“ The width of the canal is 160 feet at the bottom and 162 feet at the top, through rock, and 110 to 202 feet at the bottom and 200 to 300 at the top, through earthy soil, the actual width in most of the distance being but 100 feet, this being sufficient for the flow of water at the rate of 300,000 cubic feet per minute. The depth is 36 feet, with a minimum depth of water of 22 feet. The cost of the canal up to the time of ‘opening’ was about $33,000,000. ”
