jarring of the trees or of planting in poultry yards, cannot be de- 

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

 or Loudon 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 results, and it is to be hoped that so simple and cheap a 

 remedy may be found successful. Another season this matter will 

 be fully tested on our grounds. The varieties growing in our orchard 

 are : Yellow Spanish, 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 iii ripening, and in man}' 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 fjlirly 

 good condition. 



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

 rotting of the fruit iiave 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 

 vineyard. 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 couutry and Europe for the destruction 

 of these most serious obstacles to grape growing in America. 



The following table shows the condition of the atmosphere during 

 the two most critical mouths, together with the amount of mildew 

 noticed upon the foliage or fruit.
