on the cost of production, but the Hannchen (S. Dak. No. 20, C. I. 
No. 531) and the Bohemian (S. Dak. No. 27, C. I. No. 27) have 
returned a profit of 11 per cent. The profit obtained from these 
selected varieties shows the value of pure strains of superior merit. 
At Eureka the best yielding variety, the Hannchen, has been grown 
at an average loss of 15 per cent for the four years from 1909 to 
1912, and the three varieties tested have been produced at an average 
loss of about 33 per cent. The two varieties grown at Cottonwood 
returned only about 10 per cent of the cost of production during the 
four years of the test. For the entire State the average production 
was 22.3 bushels for the eight years (Table XIV), or 6.3 bushels 
more than the equivalent of the estimated cost of production (16 
bushels). This is a profit of about 40 per cent.

From a commercial standpoint the growing of pure varieties is of 
even greater importance in the production of barley than of oats or
