going steadily on for the erection of q
large tin reducing plant at Bear Gulch.
Dr. Scott is at the head of the scheme,
and rs has before been stated has pur-
chased a large number OF claims in that
vicinity. Recently the plan of building
a plant to treat 400 tons of ore daily was
laid before the officials of the c., B. &
O.. and at the next meeting of the board
Of directors an extension of the road TO
Bear Gulch will probably be ordered

McARTHUR-FoRREsr PROCESS.
| The McArthurForrest Gold Extratine
Company has "foretsalled Fall danger of
litigation and trouble by buying the
Simpson Process, which was an older
patent and very similar to their own,
with the exception that they precipi-
tated on zinc plates instead of zinc shay
ings. Those who thought to escape
paying the royalty on account " this
conflict, will now have TO 'look pleasant
and ante-up." The Denver Mining
Exchange Journal Of the 81 st inst, con-
tains long article defending the Me-
Arthur-Forrest Process Of ore reduction n
against the attack made upon it by the
Engineering and Mining Journal of
New York city. The defense is an
able one, and if the New York sheet
will be fair enough TO read it, il
will forever let up on its attacks on a
process that is revolutionizIng ore
reduction in the United States.--Salt
Lake Journal
The McArthur-Forrest Process con-
tinues to be we'll regarded and favor
ably mentioned in our foreign ex-
changes, as for example, the Australian
Mining Standard, of Sidney, in it's issue
of April 23rd, states: Those who have
been instrumental in floating the Au.
stralian Gold Recovery Company are
confident that the systematic working of
the McArthur-Forrest cyanide process
in these Colonies will prove of as great
assistance to the gold industry in Au-
stralia as it has proved on the South
African fields. As recently mentioned,
the process is instrumental in swelling
the gold returns Of the Rand to the ex-
tent of over 10000 ozs. per month, and
il is expected that by next June the
yield from tailings treated by the pro
cess will reach 10000 ozs. per MONTH"
In later number of the same exchange
its correspondent from Johannesburg
Grove" reports that the great gold
property in that quarter, the Robinson,
is subjecting its large deposit of tailings
to the process with results that appear
to be very good" and adds
"By this process very large quantities
are treated, and although the percentage
Of extraction does not generally exceed
go per cent, the quantity treated makes
the process a sound commercial success,
whilst the resi9ues are hardly likely TO
he made TO pay by any other known
process. Cyanide is the solvent, and
ere long the company will demonstrate
the working of the process in Australia,
as read that they intend commencing
operations out there"
Reports of similar satisfactory results
here in the United States reach us from
Montana relative TO this process, through
the Anaconda Standard Of June 10th, as
follows:
"The cyanide process of treating re
bellious gold ores has proved success
at Quartzbury, Messrs. Geer & Benham
having saved 9S per cent of the gold in
the sulphurets from the Gold Hill mill
at an expense of less than So per ton.
The same company will soon erect
works of 50-ton capacity at some other
point in the Basin. Now, that il is as
certained that sulphuret and other re-
bellious gold ore can be reduced at very
small cost, prospectors are locating
claims on veins carrying such ores, and
considerable development work will be
done on them during the summer. The
cyanide process is indeed. great thing
for this country"
We also hear Of the early erection of
three or four plants in Arizona-or one
in Maricopa and two in Yavapai coun-
ties-for the the treatment of gold ores
in that quarter by the same method
which, assuredly, promises to be
greatly desiderated addition to our me-
tallurgical resources. or to such an ex
tent that we hardly comprehend the in
centive to the sksptical spirit-or rather
one Of downright detraction-which
this already widely-used process seems
to have encountered, in certain quarters,
here in the United States a spirit that
is seemingly alloyed to serious extent
with matter foreign altogether to the
interests of metallurgical progress
