A Correspondent of the Post writes from London that an American by the 1 jp. name of Weils has invented a new mode ( f manufactuiing wollen cloth which will reduce the expense not less than three fourths. It is made without spindle and without loom and is fully equal to any spun or woven broadcloth. Our readers well know that hats have long been made of wo<?l without a single thread, and that the body of the manufactured article is more tirin and durable than any woven cloth. If it be a fact that three fourths of the labor may be saved by comj resting the ! wool instead of spilling it and weaving it, , theadvantage to tbiscountry will be greatcr than to any other in proportion as labor is higher here than elsewhere. The writer of the letter says:? About six months ago, I was introduced to an American who visited this country for the purpose of securing a valuable patent for a new method of inanufactring woollen cloth, all of which appears very well and possessed inijxirtnnt improvements over theEng!ish broadcloth,andcas- < simere: but as I know little about the article, I did not make any mention of it I, at that lime, for however sanguine an in- i, venter ofany new instrument may be, or | how ever convinced the discoverer of any , new the >ry or system may be, that it is ] superor lo all oth *rs. the public do not al- , ways find it to prove s ch. As tliis woollen . clotn is now ( Ifi red for sal* and as sever. al of the larjc London houses have pur. , chased hundreds of pieces for the purpr se , of introducing ir, 1 am justified in calling ( attention to it.? roe L ol >mai unznrc j, thus noticed the patent several months | since. "Mr. Wells has invented a machine and lias discovered a process by which | woollen clo!h of every sort is produced at less than a fourth of the cost hitherto usu^ a I. The material is not woven but comjtrcssed. Two urchins with the machine. ; can turn out one hundred yards of the broadcloth in twelve hours; and where twenty-four shillings were demanded per yard, six shillings afford the new manufacturers abundant remuneration. We have | inspected and handled, as roughly as wc , liked, specimens of every variety, from j the finest scarlet cloth for officers' uni- | forms, down to blankets and carpets, and , we certainly could not, cither by sight or touch distinguish them from correspond- < ing pieces made in the old fashion." The new cloth is likely to create a ' | great revolution among the manufactn- ? rers, for already they discover that it is !, something more than a mere bubble of an j ( hour. The Austrian government has purchased the right to manufacture in | Austria, and several other rights to manufacture it in England and France have also been purchased. There arc four or | five large mills now in constant operation | in this country, which turn out daily sev- ' 1 eral hundred pieces of the cloth of various : r qualities. Soon the markets here will ij lie filled with it, and no doubt a large quantity will be sold in the United States j | as Mr. Wells, who is a New Yorker, in- j formed me that so soon as he bad com- j pleted all his arrangements for supplying I j the European markets, he should establish j, several large factories in America. Mr. j i Wells has worn a frock coat made of his new cloth, almost every day during the . last six months, and it is an elegant garment even now?the material being 1; compressed, there is no thread in it, and the nap has the same smooth, glossy a p. 1 pcarance as when I first looked at it.? j The cheapness, durability, and beautiful | appearance of this cloth must give it a de- 1 cided advantage over ail other kinds. So !, far it has met with great favor from the! most extensive dealers in cloths in London. From the Kentucky Farmer. IMPROVED BREEDS OF HOGS. There has been much controversy in Kentucky in reference to the relative merits of the various breeds of improved hogs; and the subject has indeed engendered some of the spirit of partizansliip. It is not our purpose to tak$ a side in the controversy; being determined to deal ; with the utmost impartiality towards the I the advocates of each of the various | breeds. Our object shall he, in conduct-' ing this paper, to take such a course as will serve to bring out the facts referring to the merits of till subjects in which the I \V . 