The two check trees produced on an average nearly as many 

 apples as those in plot 2 and yet there were only 17.41 per cent of 

 perfect fruit, 29.48 per cent being affected by scab and 7.69 per 

 cent damaged by leaf roller. A very marked difference in wormy 

 apples is noticeable, the percentage for the two trees being 56.61 

 and 66.16 with an average of 60.68. The end wormy constituted 

 22.16 and 35.33 per cent, respectively, with an average of 27.77, 

 while the side wormy ran up to 36.31 and 45.36 per cent, the average 

 being 40. 1 7 per cent. There were, however, relatively few " shallow ' ' 

 affected apples, these amounting on the two trees to 16.01 and 12.55 

 per cent, respectively, giving an average for the two of 14.53. The 

 marked contrasts are too evident to require further emphasis.

The summary tabulation given above brings out in a general 

 way the results obtained in this orchard, and it is a source of regret 

 that the crop was not "larger and more uniform so that comparisons 

 would have been of greater value. It will be seen that in plot 2 t
