the shaft. During FIVE years, when
mining was conducted by spells, it is
estimated that $50 tons of ore were
removed. A steam drill now at
work is down 26O feet feet with con-
tInuous ore to the bottom. Further
north, in same county, lead and zinc
was obtained from the 2nd Mages-
ian limestone and the everything
clays, the estimated value, by Geo.
logical Report, was $275, 900, To-
day very little mining is being done.

county is In the same formation. 1t
is very evident that the mineral
character of this rock decidedly inn
proves as it approaches toward the
state line, and that in Arkansas it
bscomes- the e,spaSsd- sssat -raiaszal.-
| bearing formation. 1t affords an
example that narrow view based
upon knowledge confined to a state,
or one portion of it, will not serve
as an unvarying guide when appli-
ed more generally. In Arkansas, it
should serve as the strongest kind of
an indication that the deeper and
underlying lirnestones should be
still richer in these minerals.
Instead of classifying the whole
range from the ST. Thomas (Swal-
lows 2nd) Sandstone to the St.
Peter, or Saccharoidal sandstone as
the 2nd Magnetism limestone, Prof.
Gallaher has wisely recognized an
intervening stratum of sandstone
which he has named the Nor
eau" As all of the sandstones
of the Lower Silurian age have
very similar resemblance, without the
kuo wledge of the Moreau it would
frequently be almost impossible for
the miner and geologist not to be
confused. 1t apparently is as per
sisteut as the Saccharoidal, and very
probably exists, where not eroded,
throughout the entire Ozark region.
AAN III OZdTh V,
both the Moreau and Saccharoidal
sandstones are exposed in the hill
side, the thickness of each, according
to Gallaher, not exceeding six feet.
He also states that they are exposed
IN many places on White river, but
neither one over1OIfeet thick. At Com
cts store, near Cedar Greek p. O.,
fancy county, Mo, there is sand
stone exposed that very probably is
the Moreau. 1t is but a few feet
thick, coarse grained, and highly
tinted with iron and was blasted III
to, no doubt, on that account. 1t
again is seen, and also the Saccha-
roidal sandstone, at the Mcintosh
mine or tunnel, on Rush creek In
fast whereyeP the Sasshan9id sa is l l0
Moreau is very apt to be seen to-
ward the base. In Stoddard coun-
ty, Mo-, it attains a thickness fmore
than soft, but in Marion and Boone
counties its average perhaps is 8
feet. Being situated about midway
between the st. Thomas and St. Pc
ter, or Saccharoidal sandstones, and
SO important a landmark, it is rath-
er remarkable that it should have SO
long escaped mention from other
geologists.
The Third Calciferous is the top
member of what Swallow and other
geologists termed the 2nd Magnes-
ian Limestone, and, of course, rests
upon the Moreau sandstone. OF
this formation, Prof. Gallaher has
to say, ut consists of four or FIVE
thin beds of true limestone and as
many thick beds of buff colored cot
ton rock. 1t is approximately oneI
third trae limestone and two-thirds
cotton rock. 1t also makes consid-
cradle ebert, but not so much as
either the First or Second Ca,-iGr--
Gus. The gsuriice of the
White river basin, in Missouri and
Arkansas is largely made up of this
rock. 1t, like the Secord Calcifer-
Gus, is also ore bearing but its ore
bodies are dispersed in clay blankets,
old canyons and sinks, and are not
generally profitable. They are
as prolific of mineral propects as any
other rocks and have yielded consid-
cradle lead and zinc, but no extenl
sive and profitable deposit OF ore
has been located or developed in any
member of the Magnetism Lens
| above the First Calciferous."
Right here we stagger up against
a proposition which is not so easily
demonstrated unless, indeed, it is n
tended to apply in a limited W.
