It is conceded as an axiom, that theory and practice, in the pursuit of any object, are in their natures es- sentially different and distinct. But at the same time they long for a mutual understanding each to confirm the assertions of the other, the consummation of all practical results being the mutual embrace and per- fect reconciliation of these two attributes. The writer of these pages, being a practical hatter, desires to describe intelligibly his calling, dispensing with all technical terms, at the same time conscious of being liable to receive an unfair criticism from his brother tradesmen, although perfectly innocent on their part, resulting from the prejudices engendered by the many would-be secrets that pertain to the different work-shops, together with their various modes and methods of working, all of which most generally are but trifles merely to gain a name. The practice of a trade without a knowledge of the why and the wherefore of certain usages is a sad defect in any workman, but more especially in certain trades : Hatting being one of those which depends upon second causes for its proficiency, we venture here an explana- tion with perfect confidence, hoping that the fraternity of hatters will be indulgent, and that they may pro- fit by an experience of many years in the trade, and that for one error or omission in the writing of 10 these sheets they will find compensation in the new ideas that will spring from their perusal, which may be an incentive to further improvements in the busi- ness resulting beneficially to all. Theory without practice, or practice without theory, is like groping in the dark, and perfection in no trade can be attained till every effect can be traced to its cause, and vice versa. It is much to be regretted that practical operative workmen are so diffident in writing and publishing their experience in their several trades and occupa- tions, quietly permitting theorists ignorant of the business to glean as best they can from other parties the most intricate and complicated particulars of a trade, and hence the attempt to illustrate the most useful branches of an art often results in crude and even erroneous descriptions of things of the greatest moment, and the dissemination as correct, that which is altogether at variance with the truth. In confir- mation of the above, we may instance the manufac- ture of hats as described in a work of much merit, and which is accounted as worthy of all confidence, wherein the error above spoken of is but too plainly visible. Thus, in the supplement to the third edition of that most respectable work the Edinburgh " Encyclo- pedia Britannica," in the article Hat, an apology is made for the original treatise upon that subject, it being acknowledged as both defective and erroneous from the imperfect source of the information. Such a confession, and from such a source, sufficiently ex- onerates any one from egotism in an attempt to write a more perfect and correct description, coupling theory with practice ; relieving the felting process from its misty obscurity by a faithful expose of the whole sys- 11 tern : well knowing that an increase of business, like free trade, will be the result of a right understanding of a formerly supposed mystery, viz., the True cause of Felting. Felt and felted articles being already in use, in many trades in addition to that of hat-making, necessitates a general and indeed a very full and lucid description of the materials of which they are made. Descriptions of Furs, Wools, Hair, &e. Fur, properly speaking, signifies the skins of various species of animals, dressed in alum or some other preparation with the hair on, and made into articles of wearing apparel ; but the term fur also signifies the stuff that is cut from the skin, for the use of the hat- ter, and in this sense alone it will be employed in the following pages. Hair, wool, fur, and animal down are simply slender filaments or thread-like fibres issuing out of the pores of the skins of animals, and all partaking of the same general nature, such as great ductility, flexibility, elasticity, and tenacity, differing entirely from the vegetable wools and downs, such as cotton, &c, which contain neither of these four great characteristics to any valuable or appreciable extent. To characterize in a familiar way these several grades of material, it may be said that fur is distinguished from wool by its greater fineness and softness, and hair from wool by its straightness and stiffness. The nature of all these bearing some relation to each other, it will be necessary in this treatise to use the word hair occasionally to designate one and all of them, that word being most convenient, and tending to avoid confusion. 