to 1 1 03, while the wormy fruit varied from 91 to 108. The per- 

 centage of infested apples exhibits no great variation, the lowest 

 being 9.43 and the highest 13. The last, as might be expected, was 

 found on the tree producing the smallest crop. There is likewise 

 comparatively little variation in either the number or percentage of 

 perfect fruit, except in the case of tree F, and the same is true of 

 the number and percentage of scabby apples. The number of 

 apples showing the typical " shallow " type of injury ranges from 

 approximately one-third to over one-half of the wormy fruit, the 

 average for the plot being a little below one-half.

Plot 2 produced a smaller crop than plot 1 and shows a relatively 

 greater variation in the yield, the product of individual trees ranging 

 from 298 apples to 987 and the wormy fruit varying from 34 to 127 

 apples, the percentage ranging from 7.42 to 12.86, this last occurring 

 on the tree producing the greatest quantity of fruit. This particular 

 tree stood by the roadside and it is possible that its proximity to the 

 fence may have interfered to some extent with the thoroughness 

 of the spraying. The number of apples showing the " shallow " 

 type of injury is larger than in the preceding plot, it varying for 

 individual trees from 21 to 77 apples, and the percentage ranging 

 from 4.38 to 8.38. Approximately two-thirds of the wormy apples 

 on this plot were injured in this manner.
