The Mining and Scientific Press,
SIMPLE BUT EFFEOTIVE.
At the present thae when the wholo mining
interest of the State is suffering from the
effects of n well founded compluint that the
cost nf extmeting the metuls from their ores
leaves but a small inarzin for profits, in consequenco of the insufliviency of the processes
employed for their extraction, the discovery
of any inethod or any nuchine that will re
move the cause of this complaint, becomes n
matter nf grent importance, net only to those
directly concerned in mining operations, bnt
to the people of the Pucific coast generally.
Buux’s first premium Separator nnd Amulgamntor is, by many, regarded as the neurest
approach @® perlection,in this requireueut,
yet introduced. Simple in its operation, constructed on principles the sunndness of whieh
are apparent to every one competent to compure the cause of un action with its effect, its
results aro demonetrative of its efficiency.
Thongh but littlo moro than no yeur since first
introduced, it has been thoroughly tested in
varions purts nf this State and Nevada, ond
with every description of ore—from adaimuntine quurtz, containing coarso gold, to the difficultly manuged tight sulpliurets ond elilorides and other complex ores of silver; and in
every place where it has been nsed, we are
told, ithas given the fullest satisfuction—to
the validity of this claim the increasing orders
for these pans testify. We think nothing
more conclosively demonstrates the correctness
nf the principle on which Banx’s Separator
ond Amalgamator is constructed, thun the
fact, which is so very opparent at the present
exhibition, that while nll the best of the pans
—tbose made by the most famous inventors—
have been changed more or less to eonfurm to
tho principles forming the ehief charaeteristie
of this invention, nomely, to prevent the merenry being ground with the ores. Baux’s
Sepurator und Amalgamator remains unchanged in every essential particular.
It is claimed for Mr. Banx, who is a learned
French mathematician and machinest, who
first demonstrated the ndvantage of retaining
the mereury on the onter edge of the pan—
and by the centrifugal motion of the mullers
to inject the particles of metal into it for
amulgaimxtion, a principle so correct ond effec.
tive thut the wonder is that it bad never been
discovered before.
We lave made many inquirers in relation
to these pans, from millmen and miners in varions parts of the State in which they are in
operation, and the general reply has been that
they are what their inventorelaims for them—
one of the most simple and effective amalgamators ever introduced. In that section of
Nevada County in which are located those
ricb deposits of bard cement containing gold,
known as the blue gravel lead, many elaims
thnt could derive no profit by working this
coment with ordinary mills nud pans, are extracting large quantities of gold with Baux’s
Amalgnmator.
at Maltman’s celebrated chemical works,
near Grass Valley—where bundreds of tons of
sulpurets nre annunlly operated upon to ob
tain their gold by the chloriation proeess—tbis
pan has made tbe produet of tho operation
considerably larger. At Gold Till, Nevada,
where a number of these pans have heen used
for months—on trial in every case the millowners huve ordered sets of them—till at present the orders from Nevada nlone reach nearly
sevonty, Ata meeting of a number of millowners assembled for the purpose of testing
the efficiency of the vnrious pans ut present in
nse, Baux’s Amalgamator and Separator obtained two and one half ounces of amalgam
from 400 pounds of pulp that had passed
through a famous pan—whieh grinds the
mercury with the ore! Comment on sucha
fact—which may nt any time be tested—is
quite unnecessary, We ore not writing this
artiele to extol Baux’s Amalgamator and Separator beyond its merits, or to disparage any
other pnn, bot to eonvey information to our
readers on an important spbject, and ns an act
of justice to the inventor of a really valnable
machiue,
EDITORIAL BANQUET.
The Lixecative Committee of the Fifth Fair
nf the Mechanies’ Institute, anxious in some
manser to testify their appreciution of the etforts mude by the press of this city to advance
tho interests of tho Pair, extended to its representatives, on Mondiy evening, at the Pavilion,
agrund bunquet. Some thirty or forty guests
were present, exclusive of the Committee, and
inclusive of the members of the editeriul fraternity. Mr. Cherles M. Clin, President of
the Institute, presided ut the head of tle table.
Vhe Bedletin was represented hy Messrs. Snow
and Gross; the slaerican dlag by Messrs.
Bennett, Wilson, aud L.?. MeCarty ; the Cull
by Mr. MeGrow ; the Mixtse axp Sciextiric
Press by Mr. Ewer; the press ot large by
Messrs. Campbell und Bansiman.
At eleven o'clock, vr. ., the guests were
seated to as sumptnous and savory a repust,
we venture to sny, as hns ever been served in
this city on any oceasion ot all similar. ‘ho
caterers wero Messrs, Swain & Brown, of the
branch restanrant of the Pavilion.
After tho removal of the cloth, cigars,
“champagne and eogniac” were introduced.
