The Spraying of Orchards.

This number of treatments was unnecessary, for other trees which 

 were not sprayed until June 6th showed foliage which was apparently 

 just as healthy. The very wet weather seemed to brin^ on the 

 disease earlier than usual, but trees which had been sprayed resisted 

 the attacks almost perfectly. The fruit was very fair and large.

That borne by trees which was sprayed later, beginning June 28th, 

 was more or less spotted, and showed that the work had not been 

 done early enough. Yet in 1891 some quinces which were not 

 sprayed before July 13th preserved their leaves practically uninjured 

 until very late in the fall. Applications which are made to quinces, 

 as well as to so many other fruits, must be made intelligently and 

 with some regard to the season.
