Except in towns where standard overhead trolley con-struction is necessary, and here the Brown pantagraph trolley side walls are covered with a cement plaster supported onmetal lath. The gable ends have metal lath on both sidesand are covered with cement mortar, thus forming a doublewall. The roof structure is supported on a timli with iron rods as tension members. The weather surface comprises Xo. 24 corrugated galvanized iron, laid with 10 incheslap. Inside the building the roof is ceiled with No. 28 paintedcorrugated iron. Accompanying illustrations willshow the interior arrangement of the structure and the dis-position of the apparatus. The equipment for each standard substation c;mpr:i.

The third rail is bonded at the joints with two250,000-circular-mil Chase-Shawmut soldered bonds. At roadcrossings the ends of the third rail on opposite sides of thehighway are connected with a copper conductor of 500,000-circular-mils cross section inclosed in a bituminized fiber con-duit and buried. The ends of this conduit are filled withinsulating compound to keep out water. One of the accom-panying illustrations shows the general arrangement of trackand third rails at a switch. It will be noted that a variationfrom the usual practice occurs in the omission of the droprail opposite the switchpoint. Substations. Current for the operation of the entire line is purchasedfrom the Pacific Gas & Electric Corporation, being deliveredto the substations at 60,000 volts po
