that of a heavy shandy loam. It is seldom that the stones in the 

 soil are numerous enough to interfere with cultivation. The sur- 

 face is, on the whole, flat or gently rolUng. The soil is known 

 locally as the "barrens." It varies considerably in productive- 

 ness, hni at best the yields are low. Corn gives from 10 to 15 

 bushels, and cotton about one-fourth bale per acre. Truck and 

 fruit are also grown to some extent.
