An annex to the buildingcontains a scale-room for tallying the weight of coal, and acomplete wash-room for the fireman, who has now become agentleman of leisure. Passing to the operative portion of the plant, it will, whencompleted, consist of eight horizontal return-tubular boilers nominal each, to carry a working pressure of UOlbs. These boilers are arrangedin two batteries of four eachin either end of the bnilding (one battery is now in operation),the space between being utilized as a pump-room. Followingthe progress of the coal, after it is weighed it is dumped on agrating at the end of the boiler house, shown in the general SECTION THROUGH view. The large lumps are easily broken by the teamsler, tliegrating serving as a screen to reduce the coal to a uniformmaxinuun size. From the grating the coal falls into a bucketelevator carrying it to an overhead conveyer extending tlie en-tire length of the boiler house, from whieli it distril)ul(S intosquare iron buid<ers having hopper bottoms. The b\inkersare supported on iron girders in front of and above the till bunkers the coal Hows by gravity through swivelsi)outs to the hoppers of the stokers. Each boiler is equipped with a Roney mechanical stoker,which furnishes a continuous sujiply of coal to the furnace ata slow rate of feed ; the quantity of coal and its distributionbeing regulated at will by hand-wheel adjustments on thetraverse motion. The power to ojierate the entin^ battery ofstokers is a small engine carried on ;i bracket at one end of eachbattery, and driving a slow-moving eccentric shaft. Fig T
