DALLAS COUNTY. 77 
The same bed crops out half a mile farther east, and search would 
undoubtedly reveal it in all the hollows in the neighborhood. 
Claries Creek clay.— In the SE. \ sec. 1, T. 8 S., R. 15 W., at an 
elevation of 280 feet, in the bank of a small drain running into Clarks 
Creek, there is an exposure of 4 or 5 feet of tough, plastic clay con- 
taining scarcely any grit. With the exception of about 1 foot in the 
middle of the bed, this clay is light gray in color. The middle layer 
is of lavender color and has a peculiar odor and a sharp, bitter taste. 
This very interesting clay deserves a mote extended examination 
than it has been possible to give it in this investigation. In several 
places within a mile or so of this occurrence, clay of apparently the 
same quality outcrops at the same elevation, so that there must be 
almost unlimited quantities of this clay. 
Ramsey clay. — The Ramsey clay is exposed about one-half mile 
east of Ramsey post-office, in the NW. \ sec. 9, T. 10 S., R. 13 W. 
The clay crops out in a drain beside the Fordyce-Princeton road at 
an elevation of about 265 feet. The bed is exposed to a thickness of 
10 feet. The clay is light bluish gray in color and very plastic, and 
the small amount of -grit is very fine grained. 
The proportion of alumina and silica in this clay is such that its 
refractoriness would be high were it not for the injurious amount of 
fluxes it contains, especially of magnesia, of which it contains more 
than any of the other clays analyzed. As it is, its refractoriness 
compares favorably with that of the Welch clay, and it may be used 
for all purposes for which the Welch clay is suitable. The quantity 
of this clay is apparently unlimited. 
Wormac's clay. — W. L. Wormac's clay bed is in the NW. 'J NW. \ 
sec. 29, T. 10 S., R. 14 W., at an elevation of 260 feet above sea level. 
It outcrops to a thickness of 4 feet at the foot of the west bank of 
Freeo Creek. A small drain empties into the creek at this place, and 
the clay crops out in this drain up to a spring which is 10 feet above 
and which probably emerges just above the clay. The clay also 
forms the bed of the creek for some distance south (downstream). 
This clay is of a dark slaty blue color, with a waxy luster when freshly 
exposed, but dries to a dull light drab. 
The upper part of the bed, as exposed in the drain, is lighter in 
color. The clay in the creek bank breaks off in large, roughly rec- 
tangular blocks, from which small cubical pieces weather off, leaving 
a peculiar, angularly indented surface. The clay is plastic and the 
grit is very fine, being almost imperceptible. 
In appearance this clay differs widely from the other clays of 
Dallas County, and on analysis shows a like difference in chemical 
composition. The degree of refractoriness is too low to permit its 
being used as a potter's clay, unless it be as an ingredient in other 
clays, and it is difficult to see how it could be beneficial as such.
