Discussion OF CHANGBS OCCURRING DURING GROWTH. 
In terms of total solids the composition of the summer apples is 
shown graphically in figures 13 to 15, inclusive. The results of this 
work give a much more complete account of the life history of the 
apple than was obtained in the previous year. By referring to the 
graphic chart for the Early Strawberry (fig. 18) as an illustration of 
the summer apples, it is seen that the starch content increased from 
June 11, 1903, the date of the first examination, until June 25, when 
the maximum starch content was attained. From that time until 
August 5 the starch steadily decreased. and on that date the sample 
examined still contained 6 per cent of starch based on the total solid 
content of the apple. 
The apples were not in a good state of preservation, however, for 
by this time all had fallen from the trees and none in a condition suit-
