The results vary much that average should be

for the obvious reason that are not willing thas
their private business affairs should be investigated
TIE question Of profits might be made OF bankers
and merchants with IS much proprety. The best
evidence have of their prosperity is that nearly
an the mills have paid the cost of erection amounting
to from $40 900 to SO 900 more, for opening their
mines and paying for leads, amounting n some
csses to from $40 600 to 900 MORE with all expenses

mills.
"The Empire Company has declared dividend Of
one-ha per cent per month their capital Of 500 ooo
and the Mount Hope Company have paid one dividend
Il one per cent per month their capital Of 900
before their new null, just completed, was put into
operation. The Allison Ranch Mil is owned by sir
men. who are all at work in their own mill Others
would have declared large dividends but for their out
laws in opening their Mines building force pumps "
free their mines from water &c. The veins not
worked at greater depth than $50 feet yet except
the lead on Osborn Hill, owned by the Grass Valley
Quartz Mining Company, who have pushed their shaf
to depth of 30 feet. majority of tho veins have
not been worked over from 50 10 100 feet in depth
As general thing it is observed that the veins pay
better at the greatest depth vet reached than nearer
the surface though in veins the outcrcpis rch.
"The surface diggirgs in aud about Grass Valley
have been partially dug but the great want Of water
the two past seasons has materially essened the
amount of gold which otherwise would have been
taken cut Dggngs which were supposed % have
been worked out by those fret working them have
been worked over again. and have paid with the i'm
proved mode of working nearly as well as at first.
The beds q creeks have been repeatedly and are st
being worked over-in every case probably. The
amount of Placer dust sold here through the Fall,
when but little water could be obtained, 10 about
as. OGO per week With plenty Of water 1t would
probably reach $50 600
MEN get not less, on ar average, than - per day,
who work faithfully though, as in all mining, many
get less and 1t has been discovered that
the hills around Gras Valley contain ,ch deposits al
great depths. One shaft sunk on Alta HlD to depth
of two hundred feet at an expense OF fiooo struck

cbnery erected for hosting the dirt vi. pad Tor In
lees than six months end the propreors are IN lar
wsy of getting rich. Other shafts are either COM
merced or are in contemplation.
"The wages of laboring men are % per day, and
need not cost over 81 per cay for good and comfortable
board. Indeed many of the boarding houses charge
but "a per week for board So far from the mines be-
ing exhausted it Is the prevailing opinion among miners
both of quartz and placer, that only the surface
touched and that than one generation must pass
before any sensible dimnuon Of the gold viii be APP

deposits are not yet reached.
"Tbis opinion pre- dcated upon the resuh OF deeper
| diggngs and more scientific and thorough mode OF
working the mines.
There are but few bitches In this locality. The
| priDcpsl onts the Empire Ditch, three and hal
miles long oottng sbou, $40 900, and Murpbys Ditch
two and half miles long, cost about 80 OOO and the
Union Ditch about four ard half miles long, which
cost about 900 The two first pay about pei
cent per month on their fret cost the latter have
not been able to ean but presume il pays the same
as the others. Within two miles of Grass Valley,
there is large extent Of country which has not yet
been poepeced and where indie .tons Of gold deposits
are quite favorable any which have been opened
but it will not be long before /; will be done. All
that is necessary is for energetic man TO 90 into
new place prospect the grould thoroughly, and II he
is successful in striking lead, he is to have o.
many neighbOrs he desires in Incredibly short
space of time. Up TO this time, public attention has
been turned in another direction for The time being.
