(new) 50 ---- Total $518 ==== The plant furnishes power sufficient to light the farmhouse and all of the buildings with electricity, as well as those of the neighbor who turns the water on and off. In the dairy a small electric motor of about 3 horsepower, actuated by the electric current, drives the cream separator and also furnishes power for running the grindstone, feed cutters, hay fork and fanning mill, in addition to which the power is also used to milk the cows and cut the ensilage and to do numerous other bits of work about the place. Mr. Van Wagenen states that his water power does work equivalent to that of a hired man the year round and does away with numerous chores and laborious duties about the place. The arrangement which Mr. Van Wagenen devised to turn on the water at his plant and to shut it off again is unique and interesting. It consists of a triangular frame lever about two feet wide and seven feet high, hinged at one of the bottom corners. The other bottom corner is connected to a sliding gate which fits over the feed pipe for the waterwheel. At the top are fastened two wires, one of which runs to the house of Mr. Van Wagenen’s accommodating neighbor, and the other runs over a pulley and has a counterweight attached to it. When the water is to be turned on, the neighbor pulls the wire and the gate is raised by the leverage of the frame; when the water is to be shut off, he releases the wire and the counterweight pulls the lever back, allowing the gate to fall in place again.
