some OF the hardest rocks were made
at the time of elevation of, at least
this portion of the Rocky Mountains
| and that the waters of the inland
sea thus displaced rolled in torrents
and billow in the direction now
pursued by the San Juan, and Big
Colorado rivers, and found an out
let into the Gulf of California.
Similar results, on a much smaller
scale, followed the uplift of the
sedimentary deposits of the Ozarks in
southern Missouri and Northern Ark
ansas Since then, in addition to the
assembled beds of "hoat" mineral
and what had found lodgment in
the various rents and openings near
the surface, a process of Resembling
and reconstruction has been, and
still is. going on as previously
claimed and stated. There ap-
pears to be nothing remarkable nor
singular about this, but to suppose
that the real and original genesis OF
these minerals is due solely and
purely to water solutions is difficult,
for one at least, to comprehend and,
| naturally calls for an answer to
to the question, from whence did the
water acquire these mineral salts
or solutions?
Although the 3rd Magnetism lime
stone (Gallaher's 1st Calciferous) is
limited as an exposed rock in Ark
ansas it cannot be too deep at
many places for practical mining
operations and, owing to it's shield

should be sulphides of superior
quality The general and extensive
order of naturalization of the over
lying formations which do constitute
the couptry rock should serve as a
| most valuable assurance that be-
meath, in the 3rd Magnetism. or
FIRST Calciferous, there are the
richest stores of mineral There is a
considerable area of this member in
Ozark county Mo-, along the North
Fork of White river and Bryant's
fork, where it is exposed near the
bottom of drainage.

ian division. The few fossils found
in this rock are principally the
Straparollus, Murchisonia, and Or

About the most instructive report
on Ozark county is that of DR..
Shumard, which has a special in.
terest and value in this respect
since it brings us to rde northern
boundry of the Northern Arkansa
mineral territory. For the other
Missouri counties bordering on the
State line, it must be said they, as
vet, have received scarcely mention
in Geological Reports.
Shumard states that in Ozark
county, all the formations from the
base of the Chemung down to the
Saccharoidal sandstone are entirely
deficient. But the sandstones and
Magnesia Limestones of the calcif-
erous sand-rock are developed on a
large scale. In fact nearly all the
rocks of the country belong to this
geological period. The strata vary
considerably in character in different
parts of the county, and often tn,
change is quite sudden. Thus we
sometimes find a heavy bed o
Magnesium Limestone passing into
| a perfect quartzase sandstone in 6
distance of a few hundred yards
The strata also differ considerable,
