                          Passage To Planet X

                            By HENRY HASSE

                They trailed a legend through the void,
               seeking a world of freedom, adventure and
               wealth. They reached their goal, a planet
                beyond all planets, a weird land of the
             Lost--where silent death prepared to strike.

Mark Travers hoisted himself up from the floor. He leaned against the
supply locker, rubbed his aching jaw where the big man's fist had just
landed, and grinned ruefully.

The big spaceman didn't grin. He faced Mark straddle-legged and
snapped, "Who are you?"

"Mark Travers." His smooth gray eyes surveyed the man's bulk. He
thought he could handle him, but filed it for future reference when he
saw the neutro-gun in the other's fist.

"Travers, eh. A blasted stowaway! You come aboard at Marsport?"

"Obviously."

"How?"

"It was easy," Mark shrugged. "Your ship was small, dark, and carried
no insignia. I watched your men loading supplies secretly. Furthermore,
you hadn't filed your destination with Central Bureau. Just the kind of
set-up I wanted."

"You know a lot," the big spaceman's eyes went hard. "Are you a
sneaking I-S-P? Never mind. I'll see for myself!" He came a step
forward, and his gun got playful with the third button on Mark's
plasticoid shirt. Expertly the man's fingers went over him.

"Careful, there, I'm ticklish!"

"So's the release on this trigger, so just stand still."

Mark stood still. The search revealed no papers or identification of
any kind.

"I'm not I-S-P," Mark told him sincerely. "If I were, do you think
you'd ever have lifted gravs from Marsport?"

"Okay, fella. I'm Mal Driscoll. Sorry I had to clip you so hard, but
you never should have pointed that contraption at me when I stepped in
here. So help me, I thought it was some new kind of weapon." His eyes
narrowed. "What is it?"

For a mere second Mark hesitated. He glanced down at the small,
stub-lensed box which he had clung to.

"Why, it's--only a camera. New type, invention of my own."

Driscoll nodded. "Come on, stowaway. We'll go up and see Janus. No skin
off my teeth, if he wants to keep you aboard."

They stepped out of the room and along a corridor, bracing themselves
against the forward thrust of the rocket engines.

"Who's Janus?"

"Our Commander."

"And what if he doesn't want me aboard?" Unobserved, Mark pressed a
hidden stud in the black box. Tiny but powerful coils hummed to life,
quickly ascended the scale to the inaudible. Camera? Mark smiled to
himself and hoped none of the men here knew anything about cameras!

"You know the space-code on that," Driscoll answered his question. "If
it is so desired, stowaways are tossed into space."

Mark racked his brain. "I don't remember that in the Interplanetary
Code!"

Driscoll turned, grinned at him. "Who's talking about Interplanetary
Code? We make our own!"

       *       *       *       *       *

Janus was in a forward cabin poring over charts on a glass-topped
table. Three other men were lounging there. Janus was six-feet-four,
with bulk to match. He had flaming red hair and an outlandish full
beard that made a vivid splash against the drab gray of his insulated
tunic.

He scowled fiercely as the two men entered. Driscoll pushed Mark
forward.

"Found this stowaway in the supply room. Says his name is Mark Travers.
I don't think he's I-S-P, though."

Janus' deep-set gray eyes seemed to bore through Mark, then they
flashed to the black box.

"What's that?"

"New-design projection camera. It--"

"Put it here," Janus indicated the corner of his desk. Mark did so with
some reluctance. This man was no fool!

The other three men had come down off their bunks and stood there
watching. One of them, Mark noticed, was a Martian.

"Now. Why are you here?"

"You seemed to be the sort of men I wanted to join up with."

"I said why?"

Mark wondered if this man would believe him. He didn't think so.
Nevertheless, he'd already made up his story so he drew a long breath
and told it:

"I was with Tri-Planet News Service working out of Chicago. I happened
to uncover a huge spacer contract graft. I got the names of the higher
ups, photostatic copies of incriminating documents--everything. But the
men involved happened to be _too_ high up; my story was squashed before
it ever reached the wires. I would have been, too, permanently, but I
escaped to Mars--"

Janus was laughing at him behind that red beard. Mark was sure of it.
He shrugged and didn't attempt to go on with the fabrication. It had
been a good try, anyway.

Janus said dryly: "Now tell me the real story. Or shall I tell you?
You received one of the typical BINWI offers. You're running away to
cool off, or maybe to keep your invention out of their hands. Is it
this--ah--camera?" Janus glanced at the compact box lying there.

"That's right," Mark admitted, marvelling at this man. "They made me
several offers but I wouldn't come through. The last one was 'typical',
all right--backed up by some of their hired thugs."

"Why didn't you tell me this in the first place?"

"I wasn't sure how you felt about the BINWI." Mark was still wary.

"The same as you do, although I've never had any contact with them
personally. My special peeve is the Tri-Planet Council, and the BINWI
is a subsidiary. Bureau for the Investigation of New and Worthy
Inventions. A laugh, ain't it?"

Mark didn't think so. "That bureau," he said, "is an octopus preying
on the inventive genius of three planets! Their spies are everywhere,
moving unseen, biding their time. You know the new anti-grav deflectors
the Patrollers are using? A man named Anton Kramer worked that out. He
had it near perfection when he suddenly disappeared. A month later the
deflectors came on the market." Mark's voice was bitter. "There've been
dozens of other cases. The BINWI usually gets what it wants, even if it
means murder."

Janus nodded. "There's a man aboard who'll agree with you on that!
Professor Brownell. Perhaps you shall meet him--later." He turned his
gaze to the four crew members. "All right, men, how about Mark Travers?
Do we accept him as one of us? A vote is in order."

"How do we know he's not a BINWI spy himself?" asked a small man with
piercing black eyes. "He seems to know a lot about 'em!"

"I'm convinced he's not, Ferris. We covered Brownell's trail too well
for that. Let's have the vote."

The "ayes" were unanimous and suddenly these men were friendly,
smiling, as they stepped forward to shake Mark's hand. They were good
handshakes, firm and calloused. Only Ferris' was reluctant.

"There's one thing more," Janus said quietly. "We'll need your picture
for our--shall we say--rogue's gallery? I insist on that. Perhaps I
can take it now--with your camera." He reached to the black box on his
desk, lifted it carelessly up.

       *       *       *       *       *

Mark found himself staring full into the stub-nosed lenses. Sudden
sweat broke on his brow. His gaze lifted and met Janus' gray eyes,
straight and steady upon him.

"Wait!"

"What? Not camera shy, are you?" Janus' fingers seemed to fumble, but
his gaze never left Mark's face.

"The lens isn't set! It--it's special, you know." Mark stepped forward.
His limbs seemed wooden. He took the box from Janus' hands, and
pretending to adjust the lens, his thumb found the hidden stud and
released it. The hum of the inner coils descended the scale again,
became audible for a split second but only to Mark's ears; then they
were dead.

He let out a slow breath, handed the box back. "Okay now. Shoot."

Janus waved it away. "Oh, well, it can wait. We'll get it later." He
came around the desk, thrust out his hand. "Welcome aboard, Travers!
You're one of us."

Mark suddenly knew that Janus knew his secret ... but somehow he wasn't
worried. He wondered if any of the others had noticed the by-play;
moreover, he wondered what being "one of them" meant....

He was soon to know. At that moment a voice sliced through the radio.

"Callisto calling! Earth-Station Six on Callisto! We have had you in
our beam for the past twenty minutes. You are out of bounds and you
display no insignia. As this is a violation of the Space-Code, you will
go into a drift immediately and await the Patrollers who will escort
you to Callisto for investigation! Refusal to obey constitutes outlawry
against the Federation, and the Patrol will act accordingly!"

The men weren't startled. If anything they were amused. The one named
Dethman simply straightened away from the radio and his hard, square
face broke into a grin.

"Think of it, men, we're being outlawed! Now ain't that one for the
books?"

The face of Ral Kaarj, the Martian, was blank and leathery. His
heavy-lidded eyes blinked once or twice, but only his incongruously
high-pitched voice revealed his emotions.

