jewett and other heads of departments
wished to apply the rule from the beginning.  Henry refused to do so,
and looked with entire satisfaction on the slowness of completion
of what was, in his eyes, an undesirable building.

It must be admitted that there was one point which Professor
Henry either failed to appreciate, or perhaps thought unworthy
of consideration.  This is, the strong hold on the minds of men
which an institution is able to secure through the agency of an
imposing building.  Saying nothing of the artistic and educational
value of a beautiful piece of architecture, it would seem that such
a structure has a peculiar power of impressing the minds of men with
the importance of the object to which it is devoted, or of the work
going on within it.  Had Professor Henry been allowed to perform
all the functions of the Smithsonian Institution in a moderate-sized
hired house, as he felt himself abundantly able to do, I have very
serious doubts whether it would have acquired its present celebrity
and gained its present high place in the estimation of the public.

In the winter of 1865 the institution suffered an irreparable
loss by a conflagration which destroyed the central portion of
the building.  At that time the gallery of art had been confined to
a collection of portraits of Indians by Stanley.  This collection
was entirely destroyed.  The library, being at one end, remained
intact.  The lecture room, where courses of scientific lectures
had been delivered by eminent men of science, was also destroyed.
This event gave Professor Henry an opportunity of taking a long
step in the direction he desired.  He induced Congress to take the
Smithsonian library on deposit as a part of its own, and thus relieve
the institution of the cost of supporting this branch.

The Corcoran Art Gallery had been founded in the mean time, and
relieved the institution of all necessity for supporting a gallery
of art.  He would gladly have seen the National Museum made a separate
institution, and the Smithsonian building purchased by the government
for its use, but he found no chance of carrying this out.

After the death of Professor Henry the Institution grew rapidly
into a position in which it might almost claim to be a scientific
department of the government.  The National Museum, remaining under
its administration, was greatly enlarged, and one of its ramifications
was extended into the National Zoölogical Park.  The studies of
Indian ethnology, begun by Major J. W. Powell, grew into the Bureau
of Ethnology.  The Astrophysical Observatory was established, in
which Professor Langley has continued his epoch-making work on the
sun's radiant heat with his wonderful bolometer, an instrument of
his own invention.

Before he was appointed to succeed Professor Henry, Professor Baird
was serving as United States Fish Commissioner, and continued to fill
this office, without other salary than that paid by the Smithsonian
Institution.  The economic importance of the work done and still
carried on by this commission is too well known to need a statement.
About the time of Baird's death, the work of the commission was
separated from that of the Institution by providing a salary for
the commissioner.

We have here a great extension of the idea of an institution for
scientific publications and research.  I recall once suggesting
to Professor Baird the question whether the utilization of the
institution founded by Smithson for carrying on and promoting such
government work as that of the National Museum was really the right
thing to do.  He replied, "It is not a case of using the Smithsonian
fund for government work, but of the government making appropriations
for the work of the Smithsonian Institution."  Between the two sides
of the question thus presented,--one emphasizing the honor done to
Smithson by expanding the institution which bears his name, and the
other aiming solely at the best administration of the fund which we
hold in trust for him,--I do not pretend to decide.


On the academic side of social life in Washington, the numerous
associations of alumni of colleges and universities hold a prominent
place.  One of the earliest of these was that of Yale, which has held
an annual banquet every year, at least since 1877, when I first became
a member.  Its membership at this time included Mr. W. M. Evarts, then
Secretary of State, Chief Justice Waite, Senator Dawes, and a number
of other men prominent in political life.  The most attractive speaker
was Mr. Evarts, and the fact that his views of education were somewhat
conservative added much to the interest of his speeches.  He generally
had something to say in favor of the system of a prescribed curriculum
in liberal education, which was then considered as quite antiquated.
When President Dwight, shortly after his accession to office, visited
the capital to explain the modernizing of the Yale educational system,
he told the alumni that the college now offered ninety-five courses to
undergraduates.  Evarts congratulated the coming students on sitting
at a banquet table where they had their choice of ninety-five courses
of intellectual aliment.

Perhaps the strongest testimonial of the interest attached to these
reunions was unconsciously given by President Hayes.  He had received
an honorary degree from Yale, and I chanced to be on the committee
which called to invite him to the next banquet.  He pleaded, as I
suppose Presidents always do, the multiplicity of his engagements,
but finally said,--

"Well, gentlemen, I will come, but it must be on two well-understood
conditions.  In the first place, I must not be called to my feet.
You must not expect a speech of me.  The second condition is, I must
be allowed to leave punctually at ten o'clock."

"We regret your conditions, Mr. President," was the reply, "but must,
of course, accede to them, if you insist."

He came to the banquet, he made a speech,--a very good, and not a
very short one,--and he remained, an interested hearer, until nearly
two o'clock in the morning.

In recent years I cannot avoid a feeling that a change has come over
the spirit of such associations.  One might gather the impression
that the apothegm of Sir William Hamilton needed a slight amendment.

    On earth is nothing great but Man,
    In Man is nothing great but Mind.

Strike out the last word, and insert "Muscle."  The reader will
please not misinterpret this remark.  I admire the physically
perfect man, loving everything out of doors, and animated by the
spirit that takes him through polar snows and over mountain tops.
But I do not feel that mere muscular practice during a few years of
college life really fosters this spirit.


Among the former institutions of Washington of which the memory is
worth preserving, was the Scientific Club.  This was one of those
small groups, more common in other cities than in Washington, of men
interested in some field of thought, who meet at brief intervals at
one another's houses, perhaps listen to a paper, and wind up with
a supper.  When or how the Washington Club originated, I do not know,
but it was probably sometime during the fifties.  Its membership seems
to have been rather ill defined, for, although I have always been
regarded as a member, and am mentioned in McCulloch's book as such,
[1] I do not think I ever received any formal notice of election.
The club was not exclusively scientific, but included in its list the
leading men who were supposed to be interested in scientific matters,
and whose company was pleasant to the others.  Mr. McCulloch himself,
General Sherman, and Chief Justice Chase are examples of the members
of the club who were of this class.

It was at the club meetings that I made the acquaintance of General
Sherman.  His strong characteristics were as clearly seen at these
evening gatherings as in a military campaign.  His restlessness
was such that he found it hard to sit still, especially in his
own house, two minutes at a time.  His terse sentences, leaving
no doubt in the mind of the hearer as to what he meant, always
had the same snap.  One of his military letters is worth reviving.
When he was carrying on his campaign in Georgia against Hood, the
latter was anxious that the war should damage general commercial
interests as little as possible; so he sent General Sherman a letter
setting forth the terms and conditions on which he, Hood, would
refrain from burning the cotton in his line of march, but leave it
behind,--at as great length and with as much detail as if it were
a treaty of peace between two nations.  Sherman's reply was couched
in a single sentence: "I hope you will burn all the cotton you can,
for all you don't burn I will."  When he introduced two people,
he did not simply mention their names, but told who each one was.
In introducing the adjutant-general to another officer who had just
come into Washington, he added, "You know his signature."

Mr. McCulloch, who succeeded Mr. Chase as Secretary of the Treasury,
was my beau idéal of an administrator.  In his personal make-up,
he was as completely the opposite of General Sherman as a man
well could be.  Deliberate, impassive, heavy of build, slow in
physical movement, he would have been supposed, at first sight,
a man who would take life easy, and concern himself as little
as possible about public affairs.  But, after all, there is a
quality in the head of a great department which is quite distinct
from sprightliness, and that is wisdom.  This he possessed in the
highest degree.  The impress which he made on our fiscal system was
not the product of what looked like energetic personal action, but
of a careful study of the prevailing conditions of public opinion,
and of the means at his disposal for keeping the movement of things
in the right direction.  His policy was what is sometimes claimed,
and correctly, I believe, to embody the highest administrative wisdom:
that of doing nothing himself that he could get others to do for him.
In this way all his energies could be devoted to his proper work,
that of getting the best men in office, and of devising measures
from time to time calculated to carry the government along the lines
which he judged to be best for the public interests.

The name of another attendant at the meetings of the club has from
time to time excited interest because of its connection with a
fundamental principle of evolutionary astronomy.  This principle,
which looks paradoxical enough, is that up to a certain stage,
as a star loses heat by radiation into space, its temperature
becomes higher.  It is now known as Lane's Law.  Some curiosity
as to its origin, as well as the personality of its author, has
sometimes been expressed.  As the story has never been printed,
I ask leave to tell it.

Among the attendants at the meetings of the Scientific Club was
an odd-looking and odd-mannered little man, rather intellectual in
appearance, who listened attentively to what others said, but who,
so far as I noticed, never said a word himself.  Up to the time
of which I am speaking, I did not even know his name, as there was
nothing but his oddity to excite any interest in him.

One evening about the year 1867, the club met, as it not
infrequently did, at the home of Mr. McCulloch.  After the
meeting Mr. W. B. Taylor, afterward connected with the Smithsonian
Institution in an editorial capacity, accompanied by the little man,
set out to walk to his home, which I believe was somewhere near the
Smithsonian grounds.  At any rate, I joined them in their walk,
which led through these grounds.  A few days previous there had
appeared in the "Reader," an English weekly periodical having a
scientific character, an article describing a new theory of the sun.
The view maintained was that the sun was not a molten liquid, as had
generally been supposed up to that time, but a mass of incandescent
gas, perhaps condensed at its outer surface, so as to form a sort of
immense bubble.  I had never before heard of the theory, but it was
so plausible that there could be no difficulty in accepting it.  So,
as we wended our way through the Smithsonian grounds, I explained the
theory to my companions in that _ex cathedra_ style which one is apt
to assume in setting forth a new idea to people who know little or
nothing of the subject.  My talk was mainly designed for Mr. Taylor,
because I did not suppose the little man would take any interest
in it.  I was, therefore, much astonished when, at a certain point,
he challenged, in quite a decisive tone, the correctness of one of
my propositions.  In a rather more modest way, I tried to maintain
my ground, but was quite silenced by the little man informing us that
he had investigated the whole subject, and found so and so--different
from what I had been laying down.

I immediately stepped down from the pontifical chair, and asked the
little man to occupy it and tell us more about the matter, which
he did.  Whether the theorem to which I have alluded was included
in his statement, I do not recall.  If it was not, he told me about
it subsequently, and spoke of a paper he had published, or was about
to publish, in the "American Journal of Science."  I find that this
paper appeared in Volume L. in 1870.

Naturally I cultivated the acquaintance of such a man.  His name
was J. Homer Lane.  He was quite alone in the world, having neither
family nor near relative, so far as any one knew.  He had formerly
been an examiner or something similar in the Patent Office, but
under the system which prevailed in those days, a man with no more
political influence than he had was very liable to lose his position,
as he actually did.  He lived in a good deal such a habitation and
surroundings as men like Johnson and Goldsmith lived in in their time.
If his home was not exactly a garret, it came as near it as a lodging
of the present day ever does.

After the paper in question appeared, I called Mr. Lane's attention
to the fact that I did not find any statement of the theorem which
he had mentioned to me to be contained in it.  He admitted that it
was contained in it only impliedly, and proceeded to give me a very
brief and simple demonstration.

So the matter stood, until the centennial year, 1876, when Sir
William Thomson paid a visit to this country.  I passed a very
pleasant evening with him at the Smithsonian Institution, engaged
in a discussion, some points of which he afterwards mentioned in
an address to the British Association.  Among other matters, I
mentioned this law, originating with Mr. J. Homer Lane.  He did not
think it could be well founded, and when I attempted to reproduce
Mr. Lane's verbal demonstration, I found myself unable to do so.
I told him I felt quite sure about the matter, and would write to
him on the subject.  When I again met Mr. Lane, I told him of my
difficulty and asked him to repeat the demonstration.  He did so
at once, and I sent it off to Sir William.  The latter immediately
accepted the result, and published a paper on the subject, in which
the theorem was made public for the first time.

It is very singular that a man of such acuteness never achieved
anything else of significance.  He was at my station on one occasion
when a total eclipse of the sun was to be observed, and made a report
on what he saw.  At the same time he called my attention to a slight
source of error with which photographs of the transit of Venus might
be affected.  The idea was a very ingenious one, and was published
in due course.

Altogether, the picture of his life and death remains in my memory
as a sad one, the brightest gleam being the fact that he was elected
a member of the National Academy of Sciences, which must have been
to him a very grateful recognition of his work on the part of his
scientific associates.  When he died, his funeral was attended only
by a few of his fellow members of the academy.  Altogether, I feel
it eminently appropriate that his name should be perpetuated by the
theorem of which I have spoken.


If the National Academy of Sciences has not proved as influential a
body as such an academy should, it has still taken such a place in
science, and rendered services of such importance to the government,
that the circumstances connected with its origin are of permanent
historic interest.  As the writer was not a charter member, he cannot
claim to have been "in at the birth," though he became, from time to
time, a repository of desultory information on the subject.  There is
abundant internal and circumstantial evidence that Dr. B. A. Gould,
although his name has, so far as I am aware, never been mentioned
in this connection, was a leading spirit in the first organization.
On the other hand, curiously enough, Professor Henry was not.  I was
quite satisfied that Bache took an active part, but Henry assured me
that he could not believe this, because he was so intimate with Bache
that, had the latter known anything of the matter, he would surely
have consulted him.  Some recent light is thrown on the subject
by letters of Rear-Admiral Charles H. Davis, found in his "Life,"
as published by his son.  Everything was carried on in the greatest
secrecy, until the bill chartering the body was introduced by Senator
Henry Wilson of Massachusetts.  Fifty charter members were named,
and this number was fixed as the permanent limit to the membership.
The list did not include either George P. Bond, director of the
Harvard Observatory, perhaps the foremost American astronomer of the
time in charge of an observatory, nor Dr. John W. Draper.  Yet the
total membership in the section of astronomy and kindred sciences was
very large.  A story to which I give credence was that the original
list, as handed to Senator Wilson, did not include the name of
William B. Rogers, who was then founding the Institute of Technology.
The senator made it a condition that room for Rogers should be found,
and his wish was acceded to.  It is of interest that the man thus
added to the academy by a senator afterward became its President,
and proved as able and popular a presiding officer as it ever had.

The governmental importance of the academy arose from the fact
that its charter made it the scientific adviser of the government,
by providing that it should "investigate, examine, experiment,
and report upon any subject of science or art" whenever called
upon by any department of the government.  In this respect it was
intended to perform the same valuable functions for the government
that are expected of the national scientific academies or societies
of foreign countries.

The academy was empowered to make its own constitution.  That first
adopted was sufficiently rigid and complex.  Following the example of
European bodies of the same sort, it was divided into two classes,
one of mathematical and physical, the other of natural science.
Each of these classes was divided into sections.  A very elaborate
system of procedure for the choice of new members was provided.
Any member absent from four consecutive stated meetings of the
academy had his name stricken from the roll unless he communicated
a valid reason for his absence.  Notwithstanding this requirement,
the academy had no funds to defray the traveling expenses of members,
nor did the government ever appropriate money for this purpose.

For seven years it became increasingly doubtful whether the
organization would not be abandoned.  Several of the most eminent
members took no interest whatever in the academy,--did not attend
the meetings, but did tender their resignations, which, however,
were not accepted.  This went on at such a rate that, in 1870,
to avoid a threatened dissolution, a radical change was made in
the constitution.  Congress was asked to remove the restriction upon
the number of members, which it promptly did.  Classes and sections
were entirely abandoned.  The members formed but a single body.
The method of election was simplified,--too much simplified, in fact.

The election of new members is, perhaps, the most difficult and
delicate function of such an organization.  It is one which cannot be
performed to public satisfaction, nor without making many mistakes;
and the avoidance of the latter is vastly more difficult when the
members are so widely separated and have little opportunity to discuss
in advance the merits of the men from whom a selection is to be made.
An ideal selection cannot be made until after a man is dead, so that
his work can be summed up; but I think it may fairly be said that,
on the whole, the selections have been as good as could be expected
under the conditions.

Notwithstanding the indifference of the government to the possible
benefits that the academy might render it, it has--in addition to
numerous reports on minor subjects--made two of capital importance
to the public welfare.  One of these was the planning of the United
States Geological Survey, the other the organization of a forestry
system for the United States.

During the years 1870-77, besides several temporary surveys or
expeditions which had from time to time been conducted under the
auspices of the government, there were growing up two permanent
surveys of the territories.  One of these was the Geographical
Survey of territories west of the 100th meridian, under the Chief
of Engineers of the Army; the other was the Geological Survey of
the territories under the Interior Department, of which the chief
was Professor F. V. Hayden.

The methods adopted by the two chiefs to gain the approval of the
public and the favoring smiles of Congress were certainly very
different.  Wheeler's efforts were made altogether by official
methods and through official channels.  Hayden considered it his
duty to give the public every possible opportunity to see what he
was doing and to judge his work.  His efforts were chronicled at
length in the public prints.  His summers were spent in the field,
and his winters were devoted to working up results and making every
effort to secure influence.  An attractive personality and extreme
readiness to show every visitor all that there was to be seen in his
collections, facilitated his success.  One day a friend introduced
a number of children with an expression of doubt as to the little
visitors being welcome.  "Oh, I always like to have the children
come here," he replied, "they influence their parents."  He was so
successful in his efforts that his organization grew apace, and soon
developed into the Geological Survey of the Territories.

Ostensibly the objects of the two organizations were different.
One had military requirements mainly in view, especially the mapping
of routes.  Hayden's survey was mainly in the interests of geology.
Practically, however, the two covered the same field in all points.
The military survey extended its scope by including everything
necessary for a complete geographical and geological atlas.
The geological survey was necessarily a complete topographical and
geological survey from the beginning.  Between 1870 and 1877, both
were engaged in making an atlas of Colorado, on the maps of which
were given the same topographical features and the same lines of
communication.  Parties of the two surveys mounted their theodolites
on the same mountains, and triangulated the same regions.  The Hayden
survey published a complete atlas of Colorado, probably more finely
gotten up than any atlas of a State in the Union, while the Wheeler
survey was vigorously engaged in issuing maps of the same territory.
No effort to prevent this duplication of work by making an arrangement
between the two organizations led to any result.  Neither had any
official knowledge of the work of the other.  Unofficially, the one
was dissatisfied with the political methods of the other, and claimed
that the maps which it produced were not fit for military purposes.
Hayden retorted with unofficial reflections on the geological
expertness of the engineers, and maintained that their work was
not of the best.  He got up by far the best maps; Wheeler, in the
interests of economy, was willing to sacrifice artistic appearance
to economy of production.  We thus had the curious spectacle of the
government supporting two independent surveys of the same region.
Various compromises were attempted, but they all came to nothing.
The state of things was clear enough to Congress, but the repugnance
of our national legislature to the adoption of decisive measures of
any sort for the settlement of a disputed administrative question
prevented any effective action.  Infant bureaus may quarrel with each
other and eat up the paternal substance, but the parent cannot make
up his mind to starve them outright, or even to chastise them into
a spirit of conciliation.  Unable to decide between them, Congress
for some years pursued the policy of supporting both surveys.

The credit for introducing a measure which would certainly lead to
unification is due to Mr. A. S. Hewitt, of New York, then a member
of the Committee on Appropriations.  He proposed to refer the whole
subject to the National Academy of Sciences.  His committee accepted
his view, and a clause was inserted in the Sundry Civil Bill of June
30, 1878, requiring the academy at its next meeting to take the matter
into consideration and report to Congress "as soon thereafter as may
be practicable, a plan for surveying and mapping the territory of
the United States on such general system as will, in their judgment,
secure the best results at the least possible cost."

Several of the older and more conservative members of the academy
objected that this question was not one of science or art, with
which alone the academy was competent to deal, but was a purely
administrative question which Congress should settle for itself.
They feared that the academy would be drawn into the arena of
political discussion to an extent detrimental to its future and
welfare and usefulness.  Whether the exception was or was not well
taken, it was felt that the academy, the creature of Congress, could
not join issue with the latter as to its functions, nor should an
opportunity of rendering a great service to the government be lost
for such a reason as this.

The plan reported by the academy was radical and comprehensive.
It proposed to abolish all the existing surveys of the territories
except those which, being temporary, were completing their work,
and to substitute for them a single organization which would include
the surveys of the public lands in its scope.  The interior work
of the Coast and Geodetic Survey was included in the plan, it being
proposed to transfer this bureau to the Interior Department, with its
functions so extended as to include the entire work of triangulation.

When the proposition came up in Congress at the following session,
it was vigorously fought by the Chief of Engineers of the army,
and by the General Land Office, of which the surveying functions
were practically abolished.  The Land Office carried its point,
and was eliminated from the scheme.  General Humphreys, the Chief of
Engineers, was a member of the academy, but resigned on the ground
that he could not properly remain a member while contesting the
recommendations of the body.  But the academy refused to accept the
resignation, on the very proper ground that no obligation was imposed
on the members to support the views of the academy, besides which,
the work of the latter in the whole matter was terminated when its
report was presented to Congress.

Although this was true of the academy, it was not true of the
individual members who had taken part in constructing the scheme.
They were naturally desirous of seeing the plan made a success, and,
in the face of such vigorous opposition, this required constant
attention.  A dexterous movement was that of getting the measure
transferred from one appropriation bill to another when it passed
over to the Senate.  The measure at length became a law, and thus
was established the Geological Survey of the United States, which
was to be governed by a Director, appointed by the President, by
and with the advice and consent of the Senate.

Then, on March 4, 1879, an important question arose.  The right man
must be placed at the head of the new bureau.  Who is he?  At first
there seemed to be but one voice on the subject, Professor Hayden had
taken the greatest pains to make known the work of his survey, not
only to Congress, but to every scientific society, small and great,
the world over.  Many of these had bestowed their approbation upon it
by electing its director to honorary membership.  It has been said,
I do not know how truly, that the number of these testimonials
exceeded that received by any other scientific man in America.
If this were so, they would have to be counted, not weighed.  It was,
therefore, not surprising that two thirds of the members of Congress
were said to have sent a recommendation to the President for the
appointment of so able and successful a man to the new position.
The powerful backing of so respectable a citizen as Hon. J. D. Cox,
formerly Secretary of the Interior, was also heartily proffered.
To these forces were added that of a certain number of geologists,
though few or none of them were leaders in the science.  Had it not
been for a private intimation conveyed to Secretary Schurz that the
scientific men interested might have something to say on the subject,
Hayden might have been appointed at the very moment the bill was
signed by the President.

Notwithstanding all of Hayden's merits as the energetic head of a
survey, the leaders in the movement considered that Mr. Clarence King
was the better qualified for the duties of the new position.  It is
not unlikely that a preference for a different method of influencing
Congress than that which I have described, was one of the reasons in
favor of Mr. King.  He was a man of charming personality and great
literary ability.  Some one said of him that he could make a more
interesting story out of what he saw during a ride in a street car
than most men could with the best material at their disposal.  His
"Mountaineering in the Sierra Nevadas" was as interesting an account
of Western exploration as has ever been published.  I understand it
was suppressed by the author because some of the characters described
in it were much hurt by finding themselves painted in the book.

Hopeless though the contest might have seemed, an effort was made
by three or four of the men most interested to secure Mr. King's
appointment.  If I wanted to show the fallacy of the common impression
that scientific men are not fitted for practical politics, I could
not do it better than by giving the internal history of the movement.
This I shall attempt only in the briefest way.  The movers in the
matter divided up the work, did what they could in the daytime,
and met at night at Wormley's Hotel to compare notes, ascertain the
effect of every shot, and decide where the next one should be fired.
As all the parties concerned in the matter have now passed off the
stage, I shall venture to mention one of these shots.  One eminent
geologist, whose support was known to be available, had not been
called in, because an impression had been formed that President
Hayes would not be willing to consider favorably what he might say.
After the matter had been discussed at one or two meetings, one
of the party proposed to sound the President on the subject at his
next interview.  So, when the occasion arose, he gently introduced
the name of the gentleman.

"What view does he take?" inquired the President.

"I think he will be favorable to Mr. King," was the reply; "but
would you give great weight to his opinion?"

"I would give great weight to it, very great weight, indeed," was
the reply.

This expression was too decided in its tone to leave any doubt,
and the geologist in question was on his way to Washington as soon
as electricity could tell him that he was wanted.  When the time
finally came for a decision, the President asked Secretary Schurz
for his opinion.  Both agreed that King was the man, and he was
duly appointed.

The new administration was eminently successful.  But King was
not fond of administrative work, and resigned the position at the
end of a year or so.  He was succeeded by John W. Powell, under
whom the survey grew with a rapidity which no one had anticipated.
As originally organized, the survey was one of the territories only,
but the question whether it should not be extended to the States as
well, and prepare a topographical atlas of the whole country, was
soon mooted, and decided by Congress in the affirmative.  For this
extension, however, the original organizers of the survey were in
no way responsible.  It was the act of Congress, pure and simple.

If the success of an organization is to be measured by the public
support which it has commanded, by the extension of its work and
influence, and by the gradual dying out of all opposition, it must be
admitted that the plan of the academy was a brilliant success.  It is
true that a serious crisis had once to be met.  While Mr. Cleveland
was governor of New York, his experience with the survey of that
State had led him to distrust the methods on which the surveys
of the United States were being conducted.  This distrust seems
to have pervaded the various heads of the departments under his
administration, and led to serious charges against the conduct of
both the Coast and Geological surveys.  An unfavorable report upon
the administration of the former was made by a committee especially
appointed by the Secretary of the Treasury, and led to the resignation
of its superintendent.  But, in the case of the Geological Survey,
the attacks were mostly conducted by the newspapers.  At length,
Director Powell asked permission of Secretary Lamar to write him a
letter in reply.  His answers were so sweeping, and so conclusive
on every point, that nothing more was heard of the criticisms.

The second great work of the academy for the government was that
of devising a forestry system for the United States.  The immediate
occasion for action in this direction was stated by Secretary Hoke
Smith to be the "inadequacy and confusion of existing laws relating
to the public timber lands and consequent absence of an intelligent
policy in their administration, resulting in such conditions as may,
if not speedily stopped, prevent the proper development of a large
part of our country."

Even more than in the case of the Geological Survey might this
work seem to be one of administration rather than of science.
But granting that such was the case, the academy commanded great
advantages in taking up the subject.  The commission which it formed
devoted more than a year to the study, not only of the conditions
in our own country, but of the various policies adopted by foreign
countries, especially Germany, and their results.  As in the case
of the Geological Survey, a radically new and very complete system
of forestry administration was proposed.  Interests having other
objects than the public good were as completely ignored as they had
been before.

The soundness of the conclusions reached by the Academy Commission
were challenged by men wielding great political power in their
respective States.  For a time it was feared that the academy would
suffer rather than gain in public opinion by the report it had made.
But the moral force behind it was such that, in the long run, some of
the severest critics saw their error, and a plan was adopted which,
though differing in many details from that proposed, was, in the main,
based on the conclusion of the commission.  The Interior department,
the Geological Survey, and the Department of Agriculture all have
their part in the work.

Notwithstanding these signal demonstrations of the valuable service
which the academy may render to the government, the latter has done
nothing for it.  The immediate influence of the leading scientific men
in public affairs has perhaps been diminished as much in one direction
as it has been increased in another by the official character of
the organization.  The very fact that the members of the academy
belong to a body which is, officially, the scientific adviser of
the government, prevents them from coming forward to exercise that
individual influence which they might exercise were no such body
in existence.

The academy has not even a place of meeting, nor is a repository
for its property and records provided for it.  Although it holds
in trust large sums which have been bequeathed from time to time by
its members for promoting scientific investigation, and is, in this
way, rendering an important service to the progress of knowledge,
it has practically no income of its own except the contributions of
its own members, nearly all of whom are in the position described
by the elder Agassiz, of having "no time to make money."

Among the men who have filled the office of president of the academy,
Professor O. C. Marsh was perhaps the one whose activity covered the
widest field.  Though long well known in scientific circles, he first
came into public prominence by his exposure of the frauds practiced
by contractors in furnishing supplies for the Indians.  This business
had fallen into the hands of a small ring of contractors known as the
"Indian ring," who knew the ropes so well that they could bid below
any competitor and yet manage things so as to gain a handsome profit
out of the contracts.  In the course of his explorations Marsh took
pains to investigate the whole matter, and published his conclusions
first in the New York "Tribune," and then more fully in pamphlet
form, taking care to have public attention called to the subject so
widely that the authorities would have to notice it.  In doing so,
Mr. Delano, Secretary of the Interior, spoke of them as charges made
by "a Mr. Marsh."  This method of designating such a man was made
effective use of by Mr. Delano's opponents in the case.

Although the investigation which followed did not elicit all the
facts, it had the result of calling the attention of succeeding
Secretaries of the Interior to the necessity of keeping the best
outlook on the administration of Indian affairs.  What I believe to
have been the final downfall of the ring was not brought about until
Cleveland's first administration.  Then it happened in this way.
Mr. Lamar, the Secretary of the Interior, was sharply on the lookout
for frauds of every kind.  As usual, the lowest bid for a certain
kind of blanket had been accepted, and the Secretary was determined
to see whether the articles furnished actually corresponded with
the requirements of the contract.  It chanced that he had as his
appointment clerk Mr. J. J. S. Hassler, a former manufacturer of
woolen goods.  Mr. Hassler was put on the board to inspect the
supplies, and found that the blankets, although to all ordinary
appearance of the kind and quality required, were really of a much
inferior and cheaper material.  The result was the enforced failure
of the contractor, and, I believe, the end of the Indian ring.

Marsh's explorations in search of fossil remains of the animals which
once roamed over the western parts of our continent were attended
by adventures of great interest, which he long had the intention of
collecting and publishing in book form.  Unfortunately, he never did
it, nor, so far as I am aware, has any connected narrative of his
adventures ever appeared in print.  This is more to be regretted,
because they belong to a state of things which is rapidly passing
away, leaving few records of that lifelike sort which make the most
impressive picture.

His guide during his early explorations was a character who
has since become celebrated in America and Europe by the vivid
representations of the "Wild West" with which he has amused and
instructed the dwellers on two continents.  Marsh was on his way to
explore the region in the Rocky Mountains where he was to find the
fossils which have since made his work most celebrated.  The guide
was burning with curiosity as to the object of the expedition.
One night over the campfire he drew his chief into a conversation on
the subject.  The latter told him that there was once a time when the
Rocky Mountains did not exist, and that part of the continent was a
level plain.  In the course of long ages mountains rose, and animals
ran over them.  Then the mountains split open; the animals died and
left their bones in the clefts.  The object of his expedition was
now to search for some of these bones.

The bones were duly discovered, and it was not many years thereafter
before the Wild West Exhibition was seen in the principal Eastern
cities.  When it visited New Haven, its conductor naturally renewed
the acquaintance of his former patron and supporter.

"Do you remember, professor," said he, "our talk as we were going on
your expedition to the Rockies,--how you told me about the mountains
rising up and being split open and the bones of animals being lost
in there, and how you were going to get them?"

"Oh, yes," said the other, "I remember it very well."

"Well, professor, do you know, when you told me all that I r'ally
thought you was puttin' up a job on me."

The result was a friendship between the two men, which continued
during Marsh's whole life.  When the one felt that he ought no longer
to spend all the money he earned, he consulted Marsh on the subject of
"salting it down," and doubtless got good advice.

As an exposer of humbugs Marsh took a prominent place.  One of these
related to the so-called "Cardiff Giant."  Sometime in 1869 the
newspapers announced the discovery in northern New York, near the
Canadian border, of an extraordinary fossil man, or colossal statue,
people were not sure which, eight or ten feet high.  It was found
several feet below the ground while digging a well.  Men of some
scientific repute, including even one so eminent as Professor James
Hall, had endorsed the genuineness of the find, and, on the strength
of this, it was taken around to show the public.  In the course of
a journey through New York State, Marsh happened to pass through
the town where the object was on exhibition.  His train stopped
forty minutes for dinner, which would give him time to drive to the
place and back, and leave a margin of about fifteen minutes for an
examination of the statue.  Hardly more than a glance was necessary
to show its fraudulent character.  Inside the ears the marks of a
chisel were still plainly visible, showing that the statue had been
newly cut.  One of the most curious features was that the stone
had not been large enough to make the complete statue, so that
the surface was, in one place, still in the rough.  The object had
been found in wet ground.  Its material was sulphate of lime, the
slight solubility of which would have been sufficient to make it
dissolve entirely away in the course of centuries.  The absence of
any degradation showed that the thing was comparatively new.  On the
strength of this, Marsh promptly denounced the affair as a humbug.
Only a feeble defense was made for it, and, a year or two later, the
whole story came out.  It had been designed and executed somewhere in
the Northwest, transported to the place where discovered, and buried,
to be afterward dug up and reported as a prehistoric wonder.

Only a few years ago the writer had an opportunity of seeing
with what wonderful ease intelligent men can be imposed upon by
these artificial antiquities.  The would-be exhibitor of a fossil
woman, found I know not where, appeared in Washington.  He had not
discovered the fossil himself, but had purchased it for some such
sum as $100, on the assurance of its genuine character.  He seems,
however, to have had some misgivings on the subject, and, being an
honest fellow, invited some Washington scientific men to examine it
in advance of a public exhibition.  The first feature to strike the
critical observer was that the arms of the fossil were crossed over
the breast in the most approved undertaker's fashion, showing that
if the woman had ever existed, she had devoted her dying moments to
arranging a pose for the approval of posterity.  Little more than a
glance was necessary to show that the fossil was simply baked clay.
Yet the limbs were hard and stiff.  One of the spectators therefore
asked permission of the owner to bore with an auger into the leg and
see what was inside.  A few moments' work showed that the bone of the
leg was a bar of iron, around which clay had been moulded and baked.
I must do the crestfallen owner the justice to say that his anxiety
to convince the spectators of his own good faith in the matter far
exceeded his regret at the pecuniary loss which he had suffered.

Another amusing experience that Marsh had with a would-be fossil
arose out of the discovery here and there in Connecticut of the
fossil footprints of birds.  Shortly after a find of this kind had
been announced, a farmer drove his wagon up in front of the Peabody
Museum, called on the professor, and told him he had dug up something
curious on his farm, and he wished the professor would tell him what
it was.  He thought it looked like the footprints of a bird in a
stone, but he was not quite sure.

Marsh went out and looked at the stone.  A single glance was enough.

"Oh, I see what they are.  They are the footprints of the domestic
turkey.  And the oddest part of it is, they are all made with the
right foot."

The simple-minded countryman, in making the prints with the turkey's
foot, had overlooked the difference between the right and left foot,
and the consequent necessity of having the tracks which pertained
to the two feet alternate.


Washington is naturally a centre of information on all subjects
relating to the aboriginal tribes of America and to life on the plains
generally.  Besides the Geological Survey, the Bureau of Ethnology
has been an active factor in this line.  An official report cannot
properly illustrate life in all its aspects, and therefore should
be supplemented by the experiences of leading explorers.  This is
all the more necessary if, as seems to be the case, the peculiar
characteristics of the life in question are being replaced by those
more appropriate to civilization.  Yet the researches of the bureau in
question are not carried on in any narrow spirit, and will supply the
future student of humanity with valuable pictures of the most heroic
of all races, and yet doomed, apparently, to ultimate extinction.
I do not think I ever saw a more impressive human figure and face
than those of Chief Joseph as he stood tall, erect, and impassive,
at a President's reception in the winter of 1903.  He was attired
in all the brilliancy of his official costume; but not a muscle of
his strongly marked face betrayed the sentiments with which he must
have gazed on the shining uniforms passing before him.

SCIENTIFIC ENGLAND


My first trip to Europe, mentioned in the last chapter, was made with
my wife, when the oldest transatlantic line was still the fashionable
one.  The passenger on a Cunarder felt himself amply compensated for
poor attendance, coarse food, and bad coffee by learning from the
officers on the promenade deck how far the ships of their line were
superior to all others in strength of hull, ability of captain, and
discipline of crew.  Things have changed on both sides since then.
Although the Cunard line has completed its half century without
having lost a passenger, other lines are also carefully navigated,
and the Cunard passenger, so far as I know, fares as well as any
other.  Captain McMickan was as perfect a type of the old-fashioned
captain of the best class as I ever saw.  His face looked as if the
gentlest zephyr that had ever fanned it was an Atlantic hurricane,
and yet beamed with Hibernian good humor and friendliness.  He read
prayers so well on Sunday that a passenger assured him he was born
to be a bishop.  One day a ship of the North German Lloyd line was
seen in the offing slowly gaining on us.  A passenger called the
captain's attention to the fact that we were being left behind.
"Oh, they're very lightly built, them German ships; built to carry
German dolls and such like cargo."

In London one of the first men we met was Thomas Hughes, of Rugby
fame, who made us feel how worthy he was of the love and esteem
bestowed upon him by Americans.  He was able to make our visit
pleasant in more ways than one.  Among the men I wanted to see was
Mr. John Stuart Mill, to whom I was attracted not only by his fame
as a philosopher and the interest with which I had read his books,
but also because he was the author of an excellent pamphlet on the
Union side during our civil war.

On my expressing a desire to make Mr. Mill's acquaintance, Mr. Hughes
immediately offered to give me a note of introduction.  Mill lived at
Blackheath, which, though in an easterly direction down the Thames,
is one of the prettiest suburbs of the great metropolis.  His dwelling
was a very modest one, entered through a passage of trellis-work in a
little garden.  He was by no means the grave and distinguished-looking
man I had expected to see.  He was small in stature and rather
spare, and did not seem to have markedly intellectual features.
The cordiality of his greeting was more than I could have expected;
and he was much pleased to know that his work in moulding English
sentiment in our favor at the commencement of the civil war was so
well remembered and so highly appreciated across the Atlantic.

As a philosopher, it must be conceded that Mr. Mill lived at an
unfortunate time.  While his vigor and independence of thought led
him to break loose from the trammels of the traditional philosophy,
modern scientific generalization had not yet reached a stage favorable
to his becoming a leader in developing the new philosophy.  Still,
whatever may be the merits of his philosophic theories, I believe
that up to a quite recent time no work on scientific method appeared
worthy to displace his "System of Logic."

A feature of London life that must strongly impress the scientific
student from our country is the closeness of touch, socially as
well as officially, between the literary and scientific classes on
the one side and the governing classes on the other.  Mr. Hughes
invited us to make an evening call with him at the house of a cabinet
minister,--I think it was Mr. Goschen,--where we should find a number
of persons worth seeing.  Among those gathered in this casual way
were Mr. Gladstone, Dean Stanley, and our General Burnside, then
grown quite gray.  I had never before met General Burnside, but his
published portraits were so characteristic that the man could scarcely
have been mistaken.  The only change was in the color of his beard.
Then and later I found that a pleasant feature of these informal
"at homes," so universal in London, is that one meets so many people
he wants to see, and so few he does not want to see.

Congress had made a very liberal appropriation for observations of the
solar eclipse,--the making of which was one object of my visit,--to
be expended under the direction of Professor Peirce, superintendent
of the Coast Survey.  Peirce went over in person to take charge
of the arrangements.  He arrived in London with several members of
his party a few days before we did, and about the same time came an
independent party of my fellow astronomers from the Naval Observatory,
consisting of Professors Hall, Harkness, and Eastman.  The invasion of
their country by such an army of American astronomers quite stirred up
our English colleagues, who sorrowfully contrasted the liberality of
our government with the parsimony of their own, which had, they said,
declined to make any provision for the observations of the eclipse.
Considering that it was visible on their own side of the Atlantic,
they thought their government might take a lesson from ours.
Of course we could not help them directly; and yet I suspect that
our coming, or at least the coming of Peirce, really did help them a
great deal.  At any rate, it was a curious coincidence that no sooner
did the American invasion occur than it was semi-officially discovered
that no application of which her Majesty's government could take
cognizance had been made by the scientific authorities for a grant
of money with which to make preparations for observing the eclipse.
That the scientific authorities were not long in catching so broad
a hint as this goes without saying.  A little more of the story came
out a few days later in a very unexpected way.

In scientific England, the great social event of the year is the
annual banquet of the Royal Society, held on St. Andrew's day,
the date of the annual meeting of the society, and of the award of
its medals for distinguished work in science.  At the banquet the
scientific outlook is discussed not only by members of the society,
but by men high in political and social life.  The medalists are
toasted, if they are present; and their praises are sung, if, as is
apt to be the case with foreigners, they are absent.  First in rank
is the Copley medal, founded by Sir Godfrey Copley, a contemporary of
Newton.  This medal has been awarded annually since 1731, and is now
considered the highest honor that scientific England has to bestow.
The recipient is selected with entire impartiality as to country,
not for any special work published during the year, but in view of
the general merit of all that he has done.  Five times in its history
the medal has crossed the Atlantic.  It was awarded to Franklin in
1753, Agassiz in 1861, Dana in 1877, and J. Willard Gibbs in 1902.
The long time that elapsed between the first and the second of these
awards affords an illustration of the backwardness of scientific
research in America during the greater part of the first century of
our independence.  The year of my visit the medal was awarded to
Mr. Joule, the English physicist, for his work on the relation of
heat and energy.

I was a guest at the banquet, which was the most brilliant function
I had witnessed up to that time.  The leaders in English science
and learning sat around the table.  Her Majesty's government was
represented by Mr. Gladstone, the Premier, and Mr. Lowe, afterward
Viscount Sherbrooke, Chancellor of the Exchequer.  Both replied
to toasts.  Mr. Lowe as a speaker was perhaps a little dull, but
not so Mr. Gladstone.  There was a charm about the way in which his
talk seemed to display the inner man.  It could not be said that he
had either the dry humor of Mr. Evarts or the wit of Mr. Depew; but
these qualities were well replaced by the vivacity of his manner and
the intellectuality of his face.  He looked as if he had something
interesting he wanted to tell you; and he proceeded to tell it in
a very felicitous way as regarded both manner and language, but
without anything that savored of eloquence.  He was like Carl Schurz
in talking as if he wanted to inform you, and not because he wanted
you to see what a fine speaker he was.  With this he impressed one
as having a perfect command of his subject in all its bearings.

I did not for a moment suppose that the Premier of England could have
taken any personal interest in the matter of the eclipse.  Great,
therefore, was my surprise when, in speaking of the relations of
the government to science, he began to talk about the coming event.
I quote a passage from memory, after twenty-seven years: "I had the
pleasure of a visit, a few days since, from a very distinguished
American professor, Professor Peirce of Harvard.  In the course of
the interview, the learned gentleman expressed his regret that her
Majesty's government had declined to take any measures to promote
observations of the coming eclipse of the sun by British astronomers.
I replied that I was not aware that the government had declined to
take such measures.  Indeed, I went further, and assured him that any
application from our astronomers for aid in making these observations
would receive respectful consideration."  I felt that there might
be room for some suspicion that this visit of Professor Peirce was a
not unimportant factor in the changed position of affairs as regarded
British observations of the eclipse.

Not only the scene I have described, but subsequent experience, has
impressed me with the high appreciation in which the best scientific
work is held by the leading countries of Europe, especially England
and France, as if the prosecution were something of national
importance which men of the highest rank thought it an honor to
take part in.  The Marquis of Salisbury, in an interval between two
terms of service as Premier of England, presided over the British
Association for the Advancement of Science, and delivered an address
showing a wide and careful study of the generalizations of modern
science.

In France, also, one great glory of the nation is felt to be the
works of its scientific and learned men of the past and present.
Membership of one of the five academies of the Institute of France
is counted among the highest honors to which a Frenchman can aspire.
Most remarkable, too, is the extent to which other considerations than
that of merit are set aside in selecting candidates for this honor.
Quite recently a man was elected a member of the Academy of Sciences
who was without either university or official position, and earned a
modest subsistence as a collaborator of the "Revue des Deux Mondes."
But he had found time to make investigations in mathematical astronomy
of such merit that he was considered to have fairly earned this
distinction, and the modesty of his social position did not lie in
his way.


At the time of this visit Lister was an eminent member of the medical
profession, but had not, so far as I am aware, been recognized as
one who was to render incalculable service to suffering humanity.
From a professional point of view there are no two walks in life
having fewer points of contact than those of the surgeon and the
astronomer.  It is therefore a remarkable example of the closeness
of touch among eminent Englishmen in every walk of life, that, in
subsequent visits, I was repeatedly thrown into contact with one
who may fairly be recommended as among the greatest benefactors of
the human race that the nineteenth century has given us.  This was
partly, but not wholly, due to his being, for several years, the
president of the Royal Society.  I would willingly say much more,
but I am unable to write authoritatively upon the life and work of
such a man, and must leave gossip to the daily press.

For the visiting astronomer at London scarcely a place in London has
more attractions than the modest little observatory and dwelling house
on Upper Tulse Hill, in which Sir William Huggins has done so much
to develop the spectroscopy of the fixed stars.  The owner of this
charming place was a pioneer in the application of the spectroscope
to the analysis of the light of the heavenly bodies, and after nearly
forty years of work in this field, is still pursuing his researches.
The charm of sentiment is added to the cold atmosphere of science by
the collaboration of Lady Huggins.  Almost at the beginning of his
work Mr. Huggins, analyzing the light of the great nebula of Orion,
showed that it must proceed from a mass of gas, and not from solid
matter, thus making the greatest step possible in our knowledge of
these objects.  He was also the first to make actual measures of the
motions of bright stars to or from our system by observing the wave
length of the rays of light which they absorbed.  Quite recently an
illustrated account of his observatory and its work has appeared in
a splendid folio volume, in which the rigor of science is tempered
with a gentle infusion of art which tempts even the non-scientific
reader to linger over its pages.

In England, the career of Professor Cayley affords an example of the
spirit that impels a scientific worker of the highest class, and of
the extent to which an enlightened community may honor him for what
he is doing.  One of the creators of modern mathematics, he never
had any ambition beyond the prosecution of his favorite science.
I first met him at a dinner of the Astronomical Society Club.
As the guests were taking off their wraps and assembling in the
anteroom, I noticed, with some surprise, that one whom I supposed
to be an attendant was talking with them on easy terms.  A moment
later the supposed attendant was introduced as Professor Cayley.
His garb set off the seeming haggardness of his keen features so
effectively that I thought him either broken down in health or just
recovering from some protracted illness.  The unspoken words on
my lips were, "Why, Professor Cayley, what has happened to you?"
Being now in the confessional, I must own that I did not, at the
moment, recognize the marked intellectuality of a very striking face.
As a representation of a mathematician in the throes of thought,
I know nothing to equal his portrait by Dickenson, which now hangs
in the hall of Trinity College, Cambridge, and is reproduced in the
sixth volume of Cayley's collected works.  His life was that of a
man moved to investigation by an uncontrollable impulse; the only
sort of man whose work is destined to be imperishable.  Until forty
years of age he was by profession a conveyancer.  His ability was
such that he might have gained a fortune by practicing the highest
branch of English law, if his energies had not been diverted in
another direction.  The spirit in which he pursued his work may
be judged from an anecdote related by his friend and co-worker,
Sylvester, who, in speaking of Cayley's even and placid temper,
told me that he had never seen him ruffled but once.  Entering his
office one morning, intent on some new mathematical thought which
he was discussing with Sylvester, he opened the letter-box in his
door and found a bundle of papers relating to a law case which he
was asked to take up.  The interruption was too much.  He flung the
papers on the table with remarks more forcible than complimentary
concerning the person who had distracted his attention at such an
inopportune moment.  In 1863 he was made a professor at Cambridge,
where, no longer troubled with the intricacies of land tenure, he
published one investigation after another with ceaseless activity,
to the end of his life.

Among my most interesting callers was Professor John C. Adams, of
whom I have spoken as sharing with Leverrier the honor of having
computed the position of the planet Neptune before its existence
was otherwise known.  The work of the two men was prosecuted at
almost the same time, but adopting the principle that priority of
publication should be the sole basis of credit, Arago had declared
that no other name than that of Leverrier should even be mentioned
in connection with the work.  If repute was correct, Leverrier was
not distinguished for those amiable qualities that commonly mark the
man of science and learning.  His attitude toward Adams had always
been hostile.  Under these conditions chance afforded the latter
a splendid opportunity of showing his superiority to all personal
feeling.  He was president of the Royal Astronomical Society when
its annual medal was awarded to his French rival for his work in
constructing new tables of the sun and planets.  It thus became his
duty to deliver the address setting forth the reasons for the award.
He did this with a warmth of praise for Leverrier's works which
could not have been exceeded had the two men been bosom friends.

Adams's intellect was one of the keenest I ever knew.  The most
difficult problems of mathematical astronomy and the most recondite
principles that underlie the theory of the celestial motions were
to him but child's play.  His works place him among the first
mathematical astronomers of the age, and yet they do not seem to do
his ability entire justice.  Indeed, for fifteen years previous to
the time of my visit his published writings had been rather meagre.
But I believe he was justly credited with an elaborate witticism
to the following effect: "In view of the fact that the only human
being ever known to have been killed by a meteorite was a monk, we
may concede that after four hundred years the Pope's bull against
the comet has been justified by the discovery that comets are made
up of meteorites."

Those readers who know on what imperfect data men's impressions are
sometimes founded will not be surprised to learn of my impression
that an Englishman's politics could be inferred from his mental
and social make-up.  If all men are born either Aristotelians or
Platonists, then it may be supposed that all Englishmen are born
Conservatives or Liberals.

The utterances of English journalists of the Conservative party about
American affairs during and after our civil war had not impressed
me with the idea that one so unfortunate as to be born in that
party would either take much interest in meeting an American or
be capable of taking an appreciative view of scientific progress.
So confident was I of my theory that I remarked to a friend with
whom I had become somewhat intimate, that no one who knew Mr. Adams
could have much doubt that he was a Liberal in politics.

An embarrassed smile spread over the friend's features.  "You would
not make that conclusion known to Mr. Adams, I hope," said he.

"But is he not a Liberal?"

"He is not only a Conservative, but declares himself 'a Tory of
the Tories.'"

I afterward found that he fully justified his own description.
At the university, he was one of the leading opponents of those
measures which freed the academic degrees from religious tests.
He was said to have been among those who objected to Sylvester,
a Jew, receiving a degree.


