in 



dry, hot weather. The fact that grape vines growing in 

 sheltered positions, and the occasional occurrence of vines 

 growing upon trees, retaining their health, while branches 

 near by will be mildewed, seems to show that the foliage of 

 the tree protects them, and is some evidence that the cause is 

 atmospheric. We are inclined to think that shelter, a well 

 drained soil, and the avoiding of strong animal manure, will 

 do much to prevent this evil.
