At Chazy, N. Y., near the western shore of Lake Champlain and at a point about fifteen miles north of the city of Plattsburg, there is located a modern stock and dairy farm which, in its operation, exemplifies the manifold advantages to be derived from the use of hydro-electric power for electric lighting and for the various power requirements of the farm. This farm, which is owned by Mr. W. H. Miner and is called “Heart’s Delight,” covers an area of 5160 acres. About 1200 acres are cultivated, 1200 acres are in pasture and the remainder in woodland. The output consists of live stock and dairy products, all crops grown on the farm being fed to the stock and only finished products being shipped out. The live stock includes registered Percheron and Belgian horses, pure-bred, short-horn Durham and Guernsey cattle, Dorset sheep and high-grade hogs for the production of sausage, hams and bacon. There are also poultry and squabs, and a fish hatchery for the propagation of trout. The entire output goes directly to high-grade hotels in New York, Washington and Chicago. [Illustration: Power House, “Heart’s Delight” Farm] Two streams pass through the southern portion of the farm, the smaller one being known as Tracy brook and the larger one as Chazy river. It was decided to provide the farm with electricity for light and power. Enough water power was found in these streams to furnish a cheap and reliable source of energy. Accordingly, a hydro-electric plant was installed several years ago and has given such satisfaction that the equipment has been increased from time to time, and some novel applications have resulted. Three small concrete dams were built across Tracy brook to form storage reservoirs. A concrete penstock, or pipe, 44 inches in diameter and 670 feet long, carries the water from the downstream reservoir to a concrete power house, where a fall of 19 feet is secured. [Illustration: Alternating Current Transmission Line, “Heart’s Delight” Farm] The power house equipment consists of two water turbines automatically governed and directly connected respectively to one 30-kilowatt and one 12½-kilowatt, 220-volt, direct current generators. The current is transmitted over a pole line, a mile and a quarter long, to a central station in the main group of farm buildings.

This is of concrete, and, after passing through screens at the intake gate house, built into the dam, the water flows through a concrete penstock, 48 inches wide by 60 inches high and 630 feet long, to the power house where a fall of 30 feet is obtained. There are two turbines here, belt connected to alternating current generators, and the current is transmitted over a pole line, nearly three miles long, to the central station.
