It consists of twounits, one on the east and one on the west side of the sta-tion. Each unit consists of two artesian wells, from which water pumped by a Deane triplex double-acting pumpthrough a cooler consisting of a bank of piping situated onthe unused local platform upon each side. The pump isdriven by one C. & C. 40-horsepower direct-current motor,running on a 625-volt circuit. The banlv of piping is en-closed in a galvanized iron casing, which has an inlet atone end, connected to the discharge of two fans installed bythe American Blower Company, New York, which deliver.

Theblowers take air directly from the inside of the station andare driven by a motor similar to that used for the pumpingsystem. The other end of the pipe chamber is connectedwith galvanized iron ducts leading over the station plat-forms. These ducts have grated openings about 20 by 28inches, which discharge directly downward toward the plat-forms. The current of water is in counter direction to thatof the air. The plant was started on August 29. and was run con-tinuously into October of the present year, and intermittentlyas required since. It was originally planned to use 400 gal-lons of water per minute, but when the wells were sunk itwas found that the level of the water was lower than ex-pected, and rather than lose time in lowering the pumps tothe bottom of the station, it was decided to place them
