syndicates amply able to forward
of such financial magni-
tude- However, the thing most
gratifying to those having the wei
fare and progress of Idaho at heart
is the absolute demonstrators of per-
manence in ore bodies and values.
The Mining Journal was afforded
every opportunity for examination on
the Blue Jacket, Old and South Pea
cocks, River Queen, and Iron Dyke.
these being the most extensively
developed properties, and we may
state at this time thatin no one of
them has surface indications for
depth proven delusive. There are
assures and contacts, with a segre-
cation most astonishing The Blue
Jacket is a clean-cut contact between
lime and granite, while the assure of
the Peacock is perfectly stable, main
tanning its entire characteristics to
below the 300 fit level with remark
able uniformity. Mr.. Hancock's
company has been operating a dia-
mond drill for some time on the De-
corah, Arkansaw, and other claims
in their large group. Up to the
present time they have drilled about
1890 it. IN various directions, the
greatest depth in one place being
900 fit. The work of the drill has
been far from unsatisfactory. prov
ing that here, too, the surfure show
ings have great depth. From the
fact now known land known only
through the thorough and competent
development carried on the Peacock,
DEBORAH, River Queen, and Iron
Dyke it will henceforth be impossible
for successful detraction from the
merits Of the Seven Devils deposits.
1t has been maintained that the test
of copper property is depth; that
it's permanence cannot be depended
upon till after water level is reached.
At the Blue Jacket mine today, as
for long time past, B carloads per
week of 40 per cent copper ore is
being shipped, and it comes from
below water level; the shaft
is being sunk with all rapidity, and
the power water station is but few
feet above water level, 1t is not at
all out of place to call at least the
Blue Jacket, South Peacock, Old
Peacock, River Queen, and the Iron
Dyke mines That this is so is due
to mineral and a thorough knowledge
of mining, for in no place has the
uniformed been more at sea, OF
made more complete fizzles, than in
the Seven Devils; persistence, and
care, for no section of country has
been more heavily handicapped than
this.
Beside the great variety of copper
ores, there are IN this district other
things of moment and interest to
mining men. The country rock is
granite, traversed by mighty dykes
of porphyry and of lime, the latter in
many cases being marble. The ledge
matter is quartz, or garnet
quartz, many perfect and large
garnets being frequently discovered.
Epidotes are frequent, especially
with the garnet, though we have one
embedded in solid carbonate Ere
quently the ore comes out clear and
handsome in pure white quartz, and
that it is usually of high grade bu
adds to its beauty. On the Old Pea
cock was discovered, the new mlnera
Powellite, first found by w. H
Melville. 1t is whitish-gray, sof
material, resembling graphite in it
feel and polish. Another materia
found is lamellar hematile, some
times occurring in ore, one speci

This road, built by Albert Klein
schmidt at cost of over $40, 000
is one of the great undertakings O
the camp, adding largely to tn
facilities for ore and machiner
transportation, and having larg
tendency to the upbuilding of tn
camp. The building Of this roa