"Tri-Planet Federation!" he shrilled. "Out of bounds! By the red tails
of all the Oogs on Venus, ain't anyone supposed to venture beyond the
asteroids?"

"Not without sanction of those gray-beards in the Council," Janus said,
"and the Earth Corporations who are the real power. You know how they
try to squelch men like us, free-footers who won't play ball with 'em."
He flicked open the communicator to Brownell in the control room. "How
about it, Prof? Get that message?"

"Yes," Mark heard a voice reply. "All right, we'll go into a drift. Let
the Patrollers come, we'll give 'em a show!"

"Right! Need any help?"

"No, but keep the communicator open. And take a look in the V-panel if
you want." Brownell actually seemed pleased!

Janus clicked on the visipanel, turned the magnifying dials. Callisto
was seen in the swimming blackness of space with the huge bulk of
Jupiter as a backdrop. Under Janus' sure fingers the scene expanded,
came nearer.

Minutes passed; then they saw six Patrollers speeding out to meet them.
Brownell had cut rockets and they were in a drift now, waiting.

Waiting for what, Mark wondered. These Patrollers were speedy ships
and deadly, equipped with atomo-bombs, dis-rays and magnetic beams! He
shifted nervously.

The Patrollers came very near. Then they broke formation, arraying
themselves three on each side of the outlaw ship. Magnetic beams, pale
green and swirling, reached out to touch the hull. They fastened there
tenaciously. In this manner they began the route back to Callisto.

Even Janus seemed a little worried now. He turned to the communicator.

"How about it, Professor? Those beams are powerful? Think you can slip
out?"

"Wait and see; I promised a show, didn't I? Tell you what, though,
better break out the acceleration harness!"

       *       *       *       *       *

These were suits within suits, double layers of tough plasticoid. Mark
stepped into his, opened the pressure valve that forced air between the
two thicknesses. The outer one ballooned, giving a grotesque, roly-poly
appearance. He bounced hard against the wall to test it.

"Better open them full," Janus advised.

They were ready. They stood against the far wall and watched the screen
across the room. Callisto was looming. They'd soon be within its
gravity.

Ferris, standing beside Mark, said in a low voice: "What kind of a
news-man are you, Travers? Y'oughta be getting pictures of this. Make
swell release stuff when you get back to Earth." His tone was mocking.

Mark felt a growing dislike of this man. He suppressed a retort, said
curtly instead: "Too late now." He had placed his "camera" safely in
an inside pocket.

The Patrollers' magnetic beams still towed them along at terrific
speed, setting up a slight vibration in the walls.

Suddenly there was a new kind of vibration. Mark didn't know what it
was. Certainly not rocket tubes.

"Get set!" Janus warned.

Someone muttered: "If he slips out of six magnetic beams--" but that
was all. A fierce surge came beneath their feet, and Callisto seemed to
leap at them. Within seconds a ghastly nausea gripped their insides.
The ballooning suits were pressed so flat against the wall it became
impossible to breathe! Their hearts pumped sluggishly, and a gray veil
began to form before their eyes....

These were men so accustomed to hardships that space-acceleration meant
nothing, but now they were experiencing something new in acceleration.
They felt as if their entrails were being compressed into atoms!

Mark could barely see the screen now. The way Callisto was rushing at
them he felt sure the planet was going to blank them out. He tried
to shut his eyes, but even his eyelids wouldn't move! Then Callisto
slipped off the screen, and Mark knew they must have made a sharp
parabola. Two of the Patrollers were glimpsed far behind, reaching out
futilely with dis-rays.

Even as he struggled for breath, Mark wanted to laugh; but the desire
left him suddenly as the tremendous bulk of Jupiter loomed. If they
escaped that gravity--

And they did. They came close, but their parabola tightened, then they
were pulling away. Speed remained constant as Jupiter faded. Mark could
breathe again but he ached through every inch of his body. He could
only think wearily.

This, he thought--this meant they must have accelerated to the sixth,
seventh or even eighth magnitude!


                                  II

Phillias Brownell was a tough little character. He still breathed with
difficulty as Janus unstrapped him from the pneumatic seat, and his
face was ashen; but he hoisted himself up to his full stature of five
feet five and his gray hair bristled. He went to work over the control
console, jabbing hard at gleaming buttons and adjusting the complex
set-up. By now Jupiter was fast fading in the darkness behind them.

"All right," he announced finally, "we're on robot control. We can rest
easy for a while." He sneered in the direction of Jupiter. "We showed
'em some speed, eh? So they want my Frequency Tuner, do they? Let them
come and get it! The dolts, the moronic interfering meddlers!"

Janus plainly showed his relief, as he winked at Mark, who said, "That
was some chance you took. Suppose it hadn't worked?"

"But it did work! That was the final test, and it was necessary. I had
to know how it would react against the beams."

Mark ventured a question. "Frequency Tuner? Is that what gave you the
acceleration? I knew it wasn't rocket power!"

Brownell turned piercing black eyes upon him. "Eh? Janus, who is this?"

Janus vouched for Mark, explained his presence aboard. He added: "The
Bureau's after an invention of his, too. A camera."

The Professor was startled. "Did you say a camera? Since when do they--"

"Ah, but Mark's is a very special camera." Janus smiled maddeningly,
but in the next instant was clapping a friendly hand on Mark's
shoulder. "Don't worry, Travers, your secret's safe with us. We don't
ask questions. You've a right to know our destination, though; come on,
I'll show you."

They repaired to the chart room, where Janus indicated a moving red
line on a glass-encased chart of the solar system. Other lines were
being traced, too, at various angles to their trajectory.

"The red line is our present trajectory. The others are the orbits of
the planets. See, there's Jupiter behind us; notice how close we came."

Mark nodded. Already in his mind's eye he was extending their present
parabola. Distances between these outer planets were vast beyond
imagining! Saturn was just in sight, but at their present speed they
would probably cross its orbit far in advance of the planet. Then came
Uranus, and next Neptune. The space between Neptune and Pluto was
vaster than all.

Mark felt just a little staggered. There was no known record of men
having come this far! Not beyond Jupiter, in fact.

He turned to Janus. "How far do we go?"

"All the way."

"Pluto?"

"Beyond."

Mark thought that over. "There's no planet in our system beyond Pluto!"

"But there is. Planet X. An eccentricity in the orbit of Pluto
indicates there must be a planet beyond. For years astronomers have
known this, but no telescope has been able to pick it out."

Mark grinned weakly. "So that's where we're headed. I guess you know
it'd be awfully easy to overshoot a mark like that!"

"Not with the Frequency Tuner. I understand very little of it, but the
Professor assures me it's a directional finder as well as a power unit."

"Sure, sure. And assuming we locate Planet X and manage to land--what
do you expect to find there?"

       *       *       *       *       *

Janus' eyes were flecked with dancing lights. "What do we hope to find?
George Ketrik! And if you know the man at all, you know that means
adventure and riches."

Ketrik! Mark's mind went back. He began piecing together things he had
heard, fragments and rumors. The man Ketrik and his amazing exploits
had become almost a legend!

"But I have heard," Mark voiced slowly, "that Ketrik died! Plunged into
the sun while trying to negotiate a landing on Vulcan."

"You don't really believe that? Sure, every few years you hear those
stories, but Ketrik always shows up again." Janus sighed. "You know,
I've almost come to believe that he's not human. Where other men
go--men like us--they find that Ketrik has been there first. I've
personally made two fortunes, and lost them, in following his trail!"

Mark was skeptical. "But even he wouldn't dare try for Planet X! He
hasn't the speed that we have. It would take him--"

"Ketrik would dare anything! Why, six months ago I heard that he was
planning this venture; that's why we're here. We five men pooled our
savings to finance Brownell's Frequency Tuner and build this spacer,
in secret, of course. Sure--it would take Ketrik maybe three months to
reach Planet X in some dilapidated little rocket-powered craft. We'll
make it in three days--but I'll wager he's already there!"

"With the whole populace kow-towing at his feet, most likely." It was
Driscoll who spoke as he entered the room, followed by the other men.
"Sure, I'll back the luck of Ketrik every time!"

