three diamond drills rigs in operation,
exploring this wonderful area to de-
termine the extent and direction of ITS
future ore reserves, and to plan its tn
ture mining and engineering methods.
The company has one manufactur-
ing plant IN Wyoming, the rolling
mills at Laramie where it employees
some 300 men. and the production OF
castings for railroad repairs and con
StruCtion. These works will undouDt-
eddy be enlarged and become one of
the important industries OF the Gem
City. s.
The character of the Hartville pres
is remarkable for high grade and puri-
ty, running from go to 20 per cent me-
tallic iron. with 2L to 3 per cent sill
ca, and only traces OF sulphur and
phosphorus. The ore is a red hema-
tite, occurring in slate. Hartville ores
obtained the grand prize at the Chica-
go exposition of 1893, in competition
with iron ores from all parts of the
world.
OF the many analyses published l
append one which may be considered
as a fair average sample.

The Seminoe Iron Deposit.
The Seminoe iron deposits which
eliminate at Bradley's peak, some 30
miles north of Rawlins, though less de
veloped are quite as remarkable as
those of Hartville. The center of this
great outburst OF iron constituting the

ciates, in 1886 and was afterwards pat,
ented by the company. Their proper.
ty consists of over 500 acres located
in a body at the base of Bradley's
peak. The outcrop is in a series of
peaks or knobs, which show boulders
OF iron, from ten to thousands of
pounds in weight. each. The ore is a
nematite occurring in states and
quantities., which in places are ira.
yersed by dykes of eruptive rocks. The
late Prof. Apgar of New Jersey made
an examination of this ground in 1891
and after a measurement of the ore
from lowest to highest o%utcrops esti
mated the deposit to contain CSC, 600.
600 tons.
Prof. Knight of the state school o
mines, after an examination in 1883
says, "On the south and west side OF
the peak iron extends for a distance
of a mile and a half. and. as near as
could ascertain, about n of a mile
in width" He says, further, Much
of this material is silicious ore, but
there are masses of pure hematite Of
unknown extent, existing in this de
post. Bradley's peak has been called
a mountain of ore, containing not less
than $500, 00O, 900 tons, capable o.
producing $50, OOO, 900 toni of pig IRON
He says he regards this estimate as
too high and that no n can make 8
true estimate without further prospect
ing and development. In a later re
port. speaking of the openings made
he says, "All of the work done thus fal
has been in large bodies of iron or iror
schist and in consequence a very large
tonnage has been exposed"
The value of this deposit is great.
enhanced by the opportunity of its
economic mining. The whole area o.
this deposit is practically an outcroI
of iron from the base of the mountain
up and along its lower slopes. The
ore can be mined or quarried from the
surface down to the valley, handled
with steam shovels and loaded upor
