the support of the hams, &c., break, the latter cannot be hurt by coming in contact with the fire or ashes, as sometimes happens in the regular smoke-house. The ordinary smoking-chimney is described by Robinson as follows:--“It should be placed in some outhouse or shed, or even in a yard, so that no annoyance may be caused to the inmates of the dwelling, by even the smallest escape of smoke. It should be built of brick, and carried up to the height of 8 ft. at least from a brick or stone floor, 1 yd. wide and 2 ft. deep inside measure, and at the height of 3 ft. from the floor there should be a door frame reaching to the top of the chimney, or nearly so, on which a door, well jointed and fitted, must be hung. A small door of 1½ ft. square, of sheet iron, must also be made on the floor, through which the embers from the fire may be raked, and fuel or sawdust added from time to time, as the process of smoking goes on. A false floor, of sheet iron, perforated all over with holes, ¾ in. in diameter and 4 in. apart, must be placed (not fixed) inside the brickwork, on a level with the bottom of the wooden door-frame, viz. 3 ft. from the floor; this will serve to scatter the smoke equally in its ascent--be a preventive to danger from flame, if any should arise--and receive any small fish that may fall off the frames on which they are suspended. Four strong iron rods, with movable hooks on them, must be inserted in the brickwork near the top of the chimney, from which may be suspended sides of bacon, hams, heavy salmon, &c. &c. An outlet for the smoke must be made at or near the top, and a wooden pipe, 4 in. square, with a slide or valve in it (to confine or dismiss the smoke at pleasure), will completely rid the premises of any unpleasant odour. On each side of the chimney inside, and above the false floor, a framework of inch-square scantling must be fixed, with bars of wood of the same size nailed across to rest the rods and frames on; the bars must be fixed 11 in. above each other, and be continued until they come to the iron rods. “The wooden rods or spits on which herrings are to be hung should be perfectly round, 3 ft. in length, ½-¾ in. in diameter, and pointed a little at one end that they may more easily be run through the gills of the fish. They may be of deal or any other tough wood, and 16 herrings will smoke conveniently on each rod.
