HUMPBACK WHEAT. 3 



hard spring wheats. Attention is culled to the fact that the results 

 ion the Humpback wheat, as shown in the -table, include tests of sam- 

 ples representing the crops of the three years, 1908, 1909, and 1910. 

 The crops of 1908 and 1909 are represented by one sample each, and 

 the crop of 1910 by nine samples. Five of the samples of the L910 

 crop were secured near Hoffman, Minn., and the remaining four from 

 near Kensington, Minn. At each of these points a sample of Blue- 

 stem wheat was also obtained, the results of milling and baking tests 

 upon the same being likewise shown in Table I. The figures at the 

 bottom of the table give the average of tests of Bluestem and Velvet 

 Chaff wheats from North Dakota and Minnesota of the 1910 crop and 

 afford an interesting comparison with the Humpback wheat, to the 

 disadvantage of the latter. With the exception of samples 255 and 

 502, the results as given in the table are based on the yield of "straight 

 flour," the tests on these two samples being on the patent flour.

1 With samples 255 and 502 the tests were made on the patent flour, but in all other cases on the straight 

 flour. 



From the standpoint of flour yield, as obtained upon the experi- 

 mental mill of the North Dakota Agricultural Experiment Station, 

 it will be noticed that the Humpback wheat, like other large-berried 

 varieties, gives a high yield of flour, in this respect probably excel-
