DALHART FIELD STATION. 
The soil at the field station at Dalhart, Tex., is a sandy loam. 
In some respects it behaves like sand. In other respects it exhibits 
the characteristics of heavy clay soil. Its water-holding capacity 
is comparatively limited. The crops appear, however, to be able to 
utilize its water to the depth of a normal development.
