He found gray clays exposed on the road running north from Johns- 
ville toward Warren and 4 or 5 miles from the former town. He gives 
the following record of the well of Lee Hammaker, in sec. 8, T. 12 S.,

At Alga Bluff, on Saline River, in sec. 21, T. 13 S., R. 9 W., a 
section about 75 feet thick is exposed. The lower half of this section 
contains two thin beds of lignite and two beds of clay — one 3 feet 
thick, between the beds of lignite, the other 16 feet thick, overlying 
the upper bed of lignite. These clays have not been examined 
chemically, but they are worthy of examination and practical tests. 
At Crawfords Bluff, on Saline River, beds of lignitic clay are 
exposed again. In the region between Johnsville and Long View, 
wherever the drainage has cut deep channels, these lignitic potter's 
clays are to be looked for beneath the heavy gravels. 
About one-half mile west of the point where the railway from 
Monticello to Warren crosses Saline River the railway cuts a terrace- 
like ridge. The upper 4 feet exposed in this cut is a bright-red soil, 
and the underlying bed is purple clay. 
About Warren the surface loam is in many places adapted to brick- 
making, but so far as could be learned no clays of importance beyond 
the brick earths have been found in the immediate neighborhood. 
The Tertiary (Eocene) fossiliferous beds are exposed in the railway 
cut in the town. Over all of Bradley County the Tertiary (Eocene) 
beds are either exposed at the surface or are concealed by their own 
weathered remains or by a thin sheet of Pleistocene gravel and sand. 
Most of the weathered Tertiary clays of this county form excellent 
brick clays. 
In sec. 20, T. 14 S., R. 9 W., a well dug beside the road leading 
from Warren to Johnsville has the following section:

It may reasonably be expected that valuable clays will be found in 
connection with the lignites known to exist at various places in
