very broken country, consisting of hills, ridges, and intervening 

 valleys. Owing to the stony character of this soil and the unfa- 

 vorable surface features, but little of it is under cultivation. On 

 steep slopes erosion does much damage, and only on the more 

 level areas can the cultivation of the type be recommended. The 

 soil is derived from the Knox dolomite, a limestone rock contain- 

 ing a large quantity of difficultly soluble material known as chert. 

 The native growth is Spanish and black-jack oak, pine, and chest- 

 nut. Cotton, corn, and some wheat are grown, but tlie yields 

 are light. The soil is best adapted to fruit, and especially to 

 peaches.
