In the diataiico, a bulldi'ng like a large storehouse, evidently noi made by India" Th0 tbi" ,s nithc' rirh nor rare; the only wonder is, how it Rot there. For many hours before coming tn sight of this building, no sign of humno life Is visible, unlcce, perchance, the Jojiul passengers catch the dent of a dug-out canoe, with a blanket for a naXl, In which an Indian fisherman sits solitary and motionless, hs thouch he, too, were one of the Inanimate features of the scene. On drawing near this most unexpected atructuro, the curi osity of the travellers is changed into wild -wonder. It Is a storehouse with all the modern Improvements, and over the door Is a well painted sign, bearing the words "Easpberry Jam." II Ihe present writer, when he first beheld this sien. had rend thereon "opera glasses tor hire," or "kid gloves cleaucd by a new and improved method," he could not nave been more sur prised or more puzzled. The explanation, how ever, was very simple. Many years ago, ic seeus, a Yankee visiting that rep ion discovered inou satide upon thousands ol acres of raspberry but-hea banging full of fruit, and all goini; to -waste. IIo also observed that Indian girh and squaws in cousiderable numbers lived near by. Patting this and thai tieeiher, he conceived tue ideaol novel speculation. In the summer fol lowing ho returned to the pluce with a copper kettle, many barrels ot sugar, and plenty of large stone Jars. For one cent a pail be bid as many raopbeiries picked as he could use; and be kept boiling and jarring until he bad tilled all his vessels with jam, when he put them on b jard a sloop, took them down to Detroit, and sold them, the article being approved, and the specu lation being profitable, he returned every year to the raspberry country, and the business grew to an extent which warranted the erection of this large and well-appointed building. In the Western country the raspberry jam made in the region of Luke Huron has been tor twenty years an established article of trade. We had the curiosity once to taste tarts made of it, and can testily that It was as bad as heart could wish. It appeared to be a soppy mixture of melted brown sugar and small seeds. But that is neither here nor there. The oddity Of oar adveoture was in discovering such an establishment in such a place. Since that time we have olten had similar surprises, especially in New England, where curious industries have established themselves In the most out of-the-waj nooks. In a hamlet of thre or our houses and a church we see such einns as "Melodeon Manufactory." At a town in Northern Vermont we hod lour hundred men busy the year round in making those great Fairbanks' Scales which can weigh an apple or a tram of cars. There is nothing in St. Johnbbury which marks it out as the town in the universe fittest to produce huge scales for mankind. The business exists there because, forty years ago, there were throe excel lent heads in the place upon the shoulders of three brothers, who put those heads together and learned he to reako and how to sell scales. All over New ingiand, ind ustn't! ha rooted them selves which appear to have no coagruii? vlih. the places in which they are found. We heard the i other day of a village in which are made every year three bushels ot gold ring-. We ourselves passed, some time ago, in a remarkably plain New England town, a manufactory of tine dia mond jewelry. . In another town Providence there are seventy-two manufactories of common Jewelry. Now what is there in the character or in the situation of thts city of Roger Wil liams that should have invited thither so many makers ot cheap trinkets? It is a solid town, that makes little show of its great wealth, and nr.rxt aya aam thon 4 It a o vara cm r tim hnt rf VVU l ItlUR KOI V t U but- . V U U W S ft people capable of wearing tawdry ornaments. Nevertheless, along with, machine shops of Titanic power, and cotton mills of vast extent, wc find theft seventy-two manufactories of Jewelry. The reason is, that about the year .795 one man, named Dodge, prospered in Providence by making such jewelry as the simple people of those simple old times would buy ot the passing peddler. His prosperity lured otheisinto the business, until it bus grown to its present proportions, and supplies half the country with the glittering trash which we all despise upon others and love upon ourselves. But there is something at Providence lews to be expected even than seventy-two manufacto ries ol Jewelry; it is the largest manufactory of solid silverware in the world I In a city so ele gant and refined as Providence, where wealth is so real and stable, we should naturally expect to find on the sideboards i lenty of silver plate; but we were unprepared to discover there three or four hundred sJtUtul men making silverware for the rest ot mankind, and all in oue establish ment that of the Gorham Manufacturing