The data have been obtained by two methods: (1) From replies 
to letters of inquiry sent to fruit-growers, and (2) From personal 
observations made by the authors.

Apples have suffered from no disease —not even from scab. 
Rust has been the worst disease of blackberries. It has a tendency 
to reduce the number of prickles. Cherries have suffered most 
from fruit-rot which has been severe in a few localities. In the

the worst disease of currants. In the Hudson Valley it is not
