INSECTS INJURIOUS TO CLOTHES 201 



receptacles for the storage of materials liable to be in- 

 fested with moths and will last for years. 



The upholstering on furniture and carriages is much 

 harder to protect from the moths. Badly infested up- 

 holstered furniture should be placed in a small tight room 

 and thoroughly fumigated with hydrocyanic acid gas. 



Some good can undoubtedly be accomplished by spray- 

 ing them several times during the summer with benzine or 

 gasoline. These volatile liquids will not stain if they are 

 reasonably clean. Care should be exercised regarding 

 lights because gasoline and benzine are very inflammable. 



COLD STORAGE 



Cold storage plants for fruits and meats are common 

 nowadays in all cities and in many small towns. These 

 plants are available for various uses, among which is the 

 storage of furs, rugs, and other valuable woolen goods 

 during the summer season when the owners are out of 

 town. In fact, this is fast becoming in cities a universal 

 way of storing household goods. 



L. O. Howard reports some careful experiments carried 

 out mainly by Albert N. Read, manager of a cold storage 

 warehouse in Washington, D.C. It was demonstrated 

 in this series of experiments that a continuous tempera- 

 ture of 40 degrees F. is sufficient to maintain the larvae of 

 the case-making clothes moth in an inactive dormant con- 

 dition. It was also shown that the larvae could exist at a 

 temperature as low as 18 degrees if it were continuous. If, 

 however, the larvae were taken out and revived by warmth 

 and then returned to the low temperature they almost 

 invariably died. These results are in accord with the
