classes; the hard red wmter class into dark hard, hard, and 

 yellow hard winter subclasses; the soft red winter class into 

 red winter and red walla subclasses; and the common white 

 class into hard white and soft white subclasses. Each of 

 these subclasses is then divided into six grades, No. 1, No. 2, 

 No. 3, No. 4, No. 5, and Sample. The full descriptions of 

 the grades in one class will be sufficient illustration of the 

 differences between the various grades. 



Class III. Hard Red Winter, shall include all varieties of hard 

 red winter wheat, and may not include more than 10 per cent of other 

 wheat or wheats. This class shall be divided into three subclasses a? 

 follows : 



Dark Hard Winter. Tliis subclass shall include wheat of the 

 class Dark Red Winter consisting of 80 per cent or more of dark, hard, 

 and vitreous kernels. 



Hard Winter. This subclass shall include wheat of the clasp 

 Hard Red Winter consisting of less than 80 per cent and more than 

 25 per cent of dark, hard, and vitreous kernels. 



Yellow Hard Winter. This subclass shall include wheat of the 

 class Hard Red Winter consisting of not more than 2.5 per cent of 

 dark, hard, and vitreous kernels. 



No. 1 wheat of each of these subclasses (a) shall be bright, cool, 

 and sweet; (b) shall have a test weight per bushel of at least 60 pounds; 

 (c) may contain not more than 13.5 per cent of moisture; (d) may con- 

 tain not more than 1 per cent of foreign material other than dockage, 

 which 1 per cent may include not more than one half per cent of mat- 

 ter other than cereal grains; (e) may contain not more than 2 per 

 cent of damaged kernels, which may include not more than one tenth 

 of 1 per cent of heat damaged kernels; and (f) maj^ contain not more 

 than 5 per cent of wheat other than hard red winter, which 5 per cent 

 may include not more than 2 per cent of common white, white club, 

 and durum wheat, either singly or in combination. 



The lower grades of dark hard winter, hard winter, and 

 yellow hard winter wheat differ from No. 1 just described in 

 having (1) a lower bushel weight, (2) a higher percentage of 

 moisture, (3) a higher percentage of foreign material, (4) 

 and a higher percentage of damaged kernels. The minimum 

 bushel weights for the five grades (Nos. 1, 2, 3, 4, and 5) 

 are 60, 58, 56, 54, and 51 pounds, respectively. The maxi-
