116 THE CLAYS OF AKKANSAS. 
In addition to the localities mentioned above, it is highly prob- 
able that fine pottery clays are widely distributed throughout all of 
that part of Hot Spring County lying south and east of the St. Louis, 
Iron Mountain and Southern K airway. 
MAGNET COVE KAOLIN. a 
The rocks of the Magnet Cove are largely feldspathic, and in 
places they are decomposed to great depths. The only kaolin found 
in Magnet Cove, however, occurs in a few small scattered bands and 
patches, while the residuary clays as a whole are full of grit, iron 
oxide, and incompletely decayed fragments of mica. These clays 
are not available for brickmaking, and even the earth used for lining 
chimneys is hauled from the region of sedimentary rocks outside of 
the cove. 
A well 49 feet deep, dug at the residence of J. F. Moore, in the 
SW. J NE. \ sec. 19, T. 3 S., R. 17 W., is all in eruptive rock, decayed 
in place, much of which is soft enough to be removed with the spade. 
Only very thin streaks of kaolin were found in this decayed rock. 
A small deposit of kaolin is uncovered east of I. N. Johnson's 
house, in the southeast corner of the cove, NW. \ NE. \ sec. 29, 
T. 3 S., R. 17 W., and a few layers are exposed in the Hot Springs 
road at the west end of the cove near Thomas Holt's house, and also 
in his well, NE. J NE. \ sec. 24, T. 3 S., R. 18 W. 
At John Neusch's house, NW. \ NE. \ sec. 30, T. 3 S., R. 17 W., 
small streaks of kaolin, perhaps 2 inches wide, were found in digging 
a well. The earth taken from Mr. Neusch's well was examined 
shortly after the well was dug. The little lumps of kaolin in it are 
of excellent quality, but there is nothing to lead one to expect to 
find it in workable quantities. Afterward lumps of this kind of 
kaolin were sent to the office of the State survey for examination, 
with the report that there was an inexhaustible quantity of it, but 
following up this rumor it was found that the sample came from 
Mr. Neusch's well. None of these small deposits have any economic 
value. It is possible, however, that kaolin may yet be found in 
Magnet Cove in quantities and of a character that will render it 
valuable. This possibility is suggested by the nature of the rocks 
and by their profound decomposition. 
Bringier speaks of china clay in the " Wichita" cove, 6 and Doctor 
Owen mentions beds of kaolin from 3 to 15 feet in thickness. 6 " These 
reports have not been confirmed. The places referred to by Owen 
were "in wells dug by George Piles and Mr. Plank;" if the locations 
can be found it may be well worth while to verify the matter.
