30 per cent. When grown under unfavorable conditions, 

 the percentage of hull is relatively high, while favor-, 

 able conditions for 

 growth produce 

 short, plump grains, 

 with a relatively low 

 percentage of hull. 

 The size, shape, and 

 color of the grain 

 vary with the con- 

 ditions of growth, 

 and with the vari- 

 ety. The most com- 

 mon colors are white 

 and yellow, although 

 quite a few varieties 

 are black, gray, or 

 red in color. The 

 legal weight per 

 bushel in most states 

 is 32 pounds. How- 

 ever, the weight per 

 measured bushel 

 varies with the va- 

 riety, the season, and 

 the time of cutting, 

 and due to these 

 factors, will some- 

 times show a range 

 of from 20 to 50 

 pounds per bushel. 

 " Clipped oats " is a market term employed to define oats 

 that have had a part of the hull clipped off by machinery
