The Mining and Scientific Press, 233 lect to some extent, or a kind of trading jargon which serves for international communications. ‘hey are not friendly to each other, hut do not fight much. ‘They are all dying ont, of asthina and lung complaints, eaused by a *' forty rod” tobacco which they get from the Russians, and the fumes of whichnore drawn incessantly into the lungs. It does not appear that the interior or true American Indians havo any relationship whatever to tribes in Asia. The coast and interior Indians luild houses alike, the latter having borrowed their ideus from the coast, if they haveany honscs at all. Winter houscs are half underground, and covered with carth, having ahole in the roof. Fire is made abont twicea day. They get into their houses by an underground passage ten or fifteen feet long, on their lands and knees, the exit being vertieal like a gronnil-hog’s hole, and franied over, to keep out the snow. Communistic principles are in vogue as to dwellings, and general property. Both the coast and interior Indians aro honest, and do not stezl nor murder, excopt where they have heen supplicd with whisky by the traders. ee te oe Contributions for cur Cabinet. rthls heading we elinll cantinue to mention and iletbe, uceurdiag tu merit, ech spechuens of ures, mluerals, fossiis, curlostites, as muy be presented, oF an Jed tous by matlor Tess, prepald.

Haven, of Gold Lake, Sierra County, has sent us specimens Nos. 250 to 270 inclusive. No. 250—Opal jasper; silica, containing alargeamount of water, and several per cent. of iron; hardness hetween that of apatite and feldspar; being float or surface pieces from the grnvel mines, and found in the vicinity of mineral charcoal. No. 251—The same, found near the surface, granulated, and with less iron, which is partly in the form of greenish protoxide, and partly of the yellowish tinge whicb iron assumes in the cold borax glass. No. 252—Opal, white and yellow varieties, the Intter having tho peculiar transInceney of chaleedony and the resinous glance of the pitchstone. On one surface there is a whitc, soft mineral resembling chalk, but containing a great deal of alumina, cleaving strongly to the tongue, and when touched to water drawing it in eagerly with a rushing noise, without becoming plastic. No, 253—Variety approaching to wood opal, which would commonly be called a petrifaction, as it shows.a grained structnre. All of the rbove specimens are silicious concretions, like those so common in the chalks of Iingland; occurriug, as Mr. Haven says, in nests like hills of potatoes, but eracking and becoming coarse granular when exposed to the air. The country is described as a “ hurnt-lime, reddish sandy soil,” and appears devoid of carbonates. No, 254—Casing of the concretions; hardness like the preceding; in composition probably about the same us skapolitb ; in appearance resembling porccllanite. No. 255—Genuine jasper, with beautiful bluish manganese dendrites, No. 256—Cbalcedony. No. 257—Trachite. No. 258—Hornhlendic porphyry, witb epidotic ground mass. No. 259—Lime garnet, or grossular, charReteristically erystallized. No. 260—Iron garnet, or almandine, known in jewelry as the carhnnele. Prohably some of these would he paid for by the jewelers, as they possess the deep translueent red chnracteristics of the precious garnet. No. 261——Gold quartz from Gold Lake.

No. 265—Hornblende rock, with coating of lime, probably from decomposition. No. 266—Hydrated oxide of iron.

Of nothing are our millwen more thoroughly convinced in these times thau that quicksilver will not acconiplish everything for them. Cirenmstances, aud combinations of ores containing different ingredients, occur daily where the mercury refnses to go aftcr the precious metal; there is an aversion, instead of an aftinity. Millmen are even beginning to bo nware that they must be more than ‘‘millmen.” Beautifully-working iron staup mills and quicksilver tuhs will fill the bill only partially, in silver reduction cspecinlly—a proposition demanding now no proof. Heuce chlorination, and sodium amalgam, and smelting, are receiving attention, and are heing brought into practice ; frequeutly to the henefit of enthusiastic experimenters, but more in the acquirement of a knowledge of practica] metallurgical chemistry and of wisdom, than otherwise; which, after all, may be worth more as an attainment in life than the gold and silver which we seck for so lahoriously instead, and do not always find. Thus thousonds of experiments aro made that result in the general good, though too frequently to the loss of ‘‘the company.” Withont touching upon the question of how this dear experience can be best got ronnd, or obtained most economically, we will mention a thing or two about two new allicd metallurgical processes whicb have some interest in connection witb gold and silver extraction, and which seem to hang in suspense—prohably frozen fast in the rejected crucihles of more than one experimenter who does not fully comprebend the nature of his failure. We allude to the zine process of Mr. d’Heureuse, of this city, and the lead process of Mr. Fuller, of Chicago, both of whicb are patented, yet, so far as heard from, lying idle on the patentees’ bands. The powerful affinity of zinc and lead for gold and silver are ancient facts, that beeame known to smelters bundreds of years ago, for it was by smelting alone that all those metals were formerly extracted; and they occur together, more or less, all over the world. Full advantage is taken of the relative affinities of these metals in all the great smelting works of England and Germany, as well as out of these countries, . where such establishments are little more than copies in the main, The Pattinson process, which is based on the earlier crystallization and different specific gravity of poor silver lerd from rich silver lead, so that the former may be skimmed off, had for its result the profitable remuneration of whole mining districts that had lain unworked for scores of years hecanse the ores could not he made to pay—a brilliant example of the immeuse value and power of a little unthought-of principle. The Parkes process makes use of a similar characteristic in the alloy of zine with silver and lead. The resulting alloys are afterwards separated by cupellation ond liquation, or sublimation. The new processes of d’Heureuse and Faller differ from nll previous applications of tbe affinities of zinc and lend, in proposing to melt nothing but the zine and lead respectively, requiring only a moderate beat, while the ores are left in their original condition, and are simply passed through the bath of melted metal by mechanical means. Were the heat increased to the} smelting point of the orcs, silientes would . he formed, of a lighter specific gravity, and the process would not differ from ordinary . smelting; but for that purpose proper ! furnaces and expensive blasts would be necessary. The advantages claimed by both tho patentees are the cheapness of the simple pot or kettle required, and the per. fect taking out, by the zine or lead, of all the gold and silver in the ores that can be . shown to exist by means of fire assay. So . far as these claims ara concerned, they are . probably not very for wrong, But there are theoretical difficulties, if not practical ones, thathaveto be encountered, and which will appear obvious to the ietallurgist. The sulphur introduced with the sulphurets in the lead proccss must necessarily comhino with the metallic lead, and make a matt of sulphide of lea, which, being of a ligbter specific gravity than the lead itself, will float in tho form of a stratum on top. We shall have all the phenomena of cupola smelting, excepting only the third strntum, consisting of silicates. Chemically expressed, the pyrites, PceS’,+Ph, will assume the forms of FeS+Phs. In the zine process, the result will be the same, with the additional aggravation of a greater liability to oxidation of the zine. Whether theoxidesand sulphides so formed would be measurably freo from silver, or what amount of redncing, and matt desulphurizing, would havo to be done in the daily operation of a process of working any given ore, are questions of economy, to be solved only by practical experiment and by the richness ond refractory charaeter of the ore by ordinary processes. Possibly the addition of iron might be made use of econimically to precipitate the lead from its combination with sulphur in tbe matt. We have watched the course of so many distressed, emaciated and forlorn dyspetics, of wornout and prostrnted females, who have taken a new lease of life, and gradually received vigor, strength, health and the power of social pleasure from the effects of Puantation Bitters, that we are not surprised at the testimonials daily received.
