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. 561/2 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
