and varied from 27.16 to 38.77. Here, as in plot i, a very large 

 proportion of the apples were damaged by late-hatching larvae, 

 the injury for individual trees in no case falling below 25.19 per cent 

 and ranging from this to 34.69 per cent. The average infestation 

 for the plot was 31.64 per cent, of which .52 per cent was due to end 

 wormy infestation, 29.39 pei" cent to the characteristic side injury 

 damage and 1.93 per cent to late infestation by the second brood.

The yield from plot 3 was decidedly lower than in the case of the 

 two preceding, the product of individual trees ranging from 55 to 

 957 apples, while the percentage of wormy fruit varied from 21.27 

 to 39.02. This plot is characterized by an almost complete absence 

 of end-wormy apples, the infestation amounting to only .29 per 

 cent, while by far the most damage was caused by late-hatching 

 larvae and amounted for the plot to 33.51 out of a total plot infesta- 

 tion of 34.52 per cent.