f!nm. yiany. This is not only the largest concern of the kind in existence, Dut it la the most com plete. Every operation of the business, from the melting of the coin out of which the ware is made, to the making of the packing-boxes in which it is conveyed to New York, takes place in this one congregation of buildings. Nor do we hesitate to say, alter an attentive examina tion of the products Vf European taste, that the' articles bearing the stamp of this American house are not equalled by those imoorted. There is a fine simplicity and boldness of outline about tne lorms produced nere, together with an abunce of. useless and pointless ornament, which render them at once more pleasing aud more usef ul than any others we have senn. It was while going over this interesting esta blishment that the raspberry jam incident re curred to us. Thu thing, however, is both rich and rare; and jet the wonder remains how it got there. It got there beeaue, forty years ego, an . honest man began there (t business Which has grown steadily to this day. It got there just as all the rooled business of New Eng land got where we find them now. In the brief history of this one enterprise wo may read the history of the industry ot New England. Not the less, however, ought the detailed history to be written; for it would be a book full of everv kind ofiuterest and instruction. M,hl wa?

It is not surprising. thbiZP? Mr. btewart Is now the monarch of the dry ' &tft trade in the world; and we fully believe thai u history of all lasting success would disclo a similar root of honesty. In all the bust which have to do wltn the precious metals and precious stones, honesty is the prime necessity; because in' them, though it is the easiest thin in the world to cheat, the cheat is always capable ol being detected and proved. A great silver borne holds itself bound to take back an article of plate made forty ye trs atro, if it Is discovered that the metal is not equal in parity to the standard of the silver coin of the country in which it was made. The entire and per'ect littoral honesty, therefore, of Jabea Gorham, was the direct cause of the prosperity of the house which he founded. Ue Is now a serene and healthy man of eighty-two, long giro ittired Irow business. He walks about the fcsnulactery, mildly wondering at the extent to which its uceratious have extended. "It is liowa putt me h says with smile: "I know JwUJiif but all th, T1TE DAIL1 EVENING TELEGKAPU PHILADELPHIA, THUPSDAY, In ihe year 1W5 this vrnrrnblo old man wis an sppreuttce to tliHt Mr. Dodce w ho b'an in Providence the manufacture of ear-rniB", breast pine, and riiiR Hie only articles made by the Province Jwrl.ers lor many yours. In due time Jabez (iorbum et up lor himself, and he added to the list ot articles tne important it"m ol watrh-ebaius of n peculiar pattern, long known In N?w Kneland as the "Gorham chain." The old gentleman gives an amusing account of Ihe simple manner in which business was done tn those days. When he had manufactured a tmnkfulof jeclrv he would log away with it to HoPton, where, after depositina; the trunk In his room, he would go round to all the jewellers in the city to inform t hem of his arrival, and to say that his jewelry would be ready in his roim lor inspection on the following mornlnsr at 10 o clock.and not before. Detore the appointed hour every jeweller in tne town would oe at h s door; but as it was a point of honor to give them all an equal chance, no one was' ad mitted till the clock ptruck, when all pushed In In a body. The iewelry -was spread out cn the bed, oiound which all the jewellers ot Uostcn, In 18?0, could matlier without crowd ing. Kaoh man beean by placing his hat in some convenient place, and it was in his hat ihat he deposited the articles selected by him for purchase. When the whole stock had buen transferied from the bed to the several hats, Mr. Gorbam took a list of the contents of each; whereupon the jewellers packed their purchases and carried them home. In the course of the oay the bills were made out, and the next morn ing Jlr. (iorhnm went his rounds and collected the money. Tlie business beinir thus happily couclnded, he returned to Providence, to work uninterruptedly tor another six months. In this manner Jabez (Jorbnra conducted business for sixteen years be: ore he ever thought of attempt ing silverware. Such was his reputation lor scrupulous honesty that, for many years before he lelt the biu-iuess. none of his customers ever subjected his work to any test whatever, not even to that of a pair ot scales. It is his boat that during the whole of his business career of more than hall a century he, never sold an arti cle of a lower ttandard of purity than the one establtthed by law or by the nature of the pre CiOUs metals. About the year 1825 some Boston people dis covered that a tolerable silver spoon could be made much thinner than the