that the differentiation of prices between the grades was unjustly great
and out of proportion to the actual difference of value. In order to ascertain whether this was the case or not, the Farmers' Association of Blue Earth County, Minn., decided to have samples of each grade analyzed by a competent chemist in order to determine their relative value. Accordingly specimens were secured, certified to by the agent of the Millers' Association of Minneapolis, and sent to the University of Minnesota for analysis. The analysis was conducted by Prof. Wm. A. Noyes, Ph.D., an experienced chemist, who has recently reported as follows: "The analyses of wheat given below were undertaken for the purpose of determining whether the millers' grades of wheat correspond to an actual difference in the chemical character of the wheat. For this purpose samples of wheat were secured, which were inspected and certified to by M. W. Trexa on April 13th of this year. The inspection cards contained no statement except the grade of the wheat and the weight per bushel, but the samples were all of Fife, for the purpose of a better comparison. The analyses of the wheat were made during October in this laboratory. In each case the wheat was carefully separated from any foreign substances before analysis. The results of analysis were as follows: Grade Grade Grade No. 1. No. 2. No. 3. Weight per bushel.................. 59 lb. 56½ lb. 55 lb. Grains to weigh 10 grains.......... 366 474 491 Per ct. Per ct. Per ct. Foreign matter (seeds, etc.)....... 0.41 0.20 1.57 Nitrogen........................... 2.09 2.08 2.17 |