12 Simple as the idea may be, and though trifling in appearance, yet the study of a single hair is particu- larly interesting, both to the naturalist and the man of business, as will be seen when we mention a few of its many peculiarities ; hoping it will prove a source of enjoyment to the one and a profit to the other. Hair, wool, fur, &c, form quite an extraneous ap- pendage to the skin, or body producing them, not at all directly dependent on the life of the animal for their own existence, for they have been known to live and grow for some time after the death of the animal itself. We also know that they live, grow, and die, showing all the signs of youth, maturity, and old age. Hair possesses no sensation at any period of its ex- istence ; of itself it has no feeling of touch, nor has it the power of voluntary action. The growth of hair is peculiar as it projects and grows in length from the root, and not by the top as with vegetable productions, the lower portion lengthens out, and the top is merely projected forward; and when once cut, it never again resumes its tapering point. Hair or fur of whatever quality, consists of a single slender filament, without a branch or knot of any kind, and that filament is a tube, which is filled with a fat oil, the color of the hair being; derived from this oil. By the chemical analysis of hair it is found to con- sist of nine different substances : 1st, gelatine or animal matter, which constitutes its greater part ; 2d, a white concrete oil in small quantity ; 3d, another oil of a grayish-green color more abundant, these oils com- prising about one-fourth of the entire weight; 4th, a few particles of oxide of manganese; 5th, iron, the state of which in the hair is unknown; 6th, phosphate of lime; 13 7th, carbonate of lime in very small quantity ; 8th, silex in greater abundance; 9th, and lastly, a consider- able amount of sulphur — such is the constitution of all furs, wools, hair, &c, most of which may be dissolved in pure water heated to a temperature above 230° of Fahrenheit, by which it is partially decomposed. Hair is likewise soluble in alkalies, with which it forms soap. Chlorine gas immediately decomposes it, producing a viscid mass. It is worthy of particular remark, that of all animal products, hair is the one least liable to spontaneous change, evidence of which may be found in the fact that the Peruvian, Mexican, and Brazilian mummy hair is still perfect, and is supposed to be from 2500 to 3000 years old, and stands the hygrometric test with equal firmness. From this we should suppose the body or substance of hair and wool to be exceedingly hard and solid, which is really the case, as no pressure has yet been applied sufficiently powerful to entirely deprive wool of the water with which it has been washed — the interstices between the fibres of the assemblage never having been closed by the power applied, as the water therein collected may still be drained off when the pressure is removed. Although hair is of a tubular construction, yet all varieties are not of a completely cylindrical form ; a curl is the result of all flat-sided or oval hairs, the exceeding oval being the unfailing characteristic of the negro race. A cross section of a hair, if circular, denotes the long, soft, and lank fibre of a cold northern animal ; but if the cross section shows an extreme flat-sided hair, that hair will be crisp and frizzled, and of a tropical extraction. Quite a gradual change in the form of the fibre of hair is observed in all animals as 14 we ascend from the equator to the highest latitudes, other things being equal. It has long been a desideratum how to discriminate between the various qualities of htittersfine furs, and no really reliable test has yet been obtained, superior to the judgment of the human eye, the fineness of fibre for the hatter being of most essential importance, par- ticularly that allotted for the flowing nap upon the outside of the hat. Although the thickness of the fibre of the finer furs has never been properly gauged, it will be a source of some satisfaction to know that the diameter of the human hair varies from the 250th to the 600th part of an inch, while the fibre of the coarsest wool is about the 500th and the finest about the 1500th part of an inch. Hair may be bleached on the grass like linen, after previous washing and steeping in a bleaching liquid, after which it may be dyed of any color. It is very doubtful whether the growth of hair can by any artificial means be expedited, or the hair itself increased in length, in quality, or in density. A fine field of enterprise would be opened for the fortunate inventor who could increase the produce of the finer and more expensive furs. In contradistinction to this, however, it may be stated that the inhabitants of some countries, the Malays, for instance, purposely destroy their hair by using quick-lime. We come next to describe minutely another pecu- liarity appertaining to hair, upon which all felting or shrinking of a fabric depends ; that grand secret that has been a mystery in all ages, until within a few years, or at best was only surmised. Upon this property alone depends the whole art of hatting