Mr. Miner realized that there would be times when he would not require all or any of the power which would be produced. At the same time the pond formed by the dam was not large enough to store any considerable amount of water, and he had all the power he would require at any one time, so it was not considered necessary to provide storage batteries to store the electricity. On the other hand he did not wish to be compelled to turn the water on and off at frequent intervals, as would be necessary unless some auxiliary regulating apparatus were provided. Therefore, it was decided to provide for the plant to run continuously and to devise some means to consume the electric current when not in use. A series of resistance coils were mounted on a frame in the power house, and connected with the generator. When the demand for electric current is less than the capacity of the generator, a small electric device automatically throws one or more of these coils into the circuit, and the surplus current is converted into heat by the resistance of the coils. By means of this arrangement it was planned to run the plant continuously, so that whenever electric current was wanted it could be had simply by turning a switch at the house or barns. The power plant, including the dam and all the features thus far described, was completed and in operation before Christmas of the year in which the construction was begun. We have thus far seen how Mr. Miner developed his water power and transformed it into electricity. It remains to see how he gets it to his house and farm buildings, and how he uses it after he gets it there. The power house is situated about 1700 feet from the house, where the electric current was most wanted. This necessitated the construction of a transmission line. For this purpose a double line of bare aluminum wire was stretched on a row of poles about twenty feet high and about one hundred feet apart. The poles are provided with ordinary crossarms at the top on which are mounted the insulators carrying the wires. As the transmission line leaves the power house it crosses a highway and runs in a perfectly straight line to the house. Over the highway insulated wires were used as a safety precaution, but bare aluminum wire was used for the remainder because it was cheaper. The buildings are all in a cluster and a branch from the transmission line runs into each one where the current is used. All the wires which are inside of any of the buildings, or are close to the woodwork, are covered with insulation, and, where concealed, are further protected by being placed in twisted metal tubes. The first actual use of this hydro-electric power was for lighting. The house was illuminated with electric lights, as were also the barn and other buildings, there being ultimately about seventy 16-candle-power lamps in use. Even the pig sty has its electric light, and there is no more groping in the dark anywhere about the Miner farm buildings.
