Dr. Behr exhibited a sample of coloring
matter obtained from an insect of the cyclops
species—one of the branchiopods—which is
found floating in great abundance, like a
thick seum, on the surface of alakein Marin
county, and probably elsewhere in California. The color is a bright scarlet, insoluble
in water, and unaffected by light or warmth,
but soluble in aleohol and oil. The doctor
thought it might prove valuable as a dye
stuff, and said it could be obtained in large
quantitics. Adjourned,
STEWART'S NEW GRINDER AND AMALGAMATOR.
Among tho receut new and promising inventions we have now-to mention Mr. J. H.
Stewart’s hinged muller plate grinder and
amalgamator, which the inventor informs us
is already being adopted into successful use.
Our artist has furnisbed the accompanying engraving, which well illustrates the
machine in a small compass. Its bottom is
perfectly flat. Tig. 1 represents tbe general
appearance of the pan. The revolving muller plate, EH, in a five-foot pan, is made only
six inches wide and three inches thick, On
the under side of the muller plate are twelve
grooves, each six inches long, three inches
wide and two and a half inches deep. Into
cone being thin euables the steam to have a
more <lirect effect in heating the pulp,
The inventor, who has bad ten years’ practical experience in quartz operations, says
this pan will reduce ores cheaper and quicker .
than any other made. He claims the following among other advantages :
“Ist. The muller plate being made small
reduces the amount of power consumed in
throwing the pulp, at least one-half.
“2d. The pulp has a much better opportunity to circulate and come fairly under
the shoes, ou account of the limited surface
presented by the muller. :
«3d. The shoes being attached by an adjustable hinge joint, midway of the shoes,
the bottom wears down even with the dies
also. This isan important accomplishment,
attained in theory only by other pans, while
. this one does itin practice.”
these grooves are placed the hinges repre.
sented on the ceuter of the grinding shoe, .
These pans are manufactured at the Miners’ Foundry, First street, where Mr. Stew8TEWART’S NEW GRINDER AND AMALGAMATOR.
F, in Figs. iand2. The groove being concave, and the hinge of the shoe convex, it is
allowed to swing up and down, while it is
rigidly held from swerving to the right or
left. A small key, a, holds the shoe in place
when the muller is raised. The shoes, F,
are twelve in number, and are made fifteen
and three-fourths inches in length by about
twelve inches wido aud two anda half inches
thick at the outer edge, and one and a half
inches thick at the heel or inner edge. The
muller revolves from right to left, as you
face tho engraving. The upper part of the
shoes project forward, so as to force the
pulp down between the shoes and the dics,
The flanges, D, are for the purpose of directing the pulp to the center. The lever, H,
is used for the convenience of lifting the
muller expeditiously from the dies whenever
desizable.
The cone in the center is proportionally
large, being two feet in diameter and eighteenincheshigh. This gives the space within
the inner line of the grinding surface alarger
radius than in most pans, obviating the
cleaning up of a large portion of grinding
surface, which, from its limited circle, is
generally the least effective. The steam
chest underneath the pan reaches from
about the center of the shoes to the cone,
whicb latter forms a part of the chest, The
art will take pleasure in showing miners
and parties interested in machinery the chief
principles of his invention, and furnishing
further information.
Exrrctse.—Nothing is more invigorating
to the constitution than judicious exercise of
the muscles. The great cause of general
debility, so prevalent among residents of
crowded cities, is mainly due to a lack of
proper exercise. The introduction of street
cars has, doubtless, greatly added to complaints from this source, as thousands who
were formerly in the habit of walking to
and from their places of business, are now
tempted, by cheap fare and convenient carriages, to ride; thereby neglecting one of the
greatest promoters of health, in their accustomed walks. No person can enjoy health
without exercise of some kind. Sedentary
people who will ride, should accustom themselves to regular gymnastic exercise of some
kind or otber. All such in this city would
do well to patronize the San Francisco
Olympie Club,
Ausrnanian Goup—Grerar Increase or
Yreiv.—The reecipts of gold from Australia
appear to bo seusibly reviving. The reeeipts for September last wero $3,433,885,
against $1,192,780, for the corresponding
period of the previous year, For the nine
months cnding with September 30th last,
the value of the gold imported from Australia was $23,196,855, as compared with
$10,776,160 in 1865, and $12,108,310 in
1864. In this connection it may not be
without interest to recapitulate the Anstralian yield of gold for the past eight

From present appearances, the total yield
of 1866 will considerably exceed $30,000,000 ;
perhaps reach the yield of 1862—$33,523,765. This large and unexpected increase
for 1865 and 1866 is most remarkable in its
occurrence, as well as important in its comj mercial import. We are not advised how or
where this extraordinary increase is derived.
THe despondengy which pervaded the public
mind of Australia in 1864 is now happily
removed, and the United Australian Colonies
bid fair to again prove formidable rivals to
California and its neighboring States and
Territories in the yield of the precious
metals.
Cazrrornra Oaxs For Wine Casks.—Dr.
G. B. Crane of St. Helena, Napa county,
has made a nine thousand gallon cask from
native oak grown on his place. ‘We can assert on his authority, that as good oak for
wine cask staves can be found in Napa Valley, as can be imported. Dr. Crane commenced his vineyard in 1859, and has made
thirteen thousand gallons of wine this year.
A writer in the Jimes advises the concerted action of the public press in familiarizing the people of Nevada State with the necessity of changing their name to ‘ Washoe.”
“To leave it to the Legislature,” he says,
“-svithout snch preparation, is to allow it to
go by default.” The name is not only a misnomer, the State not being particularly
“snowy,” but it leads to constant confusiou in connection with the California
county and city so named,
Rep Kerosenr.—An article called “‘red
kerosene”’ is being introduced into the Hastern market, under the specious pretence of
its being an inexplosive product from petroleum. Itis useless to say that it is merely
a “dodge” of some oil speculator, by which
to palm off a very inferior articlo at a
higher price than a really better article of
ordinary keroseue. The “‘red kerosene” is
merely the ordinary article colored, for the
purpose of carrying out the deception.
Drivipenps.—The following monthly dividends have been declared: Crown Point,
$100 per foot; Hale & Norcross, $150 per
Tes Paris Exposrtion Coamuorres.—A. share or $100 per foot; Empire Mill and
meeting of the California, Committee in the . Mining Company, $10 per share or $160 per
Paris Exposition, will be held at their usual . foot; and Imperial Silver Mining Company,
place of meeting 418 California street, at 3} $8 per share. Crown Point carries overa
o’clock Pp, a. to-day. ‘ balance of $36,000 to next month.