I had decided to observe the eclipse at Gibraltar.  In order that
my results, if I obtained any, might be utilized in the best way, it
was necessary that the longitude of the station should be determined
by telegraph.  This had never been done for Gibraltar.  How great
the error of the supposed longitude might have been may be inferred
from the fact that a few years later, Captain F. Green of the United
States Navy found the longitude of Lisbon on the Admiralty charts
to be two miles in error.  The first arrangements I had to make
in England were directed to this end.  Considering the relation
of the world's great fortress to British maritime supremacy, it
does seem as if there were something presumptuous in the coolness
with which I went among the authorities to make arrangements for
the enterprise.  Nevertheless, the authorities permitted the work,
with a cordiality which was of itself quite sufficient to remove
any such impression, had it been entertained.  The astronomers did,
indeed, profess to feel it humiliating that the longitude of such
a place as Gibraltar should have to be determined from Greenwich by
an American.  They did not say "by a foreigner," because they always
protested against Americans looking upon themselves as such.  Still,
it would not be an English enterprise if an American carried it out.
I suspect, however, that my proceedings were not looked upon with
entire dissatisfaction even by the astronomers.  They might prove
as good a stimulant to their government in showing a little more
enterprise in that direction as the arrival of our eclipse party did.

The longitude work naturally took me to the Royal Observatory which
has made the little town of Greenwich so famous.  It is situated some
eight miles east from Charing Cross, on a hill in Greenwich Park,
with a pleasant outlook toward the Thames.  From my youth up I had
been working with its observations, and there was no institution
in the world which I had approached, or could approach, with the
interest I felt in ascending the little hill on which it is situated.
When the Calabria was once free from her wharf in New York harbor,
and on her way down the Narrows, the foremost thought was, "Off for
Europe; we shall see Greenwich!"  The day of my arrival in London
I had written to Professor Airy, and received an answer the same
evening, inviting us to visit the observatory and spend an afternoon
with him a day or two later.

I was shown around the observatory by an assistant, while my wife
was entertained by Mrs. Airy and the daughters inside the dwelling.
The family dined as soon as the day's work was over, about the middle
of the afternoon.  After the meal, we sat over a blazing fire and
discussed our impressions of London.

"What place in London interested you most?" said Airy to my wife.

"The first place I went to see was Cavendish Square."

"What was there in Cavendish Square to interest you?"

"When I was a little girl, my mother once gave me, as a birthday
present, a small volume of poems.  The first verse in the book was:--

 "'Little Ann and her mother were walking one day
    Through London's wide city so fair;
   And business obliged them to go by the way
    That led them through Cavendish Square.'"

To our astonishment the Astronomer Royal at once took up the thread:--

 "'And as they passed by the great house of a lord,
    A beautiful chariot there came,
   To take some most elegant ladies abroad,
    Who straightway got into the same,'"

and went on to the end.  I do not know which of the two was more
surprised: Airy, to find an American woman who was interested in his
favorite ballad, or she to find that he could repeat it by heart.
The incident was the commencement of a family friendship which has
outlived both the heads of the Airy family.

We may look back on Airy as the most commanding figure in the
astronomy of our time.  He owes this position not only to his
early works in mathematical astronomy, but also to his ability as
an organizer.  Before his time the working force of an observatory
generally consisted of individual observers, each of whom worked to a
greater or less extent in his own way.  It is true that organization
was not unknown in such institutions.  Nominally, at least, the
assistants in a national observatory were supposed to follow the
instructions of a directing head.  This was especially the case
at Greenwich.  Still, great dependence was placed upon the judgment
and ability of the observer himself, who was generally expected to
be a man well trained in his specialty, and able to carry on good
work without much help.  From Airy's point of view, it was seen
that a large part of the work necessary to the attainment of the
traditional end of the Royal Observatory was of a kind that almost
any bright schoolboy could learn to do in a few weeks, and that in
most of the remaining part plodding industry, properly directed, was
more important than scientific training.  He could himself work out
all the mathematical formulæ and write all the instructions required
to keep a small army of observers and computers employed, and could
then train in his methods a few able lieutenants, who would see that
all the details were properly executed.  Under these lieutenants was a
grade comprising men of sufficient technical education to enable them
to learn how to point the telescope, record a transit, and perform the
other technical operations necessary in an astronomical observation.
A third grade was that of computers: ingenious youth, quick at
figures, ready to work for a compensation which an American laborer
would despise, yet well enough schooled to make simple calculations.
Under the new system they needed to understand only the four rules of
arithmetic; indeed, so far as possible Airy arranged his calculations
in such a way that subtraction and division were rarely required.
His boys had little more to do than add and multiply.  Thus, so far
as the doing of work was concerned, he introduced the same sort of
improvement that our times have witnessed in great manufacturing
establishments, where labor is so organized that unskilled men
bring about results that formerly demanded a high grade of technical
ability.  He introduced production on a large scale into astronomy.

At the time of my visit, it was much the fashion among astronomers
elsewhere to speak slightingly of the Greenwich system.  The
objections to it were, in substance, the same that have been made to
the minute subdivision of labor.  The intellect of the individual
was stunted for the benefit of the work.  The astronomer became a
mere operative.  Yet it must be admitted that the astronomical work
done at Greenwich during the sixty years since Airy introduced his
system has a value and an importance in its specialty that none
done elsewhere can exceed.  All future conclusions as to the laws
of motion of the heavenly bodies must depend largely upon it.

The organization of his little army necessarily involved a
corresponding change in the instruments they were to use.  Before his
time the trained astronomer worked with instruments of very delicate
construction, so that skill in handling them was one of the requisites
of an observer.  Airy made them in the likeness of heavy machinery,
which could suffer no injury from a blow of the head of a careless
observer.  Strong and simple, they rarely got out of order.  It is
said that an assistant who showed a visiting astronomer the transit
circle some times hit it a good slap to show how solid it was; but
this was not done on the present occasion.  The little army had its
weekly marching orders and made daily reports of progress to its
commander, who was thus enabled to control the minutest detail of
every movement.

In the course of the evening Airy gave me a lesson in method, which
was equally instructive and entertaining.  In order to determine the
longitude of Gibraltar, it was necessary that time signals should
be sent by telegraph from the Royal Observatory.  Our conversation
naturally led us into a discussion of the general subject of such
operations.  I told him of the difficulties we had experienced in
determining a telegraphic longitude,--that of the Harvard Observatory
from Washington, for example,--because it was only after a great deal
of talking and arranging on the evening of the observation that the
various telegraph stations between the two points could have their
connections successfully made at the same moment.  At the appointed
hour the Washington operator would be talking with the others,
to know if they were ready, and so a general discussion about the
arrangements might go on for half an hour before the connections
were all reported good.  If we had such trouble in a land line,
how should we get a connection from London to the Gibraltar cable
through lines in constant use?

"But," said Airy, "I never allow an operator who can speak with the
instruments to take part in determining a telegraphic longitude."

"Then how can you get the connections all made from one end of the
line to the other, at the same moment, if your operators cannot talk
to one another?"

"Nothing is simpler.  I fix in advance a moment, say eight
o'clock Greenwich mean time, at which signals are to commence.
Every intermediate office through which the signals are to pass is
instructed to have its wires connected in both directions exactly
at the given hour, and to leave them so connected for ten minutes,
without asking any further instructions.  At the end of the line
the instruments must be prepared at the appointed hour to receive
the signals.  All I have to do here is to place my clock in the
circuit and send on the signals for ten minutes, commencing at
eight o'clock.  They are recorded at the other end of the line
without further trouble."

"But have you never met with a failure to understand the
instructions?"

"No; they are too simple to be mistaken, once it is understood that
no one has anything to do but make his connections at the designated
moment, without asking whether any one else is ready."

Airy was noted not less for his ability as an organizer than for his
methodical habits.  The care with which he preserved every record led
Sir William Rowan Hamilton to say that when Airy wiped his pen on a
blotter, he fancied him as always taking a press copy of the mark.
His machinery seemed to work perfectly, whether it was constructed
of flesh or of brass.  He could prepare instructions for the most
complicated piece of work with such effective provision against
every accident and such completeness in every detail that the work
would go on for years without further serious attention from him.
The instruments which he designed half a century ago are mostly in
use to this day, with scarcely an alteration.

Yet there is some reason to fear that Airy carried method a little
too far to get the best results.  Of late years his system has been
greatly changed, even at Greenwich.  It was always questionable
whether so rigid a military routine could accomplish the best that
was possible in astronomy; and Airy himself, during his later years,
modified his plan by trying to secure trained scientific men as his
assistants, giving them liberty to combine independent research, on
their own account, with the work of the establishment.  His successor
has gone farther in the same direction, and is now gathering around
him a corps of young university men, from whose ability much may
be expected.  Observations with the spectroscope have been pursued,
and the observatory has taken a prominent part in the international
work of making a photographic map of the heavens.  Of special
importance are the regular discussions of photographs of the sun,
taken in order to determine the law of the variation of the spots.
The advantage of the regular system which has been followed for
more than fifty years is seen in the meteorological observations;
these disprove some theories of the relation between the sun and
the weather, in a way that no other set of meteorological records
has done.  While delicate determinations of the highest precision,
such as those made at Pulkova, are not yet undertaken to any great
extent, a regular even if slow improvement is going on in the general
character of the observations and researches, which must bear fruit
in due time.

One of the curious facts we learned at Greenwich was that astronomy
was still supposed to be astrology by many in England.  That a belief
in astrology should survive was perhaps not remarkable, though I
do not remember to have seen any evidence of it in this country.
But applications received at the Royal Observatory, from time to
time, showed a widespread belief among the masses that one of the
functions of the astronomer royal was the casting of horoscopes.


We went to Edinburgh.  Our first visit was to the observatory,
then under the direction of Professor C. Piazzi Smyth, who was also
an Egyptologist of repute, having made careful measurements of the
Pyramids, and brought out some new facts regarding their construction.
He was thus led to the conclusion that they bore marks of having been
built by a people of more advanced civilization than was generally
supposed,--so advanced, indeed, that we had not yet caught up to them
in scientific investigation.  These views were set forth with great
fullness in his work on "The Antiquity of Intellectual Man," as well
as in other volumes describing his researches.  He maintained that the
builders of the Pyramids knew the distance of the sun rather better
than we did, and that the height of the Great Pyramid had been so
arranged that if it was multiplied by a thousand millions we should
get this distance more exactly than we could measure it in these
degenerate days.  With him, to believe in the Pyramid was to believe
this, and a great deal more about the civilization which it proved.
So, when he asked me whether I believed in the Pyramid, I told him
that I did not think I would depend wholly upon the Pyramid for the
distance of the sun to be used in astronomy, but should want its
indications at least confirmed by modern researches.  The hint was
sufficient, and I was not further pressed for views on this subject.

He introduced us to Lady Hamilton, widow of the celebrated
philosopher, who still held court at Edinburgh.  The daughter of the
family was in repute as a metaphysician.  This was interesting,
because I had never before heard of a female metaphysician,
although there were several cases of female mathematicians
recorded in history.  First among them was Donna Maria Agnesi,
who wrote one of the best eighteenth-century books on the calculus,
and had a special dispensation from the Pope to teach mathematics
at Bologna.  We were therefore very glad to accept an invitation
from Lady Hamilton to spend an evening with a few of her friends.
Her rooms were fairly filled with books, the legacy of one of whom
it was said that "scarcely a thought has come down to us through
the ages which he has not mastered and made his own."

The few guests were mostly university people and philosophers.
The most interesting of them was Professor Blackie, the Grecian
scholar, who was the liveliest little man of sixty I ever saw;
amusing us by singing German songs, and dancing about the room like
a sprightly child among its playmates.  I talked with Miss Hamilton
about Mill, whose "Examination of Sir William Hamilton's Philosophy"
was still fresh in men's minds.  Of course she did not believe in this
book, and said that Mill could not understand her father's philosophy.
With all her intellect, she was a fine healthy-looking young lady,
and it was a sad surprise, a few years later, to hear of her death.
Madame Sophie Kovalevsky afterward appeared on the stage as the
first female mathematician of our time, but it may be feared that
the woman philosopher died with Miss Hamilton.


A large party of English astronomers were going to Algeria to observe
the eclipse.  The government had fitted up a naval transport for their
use, and as I was arranging for a passage on a ship of the Peninsular
and Oriental Line we received an invitation to become the guests of
the English party.  Among those on board were Professor Tyndall;
Mr. Huggins, the spectroscopist; Sir Erastus Ommaney, a retired
English admiral, and a fellow of the Royal Society; Father Perry,
S. J., a well-known astronomer; and Lieutenant Wharton, who afterward
became hydrographer to the Admiralty.

The sprightliest man on board was Professor Tyndall.  He made up
for the absence of mountains by climbing to every part of the ship
he could reach.  One day he climbed the shrouds to the maintop,
and stood surveying the scene as if looking out from the top of
the Matterhorn.  A sailor followed him, and drew a chalk-line around
his feet.  I assume the reader knows what this means; if he does not,
he can learn by straying into the sailors' quarters the first time he
is on board an ocean steamer.  But the professor absolutely refused
to take the hint.

We had a rather rough passage, from which Father Perry was the
greatest sufferer.  One day he heard a laugh from the only lady on
board, who was in the adjoining stateroom.  "Who can laugh at such
a time as this!" he exclaimed.  He made a vow that he would never
go on the ocean again, even if the sun and moon fought for a month.
But the vows of a seasick passenger are forgotten sooner than any
others I know of; and it was only four years later that Father Perry
made a voyage to Kerguelen Island, in the stormiest ocean on the
globe, to observe a transit of Venus.

Off the coast of Spain, the leading chains of the rudder got loose,
during a gale in the middle of the night, and the steering apparatus
had to be disconnected in order to tighten them.  The ship veered
round into the trough of the sea, and rolled so heavily that a table,
twenty or thirty feet long, in the saloon, broke from its fastenings,
and began to dance around the cabin with such a racket that some of
the passengers feared for the safety of the ship.

Just how much of a storm there was I cannot say, believing that it
is never worth while for a passenger to leave his berth, if there
is any danger of a ship foundering in a gale.  But in Professor
Tyndall's opinion we had a narrow escape.  On arriving at Gibraltar,
he wrote a glowing account of the storm to the London Times, in
which he described the feelings of a philosopher while standing on
the stern of a rolling ship in an ocean storm, without quite knowing
whether she was going to sink or swim.  The letter was anonymous,
which gave Admiral Ommaney an excellent opportunity to write as
caustic a reply as he chose, under the signature of "A Naval Officer."
He said that sailor was fortunate who could arrange with the clerk
of the weather never to have a worse storm in crossing the Bay of
Biscay than the one we had experienced.

We touched at Cadiz, and anchored for a few hours, but did not go
ashore.  The Brooklyn, an American man-of-war, was in the harbor,
but there was no opportunity to communicate with her, though I knew
a friend of mine was on board.

Gibraltar is the greatest babel in the world, or, at least, the
greatest I know.  I wrote home: "The principal languages spoken at
this hotel are English, Spanish, Moorish, French, Italian, German,
and Danish.  I do not know what languages they speak at the other
hotels."  Moorish and Spanish are the local tongues, and of course
English is the official one; but the traders and commercial travelers
speak nearly every language one ever heard.

I hired a Moor--who bore some title which indicated that he was a
descendant of the Caliphs, and by which he had to be addressed--to do
chores and act as general assistant.  One of the first things I did,
the morning after my arrival, was to choose a convenient point on
one of the stone parapets for "taking the sun," in order to test the
running of my chronometer.  I had some suspicion as to the result,
but was willing to be amused.  A sentinel speedily informed me that
no sights were allowed to be taken on the fortification.  I told him
I was taking sights on the sun, not on the fortification.  But he was
inexorable; the rule was that no sights of any sort could be taken
without a permit.  I soon learned from Mr. Sprague, the American
consul, who the proper officer was to issue the permit, which I
was assured would be granted without the slightest difficulty.
The consul presented me to the military governor of the place,
General Sir Fenwick Williams of Kars.  I did not know till long
afterward that he was born very near where I was.  He was a man whom
it was very interesting to meet.  His heroic defense of the town whose
name was added to his own as a part of his title was still fresh in
men's minds.  It had won him the order of the Bath in England, the
Grand Cross of the Legion of Honor and a sword from Napoleon III., and
the usual number of lesser distinctions.  The military governor, the
sole authority and viceroy of the Queen in the fortress, is treated
with the deference due to an exalted personage; but this deference
so strengthens the dignity of the position that the holder may be
frank and hearty at his own pleasure, without danger of impairing it.
Certainly, we found Sir Fenwick a most genial and charming gentleman.
The Alabama claims were then in their acute stage, and he expressed
the earnest hope that the two nations would not proceed to cutting
each other's throats over them.

There was no need of troubling the governor with such a detail as
that of a permit to take sights; but the consul ventured to relate
my experience of the morning.  He took the information in a way
which showed that England, in making him a general, had lost a
good diplomatist.  Instead of treating the matter seriously, which
would have implied that we did not fully understand the situation, he
professed to be greatly amused, and said it reminded him of the case
of an old lady in "Punch" who had to pass a surveyor in the street,
behind a theodolite.  "Please, sir, don't shoot till I get past,"
she begged.

Before leaving England, I had made very elaborate arrangements,
both with the Astronomer Royal and with the telegraph companies,
to determine the longitude of Gibraltar by telegraphic signals.
The most difficult part of the operation was the transfer of the
signals from the end of the land line into the cable, which had to
be done by hand, because the cable companies were not willing to
trust to an automatic action of any sort between the land line and
the cable.  It was therefore necessary to show the operator at the
point of junction how signals were to be transmitted.  This required
a journey to Port Curno, at the very end of the Land's End, several
miles beyond the terminus of the railway.  It was the most old-time
place I ever saw; one might have imagined himself thrown back into the
days of the Lancasters.  The thatched inn had a hard stone floor, with
a layer of loose sand scattered over it as a carpet in the bedroom.
My linguistic qualities were put to a severe test in talking with
the landlady.  But the cable operators were pleasing and intelligent
young gentlemen, and I had no difficulty in making them understand
how the work was to be done.

The manager of the cable was Sir James Anderson, who had formerly
commanded a Cunard steamship from Boston, and was well known to
the Harvard professors, with whom he was a favorite.  I had met
him, or at least seen him, at a meeting of the American Academy ten
years before, where he was introduced by one of his Harvard friends.
After commanding the ship that laid the first Atlantic cable, he was
made manager of the cable line from England to Gibraltar.  He gave me
a letter to the head operator at Gibraltar, the celebrated de Sauty.

I say "the celebrated," but may it not be that this appellation can
only suggest the vanity of all human greatness?  It just occurs to me
that many of the present generation may not even have heard of the--

    Whispering Boanerges, son of silent thunder,
        Holding talk with nations,

immortalized by Holmes in one of his humorously scientific poems.
During the two short weeks that the first Atlantic cable transmitted
its signals, his fame spread over the land, for the moment obscuring
by its brilliancy that of Thomson, Field, and all others who had
taken part in designing and laying the cable.  On the breaking down
of the cable he lapsed into his former obscurity.  I asked him if he
had ever seen Holmes's production.  He replied that he had received a
copy of "The Atlantic Monthly" containing it from the poet himself,
accompanied by a note saying that he might find in it something
of interest.  He had been overwhelmed with invitations to continue
his journey from Newfoundland to the United States and lecture on
the cable, but was sensible enough to decline them.

The rest of the story of the telegraphic longitude is short.
The first news which de Sauty had to give me was that the cable was
broken,--just where, he did not know, and would not be able soon to
discover.  After the break was located, an unknown period would be
required to raise the cable, find the place, and repair the breach.
The weather, on the day of the eclipse, was more than half cloudy,
so that I did not succeed in making observations of such value as
would justify my waiting indefinitely for the repair of the cable,
and the project of determining the longitude had to be abandoned.




XI

MEN AND THINGS IN EUROPE


We went from Gibraltar to Berlin in January by way of Italy.
The Mediterranean is a charming sea in summer, but in winter is
a good deal like the Atlantic.  The cause of the blueness of its
water is not completely settled; but its sharing this color with
Lake Geneva, which is tinged with detritus from the shore, might
lead one to ascribe it to substances held in solution.  The color is
noticeable even in the harbor of Malta, to which we had a pleasant
though not very smooth passage of five days.

Here was our first experience of an Italian town of a generation
ago.  I had no sooner started to take a walk than a so-called
guide, who spoke what he thought was English, got on my track,
and insisted on showing me everything.  If I started toward a shop,
he ran in before me, invited me in, asked what I would like to buy,
and told the shopman to show the gentleman something.  I could not
get rid of him till I returned to the hotel, and then he had the
audacity to want a fee for his services.  I do not think he got it.
Everything of interest was easily seen, and we only stopped to take
the first Italian steamer to Messina.  We touched at Syracuse and
Catania, but did not land.

Ætna, from the sea, is one of the grandest sights I ever saw.
Its snow-covered cone seems to rise on all sides out of the sea
or the plain, and to penetrate the blue sky.  In this it gives an
impression like that of the Weisshorn seen from Randa, but gains by
its isolation.

At Messina, of course, our steamer was visited by a commissionnaire,
who asked me in good English whether I wanted a hotel.  I told him
that I had already decided upon a hotel, and therefore did not need
his services.  But it turned out that he belonged to the very hotel
I was going to, and was withal an American, a native-born Yankee, in
fact, and so obviously honest that I placed myself unreservedly in
his hands,--something which I never did with one of his profession
before or since.  He said the first thing was to get our baggage
through the custom-house, which he could do without any trouble,
at the cost of a franc.  He was as good as his word.  The Italian
custom-house was marked by primitive rigor, and baggage was commonly
subjected to a very thorough search.  But my man was evidently well
known and fully trusted.  I was asked to raise the lid of one trunk,
which I did; the official looked at it, with his hands in his pockets,
gave a nod, and the affair was over.  My Yankee friend collected one
franc for that part of the business.  He told us all about the place,
changed our money so as to take advantage of the premium on gold,
and altogether looked out for our interests in a way to do honor to
his tribe.  I thought there might be some curious story of the way
in which a New Englander of such qualities could have dropped into
such a place, but it will have to be left to imagination.

We reached the Bay of Naples in the morning twilight, after making
an unsuccessful attempt to locate Scylla and Charybdis.  If they
ever existed, they must have disappeared.  Vesuvius was now and
then lighting up the clouds with its intermittent flame.  But we
had passed a most uncomfortable night, and the morning was wet and
chilly.  A view requires something more than the objective to make
it appreciated, and the effect of a rough voyage and bad weather
was such as to deprive of all its beauty what is considered one of
the finest views in the world.  Moreover, the experience made me so
ill-natured that I was determined that the custom-house officer at the
landing should have no fee from me.  The only article that could have
been subject to duty was on top of everything in the trunk, except
a single covering of some loose garment, so that only a touch was
necessary to find it.  When it came to the examination, the officer
threw the top till contemptuously aside, and devoted himself to a
thorough search of the bottom.  The only unusual object he stumbled
upon was a spyglass inclosed in a shield of morocco.  Perhaps a
gesture and a remark on my part aroused his suspicions.  He opened
the glass, tried to take it to pieces, inspected it inside and out,
and was so disgusted with his failure to find anything contraband
in it that he returned everything to the trunk, and let us off.

It is commonly and quite justly supposed that the more familiar the
traveler is with the language of the place he visits, the better he
will get along.  It is a common experience to find that even when
you can pronounce the language, you cannot understand what is said.
But there are exceptions to all rules, and circumstances now and then
occur in which one thus afflicted has an advantage over the native.
You can talk to him, while he cannot talk to you.  There was an
amusing case of this kind at Munich.  The only train that would take
us to Berlin before nightfall of the same day left at eight o'clock
in the morning, by a certain route.  There was at Munich what we
call a union station.  I stopped at the first ticket-office where I
saw the word "Berlin" on the glass, asked for a ticket good in the
train that was going to leave at eight o'clock the next morning for
Berlin, and took what the seller gave me.  He was a stupid-looking
fellow, so when I got to my hotel I showed the ticket to a friend.
"That is not the ticket that you want at all," said he; "it will
take you by a circuitous route in a train that does not leave until
after nine, and you will not reach Berlin until long after dark."
I went directly back to the station and showed my ticket to the agent.

"I--asked--you--for--a--ticket--good--in--the--train--which--
leaves--at--eight--o'--clock.  This--ticket--is--not--good--
in--that--train.  Sie--haben--mich--betrügen.  I--want--you--
to--take--the--ticket--back--and--return--me--the--money.
What--you--say--can--I--not--understand."

He expostulated, gesticulated, and fumed, but I kept up the
bombardment until he had to surrender.  He motioned to me to step
round into the office, where he took the ticket and returned the
money.  I mention the matter because taking back a ticket is said
to be quite unusual on a German railway.


At Berlin, the leading astronomers then, as now, were Förster,
director of the observatory, and Auwers, permanent secretary of the
Academy of Sciences.  I was especially interested in the latter,
as we had started in life nearly at the same time, and had done
much work on similar lines.  It was several days before I made his
acquaintance, as I did not know that the rule on the Continent
is that the visitor must make the first call, or at least make
it known by direct communication that he would be pleased to see
the resident; otherwise it is presumed that he does not wish to
see callers.  This is certainly the more logical system, but it is
not so agreeable to the visiting stranger as ours is.  The art of
making the latter feel at home is not brought to such perfection on
the Continent as in England; perhaps the French understand it less
than any other people.  But none can be pleasanter than the Germans,
when you once make their acquaintance; and we shall always remember
with pleasure the winter we passed in Berlin.