The genin! influenee of these inspiring
liquids soon manifested itself. Gentlemen
who professed not to be eloqnent or gifted
with vocal powers, discovered that they had
somewbat nnderrated their own abilities. Sentiment, wit, eloquence, and song, were the conSequenee. Meysnred ntterance and frigid
courtesy were soou elinnged to convivial mirth
nnd enjoyment ; corks popped, glnsses rattled,
and the toast, the speech and the song, went
round uutil an hoor that might have been
termed decidedly late, when the eompany relnetantly separated with expressions of mntnil respeet—protesting officially, individuality and
collcetively, thut a more delightful occasion had
never been experienced, than that to whicb
the night and the generosity of tbe Executive
Comittee of the Fair had given birth.
Cipgr Vinecar.—Familics who make their
purehases indiscriminately, are snhject to have
impositious practised npon them of all kinds,
and in nothing more than the article of vinegar, of which there are many spnrions and
poisonons brands in the market, Mouriatic
acid, eombinod with coloring barks, in numerous instances, form tbe base of these poisonons vinegars; nnd when they are consumed
incautionsly, prodnee nausea at the stomach,
followed by vomiting, and it may be permanent
sickness, if not death, Tbe importance of
procuring vinegar in its purity, it will thus be
seen, cannot be overrated ; and in that view, we
cordially recommend ap article monofactured
by Mr. Wheeler Martin, southeast corner of
Second and Ioward streets, from pure cider,
as not only entirely innocent in its effects. but
nutritive, if-vinegar in any form can be said to
possess nutritive qualities,
Tur Recetets.—The gross receipts of tbe
Fair, ineluding Monday evening, amount to
$21,890.40.

Samples of this valnable article will be found
on exhibition near the large engine nt the Pavilion. In fact it is used in the very eylinders
of that grand motor. As we hnve before
stated, this packing is not a new thing, it baving been extensively nsed throughout the
United States, and is generally ackuowledged
by engineers, who have the most praetical information of its working, to be the best in nse.
It works well in the eylinder, with less friction
thau the old style of packing, never leaks, and
is easier adjusted. It is fitted in so as to leave
ho ridges, each piece lapping over the other.
The saving of fuel by tbe packing is great, and
as an important auxiliary to stenm engines
has a renowned reputation. One of its superior points is the fact of its fitting itself by
wire so completely to its position, notwithstanding any little deficieney which may exist
in the smootbness of the piston to which it is
applied. It is exhibited by Menry S. Sinith,
of tbe Goldeu State Iron Works, whose ndyertisement appears on our last page to-day.

HUNTER'S CONOENTRATOR, AMALGAMATOR AND SEPARATOR.
One nmong the first objects of interest that
nrrests the attention of tbe visitor to the
pavilion of the Fair, in the depnrtment of
unichinery, is the above-numed machine, invented by Mr. Andrew Ibninter, of San Francisco. ‘To ininers nnd millmen, it possesses
virtues which commend it in an especial degree, aad itis more particularly to the attention
of such that it addresses itself.
The udvantuges cluimed for this machine
over all others by its inventur aro: simplicity
of construction ; udjustability for all the dillerent kinds of metals, for line or coarse sands or
pulp; the complete separution of the sands
Irom the free gold and the snlphurets, each
being deposited in their proper place ; and the
suull pmount of power required to run them—
one-sixth of a borse-power being sufficient for
one machine.
The capucity of this machine is equal to the
working of seven tons of crushed rock per
day, being an amount equal to tho working of
n live-stanp battery. It saves all the sulphurets, free gold, and wasted amalgam, on its
eopper plates, without any appreciable wnste.
One enbie foot of tailings from the coneentrator, carefully panned ont by hand, gave onefonrth of an onnee of very fine sulphurets and
sands, which amount was fonnd, upon assay,
20 contnin two-filths of clean snlphurets; indicating that the loss of sutphurets per enbie
foot of tailings from tbe coucentrator was
about one-tenth of au onuee.
‘This maehine was patented May 28d, 1865,
and has been thoronghly tested in the Princeton Mill, working the full amount of rock
above mentioned, and furnishing in every purticular the highest satisfaction. The public
have 9, fair opportunity to ex:mine the splphurets extracted Irom the tailings at the
pavilion. Wo have been shown zine snlpborets from a hundred ponnds of tailings
sent-from New York to be worked on this
machine. ‘Ihe resnlt was certainly all that
could have been expected, and, as we are
asspred, met with the unqunlified approbation
of those who were having the test performed.
As Honter’s Concentrator, Amalgamator
and Separator is now beiug built, the plates
are two and a-hall feet wide by five feet in
length, giving twenty-five sqnare feet of eopper
plate in front of each battery. ‘I'hose who
are familiar witb the different processes of
working mineral-bearing rock, and have witnessed the results obtained by this machine,
have spoken of it in the highest of praise,
Our innumerable mines of silver, gold and
other valuable ores, enn only be brought into
the market and made to yield n profit by modes
of working which will insure a saving of all, or
nearly all, the minerol contained iu the rock.
