cum Fckl. The tree chosen for the experiment was one of the com- 
mon Siberian(?) crab that had been very subject to injury from this’ 
fungus in previous years. 
On May Sth, we syringed one half of the tree with a solution of 
hyposulphite of soda, at the rate of one pound to ten gallons of water, 
and repeated the application on May 9th, and May 15th. 
During the summer, the foliage appeared less injured by the fun- 
gus upon the syringed half of the tree. On Sept. 19 we picked a 
quantity of fruits from the syringed part of the tree, and from the 
part not syringed, and assorted each lot into three qualities. In the 
first quality we put only the fruits not attacked by the fungus, in 
the second, those attacked in but one place, and there but slightly, - 
and in the third, those much injured. ‘The results appear in the 
following table, in which the percentage of the fruits of each quality 
are given for the syringed and unsyringed part of the tree. Wealso 
give the weight of 100 fruits in each quality, as an indication of the 
amount of injury wrought by the fungus:

It appears that in the syringed portion of the tree the per cent. of 
uninjured fruits was double that in the unsyringed portion, while 
the percentage of the third quality, or much injured fruits was one 
half less. It also appears that all of the fruits on the syringed por- 
tion were larger in size than those on the unsyringed portion. We 
also noted that there were many more decayed fruits on the unsyr- 
inged portion of the tree. 
The indications are, therefore, the hyposulphite of soda proved ben- 
eficial. The solution may be applied at the same time as the Paris. 
green and water, where the latter is used for the codling moth, thus 
avoiding the expense of a special application.
