Electrical news and engineering . in all. These piles, driven to hard|)nn, average about 18 feet in length and are capped withe-in. X 8-in. cedar timber. A special foot was designed tomeet the condition and the towers liolted direct to thetimber. The Pitt River, a navigable stream, is crossed hereon a span 1360 ft. in length, and as it was necessary to pro-vide at least 100 ft. at the lowest point of the span aspecial construction was resorted to. A galvanized steeltower, 165 ft. over all in height, and 140 ft. from groundto low wire was placed on a concrete and pile foundationjust outside the dyke on each bank of the river. A rockertower, set to give an angle to the main line, of about 45degrees is the starting point of the line wires. This rockertower is securely anchored by one-inch steel cables to aconcrete and pile anchor. The main span is dead endeclat the rocker tower on each side and is free to movelongitudinally on the supports of the main tower, so thatthese act simply as struts to afford height and have no.
