Thestack is lined with 4)4 in. radial firebricks, set in fireclay. A waterguard is fixed at the top of the chimney, made of 3 in. angle ironturned down to cover the brick lining. The base-plate is of castiron, 2 in. thick and 15 ft. diameter, in eight parts, strongly ribbed. ; KIC- OF CAR. and joined by i;< in. bolls. The base. 21 ft. sq., is of Portland ce-ment concrete, 6 to l, and built upon a foundation of 25 pitch-pinepiles 12 in. by 12 in., and anchor bolts 14 ft. by 2^-2 in. diameterwere placed in position before the concreting commenced. The ad-vantage s claimed for the steel stack are saving of time in the erec-tion and cost in the structure. The time occupied in erecting wasabout five weeks, and the brick lining occupied 20 days. The sav-ing in cost over a brick stack was about 25 per cent. The steam piping is of steel, fitted with heavy screwed steelflanges, so arranged that any engine can be fed direct from the boil-er immediately behind it. Necessary valves are inserted to enableany faulty section in the piping to be cut out. This piping is fitted