and of felt making, whether in sheets or otherwise, as 15 well as the fulling of cloth and the shrinking of flannels, and all articles the material of which is made of wool, hair, or fur. As many branches of business depend for their suc- cess upon the non-shrinking quality of their goods, a study of the felting principle becomes quite appro- priate and interesting to those manufacturers, whilst perusing that of the opposite. Pulled wools, rather than cut or shorn wools, must always have the pre- ference with the one class of manufacturers; at the same time, the other class must adhere tenaciously to those which have been cut, the roots of the hair caus- ing all the difference, for that remarkable quality, the felting principle, is upon all the same whether pulled or cut. A few familiar facts dependent upon this inherent felting quality of hair will aid the illustration. When a hair is held by the top, it can be severed with a razor much more readily then if held by the root. Again, a hair held by the root, and drawn through between the finger and thumb, feels quite smooth, but when held by the top, a rough and tremulous motion is perceived. Again, place a hair of three or four inches in length by the middle, between the finger and thumb, and twirl it a few times, when the hair will be found to proceed towards one end, as the twirling and rubbing are continued, and invariably advancing root end fore- most, whichever way the hair is placed between the fingers. If two hairs are used in this example, lay the root of the one to the top of the other, their re- spective motions will be doubly discernible. The cause of all these singularities of the hair it is now designed to explain, which shall be done as ex- 16 plicitly and concisely as possible, with a few proofs of its astonishing power in a collective capacity. The above-mentioned phenomena are the result of that same long-hidden property, and which is nothing more than a certain clothing or covering, entirely sur- rounding the stem of every hair, in the form of very minute scales, so very minute, indeed, that it requires the aid of a very powerful microscope to enable the beholder to discern them, and even then but faintly. These scales, which cover thickly every filament of animal hair, wool, fur, &c, are thin pointed lamina, quite similar to the scales on a fish, and overlapping each other as do the shingles or slates upon a house. This state of the hair being understood, the modus operandi of the above examples may be thus explained : When the hair was held by the point, it was easily cut by the edge of the razor entering under the scales; but when held by the root, the instrument slipped smoothly over them ; and the hair that was drawn through the fingers, when held by the point, felt rough and tremu- lous, from the jagged points of the scales, but smooth when drawn in their own direction. The twirling of the hairs between the finger and thumb, resulting in their travelling motion, was on account of the points of the scales catching on the lingers, in the act of rubbing, similar to the heads of wheat or barley at harvest time which school-boys put into the sleeves of their coats, and which are sure to come out at some other extremity to that at which they were put in, caused by the working of the boy's arm upon the jaggy beard or awn of the barley head. The task of counting the number these lamina that clothe the body of these hairs, must have been both tedious and difficult, from their very minuteness and 17 profusion. On a single filament of merino wool, as many as 2400 barbed scales, like teeth, projecting from the centre stem, have been counted in the space of one inch. On Saxony wool there were 2700, while other wools were as low as 1860, and none were found to have so few as 1000 to the inch. No vegetable wools whatever, such as cotton, &c, have any such appendage upon their fibres, and, con- sequently, cotton or cotton goods never shrink in the act of washing, as woollen goods do. Cotton, therefore, never can become a suitable material for felting pur- poses, every fibre being smooth from end to end in either direction, and in contradistinction to fur, which, though equally smooth as the cotton in one way, rebels triumphantly when irritated in the contrary direction, as already described. Mechanically speak- ing, cotton is smooth, solid, and triangular, whilst wool is rough, tubular, and cylindrical. The grand cause of that mysterious and curious operation called felting, fulling, shrinking, thickening, and solidifying of a fabric, whether of original loose wool, fur, or other stuff, or of that spun into yarn and woven into cloth, is the presence of these scales. Till lately, the best operative hatter and the inves- tigating philosopher were equally at a loss to explain upon what principle such effects were produced. Take, for instance, a handful of wet fur or wool, which is merely an assemblage of hairs ; squeeze and press it, work it a little in 'the hand, and then observe the effect; for immediately upon pressing it a certain locomotion is thereby conferred upon every fibre of that assemblage, which is increased by every turn of position that is given to the body of wool. The roll- ing and pressing change the position of each fibre. 