took out after short run $7O3. Moore 4
Readshaw's last washing yielded Sl,175
The Ohio claims produced Sl,336 so; Win.

this vicinity which largely swells the aggre-

sufficient prominence to warrant special men.
ton. The weekly purchases of dust by the
different buyers reach very high sum, and
are larger now than they have been for some
time. An accident occurred on Thursday
which may possibly retard mining operations
slightly. The Middle Yuba Ditch broke al
place about half mile above Hess Point
and some forty feet in length of it was wiped
out by the escaped water.
Shady Creek.
One good yield reported from the dig
gings on this stream. Stevens & Co. cleaned
up Sal. Shady Creek has been worked for
number of years, and has contained many
spots of considerable richness.
Montezuma.
The Irish Company at this place lately
took from their drift claims the sum of 1852
Mississippi Hill.
We give this name for convenience sake
to that magnificent gravel range which ex-
tends from Sweetland Creek to Junction
Bluff, a distance, following the trend of the
river, of about a mile and half, having a
width from quarter to a half mile 1t has
generally been called Manzanita Hill but as
it lies in Mississippi Valley District and there
are several other Manzanita Hills in this Vi
cinity, the name given it above would be
much better, and should be adopted. Mis-
sisippi Hill is no doubt as rich as any other
hill, or spur of the ridge, in this section
The claims fronting on Sweetland Greek
open directly into it, and have been known
for their richness since 1853, the bed and
banks of the creek having been worked long
before that time. The bank is very deep,
and resembles the gravel on San Juan Hill.
A good part, if not the whole of the hill is
claimed, and will ultimately be worked An
association of claim owners for the purpose
OF putting in one large main tunnel, is an
enterprise that we wonder has not been at
tempted. 1t would give immediate value to
the ground, and enable it to be worked at a
comparatively early day. Miners everywhere
will one day find it to there advantage to
consolidate their interests and work together
Such mode would prove most economical
and far more profitable than the present sys-
tenn of small, isolated companies. Now,
every set of claims, nearly, has to run its
separate tunnel, and the other expenses
amount to much larger aggregate in pro-
portion to the amount of gold extracted than
they would if several companies should COM
bine.
Freem ans Crossing.
Bart l. Madison cleaned up in their
claims on Sierra Bar, after weeks run, over
$500, netting them S27 day to the hand
The claims of Parker & Co., adjoining, are
paying at the rate of $l7 per diem to the
hand. Both companies have to remove large
accumulations of rock by manual labor, but
are preparing machinery to lift them out by
water power
GUANO ISLANDs.-The number of puano
islands now claimed by American citizens
as recorded at Washington, is forty-eight
These are all to be surveyed and charted
and the quality and quantity of the guano
thereon, to be ascertained by competent an
