several or the nuor spar mines,
notably the Tabb, the Yandell and
the Holly, kidneys and large cubes
of galena occupy portion of the
vein, and are separated very easily
from the spar, The LaRue, the
Tabb and the Holly veins through
out their entire length carry both
lead and zinc. So far, no ores of
lead other than galena have been
noticed, although in such a lime
formation we may expect carbonate
of lead in quantities.
THE ORES OF ZINC.
-Four of the great veins men,
toned above are very prolific in
zinc. The Holly shaft at 60 feet
depth displays an astonishing
amount of orange colored zinc
blende: the same class of blende
is noticed in quantities in 26
foot vein in what is known as the
Bib shaft on the same vein. The
zinc blende in this enormous vein
is disseminated very thoroughly
throughout the entire width, The
analysis of this ore is

An extensive bed of carbonate of
zinc has been established on pro-
perry owned by Messrs Blue d
Num-, the oresbeing singularly
free from any deleterious matter,
and assaying as follows;
| Carbon dioXide ............3J.2
! Zinc oxide .................G4.
Four-fifths of this zinc oxide is
pure zinc, and it often contains
some cadmium. Another form of
zinc which seems to be in profu-
sion in several of our veins, is sill
icate of zinc. Very fine examples
of massive character are found
on Aroperty owned by Mr.. c. M.
Miller, of Canton, Ohio. Indeed
zinc is very evenly distributed
throughout this entire mineral
section. 1t being in we'll defined
fssure veins, with perfect walls,
I its mining will be very much cas-
Ter and cheaper than in most zinc
districts. An analysis of zinc sill
icate shows:

There are several other ores of
zinc which will no doubt be found
in this district, from time to time.
as more developments are made.
Only two ores of the metal cadmi
um are known, but it exists with
zinc in zinc blende in the Bib
shaft and at times in both car
Donate of zinc and zinc silicate,
Cadmium is white like tin and is
so soft that it leaves trace upon

There are extensive veins of ba-
rytes located in at least two sec
tions of the district; the one which
the Illinois Central railroad cuts
through Just south of the Mexico
station, being perhaps superior in
color and composition to the 9th
ers. The comparative cheapness
with which this product can be
mined and shipped will ere long
bring it into competition with less
favored localities, as it is almost
snow white, of very heavy specific
gravity, and has the lustre or crys-
tallization of freshly corroded
white lead, Kaolin, potter's clay,
pipe clay, red and yellow ochre,
lumber, and fire clay abound in ma
ny sections of the district.
GENERAL SUMMARY.
The foregoing is brief review
of mineral section of the coun-
try but little known to the outside
world. Situated on great trunk
railway, and midway between two
navigable rivers, it offers to the
man of moderate capital opportu-
mites seldom afforded There is
a great and growing demand for
every mineral OF earth here men,
toned at very profitable prices
