The average yields of the eight varieties are shown graphically 
in figure 12. 
The White Smyrna (Ouchac, C. I. No. 658), a 2-rowed hulled 
variety, has given the highest annual and average yields. The 
Hannchen (C. I. No. 531), also a 2-rowed variety, has yielded well. 
In the 6-rowed hulled group, the Coast (C. I. No. 690) has been the 
highest yielding variety, with the Manchuria (Minn. No. 6, C. I 
No. 638) second. In the 6-rowed naked group, the Black Hull-less 
(C. I. No. 1106) has yielded quite well. There has been less than

1 bushel difference in the yields of the White Smyrna and the Coast, 
the two leading varieties. The Hannchen has also yielded well, 
since the yields here presented are averages from several check 
plats of this variety in 1913 and 1914. 
RATE-OF-SEEDING EXPERIMENT. 
A rate-of-seeding experiment with the Svanhals barley has been 
conducted at the Cheyenne Experiment Farm during the 3-year 
period, 1913 to 1915, inclusive. In 1913, plats were sown at the 
rates of 2, 3, 4, and 5 pecks per acre. In 1914 and 1915 sowings 
were made at the rates of 2, 3, 4, 5, 6, and 7 pecks. The annual and 
average yields obtained in the rate-of-seeding tests are shown in 
Table XXII.
