To handle the service on these lines the company installed a system of electric generation and distribution conforming tothe latest American practice. The generating station, shownin two of the accompanying views, contains three 1200-kwunits, each consisting of a 28-pole, 6600-volt, 25-cycle, direct-connected, three-phase generator driven at 107 r. p. m. by ahorizontal cross-compound engine. These engines were builtby Mcintosh & Seymour, of Auburn, N. Y., and have cylinders30 ins. and 62 ins. x 42 ins., designed for 140 lbs. initial pres-sure. Two of these units are normally in use, the third being. ROTARY CONVERTERS AND SWITCHBOARD IN THE IMAGA-WABASHI SUB-STATION held in reserve. The excitation is furnished by two MP 6-pole,100-kw, 125-volt generators direct driven at 225 r. p. m. byMcintosh & Seymour tandenvcompound 9^-in. and 19-in. x15-in. engines, either unit being of sufficient size to excite allthree alternators, with a liberal margin besides for the supplyof station lighting. The engine room is served by a 20-ton, 50-ft. span, three-motor Morgan crane, equipped with General Electric motorsand controllers. Jet condensers and air pumps of the Blake-Knowles SteamPump Works make are used for the main and exciter equipment of the boiler room consists of four batteries ofBabcock & Wilcox boilers, each comprising two 350-hp boilersgenerating steam at 150 lbs. The ordinary feed-pumps are induplicate, and are further supplemented by a small automaticpump, which, acting in connection with a receiver, delivers tothe boiler feed system the water of condensation d
