of invert sugar than starch and.the percentage of invert sugar 
increased steadily until the sample was examined on July 4. Later 
the percentage of invert sugar decreased. This does not mean, how- 
ever, that an actual loss of invert sugar is indicated, as will be seen 
by consulting figure 21, in which the composition of the fruit in grams

per apple is given. The reason for the apparent loss of invert sugar—- 
that is, for the decrease in the percentage of invert sugar—is due to 
the rapid growth of the seh s after the date mentioned. This growth 
of the apples after July 2 amounted, in the case of the Karly Straw- 
berry apple, to 29 grams, the weight increasing from 43 grams on 
July 2 to 72 grams on August 5.
