from the KANSAS mines thus describes
tho process obtaining gold from
quartz:
Tho mill most in use horo is tho
stamp mill, somo numbering six, and
from that up to twenty stamps
each, placed in n row, divided into
apartments of thrco stamps, which fall
into one battery. The stamps arc
round six inches in diameter and four
teen inches long, with feet of chilled
iron or stoels these coming in CON
tact with tho quartz soon wear out.
Tho stamps are attached to stems about
eight feet long and two and half inches
in diameter; while two or three feet
from the top of the stem collar is at
tached, circling tho stem, and about
tho same diameter of the stamps. The
| stamps are fastened in frame to work
up and down, and back of the stems
| there is horizontal shaft to which tho
| cams are attached, which, us thoy
| revolve, takes under tho collar and lifts
the stamp tho required hoight, genc-
| rally about fifteen inches, thcn the
end of tho cam passes from undcr tho
collar md the stamp falls, crushing
tho quartz. Tho shaft rovolves about
thirty times II minute, lifting each
stamp that number of times A twenty
stamp crusher will strike ten blows II
second.
The battery is of iron or wood, gon-
prDllv ubpuf thr.n G.,t lnn,. an, c,,t
wido and two feet high-n square box
form. The back side of the battery is
open from the bottom to height of
seven or eight inches, and over this
opening screen of perforated sheet
iron is securely fastened, and through
this, screen passes I'LL the fine quartz,
gold. etc, OH an apron of wood, about
three feet sduare. The upper part of
this apron is plated with copper sheet
ing galvanized, below this there uro
grooves running the length of the
apron, filled with quick -silver-cut
slips those grooves are called somo-
times, resembling II window blind
opening towards tho mouth of tho bat
terry: Below tho apron is tho sluice
box, 3 feet wide, and the sides about II
inches high; the first joint of tho sluice
is shaped something like tho letter II,
three feet wide at tho top, tho width of
the apron and decreasing in width.
One half the bottom of this box is COW
cred with galvanized copper, tho rest
of the suico is long marrow box,
eighteen inches wiao, fourteen deep,
and of indefinite length, the longer tho
better. Across tho bottom of this
sluicc thcrc are small bars Of wood
placed on grooves, cut, after perforated
sheet iron is placed in them, un half nn
inch from tho bottom. Frequently ri
the end OF the sluicc, IL small box il
PLACED, Containing quick silver.
The mi,l Is put in motion, the quartz
is shovelcd into tho batteries from the
front side; it is soon pounded into Il
powder II gallon and half of water
per mn rtc flows into tha bnttcry: Il
tea spoonful Of quicksilver is also put
into the battery every half hour-@ This
collects the gold and amnlgnmntcs it.
Whom the quartz becomes fine, It
splashcs through the screen into tho
apron, the galvanized copper plate col
lcCts II portion Of the fine PARTICLES Of
gold that comes in contact with il, and
retains it securely fastened TO It's sur
face. Some, Of course, pHss over, uud,
If not caught by the quicksilver i'm tho
grooves in tho apron, it falls into an
mother galvanized copper shut in the
sluicc whore it is retained; if not there,
the rifle bars Will mako IN effort to
stop it, and as Inrt resort, the quick
siycr bow at the end is rcady. Fit
passes that, it is gone.
The generally run tho mills n week
before cleaning up. Then the bate
rics are cleared out, the aprons scrup-
ed, the quicksilver and gold taken up
together, the copper plotcs all scrapcd
Of the nmaIgom, the rihIc bnrs arc OK
nmincd and cleaned, tho quicksilvcrbo box
nlso examined ; then the cOnglomcratu
mass Of quicksilver and gold * put
into piece Of burkskin and the loose
quicIl-ilvc strained through and retain

taken from the buckskin, and put into
