The glass insulator shown in the accompanying illustration, which is being placed on the market by the Brookfield Glass Company, 2 Rector Street, New York, was first designed for the Pacific States Telephone & Telegraph Company's mountain lines. Two right-angled grooves are provided on the top of the insulator. In the groove parallel to the line the line wire is placed. A fastening wire is passed over this wire in the other groove and is tied around the insulator in the groove provided below.
This insulator by reason of its design is especially well adapted for use on lines which are installed in hilly districts of the country.
