A steel chimney has been built in Chicago which, it is said, is 350 feet high, with an outside diameter of nine feet five inches. The steel varies in thickness from 5-32 inch at the top to three-eighths of an inch at the bottom. The lower seventy-five feet is lined with eight inches of fire brick, and above this the lining is of hollow tile, supported at intervals of twenty-five feet by angle iron riveted to the steel shell. The foundation is made of steel rails and one-beams laid in cement.
