The steeL smokestack of the mill is worthy of special mention. 11 is entirely without guys and is self-supporting, being 150 feet high and resting on a 10-foot concrete base. The diameter of the stack is 6 feet 6 inches. In the engine room, which adjoins the boiler room, the main power unit is an Allis-Chalmers condensing turbo-generator of 500 There is an auxiliary equipment of exciter engines, vacuum pumps, etc. There are three steam fire and boiler feed pumps, while in the mill are located 22 hydrants or stand-pipes, each connected with 2y2-mch standard gauge hose.

The band mills are equipped with 8-foot Avheels and 12-inch double cutting saws. The three carriages are run by 12-inch gunshot, steam fed cylinders.
