There are two Reynolds-Corliss 2,000-h. p.cross-compound, horizontal, condensing engines with cylinders 32 pumps and boilers in the order named. All water of condensa-tion except that from the condensers is returned to the boilers. Two oil pumps for filling the gravity tanks, an air compressor,blower, motors and shafting for the pumps and economizers com-plete the outfit of the engine room. A feature worthy of noteIs that one motor with countershaft furnishes power for (hesix geared pumps, the blower, air compressor and two sets ofeconomizer tube scrapers cleaning 2,080 tubes. All the electrical controlling apparatus is grouped at the frontend of the station on a gallery commanding a view of the wholeengine room.

and 62x60-in. stroke with 24-ft. fly-wheels making 75 r. p. m.;also independent circulating pump and jet condenser of the verti-cal pattern. The latter two engines have feed water heaters,Stratton separators, built by the Goubert Manufacturing Company, and independent steam connections to each side so thateither side can be operated under high pressure with the otherdisconnected. All engines have practically indestructible plate fly-wheelsweighing 60 to 70 tons. All have intermediate re-heating re-ceivers, free exhaust, and circulating condensing water connec-tions. The latter is taken from South Bay by 36-in. cast ironpipes having the necessary fish traps, check valves and screens,and connections are made direct with all condensers. The feed water is handled by a series of six electrically-oper-ated gang pumps of the four-pluuger pattern, piped to heaters,economizers and boilers and connected with city water pipes bythe usual methods.
