THE IRON INTEREST.
HartViIIe Deposits Have Attracted
New York Capitalists.
The Investment Association Very
Likely to Take Hold.
Flattering Expert Opinions on the
Fields in the North.

1t is learned from V. Baker. resident
agent Of the New York Investment COM
pany, that this concern, which is one of
the strongest combinations of capitalists
in the country, is taking a deep interest
in the iron deposits tributary to CheY-
enhe. There is every prospect that the
association or some OF its clients will soon
take steps looking to the opening of the
field. Effective work to this end is now
being done. Several members Of this
powerful syndicate own Cheyenne prop
erty and have representatives here often.
The treasurer, Mr.. Lee, was lately
here and made a business like talk to the
Board of Trade.
To make a big splurge on this subject
just now would be rather harmful han
beneficial, but it may be asserted with
confidence that the outlook is very fatter-
ing. The iron is in the mountains, &C
cessible and in quantity and Cheyenne has
the call.
In his forthcoming report Geologist
Ricketts,, an eminent authority who is al
ways precise, candid and conservative,
thus concludes an exhaustive writeup of
the Hartville iron district:
The Sunrise mine could prepare for
an output of several hundred tons per
day in a few moaths, and continue ship
ments certainly for several years to come.
The Chicago claim could prepare for
shipments equally as soon as the Sur
rise. but as 30 little is known of her ore
body it is not legitimate to make even a
rough estimate of what the capacity of
the mine would be. Ii can only be said
that as far as developments go it prom. SEES
to contain an immense body of ore OF
indispensable quality. Should shipment
be made from either or both of these two
claims the stimulus given to iron mining
would cause active prospecting along all
OF the known ore lenses and in the states
for the search of others as yet undisc0v-
cred The belt between the Sunrise and
Chicago would also be prospected By drill
ing through the cap rocks from the
plateau.
THE low percentage of the Hartville
ores in sulphur and phosphorus is remark
able. The analyses lgiven are of average
samples, each representing a large guam
tity of ore; lone OF them contain sulphur,
three of them Contain only atrace OF phos-
phorus. The average of the five samples
IN the latter element is but Q. OF per cent.
Such ole is not only adapted to the manu-
facture OF Bessemer and open hearth
steel, but may be mixed with other ores
that contain too much phosphorus so that
the resulting mixture may be fit for the
same process Of treatment. The ores do
not contain appreciable quantities of man
ganese. The clay iron ores neal Rock
Creek and elsewhere along the Wyoming
division Of the Union Pacific railway con
tain manganese, and some of them are
probably suitable for the production OF a
manganese pig iron that could be used IN
conjunction with the Hartville pig iron in
the manufacture OF Bessemer steel.
In a letter TO VIM. Sturgis, Jr,. of this
city, G. Nj. Davidson, the celebrated Chi
cago chemist. says:
I'm order to give you a comparative
idea of the value of these ores, | add the
results of analyses of several well known
Lake Superior ores, which are accounted
The best to be found along our line.
These analyses / made several years ago
in the labratory of the Cambria Iron com
pauy. the samples in each case represent
ing shipments of the ore as received at
the furnaces. The samples you sent me
| have called the Sunrise ore. l con-
slider it one of the best Bessemer ores to
be found in this country. 1t is not only
high in iron. but very low in phosphorus,
and in my opinion would make an excel
lent grade of pig iron suitable for making
a high grade of Bessemer or open hearth
steel."
