" 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. {From the Dairy Parr Press, Thursday, Augast 31] Duspar’s Seir-ADsustixo Srran-Paenino. 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. 135 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. Tue Frontier Scout is the title of a little newspaper just started at Fort Rice, Daeota Territory, by the officers of the garrison : Coptain E. G. Adams, editor. It is the only paper publisbed within thirteen huudred miles o that point. Tur operative carpenters and joinersin T.ondon are endeavoring to obtain an advance the preseut rate of gwages—38s, per weck, id. per hour.
