high-yielding sorts in the same general regions, Hannchen yielding better in 
years when there is more than the average rainfall and White Smyrna when there 
is less. 
Odessa (C. I. No. 927) and the barleys of the Manchuria type were not tested 
for more than three years, as none of them is adapted to growing conditions in 
these arid regions. Horn (C. I. No. 926), a Chevalier variety with an average 
yield of 105 per cent of the weighted mean for the years 1914 to 1917, inclusive, 
was exceeded by the other 2-rowed varieties grown those years. Baker (C. I. 
No. 975) was introduced into the experiment in 1918 and was continued through 
1921. This is also a pedigreed variety which was originally selected from the 
same bulk im.portation as Trebi. It has not proved so good at this station, 
however, as Trebi. 
While the irrigated lands in southern Idaho are well adapted to the growing of 
barle3^s of the Coast type, such as Beldi Giant and Sandrel, and to the 2-rowed 
variety Hannchen, in nearly all of the places where Trebi has been grown it has 
proved superior to them. 
Dry-land conditions. — Barley varieties were grown on dry land at the Aberdeen 
(Idaho) substation during the period from 1913 to 1918, inclusive. These yields, 
shown in Table 68, were obtained in cooperation with the Idaho Agricultural 
Experiment Station. Only two varieties were grown during the full period of 
the experiments. They v.^ere White Smyrna (C. I. No. 195) and Club Mariout 
(C. I. No. 261). These produced an average yield of 20.7 and 20.5 bushels, 
respectively, for the six years, so that they are essentially equal. Winter Club 
(C. I. No. 592) was grown from 1913 to 1916, inclusive, but was inferior to most 
of the spring barleys grown in those years. Although Hannchen (C. I. No. 531) 
was not grown in 1914, in the five years in which it was comparable it did not 
prove so good as White Smyrna or Club Mariout. Coast (C. I. No. 690) produced 
fairly good yields in 1913 and 1914, but was very poor in 1915 and consequently 
was dropped from the experiment the following year. Svanhals (C. I. No. 187) 
was grown for this same period, but is evidently not adapted to dry-farming 
conditions in southern Idaho.

Winter was contirmed in the experiment through 1917. Turkestan (C. I. No.
