IIowland's Rotary Steam Quartz Mill, in
twelve horse power, running twelve stamps.
Almariu D. Paul is the Superintendent. BY
process of amalgamation in battery. it saves
from sixty to ninety per cent The pulp flows
from the battery on broad tables-thence on
to three other tables, each table sixteen in
ches in width and twelve feet in length. and
covered with copper plates-thenee over
quicksilver rifles, thence to set of drop riff
files to catch the surplus quicksilver. Blanket
washing is done as in the ordinary way. The
pulp is then put through the arastra. Con-
trarv to the common rule, Mr.. Paul does not
draw it off. He first works it in n soft state
and then amalgamates then lets it dry down
to consistency that will stand shovelng.-
This material is then carried to a machine so
constructed as to discharge it gradually under
a regulated shower bath. 1t then floats on
over plates and rifles, which completes the
process. This mill is working quartz from
various leads, the richest of which is the lie.
compton. For the month Of August, it clean
ed up as follows: 1854 OF. l6 o.; 23s OF. +;
1859 or lOa or ; total 7O4 or. equal to
$50 pounds of gold-all from the Lecompton
lead.
A railroad from this mill runs mile up
big Deer Creek, and taps Lecompton, Buch-
anan, Hanson, Jacob, Beach's, and several
smaller leads The machinery has been in
use twenty months, and stands well. For or
der and cleanliness this mill is equal to a silk
factory, and is a pattern that many would do
well to initiate. 1t crushes from twenty four
to twenty eight tons in twenty-four hours
Empire steam Quartz Mill, Grass Valley
is of thirty five horse power, has eight stamps.
with sixteen feet arastra, eight Bradford
separaters and grinder. The amalgamators
are of RUSS Improved. The mill is owned
by the Empire Quartz Mining Company. 1t
crushes twenty five tons per day. This Com
pany are now commencing new mill upon
a new lead on Ophir Hill. They are crush
ing quartz freely from Ben Franklin, Boston
Rayine and lone leads.
For the above information we have the au-
thority of Mr.. Frederick Jones, one of the
proprietors.
AS for the other mills in this vicinity, they
have plenty to do and are likely to have for
some time to come, the leads appearing to be
inexhaustible.
The Nevada Quartz Mining Company, at
Nevada, own the American Hill Mill 1t has
an engine of thirty five horse power, running
twelve stamps, one Chill Mill and one aras-
ira. 1t uses galvanized copper plates, with
blanket and quicksilver rifles is using also
Banham's Pulyerzer, patented in May 1859,
"a new concern,-an1 the chemical bath
1t crushes from twenty to twenty five tons
per day, at an average of S25 per ton.
Mr.. J. B. Lowe, of North San Juan, has
patent hydraulic distributor which is well
worthy of notice 1t is a square iron box,
with four sluice gates placed at the cardinal
points, and SO constructed that one or all can
be opened 1t is for the distribution of water
through hose and for use in gavel diggings |
Mr.. Lowe has also invented a water tight |
coupling for hose.
The value of gravel diggings can be known
at the cleaning up, it being the system to run
the suices for several weeks at time To
prevent them from being robbed, night
watches are regularly kept.
To return to Mills,-Gold Hill Mill, at
Grass Valley, running five Chill Mills and
twenty one stamps, has double low pressure
engine, balance wheel twenty-four feet in
diameter, three feet stroke, three feet cylin-
der, and is hundred horse power. 1t uses
blanket tables and Atwood's Amalgamator
A cylinder armed with spikes constantly
keeps the pulp in agitation, thereby COM
pleting the amalgamating process 1t works
rock estimated at 5000 per ten, and crushes
from forty-fve to fifty tons per day.
A new invention for gravel diggings is
Briggs Perforated and Impregnated Blocks,
for the false bottoms of sluices. Several of
these may be seen at Cherokee. Amalgama.
tion takes place by friction, the blocks being
worn away by the gravel and sand and let
ting the gold and quicksilver down upon the
false bottom. The blocks are perforated in
the first place with numerous little indenta-
tions which hold the quicksilver and thus
cause the blocks to be thoroughly impregna-
ted. This invention, (Which is new one,) is
working very successfully and saves a large
amount Of gold previously wasted.
At our next District Fair we hope to see
models of these various inventions and i'm
proyements on exhibition.
WARRANTS have been issued for the arrest
of several merchants at Victoria, on the com
