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.
