bellows, fig. 84, a, to which is attached a canister, 6, with a moveable 

 nozzle, through which the smoke escapes, c. The details of the canister are 



Fig. 84. Read's fumigating bellows, 



shown in the section, fig. 85, which is one- third of the natural size. In 

 this section d is the bottom socket or cap ; e, the plunger, which keeps down 

 the tobacco ; /, the nozzle of the bellows ; and ^, the tube by which the 



smoke escapes, unscrewed to show the ball- valve. 

 In using this machine, unscrew the bottom socket 

 of the canister, and turn up the canister, so that 



the perforated plunger may fall to what becomes, 

 when in use, the upper end h; put in the to- 

 bacco, or tobacco-paper, replace the socket, hold 

 the apparatus in the position shown by fig. 84, 

 hold the bottom of the canister over a piece of 

 lighted paper, expand the bellows, and the flame 

 will rush in and ignite the tobacco. Then by 

 continuing to use the bellows in the ordinary way, 

 the tobacco will be consumed in smoke, which 

 may be directed by means of the issue pipe c at 

 pleasure. Immediately after using the machine, 

 immerse the canister, which will now be very hot, 

 e I in water ; unscrew the top and bottom, and wash 

 I and wipe the valves and pipe, so as to leave the 

 I whole perfectly clean. If this is not attended to, 

 I the oil of the tobacco will soon form a thick 

 I glutinous coating, which will prevent the valve 

 I ^ from acting properly. When a large house is to 

 ^ be filled with tobacco smoke, a fumigating pot,

such as fig. 86, may be used. It is 

 made of sheet-iron, holds about 

 three pounds of tobacco, and is 

 placed on the outside of the house,