Dethman shook his head. "Planet X is probably uninhabitable. But I'll
bet my last pair of socks Ketrik's located a cave of diamonds, or
maybe a platinum vein. Toss him in a Venusian sink-hole, he'd come up
wreathed in swamp pearls!"

"He's that sort," Janus agreed. "It was platinum on Mars, cinnabar on
Mercury, plumes on Venus. By the way, I got in on the plumes--made a
fortune. And the other time I saw Ketrik--"

"I recall the time he showed up at the Venusian Prison Swamp," Driscoll
put in. "One day he wasn't there, the next day he was--just like that.
Inside a week he had organized a group of us for a getaway attempt.
Hundreds of others had tried it and failed. Well, he led us safely
across two hundred miles of swamp, supposed to be impassable. Know what
was on the other side? A spaceship, all waiting and ready. He just
wanted to prove it could be done, I guess."

"I only saw him once," Kaarj shrilled eagerly. "That was on Deimos. He
had discovered the secret shrine of the Deimian ancients. He came out
of that shrine decked from head to foot with blazing jewels--but the
Deimians were waiting for him. They're a blood-thirsty tribe, and they
were plenty angry...."

"I never heard this story before," Janus said. "What happened?"

"I stayed a safe distance away in my spaceship, watching and this is
what happened. Ketrik made them a speech! I swear it! He climbed up on
a block of stone in full range of their weapons--and do you know what
his speech consisted of? The entire first chapter of the 'Advanced
Principles of Space Navigation'. He quoted it most violently. Those
Deimians didn't understand a word of it, but I swear to you, when
Ketrik had finished they weren't angry any more! They cheered him! He
walked calmly over to his space-cruiser and blasted away, jewels and
all!"

"I came across him once on Mercury," Dethman contributed. "The
barbarians from the dark side were warring on the race inhabiting the
twilight strip. Well, if it hadn't been for Ketrik, the whole colony
would've been wiped out. They almost made a superman out of him, wanted
him to marry a thousand wives to make sure he'd leave plenty of his
descendants there. And by Jupiter, he almost did! When I left he was
still there, married to ten wives--or was it twelve?"

Mark was enjoying all this. He looked to Ferris, who seemed to be the
only one without a story to tell. Ferris lit a venomous Venusian cigar,
and sneered:

"I don't hold with all this hero-worship, and I don't believe more'n a
tenth of it. Don't think we'll find Ketrik out here either. I've sunk a
year's takin's from my placer on Mars into this venture--"

"And afraid you won't get it back, is that it?" Driscoll snapped. "Why,
that placer you're yapping about was Ketrik's in the first place, and
you know it! Sure, you'd rather hide out some place and manufacture
more Frequency Tuners."

"We'll do that, too, once we make a strike," Janus said thoughtfully.
"We'll equip a whole fleet with 'em, and really exploit the outer
planets. That should give that addle-brained Earth Council something to
really think about!"

       *       *       *       *       *

On the third day they crossed the orbit of Pluto. Mark was in the
control room with Janus and the Professor. The latter pointed to a thin
thread of liquid helium in the directional-finder, surging slightly off
center.

"Pluto's the nearest body now. It must be heavy, to drag us that way."
He gave a touch to the Tuner's impellator, and the helium line came
back to center as their acceleration increased.

The Sun had long since been a pin-point of light. The darkness ahead
was no different from the darkness behind, but the men felt infinitely
more alone. Behind were the known planets. Ahead was X--the unknown. It
might be days more, or merely hours. No one slept now.

It was only hours later when the Finder began acting erratically again.
Brownell, who seemed indefatigable, took over the controls from Janus.
But he didn't try to adjust direction now.

"It's Planet X," he said. "Has to be! We'll let the Finder take us
right there!" He switched on the visipanel and adjusted the lens to
fullest power.

"It must be a dark planet," Mark pointed out. "Certainly the Sun's
light doesn't reach it. How do you hope to see it in the panel?"

"Ordinarily I'd say you were right," Brownell nodded. "But look! There
it is!"

Barely discernible on the screen, they saw a vague pin-point of light.
Brownell glanced at the proximity indicator and gasped.

"Over three million miles--it can't be! Not the way it's pulling us
now. Unless," he added thoughtfully, "it has a gravity grab equal
to that of Jupiter at half the distance! Good Lord!" He tested
instruments, gave experimental side thrusts with the Tuner, but they
came back irresistably into the pull of the planet ahead.

Hour after hour they came nearer. The planet resolved into a dark disc
with a peculiar surrounding halo.

"I don't like it," Janus reflected the thoughts of them all. "That
light--where does it come from? Not the Sun! The Sun doesn't even touch
Pluto!"

"Maybe it has a Sun of its own," ventured Kaarj. "On the other side."

"If it does, the sun moves right along with it in it's orbit!"

"You can tell from here that the planet has no axial rotation,"
Brownell announced. He looked a little worried. "This gravity drag is
getting worse. We're accelerating. Better get into your harness." He
set the example, and the men followed. "I think I can control it with
the Tuner in reverse, but it pays to be safe. You never can tell, out
here; these are strange conditions."

The planet was looming fast. The Professor's hand on the deceleration
lever revealed the strain he was under. Below them now they glimpsed
vast dark plains, and as they came nearer, huge stretches of forest.
Mountains loomed. Far ahead was faint light, a few miles of "twilight
strip" much as that on the planet Mercury.

The Professor was heading for this strip but Mark didn't think they'd
make it. They were losing altitude with sickening speed. Mark had
a final vision of the little Professor tugging desperately on the
deceleration lever, of huge greenish-gray plants coming up beneath them.

Then a rending crash, a confusion of flying legs and arms. Just before
Mark blanked out he knew their ship was still ploughing forward.


                                  III

He came back to consciousness with a feeling of intolerable weight
pressing him down. It was his own weight, he discovered as he tried
lifting his head to look around. It was a terrific strain and he let
his head fall back.

None of the men were seriously injured. The bulging harness had saved
them. They called out to each other, but couldn't move except to roll
their heads from side to side.

"Professor, did you say a gravity equal to that of Jupiter?" Dethman
called out.

"That, or more. And yet this planet has a diameter of scarcely a few
hundred miles! Strange!"

"Strange, he says," came from Driscoll. "What do we do now, just lay
here for the rest of our lives?"

"Let's see you do anything else," Kaarj said drolly.

"Not me," Janus spoke. "You think I'll let this pee-wee world get me
down? If I can only get to that Tuner control."

"I'm afraid this is one kind of gravity it won't counteract," Brownell
admitted ruefully. "This world must be condensed as tightly as a white
dwarf star! A cubic inch of matter weighing hundreds of pounds!"

Mark twisted his head around, saw Janus' huge frame struggling to move.
He was a powerfully-built man, he'd be the one to do it if anyone did.
Slowly, minutes at a time, he managed to drag one leg under him and
then the other. He brought his hands into position. Sweat broke on
his brow as he rolled himself over on all fours. Then with a terrific
effort he hoisted himself erect!

He stood there, a straddle-legged, red-bearded giant. But only for
a second. His legs buckled. He managed to hurl himself toward the
starboard port, as he slid downward.

"At least I can see out now," he gasped. "We just did reach the
twilight strip. There's a whole forest of great big green things,
thirty feet high. Sort of like cactus, flat and spiny."

"They must have helped break our fall!"

"You said it! I can see a strip for over a mile, where we mowed 'em
down. Hey! Look! For the love of--" Janus' voice dwindled off in
amazement.

"Damn it, man, how can we look? What is it? What's out there?"

"People! Dozens of 'em! They're coming out of the forest. Oh--oh,
they've spotted us. But they're not coming over. They just stand there
jabbering and pointing."

"People on this world," Brownell muttered his amazement. "What are they
like, Janus? Describe them!"

"They look kind of savage to me. Squat and furry, but they stand erect.
Their legs are thick and heavy like an elephant's."

"Yes, that would be natural on this world. The terrific gravity."

"Gravity doesn't seem to bother them," Janus went on. "Let's see, now.
Yes, in all other ways they seem to be low-evolutionary humans,
except ... good Lord!"

"Except what? Damn it, Janus, go on!"

"They have knobs!"

"What?"

"Knobs! Growing right out of their foreheads. And they're lit up--the
knobs, I mean. Sort of a soft white light."

"Another logical development of nature," said the Professor. "They live
on the dark side, so their bodies manufacture the necessary light. Are
they armed?"

"They are. Just crude spears and clubs, though, so I guess we're safe
enough in here. Oh, oh, here they come. I think they see me!"

Twisting his head around, Mark could barely see a corner of the window
where Janus lay. In the twilight gray beyond he glimpsed the horde of
barbarians rushing at the ship. It seemed fantastic that they could
move in such gravity, fantastic that any creature could walk.

One of them hurled a spear with deadly accuracy. It struck the window
and glanced away. Others crowded around, pounding at the glass with
clubs, clamoring to get at Janus who lay just beyond.

"Professor," Janus said wryly, "this isn't very pleasant. Are you sure
that glass will hold?"

"Don't worry. It will take more than their pounding to crack four
inches of crystyte."

"Hope you're right." A moment later Janus exclaimed, "Hey, some
of these babies have electric rifles! Good Lord, I see--one, two,
three--at least half a dozen of 'em! Wait a minute, though--they're
only using them as clubs. The metal parts are corroded. Why, those are
the old-type electric rifles popular on Earth two hundred years ago!"

"You must be having delusions," came from Ferris.

"No, I'm not. I've seen that type of rifle in the museums. Now how do
you suppose they got 'way out here?"

For a few minutes there was silence, broken only by a faint ringing
sound as the clubs beat against the thick crystyte. Then Janus
announced:

"Here come more of 'em out of the forest. They're bringing up the
reserves. Hey, this might be serious! They have a new kind of weapon."
He peered for a moment into the grayness. "It's a huge thing, seems to
be a sort of combination catapult and cross-bow. I don't like the looks
of it."

A minute later the first shot came. It struck the spaceship very close
to the window. There was a muffled explosion, and a flashing blue flame.

"By all that's holy--explosives! Powerful stuff, too. These babies
aren't as barbarian as they look!"

"We've got to get away from here some way." Brownell was really worried
now. "Janus, do you think you could make it to the controls? Perhaps by
dragging yourself--"

"I'm sure gonna try it! Wait a minute, though--they're not going to
bother us any more. They're scared!"

"Scared of what?"

"Damned if I know. They're staring off to the right, jabbering and
pointing. Hah! There they go, they're running away!"

Driscoll said, "What did you do, Janus, make a face at 'em? That red
beard of yours is enough to scare anybody!"

"Something's coming." Janus was straining his neck now, his face
flat against the glass. "I think I can make it out ... yes ... holy
blazing comets! What kind of a world is this? Get away from there, you!
Hey--cut that out!"

Janus' voice had risen to an excited pitch. "Get set, men--I think
we're leaving here!" The ship gave a sudden lurch and Janus rolled
backward. His head hit the floor hard--enough to stun him a little.

And now their ship was moving! Not upward. It seemed to be dragging
forward over rough terrain. In this tremendous gravity, every slightest
jolt bruised them horribly. They could only lie there and take it.
After five minutes of this their muscles seemed pounded to a pulp,
despite the inflated suits still encasing them.

Then as suddenly as it had begun, the movement stopped. There was
ominous quiet.

Mark, on the brink of unconsciousness, thought he was dreaming when
he saw Professor Brownell leap to his feet! Now the other men were
stirring. They rose dazedly. Gravity was normal!

They crowded excitedly around the windows. Outside was bright daylight,
no longer the twilight haze. The barbarian horde wasn't to be seen, nor
was--that _other_. Whatever it was Janus had glimpsed.

Janus groaned a little and sat up, rubbing his head. They questioned
him eagerly.

"Maybe I didn't see it," he muttered. "You wouldn't believe me anyway.
Gravity's normal, so let's get out of here."

And when they pressed their questions, he only shook his head
stubbornly.

Heedless of their aching muscles, they zipped out of the bulging suits.
Mark's hand went instantly to an inside pocket near his heart, where
he'd placed his secret flat box with the lenses. He was relieved to
find that it, at least, was undamaged.

       *       *       *       *       *

Janus was breaking out the weapons. He handed each of them an atomic
rifle and neutro pistol. Brownell had taken a sample of the atmosphere
and announced it was fit for them. They debarked onto a plain where
lush yellow grass sprang waist high.

"Strange," Brownell was muttering. He stared back the way they had
come. Only a few yards behind them was the twilight zone! It was
sharply defined, gray and misty, reaching sheerly up. Yet they stood
in bluish daylight which extended ahead of them to the sharp, downward
curve of the horizon.

Brownell walked slowly back to the twilight zone, gingerly testing the
gravity. He entered the zone--and fell flat to the ground! Janus leaped
to him, dragged him back.

"Did you ever see such a thing?" Brownell exclaimed as he rose. "Not
only is there a sharp division of light and dark, but half the planet
is terrifically heavy while the other half is normal. It defies all
laws as we have known them."

Janus was peering intently into that grayness--toward the edge of the
forest a hundred yards away. Suddenly he gripped the Professor's arm.
His voice came a little hysterically.

"I wasn't dreaming, then. I see it! There it is--the thing that grabbed
our ship! Don't move, you men, because I swear--it's watching us!"

Gradually they made it out, as they stared in the direction of Janus'
gaze. It was a huge bulking shape that towered above the tallest trees.
A roughly round, metallic body that rested on four jointed metal legs.
Metal arms, too, dangled at its side.

"A robot!" came in a whisper from Dethman's lips. "A metal robot, but
good Lord--look at the size of it!"

They were looking. Fifty feet above the ground they could make out its
head, semi-spherical--and there were two eyes glowing with a greenish
light, eyes that must have been large as dinner plates! It stood quite
motionless in the gloom near the forest, watching them.

"That's the thing that towed us here?" Brownell whispered.

"Yes! I just got a bare glimpse of it."

"Must be friendly, then. But I wouldn't want to shake hands with it!
The thing does seem to be watching us, doesn't it?"

"I'll fix it!" Ferris suddenly brought his rifle up, took aim at the
glowing eyes.

Janus whirled, knocked the rifle aside. "You fool! That's an
intelligent entity, I tell you! Want to get us killed?"

As though it had seen and comprehended the action, the robot's eyes
blinked once or twice. It was eerie. Then it raised one of its arms and
seemed to gesture--not at them, but beyond them. With that, it turned
and stalked away, crashing through the forest.

"I get it," Mark said thoughtfully. "It was warning us to stay on our
side of the fence!"

"And that's just what we will do. It's the only place where we can
stand up, much less move about."

They walked back to the prow of the ship. "Where does this daylight
come from?" Brownell was still puzzled. "There's no sun. Seems to me
this gravity has something to do with it, too. Say! Do you suppose this
light--"

He never finished, for at that moment they heard a shout ahead of
them, and saw a group of men approaching. They were tall and straight,
clean shaven, and dressed in trousers and tunics of rough texture
but undoubtedly of Earth pattern--the pattern which had been popular
hundreds of years ago! They carried weapons too, the old-type electric
rifles which were so devastating at close range but not very effective
at longer distances.

They came warily at first, but smiled when they saw the newcomers were
not going to cause trouble.

"Greetings!" their leader said in perfect English. "You're from Earth?
We thought we saw your ship crash, and came over to investigate."

Janus stepped forward and introduced himself, shook hands.

"My name is Donli," the other said. He pronounced it that way, crisply,
running the syllables together. Mark suddenly wondered if this could be
a contraction of "Donnolly".

       *       *       *       *       *

Donli and his men were speechless for a moment, staring in turn at the
spaceship, the new-type weapons, and Ral Kaarj.

"You have never seen a Martian before?" Kaarj grinned at them in a
friendly manner.

"Pardon our staring," Donli replied. "We have never seen a Martian, nor
such a spaceship as this, nor any other world. We have waited long for
this! Long!"

"You've seen no other world. But you are Earthmen."

"We have been here always."

"I begin to understand," Brownell said. "There are others of you here?
Where do you stay?"

