OF P A P E R The paper is devoted chiefly to a historical sketch of the West Penn system in regard to its electrical service in connection with coal mines. T h e first mine installation was connected to the system in 1896 and pre vious to t h a t time it had been found very difficult to convince the mine operators of the advisability of central station service, as they claimed t h a t it was not as reliable as an isolated plant. The central station service was also antagonized by the mine

These objections were only overcome after several years of successful operation iij a large number of mines. T h e paper mentions a number of mine installations which have been supplied by the central station company's power and describes various difficulties t h a t have arisen in regard to such installations and the methods of overcoming them. The growth of this business is shown by the fact t h a t since the original installation of 120 horse power in one mine, the company now supplies power for 76 coal mines aggregating nearly 15,000 horse power, and has contracts with 10 companies for over 5000 horse power to be installed as soon as possible. 990
