During the heating season the latter engines exhaust intothe heating system mains, as well as all of the steam ham-mers, so that all waste steam is saved and utilized as far aspossible. The distributing pipe lines are carried undergroundin tunnels and are all well insulated from heat losses. Compressed Air System. Compressed air at 100 lbs. pressure is supplied by the 2,000cubic foot, compound air compressor located in the powerhouse. Two large steel reservoirs are located just outsidethe power house, which receive the air and cool it. Fromthere it is distributed by means of a system of undergroundpipe lines to all buildings and departments. Numerous out-lets are located at frequent intervals, provided with hose con-nections, so that air for the operation of drills, reamers,riveters, clippers, caulkers, expanders, and a great manyother purposes is always at hand.
