The water is then conducted by aflume, provided with sand-boxes and settling basins, to a pipe line3,300 feet in length. The latter has a total fall of 1,325 feet, and variesin diameter from 24 inches at the upper end to 19 inches near thewater wheels. It is firmly anchored to the rocks and is provided withsix air valves. The regulation of the wheels is accomplished by theuse of deflecting hoods.

The latter run at aspeed of 515 revolutions per minute and generate three-phase currentsat 440 volts and 60 cycles. A cast steel fly wheel weighing 4,000pounds is mounted on one end of the dynamo shaft,and the water wheel,which is carried by the other end of the same shaft, weighs 2,000pounds. The voltage is raised from 440 to volts in three oil- THE ENGINEERING THE PIPE LINE OF THE MT. WHITNEY POWER CO., is a view looking down from the penstock along the pipe line to the power house. insulated, self-cooling transformers of 500 KW. capacity each, withone spare. The transformers can be arranged in star connection togive 34,600 volts. There are sub-stations at Visalia, Tulare, Porterville, Exeter andLindsay, where the distribution is at 2,000 volts. A novel feature ofthe power distribution in this plant is the fact that interrupters areused on the lighting circuits. Current for lighting is sold to the con-sumer at flat rates and the interrupter causes the light to flicker when ELECTRIC POWER TRANSMISSION. 8S
