The first6 ft. of the engine room walls are of white enamelled brick,with dado above, and the remaining wall is to be treatedwith cold water paint. The chief engineers offices are located at one end of theroom, and so arranged that visitors to the station will enteronly through a door leading into the basement and by astaircase leading into these offices. The entire system of steam and water piping has beendeveloped with the greatest care for the service required inthe operation of the station. Extra heavy valves and fittings. PLAN OF POWER STATION work, consisting of a 4-pole, 50-kw, 750 r. p. m., 125-voitdirect-current generator, direct-connected to and mountedon a common base, with a 4-pole, 75-hp, 750 r. p. 350-volt form K induction motor. A traveling crane of 25 tons rated capacity sweeps theentire engine room floor, resting on a steel track, supporteddirectly, upon steel columns, which pass vertically to thebasement floor level. This crane was furnished by theWhiting Foundry & Machine Company, of Harvey, 111. Itwas necessary to excavate to a depth of 12 ft. below thebasement floor level in order to provide suitable founda-tions for the building and its heavy machinery. Thefoundations were all built of Portland cement concrete. The frame of the building is especially heavy in steel, allroof trusses and the frame of the engine room floor beingof steel construction. About 150 tons were used in thiswork, furnished by the American Bridge Company. Brick are used where live