To-day, Auwers stands at the head of German astronomy.  In him is
seen the highest type of the scientific investigator of our time,
one perhaps better developed in Germany than in any other country.
The work of men of this type is marked by minute and careful research,
untiring industry in the accumulation of facts, caution in propounding
new theories or explanations, and, above all, the absence of effort
to gain recognition by being the first to make a discovery.  When men
are ambitious to figure as Newtons of some great principle, there is
a constant temptation to publish unverified speculations which are
likely rather to impede than to promote the advance of knowledge.
The result of Auwers's conscientiousness is that, notwithstanding
his eminence in his science, there are few astronomers of note whose
works are less fitted for popular exposition than his.  His specialty
has been the treatment of all questions concerning the positions and
motions of the stars.  This work has required accurate observations
of position, with elaborate and careful investigations of a kind that
offer no feature to attract public attention, and only in exceptional
cases lead to conclusions that would interest the general reader.
He considers no work as ready for publication until it is completed
in every detail.


The old astronomical observations of which I was in quest might
well have been made by other astronomers than those of Paris, so
while awaiting the end of the war I tried to make a thorough search
of the writings of the mediæval astronomers in the Royal Library.
If one knew exactly what books he wanted, and had plenty of time
at his disposal, he would find no difficulty in consulting them
in any of the great Continental libraries.  But at the time of my
visit, notwithstanding the cordiality with which all the officials,
from Professor Lepsius down, were disposed to second my efforts,
the process of getting any required book was very elaborate.
Although one could obtain a book on the same day he ordered it,
if he went in good time, it was advisable to leave the order the
day before, if possible.  When, as in the present case, one book
only suggests another, this a third, and so on, in an endless chain,
the carrying on of an extended research is very tedious.

One feature of the library strongly impressed me with the
comparatively backward state of mathematical science in our own
country.  As is usual in the great European libraries, those books
which are most consulted are placed in the general reading-room, where
any one can have access to them, at any moment.  It was surprising to
see amongst these books a set of Crelle's "Journal of Mathematics,"
and to find it well worn by constant use.  At that time, so far
as I could learn, there were not more than two or three sets of
the Journal in the United States; and these were almost unused.
Even the Library of Congress did not contain a set.  There has
been a great change since that time,--a change in which the Johns
Hopkins University took the lead, by inviting Sylvester to this
country, and starting a mathematical school of the highest grade.
Other universities followed its example to such an extent that,
to-day, an American student need not leave his own country to hear
a master in any branch of mathematics.


I believe it was Dr. B. A. Gould who called the Pulkova Observatory
the astronomical capital of the world.  This institution was founded
in 1839 by the Emperor Nicholas, on the initiative of his greatest
astronomer.  It is situated some twelve miles south of St. Petersburg,
not far from the railway between that city and Berlin, and gets its
name from a peasant village in the neighborhood.  From its foundation
it has taken the lead in exact measurements relating to the motion
of the earth and the positions of the principal stars.  An important
part of its equipment is an astronomical library, which is perhaps the
most complete in existence.  This, added to all its other attractions,
induced me to pay a visit to Pulkova.  Otto Struve, the director,
had been kind enough to send me a message, expressing the hope that
I would pay him a visit, and giving directions about telegraphing
in advance, so as to insure the delivery of the dispatch.  The time
from Berlin to St. Petersburg is about forty-eight hours, the only
through train leaving and arriving in the evening.  On the morning
of the day that the train was due I sent the dispatch.  Early in
the afternoon, as the train was stopping at a way station, I saw
an official running hastily from one car to another, looking into
each with some concern.  When he came to my door, he asked if I had
sent a telegram to Estafetta.  I told him I had.  He then informed
me that Estafetta had not received it.  But the train was already
beginning to move, so there was no further chance to get information.
The comical part of the matter was that "Estafetta" merely means a
post or postman, and that the directions, as Struve had given them,
were to have the dispatch sent by postman from the station to Pulkova.

It was late in the evening when the train reached Zarsko-Selo,
the railway station for Pulkova, which is about five miles away.
The station-master told me that no carriage from Pulkova was waiting
for me, which tended to confirm the fear that the dispatch had not
been received.  After making known my plight, I took a seat in the
station and awaited the course of events, in some doubt what to do.
Only a few minutes had elapsed when a good-looking peasant, well
wrapped in a fur overcoat, with a whip in his hand, looked in at
the door, and pronounced very distinctly the words, "Observatorio
Pulkova."  Ah! this is Struve's driver at last, thought I, and I
followed the man to the door.  But when I looked at the conveyance,
doubt once more supervened.  It was scarcely more than a sledge,
and was drawn by a single horse, evidently more familiar with hard
work than good feeding.  This did not seem exactly the vehicle that
the great Russian observatory would send out to meet a visitor;
yet it was a far country, and I was not acquainted with its customs.

The way in which my doubt was dispelled shows that there is one
subject besides love on which difference of language is no bar to
the communication of ideas.  This is the desire of the uncivilized
man for a little coin of the realm.  In South Africa, Zulu chiefs,
who do not know one other word of English, can say "shilling" with
unmistakable distinctness.  My Russian driver did not know even this
little English word, but he knew enough of the universal language.
When we had made a good start on the snow-covered prairie, he stopped
his horse for a moment, looked round at me inquiringly, raised his
hand, and stretched out two fingers so that I could see them against
the starlit sky.

I nodded assent.

Then he drew his overcoat tightly around him with a gesture of
shivering from the cold, beat his hands upon his breast as if to
warm it, and again looked inquiringly at me.

I nodded again.

The bargain was complete.  He was to have two rubles for the drive,
and a little something to warm up his shivering breast.  So he could
not be Struve's man.

There is no welcome warmer than a Russian one, and none in any
country warmer than that which the visiting astronomer receives at an
observatory.  Great is the contrast between the winter sky of a clear
moonless night and the interior of a dining-room, forty feet square,
with a big blazing fire at one end and a table loaded with eatables
in the middle.  The fact that the visitor had never before met one
of his hosts detracted nothing from the warmth of his reception.

The organizer of the observatory, and its first director, was Wilhelm
Struve, father of the one who received me, and equally great as man
and astronomer.  Like many other good Russians, he was the father of a
large family.  One of his sons was for ten years the Russian minister
at Washington, and as popular a diplomatist as ever lived among us.
The instruments which Struve designed sixty years ago still do as
fine work as any in the world; but one may suspect this to be due more
to the astronomers who handle them than to the instruments themselves.

The air is remarkably clear; the entrance to St. Petersburg, ten or
twelve miles north, is distinctly visible, and Struve told me that
during the Crimean war he could see, through the great telescope,
the men on the decks of the British ships besieging Kronstadt,
thirty miles away.

One drawback from which the astronomers suffer is the isolation of
the place.  The village at the foot of the little hill is inhabited
only by peasants, and the astronomers and employees have nearly all
to be housed in the observatory buildings.  There is no society but
their own nearer than the capital.  At the time of my visit the
scientific staff was almost entirely German or Swedish, by birth
or language.  In the state, two opposing parties are the Russian,
which desires the ascendency of the native Muscovites, and the German,
which appreciates the fact that the best and most valuable of the
Tsar's subjects are of German or other foreign descent.  During the
past twenty years the Russian party has gradually got the upper hand;
and the result of this ascendency at Pulkova will be looked for with
much solicitude by astronomers everywhere.

Once a year the lonely life of the astronomers is enlivened by a
grand feast--that of the Russian New Year.  One object of the great
dining-room which I have mentioned, the largest room, I believe, in
the whole establishment, was to make this feast possible.  My visit
took place early in March, so that I did not see the celebration;
but from what I have heard, the little colony does what it can to
make up for a year of ennui.  Every twenty-five years it celebrates
a jubilee; the second came off in 1889.

There is much to interest the visitor in a Russian peasant
village, and that of Pulkova has features some of which I have
never seen described.  Above the door of each log hut is the name
of the occupant, and below the name is a rude picture of a bucket,
hook, or some other piece of apparatus used in extinguishing fire.
Inside, the furniture is certainly meagre enough, yet one could
not see why the occupants should be otherwise than comfortable.
I know of no good reason why ignorance should imply unhappiness;
altogether, there is some good room for believing that the less
civilized races can enjoy themselves, in their own way, about as
well as we can.  What impressed me as the one serious hardship of
the peasantry was their hours of labor.  Just how many hours of
the twenty-four these beings find for sleep was not clear to the
visitor; they seemed to be at work all day, and at midnight many of
them had to start on their way to St. Petersburg with a cartload
for the market.  A church ornamented with tinsel is a feature of
every Russian village; so also are the priests.  The only two I saw
were sitting on a fence, wearing garments that did not give evidence
of having known water since they were made.  One great drawback to
the growth of manufactures in Russia is the number of feast days,
on which the native operators must one and all abandon their work,
regardless of consequences.

The astronomical observations made at Pulkova are not published
annually, as are those made at most of the other national
observatories; but a volume relating to one subject is issued whenever
the work is done.  When I was there, the volumes containing the
earlier meridian observations were in press.  Struve and his chief
assistant, Dr. Wagner, used to pore nightly over the proof sheets,
bestowing on every word and detail a minute attention which less
patient astronomers would have found extremely irksome.

Dr. Wagner was a son-in-law of Hansen, the astronomer of the little
ducal observatory at Gotha, as was also our Bayard Taylor.  My first
meeting with Hansen, which occurred after my return to Berlin, was
accompanied with some trepidation.  Modest as was the public position
that he held, he may now fairly be considered the greatest master of
celestial mechanics since Laplace.  In what order Leverrier, Delaunay,
Adams, and Hill should follow him, it is not necessary to decide.
To many readers it will seem singular to place any name ahead of
that of the master who pointed out the position of Neptune before
a human eye had ever recognized it.  But this achievement, great
as it was, was more remarkable for its boldness and brilliancy than
for its inherent difficulty.  If the work had to be done over again
to-day, there are a number of young men who would be as successful
as Leverrier; but there are none who would attempt to reinvent
the methods of Hansen, or even to improve radically upon them.
Their main feature is the devising of new and refined methods of
computing the variations in the motions of a planet produced by the
attraction of all the other planets.  As Laplace left this subject,
the general character of these variations could be determined without
difficulty, but the computations could not be made with mathematical
exactness.  Hansen's methods led to results so precise that, if they
were fully carried out, it is doubtful whether any deviation between
the predicted and the observed motions of a planet could be detected
by the most refined observation.

At the time of my visit Mrs. Wagner was suffering from a severe
illness, of which the crisis passed while I was at Pulkova, and
left her, as was supposed, on the road to recovery.  I was, of
course, very desirous of meeting so famous a man as Hansen.  He was
expected to preside at a session of the German commission on the
transit of Venus, which was to be held in Berlin about the time of
my return thither from Pulkova.  The opportunity was therefore open
of bringing a message of good news from his daughter.  Apart from
this, the prospect of the meeting might have been embarrassing.
The fact is that I was at odds with him on a scientific question,
and he was a man who did not take a charitable view of those who
differed from him in opinion.

He was the author of a theory, current thirty or forty years ago,
that the farther side of the moon is composed of denser materials
than the side turned toward us.  As a result of this, the centre
of gravity of the moon was supposed to be farther from us than the
actual centre of her globe.  It followed that, although neither
atmosphere nor water existed on our side of the moon, the other
side might have both.  Here was a very tempting field into which
astronomical speculators stepped, to clothe the invisible hemisphere
of the moon with a beautiful terrestrial landscape, and people it as
densely as they pleased with beings like ourselves.  If these beings
should ever attempt to explore the other half of their own globe,
they would find themselves ascending to a height completely above
the limits of their atmosphere.  Hansen himself never countenanced
such speculations as these, but confined his claims to the simple
facts he supposed proven.

In 1868 I had published a little paper showing what I thought a
fatal defect, a vicious circle in fact, in Hansen's reasoning on
this subject.  Not long before my visit, Delaunay had made this paper
the basis of a communication to the French Academy of Sciences, in
which he not only indorsed my views, but sought to show the extreme
improbability of Hansen's theory on other grounds.

When I first reached Germany, on my way from Italy, I noticed
copies of a blue pamphlet lying on the tables of the astronomers.
Apparently, the paper had been plentifully distributed; but it was
not until I reached Berlin that I found it was Hansen's defense
against my strictures,--a defense in which mathematics were not
unmixed with seething sarcasm at the expense of both Delaunay
and myself.  The case brought to mind a warm discussion between
Hansen and Encke, in the pages of a scientific journal, some fifteen
years before.  At the time it had seemed intensely comical to see two
enraged combatants--for so I amused myself by fancying them--hurling
algebraic formulæ, of frightful complexity, at each other's heads.
I did not then dream that I should live to be an object of the same
sort of attack, and that from Hansen himself.

To be revised, pulled to pieces, or superseded, as science advances,
is the common fate of most astronomical work, even the best.
It does not follow that it has been done in vain; if good, it
forms a foundation on which others will build.  But not every great
investigator can look on with philosophic calm when he sees his work
thus treated, and Hansen was among the last who could.  Under these
circumstances, it was a serious question what sort of reception Hansen
would accord to a reviser of his conclusions who should venture to
approach him.  I determined to assume an attitude that would show
no consciousness of offense, and was quite successful.  Our meeting
was not attended by any explosion; I gave him the pleasant message
with which I was charged from his daughter, and, a few days later,
sat by his side at a dinner of the German commission on the coming
transit of Venus.

As Hansen was Germany's greatest master in mathematical astronomy,
so was the venerable Argelander in the observational side of the
science.  He was of the same age as the newly crowned Emperor,
and the two were playmates at the time Germany was being overrun
by the armies of Napoleon.  He was held in love and respect by the
entire generation of young astronomers, both Germans and foreigners,
many of whom were proud to have had him as their preceptor.  Among
these was Dr. B. A. Gould, who frequently related a story of the
astronomer's wit.  When with him as a student, Gould was beardless,
but had a good head of hair.  Returning some years later, he had
become bald, but had made up for it by having a full, long beard.
He entered Argelander's study unannounced.  At first the astronomer
did not recognize him.

"Do you not know me, Herr Professor?"

The astronomer looked more closely.  "Mine Gott!  It is Gould mit
his hair struck through!"

Argelander was more than any one else the founder of that branch of
his science which treats of variable stars.  His methods have been
followed by his successors to the present time.  It was his policy
to make the best use he could of the instruments at his disposal,
rather than to invent new ones that might prove of doubtful utility.
The results of his work seem to justify this policy.

We passed the last month of the winter in Berlin waiting for the
war to close, so that we could visit Paris.  Poor France had at
length to succumb, and in the latter part of March, we took almost
the first train that passed the lines.

Delaunay was then director of the Paris Observatory, having succeeded
Leverrier when the emperor petulantly removed the latter from his
position.  I had for some time kept up an occasional correspondence
with Delaunay, and while in England, the autumn before, had forwarded
a message to him, through the Prussian lines, by the good offices
of the London legation and Mr. Washburn.  He was therefore quite
prepared for our arrival.  The evacuation of a country by a hostile
army is rather a slow process, so that the German troops were met
everywhere on the road, even in France.  They had left Paris just
before we arrived; but the French national army was not there,
the Communists having taken possession of the city as fast as the
Germans withdrew.  As we passed out of the station, the first object
to strike our eyes was a flaming poster addressed to "Citoyens,"
and containing one of the manifestoes which the Communist government
was continually issuing.

Of course we made an early call on Mr. Washburn.  His career in
Paris was one of the triumphs of diplomacy; he had cared for the
interests of German subjects in Paris in such a way as to earn the
warm recognition both of the emperor and of Bismarck, and at the
same time had kept on such good terms with the French as to be not
less esteemed by them.  He was surprised that we had chosen such a
time to visit Paris; but I told him the situation, the necessity
of my early return home, and my desire to make a careful search
in the records of the Paris Observatory for observations made two
centuries ago.  He advised us to take up our quarters as near to
the observatory as convenient, in order that we might not have to
pass through the portions of the city which were likely to be the
scenes of disturbance.

We were received at the observatory with a warmth of welcome that
might be expected to accompany the greeting of the first foreign
visitor, after a siege of six months.  Yet a tinge of sadness in
the meeting was unavoidable.  Delaunay immediately began lamenting
the condition of his poor ruined country, despoiled of two of its
provinces by a foreign foe, condemned to pay an enormous subsidy
in addition, and now the scene of an internal conflict the end of
which no one could foresee.

While I was mousing among the old records of the Paris Observatory,
the city was under the reign of the Commune and besieged by the
national forces.  The studies had to be made within hearing of
the besieging guns; and I could sometimes go to a window and see
flashes of artillery from one of the fortifications to the south.
Nearly every day I took a walk through the town, occasionally as
far as the Arc de Triomphe.  The story of the Commune has been so
often written that I cannot hope to add anything to it, so far as the
main course of events is concerned.  Looking back on a sojourn at so
interesting a period, one cannot but feel that a golden opportunity
to make observations of historic value was lost.  The fact is,
however, that I was prevented from making such observations not only
by my complete absorption in my work, but by the consideration that,
being in what might be described as a semi-official capacity, I did
not want to get into any difficulty that would have compromised
the position of an official visitor.  I should not deem what we
saw worthy of special mention, were it not that it materially
modifies the impressions commonly given by writers on the history
of the Commune.  What an historian says may be quite true, so far
as it goes, and yet may be so far from the whole truth as to give
the reader an incorrect impression of the actual course of events.
The violence and disease which prevail in the most civilized country
in the world may be described in such terms as to give the impression
of a barbarous community.  The murder of the Archbishop of Paris and
of the hostages show how desperate were the men who had seized power,
yet the acts of these men constitute but a small part of the history
of Paris during that critical period.

What one writes at the time is free from the suspicion that may
attach to statements not recorded till many years after the events
to which they relate.  The following extract from a letter which I
wrote to a friend, the day after my arrival, may therefore be taken
to show how things actually looked to a spectator:--

 Dear Charlie,--Here we are, on this slumbering volcano.
 Perhaps you will hear of the burst-up long before you get
 this.  We have seen historic objects which fall not to the
 lot of every generation, the barricades of the Paris streets.
 As we were walking out this morning, the pavement along one
 side of the street was torn up for some distance, and used
 to build a temporary fort.  Said fort would be quite strong
 against musketry or the bayonet; but with heavy shot against
 it, I should think it would be far worse than nothing,
 for the flying stones would kill more than the balls.

 The streets are placarded at every turn with all sorts of
 inflammatory appeals, and general orders of the Comité
 Central or of the Commune.  One of the first things I
 saw last night was a large placard beginning "Citoyens!"
 Among the orders is one forbidding any one from placarding
 any orders of the Versailles government under the severest
 penalties; and another threatening with instant dismissal
 any official who shall recognize any order issuing from
 the said government.

 I must do all hands the justice to say that they are all
 very well behaved.  There is nothing like a mob anywhere, so
 far as I can find.  I consulted my map this morning, right
 alongside the barricade and in full view of the builders,
 without being molested, and wife and I walked through the
 insurrectionary districts without being troubled or seeing
 the slightest symptoms of disturbance.  The stores are all
 open, and every one seems to be buying and selling as usual.
 In all the cafés I have seen, the habitués seem to be
 drinking their wine just as coolly as if they had nothing
 unusual on their minds.

From this date to that of our departure I saw nothing suggestive
of violence within the limited range of my daily walks, which were
mostly within the region including the Arc de Triomphe, the Hôtel
de Ville, and the observatory; the latter being about half a mile
south of the Luxembourg.  The nearest approach to a mob that I
ever noticed was a drill of young recruits of the National Guard,
or a crowd in the court of the Louvre being harangued by an orator.
With due allowance for the excitability of the French nature,
the crowd was comparatively as peaceable as that which we may see
surrounding a gospel wagon in one of our own cities.  A drill-ground
for the recruits happened to be selected opposite our first lodgings,
beside the gates of the Luxembourg.  This was so disagreeable that we
were glad to accept an invitation from Delaunay to be his guests at
the observatory, during the remainder of our stay.  We had not been
there long before the spacious yard of the observatory was also used
as a drill-ground; and yet later, two or three men were given _billets
de logement_ upon the observatory; but I should not have known of the
latter occurrence, had not Delaunay told me.  I believe he bought
the men off, much as one pays an organ-grinder to move on.  In one
of our walks we entered the barricade around the Hôtel de Ville, and
were beginning to make a close examination of a mitrailleuse, when a
soldier (beg his pardon, _un citoyen membre de la Garde Nationale_)
warned us away from the weapon.  The densest crowd of Communists was
along the Rue de Rivoli and in the region of the Colonne Vendôme,
where some of the principal barricades were being erected.  But even
here, not only were the stores open as usual, but the military were
doing their work in the midst of piles of trinkets exposed for sale
on the pavement by the shopwomen.  The order to destroy the Column
was issued before we left, but not executed until later.  I have no
reason to suppose that the shopwomen were any more concerned while
the Column was being undermined than they were before.  To complete
the picture, not a policeman did we see in Paris; in fact, I was
told that one of the first acts of the Commune had been to drive
the police away, so that not one dared to show himself.

An interesting feature of the sad spectacle was the stream of
proclamations poured forth by the Communist authorities.  They
comprised not only decrees, but sensational stories of victories over
the Versailles troops, denunciations of the Versailles government,
and even elaborate legal arguments, including a not intemperate
discussion of the ethical question whether citizens who were not
adherents of the Commune should be entitled to the right of suffrage.
The conclusion was that they should not.  The lack of humor on the
part of the authorities was shown by their commencing one of a rapid
succession of battle stories with the words, "Citoyens!  Vous avez
soif de la vérité!"  The most amusing decree I noticed ran thus:--

"Article I. All conscription is abolished.

"Article II. No troops shall hereafter be allowed in Paris, except
the National Guard.

"Article III. Every citizen is a member of the National Guard."

We were in daily expectation and hope of the capture of the city,
little imagining by what scenes it would be accompanied.  It did not
seem to my unmilitary eye that two or three batteries of artillery
could have any trouble in demolishing all the defenses, since a
wall of paving-stones, four or five feet high, could hardly resist
solid shot, or prove anything but a source of destruction to those
behind it if attacked by artillery.  But the capture was not so easy
a matter as I had supposed.

We took leave of our friend and host on May 5, three weeks before
the final catastrophe, of which he wrote me a graphic description.
As the barricades were stormed by MacMahon, the Communist line of
retreat was through the region of the observatory.  The walls of
the building and of the yard were so massive that the place was
occupied as a fort by the retreating forces, so that the situation
of the few non-combatants who remained was extremely critical.
They were exposed to the fire of their friends, the national troops,
from without, while enraged men were threatening their lives within.
So hot was the fusillade that, going into the great dome after the
battle, the astronomer could imagine all the constellations of the
sky depicted by the bullet-holes.  When retreat became inevitable,
the Communists tried to set the building on fire, but did not succeed.
Then, in their desperation, arrangements were made for blowing it up;
but the most violent man among them was killed by a providential
bullet, as he was on the point of doing his work.  The remainder
fled, the place was speedily occupied by the national troops, and
the observatory with its precious contents was saved.

The Academy of Sciences had met regularly through the entire Prussian
siege.  The legal quorum being three, this did not imply a large
attendance.  The reason humorously assigned for this number was that,
on opening a session, the presiding officer must say, _Messieurs,
la séance est ouverte_, and he cannot say _Messieurs_ unless there
are at least two to address.  At the time of my visit a score of
members were in the city.  Among them were Elie de Beaumont, the
geologist; Milne-Edwards, the zoölogist; and Chevreul, the chemist.
I was surprised to learn that the latter was in his eighty-fifth
year; he seemed a man of seventy or less, mentally and physically.
Yet we little thought that he would be the longest-lived man of equal
eminence that our age has known.  When he died, in 1889, he was nearly
one hundred and three years old.  Born in 1786, he had lived through
the whole French Revolution, and was seven years old at the time of
the Terror.  His scientific activity, from beginning to end, extended
over some eighty years.  When I saw him, he was still very indignant
at a bombardment of the Jardin des Plantes by the German besiegers.
He had made a formal statement of this outrage to the Academy of
Sciences, in order that posterity might know what kind of men were
besieging Paris.  I suggested that the shells might have fallen in
the place by accident; but he maintained that it was not the case,
and that the bombardment was intentional.

The most execrated man in the scientific circle at this time was
Leverrier.  He had left Paris before the Prussian siege began, and had
not returned.  Delaunay assured me that this was a wise precaution
on his part; for had he ventured into the city he would have been
mobbed, or the Communists would have killed him as soon as caught.
Just why the mob should have been so incensed against one whose
life was spent in the serenest fields of astronomical science was
not fully explained.  The fact that he had been a senator, and was
politically obnoxious, was looked on as an all-sufficient indictment.
Even members of the Academy could not suppress their detestation
of him.  Their language seemed not to have words that would fully
express their sense of his despicable meanness, not to say turpitude.

Four years later I was again in Paris, and attended a meeting of
the Academy of Sciences.  In the course of the session a rustle
of attention spread over the room, as all eyes were turned upon
a member who was entering rather late.  Looking toward the door,
I saw a man of sixty, a decided blond, with light chestnut hair
turning gray, slender form, shaven face, rather pale and thin, but
very attractive, and extremely intellectual features.  As he passed
to his seat hands were stretched out on all sides to greet him, and
not until he sat down did the bustle caused by his entrance subside.
He was evidently a notable.

"Who is that?" I said to my neighbor.

"Leverrier."

