clearly evident in the experimental work. The same is true, though 
toa less extent, in regard to leaf roller. The reduction in the total 
wormy apparently indicates a marked benefit for three applications 
as compared with one or two, though we are inclined to attribute 
considerable of this apparent benefit to the decidedly larger crop on 
plot... Lhere is a marked benefit in the reduction of end wormy, 
side July and side August in both plots 2 and 3, though in the case 
of the “‘ shallow” the difference is offset in large measure, if not 
entirely, in the case of plot 3 by the larger yield; in fact there is a 
little greater proportionate reduction in the percentage of total 
wormy than in the percentage of “shallows” between plots 2 
and 3. 
The check trees show a marked contrast to those which were 
sprayed, there being only about half as much perfect fruit, a con- 
siderably higher percentage of scabby apples and a much greater 
percentage of wormy fruit. The principal benefits of spraying as 
evidenced by this table lie in the almost complete elimination of end 
wormy, the great reduction in side July, and side August and when 
increases in the latter two are eliminated we have nearly the same 
ratio existing between the total wormy and the “ shallows” as in 
the case of the sprayed plots. 
Kendall Orchard 
The experiments of the last two years were continued in the 
greening orchard of Mr H. E. Wellman of Kendall, the plots being 
practically the same as in 1916, except that the check trees X and 
Y were in the twenty-third row north from the driveway. The 
location of the plots is given in detail in the report for 1916 on 
page 19 and need not be repeated here. 
The first application was made June rath, Dow’s arsenate of lead 
being used at the rate of 23 pounds to so gallons of water and Dow’s 
lime sulphur wash at the rate of 1 to 4o. The Friend “ spray gun ”’ 
was employed with a 3 foot extension and a pressure of 200 pounds. 
The spraying was done entirely from the wagon, and owing to the 
large size of the trees it was frequently impossible to hold the nozzle 
at such a distance as to give the most satisfactory results. Further- 
more, this first treatment was rendered more difficult by the muddy 
condition of the orchard, this making it almost impossible to stop 
the team with any degree of accuracy. The weather conditions 
were nearly perfect, it being a sunny day with little wind. The 
western row had been given a semidormant spray of 12 gallons of