custom ot the trade had previously permitted, and that these thin spoons could be sold by peddlers very ad vantageously. The consequence of this disco very was that silver spoons became an article of manufacture in Boston, whence peddlers con veyed them to the remotest nooks of New Eng land. Oue day, in 1830, the question occurred to Jabez Gorbam, why not make spoons in Providence, and sell them to the peddlers who buy our Iewelry 1 The next time he took his trunk of trinkets to Boston he looked about him for a man who knew something of the art of spoon-uiakiDg. One such he found, a young man just "out ol his time," whom he took back with him to Providence, where he established him in an odd corner of his jewelry shoo. In this way, thirty-seven years ago, the business began which has grown to be the largest and most complete manufactory of silver ware in the world. - For the first ten years he made nothing but spoons, thimbles, and silver eombs, with au occasional napkin-ring, if any oue in Provi dence was bold enough to order one. Busi nesses grew very slowly ia those days. It was thought a grand success when Jabez Gorham, after neaily twenty years' exertion, had fifteen men employed in making spoons, forks, thim bles, napkin-rings, children's mugs, and such small ware. Nor would Mr. Gorham, of his own motion, have ever carried the business much further; certainly not to the point of pro ducing articles that approach the rank of works of art. We have heard the old gentleman say that he often stood at a store-window in Boston, wonderirg by what process certain operations were periormed in silver, the results of whieh he saw before him in the form of pitchers and teapots. . But in due course ot time Mr. John Gorham, the present bead of the bouse, eldest son of the lounder, came upon the scene an aspiring, in genious young man, wnose nature it was to excel in anything in wmcn ne migm caance iq engage. The silversmith's art was then so little known in the United States that neither work men cor information could be obtained here in its higher branches. Mr. John Gorham crossed the ocean soon after coming of age, and exam ined every leading silver establishment in Kurope. He was lreely admitted everywhere, as no one in the business had ever thought of America as a possible competitor; still less did any one see in tins quiet xanitee youtn tne per son who was to annihilate the American demand for European silverware, and produce articles which famous European nouses would servilely copy. - From the time of Mr. John Gorham's re turn dates tne eminence oi tne present company and of the production of the costlier kinds of silverware, on a great scale, in the United 6tate, From first to last the aompany have in duced sixty-three accomplished workmen to come from Europe and settle in Providence, some of whom might not unjustly be enrolled in the list of artists. , The war gave an amazing development to this business, as it did to all others ministering to pleasure of the sense of beauty. When the war began, in 18C1, the Gorham Company em ployed about one hundred and fifty men; and in 1864 this number had increased to four hundred, all engaged in making articles of solid silver. Even with this great force the company were sometimes unable to supply the demand for their beautiful products. Uu Christmas moro lug, 1864, there was left in the store in Maiden lane, New York, but Beven dollars worth of ware, out of an average stock of one hundred thousand dollars' worth. Perhaps we ought not to be surprised at this. Consider our silver weddings. It is not unusual for several thou sands of dollars' worth of silver to be presented on these occasions in one iastance.sixteen thou sand dollars worth was given, And what lady can be married, nowadays, without hav ing a few pounds of silver given to herf For Christmas presents, of course, silverware is always among the objects dangerous to the sanity of those who go forth, just before the holidays, with a limited purse and unlimited desires. What particularly surprises the visitor to the Gorham Works, at Providence, is to see labor saving machinery the pouderous steam ham mer, the stamping aud rolling apparatus em ployed in silver work, instead of the baser metals to which they are usually applied. Nothing is done by hand which cau be done by machinery; so that the three hundred men usually employed in solid ware are in reality doing the work of a thousand. The first opera tion is to buy silver coin lu Wall street. In a bag of dollars there are always some bad pieces; and as the Company embark their reputation in every silver vessel that leaves tho factory, and lire always respomiblo for its purity, each dollar is wrenched asun Jer and its goodness positively ascertained before it is thrown into the crucible. The subsequent operations, by which these spoiled dollars are converted into objects of brilliant and enduring beauty, can better bo imagined than described. New forms of beauty are the constant study of the artist in silver. One large apartment in the Gorham establishment the artists' room is a kind of maeaziue or storehouse of beautiful forms, which have been gathered in the course ol years by Mr. George Wilkinson, the member of Ihe Company who has charge of tho design ing, and who is himself a designerof sing ul tr ttiste, fertility, end judgment. Here are de posited copien or drawings of all the former inouucts or tne establishment. Hero is a large costly library of illustrated works in every geUril"l'ut of 81 1 ftnd science.