Delaunay was one of the most kindly and attractive men I ever met.
We spent our evenings walking in the grounds of the observatory,
discussing French science in all its aspects.  His investigation
of the moon's motion is one of the most extraordinary pieces of
mathematical work ever turned out by a single person.  It fills two
quarto volumes, and the reader who attempts to go through any part
of the calculations will wonder how one man could do the work in
a lifetime.  His habit was to commence early in the morning, and
work with but little interruption until noon.  He never worked in
the evening, and generally retired at nine.  I felt some qualms of
conscience at the frequency with which I kept him up till nearly ten.
I found it hopeless to expect that he would ever visit America,
because he assured me that he did not dare to venture on the ocean.
The only voyage he had ever made was across the Channel, to receive
the gold medal of the Royal Astronomical Society for his work.
Two of his relatives--his father and, I believe, his brother--had
been drowned, and this fact gave him a horror of the water.
He seemed to feel somewhat like the clients of the astrologists,
who, having been told from what agencies they were to die, took every
precaution to avoid them.  I remember, as a boy, reading a history of
astrology, in which a great many cases of this sort were described;
the peculiarity being that the very measures which the victim took
to avoid the decree of fate became the engines that executed it.
The death of Delaunay was not exactly a case of this kind, yet it
could not but bring it to mind.  He was at Cherbourg in the autumn
of 1872.  As he was walking on the beach with a relative, a couple
of boatmen invited them to take a sail.  Through what inducement
Delaunay was led to forget his fears will never be known.  All we
know is that he and his friend entered the boat, that it was struck
by a sudden squall when at some distance from the land, and that
the whole party were drowned.

There was no opposition to the reappointment of Leverrier to his old
place.  In fact, at the time of my visit, Delaunay said that President
Thiers was on terms of intimate friendship with the former director,
and he thought it not at all unlikely that the latter would succeed
in being restored.  He kept the position with general approval till
his death in 1877.

The only occasion on which I met Leverrier was after the incident
I have mentioned, in the Academy of Sciences.  I had been told that
he was incensed against me on account of an unfortunate remark I had
made in speaking of his work which led to the discovery of Neptune.
I had heard this in Germany as well as in France, yet the matter was
so insignificant that I could hardly conceive of a man of philosophic
mind taking any notice of it.  I determined to meet him, as I had
met Hansen, with entire unconsciousness of offense.  So I called
on him at the observatory, and was received with courtesy, but no
particular warmth.  I suggested to him that now, as he had nearly
completed his work on the tables of the planets, the question of
the moon's motion would be the next object worthy of his attention.
He replied that it was too large a subject for him to take up.

To Leverrier belongs the credit of having been the real organizer of
the Paris Observatory.  His work there was not dissimilar to that
of Airy at Greenwich; but he had a much more difficult task before
him, and was less fitted to grapple with it.  When founded by Louis
XIV. the establishment was simply a place where astronomers of the
Academy of Sciences could go to make their observations.  There was
no titular director, every man working on his own account and in
his own way.  Cassini, an Italian by birth, was the best known of
the astronomers, and, in consequence, posterity has very generally
supposed he was the director.  That he failed to secure that honor
was not from any want of astuteness.  It is related that the monarch
once visited the observatory to see a newly discovered comet through
the telescope.  He inquired in what direction the comet was going to
move.  This was a question it was impossible to answer at the moment,
because both observations and computations would be necessary before
the orbit could be worked out.  But Cassini reflected that the king
would not look at the comet again, and would very soon forget what
was told him; so he described its future path in the heavens quite
at random, with entire confidence that any deviation of the actual
motion from his prediction would never be noted by his royal patron.

One of the results of this lack of organization has been that the
Paris Observatory does not hold an historic rank correspondent to
the magnificence of the establishment.  The go-as-you-please system
works no better in a national observatory than it would in a business
institution.  Up to the end of the last century, the observations
made there were too irregular to be of any special importance.
To remedy this state of things, Arago was appointed director early in
the present century; but he was more eminent in experimental physics
than in astronomy, and had no great astronomical problem to solve.
The result was that while he did much to promote the reputation of
the observatory in the direction of physical investigation, he did
not organize any well-planned system of regular astronomical work.

When Leverrier succeeded Arago, in 1853, he had an extremely difficult
problem before him.  By a custom extending through two centuries,
each astronomer was to a large extent the master of his own work.
Leverrier undertook to change all this in a twinkling, and, if reports
are true, without much regard to the feelings of the astronomers.
Those who refused to fall into line either resigned or were driven
away, and their places were filled with men willing to work under the
direction of their chief.  Yet his methods were not up to the times;
and the work of the Paris Observatory, so far as observations of
precision go, falls markedly behind that of Greenwich and Pulkova.

In recent times the institution has been marked by an energy and a
progressiveness that go far to atone for its former deficiencies.
The successors of Leverrier have known where to draw the line
between routine, on the one side, and initiative on the part of the
assistants, on the other.  Probably no other observatory in the world
has so many able and well-trained young men, who work partly on their
own account, and partly in a regular routine.  In the direction of
physical astronomy the observatory is especially active, and it may
be expected in the future to justify its historic reputation.




XII

THE OLD AND THE NEW WASHINGTON


A few features of Washington as it appeared during the civil war
are indelibly fixed in my memory.  An endless train of army wagons
ploughed its streets with their heavy wheels.  Almost the entire
southwestern region, between the War Department and the Potomac,
extending west on the river to the neighborhood of the observatory,
was occupied by the Quartermaster's and Subsistence Departments for
storehouses.  Among these the astronomers had to walk by day and
night, in going to and from their work.  After a rain, especially
during winter and spring, some of the streets were much like shallow
canals.  Under the attrition of the iron-bound wheels the water
and clay were ground into mud, which was at first almost liquid.
It grew thicker as it dried up, until perhaps another rainstorm
reduced it once more to a liquid condition.  In trying first one
street and then another to see which offered the fewest obstacles
to his passage, the wayfarer was reminded of the assurance given
by a bright boy to a traveler who wanted to know the best road to
a certain place: "Whichever road you take, before you get halfway
there you'll wish you had taken t' other."  By night swarms of rats,
of a size proportional to their ample food supply, disputed the
right of way with the pedestrian.

Across the Potomac, Arlington Heights were whitened by the tents of
soldiers, from which the discharges of artillery or the sound of the
fife and drum became so familiar that the dweller almost ceased to
notice it.  The city was defended by a row of earthworks, generally
not far inside the boundary line of the District of Columbia,
say five or six miles from the central portions of the city.
One of the circumstances connected with their plans strikingly
illustrates the exactness which the science or art of military
engineering had reached.  Of course the erection of fortifications
was one of the first tasks to be undertaken by the War Department.
Plans showing the proposed location and arrangements of the several
forts were drawn up by a board of army engineers, at whose head,
then or afterward, stood General John G. Barnard.  When the plans
were complete, it was thought advisable to test them by calling in the
advice of Professor D. H. Mahan of the Military Academy at West Point.
He came to Washington, made a careful study of the maps and plans,
and was then driven around the region of the lines to be defended
to supplement his knowledge by personal inspection.  Then he laid
down his ideas as to the location of the forts.  There were but
two variations from the plans proposed by the Board of Engineers,
and these were not of fundamental importance.

Willard's Hotel, then the only considerable one in the neighborhood of
the executive offices, was a sort of headquarters for arriving army
officers, as well as for the thousands of civilians who had business
with the government, and for gossip generally.  Inside its crowded
entrance one could hear every sort of story, of victory or disaster,
generally the latter, though very little truth was ever to be gleaned.

The newsboy flourished.  He was a bright fellow too, and may have
developed into a man of business, a reporter, or even an editor.
"Another great battle!" was his constant cry.  But the purchaser of
his paper would commonly read of nothing but a skirmish or some fresh
account of a battle fought several days before--perhaps not even this.
On one occasion an officer in uniform, finding nothing in his paper
to justify the cry, turned upon the boy with the remark,--

"Look here, boy, I don't see any battle here."

"No," was the reply, "nor you won't see one as long as you hang around
Washington.  If you want to see a battle you must go to the front."

The officer thought it unprofitable to continue the conversation,
and beat a retreat amid the smiles of the bystanders.  This story,
I may remark, is quite authentic, which is more than one can say
of the report that a stick thrown by a boy at a dog in front of
Willard's Hotel struck twelve brigadier generals during its flight.

The presiding genius of the whole was Mr. Edwin M. Stanton, Secretary
of War.  Before the actual outbreak of the conflict he had been,
I believe, at least a Democrat, and, perhaps, to a certain extent,
a Southern sympathizer so far as the slavery question was concerned.
But when it came to blows, he espoused the side of the Union, and
after being made Secretary of War he conducted military operations
with a tireless energy, which made him seem the impersonation of
the god of war.  Ordinarily his character seemed almost savage
when he was dealing with military matters.  He had no mercy on
inefficiency or lukewarmness.  But his sympathetic attention, when
a case called for it, is strikingly shown in the following letter,
of which I became possessed by mere accident.  At the beginning of
the war Mr. Charles Ellet, an eminent engineer, then resident near
Washington, tendered his services to the government, and equipped
a fleet of small river steamers on the Mississippi under the War
Department.  In the battle of June 6, 1862, he received a wound from
which he died some two weeks later.  His widow sold or leased his
house on Georgetown Heights, and I boarded in it shortly afterward.
Amongst some loose rubbish and old papers lying around in one of
the rooms I picked up the letter which follows.

    War Department,
   Washington City, D. C., June 9, 1862.

 Dear Madam,--I understand from Mr. Ellet's dispatch to you
 that as he will be unfit for duty for some time it will be
 agreeable to him for you to visit him, traveling slowly so
 as not to expose your own health.

 With this view I will afford you every facility within
 the control of the Department, by way of Pittsburg and
 Cincinnati to Cairo, where he will probably meet you.

  Yours truly,
   Edwin M. Stanton,
    _Secretary of War._

The interesting feature of this letter is that it is entirely in the
writer's autograph, and bears no mark of having been press copied.
I infer that it was written out of office hours, after all the clerks
had left the Department, perhaps late at night, while the secretary
was taking advantage of the stillness of the hour to examine papers
and plans.

Only once did I come into personal contact with Mr. Stanton.
A portrait of Ferdinand R. Hassler, first superintendent of the
Coast Survey, had been painted about 1840 by Captain Williams of the
Corps of Engineers, U. S. A., a son-in-law of Mr. G. W. P. Custis,
and therefore a brother-in-law of General Lee.  The picture at the
Arlington house was given to Mrs. Colonel Abert, who loaned it to
Mr. Custis.  When the civil war began she verbally donated it to
my wife, who was Mr. Hassler's grand-daughter, and was therefore
considered the most appropriate depositary of it, asking her to get
it if she could.  But before she got actual possession of it, the
Arlington house was occupied by our troops and Mr. Stanton ordered the
picture to be presented to Professor Agassiz for the National Academy
of Sciences.  On hearing of this, I ventured to mention the matter
to Mr. Stanton, with a brief statement of our claims upon the picture.

"Sir," said he, "that picture was found in the house of a rebel
in arms [General Robert E. Lee], and was justly a prize of war.
I therefore made what I considered the most appropriate disposition
of it, by presenting it to the National Academy of Sciences."

The expression "house of a rebel in arms" was uttered with such
emphasis that I almost felt like one under suspicion of relations
with the enemy in pretending to claim the object in question.
It was clearly useless to pursue the matter any further at that time.
Some years later, when the laws were no longer silent, the National
Academy decided that whoever might be the legal owner of the picture,
the Academy could have no claim upon it, and therefore suffered it
to pass into the possession of the only claimant.

Among the notable episodes of the civil war was the so-called raid
of the Confederate general, Early, in July, 1864.  He had entered
Maryland and defeated General Lew Wallace.  This left nothing but
the well-designed earthworks around Washington between his army
and our capital.  Some have thought that, had he immediately made
a rapid dash, the city might have fallen into his hands.

All in the service of the War and Navy departments who were supposed
capable of rendering efficient help, were ordered out to take part
in the defense of the city, among them the younger professors of the
observatory.  By order of Captain Gilliss I became a member of a naval
brigade, organized in the most hurried manner by Admiral Goldsborough,
and including in it several officers of high and low rank.  The rank
and file was formed of the workmen in the Navy Yard, most of whom
were said to have seen military service of one kind or another.
The brigade formed at the Navy Yard about the middle of the afternoon,
and was ordered to march out to Fort Lincoln, a strong earthwork built
on a prominent hill, half a mile southwest of the station now known
as Rives.  The Reform School of the District of Columbia now stands
on the site of the fort.  The position certainly looked very strong.
On the right the fort was flanked by a deep intrenchment running along
the brow of the hill, and the whole line would include in the sweep
of its fire the region which an army would have to cross in order
to enter the city.  The naval brigade occupied the trench, while
the army force, which seemed very small in numbers, manned the front.

I was not assigned to any particular duty, and simply walked round the
place in readiness to act whenever called upon.  I supposed the first
thing to be done was to have the men in the trench go through some
sort of drill, in order to assure their directing the most effective
fire on the enemy should he appear.  The trench was perhaps six feet
deep; along its bottom ran a little ledge on which the men had to
step in order to deliver their fire, stepping back into the lower
depth to load again.  Along the edge was a sort of rail fence, the
bottom rail of which rested on the ground.  In order to fire on an
enemy coming up the hill, it would be necessary to rest the weapon
on this bottom rail.  It was quite evident to me that a man not
above the usual height, standing on the ledge, would have to stand
on tiptoe in order to get the muzzle of his gun properly directed
down the slope.  If he were at all flurried he would be likely to
fire over the head of the enemy.  I called attention to this state
of things, but did not seem to make any impression on the officers,
who replied that the men had seen service and knew what to do.

We bivouacked that night, and remained all the next day and the night
following awaiting the attack of the enemy, who was supposed to be
approaching Fort Stevens on the Seventh Street road.  At the critical
moment, General H. G. Wright arrived from Fort Monroe with his
army corps.  He and General A. McD. McCook both took their stations
at Fort Lincoln, which it was supposed would be the point of attack.
A quarter or half a mile down the hill was the mansion of the Rives
family, which a passenger on the Baltimore and Ohio Railway can
readily see at the station of that name.  A squad of men was detailed
to go to this house and destroy it, in case the enemy should appear.
The attack was expected at daybreak, but General Early, doubtless
hearing of the arrival of reinforcements, abandoned any project
he might have entertained and had beat a retreat the day before.
Whether the supposition that he could have taken the city with great
celerity has any foundation, I cannot say; I should certainly greatly
doubt it, remembering the large loss of life generally suffered
during the civil war by troops trying to storm intrenchments or
defenses of any sort, even with greatly superior force.

I was surprised to find how quickly one could acquire the stolidity
of the soldier.  During the march from the Navy Yard to the fort
I felt extremely depressed, as one can well imagine, in view of
the suddenness with which I had to take leave of my family and
the uncertainty of the situation, as well as its extreme gravity.
But this depression wore off the next day, and I do not think I
ever had a sounder night's sleep in my life than when I lay down on
the grass, with only a blanket between myself and the sky, with the
expectation of being awakened by the rattle of musketry at daybreak.

I remember well how kindly we were treated by the army.
The acquaintance of Generals Wright and McCook, made under such
circumstances, was productive of a feeling which has never worn off.
It has always been a matter of sorrow to me that the Washington of
to-day does not show a more lively consciousness of what it owes to
these men.


One of the entertainments of Washington during the early years of
the civil war was offered by President Lincoln's public receptions.
We used to go there simply to see the people and the costumes, the
latter being of a variety which I do not think was ever known on
such occasions before or since.  Well-dressed and refined ladies and
gentlemen, men in their working clothes, women arrayed in costumes
fanciful in cut and brilliant in color, mixed together in a way
that suggested a convention of the human race.  Just where the
oddly dressed people came from, or what notion took them at this
particular time to don an attire like that of a fancy-dress ball,
no one seemed to know.

Among the never-to-be-forgotten scenes was that following the news of
the fall of Richmond.  If I described it from memory, a question would
perhaps arise in the reader's mind as to how much fancy might have
added to the picture in the course of nearly forty years.  I shall
therefore quote a letter written to Chauncey Wright immediately
afterwards, of which I preserved a press copy.

    Observatory, April 7, 1865.

 Dear Wright,--Yours of the 5th just received.  I heartily
 reciprocate your congratulations on the fall of Richmond
 and the prospective disappearance of the S. C. alias C. S.

 You ought to have been here Monday.  The observatory is half
 a mile to a mile from the thickly settled part of the city.
 At 11 A. M. we were put upon the qui vive by an unprecedented
 commotion in the city.  From the barracks near us rose a
 continuous stream of cheers, and in the city was a hubbub
 such as we had never before heard.  We thought it must be
 Petersburg or Richmond, but hardly dared to hope which.
 Miss Gilliss sent us word that it was really Richmond.
 I went down to the city.  All the bedlams in creation broken
 loose could not have made such a scene.  The stores were
 half closed, the clerks given a holiday, the streets
 crowded, every other man drunk, and drums were beating
 and men shouting and flags waving in every direction.
 I never felt prouder of my country than then, as I compared
 our present position with our position in the numerous dark
 days of the contest, and was almost ashamed to think that
 I had ever said that any act of the government was not the
 best possible.

Not many days after this outburst, the city was pervaded by an equally
intense and yet deeper feeling of an opposite kind.  Probably no
event in its history caused such a wave of sadness and sympathy as
the assassination of President Lincoln, especially during the few
days while bands of men were scouring the country in search of the
assassin.  One could not walk the streets without seeing evidence of
this at every turn.  The slightest bustle, perhaps even the running
away of a dog, caused a tremor.

I paid one short visit to the military court which was trying
the conspirators.  The court itself was listening with silence and
gravity to the reading of the testimony taken on the day previous.
General Wallace produced on the spectators an impression a little
different from the other members, by exhibiting an artistic
propensity, which subsequently took a different direction in
"Ben Hur."  The most impressive sight was that of the conspirators,
all heavily manacled; even Mrs. Surratt, who kept her irons partly
concealed in the folds of her gown.  Payne, the would-be assassin of
Seward, was a powerful-looking man, with a face that showed him ready
for anything; but the other two conspirators were such simple-minded,
mild-looking youths, that it seemed hardly possible they could have
been active agents in such a crime, or capable of any proceeding
requiring physical or mental force.

The impression which I gained at the time from the evidence and
all the circumstances, was that the purpose of the original plot
was not the assassination of the President, but his abduction and
transportation to Richmond or some other point within the Confederate
lines.  While Booth himself may have meditated assassination from the
beginning, it does not seem likely that he made this purpose known
to his fellows until they were ready to act.  Then Payne alone had
the courage to attempt the execution of the programme.

Two facts show that a military court, sitting under such
circumstances, must not be expected to reach exactly the verdict that
a jury would after the public excitement had died away.  Among the
prisoners was the man whose business it was to assist in arranging the
scenery on the stage of the theatre where the assassination occurred.
The only evidence against him was that he had not taken advantage
of his opportunity to arrest Booth as the latter was leaving,
and for this he was sentenced to twenty years penal servitude.
He was pardoned out before a great while.

The other circumstance was the arrest of Surratt, who was supposed
to stand next to Booth in the conspiracy, but who escaped from the
country and was not discovered until a year or so later, when he
was found to have enlisted in the papal guards at Rome.  He was
brought home and tried twice.  On the first trial, notwithstanding
the adverse rulings and charge of the judge, only a minority of
the jury were convinced of his guilt.  On the second trial he was,
I think, acquitted.

One aftermath of the civil war was the influx of crowds of the
newly freed slaves to Washington, in search of food and shelter.
With a little training they made fair servants if only their pilfering
propensities could be restrained.  But religious fervor did not ensure
obedience to the eighth commandment.  "The good Lord ain't goin'
to be hard on a poor darky just for takin' a chicken now and then,"
said a wench to a preacher who had asked her how she could reconcile
her religion with her indifference as to the ownership of poultry.

In the seventies I had an eight-year-old boy as help in my family.
He had that beauty of face very common in young negroes who have an
admixture of white blood, added to which were eyes of such depth and
clearness that, but for his color, he would have made a first-class
angel for a mediæval painter.

One evening my little daughters had a children's party, and Zeke
was placed as attendant in charge of the room in which the little
company met.  Here he was for some time left alone.  Next morning a
gold pen was missing from its case in a drawer.  Suspicion rested on
Zeke as the only person who could possibly have taken it, but there
was no positive proof.  I thought so small and innocent-looking a
boy could be easily cowed into confessing his guilt; so next morning
I said to him very solemnly,--

"Zeke, come upstairs with me."

He obeyed with alacrity, following me up to the room.

"Zeke, come into this room."

He did so.

"Now, Zeke," I said sternly, "look here and see what I do."

I opened the drawer, took out the empty case, opened it, and showed
it to him.

"Zeke, look into my eyes!"

He neither blinked nor showed the slightest abashment or hesitation
as his soft eyes looked steadily into mine with all the innocence
of an angel.

"Zeke, where is the pen out of that case?"

"Missr Newcomb," he said quietly, "I don't know nothin' about it."

I repeated the question, looking into his face as sternly as I could.
As he repeated the answer with the innocence of childhood, "Deed,
Missr Newcomb, I don't know what was in it," I felt almost like a
brute in pressing him with such severity.  Threats were of no avail,
and I had to give the matter up as a failure.

On coming home in the afternoon, the first news was that the pen had
been found by Zeke's mother hidden in one corner of her room at home,
where the little thief had taken it.  She, being an honest woman,
and suspecting where it had come from, had brought it back.


There was a vigorous movement, having its origin in New England,
for the education of the freedmen.  This movement was animated by
the most philanthropic views.  Here were several millions of blacks
of all ages, suddenly made citizens, or eligible to citizenship,
and yet savage so far as any education was concerned.  A small army
of teachers, many, perhaps most of them, young women, were sent south
to organize schools for the blacks.  It may be feared that there was
little adaptation of the teaching to the circumstances of the case.
But one method of instruction widely adopted was, so far as I can
learn, quite unique.  It was the "loud method" of teaching reading
and spelling.  The whole school spelled in unison.  The passer-by
on the street would hear in chorus from the inside of the building,
"B-R-E-A-D--BREAD!" all at the top of the voice of the speakers.
Schools in which this method was adopted were known as "loud schools."

A queer result of this movement once fell under my notice.  I called
at a friend's house in Georgetown.  In the course of the conversation,
it came out that the sable youngster who opened the door for me
filled the double office of scullion to the household and tutor in
Latin to the little boy of the family.


Probably the Senate of the United States never had a member more
conscientious in the discharge of his duties than Charles Sumner.
He went little into society outside the circles of the diplomatic
corps, with which his position as chairman of the Foreign Affairs
Committee placed him in intimate relations.  My acquaintance with
him arose from the accident of his living for some time almost
opposite me.  I was making a study of some historic subject,
pertaining to the feeling in South Carolina before the civil war,
and called at his rooms to see if he would favor me with the loan of
a book, which I was sure he possessed.  He received me so pleasantly
that I was, for some time, an occasional visitor.  He kept bachelor
quarters on a second floor, lived quite alone, and was accessible
to all comers without the slightest ceremony.

One day, while I was talking with him, shortly after the surrender
of Lee, a young man in the garb of a soldier, evidently fresh from
the field, was shown into the room by the housemaid, unannounced,
as usual.  Very naturally, he was timid and diffident in approaching
so great a man, and the latter showed no disposition to say anything
that would reassure him.  He ventured to tell the senator that he
had come to see if he could recommend him for some public employment.
I shall never forget the tone of the reply.

"But _I_ do not know _you_."  The poor fellow was completely
dumfounded, and tried to make some excuses, but the only reply he
got was, "I cannot do it; I do not know you at all."  The visitor
had nothing to do but turn round and leave.

At the time I felt some sympathy with the poor fellow.  He had
probably come, thinking that the great philanthropist was quite ready
to become a friend to a Union soldier without much inquiry into his
personality and antecedents, and now he met with a stinging rebuff.
But it must be confessed that subsequent experience has diminished
my sympathy for him, and probably it would be better for the country
if the innovation were introduced of having every senator of the
United States dispose of such callers in the same way.

Foreign men of letters, with whom Sumner's acquaintance was very
wide, were always among his most valued guests.  A story is told
of Thackeray's visit to Washington, which I distrust only for the
reason that my ideas of Sumner's make-up do not assign him the
special kind of humor which the story brings out.  He was, however,
quoted as saying, "Thackeray is one of the most perfect gentlemen
I ever knew.  I had a striking illustration of that this morning.
We went out for a walk together and, thoughtlessly, I took him
through Lafayette Square.  Shortly after we entered it, I realized
with alarm that we were going directly toward the Jackson statue.
It was too late to retrace our steps, and I wondered what Thackeray
would say when he saw the object.  But he passed straight by without
seeming to see it at all, and did not say one word about it."

Sumner was the one man in the Senate whose seat was scarcely ever
vacant during a session.  He gave the closest attention to every
subject as it arose.  One instance of this is quite in the line of the
present book.  About 1867, an association was organized in Washington
under the name of the "American Union Academy of Literature, Science,
and Art."  Its projectors were known to few, or none, but themselves.
A number of prominent citizens in various walks of life had been
asked to join it, and several consented without knowing much about
the association.  It soon became evident that the academy was desirous
of securing as much publicity as possible through the newspapers
and elsewhere.  It was reported that the Secretary of the Treasury
had asked its opinion on some instrument or appliance connected
with the work of his department.  Congress was applied to for an
act of incorporation, recognizing it as a scientific adviser of the
government by providing that it should report on subjects submitted
to it by the governmental departments, the intent evidently being
that it should supplant the National Academy of Sciences.

