PULASKI COUNTY. 173 
outcrops are concealed by the soil and surface materials that have 
fallen down over them. 
The elevation of the outcrop varies somewhat, but it lies for the 
most part between 260 feet and 302 feet above sea level. 
In and near the city of Little Rock there are only a few places at 
which the clays can now be worked advantageously. This condition 
is due to the value of the land for building purposes, and not to any 
defect of the clays themselves. In spite of this it is possible that 
there may be places in the southwestern part of the city where the 
clays could be worked, while the nearness to market and to trans- 
portation would be in favor of such an enterprise. 
On the south side of the river there is a brownish-yellow brick 
earth similar to that which forms the surface in sec. 28, T. 2 N., 
R. 12 W., overlying the other clays in different places west and south 
of Little Rock. 
Between the high shaly hills on which the asylum for the insane and 
the reservoir of the city waterworks have been erected and the river 
there is a narrow strip of this same brownish-yellow clay. It lies in 
a long, narrow belt between the hills and the bottom land of the river. 
At Ward's old brickyard this brick loam rested directly upon a red 
sand. The section is as follows:

Between the point where the St. Louis, Iron Mountain and Southern 
Railway crosses Sixteenth street and the outcrop of the blue shales 
and quartz ledge at Nineteenth street a small deposit of this brownish- 
yellow brick earth appears to have been laid down in a sort of pocket 
among the shales, with its opening toward the south. The yellowish 
loam here has a depth of about 3 feet. 
Another small deposit of the same material is found on the corner 
of Rector avenue and Eighteenth street. Here the brownish-yellow 
loam has a thickness of 2 to 3 feet. It is underlain by a bluish pebbly 
clay, mixed with sand. A well bored through this clay shows it to 
have a thickness of 19 feet. It is underlain by sandy clay. The 
underlying sandy clay is seen in the bottom of a small stream that 
runs along the south side of the old Bragg brickyard. The clay 
covers only a small area, most of it lying between gravel ridges. 
On Arch street between Twenty-fourth and Twenty-sixth streets, 
at C. W. Clark's old brickyard, the brick clay was about 2 feet thick 
before it was exhausted, and was underlain by a stiff, bluish-red, 
streaked clay containing pebrjes, which is said to be underlain by 
gravel.
