The most promising field for improvement in conditions 

 undoubtedly lies in cultural methods. In the United States the 

 whole question of boll-weevil control, for instance, has practi-

 ties with regard to the different degrees of susceptibility to 

 insect attacks. Little has been done so far in this direction, but 

 it deserves study in the future.