The application to Congress satisfied the two requirements most
essential to favorable consideration.  These are that several
respectable citizens want something done, and that there is no one to
come forward and say that he does not want it done.  Such being the
case, the act passed the House of Representatives without opposition,
came to the Senate, and was referred to the appropriate committee,
that on education, I believe.  It was favorably reported from the
committee and placed on its passage.  Up to this point no objection
seems to have been made to it in any quarter.  Now, it was challenged
by Mr. Sumner.

The ground taken by the Massachusetts senator was comprehensive
and simple, though possibly somewhat novel.  It was, in substance,
that an academy of literature, science, and art, national in its
character, and incorporated by special act of Congress, ought to be
composed of men eminent in the branches to which the academy related.
He thought a body of men consisting very largely of local lawyers,
with scarcely a man of prominence in either of the three branches to
which the academy was devoted, was not the one that should receive
such sanction from the national legislature.

Mr. J. W. Patterson, of New Hampshire, was the principal advocate
of the measure.  He claimed that the proposed incorporators were
not all unscientific men, and cited as a single example the name of
O. M. Poe, which appeared among them.  This man, he said, was a very
distinguished meteorologist.

This example was rather unfortunate.  The fact is, the name in
question was that of a well-known officer of engineers in the
army, then on duty at Washington, who had been invited to join the
academy, and had consented out of good nature without, it seems,
much if any inquiry.  It happened that Senator Patterson had, some
time during the winter, made the acquaintance of a West Indian
meteorologist named Poey, who chanced to be spending some time in
Washington, and got him mixed up with the officer of engineers.
The senator also intimated that the gentleman from Massachusetts had
been approached on the subject and was acting under the influence
of others.  This suggestion Mr. Sumner repelled, stating that no one
had spoken to him on the subject, that he knew nothing of it until
he saw the bill before them, which seemed to him to be objectionable
for the very reasons set forth.  On his motion the bill was laid on
the table, and thus disposed of for good.  The academy held meetings
for some time after this failure, but soon disappeared from view,
and was never again heard of.


In the year 1862, a fine-looking young general from the West became
a boarder in the house where I lived, and sat opposite me at table.
His name was James A. Garfield.  I believe he had come to Washington
as a member of the court in the case of General Fitz John Porter.
He left after a short time and had, I supposed, quite forgotten
me.  But, after his election to Congress, he one evening visited
the observatory, stepped into my room, and recalled our former
acquaintance.

I soon found him to be a man of classical culture, refined tastes,
and unsurpassed eloquence,--altogether, one of the most attractive of
men.  On one occasion he told me one of his experiences in the State
legislature of Ohio, of which he was a member before the civil war.
A bill was before the House enacting certain provisions respecting
a depository.  He moved, as an amendment, to strike out the word
"depository" and insert "depositary."  Supposing the amendment to
be merely one of spelling, there was a general laugh over the house,
with a cry of "Here comes the schoolmaster!"  But he insisted on his
point, and sent for a copy of Webster's Dictionary in order that the
two words might be compared.  When the definitions were read, the
importance of right spelling became evident, and the laughing stopped.

It has always seemed to me that a rank injustice was done to Garfield
on the occasion of the Credit Mobilier scandal of 1873, which came
near costing him his position in public life.  The evidence was of
so indefinite and flimsy a nature that the credence given to the
conclusion from it can only illustrate how little a subject or a
document is exposed to searching analysis outside the precincts of a
law court.  When he was nominated for the presidency this scandal was
naturally raked up and much made of it.  I was so strongly impressed
with the injustice as to write for a New York newspaper, anonymously
of course, a careful analysis of the evidence, with a demonstration
of its total weakness.  Whether the article was widely circulated,
or whether Garfield ever heard of it, I do not know; but it was
amusing, a few days after it appeared, to see a paragraph in an
opposition paper claiming that its contemporary had gone to the
trouble of hiring a lawyer to defend Garfield.

No man better qualified as a legislator ever occupied a seat in
Congress.  A man cast in the largest mould, and incapable of a petty
sentiment, his grasp of public affairs was rarely equaled, and his
insight into the effects of legislation was of the deepest.  But on
what the author of the Autocrat calls the arithmetical side,--in
the power of judging particular men and not general principles; in
deciding who were the good men and who were not, he fell short of the
ideal suggested by his legislative career.  The brief months during
which he administered the highest of offices were stormy enough,
perhaps stormier than any president before him had ever experienced,
and they would probably have been outdone by the years following,
had he lived.  But I believe that, had he remained in the Senate,
his name would have gone into history among those of the greatest
of legislators.

Sixteen years after the death of Lincoln public feeling was again
moved to its depth by the assassination of Garfield.  The cry
seemed to pass from mouth to mouth through the streets faster than
a messenger could carry the news, "The President has been shot."
It chanced to reach me just as I was entering my office.  I at once
summoned my messenger and directed him to go over to the White House,
and see if anything unusual had happened, but gave him no intimation
of my fears.  He promptly returned with the confirmation of the
report.  The following are extracts from my journal at the time:--

 "July 2, Saturday: At 9.20 this morning President Garfield
 was shot by a miserable fellow named Guiteau, as he was
 passing through the Baltimore and Potomac R. R. station to
 leave Washington.  One ball went through the upper arm,
 making a flesh wound, the other entered the right side
 on the back and cannot be found; supposed to have lodged
 in the liver.  In the course of the day President rapidly
 weakened, and supposed to be dying from hemorrhage."

 "Sunday morning: President still living and rallied during
 the day.  Small chance of recovery.  At night alarming
 symptoms of inflammation were exhibited, and at midnight
 his case seemed almost hopeless."

 "Monday: President slightly better this morning, improving
 throughout the day."

 "July 6.  This P. M. sought an interview with Dr. Woodward
 at the White House, to talk of an apparatus for locating
 the ball by its action in retarding a rapidly revolving
 el. magnet.  I hardly think the plan more than theoretically
 practical, owing to the minuteness of the action."

 "The President still improving, but great dangers are yet
 to come, and nothing has been found of the ball, which
 is supposed to have stayed in the liver because, were it
 anywhere else, symptoms of irritation by its presence would
 have been shown."

 "July 9.  This is Saturday evening.  Met Major Powell at
 the Cosmos Club, who told me that they would like to have
 me look at the air-cooling projects at the White House.
 Published statement that the physicians desired some way to
 cool the air of the President's room had brought a crowd of
 projects and machines of all kinds.  Among other things,
 a Mr. Dorsey had got from New York an air compressor such
 as is used in the Virginia mines for transferring power,
 and was erecting machinery enough for a steamship at the
 east end of the house in order to run it."

Dr. Woodward was a surgeon of the army, who had been on duty at
Washington since the civil war, in charge of the Army Medical Museum.
Among his varied works here, that in micro-photography, in which
he was a pioneer, gave him a wide reputation.  His high standing
led to his being selected as one of the President's physicians.
To him I wrote a note, offering to be of any use I could in the
matter of cooling the air of the President's chamber.  He promptly
replied with a request to visit the place, and see what was being
done and what suggestions I could make.  Mr. Dorsey's engine at the
east end was dispensed with after a long discussion, owing to the
noise it would make and the amount of work necessary to its final
installation and operation.

Among the problems with which the surgeons had to wrestle was that
of locating the ball.  The question occurred to me whether it was
not possible to do so by the influence produced by the action of
a metallic conductor in retarding the motion of a rapidly revolving
magnet, but the effect would be so small, and the apparatus to be made
so delicate, that I was very doubtful about the matter.  If there
was any one able to take hold of the project successfully, I knew
it would be Alexander Graham Bell, the inventor of the telephone.
When I approached him on the subject, he suggested that the idea
of locating the ball had also occurred to him, and that he thought
the best apparatus for the purpose was a telephonic one which had
been recently developed by Mr. Hughes.  As there could be no doubt
of the superiority of his project, I dropped mine, and he went
forward with his.  In a few days an opportunity was given him for
actually trying it.  The result, though rather doubtful, seemed to
be that the ball was located where the surgeons supposed it to be.
When the autopsy showed that their judgment had been at fault,
Mr. Bell admitted his error to Dr. Woodward, adding some suggestion
as to its cause.  "Expectant attention," was Woodward's reply.

I found in the basement of the house an apparatus which had been
brought over by a Mr. Jennings from Baltimore, which was designed
to cool the air of dairies or apartments.  It consisted of an iron
box, two or three feet square, and some five feet long.  In this
box were suspended cloths, kept cool and damp by the water from
melting ice contained in a compartment on top of the box.  The air
was driven through the box by a blower, and cooled by contact with
the wet cloths.  But no effect was being produced on the temperature
of the room.

One conversant with physics will see one fatal defect in this
appliance.  The cold of the ice, if I may use so unscientific an
expression, went pretty much to waste.  The air was in contact,
not with the ice, as it should have been, but with ice-water, which
had already absorbed the latent heat of melting.

Evidently the air should be passed over the unmelted ice.
The question was how much ice would be required to produce the
necessary cooling?  To settle this, I instituted an experiment.
A block of ice was placed in an adjoining room in a current of
air with such an arrangement that, as it melted, the water would
trickle into a vessel below.  After a certain number of minutes
the melted water was measured, then a simple computation led to a
knowledge of how much heat was absorbed from the air per minute by
a square foot of the surface of the ice.  From this it was easy to
calculate from the known thermal capacity of air, and the quantity
of the latter necessary per minute, how many feet of cooling surface
must be exposed.  I was quite surprised at the result.  A case of
ice nearly as long as an ordinary room, and large enough for men
to walk about in it, must be provided.  This was speedily done,
supports were erected for the blocks of ice, the case was placed at
the end of Mr. Jennings's box, and everything gotten in readiness
for directing the air current through the receptacle, and into the
room through tubes which had already been prepared.

It happened that Mr. Jennings's box was on the line along which the
air was being conducted, and I was going to get it out of the way.
The owner implored that it should be allowed to remain, suggesting
that the air might just as well as not continue to pass through it.
The surroundings were those in which one may be excused for not
being harsh.  Such an outpouring of sympathy on the part of the
public had never been seen in Washington since the assassination
of Lincoln.  Those in charge were overwhelmed with every sort of
contrivance for relieving the sufferings of the illustrious patient.
Such disinterested efforts in behalf of a public and patriotic
object had never been seen.  Mr. Jennings had gone to the trouble
and expense of bringing his apparatus all the way from Baltimore to
Washington in order to do what in him lay toward the end for which all
were striving.  To leave his box in place could not do the slightest
harm, and would be a gratification to him.  So I let it stand,
and the air continued to pass through it on its way to the ice chest.

While these arrangements were in progress three officers of engineers
of the navy reported under orders at the White House, to do what
they could toward the cooling of the air.  They were Messrs. William
L. Baillie, Richard Inch, and W. S. Moore.  All four of us coöperated
in the work in a most friendly way, and when we got through we made
our reports to the Navy Department.  A few weeks later these reports
were printed in a pamphlet, partly to correct a wrong impression
about the Jennings cold-box.  Regular statements had appeared in the
local evening paper that the air was being cooled by this useless
contrivance.  Their significance first came out several months
later, on the occasion of an exhibition of mechanical or industrial
implements at Boston.  Among these was Mr. Jennings's cold-box,
which was exhibited as the instrument that had cooled the air of
President Garfield's chamber.

More light yet was thrown on the case when the question of rewarding
those who had taken part in treating the President, or alleviating
his sufferings in any way, came before Congress.  Mr. Jennings was,
I believe, among the claimants.  Congress found the task of making
the proper awards to each individual to be quite beyond its power
at the time, so a lump sum was appropriated, to be divided by the
Treasury Department according to its findings in each particular case.
Before the work of making the awards was completed, I left on the
expedition to the Cape of Good Hope to observe the transit of Venus,
and never learned what had been done with the claims of Mr. Jennings.
It might naturally be supposed that when an official report to
the Navy Department showed that he had no claims whatever except
those of a patriotic citizen who had done his best, which was just
nothing at all, to promote the common end, the claim would have
received little attention.  Possibly this may have been the case.
But I do not know what the outcome of the matter was.

Shortly after the death of the President, I had a visit from an
inventor who had patented a method of cooling the air of a room
by ice.  He claimed that our work at the Executive Mansion was an
infringement on his patent.  I replied that I could not see how
any infringement was possible, because we had gone to work in the
most natural way, without consulting any previous process whatever,
or even knowing of the existence of a patent.  Surely the operation
of passing air over ice to cool it could not be patentable.

He invited me to read over the statement of his claims.  I found that
although this process was not patented in terms, it was practically
patented by claiming about every possible way in which ice could be
arranged for cooling purposes.  Placing the ice on supports was one
of his claims; this we had undoubtedly done, because otherwise the
process could not have been carried out.  In a word, the impression
I got was that the only sure way of avoiding an infringement would
have been to blindfold the men who put the ice in the box, and ask
them to throw it in pellmell.  Every method of using judgment in
arranging the blocks of ice he had patented.

I had to acknowledge that his claim of infringement might have
some foundation, and inquired what he proposed to do in the case.
He replied that he did not wish to do more than have his priority
recognized in the matter.  I replied that I had no objection to his
doing this in any way he could, and he took his leave.  Nothing more,
so far as I am aware, was done in his case.  But I was much impressed
by this as by other examples I have had of the same kind, of the
loose way in which our Patent Office sometimes grants patents.


I do not think the history of any modern municipality can show an
episode more extraordinary or, taken in connection with its results,
more instructive than what is known as the "Shepherd régime" in
Washington.  What is especially interesting about it is the opposite
views that can be taken of the same facts.  As to the latter there
is no dispute.  Yet, from one point of view, Shepherd made one of
the most disastrous failures on record in attempting to carry out
great works, while, from another point of view, he is the author of
the beautiful Washington of to-day, and entitled to a public statue
in recognition of his services.  As I was a resident of the city
and lived in my own house, I was greatly interested in the proposed
improvements, especially of the particular street on which I lived.
I was also an eye-witness to so much of the whole history as the
public was cognizant of.  The essential facts of the case, from the
two, opposing points of view, are exceedingly simple.

One fact is the discreditable condition of the streets of Washington
during and after the civil war.  The care of these was left entirely
to the local municipality.  Congress, so far as I know, gave no aid
except by paying its share of street improvements in front of the
public buildings.  It was quite out of the power of the residents,
who had but few men of wealth among them, to make the city what it
ought to be.  Congress showed no disposition to come to the help of
the citizens in this task.

In 1871, however, some public-spirited citizens took the matter in
hand and succeeded in having a new government established, which
was modeled after that of the territories of the United States.
There was a governor, a legislature, and a board of public works.
The latter was charged with the improvements of the streets, and
the governor was _ex officio_ its president.  The first governor was
Henry D. Cooke, the banker, and Mr. Shepherd was vice-president of
the board of public works and its leading member.  Mr. Cooke resigned
after a short term, and Mr. Shepherd was promoted to his place.
He was a plumber and gas-fitter by trade, and managed the leading
business in his line in Washington.  Through the two or three years
of his administration the city directory still contained the entry--

Shepherd, Alex. R. & Co., plumbers and gas-fitters, 910 Pa. Ave. N. W.

In recent years he had added to his plumbing business that of erecting
houses for sale.  He had had no experience in the conduct of public
business, and, of course, was neither an engineer nor a financier.
But such was the energy of his character and his personal influence,
that he soon became practically the whole government, which he ran in
his own way, as if it were simply his own business enlarged.  Of the
conditions which the law imposes on contracts, of the numerous and
complicated problems of engineering involved in the drainage and
street systems of a great city, of the precautions to be taken in
preparing plans for so immense a work, and of the legal restraints
under which it should be conducted, he had no special knowledge.
But he had in the highest degree a quality which will bear different
designations according to the point of view.  His opponents would call
it unparalleled recklessness; his supporters, boldness and enterprise.

Such were the preliminaries.  Three years later the results of his
efforts were made known by an investigating committee of Congress,
with Senator Allison, a political friend, at its head.  It was
found that with authority to expend $6,000,000 in the improvement
of the streets, there was an actual or supposed expenditure of
more than $18,000,000, and a crowd of additional claims which no
man could estimate, based on the work of more than one thousand
principal contractors and an unknown number of purchasers and
sub-contractors.  Chaos reigned supreme.  Some streets were still
torn up and impassable; others completely paved, but done so badly
that the pavements were beginning to rot almost before being pressed
by a carriage.  A debt had been incurred which it was impossible
for the local municipality to carry and which was still piling up.

For all this Congress was responsible, and manfully shouldered
its responsibility.  Mr. Shepherd was legislated out of office as
an act of extreme necessity, by the organization of a government
at the head of which were three commissioners.  The feeling on the
subject may be inferred from the result when President Grant, who
had given Shepherd his powerful support all through, nominated him as
one of the three commissioners.  The Senate rejected the nomination,
with only some half dozen favorable votes.

The three commissioners took up the work and carried it on in a
conservative way.  Congress came to the help of the municipality by
bearing one half the taxation of the District, on the very sound
basis that, as it owned about one half of the property, it should
pay one half the taxes.

The spirit of the time is illustrated by two little episodes.
The reservation on which the public library founded by Mr. Carnegie
is now built, was then occupied by the Northern Liberties Market,
one of the three principal markets of the city.  Being a public
reservation, it had no right to remain there except during the
pleasure of the authorities.  Due notice was given to the marketmen
to remove the structures.  The owners were dilatory in doing so, and
probably could not see why they should be removed when the ground was
not wanted for any other purpose, and before they had time to find
a new location.  It was understood that, if an attempt was made to
remove the buildings, the marketmen would apply to the courts for
an injunction.  To prevent this, an arrangement was made by which
the destruction of the buildings was to commence at dinner-time.
At the same time, according to current report, it was specially
arranged that all the judges to whom an application could be made
should be invited out to dinner.  However this may have been, a large
body of men appeared upon the scene in the course of the evening
and spent the night in destroying the buildings.  With such energy
was the work carried on that one marketman was killed and another
either wounded or seriously injured in trying to save their wares
from destruction.  The indignation against Shepherd was such that
his life was threatened, and it was even said that a body-guard of
soldiers had to be supplied by the War Department for his protection.

The other event was as comical as this was tragic.  It occurred
while the investigating committee of Congress was at its work.
The principal actors in the case were Mr. Harrington, secretary
of the local government and one of Mr. Shepherd's assistants, the
chief of police, and a burglar.  Harrington produced an anonymous
letter, warning him that an attempt would be made in the course of
a certain night to purloin from the safe in which they were kept,
certain government papers, which the prosecutors of the case against
Shepherd were anxious to get hold of.  He showed this letter to
the chief of police, who was disposed to make light of the matter.
But on Harrington's urgent insistence the two men kept watch about the
premises on the night in question.  They were in the room adjoining
that in which the records were kept, and through which the robber
would have to pass.  In due time the latter appeared, passed through
the room and proceeded to break into the safe.  The chief wanted to
arrest him immediately, but Harrington asked him to wait, in order
that they might see what the man was after, and especially what he
did with the books.  So they left and took their stations outside
the door.  The burglar left the building with the books in a satchel,
and, stepping outside, was confronted by the two men.

I believe every burglar of whom history or fiction has kept any
record, whether before or after this eventful night, when he broke
open a safe and, emerging with his booty, found himself confronted by
a policeman, took to his heels.  Not so this burglar.  He walked up
to the two men, and with the utmost unconcern asked if they could
tell him where Mr. Columbus Alexander lived.  Mr. Alexander, it
should be said, was the head man in the prosecution.  The desired
information being conveyed to the burglar, he went on his way
to Mr. Alexander's house, followed by the two agents of the law.
Arriving there, he rang the bell.

In the ordinary course of events, Mr. Alexander or some member of his
family would have come to the door and been informed that the caller
had a bundle for him.  A man just awakened from a sound sleep and
coming downstairs rubbing his eyes, would not be likely to ask any
questions of such a messenger, but would accept the bundle and lock
the door again.  Then what a mess the prosecution would have been in!
Its principal promoter detected in collusion with a burglar in order
to get possession of the documents necessary to carry on his case!

It happened, however, that Mr. Alexander and the members of his
household all slept the sleep of the just and did not hear the bell.
The patience of the policeman was exhausted and the burglar was
arrested and lodged in jail, where he was kept for several months.
Public curiosity to hear the burglar's story was brought to a
high pitch, but never gratified.  Before the case came to trial
the prisoner was released on straw bail and never again found.
I do not think the bottom facts, especially those connected with
the anonymous letter, were ever brought to light.  So every one
was left to form his own theory of what has since been known as the
"Safe Burglary Conspiracy."

What seems at present the fashionable way of looking at the facts
is this: Shepherd was the man who planned the beautiful Washington
of to-day, and who carried out his project with unexampled energy
until he was stopped through the clamor of citizens who did not
want to see things go ahead so fast.  Other people took the work up,
but they only carried out Shepherd's ideas.  The latter, therefore,
should have all the credit due to the founder of the new Washington.

The story has always seemed to me most interesting as an example
of the way in which public judgment of men and things is likely to
be influenced.  Public sentiment during the thirty years which have
since elapsed has undergone such a revolution in favor of Shepherd
that a very likely outcome will be a monument to commemorate his work.
But it is worth while to notice the mental processes by which the
public now reaches this conclusion.  It is the familiar and ordinarily
correct method of putting this and that together.

_This_ is one of the most beautiful cities in the United States,
of which Americans generally are proud when they pay it a visit.

_That_ is the recollection of the man who commenced the work of
transforming an unsightly, straggling, primitive town into the
present Washington, and was condemned for what he did.

These two considerations form the basis of the conclusion, all
intermediate details dropping out of sight and memory.  The reckless
maladministration of the epoch, making it absolutely necessary to
introduce a new system, has no place in the picture.

There is also a moral to the story, which is more instructive
than pleasant.  The actors in the case no doubt believed that if
they set about their work in a conservative and law-abiding way,
spending only as much money as could be raised, Congress would
never come to their help.  So they determined to force the game,
by creating a situation which would speedily lead to the correct
solution of the problem.  I do not think any observant person will
contest the proposition that had Shepherd gone about his work and
carried it to a successful conclusion in a peaceable and law-abiding
way,--had he done nothing to excite public attention except wisely
and successfully to administer a great public work,--his name would
now have been as little remembered in connection with what he did as
we remember those of Ketchem, Phelps, and the other men who repaired
the wreck he left and made the city what it is to-day.

In my mind one question dominates all others growing out of the
case: What will be the moral effect on our children of holding up
for their imitation such methods as I have described?




XIII

MISCELLANEA


If the "Great Star-Catalogue Case" is not surrounded with such mystery
as would entitle it to a place among _causes célèbres_, it may well
be so classed on account of the novelty of the questions at issue.
It affords an instructive example of the possibility of cases in
which strict justice cannot be done through the established forms
of legal procedure.  It is also of scientific interest because,
although the question was a novel one to come before a court, it
belongs to a class which every leader in scientific investigation
must constantly encounter in meting out due credit to his assistants.

The plaintiff, Christian H. F. Peters, was a Dane by birth, and
graduated at the University of Berlin in 1836.  During the earlier
years of his manhood he was engaged in the trigonometrical survey
of the kingdom of Naples, where, for a time, he had charge of an
observatory or some other astronomical station.  It is said that, like
many other able European youth of the period, he was implicated in
the revolution of 1848, and had to flee the kingdom in consequence.
Five years later, he came to the United States.  Here his first
patron was Dr. B. A. Gould, who procured for him first a position
on the Coast Survey, and then one as his assistant at the Dudley
Observatory in Albany.  He was soon afterward appointed professor
of astronomy and director of the Litchfield Observatory at Hamilton
College, where he spent the remaining thirty years of his life.
He was a man of great learning, not only in subjects pertaining
to astronomy, but in ancient and modern languages.  The means at
his disposal were naturally of the slenderest kind; but he was the
discoverer of some forty asteroids, and devoted himself to various
astronomical works and researches with great ability.

Of his personality it may be said that it was extremely agreeable so
long as no important differences arose.  What it would be in such a
case can be judged by what follows.  Those traits of character which
in men like him may be smoothed down to a greater or less extent
by marital discipline were, in the absence of any such agency,
maintained in all their strength to his latest years.

The defendant, Charles A. Borst, was a graduate of the college and had
been a favorite pupil of Peters.  He was a man of extraordinary energy
and working capacity, ready to take hold in a business-like way of
any problem presented to him, but not an adept at making problems for
himself.  His power of assimilating learning was unusually developed;
and this, combined with orderly business habits, made him a most
effective and valuable assistant.  The terms of his employment were
of the first importance in the case.  Mr. Litchfield of New York was
the patron of the observatory; he had given the trustees of Hamilton
College a capital for its support, which sufficed to pay the small
salary of the director and some current expenses, and he also, when
the latter needed an assistant, made provision for his employment.
It appears that, in the case of Borst, Peters frequently paid his
salary for considerable periods at a time, which sums were afterward
reimbursed to him by Mr. Litchfield.

I shall endeavor to state the most essential facts involved as they
appear from a combination of the sometimes widely different claims
of the two parties, with the hope of showing fairly what they were,
but without expecting to satisfy a partisan of either side.  Where an
important difference of statement is irreconcilable, I shall point
it out.

