LXVIII, Sept.…" is a scientific publication written in the early 20th century. This volume consists of detailed papers discussing various engineering projects and techniques, specifically focusing on the construction of the East River Tunnels as part of the Pennsylvania Railroad’s New York tunnel extension. It likely appeals to professionals in civil engineering and construction, particularly those interested in tunneling methods, cost analysis, and groundbreaking techniques used in underground constructions. The opening of this publication introduces a paper by James H. Brace, Francis Mason, and S.H. Woodard, which outlines the methodologies and challenges encountered during the construction of the East River tunnels. The authors discuss various aspects of the project, including the contract details, excavation techniques, material management, zoning issues, and the innovative use of shields and compressed air during tunneling. Specific attention is placed on the labor costs and construction processes, painting a comprehensive picture of the engineering practices of the time and the lessons learned throughout the construction period.
