The entire coal-handling equip-ment, together with the ash-handling apparatus, is being sup-plied by the Mead-Morrison Mfg. Co., of New York. The ash-handling system will comprise a line of narrow-gage railway cars, passing underneath the ash-chutes in theboiler house basement, which will deliver the ashes to anelevating conveyor in the coal tower, raising them to a 1000-tonash-storage pocket. Cast-iron chutes are carried from thefurnace ash bins of the boilers upon both floors down to out-lets over the track for dumping direct to the cars.
