s roomcontains practically all steam, exhaust and water piping forthe entire plant. It is arranged for easy access to allvalves and other parts by means of steel runways. ducts in the basement, which connect with a protected open-ing to the exterior of the building. The turbo-generators, which are of the Westinghouse-Parsons type, are of interest, due to certain features ofdesign, which are along very modern lines. Each unit hasa capacity of 500 kilowatts, delivering three-phase, sixtycycle current at 480 volts. Generators are of the revolvingfield type, speed being 3,600 revolutions per minute. In thistype of apparatus the energy is derived by allowing steamto expand from high pressure and temperature to lowpressure and temperature through a series of alternatelymoving and stationay blades, or vanes, termed respectivelythe rotor and stator. The rotor vanes are carried on aseries of drums of different diameters mounted on steelshaft. Stator. or stationary blades, are placed inside the
