Penn Series. 87 



Penn gravelly loam. — A dark-red or brown sandy loam, 8 to 10 

 inches deep, of medium texture, containing from 10 to 60 per cent 

 of small, rounded sandstone gravel. The subsoil is a dark Indian- 

 red loam or clay loam. Occurs as high, rolling upland. The 

 drainage is good, but the soil is inclined to ^vash badly. Derived 

 generally from the Triassic' red sandstone. Produces fair yields 

 of corn, wheat, vegetables, and small fruit.

 surface varies from rolling to moderately hilly land. It is easily 

 tilled. Crops are of good ({uality, but light yield.

Penn loam. — Is a dark Indian-red loam, 8 to 12 inches deep, 

 underlain by Indian-red clay loam subsoil. Occasionally con- 

 tains 5 to 20 per cent of sandstone fragments. Surface gently 

 rolling. Derived from fine-grained brown or red sandstone (Tri- 

 assic). The drainage is fair, but plowing in beds is generally 

 practiced to assist the natural drainage. It is considered almost 

 equal to associated limestone soils in fertility.
