A St. Petersburg dispatch states that the admiralty has installedSiemens & Halske wireless telegraph apparatus on five battleshipsand the cruisers Aurora and Dmitri Donskoi. All of the ships thatare being fitted out on the Baltic Sea are, it is stated, also beingequipped in a similar manner. The Russians appear to have changed. Fig. II.—View of Interior of Bear River Power He brought through a 24-in. pipe directly from the large syphon 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
