The yield on plot 2 was considerably smaller than that from plot 

 1, individual trees producing from 46 to 597 apples and the perfect 

 fruit varying from 40 to 200. There is a wide variation in the per- 

 centage of wormy fruit, this ranging from 8.69 to 24.78 with an 

 average for the plot of 18.39. The proportion of "shallow" 

 affected fruit approximates two-thirds of the wormy apples though 

 there is considerable variation between individual trees.

The yield on plot 3 was much larger than that of the other plots 

 and owing to time limitations the apples of but four trees were can- 

 vassed. These ranged in number from 2098 to 3092 and an exami- 

 nation of the other two trees showed they were about as heavily 

 loaded. The perfect fruit varied from 715 to 997 and the percentage 

 of wormy apples ranged from 13.63 to 16.72, a moderate variation. 

 Approximately three-fourths of the wormy apples showed the 

 " shallow " type of injury. The percentage of wormy fruit is quite 

 high when allowance is made for the heavy yield.