1 li 4 C"H? farmer is interested. While we deem an honest collision of sentiment favorable to the investigation of truth; we deprecate that partizan spirit which has an exceedingly keen vision in looking at one side of a subject and is utterly blind in viewing the other. Long ago, and repeatedly since, we proposed a test by which the relative merits of the various breeds of hogs could be satisfactorily ascertained; and that was, to rear a large number of each breed, under the usual mode of treatment which the country is> compelled to adopt, noting carefully all the facts involved in the experiment. When this proposition was first made, it was ohjected, that the demand for blooded pigs, for breeders, was too great to allow a sufficient number of them to be devoted to the experiment.? The "pig business" is indeed too profitable to be abandoned for the sake of making experiments and we have strong doubts whether any of the prominent breeders of the various vaunted breeds can ever be induced to go into such an experiment as is proposed. But the object can be effected in spite of them and without their co-operation. Many farmers have purchased blooded pigs, not for the purpose of going into the "pig busines," but of improv ing their stock; and they will rear their progeny, not under the stuffing and gorging system, but in the usual way, and the results of such treatment will indicate the best breeds. It cannot be long till we shall have reports of practical experiments, showing the entire treatment, the ages, the amount of food consumed, the weights attained, travelling qualities, &c. &c. This is the kind of information we have sought to elicit, because we believe it to be the only satisfactory kind. We have some facts, relating to various breeds, which we take the liberty of gleaning from our private correspondence, believing that the writers can have no objection to their publication. The facts are interesting in themselves and may i lead to the development of others more exit nml tlofVi r- f r>r ** We begin with the statement of an ex- [ periment hv 4/r. H. P. (i ray of Woodford, , made in the usual practice of rearing hogs. ! It will be recollected that we published ' an experiment (Vol. 3, p. 142.) of this I gentleman upon half blood Thin rinds, | highly favorable to that breed. The pres. i eut experiment relates to some pigs by an j Irish boar out of half blood Thin rind hows and a comparison between them nul some pigs of scrub breed. The result will astound two classes of men.?those who deny the great superiority of blood and those who affect to ridicule the Irish iind Thin rind hogs, for neither of them ire now considered tlie, "fashionable" breed. We hove the notes before us furnished by Mr. Gray and no one who knows him will doubt the correctness of his statemen's. And it is proper to say that he is not a "pig dealer;" his hogs were reared and killed for the use of his own family; J and no one must regard this notice either ! as a "putf or an advertisement in disguise." He killed 4G hogs last fall. Of these, J2 were scrubs, pigged in October 1^39; the residue were out of half blood Thin rind sows by an Irish hoar, 22 of them j pigged in January 1840, and the other \ two pigged in October 1839 about the I lime of the scrubs. The scrub pigs were j well wintered in the usual way; and as , ?oon as the blooded pigs were weaned, the j whole 40 were turned together and well treated. The clover was good but the rye | was very indifferent [nobody grew good rye last summer.] The whole were put jp together in a pen on the 15th of Sept. 1840, to b * fattened on corn. Now mark the result. The 22 blooded pigs, pigged in January 1840, slaughtered November 19, ten months old, weighed neat, 5120 pounds, being an average of 232 pounds each, j neat. The 22scrubs, pigged in October 1839, slaughtered December 17, near a month later, when fourteen months old, weighed neat, 3930 pounds, being an average of 178 pounds each, neat. So the scrubs, four months older, and fed on corn near a month longer, averaged each, 54 pounds less than the average of the blooded pigs. The two blooded pigs, pigged about the same time of the scrubs, and killed a month sooner, weighed respectively, 300 and 298 pounds, neat. The heaviest blooded pig weighed, neat, 290 pounds, the lightest, 192; the heaviest scrub, 206, lightest, 104. These facts need no comment; they speak for themselves and every farmer can make his own calculations as to the relative value of blooded and common pig??. Tlie scrub pigs were considered of good stock; and we presume the weights they attained will prove them equal to the average of common hogs. Mr. Joseph lteed, of Montgomery county, had G pigs, pigged about the first of April, by Dr. Combs' Berkshire boar, out of a common sow, which averaged 175 lbs. neat, killed about the middle of November, when seven and a half months old?ordinary treatment. We will now quote from a letter by Dr. Martin, dated Dec. 7, 1840. He is a distinguished breeder of cattle and various O t breeds of hogs, but is understood to be an advocate of the Woburnhogs: "Now for avoirdupois. I sold to Henry Savory, five hogs of Woburn blood, . i ? ??MM itt r vs>' MfM RAW, SOUTH-CAROLINA that were two and three years old?the three year olds had been used as boars.? No. 1, weighed 640 lbs; No. 2, 630; No. 3, 660; No. 4,748; No. 5, 824. 7 1-2 off each for weight of breeching?I have sent I r this to the Kentucky Farmer. I had some pigs, pigged 23rd of last December; they were kept with their mother, after some cattle, until April, when they were turned on grass, and 1st Jnly upon rye that was less than two bushI els to the acre, (what was cut and I cut ^ i Jhe best of it,) after which about a hun- ,! dred were turned upon a stubblefield and they had access to an apple orchard of one hundred trees, winter fruit, very little down until a storm 3rd of October. They stayed here until put up to fatten j and were killed 17th November and I weighed neat meat 261. These were the | refuse of the Woburns?I dont know | | what the best wonld have done. I killed j i a pig, a little older than Gov. Wickliffe's | boar which was pigged 14th February,! with same kind of treatment as the last, that weighed 250 lbs. neat. I killed a refuse pig, much the least in the litter, pigged 14th 3/ay, half white Berkshire and half Woburn?killed Nov. 17, that j weighed 110 neat meat. The best of this | litter. I think, (a mere matter of opinion,) ' would have weighed 200 lbs. each." The statement in reference to the big hogs, so far as relates to the expense of their keep, the quantity of food consumed, and the length of time they were fully fed, is about as definite and satisfactory as the phrase?"big as apiece of chalk." And the Doctor had been more satisfactory, in reference to the pigs, had he staled the length of time they were corn fed. Our next quotation is from a letter by j A. B. Allen, Esq. of Buffalo, New York, l a distinguished breeder and advocate of. i Berkshire hogs, under dale, Columbus, O. | December 9, 1840; and we are glad to 1 find one so eminent, concurring in our. 1 I views as the proper mode of ascertaining j the real merits of the various breeds. "But to return to Berksliires. I know that the Woburns can boat the present Berkshire's* in weight at the same ago. J but that is nothing. The only fair and j < I proper test would ue sucn as you propose, 50 or 100 head of each grown up and fatted in the common farming way of the conntry, an accurate account kept of their food and then see which has given the most and best pork for it;*nothing less than this would be satisfactory. But can Dr. Martin sh< w a gain of upwards of three months, of three pounds per day, as the Brentnalls m.ade a Berkshire harrow do last winter? Vide their statement in March or April number of the Cultivator. [ have just made a most superb importn. tion from England and have every satisfactory evidence from the persons who , bred them, that the families from which ; they are derived will gain 1 3-4 to 2 lb. pr. day, made harrows and shoved in their feed, for the first year of their lives. A pair of pigs, sent with one of the sows, has gained since littered in April 1 3-4 lbs. per day each up to the present time, and one of the hoars actually weighed on the scales, on arrival, 520 lbs. at 18 months old, though thin in flesh. My brother will make a statement of them either in his own or my name, for December or January No. of the Cultivator. They had not arrived when I left but he says they show great vigor and constitution; and, notwith* ..4.. /? tU.v.f a(?*A AI>A nnnn I in fl nOnOWQ SMatlllll Ug lllUil 316^1 UIV . of point to my very best Shaker and other I stock. The oldest boar, he adds, is superior to any thing he ever saw, not excepting the last sent out by Hawes to Lossing and the Brentnalls?their color and characteristics same as Hawes' importations. The stock of my Prince Regent, imported last fall, has proved very tine and has taken premiums wherever exhibited, but it is hardly large enough to suit Kentucky. In this valley, [the Scioto] and in New I York, 'tis much admired. Breeders here j tell me they dont want a bigger hog than \ J300 lbs. at 18 months; and a few large i Berkshires I brought down wont sell at all among them, while the medium size go | rapidly. As to their driving, I. know the longest legged ones cant be beaten in mad 1 or any where else. I give you an extract i of a letter just received from John Mahard (jr. of Cincinnati, one of the largest pork i packers there. He wrote me unsolicited ; in the way of business: We have just got through cutting and | packing 1280 hogs, for J. B. Kenney, Esq. and others, who drove them from near Georgetown, Ky., a distance of about 80 to 100 miles and in the drove they had five or six half blood Berkshires and they stated that they stood the journey better than any other hogs in the drove; and al| though several of the common hogs gave i out and had to he left behind, every one of the half Herkshircs came safe through to market.' To be sure this is but a small and partial experiment, but it goes to prove my assertions regarding their driving qualities; and as .Mr. Kenny is one of your neighbors, I suggest your obtaining the statement from him and publishing it." We shall conclude now, by an extract from a letter written by a gentleman of Madison (that great hog raising county) to a correspondent in Clarke, who transcribed it in a private letter under date December 23, but with no view of its I publication. As to the conclusions of ! the writer, favorable to one breed and unJ favorable to others, they would carry i^??1 1 CUf W SBWMJBWR i, WEDNESDAY, MJK< more weight, had he stated the facts and grounds on which they are based. But the writer appears to have exerted and active spirit of investigation and he, too, coincides with us, that the gorging system does not furnish the true test. We would thank him for his facts. "i>/r. and myself endeavored at the Winchester fair to determine which, among the several rival breeds of hogs, is the best. We carefully examined the specimens of each that were exhibited dhere, and concluded that the veFy-besl of each, reared in the best manner, is nol a fair test of their relative value or of theii merits; because we sometimes see individual animals possessing that conformation which experience has proved constitutes them the most valuable of their species, which has been the result of aecidenl aided by extraordinary care and ju Jgmcnl in rearing, and is not a characteristic ol their race. It is son otimes the case too that this form is imparted by a single cros; and never appears in their progeny. Ii is a fact also, that one particular breed o line animals, crossed upon an inferioi race, will make a great improvement. Wt therefore determined that the best mod( of settling this matter would be to examine those different breeds in general and no in particular individuals; to see them un der indifferent as well as good treatment and inspect the cross of each upon ou common stock kept as slock hogs genera! ly are. This course of examination W( commenced at your house. We hav< since looked at other herds. We hav< seen the cross of the Wohurn, the Berk shire and the (hazier, upon the varioui breeds of scrub hogs, and after a tcdiou: and rigid investigation of the claims of al of them, through their crosses and it themselves, lor all the purposes for whicl they are designed, we unhesitatingly pro noiincc the Woburn the best hog. W< have seen them crossed in every way am the result has been invariably, an obviou and decided improvement. I could giv< you some facts in relation to othor favorit breeds, crossed upon the scrubs, of whicl perhaps you are not apprised, that detrac much from their merit and high standin; in mv esteem; hut as you arc the owac of all those different breeds, I will sa; nothing here npon that subject." This is strong language ami we repea that the wiiter should substantiate hi opinions by the facts. We hive now had the various breed long enough to judge of them by their rea merits; and we repeat our call for facts ascertained in practice. VVe mean h show fair play and do full justice to all and if the facts regarding the merits am relative value of each of the vaunte< breeds, be not made known, it shall be th< fault of the breeders themselves. Givi us, then, facts, proving the superiority o your va.ious breeds. Slate your treat ment fully*and fairly and then give u vmir nrrriiments in avoirdunois. No hum bugging pufis will be admitted; we h;iv< had, in all conscience, too much of then already. Intelligible, practical facts an now due; let's have them. From the Farmer's Register. Inquiries and Remarks on Salt, as . Manure, and especially for Cotton. ' llavc you seen a late English work 'Johnson on Fertilizers,' it which he dis cusses some recent experiments in tha country on salt as n manure? particular ly in combination with compost, Ihrm-yan manure or lime. They arc so importnn that I am anxious to see them transcribe) into your useful periodical. He is spokei of in the 'Library of Useful Knowledge, ns high authority, and if lie is to be cred itcd, suit would be cheap manure at twi dollars a bushel. Besides, he recommend it so highly for destroying weeds, if pu on a season in advance of the crop, am for destroying worms and other insect infesting a crop, that I am desirous to se it in print, that experiments may bcgii extensively thro' this country. I shouli not he surprised, from his trials, that a top dressing of a bushel an acre, sown ove cotton in Juno, should destroy the worn which has so dreadfully consumed on crops in the South. At that season of th crop, the worm is burrowed about six o seven inches deep in holes made in tin ground; and he informs us that worms ii that situation arc certainly destroyed b salt in small quantities thrown over th earth." The foregoing extract is from the lcttc of a distinguished Southern planter, whosi name we are always please I to prcsen with*his communications, whenever no forbidden by his order, as in tiie presen case. The essay of Johnson, on salt as a ma nure, would have been published lon< ago, but from our want of confidence ii his opinions. Upon the desire express? above, we shall take an early opportunity to publish cither Johnson's own article, o his and others opinions on that subject, a given in the 'Farmers' Scries' of the Li brary of Useful