84 FUM WANTS 



The usual method is to burn stems or dust, or to vaporize hquid 

 extracts of tobacco, or to make use of a specially prepared punk now 

 on sale in stores. The last is usually the most satisfactory method. 



It is desirable in tobacco fumigation to generate the smudge near 

 the level of the floor, because it rises rather rapidly, and if generated 

 at the height of the benches, much of the strength of the fumigant will 

 be concentrated near the roof.
