UNION COUNTY. 219 
New London Landing, on Ouachita River, overlie the lignite ex- 
posed in the river bluff at those places. This clay, however, is not 
everywhere valuable. 
CLAY DEPOSITS. 
In the neighborhood of Beach Creek, where it is crossed by the 
Mount Holly-Lisbon road, many small fragments of fine potter's 
clay are scattered through the sandy clays. These fragments are of 
no value in themselves, but their presence suggests the probability 
that they were derived from deposits of fine potter's clays in this 
neighborhood. Similar evidence of the presence of good clays are 
common at many points in both Union and Columbia counties. 
About Lisbon such clays are exposed in deep gullies, especially on 
the west side of the town, near Camp Creek, and also on Holmes 
Creek. 
About 2 miles west of Lisbon, on the Lisbon-Mount Holly road, 
just west of the Rose farm, on the brow of a westward-sloping hill, 
3 or 4 feet of dove-colored potter's clay is exposed by the roadside. 
The total depth of the bed, however, is not visible. In places this 
bed contains very thin laminae of fine sand, which may prove injurious. 
East of Lisbon the clays and sands are thinly laminated and inter- 
stratified, so that they are not available for the manufacture of pot- 
tery or fire-clay products. 
Four miles west of Eldorado, on the road to Lisbon, there are some 
rather promising looking exposures, but so far as examined they 
contain too many streaks of sand to be useful. Further search in 
the vicinity is likely to discover good beds. 
One and one-fifth miles west of Eldorado, on the Lisbon road, on 
the side of a hill facing westward, the following section is exposed: 
Section near Eldorado. 
Yellow soil and clay at surface. Ft. in. 
Good pink clay with fossil leaves 1 
Gray, rather sandy potter's clay 4 
Pink sandy clay 8 
Dull pink sands exposed 2 
The clays exposed by the Eldorado-Lisbon road, about 400 feet 
west of the first milepost west of Eldorado, are all or nearly all too 
sandy to be available for the manufacture of pottery. 
Three miles east of Eldorado the road to Wilmington Landing 
passes over a bed of pink potter's clay containing abundant leaf 
impressions. On the south side of the road the bed is about I feet 
thick, but it is not exposed on the north side of the road. 
About 1} miles southwest of Wilmington Landing, on the edge of 
the flat woods, some fair pottery clays are exposed by the roadside, 
but their thickness is not evident.
