The estimated water required for one lockage on bothsides ^6,249 cub. ft.; and estimating 32 double lock-ages daily, will give 129,479,986 cub. ft. required ; leaving. cupies the lowest existing depression between North andSouth America. • The accompanying illustrations show, in No. 8, a gen-eral map of the canal and isthmus ; in No. 9. a map of thecanal line from Lake Nicaragua to the Pacific Ocean, andin No. 10, a general profile of the line arranged in sec-tions.
