Carboniferous shales. The section at this exposure is as follows:

Watertown gravel 2 
Pottery clay streaked with red 2 
Gravelly red clay 2 
Black shales at base. 
The upper gravel of this section is only 2 feet thick where the clay is 
exposed, but on the hillside south of this exposure it is probably from 
15 to 20 feet thick. 
BRICK CLAYS. 
Enormous quantities of good brick clays lie in the second bottoms 
of Arkansas River south of Altus, extending eastward along the 
river as far as the mouth of Horsehead Creek. At some places, as on 
the road from Altus to Roseville, these brick clays are from 20 to 30 
feet thick. The bricks made from these clays are gray in color and 
spotted with iron. 
The area of brick earths around Ozark is limited to a small portion 
of the NW. I see, 36, NE. | sec. 35, SW. \ sec. 25, and SW. \ sec. 26, 
T. 10N.,R.27W. 
No bricks have been made at Ozark for several years. The last 
were made by W. A. Jennings in 1886. 
About 1 mile north of the Roseville ferry, near the center of sec. 33, 
T. 9 N., R. 26 W., the Altus-Roseville road crosses a terrace of, red- 
dish, sandy, horizontally bedded clays similar to those of the terraces 
at Argenta and Fort Smith. A^ this locality the terrace is about 25 
feet high. It may be traced for about 300 yards east of the road to a 
point where it is cut off by a small stream, and for about 100 yards 
west of the road. The clay is the same as that used for the manu- 
facture of building bricks at Pendle & Morrison's yards in Fort Smith 
and at Argenta. 
This terrace can no doubt be traced, at about the same elevation, 
from 50 to 75 feet above the river, for long distances on both sides of 
the river bottoms, though in many places it has been entirely removed 
by erosion. 
At the church in the southwest corner of the SW. \ SE. \ sec. 28, 
T. 9 N., R. 26 W., a well about 30 feet deep shows a surface of yellow 
sandy clay or loam, while the materials brought up in cleaning show 
the bottom to be whitish gravels stained with iron. 
Near the south line of the section in the SW. \ SE. \ sec. 21, T. 9 
N., R. 26 W., a well 21 feet deep has the following section:
