VEIN MINING.

it is necessary to 60 deep on our quartz
veins, to properly develop their riches, is
now generally conceded. Washoe has been
good school" for the quartz miners Of
California, in which the necessity of deep
mining has been well demonstrated. -Four
years ago Grass Valley was about as dull as
Auburn is now, the quartz miners there ha'-
ing worked the surface rock, tourd near the
water level barren spots, and concluded the
veins had about give out, but the mining op-
eraions over the Sierras gave them "new
IDEAS" and now the rule is go down on your
ledge;" no richer quartz claims are to be
founl in the State than are now worked in
Grass Valley, in Amador county, and other
mining counties OF the State, where deep
mining has become the rule. According to
an eminent Mining Engineer, the great and
daily increasing value of mineral produc-
tions renders any light which can be thrown
upon the principles involved in the forma>
tion Of veins. and the working Of them very
essential. No miner should expect to find,
until the water level is met, the most pro-
ductive portion of vein; above that point,
irregular masses of ore may be obtained,
but no safe working estimate can be formed 8,
nor no reliable results reached until the
work has progressed under water. The

the most productive, as the experience of all
vein miners has proven. Before commenc
ing work on a mine well digested plan for
work should be settled upon and then never
deviated from. BY SO doing thousands Of
dollars will be saved.
The reason of unsuccessful quartz mining,
hereto fore, in our vicinity, has been the in
sufficiency of capital Quartz mining re-
quires an abundance of capital with consid-
eiabIe of patience and perseverance. No
mine can be worked successfully without an
expenditure Of many thousands Of dollars
And then there are so many delays that can
not he avoided, so many additional items of
expense that could not be foreseen, therefore
liberal calculations should always be made as

mine
Many Of the mines in Europe, Mexico, and
South America have been worked TO extra
ordinary depths and generally proved rich.
Humboldt speaks Of a number Of them over
1000 feet deep, worked for centuries and
aging Millions OF dollars. These are facts
that our quarts miners should bear in mind,
and be guided by, 10 developing their leads

presented the Editor Of the Vanguard with
ten shares in the Mammoth Quartz Ledge
Co. Of which James Ilaworth, Esqr., is Presi-

has. 1t would be just our hand, but we
fear it would take the whole Mammoth
Ledge to work them.
