The wheat used in the experiment was thoroughly cleaned andscoured before making up the milling samples containing the variousadmixtures of rye, corn cockle, kinghead, and hairy vetch. This wasdone because the samples were neither cleaned nor scoured after themixing, since it was desired that a definite known percentage of anyadded impurity should go to the rolls for milling into flour, bran, andshorts. Each sample milled consisted of 100 pounds, including the impurity(e. g., 99 pounds of wheat and 1 pound of corn-cockle seed; 98 poundsof wheat and 2 pounds of corn cockle seed, etc.). The samples were. Fig. 1.—Grains of rye (A) and wheat (B); seeds of corn cockle ( C), hairy vetch (D), kinghead (JE), andwild vetch (F). On account of the shape, size, and specific gravity of these impurities they are noteasily separated from wheat. (Natural size.) milled at the North Dakota Agricultural College in the experimentalmill, which has a capacity of 50 barrels per day of 24 hours. To obtain results which would be comparable with average com-mercial conditions at country points, the methods of milling used incountry mills were followed in general in the tests with the so-calledinseparable impurities. The flour yields obtained compare very favor-ably with those secured by well-equipped country mills of 50 to 100barrels daily capacity, since it was possible in milling the samples tomake five breaks and as many reductions as desired, up to seven oreight.
