HOST PLANTS. 
While Glwosporium ribis may attack several different species 
of Ribes, it has a decided preference for R. rubrum to which 
belong the red and white varieties of cultivated currants. It 
has been frequently reported on R. nigrum, the black currant, 
but according to our observations it is not at all destructive to 
black currants, to say the least. While watching the progress 
of the disease in the Hudson Valley we examined several plan- 
tations of black currants, but in no case found any damage done 
to them by anthracnose. In one case a row of black currants 
stood between two rows of red ones. The red currants were all 
severely attacked by anthracnose, but the foliage of the black 
currants was perfect and apparently free from the disease. 
The cultivated gooseberry, Ribes grossularie, is also said to be 
subjeet to anthracnose. In the region where anthracnose was 
epidemic on currants there are several commercial plantations 
of gooseberries none of which were affected by the disease to 
any extent. ; 
It also appears that among the red currants some varieties are 
somewhat more susceptible than others. Our observations on 
this point are not as full as they should be and so we are unable 
to give a list of resistant varieties; but it is probable that this 
difference in susceptibility is sufficiently great to be turned to 
practical account in case anthracnose should become an im- 
portant factor in currant culture. 
On July 23, when the disease was in full sway, we made some 
observations at Middle Hope where four varieties of red currant, 
Fay Prolific, Victoria, Prince Albert and Pres. Wilder, were 
growing in the same plantation under practically the same con- 
ditions. On Fay Prolific, anthracnose had caused about two- 
thirds of the foliage to drop and Victoria had lost about one- 
third of its foliage; while Prince Albert and Pres. Wilder were 
perfect in foliage and practically free from the disease. Goose- 
berries growing nearby were also unaffected.