"Our city is only fifty miles from here. We shall be happy if you
accompany us there. We have good roads, and surface cars. Our leader,
Mari, will explain everything to you." Donli paused, glancing nervously
into the twilight strip. "You should be of great help to us against the
Perlacs, with your new weapons."

"Perlacs? Are those the furry creatures with the lights on their heads?"

"Yes. We call them that because Perlac is the name they give to the
world. They have warred on us for generations. We number a mere five
hundred, and they are thousands." Donli looked worried. "And now that
the robots are active again, we are in even more danger."

"We saw one of those metal giants," Janus exclaimed, "just a few
minutes ago!"

"Yes, we saw it too. We came up just as it was stalking away. It's the
first we've ever seen, but we have heard much about them; the stories
have been handed down. There is supposed to be a great temple on the
dark side, where the robots are housed."

"More of them?" Mark exclaimed. "I hope they stay over there, then!"

Donli shook his head. "This I know: if the robots are roaming again, as
they did many years ago, none of us will be safe."

"Then let us go to your city," Brownell put in. "We should be able to
lift gravs now, if the Tuner hasn't been damaged."

It hadn't been. In a few minutes they were winging low across the
plains to the horizon.

The city bore the unusual name of "Frell", and lay semi-circularly at
the foot of a sharply rising hill. People were seen, men and women
alike, working in the surrounding fields.

Donli led them through the main street. The buildings were of a dark
substance that might have been earth compressed to concrete hardness.
They entered the most imposing of these buildings, and thence to a huge
room which was almost the size of a theater on Earth.

"Make yourselves at ease," Donli said, "while I summon Mari. She will
probably be at the laboratories now."

"Mari," Driscoll said, when Donli had gone. "So their leader is a
woman! And they have laboratories!"

They gazed about them. The curious daylight came through windows
of glass or similar material. There were chairs and tables of
finely-wrought metal. Along one wall were bookcases filled with charts
and uniquely-bound volumes. There were other volumes too, which seemed
vaguely familiar.

Brownell walked over there.

"Look at this! A whole case full of books from Earth--scientific,
technical books, all of them!" He read a few of the titles on the faded
bindings. "These were all popular hundreds of years ago. And these
others," he waved, "are probably the entire recorded history of these
people. I'd give anything to look into them." He didn't touch the
volumes, but remained thoughtful.

Mark too was thoughtful. "Frell," he mused. "A strange name for this
city. Seems as though it ought to mean something, but I can't quite
place it."

       *       *       *       *       *

Donli returned soon, accompanied by Mari. She was tall, lithesome, her
features classical and still beautiful despite smudges of sweat and
grime from the laboratory. Her golden hair was braided into a halo
which gave a queenly appearance, and her eyes were bluer than the
strange daylight of this world. Skirt and tight-fitting bodice were of
rough texture but dyed a rich golden color.

Involuntarily the men gasped, but Mari did not mind that or their
stares. She seated herself and bade them be seated opposite her. Then
she leaned forward, searching their faces. Not until then did they
notice that her eyes were cold, suspicious.

"You have come from Earth, of course. And Donli tells me this strange
one is Martian. Who is leader among you?"

"Why, I suppose I am," Janus said. "Either me or Professor Brownell,
here."

"Professor?" Her mind seemed to grope for the meaning. "Ah! That word
means a man of scientific learning, does it not?"

"In this case, yes," he answered.

Brownell spoke softly. "Madam, we come in peace. We want to be friends
and we want to help you, if we may. You need have no suspicion of us."

"No suspicion? You come from the dark side! From the Perlacs!" She spat
the last word venomously.

Donli, standing there, seemed troubled. He said:

"We only found them near the twilight zone. They were most friendly in
manner and speech! They seem--"

Man waved a hand, and he was silent. She said:

"Men of Earth, you wonder why I am suspicious? Know, then, that we
observed your ship five days ago, crossing our land with tremendous
speed and heading for the dark side! Why have you waited until now
to come here? It could be that you have allied yourselves with the
Perlacs! Have they sent you here?"

There was a moment of stupefied silence. They could scarcely believe
that she was serious, but her cold manner assured them of it. Then the
answer must have dawned on all of them at once.

"Ketrik!" Janus boomed, hoisting his big frame from the chair. "By all
that's holy, he did reach here! She must have seen Ketrik's ship!" Then
he sobered. "But--if it was streaking for the dark side, it was surely
out of control. Ketrik must be dead by now. To think I'd live to see
the day when that man blanked out."

Mari had drawn a strange looking pistol from a belt at her waist. She
gestured with it now and said:

"Be seated, please. We will talk yet a while. This Ketrik--he is
another one from Earth?"

"Yes, he came before us. Came alone. We only landed here today, a few
hours ago! Believe me, we want no part of those Perlacs. We had a
little trouble with them."

She seemed relieved, and satisfied at last. "Forgive my suspicion of
you. But where the safety of my people is concerned, I cannot be too
careful. We have had trouble with the Perlacs, always. The greatest
trouble is yet to come and it is brewing fast." She appeared to be
marshalling her thoughts, then she went on:

"We are the seventh generation of a party of Earth people who arrived
here hundreds of years ago. My direct ancestor, Wilm Frell, was leader
of that expedition. Our city is named in his honor!"

"I've got it!" Mark exclaimed. "She means William Farrell! The Farrell
expedition was one of the earliest and most ambitious interstellar
attempts. Men had already reached the moon and were trying for Mars.
Farrell set out with a hundred men and women aboard--"

"A hundred and forty," Mari corrected. "We have his log here. They
missed Mars, their compasses were wrecked in the asteroids and they
continued outward for months, finally crashing here. We still do not
know what planet this is!"

"You're beyond Pluto!" Brownell told her. "But how could they have
survived a crash on this heavy world?"

"It is one of the miracles. The records tell of it. They landed near
the light! The light at that time encompassed a very small area, only
a few miles. Gravity there was normal, but beyond, it was very heavy.
They investigated the center of light and found the Stone."

       *       *       *       *       *

Brownell was excited. "I suspected something like this! The Stone? What
is it?"

"We still do not know, except that it supplies us with light and normal
gravity and a temperate zone very favorable to our crops. It defies our
science, and it certainly must have come from somewhere far beyond our
solar system! Our ancestors found it deeply buried and dug it out. The
moment they did--"

"Yes?"

"The light from it spread slowly, very slowly. In about ten years' time
it had encompassed this entire hemisphere, stopped only by the sharp
curvature of the planet."

"And as the light spread outward, the heavy gravity vanished?"

"That is true. We have the Stone now atop our hill, which is the
highest spot. Our ancestors, however, had to fight for it time and
again. The Perlacs at that time were really savages. They had known of
the buried light but were afraid to approach it. Later they tried to
get the Stone, but were always driven back into the darkness. They
have warred on us ever since--for generations!

"In the last few years they have become very strong. They are using
explosives now. I believe that ages ago, long before the first Earthmen
came, a civilization existed and died here. The present Perlacs must
have discovered remnants of an ancient science, and are slowly reviving
it!"

There was a moment of silence. Janus took advantage of it to hand his
atomic rifle to the girl, and his neutro-pistol as well.

"Have you ever seen weapons like these?"

She examined them excitedly, especially the neutro-pistol. "Donli, look
at this!" she pointed at the firing coils. "It seems to be the same
principle we're working on!"

"Do you mean to say you're trying to invent a neutro gun?" Janus was
amazed.

"Yes," Donli answered. "We've been working on it for the past several
years, but it's been slow and hard. Sometimes disastrous." He stepped
to a bookcase, brought out one of the ancient volumes. It was Spurlin's
_Evolution and Control of the Free Electron_.

"We've worked from the principles set forth here," Donli explained,
"and with some slight measure of success. But we feel that we're
treading on dangerous ground. Only a few months ago one of our
laboratories was blown up and four men killed."

Brownell nodded. "Even when Spurlin wrote that book there was no real
control of the electron. It came later. Anyway, we can help you now!
We have the real models here to work from. Would you like to see these
guns in operation?"

