Round Mountain. This hill rises about 200 feet above the surround- 
ing valley, and has in general outline, as seen on a map, the form of a 
dumb-bell. 
The sections given in fig. 19, taken at the opposite ends of the 
mountain, and the north-south profile section in fig. 20 show that 
while Round Mountain contains some coal and is capped by sand- 
stone it is made up for the most part of argillaceous shales.

Fig. 19.— Sections of beds at Round Mountain. 
The coal bed in section 2, fig. 19, was reported to have a thickness 
of 42 inches until 1892, when Mr. Charles Kantorowicz, of Little Rock, 
the owner of the Round Mountain property, engaged Capt. R. N. 
Scruggs to open the drift and definitely determine its thickness. The 
thickness here reported is that given by Captain Scruggs. 
Where the shales near the base of the mountain have been covered 
by the debris from its sides they are already deeply disintegrated. 
The great body of the hill, however, is of compact shale, weathering

cuboidal fragments. Much of this shale, possibly all of it, is avail- 
able for the manufacture of fire bricks, sewer pipes, furnace linings, 
etc., and for road-paving bricks. The following are analyses of two 
samples of shales from Round Mountain and of two other similar 
shales from Missouri and Ohio, the analyses of the latter being intro- 
duced here for comparison.
