Tile bolls examined all showed distinct extermil signs of weevil 

 injury. .Vmong them, howcxcr, fully one-fourth of the t(ital number 

 of locks were found to have no noticeable internal injury, and prob- 

 ably a majority of these locks would have matured had the bolls 

 been allowed to remain upon the plants. As the bolls examined 

 were .selected especially for weevil injury, it appears that their con- 

 dition would probably be wor.so than the average in fields where 

 the weevil Inis done its worst damage. The tigures are of in((>re.st,
