The mineral wealth of Montana display
ed at the Exposition, says the Times Demo
crat, is something wonderful Products
from the Anaconda mine copper is nota-
BILE Specimens taken out at a depth of
800 feet, will yield fully 20 per cent of
copper. of the highest grade. Beside this
valuable sample others are shown, varying
i'm grade to the lowest, of II per cent.
These mines are operated by company
having the largest reduction works in the
world.
A MILLION AND HALF
having been expended last year in inn
provements alone. Turning to an adjoining
stand series of boxes containing ore from
Clark's Collusa mine were next seen, illus
trating the consecutive processes OF the
reduction of copper from the crude ore, as
taken from the mine, to the ingot copper.
The process in brief shows the ore as 1t
first appears crushed. then as sized in re-
volving screens then concentrated by
water by jigs. producing concentrates car
rying about 30 per cent. of copper. Next
il appears as calcined to eliminate the
sulphur and other bases, then rs smelted in
a reverberatory furnace into a "regulus,"
containing % per cent. of copper After
further smelling operations the ore again
appears as a white metal, carrying about
~ per cent of copper; next as blister"
copper. and lastly. after further refinement
by smelling. into ingots OF nearly pure cop
per, ready for the market.
After viewing the copper ore specimens
from all of the different mines, attention
was next turned to gold and silver ores,
monster piece of which, from the Drum
Lummon mine. weighs 1,1o0 pounds. This
mine was sold 10 English capitalists for
S3,OO0,000.
From the Moulton mine a specimen,
taken out at 500-foot level, weighs l,00o
pounds. Ii ~

mine The products of this mine amounted
to sJO0,000 last year
From the Bel. mine is another magniii-
cent specimen carrying 60 per cent OF
copper, thoroughly impregnated with great
MASSES of silver.
The Lexington mine affords further ex-
amples of richness In silver ores. In addi-
tion To these are shown upon two great
pyramids, ores from the A. Nj. Hotter mine,
the Granite Mountain, the Comet, the
Hecla Consolidated, Maria, Neptune, Liqui-

Reduction Company, the latter company

rous to mention have their respective ex-
hihiis Above the pyramids a sign
rears high aloif, bearing the eloqent IN
scription; These minerals from Montana
all represent paying mines"
In cabinet all to itself, wondrous
sight is exhibited of gold ores, all from
the Atlantic Cable mine, located IN Deer
Lodge county. The cabinet represents the
equivalent of $4,000 in specimens, one
piece alone containing $500 OF gold 900
l000ths fine. The product of this mine
last year was S250,0O0. In further evil
dence of the mineral production of Mon
tana during the past year, history records
S23 SOC, 900. which is greater than that of
any other State or Territory in the Union.

taken from veins from twelve different dis
tricts, representing veins from five TO twen-
ty feet in thickness. This coal is Ignite,
found in the tertiary formation, but of
good coking qualities.
Rich samples of iron ore are also seen,
thus completing the category of all the
potent minerals in Montanas rich collec-

are the various specimens of bunch and
buffalo grasses which form conspicuous
part of Montana's special agricultural de-
partment. These grasses are OF the most
nutritious kinds and afford nournishment
foe the million and a half head of stock
which now roam upon the valleys and
plains of Montana OF this stock 100000
head of sheep are included, which find no
other sustenance save from these grasses.
1t must be understood in this connection
that the rigors of this Northern cline are
modified by warm

The chinook winds are life-giving alike
to man and beast.
While other States are exhibiting greater
varieties of potatoes, none equal Montana
in the size and nutritious properties OF her
ground fruit
In the way of cereals, the exhibit shows
wheat, oats, barley. peas, and other va
rieties in perfection of formation. Every
grain is fully matured. According to the
census statistics Montana leads the van in
the number of bushels of wheat per acre,
showing the rare productiveness of her
soil. Wool, notably free from burs and
excess of grease, is also shown, representing
