The turbines are controlled by oil governors, anda special Tirrel regulator is provided to operate theexciters of each generator when they are working onthe same transmission system. Transmission The transmission line passes from the east sideof the river across the river and up the rim of thewestern mountain, a climb of 3500 feet over the mostrugged country. In nearly an air line it is then car-ried to a switching station at Joland Junction on theSanta Fe, Prescott and Phoenix Railroad, a distanceof 35 miles. Considerable trouble was experienced from light-ning on the line over the Verde River, at the com-mencement of opeiations, and a supplementary lineon wooden towers was constructed up the Verde val-. Concrete pipe, connecting pressure tunnel to pressure pipe at plant head,under about 17 ft. head ley 51 miles to Clarkdale, the site of the UnitedVerde Copper Companys new smelter, and thence tothe Jerome sub-station. Each property is thereforeable to secure power from two directions. From sub-stations at Jerome and Clarkdale allof the various mines and prospects in the Jerome dis-trict are reached by taps from the main line or by2300-volt distiibuting circuits. In March, 1918, the transmission lines ownedand operated were as follows: Main Tower Lines 45,000 volts, 180 miles Distributing Line 17,000 volts, 27 miles Distributing Line 11,000 volts, 34 miles Distributing Line 2,300 volts, 20 miles Total of three-wire lines, 261 milesor over 800 miles of copper transmission wire andsteel groundwire. It is an interesting fact that practically all ofthe copper wire was purchased from the UnitedVerde Companys wire drawing plant at Perth Am-boy, N. J., and it has th
