substance treated when exposed to the air, and even foodstuffs have 
been treated without affecting their edibility in any way. Tobacco or 
cigars when properly aired do not retain the odor of the gas, and 
the quality and flavor are not perceptibly changed. 
While carbon disulphid is not as effective as hydrocyanic-acid 
eas, the ease with which it may be employed makes it the more desir- 
able fumigant, particu- 
larly when the mate- 
rial to be fumigated 
occupies a small space. 
The liquid carbon di- 
sulphid has merely to 
be poured into a shal- 
low dish, placed near 
the ceiling of the com- 
partment to be fumi- 
gated, and allowed to 
evaporate. The method 
is a favorite one with 
many cigar dealers, the 
main objection being 
the danger of fire. A

soon as infested stock is detected it is fumigated promptly, and in 
this case there has been small loss from the tobacco beetle. 
The fumigating closet, shown in figure 16, was found to be a con- 
venient size for cigar fumigation. Its dimensions are 2.5 by 2.5 by 
6.5 feet. The sides are of matched boards. The inside is lined with 
sheet zinc. The door and fastenings are similar to those commonly 
used on refrigerators. Strips of heavy felt were attached where the
