Cardiff slate loam. — Heavy yellowish-brown loam, having a depth 

 of 8 or 10 inches, underlain by heavy yellow silty clay to a depth 

 of 3 feet or more. Both soil and subsoil contain from 15 to 40 per 

 cent of partially decomposed slate fragments. Formation occurs 

 on prominent narrow ridges. Derived from the decomposition 

 and breaking up of fine-grained slate. The presence of the slate 

 fragments in the soil makes quite friable what would otherwise be 

 a refractory clay. iNIuch of the area is forested with oak, chest- 

 nut, and other trees. Produces fair crops of corn, wheat, rye, 



oats, and grass.

Conowingo barrens. — Loam 3 feet or more in depth, frequently 

 filled with fragments of broken rock, increasing in size and amount 

 in lower depths; often there is no soil covering over the broken 

 fragments of rock. Rolling upland of Piedmont Plateau. Derived 

 from decomposition of serpentine and rocks of similar nature. 

 Generally unproductive and frequently worthless for agricultural 

 purposes, owing to slight depth of soil covering, but usually ascribed 

 to preponderance of magnesia.
