The yield on plot 1 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.
