Book excerpt: Excerpt from The Construction of a Small Tunnel When the contractors had full forces, the excavation was carried on by day and night shifts, working ten hours each from both ends of the tunnel. It was but rarely, however, that full forces were employed, as the adjacent grading was more backward than the tunnel and the men were drawn 06 to it. The excavation was all done by hand work, no special tunnel machinery being employed, and it was conducted on the general principle that nothing is so expensive in tunneling as a eave-ia.