A silver salver of largo size costs a thousand dol lars. A cunipleto dinner set tor a party ol twenty-four cosis $12,000. The price ol a nice tra set chu easily run into $ 3000. We noticed one small va.o, six or eight inches high, exqui sitely chase a on two sides, which Mr. WiUiii sou assured ns cost the Company about $700 to produce. There are, as jet, but two or three persons in all America who would be likely to become purchasers of the articles in silver which rauk In Eurore ns works of art, aud which are strictly entitled to that distinction. The wonder is who buys tho massive utilities that are stacked awny In such profusion in Maiden lime. The Gorham Company have always In course of manufacture snout three tonso: silver, and. usually have ft ton 01 finished work lor sale. An Important branch of the busiiie8 is one recently introduced the manufacture of a very superior kind of plated-were, intended to com bine ibe strength of baser metal with the beauty of silver. The manufacture ot such ware has attained a greut development in Eng land ot late year, owing chietly to the appli cation ol the mjsterious power ol electricity lo the laving on of the s.lver. We must discourse a little upon this admlrablo application ol sci ence to the arts. "Hamlet" amused his friend "Horatio" by tracing the noble dust ot Alexander till he fouud it stopping a bunghole. If we trace the course ol discovery that resulted in this beautiful art, we shall buvo to reverse "Hamlet's" order; we must begin with the homely object and end with magnificent ones. Electroplating, electrotyping, the elecitic telegraph, and many .other aits and wonders, all go back to that dish o' frogs which the amiable and lond Professor Galvanl was preparing for his sick wile's dinner one dav. about the year 17H7. It was a curious reflection, when we were illuminating our houses to cele brate the laying of the first Atlantic cable, that this bewildering and unique triumph ot man ovi r nature had no more illustrious origin thau the lets of an Italian frog. We are aware that the honor has been claimed for a Neapolitan mouse. There t a story in the books of a mouse in Naples that had the impudence, in 1786, lo bite the leg of a professor ot medicine, and was caught in the act by the Pioi'essor himself, who punished his audacity by dissecting him. While ooing so, he observed that whe,n he touched a nerve of the creature with his knito its limbs were slightly convulsed. The Pro fessor, struck witn the circumstance, was puzzled by it, mentioned it, and it was recorded; but as nothing iurther came of ft, no connection Can be established between that mouse and the splendors of silver-plated ware and the wonders of the telegraph. The claims of Professor Galvani's frog rest upon a sure foun dation of tact. Blgnora Galvanl so rune one version of the 6tory lay sick upon a couch in a room in which there was that chaos of domestic utensils and philosophical apparatus that may still be observed sometimes in the abodes of men addicted to science. The Professor himself had prepared the Irogs for the stewpan, and lelt them upon a table near the conductor of. an electrical machine. A student, while experi menting with the machine, chanced to touch with a steel instrument one of the frogs at the intersection of the legs. The sick ladv observed that as olten as he did so the legs were convulsed, or, as we now say, galvanized. Upon her hus band's return to the room she mentioned this strange thing to him, and he immediately re peated tho experiment. From 1T60 to 1790, as the reader is probably aware, all the scientific world was on the qui cite with regard to electricity. The most bril liant reputations of that century had been wou by electiic discoveries. Franklin wa3 still alive, to reward with his benignant approval those who 6hould contribute anything valuable, alter bis cwn immense additions, toman's know ledge of this alluring and battling element. It was, therelore, as much the spirit of the time as the penias ol the man that made Galvanl seize this new fact with eagerness, and investi gate it witn untiring enthusiasm, it was a sad dSJ for the frogs of the Pope's dominion, wheu Mguora Galvanl observed those two naked legs fly apart and crook themselves