The MAlining and Scientific ress, 437 ESMERALDA. ‘ Rock of extraordinary ricltness was struck in the old Urul shalt, beluuging to the Del Monte nine, sometime last week. ‘The precious metal could be even all through it. ‘he Ural company had missed it when goit down. ‘The lead is said to bo about three und a bnlf feet thick, sbowing much gold. Betriox.—From tho Ist to the 3lst of May, according to the Jimes, Messrs. Krauss and Reese assayed ono luttlred aud thirty thousand five hundred nnd thirty-nine dollurs of bullion. ho same rato monthly would amonnt in twelve months to $1,566,468 00. ‘This it must be rememhered is only from one assay office. ‘The amount assayed Inst invnth is net a fair criterion by which to estimate the probahle sum of twelve months, becanse the yield of tho nines ig all the while on the inerea-e. We have many reasons for belioving that the mines will yield this year over two millious of dollars. Goin in Axcient Tines.—Whatever may have been the source whence tho ancicnts obtained their gold, thereis evideuce that this metal was admired and valued by them as inuch as itis at present, Many of the accounts given by enrly writers dnzzle us itto the supposition thot the stores of gold in those days were much larger than can he commanded nt present. ‘Thus Semiratnis is said to have crected atatues of Jupiter, Juno, and Rbea, forty fect in height, and mado of beaten gold. Drinking-vessels mnde of gold, and weighing twelve hundred talents, are also spoken of. The sumptuous displny of precious metals in the palaces of the great are frequently alluded to; but it has heen aptly observed that the quantity diffused among the bulk of the English population at the present would make a sum total far outbidding the golden wrenth of those earlier days, though less ohvious and glittering from being so much more diffused. Suggestions About Advertising, ADVERTISING AT THE Mixes.—Companies whose notices are required to he published in the county in which the miue is located, should be careful to have their advertisements forwarded iu season. No Assvssuents should he levied npon Friday . where the publication is to be made in the issue ofa paper puhlished on Saturdays only, at the mine or elsewhere. , Ox Recorn.—As a large proportion of our edition will he hound and preserved in volumes, those who patronize our colutnns will bave their advertisements preserved with a valuable record. For Servixo Persoya, Notices.—Sccretaries patronizing the Press can hnve their advertisements neatly printed npou slips at $1 per hundred. Avvertisine Brians for Secretaries who design publishing notices in the Press, sent to order or furished gratis, upon application to the office. Tne Earurr tne Better.i—Our advertisers are requestcd to send iu their favors as early as practicable. Report Your Exereiments.—How much that is learned by our intelligent and successful miners and . mill men, ig never communicated. Experiments are . constantly guing on, often with important results, . which would impoverish no one, hy being made puhlic, while they might save thousauds tu the State if they could only he made generally known. We are! qnito confident that there are many who possess valnable information, acquired from expericnce, who have no objection to makin the sane public, and who do indeed, communicate it to their immediate neighbors ; but no farther. Here is vnluahle information. Why not report your experiments through the Minixo anp Screntirrc Press, the accredited organ of tbe miners of this State? Tell us how you get certain results, that others also may profit. You bave no fears of competition. The material you are producing—gold, silver aud copper, are always in demand ; there is no danger that the market will be overstocked ; they will always sell. It matters not if you communicate in a burried way, so you only send us facts. We will put the same into readable sbape. Report your experiments. 5 This journal comcs to us thls week with a new head and enlarged to the tull slve of the Scicatific stmerican published In New York—slx teen pages. Those whe take an Interest In mining, Industry and art should not fall to read the prospectus of the Press, which may be found In our advertising columns, aud those who may deslro to see copies, lntendIng to subseribe, wlll have speclmens sent tree on apppiea ou by letter to tha olfice of 7 jon. 1 ‘orte, ’ The Mining and Scientific Press Patent Agency, OFFICE, 87, GOVERNMENT 1IOUSE, SAN FRANCISCO, Information About Obtaining Patents. The Patent Law Amendment Act, of Murch 4th 1861, and March 3d 1463, now In force, Introduces several hnpertint etuges in our Vit cut System. The neural practice of the (ntent Oflce, however, ln regurd tothe examination and Issie of Letters Patent for new lnyentlons, remalns nearly the sane heretofore, The amendmentol 4 March, 1463, provides, in eectlon 3, that every paler stialt be dated as of a duy not hier von 51x months atter the tine at whleh It was passed und allowed, und notlee thereof sentido the uppilennt or his ayent, And If the thal tee tor such patent be net paid whhln the sald six months, the pitent shall be witheld, and the Inventhn thereln deserlbed still become eye property as agsulnst the applicant therefor: Prerticd, That In ull cases aber patents linve been allowed previons tu the passage of this act, the gald six inonths shail be reckoned trom the date of such pasgsuye, The first question, theretoro, that presents Itself to the liventor, who desires tu procure a patent, Is; "Cun ]obtalia putent® A posltlye nuawer to This questlon 1s only to be had by Lae formal application Ir patent to tho Goverument,cmbracing a petition, speed? tention, model, duplicate, drawings, nil the payinent ot the preseribed otiletat fees. Aside trom these steps, all the Inventor can do ls, to sult his plans to persons experlenced In the business of obtuluing patents, und aolicit thelr opinion and advice. It the purtles eonsulted are honorable men, the Inveutor niay safely cenilde his ldeas to them, and they wlll Intorm hha whetber or not his inventiou ls probably patentable. Those who hnye made Inventions and desire to consult with us respucting the sine, are cordially Invited tu dose, We shail be happy to see them du person ut onr oflice, or to adylse them by mall, or through tho Mixing anb Sctentiric Press. tall cases they sees Cx: pee? trom us an honest opinion, For these consiutatlons, opin aud adviee, we make no charge. <A pen-anil-Ink sketeh, and deserip tlon of the Invention should be sent, together with weteni hoy return pustage. Writo pluin ; dv nut use peneil or pale Ink ; be brict. Remember thnt all business committed to our care, nnd all consultanons, are kept by usscerct, and strictly confldcntial, Preliminary Examinations. In somo cases It may be advisable as a nivasure of prudence to order n preliminary exmninatlou. This consists of a special search made at the U. 5. Patent Otllce, Was! throngh the dl oO our assechite In that ol) to uscertain whether among all the patents and inodels there stored, any Inventlon can be found which is simlTar lu character to that of the a letlon of this special search wo send a written report to Ihe party concerucd, with suitable ndvice. Onr charge for thls service, Including the report, la ten dollars. This scarch, though It Involves the expense just nained, wlli usually prove satisfactory. If jhe same devleo has been before patented, the time and expense of constructing models, preparing documents, ctc., will In most cases bo saved ; If theInvention has been Jn part patented, the applicant will be enablo tu mod ry his claiins and expectations accordingly. Many other obvious advantages attending the Prelimlnary Examination ; although the strictest scarch dues not always enable the applicant to know positlyely whether a patent can be had. Applicutlons Vor patents are often rejected hecanse the Examining otileer finds a description of the alleged inventlon In some foreleD publication ; or some other person fias bean previously Eclectic on an analagous device; or some other Invention lor a similar purpose, but partially rescnibles the upplicant’s In ite construetion ; ur the Govermncut makes nn unjnat or nncommon decision. Agalnst none of these contingencies does the PrellnInary Examination provide ; it will, however, generally Inforni the applicant whether an Improvement similar to his and ised ror the same purpose has ever been patented or not ln this comntry. Persons desirlng the Preliminary examination aro requested to remit the fee ($10), and furnish us with a sketeh and descrlptlon of the invention. Caveats, A Caveat Is a confidentlal communication mado to the Patent Office, and ls theretore filed within Its secret archives. The privllege sccurcd muder a caveat ls, that It entitles the caveator to recelve notlee, for a perlod of onc year, of ay application for a patent subsequently filed, and which Is adjndged to be novel, and is likely to Interfere with the Inventlon described In the caveat, and the caveator Is then required to complete hls application tor a patent within three nivnths trom Ihe