1906. During the following two weeks no rain fell, the next rains 

 being recorded when the corn was edible (1 inch) and during the har- 

 vesting period (0.15 inch). The sugar content for this year exceeds 

 that of 1906 by 5 and 10 per cent for the Crosby and Stowell Ever- 

 green, respectively, and is greater than the figures for 1908 by 5 and 

 \ per cent. 



Frequent light rains are recorded for 1908, two rains with a total 

 precipitation of 0.7 inch on the second and third day after tasseling, 

 and daily rain< from the twelfth to the fifteenth day, inclusive, with 

 t he same small total precipitation. No further rainfall occurred until 

 harvest time, when t here was a precipitation of 2.15 inches, distributed

over live -un>ecutive days. For the entire four weeks preceding the 

 IOD "t harvest six rains are recorded and 1.4 inches of rainfall. 

 Fnm these data it would appear that excessive rainfall during 

 the first two weeks after tasseling interferes decidedly with the 

 storage of sugars, while the very light rainfall during the following 

 t\\o weeks represented almost ideal conditions. The undesirable 

 conditions of 1906 are obvious, while 1907 and 1908 differ but little 

 in total amount of rain (11.66 and 12.55 inches, respectively), both 

 being less than the total for 1906 by about 10 inches. The supe- 

 riority of the conditions of 1907 over 1908 was almost entirely due 

 to distribution, as in 1907 the heavier rains fell during the first two 

 \\eeks of growth, when needed most, while there was very little 

 rain in 1908 during that period. The effect of the distribution and
