MISCELLANEOUS SOILS OF THE PIEDMONT PLATEAU. 



Loudoun sandy loam. — A heavy brown or gray sandy loam 8 to 10 

 inches deep, underlain by a heavy yellow or red loam or clay loam. 

 There is a considerable variation in the subsoil, coarse sand often 

 forming so large a proportion as to give it almost the texture of 

 the soil. The surface material is not a loose sandy loam, but has 

 the properties of a loam, containing, however, considerable quan- 

 tities of coarse quartz fragments. The soil resembles in some 

 respects the Cecil sandy loam and Cecil loam with which it is asso- 

 ciated. Occurs in rolling and somewhat hilly areas, generally 

 well drained. Derived from the weathering of a coarse-textured 

 schist and an eruptive crystalline granite, the original rock con- 

 taining a large amount of feldspar. Good soil for corn, yielding 

 from 40 to 50 bushels per acre. It is too little retentive of moisture 

 for wheat, which produces only from 10 to 15 bushels. It is a 

 fairly good soil for grass and clover.
