From this it descends bygravity in a pipe that extends the entire length of theboiler room. There are leads to each boiler so that a uni-form distribution of this condensation is insured. Stopsare placed in each branch so that they can be cut out forcleaning and repairs should occasion require. ENGINE ROOM. The engine room is lighted by large windows on thenorth and west sides and by a monitor roof. The latter issupported by trusses resting upon central girders and a rowof lattice posts extending through the center of the room. There are two traveling cranes of twenty tons capacityeach.
