nd of the galleries. In thebasement between the foundations of the two rows of gener-ating units are the condenser pumps and other auxiliary ma-chinery for the generating units. The high-tension buses,distant-control electrically operated oil switches and otherhigh-tension apparatus are installed in the basement in anisolated compartment partly under the south end of the gal- forced draft. Those boilers in the older portion of the planthave 6500 sq. ft. of heating surface, while the remainingeight are somewhat larger, having 7000 sq. ft. No econo-mizers are installed, but the boilers are provided with super-heaters consisting of five rows of 4-in. tubes which giveabout 60 degrees of superheat to the steam. The boilers areoperated at 160 lbs. pressure. The boiler steam gages, as wellas all of the other steam and vacuum gages in the plant, aregraduated from zero pressure absolute. This was done toeliminate the necessity of reducing pressures above the atmos- ;g^%i^%^.s:-^%^^:y^ii^^%^^^^

In the basement arealso toilet rooms which contain shower baths and lockers andare finished in Tennessee marble. BOILER PLANTThe boiler plant consists of eight units, each made up oftwo Edgemoor boilers equipped with a stack and auxiliaryapparatus independent of the other units and piped separatelyto one of the eight large generating units in the operatingroom. Each boiler is equipped with a Monitor injector, fourJones underfeed stokers, a Squires feed water regulator, anda motor-driven centrifugal fan for supplying pressure for phere to absolute pressures in working up indicator cards, aswell as to avoid the necessity of referring to vacuum inspeaking of condenser pressures. The space immediatelyabove the boilers and on each side of the coal bunkers hasbeen reserved for economizers, but with coal at its presentprice it has not been deemed advisable to install them.