date of sald nolice. Cuveat papers should be very carefully preparcd. Our fee for the service varies trom $10 to $20. The Government tce under the new law is reduced to ten dollurs; and this suin does not apply, as heretofore, as part of the lee on presenting an application tor a patent. Inventors will oftimes find lt very important to tako advantage of the caveat system—the expense under the law belng comparatively we only require a sketch enable us to prepare caveat paper, del being necessary. To and description of the invention ; no mot Expense of Applying for a Patent, Rejeotions, eto. Under the new law, the Government fee, on fillug an application for a patent, Is Iftcen dollars ; and It the patent ls allowed, twenty dollars additional js required. It reiected, the first tec of fitteen dol ars Is all that Is demanded. English, French, Austrian, Prnssian Spanish, and Inventors of every natlonality, inay now obtain pat ents m the United States upon the same terms as our own citizens The only discrimination nade is azalnst subjects of government that discriminate agalnst the Inhabitants of the United States. To the foregoing official lees must be added the Attorney's fees for preparing the varlous documents and drawlngs. Our charge for Preparing a casc, presenting it to the Government, and attending to all business connected with it, until a decision is given, ls trom $20 to $t0. It the patent ls granied no further agency cxpenscs ensucs.— If the application Is rejected we causo a thorouzh Investigation to be mado Into the reasons presented tu the Commissioner tor relusing the patent. 1n imaking this cxaminatlon, we havo excess to all tho drawings, models, books and specitications clted in reterence, and we report the result as early as possible to our client. For this service we make no eharge. If tho rejection proves to be an unjnst one—which sometimes happens—it can generally be reversed, and the patent obtalned by contesting the case. For this prosecution wo charge a fce proportionate to the extra labor involved, payable only on the issue of the patent; but onr demand will be reasonable and satisfactory to onr clients, and will bo arranged belorchand by special agreement. The system salar by ns worka well, gives general satlsfactlon and prescnts to all applicants, rich or poor, an cqual opportunity of having thelr patent cases prepared, conducted and prosecnted In the best nianner, by experlenced attorney's, npon the most moderate terms. Inventors who have rejected HERS ih aie elther by them selves, or tor them by other agents, and desire to ascertain their Prospects of auccess by further ctlorts, are Invited to avatl themselves of onr uneqnalled facilities In secnring favorable results. We have been successful in securing Lettcrs Patent In many eascs of sucb a Matter. Gur terms lor sucb cascs are very moderate. Models, Remittances, eto. The laws requires that the Inventor shall, In all cases, furnish a model, which must not exceed twelve Inches In any ot Its dimentions; it should be neatly made, ot hard wood or metal, or both, yarnished or palnted ; the name of the inventor should be engraved opr ied on It conspicuously. When the Invention couslsia of an Improvement on some known machine, a full working model of the whole will not be necessary, It should be sufficlently perfect, however, to show, wlih clearness, the nature and operation of the Inventlon. ‘As soon as the model Is ready, It should be carefully boxed and gbipnigd by express or otberwise, to our address, namely: Dewy & Co., Mining and Sclentific Press, rooms 56 and 67, Ooverument House, corner ot Sansome and Washington Streets, San Franelsco, Cal. Prepay expenses and send express recelpt to us by mail. Simultancously with the model, the Inventor should send first installment of the Government fee, fifteen dollars, The money may be forwarded elther by express with the model, or by mall — The satest way to remit Is by draft on San Francisco, payable to our order. Always send a jetter with the model, and algo the remittance stating the name and address of the sender. A full description shonld also be sent with the model, embodylng all the ideas ot the Inventor respeeting the Improvement, On thc recelpt of the model and Government fee, the case Is duly registered upon our hooks. and the application proceedcd with as 3 le. When the docu ts are ready we send them to the inventor by mall, for hig examination, slgnlure and atidavit, with a letter ol Instructlon, ete, Our tee for ate aring the easo la then due, and will be called for.
