Near the village of Berlin, in eastern Rensselaer county, N. Y., there is a small power development owned by Mr. Arthur Cowee. His source of power is a small trout brook which flows through the farm. Mr. Cowee is a producer of fancy gladiolus bulbs, on a large scale. His principal power development, consisting of a 36-inch impulse waterwheel, under a pressure due to a fall of about 210 feet, is used mostly for the purpose of operating a circular saw and other machinery connected with a sawmill. The water is diverted from the natural channel of the brook at a considerable distance from the place where the waterwheel is installed and is carried in an artificial channel, about four feet wide and three feet deep, around the side of the hill, where it runs into a shallow basin which has been excavated by Mr. Cowee at a suitable location. By means of this basin, or artificial pond, practically all of the flow of the brook may be stored during the night and used to operate the waterwheel during the day. In this manner the full power value of the brook is realized. There is a ten-inch, cast-iron pipe line, about 1680 feet long, which runs from the pond down the side of the hill to the waterwheel. This pipe line was placed under ground from three to four feet in order to avoid freezing in the winter. Mr. Cowee estimates that the development, including the diverting dam and canal, pond, pipe line, waterwheel, circular saw and accessories, cost him a total of about $7000. He states that he can saw about 4000 feet of lumber in a day with this power. In addition to this development, Mr. Cowee also has a small impulse waterwheel in his bulb house. This wheel is operated by water furnished from the system of the local water company. It is directly connected to a small electric generator which furnishes electricity sufficient for 157 sixteen-candle-power carbon-filament lamps which are installed throughout the bulb house. The generator does not produce enough electric current to run all of these lights at the same time, but it will operate as many as forty-five or fifty lights at one time, which is all that is necessary to meet the requirements. Mr. D. F. Paine of Wadhams, Essex county, N. Y., has a dam at the outlet of Lincoln pond. The water surface, when the pond is full, is about twelve feet above the normal and spreads over an extensive tract of low, marshy land. The pond thus formed is about three miles long and from one-quarter to three-quarters of a mile wide. The water is conducted from the dam to the penstock, a distance of about a mile and a half, securing a fall of 320 feet. At this point Mr. Paine has constructed a power house, where he generates electricity which he transmits to Mineville for use in the mines. This power is transmitted a distance of about eight miles.
