REPORT OF BOARD OF CONSULTING ENGINEERS, PANAMA CANAL. In reference to the Report of the Chief Engineer, Isthmian Canal Commission, February 1, 1905, and the estimates contained therein, it should be remembered that this was in the nature of an emergency report called for on short notice during the visit of the Engineering Committee to the Isthmus at that time. The various estimates were only made after consideration and general discussion with the Engineering Committee-General Davis, Mr. Burr, and Mr. Parsons-and it was the intention that the estimates should be conservative and ample to cover all possible contingencies. It might also be stated that outside of the estimates for the excavation between Bohio and Miraflores, and the Gamboa dam and spillway, all other items were so far as possible based upon the estimates and the unit prices of the former Walker Isthmian Canal Commission, modified to suit changed conditions. 0 37I