with so much auimation. There was slaughter in the swamps of Bologna for many a month thereafter. For mankind, however, it was a day to be held la everlasting lemembrance, since it was then that was taken the first step towards the galvanic battery 1 As fortune favors the brave, so accident aids the ingenious. Alter Professor Galvanl bad touched the muscles and nerves of many frogs with the spark drawn from the electrical machine, another accident occurred which led directly to the discovery of the galvanic battery. Having skinned a frog, he chanced to hang it by a copper hook upon an iron nail; and thus, without knowing ft, he brought together the elements of a battery two metals and a wet frog. His object in hanging up the frog was to see if the electricity of the atmosphere would f roduce any efiects, however slight, similar to hose produced when the spark ot the machine was applied to the creature. It did not. After watching bis frog awhile, the Professor was proceeding to take it down, and while in the act of doing so the legs were con vulsed. Struck with this occurrence, he re placed the frog, took it down again, pat it back, took it down, until he discovered that, as oiten as' the damp frog (still hanging upon its iron hook) touched the iron naU, the con traction of the muscles took place, as if the frog had been touched by a conductor con nected with an electrical machine. This experi ment was repeated hundreds of times, and varied in as many ways a9 mortal ingenuity could devise. Galvanl at length .settled down upon the method following: He wrapped the nerves taken from the loins of a frog in a leaf of tin, and placed the legs of the frog upon a plate of copper; then, as olten as the leaf of tin was brought in contact with the plate of copper, the legs of the frog were convulsed. People regard Charles Lamb's story of tho discovery of roast pig as a most extravagant and impossible fiction; but, really, Professor Galvani comported himself very much in the manner of that great discoverer. It was no more necessary to employ the frog's nerves in the production of the electricity, than it was necessary to burn down a house in roabting pig for dinner. The poor frog contributed nothing to it but his dampness as every boy in a tele graph office now perceives.' He was merely the wet in the small galvanic battery. Professor Galvani, however, exulting in his discovery, leaped to tho conclusion that this electricity was not the same as that produced by friction. He thought he had discovered the long-sought something b,y which the muscles move obedient to the will. "All creatures," he wrote, "have an electricity inherent in their economy, which resides specially in the nerves, and is by the nerves communicated to the whole body. It is secreted by the brain. The interior substance of the nerves is endowed with a conducting power tor this electricity, and facilitates its movement and its passage from one part of the nervous system to another; while the oily coat ing of these organs hirnrs the dissipation of the fluid, and permits lis accumulation." He also thought that tho muscles were the Leydeu iaj;s ot theuuimal system, in which tho elec tricity generated by the brain aud conducted by the nerves was hoarded up for use. When a man was tired, he had merely used his elec trlcity too fast; when he was iresb, his Leydeu jtir were all full. The publication of these experiments in 1791. accompanied by Galvani's theory of amoral electricity, produced a sensatiou in Bcioutitio circles only inferior to that caused bv Frank lin's demonstration of the identity of lightning with electricity, thirty years before. The mur der of innocent frogs extended from tho marshes of Bologna to' the swamps of ail Chris leniiom. "Wherever," says a writer of the time, "frogs were to be found and two dilleront metals could be procured, every one was anxious to see tho mangled limbs of frogs brought to life in this wonderlul way." Or. as Lamb says, in the dissertation upon Roast Pig: "iho thing took wing, and now there Vas nothing to be seen but fire in every direction." At ttrt the facts and the theory of Galvanl were equally accepted; aud a grateful woild Insisted uion styling the new suieuee, us it was deemed, "Galvanism." Thus a word was added to all the anguei, which has bceu found useful In it literal lensc, and forcible in ns figurative. Whatever we may think of Galvani's philosophv, wc ennnot deny tuat he immortalize I his name He died a few jcars sftet, fully satlitied wi h Lis theory, but having no suspicion of the msny, the peculiar, Ihe marvellous results thai were to flow fiom the Chance discovery of the fact that a moist fiog placed boiween twodii leient metals was a kind of eleetricul machine. Among the Iia tans who caught at Galvani's discovoiy, the most Fkilful and learned wa Pro leo VoltH, of Conio, who had been an ardent electrician from his