GRANT COUNTY. 105 
some places, especially where heavy beds of sand are superimposed 
upon them, it is some shade of red. 
In the NW. \ SE. \ sec. 35, T. 4 S., R. 15 W., near the mouth of a 
small tributary of Saline River, there is a bed of light-drab and 
fine-grained fire clay, underlying a 2-foot bed of lignite. The clay 
is exposed for about 2 J feet, but its total thickness is not known. 
The locality is difficult of access and at present without transportation 
facilities. 
The lignite found at this locality has been tried in blacksmiths' 
forges at Sheridan with indifferent success. Several sacks of it 
were taken to that village and burned in grates; it is reported to 
have burned well. On exposure it falls to pieces, eventually becom- 
ing a coarse powder, which circumstance would prevent its general 
use for fuel were it otherwise suitable. 
A tough, plastic, gray clay outcrops on E. G. Davis's place, in the 
SW. \ NW. \ sec. 25, T. 6 S., R. 15 W. A well 300 yards west and 
about 25 feet higher went through 25 feet of sand. The well at the 
gin in Sandy Springs, which is about 400 yards south of the first well, 
showed from 8 to 10 fejst of white sand. The road for 1^ miles 
southwest of Sandy Springs shows red sand but no gravel. At one 
place the sand much resembles chocolate clay. 
About 20 feet of a dark sandy clay outcrops in a stream bank in 
the SW. \ NW. i sec. 31, T. 6 S., R. 14 W. 
Stephen Heard's well, near the northwest corner of the SW. \ 
sec. 31, T. 6 S., R. 15 W., shows the following section:

Plastic clay is reported near the southwest corner of sec. 18, T. 6 S., 
R. 15 W.; also on the Davis farm, near the center of sec. 10, in 
same township. A very white plastic clay is reported to occur in 
same township near the schoolhouse in sec. 9, about the middle of 
the west side, on a small drain flowing into Brushy Creek. 
Plastic gray clay outcrops in the NW. | NW. J sec. 31, same town- 
ship, in a drain flowing south in Gum Bottom. Similar clay which 
has been used for pottery outcrops in drains and is exposed on the 
breaks of the hills farther east all along the north side of Gum Bottom.
