In the NE. \ sec. 35, T. 6 S., R. 18 W., about a quarter of a mile 
bove Sulphur Springs, Mr. Siebenthal reports 4 feet of dark-gray 
clay exposed in the bank and bed of the creek. The weathered 
upper part of this bed is dark and is said to res.emble the clay in the 
Perla switch beds above Malvern. It is said that some of this clay 
has been successfully used for manufacturing pottery. A practical 
test of it was made by the Rev. Mr. Clark, who burned it on the 
west side of the Ouachita, below Rockport.
