vices in the milling and ore working
line originating in this State, especially
for the saving of tho precious sulphurets
aud quicksilver running to waste in the
tsilings of our mills, we have seen none
which has attracted our attention like
one We saw being tried at the Rhode
Island mill in this. town yesterday. 1t
is the Corrugated rifle and concen-
TRAITOR" invented by Mr. George r. Ev-
ans, OF Virginia City. This recent in
vention is just now being introduced,
and from what we saw Of it We should
judge it 10 be a very successful and val.
liable institution. II consists of W.
shallow boxes, about six inches deep,
two feet wide and five feet long. The
bottom Of the lower box consists Of \
series of conesve wooden rifles six
inches apart and three or four inches
deep. The upper box bottom consists
also of a series OF rifles formed of u
corrugated sheet of copper, the corrugH-
tions being three inches apart-S series
Of hollow and round - after the
style of the sheet-iron houses so famil-
lar to all Californians. Every other
hollow has q narrow slit at the bottom,
an eighth Of an inch wide, extending
nearly from side to side Of the box.
The tailings and water flowing over these
corrugated copper rifles, q perfect eddy
is formed in each one, continuous
throughout the series. Thus the lighter
particles pass of and the heavier are
gradually collected ut the bottom
Of the rifles or run down through
the narrow Sits before mentioned into
the larger rifles in the under box,
whence the collected quicksilver can be
drawn of and the rich sulphurets re-
moved as often as found practicable or
sxpedieut. The copper rifles being
.smalgamated by the quicksilver, also
collect much drifting amalgam.
Mr.. D. P. Pierce, the Superintendent
of the Rhode Island mill, has long since
adopted the sluice and blanket style of
saving the sulphurets and quicksilver
passing off in the tailings Of the mill
which reduces at the rate Of
sixty tons Of Crown Point ore per day
saving by this arrangement, per-
haps ten pounds Of quicksilver out OF
the usual loss Of between 10 and 100
pounds per day for that quantity Of ore.
He placed this set Of Evans rifles ut the
end Of the blanket s~luiccs, so that the
tailings passed through them after the
blanket sluices had had their full and
usual saving effect, and the reSnlt dn-
ring the two days no has used them
would be astonishing to any one. lie
found such q great quantity OF quick
silver in these new rifles that he was
fully convinced there was u leak some
where in the mill process. He therefore
st once proceeded TO clean out the pans,
and after close examination At every
point was satisfied that no unusual leak
or disarrangsment existed. He then
made another run of twelve hours with
these rifles attached Nsetting them al
the slight inclination of an inch to the
foot. Tho result he showed us IN three
common water pals full OF heavy rich
s%ulphurets, saturated throughout with
little ~globules Of quicksilver OF all sizes,
while ut the bottom Of each bucket was
= pool Of the bright metal. There must
have been at least 25 pounds of quick
silver in these three buckets, TO say
nothing Of the sulphursts. The quick
silver, too, Of course contained q con-
siderable quantity of a~malgam.
Such q saving of quicksilver alone,
aside from all other considerations, is
enormous and Of the greatest practical
Importance. This would be At the rate
Of so pounds per day, which would
otherwise inevitably run to waste-sn
important and highly interesting item
to all mill or mine owners, the usuaI
loss Of quicksilver to the ton OF ore re-
dussd being from one and n hHlfto three
pounds.
That peculiar fluid metal sickens,
and therefore passes of with more IA
cility under certain circumstances thar
others, therefore the general consump-
ton or loss of it is far greater thai
people generally have any idea Of. Mr..
Pierce considers this set Of rifles y Ut.
tie too wide for that mill, aud that con-
siderable advantage could be gained by
making the series or boxes q Few feet
longer, but these arc points and matters
easily arranged aud accommodated.
Whether Evans Rifle and Concentration
will eventually do away with the blank
Vt sluice arrangement now so generally
in vogue, remains for actual experiment
10 decide we are satisfied, however,
from personal observation, that the in
ven,ion is Of great practical and oovi.
Gus value as applied to the saving OF
the precious metals in the tailings from
mills, after all other usual means and
appliances are exhausted, thus making
the yield per ton Of our ores consider
ably greater, and obviating the long
existing and perplexed question OF loss
in ~tsilinys to u very considerable de-
gree, The invention is certainly a very
important one, and as such will COM
mend itself to the special attention OF
mill or mine owners, and all other prac-
teal observers.
"EAsr LYNNE" To-NIGHr.-rhe very
popular sensational drama of Fast
Lynne" will be produced this evening
at Piper's Opera House, in the very best
possible style-Miss Lucille Western
p~ersonatiug Lady Isabel and Madame
Vine. Mr.. Herne will pcrsonate Archi-
bald Carlyle. Appearing also in this
piece, as new additions to the company,
will be Mrs. Stewart, the popular stock
actress, Mr.. aud Mrs. L. F. Beatty, Billy
Robinson and wife, Dennis aud Cald-
we'll, making one Of the best dramatic
companies which has ever appeared on
that stage. Heretofore the pieces pre-
sen,ed have given Miss Western little or
no opportunity to exhibit the high de.
dres of dramatic talent she is reputed
to possess, but in "EaStLynne" she APP
pears in one Of her specislties. No en-
ira charge for reserved seats.
