The yield for plot 2 is nearly the same as for plot 1. There is a 

 decidedly larger percentage of perfect fruit, namely, 62.50 and a 

 slightly smaller amount of scabby apples, namely, 17.38. Leaf 

 roller infestation was only about one-half, being for this plot 8.24, 

 whereas in plot 1 it is 16.63 P er cent. There is a slight reduction 

 in the wormy fruit, the variation for individual trees ranging from 

 13.32 per cent for tree A to 26.58 for tree D. The former was one 

 of the more heavily laden trees, while the latter bore a very small 

 crop. The average percentage of wormy fruit for the entire plot 

 was 16.17, less than one-fifth of 1 per cent (.17 per cent) being end 

 wormy and a relatively high proportion, 13.27 per cent, showing the 

 shallow type of injury.
