A beginning is said to have been made by H. 

 H. Webber, through combining the fine, long, 

 strong lint of the Sea Island cotton with the 

 large bolls and productiveness of the upland 



cotton. 



INSECT FOES OF COTTON 



It goes without saying that a highly special- 

 ized plant like the cotton, and in particular a 

 plant growing in subtropical regions, is subject 

 to the attacks of many insects. 



In fact, the distinguished entomologist, Dr. L. 

 O. Howard, enumerates no fewer than 465 

 species of insects that feed upon the cotton plant. 

 But among these there are four that are so pre- 

 eminent in their destructiveness as to make the 

 ravages of the others seem insignificant. These 

 are the cutworm (Aletia argillacea), the cotton

 from its aggression by planting a few rows of
