After being usedthe oil is filtered and two pumps return it to the tank. The switchboard is of white marble and is unusually compactfor so large a station. The four panels to the left are each for agenerator. Each panel has a General Electric circuit breaker andswitches, a 2,500-amperc Weston ammeter and field rheostat con-troller, the resistance of which is under the floor. The next panelto the right receives the entire current of the station and is de-signed to carry amperes. It has a 750-voIt voltmeter and an8,000-ampere ammeter, a General Electric wattmeter, and a Bristolrecording voltmeter. The next panel supplies current to the sta-tion.

The power house is located at 40th and State Sts., on the line ofthe Lake Shore & Michigan Southern, and was designed by & Lundy, consulting engineers for the company. The building is 200 ft. and divided lengthwise into largerooms; the engine room is 59 ft., and the boiler rootn 48 ft. engine equipment comprises four cross compound, con-densing AUis-Corliss engines with cylinders 26 and 54 -x 48 in.; speed80 r. p. m. Each engine will develop normally 1,200 h. p., but willcarry a 66 per cent overload. The direct connected Westinghousegenerators are of 8oo-kw. capacity, giving 1,280 anipers at 625 volts,although the generators are capable of running under temporaryoverloads of 100 per cent.
