404 REPORT OF BOARD OF CONSULTING ENGINEERS, PANAMA CANAL.

 It will also prove impossible to continue lockages day and night without any interruptions between the end and the beginning of two subsequent lockages. The French Comite( Technique and the Isthiian Canal Commission of 1899-1901 both reduced the real capacity of a lock to 50 per cent of its theoretical capacity, calculated in the last line of preceding table.
 Each member of the Board may now for himself fix that reductionl, and then multiply the real number of lockages with the average tonnage per lockage he thinks to be correct; in that manner he will easily find the total real capacity of the canal for one year for each set of locks.
 As the Bohio and Gatun locks consist of a double flight of locks, the daily theoretical number of lockages for these locks will be twice the num bers indicated in the last line of the table.
 The favorable supposition is also made that all passing vessels are steamers, and during the lockage will move by their engines.
