The fourth main is to Oernon, and, after a course of has a branch of miles to Moiran, both circuits beingof three 4-mm. wires. The total length of the high-tension circuits is miles. Thewires are mostly carried on 33-ft. poles, of which there are 3, FIG. 6.—DETAILS OF 7OO-HP GENERATOR. These poles are in straight stretches ft. apart, while in curves82 ft. is the usual distance. The greatest distance apart in any placeis 246 ft. All poles are saturated either with copper sulphate or zincchloride. They are fitted on top with pointed cast-iron caps or pro-
