‘by the applications. The experiment was made upon one 
side of a tree of the common Siberian crab, leaving the 
other side untreated. 
The past season the applications were repeated upon this 
tree in the same manner as in 1885, and a tree of Seckel 
pear, on which the fruit has been much injured in past sea- 
sons by another species of Hustcladium, was also treated on 
one side. 
The solution was applied to both the crab and pear tree 
four times, viz., on April 22, May 6, May 10 and May 17. 
The first three applications were at the rate of one pound 
of the hyposulphite to ten gallons of water, and the last 
was of half that strength. It was found that the second 
and third applications injured the foliage of the pear tree 
slightly, and hence the last one was diluted one-half. 
‘The results in the case of the crab tree were very strik- 
ing. The part of the tree sprayed with the solution bore a 
fair crop of medium sized fruit, while the other brought no 
fruit to maturity. Both sides of the tree bloomed profusely, 
and early in the season both had a fair setting of fruit. I 
am not sure whether or not as much fruit set on the side 
not sprayed as on the sprayed side, but when the fruit on 
the latter had ripened, only specimens ruined by the 
fungus were to be seen on the side of the tree not sprayed, 
In the case of the pear tree, the result was less striking. 
The fruits were picked August 28, and the yield from each 
side assorted into two qualities. Only those not sufficiently 
injured by the fungus to affect their market value were 
placed in the first quality. 
Of 486 fruits picked from the sprayed part of the tree, 
290, or 59.65 per cent. were found to be in the first quality. 
Of 213 fruits picked from the side of the tree not sprayed 
115, or very slightly less than 54 per cent. were placed in 
the first quality. 
It appears that the slight difference is in favor of the 
sprayed side. It should be added that the second quality 
from this side was perceptibly better than from the side not 
sprayed. 
AN APPLICATION FOR PEAR BLIGHT. 
At the suggestion of Prof. Arthur, the same solution was 
applied to the foliage of one Boussock and three Bartlett. 
pear trees to see whether it might not act as a preventive 
of the pear blight. The trees were sprayed on the same 
dates as noted above, the first application being made before 
the leaves were fully developed. One of the Bartlett trees 
was attacked with blight during the summer, and thus the 
question is answered in the negative.
