y ashort neck at one end only. The upper cylinder is provided witha fire-box 3 feet 6 inches in diameter and 6 feet long, and its rearend is filled with about 100 two-inch tubes. The lower cylinderis completely filled with two-inch tubes. The fire-box is linedthroughout with fire-brick, and contains a grate surface 2 feet wideby 2J feet long. A hanging bridge-wall of fire-brick is placed inthe upper part of the fire-box in the rear of the bridge-wall properfor the double purpose of presenting a hot fire-brick surface to theflame before allowing it to touch the heating-surfaces of the tubesand tube-sheet, and of changing its direction so as to cause the gasesto thoroughly commingle and thus to insure complete combustion. Intesting highly bituminous coals, it might be advisable to have morethan one of these hanging walls, and to give the fire-box a greaterlength, to more certainly insure complete combustion of the gases.The gases of combustion pass through the tubes of the upper heater,

Air is fedto the fire, under the grate-bars, through a pipe leading from a fan-blower. The air is measured by recording the revolutions of theblower, and the measurement is checked by an anemometer in theair-pipe. Its weight should be calculated from the barometricpressure, and its contained moisture should al
