(21) York silt loam, Bethany, S. C, f mile east of Kings Mountain 

 battleground. Depth to 10 inches. This soil is derived from im- 

 perfectly crystalline rocks, consisting mostly of talcose and micaceous 

 schists. It belongs to the Piedmont Plateau province. In appear- 

 ance it is an almost white silty loam full of small spangles of mica. 

 The spot from which this sample was taken supports a virgin growth 

 of shortleaf pine and red oak. Nearby fields were in poor condition 

 and the type is markedly infertile. This sample contained 7.6 per 

 cent stones. Of this amount 59 per cent was quartz and 41 per cent 

 was mica schist. 



(22) York silt loam, subsoil of No. 21, depth 10 to 22 inches. This 

 sample contained 8 per cent of stones. Sixty per cent was quartz and 

 40 per cent mica schist. The mica schist particles had largely disin- 

 tegrated and fell to pieces when washed with water. 



(23) Louisa loam, 1£ miles southeast of Trevilians, Va. Depth 

 to 12 inches. This type belongs to the Piedmont, and is formed from 

 talcose and micaceous schists and imperfectly crystalline slates. It 

 is a friable pale-yellow loam. The sample was taken from a wood- 

 land, principally of Spanish and red oak. Nearby fields supported 

 scant crops, and the fertility would be considered low. This sample
