The invasion of the cotton states l>y the cottcm boll Aveevil 

 lenders more important than ever before careful studies of 

 the early varieties. It has been found that only the earliest 

 varieties can be profitably grown in infested regions, even 

 Avhen all other known methods of combatting the weevil are 

 employed. 



The rapid spread of the weevil eastward in Louisiana dur- 

 ing the past season makes it important that the farmers of 

 Alabama should be ready for this invasion as promptly as 

 possible. It would be well for every neighborhood, and 

 perhaps for every farm, to have at least a small portion of 

 its crop in one of the very early varieties so that seed of early 

 varieties may be everywhere available when urgently needed. 



It is easy to determine at a glance that one variety is earlv 

 <md another late. l>ut it is less easy to indicate the relative 

 earliness of intermediate varieties. In the two tables which 

 follow the figures show how many bolls had opened on a 

 given date early in Septembei- out of every 100 bolls matur- 

 ing during the entire season. 



These figures are based on counts of bolls on five 

 selected plants of each variety made by Mr. ( '. H. Billingsley, 

 of the United States Department of Agriculture.
