In the case of the sprayed plats, as would be expected, the propor- 
tion entering at the calyx is greatly reduced, and there is a corre- 
sponding increase in the proportion entering the fruit at the side, 
owing to the lesser efficiency of the spray at the latter place. This 
is shown for each of the plats in Table IV.

As between the several sprayed plats there is considerable variation 
in the number of apples wormy at calyx, side, and stem, which is of 
significance in connection with the character of the treatments given. 
To compare these points better Table V has been prepared.

a As someapples wereentered at more than one place, the sums of the percentages for calyx, side,and stem 
slightly exceed the total percentages of wormy apples.
