Such local type differences within a variety may be illus- 
trated by Table 3, which shows the comparative growth habits 
of typical Lancaster County and Thurston County Reid’s Yel- 
low Dent corn when grown comparably at the Experiment Sta- 
tion in Lancaster County. The northern seed obtained from one 
hundred miles farther north matured a week earlier and the 
plants were distinctly shorter and lighter weight, the ears were 
smaller and the kernels shorter and smoother, and the shelling 
percentage and shrinkage of ear corn were also somewhat less.

1 The first ten characters are the composite data for three field plats of 
600 plants. The other measurements are bas?d on ten representative successive 
plants for each plat. 1916 was a fairly normal year for corn.
