amalgamation, and several comp MES working
their ore solely for the free gold little specks OF pure
gold found in the ore leaving the other steria for
future reduction when silver WORKS established. IL
must Of course be very rich mineral that will ray for
this system of working. Tie separation OF gold from
the ven-sone is a cheap and simple mechanical opera
ton understood by bdy, whereas the separation
of siyerfrom its ana gangue is expensive complex
and che uieal, and understood by only few inls
waseful policy Of working the ore twice is likely
TO be pursued for year or two.
As for the amount Of ore now taken ont, or the
amount of silver obtained is difficult obtain inor-

from wahoe arrived in SIN Francisco. There are
sbout 900 men il WashOe, and half of them may 10
employed in hard and regular labor in opening shafts
aud tunnels many of which however will never Prove
Of the slightest value. TIE rich silver mines all

Mace in Gold Canon is Gold II H. where the claims
of aurferous quarts and thence 10 Silver City the au-
rrerous quartz nbounds all along the canon The gold
in a il quartz is mixed with srge proportion OF silver
and many persons suppo that at depth Of lOO feet or
more the silver will become the predominant metal ana
found with the gold in metallic form.
Washoe ia in latitude go 30. One hundred miles
further south and on the side Of the mountain,
but within the limits Of California and half way be-
tween Mono and Walker Lakes, lies the Esmeralda
mining district The mines ofthis place were found ON
the I'D of August ast by j. 81 Gerry, formerly OF Ox'
ford, Ohio The main lode, called tie Esmerads pro-
iects in places twenty feet high and twenty Wloe
above the adjacent land Like the Washoe ore, this is
sulphuret of silver. There $ uniformity in the ores
of these two dis rcts rarely if seen elsewhere Or
dina,y every little vein has it's peculiar ores,
which are recognized at by the experienced miner
wherever be nav see them. But in Esmer1lda and
Waboe all the eres are alike in character suphuret
which ia rich ard easy to work. Tie quantity Of the
suphuret varies greatly in different parts OF the VEIN
stone but the ore itsel is the same. Some VEINS con-
tain much free gold and little particles Of metallic sill
yer; Others have none. There about 500 miners
in Esmerasia, but they have yet done very little at
opening mnes, and nothing ut sll in reducing ores
The Coso mines are alo IN California, about Az miles
eastward Of the baee of the Sierra Nevada, IN
latitude So 3V They discovered in October last
and ls.e Is known Of their value. There are no per-
manent residents on the ground yet. Coso is l2O
u,il.s from Vsslia, and 300 miles from Los Angeles
potosi is in the roulh western corner II New-Mex-
co between The Colorado River and California, IN ati-
tn2e So 81 and Longitude 1852 so. The distance Ia
about 80 miles from Los Angeles with which the place
viii do it's trade, if ii has any. Poos was discov-
cred in the middle Of Last Winter. Both Pot 81 and
Coco are reported be exceedingly rch but there ia
| 40 much living about MINES that nobody knows
what 10 believe when the reports are irst published.
Several persons who have lately returned from Poiosi say
there are no rich veins there aud others from Coso say
the odes In that place be wrought 10 proht
because il II IN the midst of desert where there ID
neither water grass nor wood great many persons
have gone 70 potosi Of late, bu, only few have re-

TIE Arizona mines are spread ont over large ex
tent of country and have been wrought for many years
The STANDARDS mined there extensively ia the middle
the century and two of its miues the Arizona an
Panchss dc Plata tplanks Of silver were reported L
be among the valuable mineral deposits OF Mex
ico The exact position of both these mines has beel
lost. the Indians having driven away the mnen an'
held possession of the country Dg that all Of thos
