The polesare set 6 ft. deep in the ground, but not concreted except inspecial cases where the soil is loose or soft. The distance be-tween the center line of track and the poles is 7 ft. The transmission line cross-arms are of yellow pine, the gutters, made by the F. M. Locke Company. The outer petti-coat 7 ins. in diameter. The lower wires are supported half-way between the upper and lower arms. Along the tops of the poles is carried a ground wire of No. 6galvanized B.
