these ends where they would come in the presence of the full power 

 of the heat there would be little danger of the insect passing through 

 unharmed. It would be safer, however, to have the edges of the 

 steam chest high enough so that when covered with the blanket all 

 portions of the tobacco would be subjected to a like grade of heat. 



After the tobacco is cut, the process of drying occupies so much 

 time that there is danger the beetle will deposit eggs on it. This 

 can be avoided by a substantial dry-house, separate from the fac- 

 tory, which can be kept very clean and tightly closed at night. By 

 using care as to the condition of tobacco which is placed in the dry 

 house, it can be kept safe during this period. Where trouble is 

 apprehended quantities of cut tobacco should not be kept on hand 

 unless stored in safe boxes. The better way would probably be to 

 fill an order a little late than with material which is liable to be in- 

 fested. 



During the season when the beetle is flying about the factory, 

 each operator in the cigarette room should be provided with a neat 

 and closely fitting box which would hold approximately suflScient 

 tobacco for the day's work. What remains at the close of the day 

 each operator can put in his box, and thus prevent the beetle from 

 depositing eggs on the portion which remains over night. The man- 

 ager of this department could in a short time see that the tobacco 

 was properly protected for the night. 



For storing the cigarettes boxes of convenient size, which shut 

 very closely, could be used, and thus the danger of the beetle en- 

 tering be averted. By ridding the factory of infested stock, remov- 

 ing such material as would afford a breeding place, and adopting 

 some such precautions as suggested, it is reasonable to suppose the 

 pests could be controlled. 



From the knowledge of the natural history of the beetle already 

 determined quite an important result is reached. In case of goods 

 manufactured during the summer, if it is feared the insect is pres- 

 ent, they may be stored for 90 days, when if no signs of the pres- 

 ence of the insect are detected, it would be safe to ship the goods. 

 This would also afford a protection to the manufacturer. If the 

 work of the beetle was not evident within 90 days from the time the 

 goods left the factory the manufacturers would be relieved of the 

 responsibility. 



Fumigation as a Remedy. — From experiments, both on a large 

 and small scale, it has been found that the insect can be destroyed 

 by treating with the fumes of bisulphide of carbon without in the 

 least affecting the flavor or appearance of the cigarette. As this
