' Other exiKTiments have proved tliat a sudden heat of 75" Kahr. is sufllcieut to destroy 

 the^ insects, without burning them ; and a simple etHcacious nietlio<i is mentioned in the 

 Tenncswe Agriculturist, quoted by Mr. Gayi.obd in Ids essay. " If a hogshead, with one 

 head removed, be inverted over a fire until thoroughly heated, a ml then immediately lilled 

 with nhiatand rih<-ad<-<l, all weevils in the grain will lie killed, and the grain maybe 

 kept in safety till wanted for us*-."

 he reeeivi's n-t many as eight hundred Imus of grain at a time : tln-se U'come heate«l through
