THE MINES.

COLUMBIA HILI-From the letter of an
obliglng correspondent we CLEAN the follow
ing particulars:
4 3This vicinity has been dull for the past
| week and but little doing in the way of min
ing, owing chiefly to the filling up of the tail
fumes in New York Ravine, in consequence
of several companies washing at night with
out sufficient water to keep the fumes clear.
The Ditch Company furnished water to eff
feet clearance, and the rush carried off a
large portion of the false bottoms. All this
has been righted however, and operations
will be vigorously resumed. Another cause
for the apparent dullness may be found in
the fact that a large number of men who
were about the placeluneinployed for good
part of the winter, are now absent on the
Memphis race, which ,is-a portion of Weavcr's
ditch.
l see nothing 'discouragipg about 'G0lum-
bia Hill, but everything ito encourage the
perserering and energetic who are opening
claims. A'lmger quantity of gold dust has
been bought hepe than most spersons think
df the'exact amount oeuld be made public,
ut would astonish those who consider this a
poor mining locality. Week before last,
think, more gold was taken outthan in any
other week since the settlement of'the place.
Something like $4,000 was purchased by E.
P. Hubbard, Esq. The next clean up, prob
ably, will be about as large; and the time
| is close at hand when some large fumes
that are now being erected will swell the reg
ular yields far beyond this. Wm. Weights
flume, which is fortytwo inches wide, is be-
ing rapidly pushed through the ridge to the
Empire claims. Mcdonald brothers are put
ting in one of equal size, which will soon
be completed. The claims of these gentle
men and others adjoining are very valuable.
Here are few yields at various points in
this vicinity. Gwin & Co., of Little Grass
Valley cleaned up about $500 for a short
run. Saunders, Hannah & Co. cleaned up
ST 800. Curtis, White & Co., of Kennebec
Mill, obtained from a run Of Al days 5000.
Mccarthy Il Phillips, on Chimney Bill, re-
allied from short run $a00; Lucas j. Bran
ail, about the same. Many others have
done equally well. Wue-faurth 0f the Curtis
claims was sold this morning for S., ,5o0n
SAN juan HLL.-In the absence of de6nste
information as to recent gold yields in this
district, we will present few general state
ments showing the amount of wgrk being
done. The following companies are wash
ing: Bloomer, Star, Readshaw, Weiskittel
Co., Golden Gate, Winham Co., Eureka
Co., Sailor Co.. Brittania Co. and Lowe
Co.; in all ten. They employ about FIVE
hands each, use water to the amonnt of
probably not less than 1000 inches, or 200
inches to each, and realize from each run
OF eight or ten days from ST 900 to 5000
worth of gold. The depth of bank, washed
entirely By the hydrulic process, varies from
so or Is to $50 feet, and will be as much as
200 feet in some instances, when taanels are
completed SO that the Garth can be piped off
even with the bed rock. The following COM
panies are running tunnels through the rim
rock for this purpose; Star, Golden Gate,
Eureka, Sailor, Ohio, and Wyoming. These
tunnels are all being run on contract, mostly
by Welshraen, at an average cost per iiaeal
costing as high as $40. The Knickerbocker
Company have recently completed a tunnel
which has been under way more than four
| years, and have raised a shaft to gravel-
Each of the above tunnels employs about
four men, who work night and day, two at
time. The dull echoes of their subterra-
mean thunder often startle the costly sleeping
citizens in the village near by. There are
numerous sets of claims on the hill beside
those mentioned-indeed the entire number
is between fifty and sixty. Some are opened
and temporarily idle for various causes, some
partly opened and some quite untouched
The total number of men actually at work
in the diggings is probably near $50. Their
labors give employment to iron workers,
Observation-Disclosures wagon makers, carpen-
ters, blacksmths and lumbermen. All the
sawmills in this vicinity are kept busily go
ing Clark Johnson's mill runs night and
day, and cannot keep up with the orders for
sluice lumber.
HuMBuG CANos.-The hydraulic digglngs
opened at the various spurs putting into this
Canon are yielding handsomely. Haskell l.
Co., on Manzanita Hill, lately cleaned up
$1,000, after washing FIVE days and four
nights-expenses comparatively light. 1r-
WIG & Henry, at Villa Rica, have done
equally as WELL
A FINE CoNoERT.--The pupils and friends
of Mr.. Auguste Wettig, the accomplished
pianist and teacher of music, propose to ex-
tend to him the deserved compliment o.
benefit concert on some evening two or three
weeks hence. The gentlemen of the Sang
Verein, or German Glee club, will contrib
ute their services and make their first ap-