18 A friction is produced upon every member composing the mass : a footing as it were is obtained from the scales of each, and the fur or wool being all bent or curled, a progressive motion goes on, interlacing each other in their travels, resulting in a compact, dense body, which may well challenge the goddesses of both patience and perseverance to undo. Every hair has been travelling in its own individual direction, boring, warping, grasping, holding, and twisting amongst its fellows like a collection of live worms. The power of combination, like the fable of the bundle of sticks, is strikingly illustrated in the case of the hair, which when viewed singly seems so very insignificant, but collectively, and when pressed by the hand of oppression, hardship, and ill treatment, they combine and become strong and defiant, clasping each other in their embrace, tenaciously clinging to each other the more they are tortured, as if they were living rational beings, conscious of their inno- cence, and free from guilt. Stockings, for instance, that are knit with soft-spun wool, for the use of whale fishermen in northern lati- tudes, are large enough, when first formed, to hold the whole man, but are felted down to the required size in the falling mill, where they are battered, tossed about, and tortured to that degree that is required by their tormentors. The writer has seen a millful of these stockings whose sides were felted so firmly to- gether, from a neglect of the workmen to turn them in- side out, in due time, during the felting operation, that a knife was required to open them, and which actually failed in several instances, so firmly had their two sides grown together ; common tearing having no effect whatever, each and every single hair had em- 19 braced its neighbors, and their mutual action defied all attempts to open these stockings.* There are instances of ruminating animals having died from the effect of balls of hair having formed within their stomachs, hair by hair having accumulated while licking themselves with their tongues. These balls are all found to be as perfectly felted as the natural bend of the several hairs composing them would allow, the felting having been accomplished by the motions of the intestines of the animals. The disgorged balls from the stomachs of nocturnal fowls are all of the same nature. As has been said, felt may be made of any kind of animal fur, wool, or hair, provided it be bent, crimped, or curled, for if straight as a bristle it would work out of the mass as readily as into it, and lose itself in the operator's hands. All materials intended for felting must be cut from the pelt or skin, and not pulled, for the obvious reason * The most familiar instance of mutual association and combi- nation, resulting in real utility, though not so striking on account of our familiarity with it, is the broad-cloth of which our clothes are made, which when cut by the tailor will never unravel. This result is wholly the effect of its felting in the fulling mill during the operation of scouring and washing, every fibre of the wool of which the cloth is made, having clung to its immediate neighbors, both warp and weft, and with the spirit of true friendship they still remain in each other's embrace, and the cloth is transformed from a loose to a solid fabric. Another instance of the power of combination is the mysteri- ous Gordian knot that we read of in history, which promised the empire of the world to him who could unloose it, and which Alexander the Great is reported to have cut with his sword, because he failed in the attempt. If not a fabulous story, that compound knot the illustrious Gordius is supposed to have cun- ningly felted previous to hanging it up in the temple. 20 that a pulled hair invariably brings with it its root, in the form of a button or bulb, which would greatly impede its progressive motion in the act of working, as each and every hair under the operation of felting bores into and amongst the other filaments of the fur composing the mass, root end foremost, a sharp point therefore is obtained by cutting. This rule is uni- versally and invariably adopted by all hat furriers. Wool of any great length of staple, after being carded, is pressed, and either clipped, cut, or chopped into shorter lengths, which facilitates the felting operation, and improves the solidity of the felt that is produced.