An immense lead Of auriferous quartz has been
discovered In the vicinity Of DowDieville, high up
in the Sierra which has been traced ia direct line
for upwards of twenty miles; in every portion of it
gold has been discovered, and in quantities which
indicate extreme richness 1t is said that nuu,-
Der OF companies haze been organized for the pur-
pose OF working it at different points.
AT Geld Hill, in Grass Valley, one lead Of quartz
presents remarkable appearance; the stone 10
split up in every direction by assures, and wherever
an opeLing occurs, the surface Of the rock
covered with thick coating OF SCOT, which rub,
on easily The action of fire is visible in every di-
rection.
In almost every locality in the Northern mines,
quartz veins are being prospected, and machinery
erected, but our limits will allow as to specify
iurther A few words, however, must be given as
to the general results.
These mills are capable of grinding G ach from
eighteen to forty tons daily, according to their
power, and each employs about thirty men. The
general reports are that the stone pays from two to
two and half cents per pound, which would make
return OF from forty to fifty dollars per ton. Ii
these rates could re realized, there could be no
doubt fthe enterprises paying well particularly with
the chances Of richer spots occasionally appearing
but after very minute nvestig ation and question
lug repeatedly persons Of all grades connected with
the various esta blsbments; after collecting aad
comparing the stated returns OF all parties, have
been forced 10 the conclusion that quartz mining as
general thing, does not, and, for considerable
time 10 coue, will not pay. That the leads Of
quartz rock will eventually prove source OF uu-
told ricEes, we do no. doubt; but we feel con-
WINGED that at present the returns not over FIVE
per cent on be capital invested, even in those rep
resented ss doing the best, while in others posi-
tive loss is involved Although throughout the
Northern mines the veins very regularly, the
expenses are very great, AMI the machinery any,
thing but perfect Six months will not pass away
eeiCfe, with many who are rushing into quartz
nlA.ug on credit, with insufficient and patchwork
machinery, expensive labor. Sc the bubble will
burst, and ruin be entailed on not fs who are
now c0asidered ri:h in the possession Of CLAIM
We know tba, position is adverse TO th 1T usual
y taken at the present time but i. i Tie result of
very close inyestigation and long study.

We are indebted TO George Kerr OF San Joaquin,
FOR an account of fatal Iencontre which took
place yesterday, between the marshal of San Jose
and his posse, and a number OF Mexicans in the

was Mr.. Crane, went out to serve pro,sss on some
Moxicans belonging to The Almaden miaes. The
latter declared they would rot be arrested ard, as
the marshal and his party advanced, plasod them
selves in position OF defence, and wsrned them
against approaching The party continued TO al
fred. killing Mr. Whitman and Mr.. Crane. Two
of the party have since come in; the other is miss

mcrDiDg, n number OF citizens were preparing TO

sequerces were expected, as the Mexicars had
Themselves. Much excitement prevailed al San