In his observations of asteroids Peters was continually obliged to
search through the pages of astronomical literature to find whether
the stars he was using in observation had ever been catalogued.
He long thought that it would be a good piece of work to search
all the astronomical journals and miscellaneous collections of
observations with a view of making a complete catalogue of the
positions of the thousands of stars which they contained, and
publishing it in a single volume for the use of astronomers situated
as he was.  The work of doing this was little more than one of routine
search and calculation, which any well-trained youth could take up;
but it was naturally quite without the power of Peters to carry it
through with his own hand.  He had employed at least one former
assistant on the work, Professor John G. Porter, but very little
progress was made.  Now, however, he had a man with the persistence
and working capacity necessary to carry out the plan.

There was an irreconcilable difference between the two parties as
to the terms on which Borst went to work.  According to the latter,
Peters suggested to him the credit which a young man would gain as
one of the motives for taking up the job.  But plaintiff denied
that he had done anything more than order him to do it.  He did
not, however, make it clear why an assistant at the Litchfield
Observatory should be officially ordered to do a piece of work for
the use of astronomy generally, and having no special connection
with the Litchfield Observatory.

However this may be, Borst went vigorously to work, repeating all the
calculations which had been made by Peters and former assistants,
with a view of detecting errors, and took the work home with him
in order that his sisters might make a great mass of supplementary
calculations which, though not involved in the original plan,
would be very conducive to the usefulness of the result.  One or
two of these bright young ladies worked for about a year at the job.
How far Peters was privy to what they did was not clear; according
to his claim he did not authorize their employment to do anything
but copy the catalogue.

By the joint efforts of the assistant and his two sisters,
working mostly or entirely at their own home, the work was
brought substantially to a conclusion about the beginning of 1888.
Borst then reported the completion to his chief and submitted a
proposed title-page, which represented that the work was performed
by Charles A. Borst under the direction of Christian H. F. Peters,
Professor of Astronomy, etc.  According to Borst's account, Peters
tore up the paper, opened the stove door, put the fragments into
the fire, and then turned on the assistant with the simple order,
"Bring me the catalogue!"

This was refused, and a suit in replevin was immediately instituted
by Peters.  The ablest counsel were engaged on both sides.  That of
the plaintiff was Mr. Elihu Root, of New York, afterward Secretary of
War, one of the leading members of the New York bar, and well known
as an active member of the reform branch of the Republican party of
that city.  For the defendant was the law firm of an ex-senator of
the United States, the Messrs. Kernan of Utica.

I think the taking of evidence and the hearing of arguments occupied
more than a week.  One claim of the defendant would, if accepted,
have brought the suit to a speedy end.  Peters was an employee
of the corporation of Hamilton College, and by the terms of his
appointment all his work at the Litchfield Observatory belonged to
that institution.  Borst was summoned into the case as an official
employee of the Litchfield Observatory.  Therefore the corporation of
the college was the only authority which had power to bring the suit.
But this point was disposed of by a decision of the judge that it was
not reasonable, in view of the low salary received by the plaintiff,
to deprive him of the right to the creations of his own talent.
He did not, however, apply this principle of legal interpretation to
the case of the defendant, and not only found for the plaintiff, but
awarded damages based on the supposed value of the work, including,
if I understand the case aright, the value of the work done by the
young ladies.  It would seem, however, that in officially perfecting
the details of his decision he left it a little indefinite as to
what papers the plaintiff was entitled to, it being very difficult
to describe in detail papers many of which he had never seen.
Altogether it may be feared that the decision treated the catalogue
much as the infant was treated by the decision of Solomon.

However this might he, the decision completely denied any right of
the defendant in the work.  This feature of it I thought very unjust,
and published in a Utica paper a review of the case in terms not quite
so judicial as I ought to have chosen.  I should have thought such a
criticism quite a breach of propriety, and therefore would never have
ventured upon it but for an eminent example then fresh in my mind.

Shortly after the Supreme Court of the United States uttered its
celebrated decision upholding the constitutionality of the Legal
Tender Act, I happened to be conversing at an afternoon reception
with one of the judges, Gray, who had sustained the decision.
Mr. George Bancroft, the historian, stepped up, and quite surprised
me by expressing to the judge in quite vigorous language his strong
dissent from the decision.  He soon afterward published a pamphlet
reviewing it adversely.  I supposed that what Mr. Bancroft might do
with a decision of the Supreme Court of the United States, a humbler
individual might be allowed to do with the decision of a local New
York judge.

The defense appealed the case to a higher court of three judges,
where the finding of the lower court was sustained by a majority
of two to one.  It was then carried to the Court of Appeals, the
highest in the State.  Here the decision was set aside on what
seemed to me the common sense ground that the court had ignored
the rights of the defendant in the case, who certainly had some,
and it must therefore be remanded for a new trial.

Meantime Peters had died; and it is painful to think that his death
may have been accelerated by the annoyances growing out of the suit.
One morning, in the summer of 1890, he was found dead on the steps of
his little dwelling, having apparently fallen in a fit of apoplexy
or heart failure as he was on his way to the observatory the night
before.  His heirs had no possible object in pushing the suit;
probably his entire little fortune was absorbed in the attendant
expenses.

When the difference with Borst was first heard of it was, I think,
proposed to Peters by several of his friends, including myself, that
the matter should be submitted to an arbitration of astronomers.
But he would listen to nothing of the sort.  He was determined to
enforce his legal rights by legal measures.  A court of law was,
in such a case, at an enormous disadvantage, as compared with
an astronomical board of arbitration.  To the latter all the
circumstances would have been familiar and simple, while the
voluminous evidence, elucidated as it was by the arguments of
counsel on the two sides, failed to completely enlighten the court
on the points at issue.  One circumstance will illustrate this.
Some allusion was made during the trial to Peters's work while he was
abroad, in investigating the various manuscripts of the Almagest of
Ptolemy and preparing a commentary and revised edition of Ptolemy's
Catalogue of Stars.  This would have been an extremely important and
original work, most valuable in the history of ancient astronomy.
But the judge got it mixed up in his mind with the work before the
court, and actually supposed that Peters spent his time in Europe
in searching ancient manuscripts to get material for the catalogue
in question.  He also attributed great importance to the conception of
the catalogue, forgetting that, to use the simile of a writer in the
"New York Evening Post," such a conception was of no more value than
the conception of a railroad from one town to another by a man who
had no capital to build it.  No original investigation was required
on one side or the other.  It was simply a huge piece of work done
by a young man with help from his sisters, suggested by Peters,
and now and then revised by him in its details.  It seemed to me
that the solution offered by Borst was eminently proper, and I was
willing to say so, probably at the expense of Peters's friendship,
on which I set a high value.


I have always regarded the work on Ptolemy's catalogue of stars,
to which allusion has just been made, as the most important Peters
ever undertook.  It comprised a critical examination and comparison
of all the manuscripts of the Almagest in the libraries of Europe,
or elsewhere, whether in Arabic or other languages, with a view
of learning what light might be thrown on the doubtful questions
growing out of Ptolemy's work.  At the Litchfield Observatory I
had an opportunity of examining the work, especially the extended
commentaries on special points, and was so impressed by the learning
shown in the research as to express a desire for its speedy completion
and publication.  In fact, Peters had already made one or more
communications to the National Academy of Sciences on the subject,
which were supposed to be equivalent to presenting the work to the
academy for publication.  But before the academy put in any claim for
the manuscript, Mr. E. B. Knobel of London, a well-known member of
the Royal Astronomical Society, wrote to Peters's executors, stating
that he was a collaborator with Peters in preparing the work, and
as such had a claim to it, and wished to complete it.  He therefore
asked that the papers should be sent to him.  This was done, but
during the twelve years which have since elapsed, nothing more has
been heard of the work.  No one, so far as I know, ever heard of
Peters's making any allusion to Mr. Knobel or any other collaborator.
He seems to have always spoken of the work as exclusively his own.


Among the psychological phenomena I have witnessed, none has appeared
to me more curious than a susceptibility of certain minds to become
imbued with a violent antipathy to the theory of gravitation.
The anti-gravitation crank, as he is commonly called, is a regular
part of the astronomer's experience.  He is, however, only one of a
large and varied class who occupy themselves with what an architect
might consider the drawing up of plans and specifications for a
universe.  This is, no doubt, quite a harmless occupation; but the
queer part of it is the seeming belief of the architects that the
actual universe has been built on their plans, and runs according to
the laws which they prescribe for it.  Ether, atoms, and nebulæ are
the raw material of their trade.  Men of otherwise sound intellect,
even college graduates and lawyers, sometimes engage in this business.
I have often wondered whether any of these men proved that, in all
the common schools of New York, the power which conjugates the verbs
comes, through some invisible conduit in the earth, from the falls
of Niagara.  This would be quite like many of the theories propounded.

Babbage's "Budget of Paradoxes" is a goodly volume descriptive of
efforts of this sort.  It was supplemented a year or two ago by
a most excellent and readable article on eccentric literature, by
Mr. John Fiske, which appeared in the "Atlantic Monthly."  Here the
author discussed the subject so well that I do not feel like saying
much about it, beyond giving a little of my own experience.

Naturally the Smithsonian Institution was, and I presume still is,
the great authority to which these men send their productions.
It was generally a rule of Professor Henry always to notice
these communications and try to convince the correspondents of
their fallacies.  Many of the papers were referred to me; but a
little experience showed that it was absolutely useless to explain
anything to these "paradoxers."  Generally their first communication
was exceedingly modest in style, being evidently designed to lead on
the unwary person to whom it was addressed.  Moved to sympathy with
so well-meaning but erring an inquirer, I would point out wherein
his reasoning was deficient or his facts at fault.  Back would come
a thunderbolt demonstrating my incapacity to deal with the subject
in terms so strong that I could not have another word to say.

The American Association for the Advancement of Science was another
attraction for such men.  About thirty years ago there appeared at
one of its meetings a man from New Jersey who was as much incensed
against the theory of gravitation as if it had been the source of
all human woe.  He got admission to the meetings, as almost any one
can, but the paper he proposed to read was refused by the committee.
He watched his chance, however, and when discussion on some paper was
invited, he got up and began with the words, "It seems to me that
the astronomers of the present day have gravitation on the brain."
This was the beginning of an impassioned oration which went on in an
unbroken torrent until he was put down by a call for the next paper.
But he got his chance at last.  A meeting of Section Q was called;
what this section was the older members will recall and the reader
may be left to guess.  A programme of papers had been prepared,
and on it appeared Mr. Joseph Treat, on Gravitation.  Mr. Treat got
up with great alacrity, and, amid the astonishment and laughter of
all proceeded to read his paper with the utmost seriousness.

I remember a visit from one of these men with great satisfaction,
because, apparently, he was an exception to the rule in being
amenable to reason.  I was sitting in my office one morning when a
modest-looking gentleman opened the door and looked in.

"I would like to see Professor Newcomb."

"Well, here he is."

"You Professor Newcomb?"

"Yes."

"Professor, I have called to tell you that I don't believe in Sir
Isaac Newton's theory of gravitation!"

"Don't believe in gravitation!  Suppose you jump out of that window
and see whether there is any gravitation or not."

"But I don't mean that.  I mean"--

"But that is all there is in the theory of gravitation; if you jump
out of the window you'll fall to the ground."

"I don't mean that.  What I mean is I don't believe in the Newtonian
theory that gravitation goes up to the moon.  It does n't extend
above the air."

"Have you ever been up there to see?"

There was an embarrassing pause, during which the visitor began to
look a little sheepish.

"N-no-o," he at length replied.

"Well, I have n't been there either, and until one of us can get up
there to try the experiment, I don't believe we shall ever agree on
the subject."

He took his leave without another word.

The idea that the facts of nature are to be brought out by
observation is one which is singularly foreign not only to people
of this class, but even to many sensible men.  When the great comet
of 1882 was discovered in the neighborhood of the sun, the fact was
telegraphed that it might be seen with the naked eye, even in the
sun's neighborhood.  A news reporter came to my office with this
statement, and wanted to know if it was really true that a comet
could be seen with the naked eye right alongside the sun.

"I don't know," I replied; "suppose you go out and look for yourself;
that is the best way to settle the question."

The idea seemed to him to be equally amusing and strange, and on
the basis of that and a few other insipid remarks, he got up an
interview for the "National Republican" of about a column in length.

I think there still exists somewhere in the Northwest a communistic
society presided over by a genius whose official name is Koresh,
and of which the religious creed has quite a scientific turn.
Its fundamental doctrine is that the surface of the earth on which
we live is the inside of a hollow sphere, and therefore concave,
instead of convex, as generally supposed.  The oddest feature of
the doctrine is that Koresh professes to have proved it by a method
which, so far as the geometry of it goes, is more rigorous than any
other that science has ever applied.  The usual argument by which we
prove to our children the earth's rotundity is not purely geometric.
When, standing on the seashore, we see the sails of a ship on
the sea horizon, her hull being hidden because it is below, the
inference that this is due to the convexity of the surface is based
on the idea that light moves in a straight line.  If a ray of light
is curved toward the surface, we should have the same appearance,
although the earth might be perfectly flat.  So the Koresh people
professed to have determined the figure of the earth's surface by
the purely geometric method of taking long, broad planks, perfectly
squared at the two ends, and using them as a geodicist uses his base
apparatus.  They were mounted on wooden supports and placed end to
end, so as to join perfectly.  Then, geometrically, the two would
be in a straight line.  Then the first plank was picked up, carried
forward, and its end so placed against that of the second as to fit
perfectly; thus the continuation of a straight line was assured.
So the operation was repeated by continually alternating the planks.
Recognizing the fact that the ends might not be perfectly square,
the planks were turned upside down in alternate settings, so that
any defect of this sort would be neutralized.  The result was that,
after they had measured along a mile or two, the plank was found to
be gradually approaching the sea sand until it touched the ground.

This quasi-geometric proof was to the mind of Koresh positive.
A horizontal straight line continued does not leave the earth's
surface, but gradually approaches it.  It does not seem that the
measurers were psychologists enough to guard against the effect of
preconceived notions in the process of applying their method.

It is rather odd that pure geometry has its full share of paradoxers.
Runkle's "Mathematical Monthly" received a very fine octavo volume,
the printing of which must have been expensive, by Mr. James Smith,
a respectable merchant of Liverpool.  This gentleman maintained that
the circumference of a circle was exactly 3 1/5 times its diameter.
He had pestered the British Association with his theory, and come
into collision with an eminent mathematician whose name he did
not give, but who was very likely Professor DeMorgan.  The latter
undertook the desperate task of explaining to Mr. Smith his error,
but the other evaded him at every point, much as a supple lad might
avoid the blows of a prize-fighter.  As in many cases of this kind,
the reasoning was enveloped in a mass of verbiage which it was very
difficult to strip off so as to see the real framework of the logic.
When this was done, the syllogism would be found to take this very
simple form:--

The ratio of the circumference to the diameter is the same in all
circles.  Now, take a diameter of 1 and draw round it a circumference
of 3 1/5.  In that circle the ratio is 3 1/5; therefore, by the
major premise, that is the ratio for all circles.

The three famous problems of antiquity, the duplication of the cube,
the quadrature of the circle, and the trisection of the angle, have
all been proved by modern mathematics to be insoluble by the rule
and compass, which are the instruments assumed in the postulates
of Euclid.  Yet the problem of the trisection is frequently attacked
by men of some mathematical education.  I think it was about 1870
that I received from Professor Henry a communication coming from
some institution of learning in Louisiana or Texas.  The writer
was sure he had solved the problem, and asked that it might receive
the prize supposed to be awarded by governments for the solution.
The construction was very complicated, and I went over the whole
demonstration without being able at first to detect any error.
So it was necessary to examine it yet more completely and take it
up point by point.  At length I found the fallacy to be that three
lines which, as drawn, intersected in what was to the eye the same
point on the paper, were assumed to intersect mathematically in
one and the same point.  Except for the complexity of the work,
the supposed construction would have been worthy of preservation.

Some years later I received, from a teacher, I think, a supposed
construction, with the statement that he had gone over it very
carefully and could find no error.  He therefore requested me to
examine it and see whether there was anything wrong.  I told him in
reply that his work showed that he was quite capable of appreciating
a geometric demonstration; that there was surely something wrong in
it, because the problem was known to be insoluble, and I would like
him to try again to see if he could not find his error.  As I never
again heard from him, I suppose he succeeded.

One of the most curious of these cases was that of a student, I am not
sure but a graduate, of the University of Virginia, who claimed that
geometers were in error in assuming that a line had no thickness.
He published a school geometry based on his views, which received
the endorsement of a well-known New York school official and, on
the basis of this, was actually endorsed, or came very near being
endorsed, as a text-book in the public schools of New York.

From my correspondence, I judge that every civilized country has
its share of these paradoxers.  I am almost constantly in receipt
of letters not only from America, but from Europe and Asia, setting
forth their views.  The following are a few of these productions
which arrived in the course of a single season.

 _Dear Sir_,--Though a stranger to you, Sir, I take the liberty
 to enlist your interest in a Cause,--so grand, so beautiful,
 as to eclipse anything ever presented to the highest tribunal
 of human intellect and intuition.

 Trusting you to be of liberal mind, Sir, I have mailed you
 specimen copy of the "Banner of Light," which will prove
 somewhat explanatory of my previous remarks.

 Being a student of Nature and her wonderful laws, as they
 operate in that subtle realm of human life,--the soul,
 for some years, I feel well prepared to answer inquiries
 pertaining to this almost unknown field of scientific
 research, and would do so with much pleasure, as I am
 desirous to contribute my mite to the enlightenment of
 mankind upon this most important of all subjects.

   Yours very truly,  ------ ------

   Mexico, 16 Oct. 1897.

 Dear Sir,--I beg to inform you that I have forwarded by to
 days mail to your adress a copy of my 20th Century planetary
 spectacle with a clipping of a german newspaper here.
 Thirty hours for 3000 years is to day better accepted than
 it was 6 years ago when I wrote it, although it called even
 then for some newspaper comment, especially after President
 Cleveland's election, whose likeness has been recognized on
 the back cover, so has been my comet, which was duly anounced
 by an Italian astronomer 48 hours before said election.
 A hint of Jupiters fifth satelite and Mars satelites is
 also to be found in my planetary spectacle but the most
 striking feature of such a profetic play is undoubtedly
 the Allegory of the Paris fire my entire Mercury scene and
 next to it is the Mars scene with the wholesale retreat of
 the greecs that is just now puzzling some advanced minds.
 Of cours the musical satelites represent at the same time the
 european concert with the disgusted halfuroons face in one
 corner and Egypt next to it and there can be no doubt that
 the world is now about getting ready to applaud such a grand
 realistic play on the stage after even the school children
 of Chicago adopted a great part of my moral scuol-club
 (act II) as I see from the Times Herald Oct. 3d. and they
 did certainly better than the Mars Fools did in N. Y. 4
 years ago with that Dire play, A trip to Mars.  The only
 question now is to find an enterprising scientist to not
 only recomend my play but put some 1500$ up for to stage
 it at once perhaps you would be able to do so.

 Mr. Newcombe:

 _Dear Sir_,--I forwarded you photographs of several
 designs which demonstrate by illustrations in physics,
 metaphysics, phrenology, mechanics, Theology, Law magnetism
 Astronomy etc--the only true form and principles of universal
 government, and the greatest life sustaining forces in this
 universe, I would like to explain to you and to some of the
 expert government detectives every thing in connection with
 those illustrations since 1881; I have traveled over this
 continent; for many years I have been persecuted. my object
 in sending you those illustrations is to see if you could
 influence some Journalist in this City, or in Washington to
 illustrate and write up the interpretation of those designs,
 and present them to the public through the press.

 You know that very few men can grasp or comprehend in what
 relation a plumb line stands to the sciences, or to the
 nations of this earth, at the present time, by giving the
 correct interpretation of Christian, Hebrew, & Mohammedian
 prophesy, this work presents a system of international law
 which is destined to create harmony peace and prosperity.

One day in July, 1895, I was perplexed by the receipt of a cable
dispatch from Paris in the following terms:--

 Will you act?  Consult Gould.  Furber.

The dispatch was accompanied by the statement that an immediate answer
was requested and prepaid.  Dr. Gould being in Cambridge, and I in
Washington, it was not possible to consult him immediately as to what
was meant.  After consultation with an official of the Coast Survey,
I reached the conclusion that the request had something to do with
the International Metric Commission, of which Dr. Gould was a member,
and that I was desired to act on some committee.  As there could be no
doubt of my willingness to do this, I returned an affirmative answer,
and wrote to Dr. Gould to know exactly what was required.  Great was
my surprise to receive an answer stating that he knew nothing of
the subject, and could not imagine what was meant.  The mystery
was dispelled a few days later by a visit from Dr. E. R. L. Gould,
the well-known professor of economics, who soon after extended his
activities into the more practical line of the presidency of the
Suburban Homes and Improvement Company of New York.  He had just
arrived from Paris, where a movement was on foot to induce the French
government to make such modifications in the regulations governing
the instruction and the degrees at the French universities as would
make them more attractive to American students, who had hitherto
frequented the German universities to the almost entire exclusion
of those of France.  It was desired by the movers in the affair to
organize an American committee to act with one already formed at
Paris; and it was desired that I should undertake this work.

I at first demurred on two grounds.  I could not see how, with
propriety, Americans could appear as petitioners to the French
government to modify its educational system for their benefit.
Moreover, I did not want to take any position which would involve me
in an effort to draw American students from the German universities.

He replied that neither objection could be urged in the case.
The American committee would act only as an adviser to the French
committee, and its sole purpose was to make known to the latter
what arrangements as regarded studies, examinations, and degrees
would be best adapted to meet the views and satisfy the needs of
American students.  There was, moreover, no desire to draw American
students from the German universities; it was only desired to give
them greater facilities in Paris.

The case was fortified by a letter from M. Michel Bréal, member of
the Institute of France, and head of the Franco-American committee,
as it was called in Paris, expressing a very flattering desire that
I should act.

I soon gave my consent, and wrote to the presidents of eight or
ten of our leading universities and several Washington officials
interested in education, to secure their adhesion.  With a single
exception, the responses were unanimous in the affirmative, and
I think the exception was due to a misapprehension of the objects
of the movement.  The views of all the adhering Americans were then
requested, and a formal meeting was held, at which they were put into
shape.  It is quite foreign to my present object to go into details,
as everything of interest in connection with the matter will be
found in educational journals.  One point may, however, be mentioned.
The French committee was assured that whatever system of instruction
and of degrees was offered, it must be one in which no distinction
was made between French and foreigners.  American students would
not strive for a degree which was especially arranged for them alone.

I soon found that the movement was a much more complex one than it
appeared at first sight, and that all the parties interested in Paris
did not belong to one and the same committee.  Not long after we had
put our suggestions into shape, I was gratified by a visit from Dom
de la Tremblay, prior of the Benedictine Convent of Santa Maria, in
Paris, a most philanthropic and attractive gentleman, who desired to
promote the object by establishing a home for the American students
when they should come.  Knowing the temptations to which visiting
youth would be exposed, he was desirous of founding an establishment
where they could live in the best and most attractive surroundings.
He confidently hoped to receive the active support of men of wealth
in this country in carrying out his object.

It was a somewhat difficult and delicate matter to explain to the
philanthropic gentleman that American students were not likely to
collect in a home specially provided for them, but would prefer
to find their own home in their own way.  I tried to do it with
as little throwing of cold water as was possible, but, I fear,
succeeded only gradually.  But after two or three visits to New York
and Washington, it became evident to him that the funds necessary
for his plan could not be raised.

The inception of the affair was still not clear to me.  I learned
it in Paris the year following.  Then I found that the movement
was started by Mr. Furber, the sender of the telegram, a citizen of
Chicago, who had scarcely attained the prime of life, but was gifted
with that indomitable spirit of enterprise which characterizes
the metropolis of the West.  What he saw of the educational
institutions of Paris imbued him with a high sense of their value,
and he was desirous that his fellow-countrymen should share in the
advantages which they offered.  To induce them to do this, it was only
necessary that some changes should be made in the degrees and in the
examinations, the latter being too numerous and the degrees bearing no
resemblance to those of Germany and the United States.  He therefore
addressed a memorial to the Minister of Public Instruction, who was
much impressed by the view of the case presented to him, and actively
favored the formation of a Franco-American committee to carry out
the object.  Everything was gotten ready for action, and it only
remained that the prime mover should submit evidence that educators in
America desired the proposed change, and make known what was wanted.

Why I should have been selected to do this I do not know, but suppose
it may have been because I had just been elected a foreign associate
of the Institute, and was free from trammels which might have hindered
the action of men who held official positions in the government or
at the heads of universities.  The final outcome of the affair was
the establishment in the universities of France of the degree of
Doctor of the University, which might be given either in letters
or in science, and which was expected to correspond as nearly as
possible to the degree of Doctor of Philosophy in Germany and America.

One feature of the case was brought out which may be worthy of
attention from educators.  In a general way it may be said that our
Bachelor's degree does not correspond to any well-defined stage of
education, implying, as it does, something more than that foundation
of a general liberal education which the degree implies in Europe, and
not quite so much as the Doctor's degree.  I found it very difficult,
if not impossible, to make our French friends understand that our
American Bachelor's degree was something materially higher than the
Baccalaureate of the French Lycée, which is conferred at the end of
a course midway between our high school and our college.


