In this picture we have a good view of the east chamber of the lowermost lock, with a partial view of the concrete middle wall. The northern or lower end i:; shown with its coffer lam, i which is a watcr-tight enclosure. Beyond are th" excavating dredges. They are dig- ging o at a channel, 500 feet wide, which ex- tends over seven miles to deep water. The depth is 41 feet or more throughout. A lake is formed at Gatun by a large dam which impounds the water from the Chagres River an. its tributaries. This dam is nearly 1~2 rril"; long, but only 500 feet, or 1 .15 of its length h, will be exposed to the maximum 85 foot water head. The width of the dam will vary from almost a half mile at the base to about 400 feet at the water surface, and 100 feet at its crest. The top of this dam will be 30 feet above the level of the lake, or 115 feet above the level of the sea. Ccp3 rgh.
