to admit the escape of the quartz when it i
reduced to an impalpable powder. Into thi
hollow cylinder are placed more than thou
sand cast iron balls about one inch and hal
or two inches in diameter. This cylinder i,
made to revolve with great rapidity, and tn,
balls within the cylinder are thrown from sid,
to side with such force, as more eifectually t.
pulverize the quartz than any other process
yet discovered. The quartz thus pulverizet
is dissulphurized by passing ii through ho
fame Of fire, and then mixed with water ant
placed IN . large bell shaped kettle with IT,
base enverted. Into this kettle is placed ,
revolving machine with Ranges extending
from the centre to the circumference, with
quicksilver at the borom-so that when it il
/ in operation such currents of the solution are
formed as to throw every particle of it il
contact with the quicksilver at the bottom
which attracts the gold to itself, and from the
amalgum ready for the retort and its reduc
ton to bullion. This latter process is the one
il use by the Boston company, at the Nevada
Mills, under the direction Of the gentlemanly
and polite Superintendent, Mr.. Adams.
The next process in order is the smelling
process. This differs from al other processe.
heretofore introduced into the Colorado
mines.
1 will state that from assays that have been
made by practical assayists, of the amount Of
gold the different quartz contain, and tha,
obtained from the same specimens by the pro.
cesses Of stamp and crushing mills and re.
torting that not more than 25 per cent. of the
gold can be obtained from quartz. But was
told BY the intelligent and gentlemanly Super
intendent Of Lyons Co.'S milling establish
ment, that by their process the taihngs from
the stamp mills yielded from $500 to 81. 600
per cord. Eight tons constituting cord.
If this be so. and have entire confidence in
the statement, who can doubt the superiority
of the Lyons process over all others vet
tiled.
l regarded it as a matter Of interest to as
certain the extent Of territory in Colorado in
which gold and silver had been discovered
and from the most intelligent and worthy cit
liens Of Central City. who have been resi-
dents Of the territory since ls59-among
whom | will mention the Mayor of Central
City, the Honorable w. NJ. Slaughter and the
Honorable J. F. Denver, member Of the
City Council, and the polite and courteous
landlord of the Conner House, who not only
furnished me with many specimens of the
gold bearing quartz and Galena ores rich in
silver, but who furnished me with the infor-
nation desired. From them learned that
in and about Blaekhawk, Central City, Neva-
da and Ureka. the following constitute the
principal first class Lodes: The Bobtai.
Gregory. Bates, Mammoth, Ground Hog.
Gunnell, Casio, Jo Cass, Ben. Holiday,
Sucker. Mat. Francis, Illinois, Rhoderick
Dhu, Gardner, Barris, Kansas, Americsn
Flag, Leo, Simons, Stake County, Boston,
Alps, Barker. Sap, Missouri on quartz hili),
Baker, Pewabie, King, Harsh, Shaw, CASTOR,
Missouri lin Russells gulchl quartz mill,
Nodaway, Salmon Z. Chase, Saratoga,
Hornet, and that in the gold district-there
even these we'll developed Lodes, seven
miles North OF Central City and in Lake
Gulch district one mile from Central, four
we'll Developed Lodes and that in Claw
creek county, South and West from Central,
which the towns of Idaho, Empire and
Georgetown are situated, there are thirty well
developed Lodes; and in Boulder county
there are fifteen we'll developed Lcdes; and
in Park county, foriy-hve miles Southwest
from Central, there are twenty FIVE well
developed Lodes and in SUNNI. county.
West from Central forty miles there are
many rich silver mines which have been re-
Gently discovered, and are called the Snake
River Silver Mines.
The rich Argentine Silver mines lie in the
county Of Clawcresk.