youth. Many of our read ers have seen this year the colossal statue of that gient man, which adorns his nalive city on the southern shore of the luke. Tho statue was wonhily decreed, because the man who contri butes ever so little to a grand discovery in science provided that little is essential to it ranks among the greatest benefactors of his species. And what did the admirable Volt-i dis cover? Iteduciiig the labors of his long liie to their simplest expression, we should say that his just claim to immortality consists in this be lound out that the trog hai nothing to do with the production of electricity in Galvani'o experiment, but that a wet card or rag would do as well. This discovery was tho central fact of his scientific career of sixty-four years. It took all of his lamiliar knowledge of electricity, acquired invtwenty-seven years of entire devo tion to the study, to enable him to Interpret Galvani's apparatus so far as to get rid of the frog; and he spent the remaining thirty-seven years of his existence in varyiug the experiment thus freed from that "demd damp, moiut, un pleasant body." It was a severe ailliction to the followers of Galvanl and to the Uulversity ot Bologua to have their darling theory of the ner vcus electricity so rudely yet so unausweraoly reluted. I do not need jour frog I" exclaimed the too Impetuous Volla. "Give me two metals and a moist rag, and I will produce your animal electricity. Your Irog is nothing but a moist conductor, and in this respect is not as good as a net rag." This was a decisive fact, and it silenced all but a lew of tho disciples ot tc dead Galvani. Volta was led to discard the frog by observing that no electric tesulis followed when the two plates were ot the same metal. Suspecting from th.s that the frog was merely a conductor (In stead of the generator) of the electric fluid, he tried the experiment with a wet card placed between two pairs of plates, and thus discovered that the secret lay in the metals bciog hetero geneous. But it cost thousands of experiments to reach this result, and ten years of ceaseless thought and exertion to arrive at the invention of the "pile," which merely consists of many pairs of heterogeneous plates, each separated by a moist substance. The weight of so much metal squeezed the wet cloth dry, and this led to vari ous contrivances for keeping it wet, resulting at last in the invention ot tho familiar "trough battery," now employed in all telegraph olficca and manufactories ot electro anything. Instead of Galvani's Irog, or Volta's wet rag, the con ductor is a solution of sulphuric acid, which Volta himself suggested and employed. The negative electricity is conveyed to the earth by a wire, and the positive is conducted from pair to pair, increasing as it goes, until, if the bat tery is large enough, it may have the force to send a message round the world. And the cur rent is continuous. The galvanic battery is an electrical machine that goes without turning a handle. By the galvanic battery electricity 1b made subservient to man. Among other things, it sends his messages, faces his type with copper, silvers his coffee-pot, and coats the inside of his baby's silver mug with shining gold. The old methods of covering metals with a plating of silver were so difficult and laborious, that durable ware could never have been pro duced by them except at an expense which would have defeated the object. In those slow and costly ways plated articles were made as late as the year 1840; and thus they might be made at the present moment, if Signora Galvani had been looking the other way when the stu dent touched the frog with the knife. More than fifty years elapsed before the chance dis covery was made available id the art we are. considering. For many years the discoveries ot Galvanl and Volta did not appear to add much to the resources of man, though they excited his "special wonder." Eldeily readers can per haps remember the appalling accounts that used to be published, forty vears aeoormore, of the galvanizing of criminals after execu tion. In 1811, at Glasgow, a noted chemist tried the effect of a voltaic "pile" of two hundred and seventy pairs of plates npon the body of a murderer. As the various parts of the nervous system were sub jected to the current, the most startling results followed. The whole body shuddered as with cold; one of the legs nearly kicked an attendant over; the others heaved, and the lungs inhaled and exhaled. At one time, when all the power of the instrument was exerted, we are told that "every muscle of the countenance was simulta neously thrown into feartnl action. Kage, horror, despair, and anguish, and ghastly smiles united their hideous expression on the mur derer's lace, surpassing tar the wildest repre sentations of a Fusseli or a Kean. At this period several of the spectators were obliged to leave the room from terror or