cultural Experiment Station and to Sherman County for their share 
in obtaining the cooperative results reported in this publication. 
Some preliminary work was done in 1910, but most of the experi- 
ments were not started until 1911. The investigational work at 
Moro comprises tests of methods of production and improvement of 
cereals, including crop rotation and tillage. This bulletin deals only 
with the varietal tests of spring-sown cereals, including wheat, 
emmer, oats, barley, and grain sorghums. 
DESCRIPTION OF THE STATION. 
The Eastern Oregon Dry-Farming Substation is located in the 
southwestern part of the Columbia Basin, 1 near Moro, in Sherman 
County, Oreg. Eastern Oregon, as the term is used locally, refers to 
all that portion of the State east of the Cascade Mountains. Sherman 
County lies along the Columbia River, the northern border of the State. 
It is really about midway of the State from east to west. Moro is

about 15 miles from the Columbia River, on a branch line of the 
Oregon- Washington Railroad & Navigation Co. A map of the State, 
on which the location of the substation is indicated, is shown in 
figure 2. 
The elevation of the substation is approximately 2,000 feet. The 
soil and climatic conditions at Moro are typical of a large part of the 
Columbia Basin. It is believed, therefore, that the results obtained 
at the substation are applicable in a general way to most of the 
Columbia Basin, but especially to districts where the prevailing soil 
type is silt loam and where the annual average precipitation ranges 
from 9 to 12 inches. 
The substation comprises 233 acres, about 200 of which are till- 
able. Like most of the Columbia Basin lands, the surface is very 
rolling, nearly every direction and inclination of slope being repre- 
sented. On the experimental plats the slopes vary from nearly level
