GRADKS FOR (M)MMRRCTAL CORN. 11 
im- 
colors, as nearly as it is p()ssil)l(\ t.o roproduco tlicin. Kernels nui 
bered 1 to 9, inclusive, under ty])es of color, have been classified as 
white corn. It will be noted that some of the kernels at the right in 
this first series are of a very light straw color, but not sufficient to 
justify their being classed as of other colors when found in a grade 
of white corn. Kernels with a tinge of pink over white (not shown 
in the plate) should be considered on the same basis as straw-colored 
kernels; that is, where the pink color is only very slight they may be 
classed as white; otherwise they should be eliminated. In kernel 
No. 10, however, the yellow color is more pronounced, and such ker- 
nels should not be classed as either white or yellow corn. The same 
is true with all kernels numbered 10 to 18, inclusive. Kernels num- 
bered 10 to 14, inclusive, are intended to represent white-capped 
pale yellow, kernel ISTo. 19 represents a pale yellow of the lowest 
type, and kernel No. 27 represents a ^'red-cast" yellow of the most 
pronounced type which should be classed as yellow corn.
