The yield of plot 2 was approximately half of that in plot 1 and 

 amounted to 3064 apples, the number to each tree ranging from 73 

 to 991 and the percentage of wormy fruit varying from 5.61 to 16.43, 

 the highest in this instance being on a tree producing only 73 apples. 

 Here, as in the preceding plot, a very large proportion of the apples 

 damaged showed the characteristic " shallow " type of injury pro- 

 duced by late-hatching larvae. The fruit infested by the codling 

 moth in this plot amounted to 8.68 per cent. This second appli- 

 cation shows a marked increase in the perfect fruit and a corre- 

 sponding decrease in the number of scabby apples, the difference 

 being really more marked than indicated by the figures, since many 

 of the scabby apples were decidedly less infected than was the case 

 with the fruit from plot 1.
