In order that there should be no excessive loss indistribution, these concentrated steam power unitsare usually found in the heart of the great distributioncenters. Especially is this true where abundance ofcirculating or cooling water may be obtained. Thuswe find in central California, Station A and Station Cof the Pacific Gas & Electric Company, and the Fruit-vale station of the Southern Pacific Company all sit-uated in the distributing centers of San Francisco andits immediate vicinity. In Los Angeles we find thatthe Redondo plant of the Pacific Light & Power Cor-poration and the Long Beach plant of the SouthernCalifornia Edison Company, owing to the lack of. »«• «••*, Interior of a Modern Horizontal Steam Turbine-Driven Electric Power Plant.

General Description of the Modern Power Plant. It will now be interesting and instructive to ex-amine the details of a typical power installation of thesort just hinted at. First, we shall describe the so-called steam cycle,or the journey of the steam making water from thetime it enters the steam boiler until it has completedits journey through the turbine, or power unit, andreturned again to the boiler; secondly, we shall con-sider the circulating water which is necessary in largequantities to convert the exhaust steam back againinto water; and thirdly, we shall touch briefly uponthe journey of the oil from the time it leaves the carsat the sidetrack until it disappears from the chim
