All the feed wires inside of the citylimits have been placed under ground in the shape of 1, 000, 000-circ. mil, paper-insulated, lead-covered cables. Outside ofthe city limits considerable aluminum overhead feed wire has. Street Railway J<n DIAGRAM SHOWING COMPLICATED CONSTRUCTION, CORNERILLINOIS AND WASHINGTON STREETS, INDIANAPOLIS been employed. Although large in section, the aluminum feed-ers weigh less for a given conductivity than copper feeders, andconsequently put less strain on a pole Line which carries agiven amount of current. The conduit into which the under-ground feeders are placed is Camp single-duct vitrified tile.Poles for straight line work in the city are two-section steeltubular poles, 8 ins. and 7 ins. in diameter, weighing approxi-mately 850 lbs. each. They are 28 ft. long. The poles are setin concrete. It will be seen from these specifications that the overheadwork in Milwaukee in general is somewhat heavier than pre-vails in other cities. The most radical change from ordinaryline work adopted in Milwaukee, however, is the abolitionof insulating trolley wire hangers. The trolley wire hangersare entirely of metal. The insulation is all obtained by straininsulators in the span wi
