This is accomplished by running thefeeders through a feeder pillar containing the necessaryswitches and fuses, the connections from the feeders to thetrolley wires being made with rubber-covered cables, car- ried up inside the poles and along the sides of the bracketarms. The pressure on the trolley wire is 500 volts. A light-ning arrester is provided in each feeder pillar, and also a tele-phone giving direct communication with the power house. Thefeeder cables were supplied by the Callenders Cable & Con-struction Company and laid on the solid system. In additionto the main feeders running east and west from the power sta-tion, a return booster feeder has been laid in each direction towithin a mile of the two distant termini, where it is connectedto the rails; it also makes c
