1877. The fumigating pot (fig. 496.) is made of sheet iron, and the bellows it is worked with are double-blasted. It holds about three pounds of tobacco, and acts on the outside of the house. In the figure, a is the pot, and b the blow-hole, with a grate at the inner end; c is the lid, in which is fixed the tube (d) to convey the smoke into the house through an aperture made in the square of tin (e). Squares of tin, similar to this, are to be fixed in the upright sashes in the front of the house (one in every third or fourth sash), instead of panes of glass, in order that the pipe may be introduced in different places. The holes are fitted with plugs or covers, so as to exclude the air when the pipe is not in use. If there should be no upright sashes to the house, the tube will require another angle (f), and must be introduced through squares of tin fixed in the roof. This fumigating pot may be made at a trifling expense, and, with care, will last many years. (Gard. Mag., vol. vi. p. 553.)
