EFFECT OF EARLY FREEZING ON VARIETIES, 1915 
On October 10, corn was gathered from twenty-seven differ- 
ent varieties and hybrids for moisture and germination tests. 
These varieties and hybrids represented many different stages 
of maturity at the time the frost came. Some were late varieties 
and were still very immature, while others were early and were 
comparatively dry. Intermediate stages were also represented. 
The moisture content of the grain and also of the cob at the 
time of harvest . together with the germination for each variety, 
is shown in Table 22. It will be noted from this table that 
the moisture content of the grain was still rather large for 
most varieties. The germination tests, however, are so nearly 
perfect for all. that it seems hardly possible to tiace any. injury 
back to the effect of the frost.

maturity and gathered on October 10, after the first killing 
frost in 1915. The degree of maturity is indicated by the 
per cent of moisture in the cob and in the grain 1
