MISCELLANEOUS.

The Security Insulator company of New York has made some large shipments of its well known insulators to Australia. This company supplied the insulators used in the wiring for electric lights for both the new railroad depots at Elizabeth, N. J. An important change has been made in the insulators now being placed on the market. The screw hole has been widened from 3/8 of an inch to 1/4 an inch. The Electric Appliance company of Chicago and the Enterprise Electric & Construction company of New Orleans are both working up a large trade for these insulators.
