VIEW ON THE CHAGRES RIVER.
"This will give you an idea of the work to be performed here," replied Mr. Colné, "and you must remember that it is only one single section of the entire line. Then, too, there are great difficulties in the way on account of the rains, and the sudden overflows of the Chagres River, which crosses the line of the canal. Instead of being a depression to be filled with water, it is liable to pour out at any moment much more water than we want."

"The average rainfall of this part of the Isthmus," said Dr. Bronson, "according to the official reports, is over twelve feet. This is not distributed through the year, but is confined to about seven months. During a single rain-storm six and a half inches of water have fallen.
"The consequence is that there are excessive floods in the rivers; the Chagres River, which you see represented on the map as crossing the canal, is, in the dry season, a stream about two hundred and fifty feet wide and two feet deep. During a heavy flood it is fifteen hundred feet wide, and over forty feet deep, and it has been known to rise thirty or forty feet in a few hours. In these floods it brings down trees, rocks, and earth, and sometimes houses, and the sides of hills. In one freshet, an iron tank, that stood seventeen feet above the railway track, was washed away, and on several occasions considerable portions of the road have been destroyed."
