I also transcribe a few notes made September 28, 1885, upon mildew. 

 The American grape mildew, PeronosjHyra viticola, attacks the under sur- 

 face of the leaf, where it may be detected in the form of little frost-like 

 patches. If the fungus is generally distributed over the under surface, 

 the upper surface will show the disorder by its yellow color and the 

 final browning and death of the leaf. This mildew must not be con- 

 founded with the fuzzy whiteness on the leaves of many varieties. The 

 mildew is in patches, and is peculiarly frost-like, while the natural 

 whiteness is continuous and made up of cob-webby threads. The varie- 

 ties which have suffered most from mildew are as follows : Delaware, very 

 much injured, the leaves unhealthy all the season and falling off by the 

 middle of September, or before. Next in order come Merrimac, Rogers' 

 5, Agawam, Salem, Poughkeepsie Red, Empire State, Alvey, Ovvoss'o, 

 Walter and Haskell's Nos. 64, 75, 229, 224, 122, 188, 136, 366, 420. Has- 

 kell's Nos. 122 and 136 are the fuzziest leaves which I have known to be 

 much attacked by mildew. The varieties injured to some extent, not seri- 

 ously, are Herbert, Isabella, Telegraph on young leaves, Haskell's Nos. 128, 

 309, and 387. Brighton has some mildew, but the vines not injured; same 

 with Seneca. Goethe shed its leaves very early, but the cause does not 

 appear to be mildew entirely. The leaves of Haskell's Nos. 224 and 229 are 

 very poor and small at best. The varities which withstood mildew best are 

 Concord, Worden, Champion, Woodruff Red, Niagara, Hayes, Ulster Pro- 

 lific, and Haskell's Nos. 325, 12, 317, and 33. The foliage of the Wood- 

 ruff Red is remarkably thick and vigorous; also Haskell's Nos. 12 and 317. 



We fruited Ulster Prolific this year. It is like the Delaware in color, but 

 larger, firmer, and fully its equal in flavor. Its leaves are rather small, but 

 very firm and vigorous. It gives much promise. 



We have three vineyards, comprising about 850 plants.
