Note. — The soils of Chewaucan Valley range from a very fine, sandy loam to a very stiff, silty clay 
which is hard to work and of low water-holding capacity. The lighter soils, however, are productive, 
easily worked and of good water-holding capacity. 
The soils of the Harney Valley are varied but silt predominates, being about 4 to 6 feet deep, with a sandy 
subsoil, and are easily worked, also grow excellent crops. 
The crops grown in these valleys are hay and grain.