It was a needless question. They repaired outside, where Janus
demonstrated the atomic rifle first, aiming at a harmless clump of
bushes some fifty yards away. The atomic pellet struck and exploded,
leaving a miniature crater.

"That," Brownell said, "is an example of uncontrolled atomic explosion.
Rather crude, but it serves its purpose. Now let us observe a
refinement of it. _Controlled, electronic action._"

Janus aimed the pistol. A bluish, pencil-thin ray leaped forth. Where
it touched, substance vanished into a froth of flame. The ground
itself became incandescent glass. The ray remained constant so long as
his finger touched the firing stud.

Mari was excited. "Then you will help us perfect ours? The Perlacs are
becoming stronger than we have ever known them, and whenever they start
scouting the twilight zone, it means trouble. Donli tells me the robots
are active again, too!"

"We can and will help you," Brownell assured her. "I doubt if those
overgrown robots will stand up long under an electronic ray!"

The Professor was eager to see the Stone, and Mari graciously
accompanied him to the crest of the hill where it was housed. The
others, meanwhile, went with Donli on a tour of the shops and
laboratories.


                                  IV

Brownell told them later, in great excitement: "I swear to you, it
defies all physical laws as we know them! It's merely a shiny chunk of
rock, a few yards in diameter--but do you know, I believe it actually
feeds upon gravity! I have always believed that gravity, magnetism,
and other such universal forces are all a part of the electrical
spectrum. Some peculiarity in the atomic structure of this Stone draws
the straight-line force of gravity to it, and that force is then
oscillated, transmitted into light! The process is unending!"

"That's all very well," Mark told him, "but I believe the greatest
miracle is right here in the laboratories. These people have had to
utilize the barest elements of this world, but they've done wonders.
They have plastiglass, and farm implements, and electrical power--even
crude atomic furnaces."

"They'd have their neutro-pistols right now," Janus agreed, "but they
hit the same stumbling block that baffled our scientists for so long."

For days they worked ceaselessly on the neutro-pistols. Mark and the
Professor together laid out the blueprints, devising a radical and more
potent design for the firing coils. The latter was surprised at Mark's
knowledge of electronic principles.

"I may surprise you even further, one of these days," Mark promised.

And now the urgency of their work was really impressed upon them.
Scouts returning each day from the twilight zone reported that the
Perlacs were gathering. Thousands of them swarmed the forests on the
dark side, apparently massing for an all-out attack. There had been a
few preliminary skirmishes but nothing serious as yet.

Donli undertook the task of setting up barricades at the twilight
border. These were huge shields of light but durable metal, arranged in
strategic positions, easily movable. And the work at the city went on
apace.

Janus and the others directed work at the forges and metal shops.
Everyone, men and women alike, who could be spared from the border
defenses, were given assignments. Mari was a surprise to the new men.
Already she knew the ancient science textbooks by heart, and she
thirsted for more knowledge. She was everywhere, directing, helping,
learning. She grasped the principle almost at once when Brownell
explained:

"Briefly, the atom itself must not be shattered. That has been
your mistake. Successive sheathes of electrons must be stripped
without disruption of the ultimate atomic structure. That means
swift transmutations, not disintegration. Most important of all, the
electrons must be propelled along a controlled, directional beam."

Only Ferris was dissatisfied at the hard work. In their quarters, at
the end of the first week, he complained:

"What's all this getting us? I thought we came out here to make a
fortune! That's the story you gave me, Janus, when you rooked me into
this deal."

Janus looked at him distastefully. "Haven't you ever wanted to do a
decent act in your life? Lord knows I've done some scandalous things,
but these people need our help now and they deserve it!"

"That's not getting back the fortune I sunk into this venture," Ferris
grumbled.

"We'll think of that later."

The work was slower than they wished, for it became apparent the Perlac
attack was going to materialize any day, any hour. As leader of the
defense, the all-out call was left to Donli, who, with his select
group, remained at the border constantly now.

And on the tenth day, even before the new pistols had been assembled or
tested--the call came. One of the scouts raced into the city with the
signal.

       *       *       *       *       *

Everyone, men and women alike, left their work instantly. Dozens of
the electrically-motored surface cars were waiting, and soon they were
racing along the road. Within the hour they had reached the twilight
zone to reinforce Donli's group.

Each person was equipped with an electric rifle which, at the longer
distances, stunned but was not fatal. And there were quantities of
atomic grenades. The new Earthmen retained their atomic rifles and
neutro-pistols, as they better understood the operation of these
weapons and could use them to more advantage.

The attack had not yet come but Donli was expecting it at any minute.
Each group took up its assigned position behind a barrier. Mark found
himself beside Janus and was glad, for he liked that blustering,
red-bearded giant.

"It's going to be hell," Janus promised, peering into the twilight
gloom. "We have to wait for them. The Perlacs can come over into our
lighter gravity, but their gravity'd be fatal to us!"

Mark nodded. "It means we'll be fighting a strictly defensive battle."

The twilight beyond faded into the darkness of the huge forest, and not
a Perlac was to be seen. Not so much as a moving shadow. But they were
there, Mark knew, thousands of them; and when they came it would be
silently.

And silently they came. Mark's first intimation was the explosion of
grenades far down the line, and then he saw them--hordes of Perlacs,
heavy of limb, but coming with amazing speed. Most of them were using
cross-bows, and Mark realized that some of the shafts were equipped
with metal-tipped explosives. Then he was too busy for further
observation, as he brought his atomic rifle to bear.

The old style electrics were at work too, all along the line; and
the grenades blasted huge gaps in the advancing tide. But still they
came, moving now across the lighter zone. Thousands hadn't been an
overstatement! The dark tide came rushing over their stunned and dead.

And now those explosive tipped shafts were having effect. Several of
them struck a barricade next to Mark, and tore the metal from the
foundations. Now Janus, beside him, was bringing the neutro-pistol into
play.

Savagely Mark swung his beam in a never-ceasing arc, exulting at the
swath it cut before him. Further down, Driscoll, Kaarj and the others
were doing the same. Together with the grenades it seemed to stem the
tide, but only for a moment.

"Keep it going! Keep it going!" Janus was yelling. "These beams are
good for hours!"

The very silence of the attack made it the more terrible. No yells, no
screams of fury came from the heavy-furred Perlacs as they littered the
terrain by the score.

Then, as suddenly as they had come, they retreated. The seven sweeping
beams had done the work well, but in an unexpected manner. Flames were
leaping in the lush grass between the defenders and the forest!

"Respite!" Janus yelled. "Ten minutes, maybe. They'll be back when that
grass is burned down!"

But there was no resting now. A score of men were dead and twice that
many wounded, who had to be carried back from the battle line. Three of
the barricades were wrecked, and they strove to get these into place
again.

Mark noticed Mari, sweat-grimed and weary, her golden hair streaming
down. But she was magnificent still, a tower of strength as she hurried
along the line giving aid and encouragement to her people.

"I wonder where the robots are?" Mark suddenly remembered as he
worked beside Janus. "If the Perlacs have learned to reactivate those
monsters, as Donli thinks--"

"Encouraging, ain't you? As if we're not having a hard enough time as
it is!"

And then Mark remembered something else. Remembered so suddenly that he
began laughing, a little wildly, and Janus slipped him a light one on
the jaw.

"Come out of it, lad! None of that, now--we're not licked yet!"

But Mark had reached to his inner pocket, and brought out his secret
flat box. "Remember this, Janus? Good Lord, but I ought to be blasted
for forgetting it! You always knew it wasn't a camera--well, now you're
going to see it in action!"

"Good, lad! I hope you've got something there. Here they come again!"

       *       *       *       *       *

This time the Perlacs had massed their forces, and they came in two
wide flanking movements aimed at the ends of the barricades.

"Let them get close," Janus passed the word to the men, as they hurried
down to the left. "Then give them your grenades--all you've got!"

Grim-faced they waited. Mark once more touched the release stud on his
box, exulted as the coils hummed into power.

"Now!" Janus yelled at last, and swept his beam into play.
Simultaneously the grenades rained outward. The terrain erupted in
geysers of blackened grass and fleshy fragments. But determinedly the
Perlacs came, and their cross-bow shafts filled the air.

