mum percentages of moistm-e allowed are 13.5, 14, lo, 15.5, 

 and 15.5, respectively. The percentages of foreign material 

 other than dockage are 1, 2, 3, 5, and 7, of which H, 1, 2, 

 3, and 5 per cent may be matter other than cereal grains. 

 Likewise, the allowable percentages of damaged kernels, 

 heat damaged kernels, and of other wheats increase rela- 

 tively through the different grades. Sample wheat of any 

 of these subclasses is wheat that does not come within the 

 requirements of any of the grades, has an objectionable for- 

 eign odor, is sour or heating, or is otherwise of low quality. 



The requirements for the different grades in other sub- 

 classes are similar to those just given, though the weights 

 and percentages for the same grade (No. 1, for instance) in 

 the various classes are not necessarily the same. The full 

 descriptions of the 84 grades occupy 21 pages in the bulletin 

 in which they were originally published. i
