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 apples after the date mentioned. This growth 

 of the apples after July 2 amounted, in the case of the Early Straw- 

 berry apple, to 29 grams, the weight increasing from 43 grams on 

 July 2 to 72 grams on August 5.