* The various materials most used in hat-making are the furs of the beaver, the otter, the rabbit, the hare, a species of the muskrat, a species of the monkey, a species of the seal, and a few others, together with Saxony and Spanish wools and the hair of camels and goats. Numerous as are these various names, most of the animals produce five or six different qualities of stuff, from particular parts of the same skin, varying greatly in price or value. The finest furs all come from those animals that inhabit the coldest climates, and the season of the year in which any of them are killed greatly influ- ences the quality of the fur ; a summer skin of some of these animals being comparatively valueless, how- ever excellent it might be in the winter season. And what is particularly worthy of the hatter's attention * The reason why wool and woollen goods felt and solidify more readily than any straight fibred furs, is owing to the natural curl or friz/le possessed by wool, each and every bend of every individual filament assuming an inclination for travel independent of each other and of the general inclination of the perfect fibre. 21 is, that fur that has been kept one or two years, after being cut from the skin, produces a better working, and a more solid article of felt, than fur from a newly-killed animal. The lamina of such fur seem to rise and erect themselves upon the stem of the hair by being kept, which may account for its better felting quality. This would appear to be confirmed by the well-known fact that the 5 lb. bags in which old fur stuffs have been kept are generally burst open. One or two properties peculiar to furs and wools may still be mentioned, as, for instance, all felting, by whatever means accomplished, necessitates either a damp or wet process with the aid of heat, and the facility of thickening or solidifying is accelerated by the application of soap to the material under the operation. Or the water may be acidulated for the same purpose with a little sulphuric acid, as either of these acts as a penetrating solvent upon the natural oil of the animal which still remains between the stem and lamina or scales of the hair, thus baring the barbed points of the crusty scales, the better to catch and hold their grip upon each other. Oil or grease, on the contrary, when applied directly upon wool, covers up these lamina or scales, thereby destroying their felting power, as is well known to all wool spinners, however little they may understand the real cause of its being so, further than the fact of giving to it a smooth gliding effect, so necessary for the object of their business. It may be amusing, whether true or not, to know that the rude Turcomans are said to dwell, even to this day, in tents covered with felt, which they make by treading with their feet the raw material of which it is made, whilst it lies upon the ground, thus favor- 22 ing the supposition that felting was invented prior to weaving. However, so far as we can learn, a real systematic method of felting is comparatively of a late date, and until within a few years felt has been chiefly employed for hats and hats alone. This is, however, now but a branch of the felt manufacture, for plaids, coats, vests, pants, leggings, shoes, gaiters, slippers, mittens, and caps, the covering of steam cylinders and boilers, carpets, polishing cushions for jewellers and marble cutters, covering for the roofs of houses which is afterwards waterproofed, as also linings of water-tight compartments in ships and ship sheathing, and the covering for the blocks of calico and other printing, &c. &c, are now made of this material. As the nature of hair and the principle upon which its felting pro- perty depends become better known, the manufacture of felt will be stimulated and increased, and applied to many purposes other than those above enumerated, and not imagined at the present time. The high price of the finer furs, resulting from the indiscriminate destruction of the animals which produce them, forms the only apology for the introduction of an inferior material into the body of the manufactured article. Cotton, which is of quite a limber nature, is too pliable, as indeed are all vegetable products when mixed with fur. They lie dead within the body of the mass, and if the labor be continued beyond a cer- tain time, the active principle of the fur will be seen to have clung to itself, leaving the cotton quite ex- posed on the outside. Even under the most perfect manipulation, a mixture of cotton, from its want of elasticity, will give a product which is to a correspond- ing degree deteriorated. 