Our senior editor has been taking notes in‘ Placer and Nevada counties this week. _OtR Mixing Summany this week presents anextensive variety. Bere, ten, 50 Ore tel Ud se QUARTZ MINING IN COLORADO, The Weekly Mining Journal, of Black Hawk, Colorado, under date of March 27th, has two articles upon the mining prospects of the Territory. It gives particulars regarding extensive, incipient or projected operations in various localities, and considers the prospects decidedly bright. 4t is, however, justly severe upon the system of exagveration that has been so unscrupulously practiced with respect to the present status and production of the mines. Upon this point it speaks as follows: “Tor our part, if the Territory shall .altogether produce five millions’ worth of bullion this year, we shall be vastly encouraged. It will be better than was done in hoth 1864 and 1865 together. Wedongtthink it au extravagant * * IJtis time that this extravagant talk about bundreds of mills in Colorado stamping out from twenty to lorty millions a year should cease. It only injures us. ‘There are not twenty mills in the ‘l'erritory that could, run successfully to-day, and a production this. year of five millions, although seemingly meager in the light of the gas heretofore emitted on the subject of our gold and silver yield, would be niost superlatively encouraging in the light of truth. Itis perhaps not too much to say, certainly not too much to hope, that it would be doubled next year.” It says further— “ Why try to couple the success of onr mines with the success of a single incthod of treating ores? And why, upon its inauguration, assume in cffect that we never produced any . gold hefore? And why, we might ask, in esti-. mating our production, is it necessary to always put it five or ten times as high as it is, so that the truth, which must appear sooner or later, shall be so cooling and disappointing ? If Colorado produces five millions of bullion this year. we shall he satisfied, and the country nay well be.” It also publishes the following— Figures.—It is earnestly to be hoped that one or more of tlie various separating processes now being tried in that Territory may prove thoroughly successful. The accounts from those of Mr. Lyou and Mr. Keith are very encouraging; hut capitulists and the mining public generally desire to know something inore than the mere fact that this process or that one turned ont a bar of bullion weighing say one hundred pounds. Vhey want to knuw the number of tons of rock from which that one hundred ponnd bar was extracted, und what it cost to extract it. These are the points by which they will measnre success or failure. Wedo not wish to doubt tbe success of Mr. Lyon’s process, for instance, hnt knowing how important it 18 to Colorado mining interest, we cannot help suggesting lo the press of thal Territory the propriety of ascerlaining and publishing the figures as lo the quantity, cost, time, etc. We are satisfied that Colorado will yet come out gloriously from her trials, and sueli an exhibit, if favorable, will hasten the time.—American Mining Index. Lyon isin New York just now; suppose you try your hand at ascertaining “ fignres as to qnantity, cost, time, ete.” Be sure you get the truth; if you lave to take any man’s word, verify it.if possible, and remember that whatever you report you are responsible for. ‘Mhen give us tbe immutable figures, and we will acknowledge the pertineucy of your numerous suggestions to the press of Celorado. There seems to be a little captiousness in these remarks of the Jowsnal, which is, perhaps, uncalled for. It is without doubt, in general, extremely dificult if not impossible to obtain full and reliable data as to cost, etc. Parties engaged in working difficult ores are apt to be reticent upon such matters, and as far as it affects their private interests, they have the right to be ro. Yoo much mystery ic such matters, however, always smacks of ignorance or hnmbug, aud proprietors of really valuable processes, as well as journalists, should always remember that nothing can he so convincing as facts like these; that general statements cannot supply their place, and that so far as tt can be done without prejudice to private inieresis, it is of the atmost importance to all concerned that . the truth in snch matters should he known and cirenluted as widely as possible. . Vhe Journal is very enthusiastic in its belief in the full and complete success of the Keith desulphurizing process. We shall, perhaps, be) more fally couviuced of this when it has been . . more exteusively tested, and niore detuiled re-. sults, have been published. As yet we have . serious doubts respecting it. There is‘a spirited cootest’ going on between! . the same journal and a certain John Wetherbee, . ol Boston, as to the merits of the Crosby and . Vhompson desulphurizing process, the Jounal being of opinion that this process is ‘‘a most consummate humbug.” Without enteriug into the merits of this dispute, which is largely personal, and iv which it may he difficult to learn the cxact truth, we will say that we are somewhat inclined to agree ‘with the Journal, as to its opinion of the process in qnestion. We have already published descriptions of this process and comments upon it. The talk put forth in connection with it, as to the existence of gold zm a volatile state in sulphurets, the ignoring of spccific gravity, ete., is too ahsurd to be seriously proposed to any one having a knowledge of the facts of chemistry aud of the simplest elements of mechanics. NEW INVENTIONS. Most of the followlng list of Patents, recently issucd to In yentors on the Pacific coast, were secured through the Mining anp Scientiric Press Patent Orrice Agency. Full copies of claims and spéeificatious can bo procured by application to us. g e) Axcmirecrurat Desions.—Samuel Kellett, of San Francisco, three pateuts for architectural center flowers. ‘These designs are beantifully wrought, after natural patterns of the California fruits and flowers, and are of an order of high adto-relievo, rarely if ever attained before. Iuproven Roorina Comrounn. — Gcorge Duncan, of San Francisco, claims the preparing of burlaps with a tarry and bituminous compound, and covering the same with bituminous compound, in the manner and for the purpose set forth. Coverixo ror Hypravtic Hosr.