ture for the growing season from February to October, inclusive, for 

 the years 1909, 1910, and 1911; also the mean temperature for the 

 month and the departure from normal. 



Table LVII is a summary of Table LVI and shows that in 1909 

 one month was normal, two were above normal, while the remaining 

 six of the growing season were below normal. The total accumulated 

 mean temperature for the 1909 growing season was 15.9° below the 

 normal, giving an average monthly departure from the normal of 

 -1.76°. 



The 1910 season shows four months above the normal and five 

 below, with a total accumulated mean temperature for the growing 

 season of 7.9 below normal, with an average monthly departure from 

 the normal of —0.87°. 



The 1911 season shows one month above the normal and the 

 remaining eight below, witli a total accumulated mean temperature 

 of 23.7° below normal for the growing season, which gives an average 

 monthly departure from normal of —2.63°. 



The 1910 season was much the warmest and 1911 unusually cold — 

 so much so that most stone fruits did not sugar up well. The 1910 

 season, barring June, which was very cold, was practically a normal 

 growing season. 



Looking at the three seasons from a meteorological point of view, 

 one should expect to find the largest percentage of the first-brood 

 larvae transforming in 1910, with a large second brood indicated by 

 the band record, while 1911 should give the smallest percentage of 

 transforming first-brood larva 3 , with a smaller second brood indi- 

 cated by the band record. The 1909 season should have given a 

 larger percentage of transforming first-brood larvae than 1911 but 

 less than 1910 and a larger second brood than the 1911 and a smaller 

 one than the 1910 season. 



Just what did happen is given under that paragraph comparing 

 the seasonal history of the three years.
