212 Report oF THE DEPARTMENT OF ENTOMOLOGY OF THE 
In each experiment with each variety of fruit the number of 
trees was divided as evenly as possible for treatment by the 
different sprays. Comparative tests were made of the above 
described washes in all of the orchards with the exception that 
in Messrs. T. C. Maxwell and Bros.’ orchard the self-boiled lime- 
sulphur-salt wash was omitted and in Mr. C. W. Ward’s orchard 
the self-boiled lime-sulphur-salt wash and the self-boiled lime- 
sulphur-caustic soda wash were omitted.

ORCHARD I. 
On peaches.—These trees were carefully examined during the 
early spring to note the effects of the treatments upon the buds. 
On May 1 there were evidences of injury upon the sprayed trees 
but the extent of the damage was difficult to estimate at this 
time. In comparison with the checks the buds of these trees 
were less advanced and fewer in number, while much of the 
wood of last year’s growth was dead for from six to ten inches 
from the tips. On May 9, blossoms and leaves appeared upon the 
unsprayed, and on May 12 upon the sprayed trees. 
To determine more minutely their conditions at this time a 
count was made of the number of blossoms and leaf buds upon 
four check trees and upon four trees from each of the different 
lots under treatment. The method followed in making this cal- 
culation was to ascertain the actual number of blossoms and 
leaf buds upon three representative branches of each tree. Upon 
these figures a computation was then made of the total number 
of blossoms and of leaf buds upon each tree. The results of 
this examination are given in the appended table which clearly 
shows the conditions of the trees under the various treatments:
