by this and the printing-presses of Caxton. Then Spenser delighted by his sweet imagery; and that mighty bard appeared who wrote “not for an age but for all time.” of whom the lecturer said, quoting the language which Shakspeare puts into the mouth of Antony, “he makes hungry where most he satisfies.” The lecturer also referred to the poets of the 17th century, passing a glowing eulogy on Milton, and specially commending Pope’s “gems of wisdom.” The peculiarities of subsequent poets were adverted to, and Burns and Cowper, and Crabbe, and Moore, were passed in review. Scott's marvellous powers of dealing with the legendary and the chivalrous were enforced, and Byron's magical genius received due recognition. The lake poets were reviewed; Wordsworth receiving special reference and homage. The poets, male and female, of the present day, were glanced at ; the lecturer leaning to the notion that the female poets have the supremacy in inspiration. The concluding portion of the lecture was an elaborate vindication of poetry from the attacks of its detractors. There are some who detest “ballad-mongers; ” who regard them as merely frivolous and useless writers. If they are correct in their opinion, the lecturer said, the Homers, and Virgils, and Wordsworths, and Cowpers, and Miltons, and Shakspeares lived in vain; and the man who could seriously assert this would display not his wisdom, but his eccentricity and temerity. He dwelt on the good that results from emotional appeals, and from the merely beautiful. He showed the poetical in nature around us, insisted upon its utility, and with considerable warmth and energy compared and contrasted natural with artistic beauty. Poetry, so believed, meets a requirement in the nature of man; and will last as long as man has spiritual thoughts, as long as he is influenced by hope and love, as long as he owns bright anticipations, as long as he is surrounded by suggestive solemnities, and as long as he is the participator of “the mystery” of existence.

SEvenoaks.—On Thursday, November 10th, a lecture was delivered by Dr. Vesalius Pettigrew, at the Literary and Scientific Institution, on “The Advantages of the Lower Animals to Man.” To illustrate this lecture those animals were chosen whose province it is to clear away all decayed animal and vegetable matter—“scavengers,” as the Doctor humourously called them—the worm, the beetle, the fly (blue-bottle), the star-fish, the adjutant, the hyena, &c., &c. This is the third lecture the Doctor has given to this Institution, all of which have been numerously and respectably attended. The Marquis of Camden has taken the chair on each occasion.

SHREwsputy.—On Tuesday, November 8, Mr. Elsmere delivered his first lecture on Botany and Vegetable Physiology, to the members of the Shropshire Mechanics Institution. The subjects of the lecture were—The Nature and Uses of Botany; the Germination of the Seed; the Root, and its various Uses; the Stem, its Functions and Anatomy. In conclusion, the lecturer remarked that the vegetable world afforded us satisfactory proof of the existence and goodness of God, and furnished unanswer. able arguments to atheistical sophistries. At the close of the lecture a vote of thanks was proposed by the president, and carried by acclamation.

St. LEONARD's-on-SEA.—The annual soirée of the Mechanics' Institution was held on Tuesday week in the Assembly Rooms, and was very numerously attended. The president of the Institution, Mr. Alfred Burton, occu|...} the chair, and was supported by many of the eading residents of the place. . S. Putland, jun., read the report, from which it appeared that the number ofsubscribing members was 184, having been 170 at the corresponding period last year. In addition to these there were ten life members. he library consists of about 850 vols The reading-room is lo with three daily and three weekly newspapers, and five weekly and one monthly periodicals. he Local Exhibition, held in the same rooms in January and February last, was visited by upwards of

4000 persons, and the receipts netted £80, which sum was carried to the credit of a fund for a new building, which the Institution hoped to be able to erect on a scale commensurate with the rising prosperity of the town. Valuable results are looked forward to from the union with the Society of Arts. The president then addressed the meeting, and was followed by the president of the Hastings Mechanics' Institution (George Scrivens, Esq.), the Rev. W. W. Hume, Mr. Selway, Mr. Banks, Mr. Ward; and by Mr. Tufnell, the Government Inspector of Schools, who was a visitor on the occasion. A vote of thanks to the chairman was proposed by Sir Woodbine Parish, K.C.H., and seconded by P. O'Callaghan, &c.

WARMINstER.—The first lecture of the season at the Athenaeum, was delivered on Tuesday, the 4th Oct., by Mr. Ansell, on the “Electric Telegraph.” The lecturer did not confine himself to the mere exhibition of an instrument, and of those aerial highways of words—those mysterious threads—which we see at railway stations and along the lines of our chemins defer—our iron roads. He went backfar into antiquity, to give, historically, an account of all the successive modes of signals which nations have adopted; commencing with the Siege of Troy, and ending with the era of railroads—embracing beacon fires, semaphores, and all the various modes of telegraphic communication under whatever mode of operation they might have been in use—showing their greater or lesser value in simplicity and intelligence—their sufficiency, or insufficiency through gloom and fogs, by land and sea. . The lecturer brought a staff of operators, who communicated messages from the lecture-desk to the gallery. The locture was highly appreciated.—On Monday the 16th, Mr. Bird lectured on Asteroids, and luminous and shooting stars.” The lecturer discussed the theories of the most eminent astronomers who have written upon that branch of astronomical science of which his lecture treated. The theory of Obers, in particular, as to a lost world was noticed, and its probabilitics presumed.

NOTICE.-The Council desire to call the attention of the Members and others to the increase which has been made in the size of the Journal, by the addition of four pages of matter. This addition will be given every week during the session, when the papers read at any of the ordinary meetings run to such a length as would preclude, under other circumstances, the publication of shorter articles and letters of general interest on the subjects embraced within the Society's operations. The Council trust to receive the cordial support of the general body, to enable them to carry out, with increased and increasing interest, this feature.

CAPT. PEACOCR's PATENT BELL BUoys.-Three of these buoys are now in the Southampton dock, which the Mexican vernment have ordered for a part of the coast in the Gulf of exico. They are enormous buoys, with large bells, and their use is in thick and foggy weather, when the buoys cannot be seen. The surging of the waves causes the bells to ring, which givesinsormation of the locality of the buoys. The apparatus is such also as to answer the purpose of life buoys, where several persons can be sheltered until they are rescued. The Russian government recently ordered one of the patentee for Riga. One is placed off Calshot Castle, near the entrance of the Southampton Water, and it has been proposed to place one near the entrance of the Solent, which would afford great assistance to the to: and commanders of the Southampton mail packets, lonel Facio visited Southampton on Monday, to inspect the buoys for the Mexican government. Captain Peacock has recently submitted models of his very ioinvention to the Admiralty and Trinity Board. CoMMUNICATION BETweeN THE GUARD ANd DRIVER of A Railway TRAIN.—Captain Norton proposes that a Whistling Bolt or Arrow, without feathers, should be shot from a steel cross-bow by the guard of the train, a few yards in a direct line ofer the head of the engine driver, who should have a shield or a *Teen behind, reaching a foot above his head. The guard could place the bow on the roof of the carriage in his front—in a position marked out, so that every shot would follow the same to without the necessity of raising the bow to his shoulder of taking any aim. Captain Norton has also invented a new Foignal. This apparatus consists of a small piece of seasoned wood, such as ash or elm, which has a chamber drilled into it, to receive about three drachms of Hall's rifle-powder: this hole is opped with a wooden plug, glued in. A small touch-hole on the side receives a quill, charged like that for firing a cannon by Percussion, but more simple in its construction—being without the transversequill. The fault of the fog-signal at present in use is, that the tin case containing the charge of percussion Powder, is crushed by the wheel of i. engine; the percussion o: is in consequence not confined when the explosion takes

Cossolidated Sopa WATER.—A curiosity in saline drinkstermed by the inventor, M. Lamplough, consolidated soda water-has just made its appearance. Aerated, or gassed, water is common enough, but not so real soda water. M.

Before proceeding to discuss the more prominent means now in use, for extracting the noble metal from the substances with which it is found assotiated, it will be well (very briefly) to consider the conditions in which gold presents itself in the various localities where it is found. It has often been remarked, as an evidence of he wise care of Providence, that while gold, which possessed a comparatively artificial value, existed but in small quantities and in few localities, iron, the most useful of metals, was distrilood in vast quantities in every quarter of the globe, and was everywhere accessible to man. The present appearance of things would seem to tlow some doubt over the truth of this remark, Which would appear to be more pious than just. The fact is that gold is found in every Tarter of the world, and every day's research "I'lls new fields to the enterprise of the *ker. The authority of a year on this *lict is already out of date. California, * gold fields were opened only six years *3% had hardly successfully asserted its claim to the title of the Eldorado, before she found a Powerful rival in your own Australia; and even this seems destined to share attractions with Devonshire and Wales. The most ancient source of the precious metal mentioned in the sacred writings, is “the had of Havilah, where there is gold,” and of which it is said “the gold of that land is good." of Ophir, we are told that “ they fetched from o gold and brought it to Solomon,” and that "chophat made ships to go to Ophir for gold;" but We know not with certainty the situation of Ophir, nor have we the means of ascertaining

in what form the metal presented itself, or whether the diggers of those ancient days reduced it by means of crushers, cradles, or long-toms. In later times, Africa was long a noted source of gold, which gave a name, indeed, to a large portion of its coast. . The metal was found in smallparticles, known in commerce as “gold dust,” collected, no doubt, by some rude process of washing, from the sands in the beds of the intermittent streams. The region on the south of the Sahara, as also Sofala and Kordofan, were prolific sources of the precious metal. Sofala has, indeed, by some been supposed to be the ancient Ophir, and was long the chief emporium of the gold brought from the interior. But Africa is now entirely eclipsed by our modern Eldorados. It is said to yield about 5,000 lbs. weight annually. Asia has long been, and still continues to be, an important source of gold; indeed it was brought from the Indian Islands in remote times, and more recently gold deposits have been extensively worked in the Siberian and Ural districts. In the Ural it is found in small pieces, embedded in coarse gravel, and in veins of quartz in hard rocks. It is sometimes found associated with platinum. America, too, has made her full contribution to the stock of the noble metal. Brazil, Chili, Peru, Ecuador, New Granada, have all yielded rich supplies. The streams which run from the mountains bring down their precious freight in their pebbly beds. These were for a long time the chief sources of Brazilian gold, but it is also found in veins in the rocks, which modern capital is making available and profitable. The quantity yielded in Mexico is comparatively small, and it is always found there associated with silver. The Apalachian chain of the United States sends downs in some of its streams quantities of auriferous deposits, which have been worked with advantage in Virginia, the Carolinas, and Georgia. But all the gold fields of America sink into comparative insignificance before the immense yield of the single state of California; which, in six years, has transformed a wilderness into a populous and wealthy, state, with agriculture, arts, and commerce. The gold discovery here took the usual course. It originated in accident got wind against the will of the first discoverer. was kept alive by rich findings in alluvial deposits. and at last subsided into something like a regular branch of industry; into which more perfect methods were introduced, as the eagerly sought wealth began to demand for its attainment a more steady and laborious industry. Rich sands and nuggets gave place to quartz ore, which required to be mined with great labour—crushed by heavy machinery, and amalgamated by careful and expensive processes. In Europe, gold is found in many localities;

the principal of which are Hungary and Transyl.

2d, , , A specimen of Cornish ore yielded at the rate of 11 oz. 13 dwts, and 8 grains to the ton. The Poltimore gossan has yielded from 17 to 32 dwt.s. to the ton, and other Devonshire ore 9 ounces to the ton. These results have been obtained within the last month, and go to show that the long-cherished dream of finding gold in profitable quantities in England is about to be realized. The experiments just mentioned have all been made at an expense not exceeding 5s. the ton for the reduction. The same ores have been smelted at a cost of 30s. per ton. A word on the subject of England's great gold producing colony, will conclude these hasty preliminary observations. Australia has only been known as a goldproducing country since 1851; for although shepherds and others were known to have picked up stray pieces of gold-bearing quartz for some years previously, it was not suspected to exist in quantities sufficient to repay the labour of collection, until Mr. Hargreaves, a practical miner, who had gained his experience in the Californian gold-fields, showed that the metal could be obtained in large quantities on the western slopes of the Blue Mountain Range. Subsequent researches have proved the metal to exist in larger or smaller quantities throughout the settled districts of South-Eastern Australia; and, from the character of the ranges to the north of New South Wales, it is suspected that they will prove equally prolific. Hitherto the metal has been obtained solely by the simple process of washing; for, although machinery has been introduced by public companies for the purpose of extracting it from the quartz rock, no important results have yet been attained. Indeed, in the first instance, the metal appears to have been sought for only in the alluvium, until the discovery of a monster nugget,

[ocr errors]

consisting of nearly a hundred weight of gold, in a quartz-ridge near Bathurst, called attention to the parent rock; and the subsequent researches of the Government geologists brought to light veins of auriferous quartz so extensively diffused, that quartz mining must soon become one of the chief industrial employments of South-Eastern Australia.

Notwithstanding this extensive distribution of gold, and the great desire of man to become possessed of it, the methods which human invention has hitherto devised for the purpose of obtaining it, have been but partially successful.

| There is abundant evidence to show that, up to

the present time, no method that has been applied has succeeded in extracting all the precious metal from auriferous ores. A friend of my own, who has travelled extensively in Russia, states that a very large proportion of the wealth of the Russian ores is lost—by confession of the mining men themselves—in the process of reduction now employed, and which has been cited, by an emineit geologist and mining engineer, as the most perfect process now in use. In California, too, the loss of gold has long been loudly complained of Mr. Collins, of Grassvalley, in that state, says:– “Our present mode of operating is very rapid, but the process of saving the gold is very imperfect, not saving from ordinary rock more than one-fourth or one-third of the gold which it contains.” The Phoenix Gold Mining Company of New York, in their report, make the following remarks:—“The difficulty hitherto in gold mining from quartz has not been chiefly in breaking, grinding, and pulverizing the rock,--that is in itself a very simple process, and one which can be effected in a variety of ways, with a per centage of difference in rapidity; but, after the rock is pulverized, the great desideratum is to separate the whole of the gold from the powder. The old process is so incomplete in its results that not more than one-sixth to one-third of the gold is saved in practice, as shown by the more thorough assay of the chemist.” Volumes of evidence might be added on this subject, all of the same tenor, but the simple fact that there has been so much inventive ingenuity applied in the last few years to the production of machinery for extracting gold from its ores, is sufficient to show that a machine for the purpose of doing this work effectually, remained a desi

deratum. This leads at once to the consideration of some of the methods hitherto employed for this purpose. Their number is so great that it would be impossible, in the proper limits of a paper like this, to specify them all. It will only be attempted here to indicate such as seem to be types of whole classes of appliances of the same general character. The processes for securing gold may be divided mainly into Washing, Smelting, Amalgamation.
