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, D and 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.
