EFFECT OF FIRST KILLING FROST ON VARIETIES, 1917 
The test with corn varieties and hybrids reported in 
Table 22 for 1015, was repeated in 1017. Types varying widely 
as to earliness and related moisture content were represented. 
An unusually large amount of moisture was present at the time 
of the first killing frost on October 8. Ten ears of each variety 
and hybrid were gathered the following day and tested for 
moisture and germination. The results are given in Table 27. 
The varieties and their hybrids represented many different 
stages of maturity at the time they were gathered for testing. 
The grain varied from 16 to 47 per cent moisture content, 
according to variety. The germination tests show very little 
injury from this first frost, even for the late maturing varieties. 
Table 27 — Germination of corn varying in degree of maturity 
and gathered after the first hilling frost on October 8 , 1915. 
The degree of maturity is indicated by the per rent of 
moisture in the grain.
