The building itself is of brick, as will be seen fromFig. 3, with a roof supported by iron trusses and coveredwith slate. The chimney is 160 ft. high, and has a cleardiameter inside of eight feet. It will be noticed that the direct to the boilers, the main being located sufficiently feed wires enter the building through a perforated stone.

The drips from the steam pipes inthe basement are all returned by gravity to a tank, andautomatically pumped back to the boilers. A feature of the feedwater system is a large auxiliaryheater, through which the feedwater passes after goingthrough the individual heaters. This auxiliary heater ismade with a great amount of heating surface, exposing alarge body of water to the heat in the exhaust steam from slab placed in the gable of a bay window on one side, andgo directly to the switchboard located immediately backand in the center of one side of the engine room, and canbe reached at the back by a door leading from a smallentry or vestibule. The entire station has been arrangedfor permanency and economy, with a minimum amountof repairs, which are generally a large item in many pre-viously constructed stations.
