ing with bordeaux-mixture at this time for the prevention of this 
disease. . 
Results on apple aphis—Small colonies of lice made their 
appearance in the opening leaf clusters of the sprayed and 
unsprayed trees, but the numbers were too small to indicate the 
relative effects of the different treatments. The rosy aphis was 
later much more abundant and was usually to be found upon the 
lower branches and towards the center of the tree. This species 
did very little injury and the amount of infestation showed no 
apparent variation with respect to the treatments. 
ORCHARD V. (ONTARIO CO.) APPLES. 
These are young trees and were top-grafted in 1895. The varie- 
ties represented are Jonathan, Ben Davis, Gano and Shackleford. 
The trees have received very careful attention in every respect. 
The applications of the bordeaux-arsenical mixtures were made 
to four hundred trees on May 10, June 2 and June 16. On Octo- 
ber 4 the fruit was picked and the yields of a number of trees 
were sorted with respect to injuries by the codling moth, with 
the following results:
