For this purpose there is an air com-pressor, of the Laidlaw-Dunn-Gordon single-fly-wheel type,\> ins. x 14 ins. x 12 ins. in size, which maintains a pressure ofabout 15 lbs. Water is pumped from the receiving tank to anoverhead tank, and from this it flows by gravity to a Websterfeed-water heater underneath the framework supporting thechimney, and thence goes to the feed pumps in the boiler CROSS SECTION OF BUILDING LOOKING WEST AND CROSS-SECTION OF ANNEX RAILWAY PLANT The feed-water heater receives the exhaust from the condenserair pumps and the feed and other pumps about the plant. The equipment of the station, as described, covers an elec-trical plant which is in excess in its demand for steam overwhat the boiler plant was normally expected to produce. Inother words, the boiler plant was installed with the provision ofa relay, or idle unit, to allow for extensive cleaning or repairsof any other units. The demands for current, however, led tothe installation in the engine room of additional machinerybeyond what was originally calculated, so that at times all boilers have to be operated. This problem is to be solved byincreasing the original rate of evaporation in the boilers byproviding a second smokestack. It appears that the presentchimney has insufficient cross-section to carry away the gasesin case it were increased in height to raise its cap
