The main wires pass straight out through the wallat a point just under the roof, and then pass to the pole linesthrough the medium of special strain-insulator anchoragessimilar to those which have been described in connection withthe sub-station designs. Within the terminal house there are. Slreel Rj. Journal TERMINAL HOUSE Street Ily. Journal WIRING, FALL RIVER TERMINAL HOUSE receive the bolt heads. The arms are braced by 2-in. x 2-in. xYn-in. angle-iron braces, fastened to the pole by two J^-in. x4-in. lag screws, and to the under side of the arms by doubleYz-m. bolts. On angle construction heavier poles are put in,and the angle poles have double cross-arms thoroughly braced. Inasmuch as it was necessary to run the transmission linesthrough several municipalities, it was thought best to carrythe high-tension cables underground through thickly populateddistricts. At each point where the line enters or leaves theunderground conduits there has been erected a terminal housein which are located disconnecting switches, lightning arrest-ers, etc. The design of these houses will be understood fromthe drawings of the Fall River house, which is typical of theothers. The house consists of a brick building 15 ft. x 11 16 ft. high, resting on s
