BUSINESS.

The Brodie Electric company of Manchester, N. H., has just placed upon the market a special tree insulator, adapted to carry heavy wires and cables up to No. 0000. It is the same general form as the well-known insulator which this company has for some time been furnishing to the trade, making use of a porcelain pulley to carry the conductor and a malleable iron lag-screw for attachment to the tree. These insulators are furnished with either single or double petticoats, and are especially intended for use on street railway and other heavy feeders which demand a high degree of insulation.
