The cost of another branch line, capable of transmitting 
50 hp. over 13 miles at 2,400 volts, was £162. 25 ft. poles 
costing 11s. each were used, 2,264 tbs No.6 B. & S. gal- 
vanized iron Wire, and double petticoat glass insulators 
costing 23d. each. Labour cost the same as above. The 
country traversed was rocky, and holes were not easily 
sunk. The Hlectricity Supply Company put down wells, 
the depth from which water is pumped ranges from 150 
to 175 feet. The efficiency of the pumping plants, water 
Hp. to H.H.P., is just greater than 40%, Byron Jackson 
pumps being used. 
The representative of the G.K. Company in Los Angeles 
kindly furnished the following information, concerning the 
electric transmission and pumping plants in the neighbour-

The Edison EK. Co., whose transmission line runs from 
Santa Ana Canyon to Los Angeles, a distance of 88 miles,

Pasadena, Dolgeville, Wheltier, Fullerton, Santa Ana, 
Orange and Anaheim, from all of which branch lines are 
run to the various ranches, orange, lemon and walnut

are used for pumping water.
