AMERICAN WHEAT AND CORN. 19 



The red varieties and the bearded wheats seem to possess a trifling 

 advantage in Ohio, at least for the years during which the experiments 

 were carried on. 



MINNESOTA. 



The specimens previously analyzed from this State were from the ex- 

 hibits of the Saint Paul, Minneapolis and Manitoba Railroad in the De- 

 partment Museum, but as they were not considered representative 

 wheats by prominent millers, and the results were unsatisfactory to 

 them, they were invited to send samples of their own selection from the 

 crop of 1883. The analyses given in this bulletin will, therefore, show 

 the composition of the best spring wheat of Minnesota, but it can hardly 

 be said to represent the average of the State, as the samples were all 

 of No. 1 hard wheat. 



The average of the analyses previously published, of the four made 

 this year and of all taken together, are given below : 



The average of all probably fairly represents the production of the 

 State, while " No. 1 hard spring wheat 7 ' is richer in albuminoids, but 

 small in size, both of which characteristics may be due to a lack of 

 starch, owing to the short period of growth and rapid maturity and 

 consequent inability to assimilate as much of the carbohydrates as the 

 winter wheats. 



This point is well illustrated by two wheats from Dakota, analyses 

 of which were published in our previous report, one of which was a 

 winter wheat and the other spring. The weights of one hundred grains 

 were 



Grams. 



Winter 3. 513 



Spring 2. 75o 



and the percentages of albuminoids 



Winter 10. 68 



Spring 14.35 



the latter being in inverse proportion to the former, so that if the 

 winter wheat were supposed to be diminished in size at the expense of 

 its starch the relative percentage of nitrogen would rise to a point near 

 that usually found in spring wheats. 



In another portion of this report the flours and mill products from 

 the spring wheats of Minnesota will be discussed.
