4S THE CLAYS OF ARKANSAS. 
ASHLEY COUNTY. 
The locks all through the higher parts of the county belong to the 
Eocene (Tertiary). The lowlands along Saline River, on the west 
and east of Overflow Creek, and along Bayou Bartholomew are 
mostly alluvia] lands, where only brick clays maybe looked for; or 
they arc "-slashes," where occasional pockets or thin beds of common 
pottery clays may be found. 
The beds of the higher portions of the county are nearly horizontal 
and consist, for the most part, of sands .and clays in various combina- 
tions and occasional beds of lignite. 
The well sunk at the court-house at Hamburg is said to have 
passed through the following section : 
Section in well at Hamburg. 
Feet. 
Sandy soil 3-4 
Not recorded 23 
White pipe clay 10 
Red clay 3-6 
White quartz sand 20 
Pebble bed. 
The pipe clay of this well section suggests that valuable clays 
may be found at some places in Ashley County, probably on slopes 
where the streams have cut deep into the soil. They will probably 
be found also in the deep wells. 
G. D. Harris, while working on the geology of Ashley County, was 
informed that in the wells " a blue or light-gray clay occurs to a depth 
of 40 feet. This clay contains some leaf impressions." The character 
of plant-bearing clays found in other counties in Arkansas suggests 
that the clays may be available for making pottery and for other 
purposes. 
The only clay-working industry in Ashley County is a common 
brick plant run by Nolly Brothers at Hamburg. 
BRADLEY COUNTY. 
The northern and western part of Bradley County is a rolling 
country which slopes gradually toward the bottom lands of Ouachita 
River. On the east the lands drop away rather abruptly toward 
Saline River. Along the larger streams — the Ouachita, the Moro, 
and the Saline — the soils are mostly alluvial, and the original Tertiary 
sedimentary beds are exposed at only a few places. G. D. Harris 
states that "the undisturbed Tertiary deposits of Bradley County 
consist of light -colored lignitic clays, usually intermixed with more or 
less light-colored siliceous sand. Bluish or black clay is occasionally 
met with in digging or boring wells, and there is some pure lignite." a