sickness, and one gen tleman fainted." The bodies of horses, oxen, and sheep were galvanized, with results the most surprising. Five men were unable to hold the leg ot a horse subjected to the action of a powerlul battery. So far as we know, nothing of much import ance has yet been inferred from such experi ments as these. Davy and Faraday, however, and their pupils, did not confine their attention to these barren wonders. Sir Humphrey Davy took the ''pile" as invented by Volta, in 1800, and founded by its assistance what may be styled a new science, and developed i to the point where it became available for the arts and utili ties of man. The simple and eu y process by which silver and gold are decomposed, and then deposited upon metallic surfaces, is only one of many ways in which the galvanic battery minis ters to our convenience and pleasure. If the reader will step into a manufactory of plated ware, he will see, in the plating room, a trough containing a liquid resembling tea as it comes from the teapot. Avoiding scientific terms, we may say that this liquid is a solution of silver, and contains about four ounces of silver to a gallon of w ater. Tnere are also thin plates of silver hanging along the sides of the trough into the liquid. The galvanic battery which Is to set this apparatus in motion is in a closet near by. The vessels to be plated, after being thoroughly cleaned and exactly weighed, are suspended lu the liquid by a wire running along the top of the trough. When all is ready, the current ot elec tricity generated by the small battery in the closet 1b made to pass through the trough, and along all the metallic surlaces therein con tained. When this has been done, the spectator may lork with all hia eyes, but he caunot per ceive that anything is going on. There is no bubblii.g nor fizzing, nor any other noise or motion. The long row of vessels hang silently at Heir wire, Immersed in their tea, and nobody appears to pav any attention to them. And so they continue to bang for hours, for rive or six or seven hours, if the design is to produce worlc which w ill answer some oiher purposo than sell ing. All this time a most wonderful and mys terious piocecs Is going on. That gentle cur rent of electricity, noiseless and invisible as it is is taking the silver held in the solution, and iaviug it upon the surfaces of thooe vessels, within and without; aud at the same time it is decomposing the plates ol silver hanging along the sides of the troush in such a way as to keep np the strength of the solution. Wo cannot recover from the wonder into which the con templation of this process threw us. There are some things which the outside and occa sional obBervercan never be done luarvelliuK For our part, we never hear the click of a to e giaphic apparatus wlihout experiencing the anme. sna.-ui of astonishment as when we were firlt Introduced to that mystery. The beautiful manner too. in which this silvering work is done! The most delicate brush in the most svnVatbetio hand could not lay on the colors of the palate so evenly, nor could a crucible melt the metals into a completer oneness. And here is tne cpponum-j uve if it Were solid plate. Nay, it will look rather better; since the silver deposited by this exqui site process is perfectly pure, while tho silver. minutes an article is cu w.w, ,u every psrt, iuslde aud out; and that mere "bluah" of Pilver, as the platers, term It. will receive as bril i;i . rw.ii.h .n.i look as well (tor a monlhi as DECEMBER 5, 18G7. rmpt jed in solid wire Is o' the torn standard one-teiuh alloy.

Nor will 11 suflice lor the operator to attend to the strength of his solirioiis, aud keep Ins eje upon tho clork. As in certain conditions of the aimo spheie w e cau scarcely get a spark fiom the elec trle.Hl niHcbme, so there are times when the galvan'c batury works fccblv, and when the silvenng goes on much more slowly than nsual. To gusrd against errors from this cause, there is no sure resource but a sjstem of careful weigh ings. In such establishments as that of the Gorbam Company, ot Providence; Tifninv'8 or Hatighwoui's, of New York; Bailev's, ot Phila delphia; and bigelow Brothers' and Kennard's, or Palmer & Batchelder's. oi Boston, each article Is weighed before it Is immersed in iho solution, its Wfieht is ierorded, and it is allowed to rema'n tn tho solution until It has taken on the whole ol the precious metal it was designed to receive. There was a lawsuit ibe other day 1n New York, which turned upon the quantity of silver depos'ted upon sundry gross ot lorks and sp.ons. The rdatcr agreed to put upon them twelve ounces of silver to the gross, w hich is about as much as is ever deposited upon spoons or forks. It he bud performed his cou tract he would have spread over each tablespoon about as much silver as there is in a ten-cent piece; and such is the nature of silver that these spoons would