New York AGRICULTURAL EXPERIMENT STATION. 333 
The conditions governing the past year’s experiment were more 
favorable for making the test. The wood was well ripened and 
the weather in the fall leading up to the spraying season was 
mild, while the winter was less destructive to fruit trees, espec- 
ially those that were injured by insects and fungi. The applica- 
tions of sulphur washes were, on the whole, not detrimental to the 
trees and kept the scale well in control. 
From these results it is not safe to conclude that spraying in 
the fall is unattended with danger, as the resistance of a tree is 
largely determined by its health upon entering the winter. Like- 
wise the kind of spray employed and the hardiness of the variety 
are important factors. 
Whether or not it is advisable to spray in the fall seems to be a 
matter of expediency. A profitable orchard infested with scale 
will soon cease to be remunerative if neglected, and spraying, if 
it cannot be done in the spring, should be done in the fall; as the 
losses likely to follow will be more than compensated by the in- 
creased vigor of the trees and value of the fruit produced.