Despair began to touch the Earthmen now. It was obvious the fanatical
Perlacs were going to make this a war to extinction, and there could be
but one final result. The Perlacs outnumbered them a hundred to one. If
only they could have gotten the new electronic weapons ready in time!
Even their grenades were running low now.

Grim-lipped, Mark waited for the next onrush. He passed his neutro to
a neighbor and concentrated on his box. Its power had been proven in
minor tests, but this would be the maximum!

The wave came. More of them now than before. Mark stepped for a moment
into the open, heedless of the shafts. The box, held waist high, looked
for all the world like a camera....

But the result was devastatingly different!

The men felt a violent holocaust of air around them, rushing away from
all sides. For seconds they couldn't breathe or move! The temperature
dropped so suddenly that they were literally frozen where they stood!
Then warmer air came pressing in again but still they didn't move,
because now they were staring--staring at the miracle.

In a hundred-yard area before their barricade the mass of Perlacs
were motionless, many of them arrested in grotesque postures! Others
had literally burst outward. But all were dead, and now they began to
topple over, like frozen statutes!

Another wave was coming behind, just beyond the area. Now they wheeled
and fled for the forest. Quickly Mark adjusted the sights and gave them
another burst. The same thing happened. The rush of air, the sudden
drop in temperature--and the horde was a mass of frozen corpses. But
this time, the box became hot in Mark's hands, burning them severely,
and he quickly dropped it.

At the other end of the line the defenders weren't doing so well.
The Perlacs had gained that end of the barricade, and the battle was
furious and to the death.

"Come on!" Mark raced for that end, followed by the others. But now
Mark couldn't use his weapon, for it would mean blasting Earthmen and
Perlacs alike!

And then, fantastically, the battle seemed to hang poised.

There came a grinding, shuddering sound. A series of these sounds.
The ground seemed to vibrate, and then along the twilight strip came
a towering, stalking, fifty-foot shape. One of the robots! It came
swiftly, purposefully, huge eyes glaring down--straight for the battle
line!


                                   V

"This does it," Janus groaned. "That thing looks mad!" But no other
robots came, and he raised his beam-pistol in readiness as the great
monster came bearing down.

"Hold it," Mark caught his wrist. "Hold your fire, men!"

For the Perlacs were fleeing! Forgotten now was the fury of battle as
they raced _en masse_ back to the darkness of their forest!

And abruptly the robot swerved in its course, went after them with
purposeful strides. It bent down a little and swept huge, claw-like
hands close to the ground. A few of the Perlacs were caught, dashed to
the ground, never to rise. Almost gleefully the metal monster trampled
down the edges of the forest. The Earth people could only watch
wearily, numbly. It was over. Unbelievably, the battle was over.

Tiring at last of its mad sport, the robot turned and came striding
back. Heedless of Mark's warning, Mari stepped forth and faced it
defiantly, rifle held in readiness. Tall and straight, her golden hair
tumbling down, she was a defender of her people to the last.

And the robot paused! Only for a second, during which it seemed to be
surveying her. Then it came on, but stopped some twenty yards away.

Then it spoke! The voice was rasping, metallic, but the words were
unmistakable:

"Hi-ya, bud. What's cookin'?"

Janus' voice was a ridiculous gurgle in his throat. He took a step
backward and his eyes bulged. For the thing had seemed to be addressing
_him_!

At last he got the words out: "Ketrik! By all the red-tailed Zigs
on Venus, it's Ketrik! Only he could use an archaic expression like
that--what's cookin', indeed!"

There came a rumble of metallic laughter.

"Hi-ya, Janus! Haven't seen you in years. And Kaarj! Last time I saw
you was on Deimos, when I robbed the temple of ancients. How are you,
kid?" The robot went down, extended a long metal finger as big around
as a man's arm. Kaarj retreated hastily!

"Well, ain't any of you glad to see me?" the voice came mockingly. "And
after I saved your battle, too!"

"Sure, we're glad to see you," Janus replied shakily. "But good Lord,
man, come down out of that thing so we can get a look at you!"

"Hell, no. I'm havin' fun! Anyway, I'm not up here. Not the real
Ketrik. My body's lying in an alcove back there at the temple of
robots."

Mari had come to stand beside Janus. Her face was flushed from the
recent battle, but some of her defiance had fled. The robot bent closer
still, seemed to be peering. Then came a long whistle, metallic but
shrill, and one of the huge eyes winked!

The girl seemed to recognize that primitive sound and her face turned a
deeper red. But she stepped a pace forward.

"Mister--ah--Ketrik, you have saved my people and have earned our
undying thanks! But what about the Perlacs--do you think they'll be
coming back again?"

The robot chuckled. "Not for a long time! Certainly not when they know
I'm around. Those babies have given me a wide berth so far." He added:
"I've been intending to pay a visit to your side of the world, but I
could tell those dark-skinned brutes were up to something. I decided to
hang around and await developments."

"But Ketrik"--Janus hesitated--"what's this about your body?"

"Don't worry, it's safe. This is only the mental part of me. Sure,
there's a huge temple about ten miles back, with dozens more of these
robots standing around idle." A sudden thought occurred. "Want to take
a look? I could carry you across the heavy gravity."

"No thanks!" Janus declined. "My scientific interest doesn't go that
far. Maybe the Professor, here--"

"Sure!" Brownell came forward, eager.

"I'll go too," Mark said. "I'd like to see how those robots work."

Ketrik extended a huge hand. Brownell and Mark clung tightly as it
swung them up. With the two men perched on its shoulders, the robot
went striding back through the forest.

The temple, massive and pillared, rested in a wide clearing.

They saw the robots, dozens of them lining the walls. The quartz discs
of their eyes were now dull and lifeless. And near each robot, fifty
feet high in the wall, were alcoves.

"Gravity here is normal!" Mark noticed suddenly.

"Yes," Ketrik replied. "That's probably what saved my life. I crashed
right through the roof!"

They saw Ketrik's spacer on the floor below them, its nose and forward
tubes crumpled beyond recognition.

"I'll show you my body." He strode to one of the alcoves, and the men
stepped from his shoulders onto a stone ledge. Before them was a thick
glass coffin. Resting in it was the material Ketrik!

       *       *       *       *       *

It was a large body, as large as Janus, but clean shaven. The blue eyes
were open and staring, and even in this suspended state there seemed to
be a quality of recklessness, even amusement, about them.

"How do you get the mental self into the robot?" Brownell asked.

"Damned if I know how it works," there was almost a shrug in Ketrik's
robot voice. "I just experimented with the thing."

He just experimented! Mark marvelled at this man.

"Don't touch it," Ketrik warned, "but you'll notice there are two
cathodes attached to the temples of my earth body. See how the wires
lead out, and up to that panelled board on the wall? There are all
kinds of coils and things behind that board. Those other cathodes, that
you see dangling, were attached to the brain plate of the robot. I
suppose the molecules of your mental self flow through the wires. When
the transference is complete, you merely detach the cathodes and start
walking about, a full-fledged robot! I tell you it's wonderful!"

"Ketrik," Brownell said, as they went back through the forest, "we
should be returning to Earth as soon as we complete the new weapon for
Man's people. Don't you want to return with us?"

"No, I think I'll stay. I want to be sure those Perlacs don't cause any
more trouble for a while."

"There wouldn't be any other reason?" Mark grinned.

"There would and is." The smile was in Ketrik's voice, if not on his
metal lips. "I like that golden-haired Amazon--what's her name--Mari?"

"But why return at all?" Mari wanted to know, when the Professor
announced the plans. "You have said you wanted a base for the
manufacture of your Frequency Tuners. What better place than here?"

"Thank you, my dear. I had thought of that, but after all this is your
world, and we are intruders."

Mari was hurt. "After all that you've done for us? And you can do so
much more!"

"Then rest assured we'll be back, possibly within a month. True, there
is much to be done here but we need new supplies, tools, equipment of
every sort."

Janus said: "And with your permission, we'll want to bring back some
new men. Not rogues and adventurers like me, but scientific men who can
come here and work out their ideas without fear of that stupid Earth
Bureau. Men like Mark, here, and the Professor."

