In the case of the summer apples the curves representing- the changes 

 of composition in terms of grams per apple, as in the preceding charts 

 in which percentage composition alone was represented, are very 

 irregular, owing to the fact, as previously stated, that it was very dif- 

 ficult to secure a representative sample, the season of ripening being 

 so irregular that it was impossible to secure samples having an equal 

 number of relatively ripe apples. Irregularities of the curves in fig- 

 ures 21 to 24, representing the summer apples, are due to this fact. 



In the charts just mentioned the actual weight of starch increased 

 from the date of the first analysis until July IT in the case of the Early 



Subsamples stored in dark

Strawberry apples, and until July 2 in the case of the Yellow Trans- 

 parent. The percentage of starch in the Yellow Transparent apples 

 remained almost constant until July 23. The irregularities in the 

 curves representing the starch content in the Bough apples were so 

 great as to render conclusions from this curve impracticable. It is 

 probable that the maximum starch content of this variety was attained 

 on July 2, the same date as in the case of the Yellow Transparent. On 

 two subsequent occasions, however (July 22 and 29), a higher content 

 of starch was noted, but on each of these dates the content of sucrose
