Afterleaving the high-tension side of its transformers, each wire of thethree-phase circuit passes, without lateral deviation, successivelyto a static interrupter, a high-tension switch of special design, a low-equivalent lighting arrester, and finally out of the window througha long glass bushing. This window consists of two sheets of heavyplate glass six inches apart, with holes in the centers for support ofthe bushing. All electrical apparatus in the power house is ofWestinghouse manufacture. The transmission features of the plantwill be considered in a concluding article. Wireless Telegraphy on Russian Ships.

Fig. II.—View of Interior of Bear River Power He brought through a 24-in. pipe directly from the large syphon pipe.This pipe branches outside the building into two l8-in. pipes, whichsupply the turbines. The exciters are thus driven independentlyof the large generators, and better regulation and greater reliabiilityare, therefore, afforded. Figs. 10 and II are views of the interiorof the power house, showing the large units and switchboard. The discharge water from the turbines is carried by means of fourdraft tubes, each leading down with a long 90-degree vertical bend,to a flaring concrete tunnel under the power house i^oor. Thesetunnels all terminate in a common tail race and are so proportionedthat the water is brought almost to rest before being discharged, sothat as much as possible of its energy is utilized. The draft tubesof the exciter turbines discharge into the two inside tunnels. The nine-panel marble switchboard which receives the 2,300-voltcurrent from the generators h
