It is about 60 ft. long, 30 ft. wide and 43 ft. 6 above the floor line. It is amply lighted by three rows ofwindows, the larger ones being 7 ft. i in. high, 2 ft. 6 ins. wide,and the smaller 3 ft. high by 2 ft. 6 ins. wide. There are twenty-seven large windows and twelve small ones. The roof is flat,and in five-ply tar and gravel, and is surrounded by a galvanizediron coping. The second floor is 17 ft. above the first.

The battery and booster switchboard is located near thebooster, and is composed of two panels, with the usual com-plement of switches and instruments. The coal supply of thestation is, in the main, obtained from the companys mine atRenton, and condensing water is obtained from the Seattleharbor through a long suction pipe. 12 ft. high and 8 ft. wide, serves as admission for heavy ap-paratus to the transformer room.
