The Path Between the Seas

by David McCullough

Wallace was not oblivious to the situation. He had decided at the outset, for example, to provide Panama City and Colón with their own water system (which was the reason for the order of pipe) and to install sewage facilities in both cities. There is even in his organizational headings a basic appreciation of the diversity of tasks to be met other than digging dirt: Supplies, Personnel and Quarters, Buildings and Architecture, Machinery, Maps and Printing, Climatic Conditions and River Hydraulics, Communications. His thoughts, nonetheless, were tied up with the work at Culebra. Only by digging could he train the men, only by digging could he determine his unit cost—“the cost of explosives, cost of loosening and excavating material, cost of loading, cost of transportation, cost of disposition, and the cost of all the various elements of supervision and the maintenance of equipment, track and appliances, on the basis of the cubic yard.” Only by digging could he satisfy Washington with monthly progress reports.
