The three substations located at .Ashcville, Canal Winchester andHooker are all similar, being designed to receive two 400-kw. rotaryconverters, only one being installed in each at this sub-station buildings, like the power station, are of fireproof to isolate the oil switches and also the static interrupters, readyaccess to these switches being had by means of a gallery over the oilswitches. The bus bars and high tension leads are supported oninsulators mounted on iron pins which are carried on pipe brackets. Sept. 20. 1904.] STREET RAILWAY RENIEW. 567 Electric Line Construction. The high tension line from the power station to the sub-stationsis substantially built. The poles are 40 ft. long with tops 7 in. indiameter, and are spaced 100 ft. apart. Two cross-arms are mountedon each pole, the top cross arm being 4^^x5^Sx70 in. long designedfor two pins and insulators. The lower cross arm is 4^^<x5^<.\ioo and has space for four p
