The engines, air compressor and pumps exhaust into thehot well through a similar pipe. A by-pass is placed betweenthese two pipes and is so arranged that the exhaust from thepower house and from the blow-off can either all be used in theheater, or part of it can be used for this purpose and the restbe blown into the hot well, or all of it can be exhausted intothe atmosphere by means of the back pressure valve in the powerhouse. A live steam pipe also leads from the boiler room tothe hot well. In a test, recently made, the power house was operated at itsfull capacity, as was also the hot air heating plant. The extraexhaust steam was turned into the hot well, heating it up toover 200 degs. F. The iarge washout pump took the water atthis temperature and delivered it to the two farthest washout

An underground blow-off system is being installed, with con-nections between the pits, so that engines which are to be washedout may be connected through the blow-off cock, and the dirtywater blown into an underground tank which overflows into thesewer.
