. Electrical world. e taken placeon Wednesday afternoon at 3.30, when the United Company expectedto turn current on to the new underground, three-wire, direct-currentsystem. Fig. 4 shows the new McClellan Street station, which had amost fortunate escape, the only damage being the breakage of thewindows through the falling of neighboring walls.
