company set about bridling the stream which rushed out of the San Gabriel canon creating enormous power that had never been utilized. More than $500, 600 was expended in the enterprise and electrical engineers from all over the world watched the progress of the work. In half a dozen ways the utiliza- tion of the power in San Gabriel canon stream and then the turning of the wa ter back into the original course for ir- rigatiOn by the orange and lemon grow CTS in the valley below were without precedent. By eight miles of tunnels and cement ditches a fall of 400 feet was created in the canon stream. 4 power house was built among the rocks and in it were set up eight powerful Tuthill wheels (built in four pieces) on mammoth steel shaft. Each wheel is forty-eight inches in diameter. and each pair of wheels delivers $50 horse power to a dynamo through a special flexible coupling with a governor de- signed especially for this high duty Thew heels are of the jet on tangental type. They are supplied from nozzles having a diameter of 3 Is inches and each gate is provided with a special valve so that each one can be used in- dependently when desired. This is the largest jet-wheel plant west of Niagara Falls
 The San Gabriel company has been sending 5000 horse power to Los An geles, distance of twenty-seven miles There the power is used for lighting, running street cars. raising elevators and light machinery.
 During the last sixty days the most remarkable piece of electrical engineer ] ing in the country has been finished af- ter three years of labor and some $600,- 900 had been spent in the enterprise. 1 The Santa Ana River, which comes out 1 of the San Bernardino mountains, has been bridled, and it's power is now 1 transmitted to Los Angeles-some eighty-two miles distant. Thus 5000 horse power is made to propel machin- i cry, move street cars, and illuminate and even heat buildings in Los An geles, besides furnishing illumination and power for several villages-such as Redlands, Riverside, Colton and On- tario-between the mountains and Los Angeles.
 The many engineers out here from New York and Chicago agree that the most remarkable feature in the de- velopment of the power on the Santa Ana River is the transmission of elec- tricity of high voltage over eighty miles of wire with so little loss of en- ergy. The company finds it can now send electricity of 33,000 volts, having a 1 working efficiency of 4,00O horse power, distance of eightythree miles, with a loss of but 10 per cent. In 1890, when a current of only 5000 volts was sent through the Lauffen-Frankfort circuit in Switzerland for experimental pur- poses, and there was loss of only II per cent, this was proclaimed as a feat.
 1 After doing its work in the produc- tion of electrical energy the mountain stream is gathered into an enormous conduit and led down the mountain side to irrigate the orchards and groves ir the San Berardino Valley.
 The power station in Santa Ana canon is a small stone building. In it is some of the finest electrical machinery yet made. The water is taken from the river through a canal, Hume and tun' mel along the side of the canon, where it is led into 6 pipe 2,200 feet long. giv' ing what is equivalent to a vertical fal of 750 feet. The wheels are of the i'm pact type. directly connected with tho generators, of which there are four each of 1000 horse power capacity. The maximum line potential is S3,000 volts to which potential the initial voltage will be raised by 250 kllowatt step-ur transformers. The generators are of ar improved three phrase type. revolving field. external armature, and each has a capability of 1.000 horse power, anC generates electricity at 750 volts. Thi: is conveyed to transformers, of whicf there are twelve. The current of cleo tricity enters at T50 volts and comes ou at S3,000 volts on a line of wire whicr has no connection with any dynamo.
 The San Joaquin Electric company which has recently finished harnessins a stream in the Sierras and is now transmitting several thousand horse power over IOOlulltS, dCFDSS flNeFS ranches and vineyards to Fresno anC adjacent towns. has also accomplished wonders in this field of science and in vention Power is furnished there a cheaply as two cents per horse powe
 per hour.
