DALLAS COUNTY. 79 
The analysis shows a kaolin of a fair degree of refractoriness, the 
water content coming more nearly up to the accepted formula for 
kaolinite than that in the Little Cypress Creek kaolin. This kaolin 
will probably be available for the same purposes as the Little Cypress 
Creek kaolin. 
OTHER CLAY BEDS. 
The following notes on clay beds, which cover not only outcrops 
observed, but localities where clay was reported to occur, is inserted 
here on account of their possible value to prospectors. 
In many cases the clay has been described as " sandy." Where 
this term has been used the sand is usually present in quantity suffi- 
cient to overcome the plasticity of the clay, or rather to lower the 
plasticity below the point at which it is available for ceramic pur- 
poses. One remedy for this fault consists in mixing with the sandy 
clay another clay of higher plasticity. Another remedy consists in 
washing out the excess of sand, a process that entails so much addi- 
tional expense that it is impracticable except where the washed 
product is of a superior quality. 
The exposures will be taken up in the order of the townships, 
beginning at the northeast corner of the county. The elevations 
are given in feet above mean tide level of the Gulf of Mexico. The 
elevation given for a well is that of the mouth; the elevation given 
for a natural section is that of the base. 
Township 7 S., range 14 W. — Two feet of white plastic clay out- 
crops in a gully about 600 yards west of Ivy post-office, and is over- 
lain by 6 or 8 feet of gravel. This is at the same elevation as the 
Crowder clay, which is less than half a mile distant (see p. 76), and 
is probably continuous with it. Elevation, 290 feet. 
"White plastic clay is reported on Gum Creek, in the SW. J sec. 29. 
Township 7 S., range 15 W. — In the SW. \ NW. \ sec. 2, in a gully 
just west of the Tulip-Sandy Springs road, there is an exposure of 15 
feet of clay resting on white sand. The lower 7 or 8 feet is white 
plastic clay of apparently fair quality. It is possible that the white 
sand is a sandy kaolin similar to the Little Cypress Creek kaolin. 
Elevation, 360 feet. (See also p. 78.)
