A STUDY OF SHELLED CORN 103 



No. 4. , White Corn. Shall be fifteen-sixteenths white, 

 but shall include tough, musty, and damaged corn. 



(Mixed corn and yellow corn have separate rules, but 

 the rules are the same other than color. In yellow, seven- 

 eighths is used instead of fifteen-sixteenths, as in white.) 



The per cent of moisture contained in corn affects its 

 quality. Corn with a high per cent of moisture is usually 

 tough and is given a lower grade. 



Corn to grade No. 1 is not allowed to have over 15 

 per cent of moisture ; to grade No. 2 not over 16 per cent ; 

 to grade No. 3 not over 19 per cent; to grade No. 4 not 

 over 22 per cent. 



Make a study of as many samples as the time given per- 

 mits.
