except to use it in feeding to animals. It would be best, 

 however, to kill the larvae and beetles by fumigating the 

 cereal with carbon bisulfide, to make sure that none of 

 them escape to infest other household materials. This 

 may be done by setting a teacupful of the liquid on top of 

 the flour in a tin dish and covering the barrel tightly. 

 Allow it to stand two or three days in order that the gas may 

 have time to penetrate into the flour as far as possible. 

 In the meantime, do not go near the barrel with a light of 

 any kind, for the gas of carbon bisulfide is inflammable 

 and explosive.