From education at the Sorbonne I pass to the other extreme.
During a stay in Harper's Ferry in the autumn of 1887, I had an
object lesson in the state of primary education in the mountain
regions of the South.  Accompanied by a lady friend, who, like
myself, was fond of climbing the hills, I walked over the Loudon
heights into a sequestered valley, out of direct communication with
the great world.  After visiting one or two of the farmhouses, we
came across a school by the roadside.  It was the hour of recess,
and the teacher was taking an active part in promoting the games
in which the children were engaged.  It was suggested by one of us
that it would be of interest to see the methods of this school; so
we approached the teacher on the subject, who very kindly offered
to call his pupils together and show us his teaching.

First, however, we began to question him as to the subjects of
instruction.  The curriculum seemed rather meagre, as he went over it.
I do not think it went beyond the three R's.

"But do you not teach grammar as well as reading?" I asked.

"No, I am sorry to say, I do not.  I did want to teach grammar,
but the people all said that they had not been taught grammar, and
had got along very well without it, and did not see why the time of
the children should be taken up by it."

"If you do not teach grammar from the book, you could at least teach
it by practice in composition.  Do you not exercise them in writing
compositions?"

"I did try that once, and let me tell you how it turned out.  They got
up a story that I was teaching the children to write love letters,
and made such a clamor about it that I had to stop."

He then kindly offered to show us what he did teach.  The school was
called together and words to spell were given out from a dictionary.
They had got as far as "patrimony," and went on from that word to a
dozen or so that followed it.  The words were spelled by the children
in turn, but nothing was said about the definition or meaning of
the word.  He did not explain whether, in the opinion of the parents,
it was feared that disastrous events might follow if the children
knew what a "patrimony" was, but it seems that no objections were
raised to their knowing how to spell it.

We thanked him and took our leave, feeling that we were well repaid
for our visit, however it might have been with the teacher and
his school.


I have never been able to confine my attention to astronomy with
that exclusiveness which is commonly considered necessary to the
highest success in any profession.  The lawyer finds almost every
branch of human knowledge to be not only of interest, but of actual
professional value, but one can hardly imagine why an astronomer
should concern himself with things mundane, and especially with
sociological subjects.  But there is very high precedent for such
a practice.  Quite recently the fact has been brought to light that
the great founder of modern astronomy once prepared for the government
of his native land a very remarkable paper on the habit of debasing
the currency, which was so prevalent during the Middle Ages. [1]  The
paper of Copernicus is, I believe, one of the strongest expositions
of the evil of a debased currency that had ever appeared.  Its tenor
may be judged by the opening sentence, of which the following is a
free translation:--

 Innumerable though the evils are with which kingdoms,
 principalities, and republics are troubled, there are four
 which in my opinion outweigh all others,--war, death, famine,
 and debasement of money.  The three first are so evident that
 no one denies them, but it is not thus with the fourth.

A certain interest in political economy dates with me from the age of
nineteen, when I read Say's work on the subject, which was at that
time in very wide circulation.  The question of protection and free
trade was then, as always, an attractive one.  I inclined towards
the free trade view, but still felt that there might be another
side to the question which I found myself unable fully to grasp.
I remember thinking it quite possible that Smith's "Wealth of Nations"
might be supplemented by a similar work on the strength of nations,
in which not merely wealth, but everything that conduces to national
power should be considered, and that the result of the inquiry
might lead to practical conclusions different from those of Smith.
Very able writers, among them Henry C. Carey, had espoused the side
of protection, but for some years I had not time to read their works,
and therefore reserved my judgment until more light should appear.

Thus the matter stood until an accident impelled me to look into
the subject.  About 1862 or 1863 President Thomas Hill, of Harvard
University, paid a visit to Washington.  I held him in very high
esteem.  He was a mathematician, and had been the favorite student of
Professor Benjamin Peirce; but I did not know that he had interested
himself in political economy until, on the occasion in question, I
passed an evening with him at the house where he was a guest.  Here he
told me that in a public lecture at Philadelphia, a few evenings
before, he had informed his hearers that they had amongst them one
of the greatest philosophers of the time, Henry C. Carey.  He spoke
of his works in such enthusiastic terms, describing especially his
law of the tendency of mankind to be attracted towards the great
capitals or other centres of population, that I lost no time in
carefully reading Carey's "Principles of Social Science."

The result was much like a slap in the face.  With every possible
predisposition to look favorably on its teachings, I was unable to
find anything in them but the prejudiced judgments of a one-sided
thinker, fond of brilliant general propositions which really had
nothing serious to rest upon either in fact or reason.  The following
parody on his method occurred to me:--

The physicians say that quinine tends to cure intermittent fever.
If this be the case, then where people use most quinine, they
will have least intermittent fever.  But the facts are exactly
the opposite.  Along the borders of the lower Mississippi, where
people take most quinine, they suffer most from fever; therefore
the effect of quinine is the opposite of that alleged.

I earnestly wished for an opportunity to discuss the matter further
with Mr. Hill, but it was never offered.

During the early years of the civil war, when the country was flooded
with an irredeemable currency, I was so much disturbed by what
seemed to me the unwisdom of our financial policy, that I positively
envied the people who thought it all right, and therefore were free
from mental perturbation on the subject.  I at length felt that I
could keep silent no longer, and as the civil war was closing, I
devoted much time to writing a little book, "Critical Examination
of Our Financial Policy during the Southern Rebellion."  I got
this published by the Appletons, but had to pay for the production.
It never yielded enough to pay the cost of printing, as is very apt
to be the case with such a hook when it is on the unpopular side
and by an unknown author.  It had, however, the pleasant result of
bringing me into friendly relations with two of the most eminent
financiers of the country, Mr. Hugh McCulloch and Mr. George S. Coe,
the latter president of one of the principal banks of New York.
The compliments which these men paid to the book were the only
compensation I got for the time and money expended upon it.


In 1876 the "North American Review" published a centennial number
devoted to articles upon our national progress during the first
century of our existence.  I contributed the discussion of our
work in exact science.  Natural science had been cultivated among
us with great success, but I was obliged to point out our backward
condition in every branch of exact science, which was more marked
the more mathematical the character of the scientific work.  In pure
mathematics we seemed hopelessly behind in the race.

I suppose that every writer who discusses a subject with a view
of influencing the thought of the public, must be more or less
discouraged by the small amount of attention the best he can say is
likely to receive from his fellow-men.  No matter what his own opinion
of the importance of the matters he discusses, and the results that
might grow out of them if men would only give them due attention,
they are lost in the cataract of utterances poured forth from the
daily, weekly, and monthly press.  I was therefore much pleased,
soon after the article appeared, to be honored with a visit from
President Gilman, who had been impressed with my views, and wished
to discuss the practicability of the Johns Hopkins University, which
was now being organized, doing something to promote the higher forms
of investigation among us.

One of the most remarkable mathematicians of the age, Professor
J. J. Sylvester, had recently severed his connection with the Royal
Military Academy at Woolich, and it had been decided to invite him
to the chair of mathematics at the new university.  It was considered
desirable to have men of similar world-wide eminence in charge of the
other departments in science.  But this was found to be impracticable,
and the policy adopted was to find young men whose reputation was
yet to be made, and who would be the leading men of the future,
instead of belonging to the past.

All my experience would lead me to say that the selection of the
coming man in science is almost as difficult as the selection of
youth who are to become senators of the United States.  The success
of the university in finding the young men it wanted, has been one
of the most remarkable features in the history of the Johns Hopkins
University.  Of this the lamented Rowland affords the most striking,
but by no means the only instance.  Few could have anticipated
that the modest and scarcely known youth selected for the chair of
physics would not only become the leading man of his profession in
our country, but one of the chief promoters of scientific research
among us.  Mathematical study and research of the highest order
now commenced, not only at Baltimore, but at Harvard, Columbia,
and other centres of learning, until, to-day, we are scarcely behind
any nation in our contributions to the subject.


The development of economic study in our country during the last
quarter of the last century is hardly less remarkable than that of
mathematical science.  A great impulse in this direction was given
by Professor R. T. Ely, who, when the Johns Hopkins University was
organized, became its leading teacher in economics.  He had recently
come from Germany, where he had imbibed what was supposed to be
a new gospel in economics, and he now appeared as the evangelist
of what was termed the historical school.  My own studies were of
course too far removed from this school to be a factor in it.  But,
so far as I was able, I fought the idea of there being two schools,
or of any necessary antagonism between the results of the two methods.
It was true that there was a marked difference in form between them.
Some men preferred to reach conclusions by careful analysis of human
nature and study of the acts to which men were led in seeking to
carry out their own ends.  This was called the old-school method.
Others preferred to study the problem on a large scale, especially
as shown in the economic development of the country.  But there
could be no necessary difference between the conclusions thus reached.

One curious fact, which has always been overlooked in the history
of economics in our country, shows how purely partisan was the idea
of a separation of the two schools.  The fact is that the founder of
the historic school among us, the man who first introduced the idea,
was not Ely, but David A. Wells.  Up to the outbreak of the civil
war, Mr. Wells had been a writer on scientific subjects without any
special known leaning toward economies; but after it broke out he
published a most noteworthy pamphlet, setting forth the resources of
our country for carrying on war and paying a debt, in terms so strong
as to command more attention than any similar utterance at the time.
This led to his appointment as Special Commissioner of Revenue,
with the duty of collecting information devising the best methods of
raising revenue.  His studies in this line were very exhaustive, and
were carried on by the methods of the historic school of economics.
I was almost annoyed to find that, if any economic question was
presented to him, he rushed off to the experience of some particular
people or nation--it might be Sweden or Australia--instead of going
down to fundamental principles.  But I could never get him interested
in this kind of analysis.

One of Professor Ely's early movements resulted in the organization of
the American Economic Association.  His original plan was that this
society should have something like a creed to which its members were
expected to subscribe.  A discussion of the whole subject appeared
in the pages of "Science," a number of the leading economists of
the country being contributors to it.  The outcome of the whole
matter has been a triumph for what most men will now consider reason
and good sense.  The Economic Association was scarcely more than
organized when it broke loose from all creeds and admitted into
its ranks investigators of the subject belonging to every class.
I think the last discussion on the question of two schools occurred
at the New York meeting, about 1895, after which the whole matter
was dropped and the association worked together as a unit.

As Professor Ely is still a leader on the stage, I desire to do him
justice in one point.  I am able to do so because of what I have
always regarded as one of the best features of the Johns Hopkins
University--the unity of action which pervaded its work.  There is
a tendency in such institutions to be divided up into departments,
not only independent of each other, but with little mutual help
or sympathy.  Of course every department has the best wishes of
every other, and its coöperation when necessary, but the tendency
is to have nothing more than this.  In 1884, after the resignation
of Professor Sylvester, I was invited by President Gilman to act as
head of the department of mathematics.  I could not figure as the
successor of Sylvester, and therefore suggested that my title should
be professor of mathematics and astronomy.  The examinations of
students for the degree of Doctor of Philosophy were then, as now,
all conducted by a single "Board of University Studies," in which
all had equal powers, although of course no member of the board took
an active part in cases which lay entirely outside of his field.
But the general idea was that of mutual coöperation and criticism
all through.  Each professor was a factor in the department of
another in a helpful and not an antagonistic way, and all held
counsel on subjects where the knowledge of all was helpful to each.
I cannot but think that the wonderful success of the Johns Hopkins
University is largely due to this feature of its activity, which
tended to broaden both professors and students alike.

In pursuance of this system I for several years took part in the
examinations of students of economics for their degrees.  I found that
Professor Ely's men were always well grounded in those principles
of economic theory which seemed to me essential to a comprehension
of the subject on its scientific side.

Being sometimes looked upon as an economist, I deem it not improper
to disclaim any part in the economic research of to-day.  What I have
done has been prompted by the conviction that the greatest social want
of the age is the introduction of sound thinking on economic subjects
among the masses, not only of our own, but of every other country.
This kind of thinking I have tried to promote in our own country
by such books as "A Plain Man's Talk on the Labor Question," and
"Principles of Political Economy."


My talks with Professor Henry used to cover a wide field in scientific
philosophy.  Adherence to the Presbyterian church did not prevent his
being as uncompromising an upholder of modern scientific views of the
universe as I ever knew.  He was especially severe on the delusions
of spiritualism.  To a friend who once told him that he had seen a
"medium" waft himself through a window, he replied, "Judge, you never
saw that; and if you think you did, you are in a dangerous mental
condition and need the utmost care of your family and your physician."

Among the experiences which I heard him relate more than once,
I think, was one with a noted medium.  Henry was quite intimate
with President Lincoln, who, though not a believer in spiritualism,
was from time to time deeply impressed by the extraordinary feats
of spiritualistic performers, and naturally looked to Professor
Henry for his views and advice on the subject.  Quite early in his
administration one of these men showed his wonderful powers to the
President, who asked him to show Professor Henry his feats.

Although the latter generally avoided all contact with such men,
he consented to receive him at the Smithsonian Institution.
Among the acts proposed was that of making sounds in various
quarters of the room.  This was something which the keen senses
and ready experimental faculty of the professor were well qualified
to investigate.  He turned his head in various positions while the
sounds were being emitted.  He then turned toward the man with the
utmost firmness and said, "I do not know how you make the sounds,
but this I perceive very clearly: they do not come from the room but
from your person."  It was in vain that the operator protested that
they did not, and that he had no knowledge how they were produced.
The keen ear of his examiner could not be deceived.

Sometime afterward the professor was traveling in the east, and
took a seat in a railway car beside a young man who, finding who
his companion was, entered into conversation with him, and informed
him that he was a maker of telegraph and electrical instruments.
His advances were received in so friendly a manner that he went
further yet, and confided to Henry that his ingenuity had been called
into requisition by spiritual mediums, to whom he furnished the
apparatus necessary for the manifestations.  Henry asked him by what
mediums he had been engaged, and was surprised to find that among
them was the very man he had met at the Smithsonian.  The sounds
which the medium had emitted were then described to the young man,
who in reply explained the structure of the apparatus by which they
were produced, which apparatus had been constructed by himself.
It was fastened around the muscular part of the upper arm, and was
so arranged that clicks would be produced by a simple contraction
of the muscle, unaccompanied by any motion of the joints of the arm,
and entirely invisible to a bystander.

During the Philadelphia meeting of the American Association for the
Advancement of Science, held in 1884, a few members were invited by
one of the foreign visitors, Professor Fitzgerald of Dublin, I think,
to a conference on the subject of psychical research.  The English
society on this subject had been organized a few years before, and the
question now was whether there was interest enough among us to lead
to the organization of an American Society for Psychical Research.
This was decided in the affirmative; the society was soon after
formed, with headquarters in Boston, and I was elected its first
president, a choice which Powell, of Washington, declared to be
ridiculous in the highest degree.

On accepting this position, my first duty was to make a careful study
of the publications of the parent society in England, with a view
of learning their discoveries.  The result was far from hopeful.
I found that the phenomena brought out lacked that coherence
and definiteness which is characteristic of scientific truths.
Remarkable effects had been witnessed; but it was impossible to say,
Do so and so, and you will get such an effect.  The best that could
be said was, perhaps you will get an effect, but more likely you
will not.  I could not feel any assurance that the society, with
all its diligence, had done more than add to the mass of mistakes,
misapprehensions of fact, exaggerations, illusions, tricks, and
coincidences, of which human experience is full.  In the course of a
year or two I delivered a presidential address, in which I pointed
out the difficulties of the case and the inconclusiveness of the
supposed facts gathered.  I suggested further experimentation, and
called upon the English society to learn, by trials, whether the
mental influences which they had observed to pass from mind to mind
under specially arranged conditions, would still pass when a curtain
or a door separated the parties.  Fifteen years have since elapsed,
and neither they nor any one else has settled this most elementary
of all the questions involved.  The only conclusion seems to be that
only in exceptional cases does any effect pass at all; and when it
does, it is just as likely to be felt halfway round the world as
behind a curtain in the same room.

Shortly after the conference in Philadelphia I had a long wished-for
opportunity to witness and investigate what, from the descriptions,
was a wonder as great as anything recorded in the history of psychic
research or spiritualism.  Early in 1885 a tall and well-built young
woman named Lulu Hurst, also known as the "Georgia magnetic girl,"
gave exhibitions in the eastern cities which equaled or exceeded the
greatest feats of the Spiritualists.  On her arrival in Washington
invitations were sent to a number of our prominent scientific men to
witness a private exhibition which she gave in advance of her public
appearance.  I was not present, but some who attended were so struck
by her performance that they arranged to have another exhibition
in Dr. Graham Bell's laboratory.  I can give the best idea of the
case if I begin with an account of the performance as given by the
eye-witnesses at the first trial.  We must remember that this was not
the account of mere wonder-seekers, but of trained scientific men.
Their account was in substance this:--

A light rod was firmly held in the hands of the tallest and most
muscular of the spectators.  Miss Lulu had only to touch the
rod with her fingers when it would begin to go through the most
extraordinary manoeuvres.  It jerked the holder around the room with
a power he was unable to resist, and finally threw him down into a
corner completely discomfited.  Another spectator was then asked to
take hold of the rod, and Miss Lulu extended her arms and touched
each end with the tip of her finger.  Immediately the rod began to
whirl around on its central axis with such force that the skin was
nearly taken off the holder's hands in his efforts to stop it.

A heavy man being seated in a chair, man and chair were lifted
up by the fair performer placing her hands against the sides.
To substantiate the claim that she herself exerted no force, chair and
man were lifted without her touching the chair at all.  The sitter
was asked to put his hands under the chair; the performer put her
hands around and under his in such a way that it was impossible
for her to exert any force on the chair except through his hands.
The chair at once lifted him up without her exerting any pressure
other than the touch upon his hands.

Several men were then invited to hold the chair still.  The performer
then began to deftly touch it with her finger, when the chair again
began to jump about in spite of the efforts of three or four men to
hold it down.

A straw hat being laid upon a table crown downwards, she laid her
extended hands over it.  It was lifted up by what seemed an attractive
force similar to that of a magnet upon an armature, and was in danger
of being torn to pieces in the effort of any one holding it to keep it
down, though she could not possibly have had any hold upon the object.

Among the spectators were physicians, one or more of whom grasped
Miss Lulu's arms while the motions were going on, without finding
any symptoms of strong muscular action.  Her pulse remained normal
throughout.  The objects which she touched seemed endowed with a
force which was wholly new to science.

So much for the story.  Now for the reality.  The party appeared at
the Volta Laboratory, according to arrangement.  Those having the
matter in charge were not professional mystifiers of the public,
and showed no desire to conceal anything.  There was no darkening of
rooms, no putting of hands under tables, no fear that spirits would
refuse to act because of the presence of some skeptic, no trickery
of any sort.

We got up such arrangements as we could for a scientific investigation
of the movements.  One of these was a rolling platform on which
Miss Lulu was requested to stand while the forces were exerted.
Another device was to seat her on a platform scale while the chair
was lifting itself.

These several experiments were tried in the order in which I have
mentioned them.  I took the wonderful staff in my hands, and Miss Lulu
placed the palms of her hands and extended them against the staff near
the ends, while I firmly grasped it with my two hands in the middle.
Of course this gave her a great advantage in the leverage.  I was then
asked to resist the staff with all my force, with the added assurance
from Mrs. Hurst, the mother, that the resistance would be in vain.

Although the performer began with a delicate touch of the staff,
I noticed that she changed the position of her hands every moment,
sometimes seizing the staff with a firm grip, and that it never
moved in any direction unless her hands pressed it in that direction.
As nearly as I could estimate, the force which she exerted might have
been equal to forty pounds, and this exerted first in one way and
then in another was enough to upset the equilibrium of any ordinary
man, especially when the jerks were so sudden and unexpected that
it was impossible for one to brace himself against them.  After a
scene of rather undignified contortion I was finally compelled to
retire in defeat, but without the slightest evidence of any other
force than that exerted by a strong, muscular young woman.  I asked
that the rod might be made to whirl in my hands in the manner which
has been described, but there was clearly some mistake in this whirl,
for Miss Lulu knew nothing on the subject.

Then we proceeded to the chair performance, which was repeated a
number of times.  I noticed that although, at the beginning, the
sitter held his fingers between the chair and the fingers of the
performer, the chair would not move until Miss Lulu had the ball
of her hand firmly in connection with it.  Even then it did not
actually lift the sitter from the ground, but was merely raised up
behind, the front legs resting on the ground, whereupon the sitter
was compelled to get out.  This performance was repeated a number
of times without anything but what was commonplace.

In order to see whether, as claimed, no force was exerted on the
chair, the performer was invited to stand on the platform of the
scales while making the chair move.  The weights had been so adjusted
as to balance a weight of forty pounds above her own.  The result was
that after some general attempts to make the chair move the lever
clicked, showing that a lifting force exceeding forty pounds was
being exerted by the young woman on the platform.  The click seemed
to demoralize the operator, who became unable to continue her efforts.

The experiment of raising a hat turned out equally simple, and the
result of all the trials was only to increase my skepticism as to the
whole doctrine of unknown forces and media of communication between
one mind and another.  I am now likely to remain a skeptic as to
every branch of "occult science" until I find some manifestation of
its reality more conclusive than any I have yet been able to find.

be renamed.

law means that no one owns a United States copyright in these works,
so the Foundation (and you!) can copy and distribute it in the United
States without permission and without paying copyright
royalties. Special rules, set forth in the General Terms of Use part
of this license, apply to copying and distributing Project
Gutenberg™ electronic works to protect the PROJECT GUTENBERG™

the terms of the trademark license, including paying royalties for use
of the Project Gutenberg trademark. If you do not charge anything for

easy. You may use this eBook for nearly any purpose such as creation
of derivative works, reports, performances and research. Project
Gutenberg eBooks may be modified and printed and given away—you may
do practically ANYTHING in the United States with eBooks not protected

    of the country where you are located before using this eBook.
  
1.E.2. If an individual Project Gutenberg™ electronic work is
derived from texts not protected by U.S. copyright law (does not

copyright holder), the work can be copied and distributed to anyone in
the United States without paying any fees or charges. If you are
redistributing or providing access to a work with the phrase “Project

        Gutenberg Literary Archive Foundation at the address specified in

        Literary Archive Foundation.”
    
    • You provide a full refund of any money paid by a user who notifies
        you in writing (or by e-mail) within 30 days of receipt that s/he
        does not agree to the terms of the full Project Gutenberg™
        License. You must require such a user to return or destroy all
        copies of the works possessed in a physical medium and discontinue
        all use of and all access to other copies of Project Gutenberg™
        works.
    
    • You provide, in accordance with paragraph 1.F.3, a full refund of

Section 2. Information about the Mission of Project Gutenberg™

Project Gutenberg™ is synonymous with the free distribution of
electronic works in formats readable by the widest variety of
computers including obsolete, old, middle-aged and new computers. It
exists because of the efforts of hundreds of volunteers and donations
from people in all walks of life.

Volunteers and financial support to provide volunteers with the
assistance they need are critical to reaching Project Gutenberg™’s
goals and ensuring that the Project Gutenberg™ collection will
remain freely available for generations to come. In 2001, the Project
Gutenberg Literary Archive Foundation was created to provide a secure
and permanent future for Project Gutenberg™ and future
generations. To learn more about the Project Gutenberg Literary
Archive Foundation and how your efforts and donations can help, see
Sections 3 and 4 and the Foundation information page at www.gutenberg.org.

Section 4. Information about Donations to the Project Gutenberg
Literary Archive Foundation

Project Gutenberg™ depends upon and cannot survive without widespread
public support and donations to carry out its mission of
increasing the number of public domain and licensed works that can be
freely distributed in machine-readable form accessible by the widest
array of equipment including outdated equipment. Many small donations
($1 to $5,000) are particularly important to maintaining tax exempt
status with the IRS.

The Foundation is committed to complying with the laws regulating
charities and charitable donations in all 50 states of the United
States. Compliance requirements are not uniform and it takes a
considerable effort, much paperwork and many fees to meet and keep up
with these requirements. We do not solicit donations in locations
where we have not received written confirmation of compliance. To SEND
DONATIONS or determine the status of compliance for any particular state
visit www.gutenberg.org/donate.

While we cannot and do not solicit contributions from states where we
have not met the solicitation requirements, we know of no prohibition
against accepting unsolicited donations from donors in such states who
approach us with offers to donate.

International donations are gratefully accepted, but we cannot make
any statements concerning tax treatment of donations received from
outside the United States. U.S. laws alone swamp our small staff.

Please check the Project Gutenberg web pages for current donation
methods and addresses. Donations are accepted in a number of other
ways including checks, online payments and credit card donations. To
donate, please visit: www.gutenberg.org/donate.

Section 5. General Information About Project Gutenberg™ electronic works

Professor Michael S. Hart was the originator of the Project
Gutenberg™ concept of a library of electronic works that could be
freely shared with anyone. For forty years, he produced and
distributed Project Gutenberg™ eBooks with only a loose network of
volunteer support.

Project Gutenberg™ eBooks are often created from several printed
editions, all of which are confirmed as not protected by copyright in
the U.S. unless a copyright notice is included. Thus, we do not
necessarily keep eBooks in compliance with any particular paper
edition.

Most people start at our website which has the main PG search
facility: www.gutenberg.org.

This website includes information about Project Gutenberg™,
including how to make donations to the Project Gutenberg Literary
Archive Foundation, how to help produce our new eBooks, and how to
subscribe to our email newsletter to hear about new eBooks.
