partially eliminate this possibility, yet in actual practice enough inter¬ 
gradation has been observed to make the personal equation an im¬ 
portant factor. This, coupled with the fact that the information 
was obtained in different years and by different people, leads the 
authors to attach very little significance to expressed differences 
between “very slight” and “none” as used for this disease. 
Coordinating the evidence in both Tables II and III, and con¬ 
sidering only those varieties on which there is fairly adequate infor¬ 
mation with respect to their behavior toward anthracnose and 
bacterial blight, tne resistant material isolated in this study may be 
classified as follows: 
1. Varieties apparently resistant to both anthracnose and bacterial blight:
