Soils of the Talcose Slates. 
These are certainly the poorest soils in the upper country. They are found in the gold regions of 
the State, but it will be recollected that gold is found in other rocks that must not be confounded 
with these slates. The following are analyses of these soils from the gold bearing rocks of Lancas- 
ter. No. 1, from the vicinity of the mines South East of the village, and No. 2 is from the Northern 
part of the District, both cultivated soils. 
No. 1. No. 2.

Soils of the Clay Slates. 
The soils of these rocks border the Tertiary through its entire extent on the North, and cover a 
considerable area on Stevens’ Creek, in Edgefield. They are poor and thin, and when worn out, are 
reclaimed with difficulty; they do not, however, suffer to the same extent from retentiveness, as simi- 
lar soils do that rest on horizontal rocks. 'The slates being highly inclined, and much fissured, al- 
low the water to pass off freely. 
Where the slates are not too much intersected by quartz veins, they form the basis of a soil that 
with good management may be rendered productive. I saw some good farms on these rocks near 
Mr. Crogan’s, Chesterfield, where they contain less silica, and where, instead of being gray, like the 
Edgefield soils, they are red. 
No. 1, is from Stevens’ Creek, Edgefield; No. 3 froma field North of Columbia, and No. 2 from 
Lexington, near the Saluda.
