situation is critical, and unless the proper measures are taken 
at once the disease will have reached a range beyond any possible 
control. The fruit-grower must face this problem: that, irre- 
spective of his innocence and his personal feelings in the matter,

ANGULAR LEAF-SPOT 
Caused by Cercospora angulata Winter 
This leaf-disease of currants is common in Iowa and New 
York. It is also found in Ohio, Michigan, West Virginia, 
Maryland, Nebraska, Wisconsin and Rhode Island. In some 
years it is very destructive. 
The spots produced by Cercospora angulata are readily 
recognized. On the upper surface of a leaf the spots are of a 
paler color than the surrounding healthy tissue. The under
