UNIQUE APPLICATION OF HYDRAULIC a certain river there is a high-water period in the spring when a. fair sized ocean steamer could easily manceuver. At the place inquestion there is 22 feet fall per mile, which causes a rapid shipper wanted to transport some material to an island located inthe center of the river at a point where the river was about two-thirdsof a mile wide and the island was about seven-eighths of a mile upstream. He had no power except that which nature was producing,and by means of this and a wire cable about 34 inch in diameter, oneend of which was attached to a tree on the island, the other fastenedto a reel on board the flat boat, which in turn was connected by gearsto a shaft that carried paddle-wheels on each side of the boat, heaccomplished his task. After the boat was loaded, the paddle-wheelswere connected to the reel, which was slowly revolved by the actionof the current and commenced to reel up the wire cable, at the sametime drawing the boat and its cargo up to the island.
