 cies are discussed and its life history briefly 

 treated. Early thrashing is recommended in 

 the case of wheat, but where the wheat must be 

 left in the field the individual farmer should 

 disinfect his granaries every year soon after 

 the wheat is put in. This is best done with 

 bisulphide of carbon, aiid the author gives the 

 proper quantities to be used in rooms of various 

 sizes. Against this insect as a corn pest the 

 practice has been adopted of growing only such 

 vaiieties of corn as have a close-fitting husk
