r), extending northerly and westerly to near theouter end of the line; another tapped on by 638,000 circ.mil aluminum cables (equivalent to 400,000 circ. mil CO)per) to trolley wire opposite substation, and another p/irof 1,192,500 circ. mil aluminum cables extending sooth.Feeder taps are located from 1000 ft. to 2270 ft. ilpart,with section breaks between them. With this arrange-ment of feeders, with ten cars in operatio/f on thedivision and 600 volts emf at Aloha Stree^it is esti-mated that the maximum drop would be experienced atthe outer end of the line, being about 61JB volts or 10.3per cent at the furthest feeder tap. N^r the southerlyend the drop is less. On the initial yfetallation, a sav-ing in first cost of more than SS.OOflivas made by usingaluminum instead of copper, the price per pound ofaluminum cable being 22.3 cents delivered at Seattle,while copper cable was 15.6 cents per pound, the totalweight of aluminum required being of course very muchless for equal conducffqnci

$3,000Saved by installing ALUMINUMCONDUCTORS That saving, too, takes into account only thesaving in first cost of aluminum over the costof copper. The saving by reduction of numberof poles, with pins, insulators, etc., possiblethrough the use of longer spans practicable be-cause of the light weight of aluminum, largelyswells the above figure. Reduced maintenancecharges is a vastly important item ; dont forgetthat Aluminum is advancing as the ideal metalfor feeders and transmission lines. It is advanc-ing because it pays. Make it pay you.