have worn well for five or six years. In fact, there are no better plated spoons yet iu use than tltse were designed to be. The' plater meant to comply with the Ufages of tho trade. Ho m( oot to put upon those spoons the quantity of silver which, in the trade, stands for twelve oi.rces to the gros, which Is about ten ounces to the gross. Huch was probably bis virtuous intention, and he supposed ho had can led out that Intention. But when the spoons were put to the test, it was discovered that upon one hundred and forty-four tablespoons there were but three ounces and a half of 6ilver. It came out on the trial that the plater never weighed his work, and trusted wholly to the length ol time he It tt it in the solution. He appeared to be honestly indignant at the testimony showing that his spoons, which had been left four hours subject to the action of the battery, had ac quired only a film of silver. To the eye of the purchaser, theie spoons would have presented precisely the same appearance as the best plated ware in existence. For two or three months, or even tor six mouths, they would have retained their brilliancy. What their appearance would have been at the end of a year or two we need not say, for most readers have encjunteerd the spectacle in their pilgrimage through a world which is said to resemble plated articles of this quality in being "all a fleeting show.'' Eveiy one is f amiliar with the gold lining that is now io generally seen in silver vessels. This is laid on -by the same process as that which covers the outside with silver. The vessel is tilled with a solution of gold, and in this solu tion a thin plate of gold is suspended. The elec tric current being made to pass through the in terior thus prepared, the liquid bubbles up like soda-water, and in three or lour minutes enough gold is deposited upon the inside surface for the purpose designed. When this is accomplished ncthing remains but to polish the vessel, within and without, and we have a piece of ware which is silver when we look at it, and golden when we drink from it. The obstacle to the introduction of the supe rior plated ware now made by the Gorham Company is its costliness. The best plated waro. costs five times as mnch as the worst, and one-' fourth as much as solid silver. We saw the other day three large salvers, which at a dis tance of six feet, looked very nearly alike. All of them fore a most brilliant polish, and all were elaborately decorated. One of them was a trashy article, made of an alloy of lead and tin, coveied with a "blush" of silver. It had been stamped out and shaped at one blow by a stamping machine, and left in the silver solu tion subject to the action of the battery for per haps fifteen minutes. It was very heavy, and when it was suspended and struck it gave forth a dull leaden sound. The price of this abomina tion was $a7 60, and it would last, wit k careful occasional usage, tor a year. Dally use would disclose its real quality in a lew weeks. Another of these salvers was of solid silver, to which no objection could be made except that its price was $950. The third was of that superior plated ware introduced re cently by the Gorbam Company, of Provi dence. The base of this article was the metal now called nickel-silver a mixture of copper, nickel, and zinc a very hard and ringing com pound, perfectly white, and capable of high polish. Upon th'.s hard surface as much silver bad been deposited as upon the best Sheffield plated-ware, which is about as much as can be smoothly put upon it by the electro-plating pro cess. When the salver was struck, it rang like a bell, and it would not bend under the weight of a man. Such a salver, used continually, will retain its lustre for a whole generation, aud when, after that long period, it begins to lose its coaling, it can be rcsilvered and made as good as ever. But the price of this article was $200 more than five times the cost of the leaden traib, and a fourth ot the price of the solid salver. Nevertheless, plated-ware of this quality is the only kind which it is good economy to buy. There are few more extravagant pur chases we can make in housekeeping than lead and brass-ware covered with a film of silver so thin that an ounce of the precious metal can actually be spiead over two acres of it. One fact can easily be borne in mind; good serviceable plated articles cost, and must cost, fiom one-fourth to one-third as much as similar articles of solid silver. Anything of a much lower standard tbad this is trash and vulgarity. For our part we prefer good plated ware to solid plate. In plated ware we can now have all the beauty of form, all the brilliancy of sur face, all the durability aud utility of solid silver, without its excessive costliness, without appearing to be guilty of ostentation, without putting our neighbors to shame, and without offering a perpetual temptation to burglars.
