than in the check test with clean wheat, and the percentage of the 

 lower grades of flours was correspondingly increased. This fact is of 

 great importance in placing a valuation on wheat which contains any 

 considerable amount of these objectionable impurities', for a reduction 

 in the/yield of high-grade flour that can be obtained is a financial loss 

 to the miller, and the grade of such wheat should be lowered according 

 to the percentage of admixture of the impurity.
