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

 plots 1 or 2, the product of individual trees ranging from 90 to 471 

 apples, while the percentage of wormy fruit varied from 12.21 to 

 17.26, the average for the plot being 14.27 per cent. This higher 

 percentage of wormy fruit is correlated to a certain extent with the 

 much smaller crop in comparison with the other two plots. Here, 

 as in the preceding plots, a very large percentage of the wormy 

 fruit, namely 12.06 of the 14.27 affected, showed the characteristic 

 " shallow " injury due to the work of larvae coming from late- 

 deposited eggs. There is a marked gain in the percentage of perfect 

 fruit and a corresponding decrease in the scabby apples, a condition 

 not adequately expressed by the figures, since the infected areas on 

 the apples from plot 3 were decidedly less than those on plot 2 and 

 much smaller than in the case of plot 1.