‘There bave been a large number of maebines
before the public professing to attain this end ;
but trial has proved that they were inadequate
for the purposes intended, and they have been
abandoned. In faet, the history of fadlure
has so often been written that o piece of
mechanism of real merit now finds diffienlty in
finding lodgment in the public favor, This is
very natoral; bot the inventor of this machine
speaks with such coulidence of its abilities, ond
exhibits sueh ineontestible proofs of its superiority, that we are bonnd to believe it all that
it professes, and therefore hope that neither he
nor we, nor the world at large, may be disappointed. An amalguinator that will save twothirds of the gold or silver in rock, is a great
benefit; but that whieh will save all that is
otherwise wasted—as Mr, Hunter contends
this machine willis n positive blessing.
Visit FRow THe Scuoors.—The pupils of
severul of the publie schools made a visit to
the Fair yesterday. Mr. Stratton, who eomnmanded the hrigade (which numbered several
hundred children of both sexes), took oceasion, after forming the seholars in line, to address them a few words of cantion abont
handling the goods, and then led them to ofl
parts of: the spacious hall where objects of interest were to be seen. Aunt Susan, of the
New England Kitchen, entertained a portion
of the children at her tables, and had ocension
to compliment them on their good hehavior.
Cotrox Manxuracrunixe.—Speuking of this
bnsiness, the Newburyport /Jeraid snys it has
not been so good for a long time us uow.
There is nota spindle or loom in the country
that would not be pot in motion il skilled
lubor could be hud for that purpose. Some of
the mills in Lowell und other plices are ata
stand-still for want of help, and three Inndred
operatives nre needed in this city today. The
help cannot be had, though the mills ure sending runners all over the North und into the
British Provinces to collect them, unl weavers
earn a dollar n day, Weuvers nre most in demand; other departments cun more casily be
supplied. It is calenluted that one-third of all
the weuvers have died, been married, or otherwise pnssed ont of tho busine:s sinee the war
began, and thn factories lave cea ed teaching
others. Some have gone into the woolen
mills, or learned to run sewing machines in the
shoe, hat, and clothing factories, and others
huve been taken in othe: ways, so that not
more than linlf a supply enn be had. If the
, mills eould have help as the business now is,
tbey would soon make up for the losses of last
. Winter.
A Look ito re Fururr.—In the debate
in the Ilonse of Representatives on the Niagara, Ship Canal, Mr. Littlejoln eonctnded
his speech as follows ; “ Now, sir, twenty-five
or filly years bence, from the Atlurtic to tho
Pueifie, will be a continous tier of Stotes,
members of the Union, and over those States
will yun the iron horse of the Pacilie Railroad.
Members who reside on the fur western coast
have also an interest, theu, in this highway.
The produets of Asin, wafted over the Pacifie
ocean, and then by rail can be shipped upon
the waters of Lake Michigan, and pass to the
Atlantic by this great improvement, and the
mercbandise of Philadelphia, Baltimore, of
New York, of Boston and of Portland, will be
sent westward over these waters, and will find
a way to the eoast of the Pacific, and even to
China and India, for sale and consumption.
And not only tbut, sir; the time 1s eoming,
within the next half eentury, when this republie will dictate laws. not only in the arts and
sciences, hnt in pecuniary matters, to the
whole world. ‘he moneyed center of the
whole world is to be transterred from English
to American soil, if we are but trae to ourselves and use and develop the resonrees and
advantages bouotifully bestowed upon us by
nature. Mnugland must abandon her lines of
communication with her eastern possessions
aud become tributary to the lines we proposo
to constrnct between the Atlantic and Pacifie.
Her business inen and emigrants seeking China and Indix must cross opr contiuent and
py tribote to our enterprise and the genius of
obr institutions.” — Jraveler.
Tur Wie Buswess—The wine basiness of
tho State is rapidly on the increase. ‘The
grape erop, especiatly in the vicinity of Los
Angeles, is said to be better than it was last
year, yet so great is the demand for grapes for
the porpose of making wine, that they are
selling on the vines this season at $1 25 per
hundred pounds, while last year the masimpm
price was only 50 cents per hundred. So far
as this State is concerned, it is stated as a
fact that the native wines have pretty uear
driven all the cheap foreign wines ont of market. In addition, the demand for California
wines in the Hastern States is suid to be rapidly on the inerease. If it were not for the
high rates of money in this State, the produetion and export of onr wines would be trebled
in three years. As itis, the business shows a
gratifying inerease.
Tur Weatry or Triwity Cuuren—-Trinity
Chureh, New York is about to come once
more into possession of its landed property,
and its rent will enable the society to getnlong
quite comfortable. ‘he land originally covered
2,098 eity lots, of which, since 1848, 318 have
been given away, 1,059 have been sold, 691
are still owned by the ehnrch. Most ot these
lots are leased to other partics, bot the lease
will soon expire, and ‘Trinity will then have
about $20,000,000 worth of real estate. Jobn
Jacob Astor was shrewd enonghin 1776 to
obtain leases of 336 of these lots for ninetynine years at 75 cents a year for each lot. It
has been a very pleasnnt amusement lately for
Mr. William B. Astor to pay ‘over aunuall
$252 to Trinity and receive tor the nse of the
property abont $168,000. But Mr, Astor’s
leases will expire next year, and he will not be
able to renew the leases on such favorable
terms.—Hariford Posi.
