kernels, and (2) to include the ordinary sorts of commercial corn 
containing not more than 5 to 6 per cent of field-damaged kernels 
(commercial basis, heat-damaged or "mahogany" kernels excluded)," 
regardless of the moisture content of the corn, that each of the 
suggested classes be subdivided into grades based upon the mois- 
ture content of the corn, that no one grade should contain a greater 
range than 2 per cent of moisture, 6 and that no corn should be 
graded, shipped long distances, put into storage, or exported on 
grades unless it be commercially clean and free from indications of 
fermentation. 
The necessity for some arrangement of this kind in the grading of 
corn and for more care in the methods of handling corn becomes more 
apparent as the prices and values of grain continue to increase, and 
as they continue to increase the advisability of still narrower limits 
of moisture within the grades will become more apparent.

a The analyses of samples taken from various cargoes of corn, representing approxi- 
mately A\ million bushels of all grades exported from the United States during No- 
vember and December, 1908, and February, March, April, and October, 1909, showed 
a maximum of 10.2 per cent (December, 1908), a minimum of 2 per cent, and an aver- 
age of about 2.5 per cent of field and mold damaged kernels. The maximum of 10.2 
per cent was unusual and undesirable. It is the opinion of the writers that corn 
containing more than 5 to 6 per cent of such damaged kernels and also corn containing 
heat-damaged or "mahogany" kernels, should be bought and sold "on samples" or 
on special grades. . 
ft Bulletin 99, Bureau of Plant Industry, U. S. Dept. of Agriculture, describes the 
Brown and Duvel apparatus for and method of making moisture determinations in 
grain quickly. The apparatus has been recommended by the Department of Agri- 
culture and is extensively used in the grain trade for the purpose.
