Six horsepower will run a feed mill grinding twenty bushels of corn an hour. Five horsepower grinds twenty-five to forty bushels of feed, or ten to twelve bushels of ear corn, an hour. Seven horsepower drives an eighteen-inch separator, burr mill and corn and cob crusher and corn sheller, grinding from twelve to fifteen bushels of feed an hour, and five to eight bushels of good, fine meal. Six horsepower runs a heavy apple grater, grinding and pressing 200 to 250 bushels of apples an hour. Five horsepower will drive a thirty-inch circular saw, sawing from fifty to seventy-five cords of stovewood from hard oak in ten hours. [Illustration: Electric Ironing] Six horsepower saws all the wood four men can pile in cords. Twelve horsepower will drive a fifty-inch circular saw, sawing 4000 feet of oak, or 5000 feet of poplar, in a day. Ten horsepower will run a sixteen-inch ensilage cutter and blower, and elevate the ensilage into a silo thirty feet high at the rate of seven tons per hour. One horsepower will pump water from a well of ordinary depth in sufficient quantity to supply an ordinary farmhouse and all the buildings with water for all the ordinary uses. In determining the size of power plant required in any particular instance the use requiring the largest amount of power must be considered. It follows that there will then be plenty of power for the smaller requirements. In considering a water power it should also be borne in mind that the full theoretical amount of a water power can never be realized, a certain portion being taken up in friction in the waterwheel and in losses in the electric generator, transmission lines, motors, etc. The question as to how much may be made available will be discussed hereinafter. Following are descriptions of some typical water-power developments in use in this State at the present time. FARM WATER-POWER DEVELOPMENT IN ONEIDA COUNTY [Illustration: Electric Hot Plate] On the outskirts of the village of Oriskany Falls, in Oneida county, N. Y., is a farm of about 100 acres, belonging to Mr. E. Burdette Miner. This community was at one time one of the principal hop-raising districts of the State. Mr. Miner has been engaged in raising hops for fifty years, and raised 10,000 pounds of hops on seven acres the past season. In recent years he has divided his attention between mixed farming and dairying, keeping from twenty to twenty-five cows.
