boll rot; Toole has small bolls; Cleveland readily drops the 

 seed cotton from the burs; Dixie and Poulnot are late. 

 Each grower can decide which of these faults he considers 

 least objectionable, or whether, to avoid all of them, he 

 will choose some good variety which, at this Station, has 

 proved less productive, — for example, Triumph. 



The earliest varieties grown in 1909 were Trice, Broad- 

 well Double-jointed, Simpkins and King; the last two 

 appeared to be practically identical, 



A number of varieties additional to those mentioned in 

 the table were grown for observation on areas too small to 

 determine the yields per acre. 



NUMBER OP DISEASED BOLLS. 



Anthracnose of the bolls, generally called boll rot, was 

 so prevalent on the Station farm in 1909 that an unusual 

 opportunity was offered to test the relative susceptibility 

 of different varieties to this disease. The figures in the 

 following table are based on counts made in winter of the 

 total number of burs and of the number of bolls that had 

 been so injured as to cause the loss of one or more locks. 

 Diseased bolls as here reported consisted chiefly of those 

 injured by anthracnose, but the figures include also smaller 

 losses due to another disease. They also doubtless include 

 a small number of bolls damaged by boll worms.
