upon. It is possible, however, that the use of Paris green or London 

 purple while the fruit is still quite small may be effectual, although from 

 the nature of the condition we are unable to see how. Experiments 

 made at the Ohio Experiment Station seem to indicate favorable re- 

 sults, and it is to be hoped that so simple and cheap a remedy may be 

 found successful. Another season this i"natter will be fully tested on 

 our grounds. The varieties growing in our orchard are : Yellow Span- 

 ish, Gov. Wood, Black Tartarian, Early Purple, Royal Duke, May Duke, 

 Early Richmond, Belle Magnifique, Downer's Cleveland, Tradescants, 

 Black Heart, Downer, Reine Hortense, Napoleon, Rockland, Bigarreau, 

 Montmorency Ordinaire. 



GRAPES. 



Owing to the unusually cool summer the grape crop has been very 

 backward in ripening, and in many localities was cut off entirely by the 

 early frosts. Where it has escaped however, the warm, moist weather 

 following the frost has caused the crop to mature in a fairly good con- 

 dition. 



Very little mildew has appeared, and only a few cases of serious 

 rotting of the fruit have been reported. 



In order to make a careful study of these two diseases a series of 

 weather observations have been made, taken in the centre of the vine- 

 yard. By this means we hope to become thoroughly familiar with all 

 the conditions under which they become destructive. It is proposed 

 the next season to make a thorough test of the numerous remedies 

 recommended in this country and Europe for the destruction of these 

 n*st serious obstacles to grape growing in America. 

 f The following table shows the condition of the atmosphere during the 

 two most critical months, together with the amount of mildew noticed 

 upon the foliage or fruit.
