The yield on plot i varied from 588 apples on tree A to nearly 

 2000 on tree F. There was practically no crop on tree E and hence 

 this was not picked. It will be noted that the perfect fruit ran 

 moderately high and there was not a very great variation in scabby 

 apples, except in the case of tree F, which was exceptionally clean, 

 producing only 5.88 per cent of fruit thus affected. The percentages 

 of wormy apples varied from 13.95 on tree D to 22.32 on tree C, a 

 difference certainly not due to the crop, since the more heavily 

 laden tree had the larger percentage of wormy apples. The average 

 percentage of wormy apples for the entire crop amounted to 18.93. 

 This last figure should be compared with the 54.06 and 35.33 per 

 cent of wormy fruit on the check trees, the average for the two 

 being 41.69. It should be noted that nearly two-thirds of all the 

 apples on the entire plot showed the characteristic shallow type of 

 injury, that the end wormy were reduced to almost half of 1 per cent 

 and the side July and side August are slight though relatively hardly 

 greater than was found on plot 1 of the Kendall orchard last year.