—Thomas McAuley, of San Francisco, and ML. Cheney, of Mlinoistown, California, claim the forming of a hose covering, by winding rope or cord spirally around a cylinder or former, and having for its support warps or strands of rope or cords passing around each spiral strand by means of a half twist, substantially and for the purpose herein specified and set forth. This invention relates to the covering of the common duck or canvas hose (used for hydraulic niining), with a net-work of cords, and consists in winding the cordage or rope, which constitutes the woof of the covering, spirally around a form of the desired size. Otber strands are placed at right angles with the spiral strand, arranged in pairs, und are made to cross each other witli a hulf twist, between each spiral of the woof. This invention is said to bave been very successful iu its practical tests. ~ Dounis-Acrine Pump.—Assaria Rewerick, of San Francisco, claims ‘the cylinders H and M, and pistons Hand N, wilh their valves, when arranged and operated substantially as described. ‘The above relates to an ingenious development for pumping, whereby the water is raised in a constant stream both by the upward as well as the downward stroke of the handle, hy the employment of one cylinder and piston-rod—tbe upward stroke lifting the same quantity of watcr as the downward stroke of the piston forces up. Pomr.—L. A. Gould, Santa Clara, California, claims connecting the rod, h, and hollow sleeve, /, respectively, of two buckets, 7, and /,¢. of a nump, to a comnion actuating lever handle or brake, on which the rod, 2, is hung, through the sector-shaped gears, s and J. and arm uw, all arranged and operating ae and for the purpose specified.” ; : PappLte Wueei.— Edward Jones, of San Francisco, claims 2 paddle-wheel provided with floats, convex ou their outer edges, and increasing in width towards the outer ends, arranged relatively to the wheel shaft and to the sails of the vessel, substantially as described and set forth. Orx CrusHer.— Zenas Wheeler, of Sau Francisco, (anti-dated Feb. 19th, 1866.) claims the combination with the stationary jaw g, of the movable jaw s, when the latter is cperated by the cam shalt, 0, and adjusted at its‘lower feud by means of the screw bolts, ¢, 2, which are hinged thereto, and adapted to produce the / summary very complete. motion described. Second, making the jaw dies in two or more sections or parts, substantially as hereiu described and for the purposes specified. Quartz Cavsner.—John Fleck, Santa Crnz, Cal., claims the two jaws A, A, provided with two upper inclined parts, @, a, aud lower vertical parts, 6,8, in connection with oscillating franie or walking beam B, and frames F, F, all arranged to operate in the manner substantially and for the purpose sct forth. Second, the combination of the jaws, A, A, oscillating frame, B, and wheels /, 7, for securing the upper ends of the jaws in the frame, as herein specified. *Gotp ann Sirver Wasniwa Apparatus. Joshua Hendy, of San Francisco, claims, first, the guide fingers, 'l', T, attached to distributur, G, working in slides V, ¥, or their equivalent. Second, the riffle bars, R, R, coated with mercury, for the purpose ae herein set forth. ‘Third, that the riffle barsR, R, guide fingers T, I, and slides U, U, in combinatiou with distributor, G, and pan, B, with convex bottom, and central outlets, E, 14, substantially as described, and for the uses and purposes as herembetore set forth. AcknowLepenrnt.— We have received from Mr. A. Sutro, who goes Hast by the next steamer,a copy of a magnificent lithograph, illustrative of the ridge in which the Comstock ledge is situated, and giving a plau of the proposed Sutro Tunnel. ° We have also received a copy of a beautifully printed pamphlet on the subject. of the Comstock, containing the report of T. Barnn Richthofen, Doctor of Philosophy, to the Board of Trustees-of the Sutro Tunnel, by whom be was-emplosed in his professioual capacity. Both of these works are deserving of a more extended notice than our time and space this week will allow. We hope to do them justice in our next issue. Tur“ Lirtce Grant” Quartz Mitt.— This machine, of which, it will be remembered we gave a description a few months ago, has met with favor in Ruby City, Idaho. H.A. Jones, Treasurer.of the Cosmos silver mining coimpany, No. 158 Broadway, New York, has received a letter from the financial agent of the company iu that place, announcing the fact that one was started into full operation there on the 15th of February, and that it was prononnced a perfect success. With a driver of 8-horse power, it is reported to have pulverized one thousand pounds of ore per hour, to a sufficient degrce of finencss to pass through a sieve containiug 5,000 meshes to the square inch. This is said to he only one-half of its capacity if accompanied by a crusher,as delineated in the cut accompanying the notice in the Press, to which we have referred. R. H. Vance, 25 Nassau street, corner Cedar street, New York, receives orders there for the machine, and 8. B. Pike, inventor, at the Miner’s Foundry. for the same in San Francisco. Tue “ AwgRICAN JOURNAL or Muninc.”—~ This is the title of a new weekly journal of sixteen pages, published in New York, the first two copies of which we have just received. Its salutatory uddress is briefand modest; making-no special promises, except that politics, being entirely “incompatible with the spirit and scope of such a paper,” will be utterly ignored. ‘The typographical execution of the paper is remarkably neat, and its mining The suhject of petroleum very properly receives a large share of its attention; and oil companies, as well as gold and silver mining companies, are tabulated iu a very convenient form. ‘ A ris#, four inches long, and without eyes, . Was pumped out of an oil well at-Pithole, Pa., ashort tine ago. ‘The well was six hundred and sixteen feet deep. The fish was put iutewater, but lived only a few hours. In addition to other machinery being erected in the Rawhide Ranch mill, ‘Tuolumne county, our special: correspondent should have mentioned in his communication last week, four of ITeudy’s Patent Improved Concentrators.
