Plot 3 produced the largest crop, approximately one-half greater 
than that of each of the two preceding. There is a higher per- 
centage of perfect apples and also a larger proportion (33.71 per 
cent) of scabby fruit. There is a decidedly smaller percentage of 
wormy apples, namely, 10.44, which in our estimation is attributable 
in considerable measure to the larger crop. The variation per 
tree ranged from 8.76 to 14.64, the former being one of the more 
heavily fruited trees and the latter from the one with the lightest 
crop. The end wormy average nearly as in the preceding plot, 
namely, a little over one-fifth of 1 per cent (.22 per cent), while 
practically but 9 per cent of all the wormy apples show the shallow 
type of injury. 
Plot 4 was laid out for the purpose of getting a little comparative 
data in relation to the injury to the different varieties. Unfortunately 
it was not possible to classify the fruit on the ground under the 
Baldwin trees, namely, trees B and C, though this was done in the 
case of the greenings, trees A, Dand F. There was a light crop on 
the latter, the three trees producing only about two-thirds of the 

1 The apples on the ground were included in the tabulation of trees A, D and F, though owing 
to a misunderstanding this was not possible for the other trees in this orchard.