Brownell nodded agreement. "I see a new regime. The Tri-Planet Council
will have to cooperate with expanding endeavors, or take a back seat.
Already I know two men on Earth, and four on Mars, who'll be delighted
to come here to carry on their work. And Mark, that reminds me. That
new weapon of yours. I think we can ask about it now?"

"Oh, it's nothing much, but I wasn't going to let the Bureau have it on
their terms! It's merely an advanced frigidation idea. Works along an
extended magnetic beam, absorbing all heat in a given area, almost to
absolute zero."

"And he says it's nothing much!" came from Janus.

"It still needs some working out. The coils didn't stand up, the last
time I applied it out there."

In two more days they were turning out the neutro weapons in quantity.
During that time nothing more was seen of the Perlacs, as the
robot-Ketrik maintained a vigilance. Brownell made a last check-up of
the spaceship, and more important still, he strengthened the Frequency
Tuner to counteract the gravity.

       *       *       *       *       *

On the last night, Mark tossed restlessly in his bed. He could not
sleep, and he didn't know why. Was it something they had forgotten?
He didn't think so. Nevertheless he had a preternatural awareness of
something wrong....

He arose, dressed quickly. There was never "night" on this side of the
little world, but the rooms were automatically dimmed. Silently he
tip-toed through the rooms. Brownell was there, sleeping peacefully.
And Janus, and all the others.

No! Ferris was gone.

Mark's heart leaped. He had never liked that man, never quite trusted
him. Now it came back. Ferris' eternal harping about the fortune he had
put into this expedition.

If that little rat was planning--Mark hurried outside. The city was
deathly quiet, immersed in sleep. The eternal light struck his eyes
and brought him fully alert. He hurried along the street toward the
outskirts, toward the base of the hill where the spaceship waited.

As he neared the hill, he spied Ferris. The man was coming down the
slope. Ferris saw him, and waved a hand in greeting.

"Hi! Is it you, Travers? What's the matter, can't you sleep either?"

Mark's steps slowed, and he breathed in relief. He'd been wrong. After
all, the man had a right to be up.

They met near the spaceship, and Ferris waved a hand toward the crest
of the hill. "I was just looking at the Stone. It's the damnedest
thing!"

"Yes. Brownell tells me--"

Ferris' hand moved like lightning. Mark found himself staring into the
stub end of a neutro-gun. Ferris was no longer smiling and casual.

"In!" he snarled. "Get in there--quick!" He gestured toward the ship,
and Mark noticed the door was open. He moved toward it slowly, then
paused, started to turn.

"I'll blast you, Travers!"

Mark shrugged, entered. Ferris came quickly behind him.

"That's better. I don't want to rouse any of the others. Sounds carry
far on this world." He paused and grinned, with all but his eyes.
"Sure, Travers, I was looking at the Stone. I'd like to get it back to
Earth, but it's too much for me. Guess I'll just have to be satisfied
with the Frequency Tuner. The Bureau of Inventions will pay me a
handsome price for it, no questions asked."

"You sneaking, double-crossing rat," Mark said slowly. "You'll never
get away with this!"

"_This_ says I will," Ferris sneered, gesturing with the neutro. "And
since you came snooping out here, I'll just take that new weapon of
yours."

"It doesn't work any more."

"I'll take it anyway. Hand it over. Careful!"

Mark shrugged, tossed the box-like weapon to him. But his mind was
racing. Ferris had the upper hand, all right, and he _would_ get away
with this if Mark didn't do something quick. Mark glanced around. They
were in the control room, and he knew the Frequency Tuner was ready. He
said:

"What about Brownell--Janus--the others?"

"What about 'em? They wanted to come out here, so let 'em stay.
Yeah--for the next hundred years!"

"What about me?"

"You know, I think I'll just take you along--for a short distance,
anyway."

Mark's voice was taunting. "Because you're not quite sure how to handle
this Frequency control. You'll need me."

"And that's where you're wrong. I've studied it plenty. It's easy!"

Mark dropped suddenly to his knees, and with the same movement his body
lashed forward--low and hard. He heard the neutro sing, and felt the
swirling heat of it over his shoulder. But Ferris was quick. He danced
lithely back. His right hand with the gun in it came swinging up.

The heavy gun caught Mark squarely under the chin.

       *       *       *       *       *

He came struggling back to consciousness, aware that he was still lying
prone. He allowed his brain to clear before opening his eyes, but
already he could tell they were in space.

He thought of his friends on Perlac--stranded! It would be a miracle
if they ever succeeded in building another spaceship there, with their
limited equipment.

"Hi, Travers. We're on our way. So I can't handle the Tuner, eh?"

Mark groaned, rolled his head a little, feigning grogginess. But he was
alert now, and he cursed himself for a fool for underestimating Ferris.
He heard the man's voice go on:

"And to show how much I need you, I'll just toss you out somewhere
between Perlac and Pluto. Or maybe between Pluto and Neptune. Which
would you prefer?"

Mark's heart leaped. They couldn't have come far, then! He was lying
near the control-console and he knew they were on robot control. Ferris
must have set the course already. He was confident now, watching Mark,
for he knew it took minutes to adjust that complex set-up.

Mark stirred, grasped a metal stanchion to help hoist himself erect.
His plan was made. To the right of the console was an auxiliary unit,
feeding emergency power to the Tuner. He wondered if Ferris knew of
it. He glimpsed Ferris coming toward him. Mark surged erect, his right
hand darted out. It came down in a full sweep against the auxiliary
impellator.

The spacer leaped ahead, sickeningly, as acceleration multiplied in a
split second. Mark glimpsed Ferris flying backward. He hadn't time to
see more. Both hands gripped the stanchion now as intolerable pressure
built up. His arms seemed to be wrenching from their sockets. Slowly,
agonizingly, he managed to encircle the stanchion with his left arm.
His right hand seemed to weigh a ton as it reached out. It touched the
impellator stud ... reversed it.

Mark sagged limply forward as acceleration lowered. He hadn't the
strength left to turn his head, see what had happened to Ferris.

When he did, minutes later, he saw a limp figure against the far wall.
The limbs were twisted beyond recognition. The head was crushed. It
wasn't a pretty sight.

Mark changed direction, headed in a sweeping parabola back toward
Perlac. He avoided Brownell's previous mistake and swung wide of the
planet, approaching it from the light side. He landed safely near the
city. The others had already missed the ship, and they received him
joyously.

They left the next day, after a final check-up. Mari had prepared long
lists of items for them to bring back to her people.

The robot-Ketrik was there too, to bid them bon voyage. Brownell said:

"Ketrik, you can reclaim that body of yours. Sure you won't change your
mind and go back with us?"

Again Ketrik resorted to archaic expression:

"Are you kidding?" and he glanced at Mari with his huge robot eyes.

They lifted gravs, and not until they were crossing the orbit of Pluto
did Brownell remember something. He chuckled, said to Mark:

"Suppose Ketrik does transfer again to his body, as he probably will.
How's he going to transport it across that heavy gravity?"

For a moment Mark was startled. Then he grinned and replied, "Well,
don't worry your mind over that. I'll bet you a thousand to one he'll
do it! Positively. That man will find a way!"

1.F.

1.F.1. Project Gutenberg volunteers and employees expend considerable
effort to identify, do copyright research on, transcribe and proofread
works not protected by U.S. copyright law in creating the Project
Gutenberg™ collection. Despite these efforts, Project Gutenberg™
electronic works, and the medium on which they may be stored, may
contain “Defects,” such as, but not limited to, incomplete, inaccurate
or corrupt data, transcription errors, a copyright or other
intellectual property infringement, a defective or damaged disk or
other medium, a computer virus, or computer codes that damage or
cannot be read by your equipment.

received the work on a physical medium, you must return the medium
with your written explanation. The person or entity that provided you
with the defective work may elect to provide a replacement copy in
lieu of a refund. If you received the work electronically, the person

the second copy is also defective, you may demand a refund in writing
without further opportunities to fix the problem.

damages. If any disclaimer or limitation set forth in this agreement
violates the law of the state applicable to this agreement, the

Defect you cause.

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.
