The arrangement of the grate links in the gratechain, or band, which is 8 ft. 4% ins. in width, is clearlyshown in the illustration of the boiler fronts on page 337, aswell as also a coal chute from the pockets above to astoker hopper. One boiler is fitted with fire doors and station-ary grates, instead of a stoker, in order to burn shavings andrefuse from the wood mill and cabinet shop which will be de-livered to the boiler room by a shavings exhaust battery of boilers has a separate steel stack, 60 ins. indiameter and 150 ft. 1 in. high, natural chimney draft by in-dividual stacks having been considered preferable to forcedo