Knowledge.' The use c salt as a manure has been frequently urged, upon the ground of great benefit produced by it in parlieu'ar cases. I has often excited the hopes and enlistei the active zeal of some theoretical writers and again fallen into negl :ct, because o failures iu practice. As a general prac ticc, salting land for its fertilization, a any rate of quantity, has not been foum advantageous or profitable. But even i not a general fertilizer of soil at ail, stil aaa. 311 31, 1841, I it may be highiy beneficial as a destroyer : of predatory insects, (if taking care not to give so strong a dose as to injure the crop on the land,) and still more probably i as a specific manure, or food essential for 1 certaiu crops. This last opinion we have long entertained, and have before expressi ed it in this journal, as well as we have , published every known fact on this very t important point. Many plants cannot grow except on a salt soil. There is no I doubt that salt is a specific manure for asparagus, and there is a good reason to t believe that it is also a specific manure for the very important crop, cotton, On . the latter head, see articles at page 677, vol. iv., and pages 45 and 46, vol. v.? j The two first we copied from the'Southern Agriculturist.' The last, our (editorial t I remarks ) being short, will here be copt i ied: f "It seems to us that salt must act as a , specific manure for cotton, and is esseni tial to produce the fineness of fibre that t constitutes the value of the sea island cotf ? J!?r A. __ I? .i._ i:,.. i i ion. /\s uiu:;reiu us urc inu ijuumjr aim r appearance of this cotton from the green i seed, or short staple upland cotton, they ) are but varieties of the same kind, the : most of which, rapidly runs into the other, t by a mere change of soil. The one kind - is raised, in perfection, only on the low . sandy islands on the sea const of Georgia r and South Carolina, and the adjacent - shores of the main land. If the seeds J (which are naked and black,)are planted > in the interior, though but little remote - from the sea, the product is what is called - the "Jong staple Santee," a green seed s cotton, but of longer fibre than the ordinus ry upland cotton, into which, however. I continued planting from the same, fiually i brings the crop. i "It has been supposed that the very san dy nature of the soil of the sea islands was ii the cause of the peculiar value of the cot. J Ion which they bear. Hut if so, some s spots, at least, might be found equally san. u dy in the interior of the country, and the i' same kind of cotton be there produced i successfully. But the accounts wc have t in the foregoing and other articles of the * peculiar value of salt mud and salt grass r as manure for cotton, indicate plainly that v. salt itself is necessary for the perfection ol cotton, and that it is owing to the salt al t ready in the soil of the sea islands, and th< s adjacent low coast, that to such narrow limits the production of that valuable vari s etv of cotton has heretofore been con I fined." 1, In what manner specific manures acl -y upon the plants for which they are eithei ; very important or essential, has not been j saiicfactorily explained in any case. The 1 'acts, however, are not the less certain, in 2 the ascertained cases; and there may lie 5 many otheras important cases, which have f not yet been observed. Thus carbonate - of lime, or some equally serviceable form s of combination of liine, and in considcra. ' hie quantity in the soil, is essential a; to the growth of clover. Gypsum i ' (sulphate of liino) is another important e ! specific manure for clover, but not as ; indispensable to its existence as othci | forms of lime. The acid of earth, which is a poison to valuable crops, is indis' pensable food, or a specific manure, foi j sorrel, poverty grass, and some kind ol pine trees?none of which can live aftci t j this acid has been effectually neutralized _ | by manuring with lime* If then, though (| in a less essential degree, salt is a speci. t fic manu c for cotton, it may well b< cj that a very sinallqnantity may produce im i portant improvements to the growth ?; though no other culiivated crop might re _ ceive any perceptible benefit from a lik< ; application. ^ I From the Jour, of the Am. Silk Society, I i E oioon's Addutss to Silk Cu lour its ' ?We enter upon tlie publication of th< e Silk Journal another year, with no litth n i anxiety and trepidation. We hav< j ! not one-fourth the number of subscriber.' necessary to pay the expenses of the pub r lication ; but what we lack in number o ? subscribers, is made up in hope?hope r | that the good cause in which we are en e g?'igcd will yet be sufficiently prosperous t< r afford us the means of publishing th< 3 1 Journnl; hoj?e, that the people of the Uni n [ ted Slates will not neglect so great and s< v good an opportunity of benefitting them u ' selves and their country, as the culture o ; silk affords; and that in turning their at r ; tention to it, the Journal will be consider e ! ed by thein, one of the mast im porta n t i aids to the attainment of the great object I [ Wc therefore, once more launch our litth t bark for another voyuge and trust to th< good sense of the people, who are to b< exclusively benefitted, for a sufficient sup 7 ply of small starts to support us to the cm n of it. ^ Silk will yet become one of the tbro< v great staples of the country ; nothing cat r prevent this. Enough has already beer s j done to ensure that result. But whethei . I it shall become so sooner or laJer% dependi upon the exertions now made and makini y to accomplish it. If the people will lake s hold of it with spirit, it can be nude tc t lake this place in four or five years; if ii ^ must be permitted to work its own wav , into favour, by the force merely of tfic f persevering example of q fc\v pptfdlofs, il . will require a much longer time, t We have hcretoifore discussed the obj jection made to the culture of silk, on the f score of the comparative high price of la. |j bour hero. The objectors sa^', * labour if - - > a NUMBER 20. too high in this country for us to u=eit in making silk.' Is not the labour applied i" making every thing else, as high as that of making silk ? How can we make oot, ton goods, or woollen goods; how can we inake6rtc&, (formerly imported, as well as silk, (if the price of our labour is too high ? This argument is fallacious. It is not the price of labour that precludes the production of any article, but the scarcity of enterprize, and ingenuity, of a want of a proper direction of them. A new country will likely to enter upon the production of articles of luxury, the whole attention of their enterprizing and ingenious men being occupied in producing necessaries ; but as soon as a supply of these is secured, or the number of such men is increased, then the production of luxuries will commence, in spite of the price of labour, and the opposition of apt}-, thetic croakers. That silk will be a profitable pursuit we have not now, and never had, a single doubt. But like all other pursuits, it must be fdlowed by business men in a * ? ? nr?_ I Diisiness.iiKC manner. 10 iuuko uiuucjr from the culture of silk, requires a due degrce of enterprize, perseverance, skill, and economy?nothing more. And in what other pursuit can money be made without nil these ? Wc are told, that the failures Inst season were so numerous that, at b->st, the business will he a precarious one. We > do not draw the same conclu.- on from the same premises. On the contrary, wo consider the failures of last season the natural result of natural causes, which can be and of course will be avoided. Ifgencral success had attended all the experiments last year, it would have been a phenomenon worthy of beiog called the eighth wonder. We are only astonished* that we ever could have expected any i thing better than what happened. Let us look at the subject for a moment. Those ! who attempted the making of silk, with - very few exceptions, went into it blindfold i as it were, without experience, with very I little knowledge, and with the worst pos! sihlc and conceivable means. They were in the fitful delirium consequent upon the , excitement of the tree mania; they were t misled by interested advisers as to the skill f required in raising and managing worms, and as to the profit to be made; and added j to all this, they were unfortunately sup, r plied with bad eggs, and still more unfor. tunatcly, badly advised as to their man agement. And wc may add another to the list of causes ; nearly the whole supply ? of leaves was derived from young imma lure trees, which, of itself, would have i been considered in any other country a i sufficient cause for all the misfortunes, i that happened. Nearly all these causes of ! failure may be avoided another season ; all indeed, except the supply of eggs, and the proper mode of keeping them, for sue,. i cessive cropn. There are few good eggs . in tin? country, and still fewer adapted to ... . J 9 ? the production of successive crops; but i there are enough to enable this year to efc, : tablish the silk culture upon a firm basis, ; It will he our business, and our pleasure, ' during the present season, to collect and i distribute all the information on the sub. > ject that shall come within our reach. We shall continue to receive from Franco, f early information of all improvements iq, ' machinery and in practice; and we shall I leave no source of i.forn.a ion unappealed i to for the same purpose. Once more, therefore, we appeal to the. } friends of the good cause to aid us. Tq . every one of thein we appeal lo get all the , sub. cribers they can for the Journal. As we are not begging for our own benefit, 3 but for the ben* fit of those who give, we are n< t ashamed to say, that we will re. ccive contributions to aid in the public^? tionof the Journal.
