ordinary driven wood pin, rather tends to preserve it. These pins will withstand a strain of 1,800 pounds, while oak and locust pins break at 700 and 900 pounds respectively. The triple petticoat insulator shown, as well as the pin, is manufactured by Fred M. Locke & Co., Victor, N. Y. and is especially suited where high insulation is necessary, as it has been largely used upon high tension lines, up to 10,000 volts, and another style is made, which, it is claimed, can be used with voltages up to 35,000.
