Tin Men Interviewed.

Gently left the Black Hills for New
York were interviewed at Chicago by a
Tribune reporter, from which we ex-
tract the following:
Il can say," said one of the men in
terested in the enterprise, that SO far
as surface indications demonstrate, the
greatest deposit Of tin quartz yet found
| in the world is now visible in the Black
Hills district"
Are the combinations there such as
| TO make it more difficult to extract the
product than at Cornwall %
"Most decidedly no. The Cornwall
mines, as you may know, were first
largely copper mines. The product still
has mixed with it some copper, as well
as half a dozen other base metals. The
separation of the tim from these com.
binntions is expensive. The Harney
Peak deposit is absolutely free from
troublesome combinations with base
metals"
| Much has been said about the in
vestigations which have been carried
on for the purpose of finding ont some
method by which the Black Hills ore
could be cheapy and easily treated.
An i'm preston exists that II great OBJ
stacle, perhaps an insurmountable one,
exists i'll the chemical difficulty of ex-
tracing the concentrates, Is this all a
mistake?"
A MISTAKE CORRECTED.
at most certainly is. There has been
much rubbish talked and printed about
this matter by people who know nothing
of the tin business. As "A matter Of fact
everything is in favor Of the American
mines as compared with the Cornwall
mines for the cheap manufacture Of tin,
with the single exception Of wages. 1t
was stated that we were looking for a
successful process of treating this ore.
The facts are that we have not been
looking for any new processes, but
studying how much Of the old machn-
cry which now has to be used in the
Cornwall mines we will be able to dis
| card entirely. The treatment necessary
to extract Harney Peak tin from its
matrix is more simple than from any
| tin ore.
Besides the entire freedom from re-
fractory combinations with base metals,
| which adds much to the expense of the
production of the Cornwall product
there is another feature of the American
ore which is an enormous point in Its
favor. The crystals Of tin IN the Corn,
wall mines are SO small that the whole
mass has to be reduced to impalpable
powder This is SO hne that an average
of Il per cent of the total is lost in the
concentration and carried away in what
is known as the shines" The crystals
of tin in the Black Hills quartz are az
course as ordinary oatmeal. Practically
the whole of the ii per cent of waste in
the English mines will be saved here
without expense. Then there are other
features which will act greatly in favor
theAmerican mines. AT Cornwall they
are now down 1900 feet. The expense
of working at this great depth and
keeping the mines free from water is
enormous. All the timber for supplying
the mines has to be brought from Nor
way, Sweden and Quebec.
A GREAT SAVING.
In the Black Hills the ore. crops out
above the surface. Tunnels and drifts
can be run on many veins without any
interference from water. The ground
is covered with heavy growth of fine
timber, and there is pure water in
abundance for every purpose.
The company which has been formed
to continue the development which the
New York syndicate began is backed by
large capital. lit is known as the Har
ney Peak Tin Mining, Milling and Man
ufacturing company. The capital stock
is e3,00o,000 sterling. This stock has al
been subscribed and remains in the
hands of a few holders, and there il
little probability of any of it coming or
the open market in this country OF ir
England.
Among some Of the English capitalist,
who are interested are Lord Thurlow
Earl Morley, William Garlett, Edwar,
5. Barring Gould, and Il. NJ. Denny
Among the New York men who are in
terested are d. S. Appleton, the pub
Usher, George Ehrett, Henry Cawson
Jr., Louis May, James Wilson. William
Ransom, Samuel Untermeyer, an,
; James Flanagan.
Practical mining has now commenced
The mining operations are carried o,
under the direction of Cornish captains
sent over by the London Advisor,
board, which has the absolute practica
management of the property so far a
development is concerned.
TIN PLATE MANUFACTURE.
"As soon as practical results are had,
said one Of the parties interested in tn
new venture, "as soon as it is demon
strated by actual production that thi
country can turn out merchantable til
in sufficient quantities, it will be tn
