The steel framing of the boiler house and engine room are A cross section of the coal pocket closely resembles the let-ter W, this form being the necessary consequent of havinga double line of boilers with an alley between them, requir-ing a down flow of coal by gravity at points directly over theboiler fronts. Every portion of the bottom of the bunker isso arranged as to induce constant movement of coal in thebunker to the fire rooms, thus tending to prevent fires in thebunkers. No fire has yet been detected within the bunker. COAL-HANDLING PLANTThe location of the power station is such that it can receivecoal either by water or by rail, but as some water transpor-tation is necessary in order to reach the power station sitefrom the New Jersey terminals of coal carrying railroad

Conditions in the boiler house, are, however, morecomplex, chiefly by reason of the imposition of the coalpocket, which runs the entire length of the building. The steel stacks are independent of the boiler house, ex-cepting where they pass through the lower fire room floor,at which point the floor is built against the stacks.
