The hornblendic soils are a variety of these red clay soils, derived from 

 granite and gneiss rock, traversed by seams of hornblende. They are 

 dark in color, and of a more brilliant red. They occur in Edgefield, 

 about Horn's creek, and most extensively in Newberry, especially between 

 the Court House and Asheford's ferry, extending thence into Fairfield. 

 They form excellent cotton lands^ and are well suited to the culture of 

 all the grains. The following analyses of them are from Tuomey :
