370 DRY-FARMING 
Station is investigating the problems of dry-farming 
peculiar to the Columbia Basin, and the staff of 
the Oregon Station is carrying on similar work. In 
Nebraska, some very important experiments on dry- 
farming are being conducted. In North Dakota 
there were in 1910 twenty-one dry-farm demon- 
stration farms. In South Dakota, Kansas, and 
Texas, provisions are similarly made for dry-farm 
investigations. In fact, up and down the Great 
Plains area there are stations maintained by the 
state or Federal government for the purpose of deter- 
mining the methods under which crops can be pro- 
duced without irrigation. 
At the head of the Great Plains area at Saskatch- 
ewan one of the oldest dry-farm stations in America 
is located (since 1888). In Russia several stations 
are devoted very largely to the problems of dry 
land agriculture. To be especially mentioned for 
the excellence of the work done are the stations at 
Odessa, Cherson, and Poltava. This last-named 
Station has been established since 1886. 
In connection with the work done by the experi- 
ment stations should be mentioned the assistance 
given by the railroads. Many of the railroads own- 
ing land along their respective lines are greatly 
benefited in the selling of these lands by a knowl- 
edge of the methods whereby the lands may be 
made productive. However, the railroads depend 
chiefly for their success upon the increased prosperity
