From the temperatures presented in Table 1 and from the 

 average temperatures for the growing season shown in Table 3, 

 it is apparent that the average temperature at the Arlington Ex- 

 periment Farm at Rosslyn, Va., was about 6° F. above that at 

 Amherst, Mass., and East Lansing, Mich., during 1923. Wooster, 

 Ohio, and Council Bluffs, Iow T a, were intermediate in temperatures, 

 the latter being almost as warm as Rosslyn. 



The 1924 growing-season temperatures averaged somewhat cooler 

 throughout the Eastern States, with less variation in the different 

 districts then in 1923. Mean temperatures for the full growing 

 season at Wenatchee during 1924 averaged slightly warmer than 

 at Amherst, Wooster, and Ithaca, and somewhat cooler than 

 Rosslyn and Council Bluffs. The daily fluctuation at Wenatchee is 

 greater than at any other station studied ; the mean temperature was 

 intermediate, but the daily maximum averaged higher and the daily 

 minimum lower than at the other stations. 



INCREASE IN SIZE OF FRUIT 



The exact increase in the size of apples during the latter part of the 

 growing season, and particularly through and following the normal 

 picking season, has not heretofore been extensively studied. White- 

 house (19) determined the rate of growth of Grimes Golden apples 

 in western Oregon from June until September 20 and found that 

 the increase in diameter proceeded at a fairly constant rate. 

 Magness and Diehl (11) showed that Winesap apples at Rosslyn, 

 Va., were still growing rapidly on October 10 during the season of 

 1919. The rates of increase in size of the fruit of the different