23 There was a time when beaver skins were bought from the natives, by the Hudson Bay Company, at the regular price of 14 skins for a gun, 7 for a pistol, 2 for a shirt or one pair of stockings, 1 for a comb, or twelve needles, &c. &c, less than the hundredth part of their real value, and all the other fur-bearing skins belonging to that country were rated by that of the beaver. "The Scientific American" of New York for Dec. 1859 says that, not much more than half a century ago, not a pound of fine wool was raised in the United States, in Great Britian, or in any other country except Spain. In the latter country the flocks were owned exclu- sively by the nobility, or by the Crown. In 1794, a small flock was sent to the Elector of Saxony, as a present from the King of Spain, whence came the en- tire product of Saxony wool now of such immense value. In 1809, during the second invasion of Spain by the French, some of the valuable crown flocks were sold to raise money. The American Consul at Lisbon, Mr. Jarvis, purchased fourteen hundred head, and sent them to this country. A portion of the pure un- mixed merino blood of these flocks is to be found in Vermont at this time. Such was the origin of the immense flocks of fine woolled sheep in the United States. The same authority further adds that the simplest and most easy method of judging of the quality of wools, is, to take a lock from a sheep's back and place it upon an inch rule ; if you can count from 30 to 33 of the spirals or folds in the space of an inch, it equals in quality the finest Saxony wool grown. Of course as the number of spirals to the inch diminishes, the quality of the wool becomes relatively inferior. 24 Cotswold wool, and some other inferior wools, do not measure more than nine spirals to the inch. The Fulling Mill. Having alluded to the fulling mill as a felting machine, it is only necessary to remark here, that it is a rude looking but effective method of condensing a previously formed article. It consists of a trough six or eight feet long, and two feet wide, varying in size according to the kind of goods to be operated on. The bottom is of a semi-circular form, having a radius of five or six feet, with sides rising three or four feet high, a strong solid heading, but no end piece. There is a heavy wooden battering-ram suspended from above, at a height answering to the curve of the trough ; its immense head has a flat face fitting the trough in which it is made to play freely, similar to the pendulum of a clock. The goods are tumbled promiscuously into this trough in front of the ram, with warm water, fuller's earth, and soap, in sufficient quantity to saturate and wash the material, a small stream of water from a boiler being admitted for that purpose. The power of a water-wheel or steam engine draws back the ram out of its perpendicular, to its allotted distance, whence it falls by its own gravitj^, with a momentum that sweeps the goods before it with a fearful crash, upon the solid heading of the trough. On the withdrawal of this enormous hammer for a second onset, the goods roll over, re- suming their quiescent state, but differently disposed, which is no sooner done than back comes the ram, repeating its dashing blows upon its unoffending and unresisting victims in the trough, washing, scouring, 25 and buffeting them about, till they become not only clean, but completely felted. All of our broadcloths have been subjected to its action, in the process of which the hairs of the weft and those of the warp have become mutually entangled, and each with one another, as with hatting in the regular hand process of loose wool or fur felting. Indeed, every hair composing the whole piece of cloth has its individual and independent progressive motions, combining the threads of both warp and weft together to such an extent that these cloths never unravel, and no hemming of a garment is re- quired in the making of our clothes. Twelve hours in the mill will reduce a piece of cloth two-fifths of its breadth and one-third of its length. The progressive travelling motion of the hair re- sulting in the entanglement of the fibres and conse- quent felting and shrinking of the cloth, is further exemplified in the comfortable soft half-dress caps of the British soldiers, and in the bonnets and caps of the Scottish peasantry generally, which have all been first knitted very large with soft spun yarn, and after- wards felted down to the required size in the fulling mill. During the fulling of any and all kinds of goods, they must be frequently taken out of the trough, to be stretched, turned, the folds straightened, and generally inspected. History of Hats and Hatting. The word hat is of Saxon derivation, being the name of a well-known piece of dress worn upon the head by both sexes, but principally by the men, as a 3 26 covering from the hot sun of summer, the cold of win- ter, a defence from the blows of battle, or for fashion. Being the most conspicuous article of dress, and sur- mounting all the rest, it has often been ornamented with showy plumes, and jewels, and with bands of gold, silver, &c. It is generally distinguished from a cap by its having a brim, which a cap has not, al- though there are exceptions even to this rule of dis- tinction, for there are hats that have no brims, and there are also caps that are provided with a margin. Those hats that are made of fur or wool have all been felted, and felt strictly speaking is a fabric manufac- tured by matting the fibres together, without the preliminary operation of either spinning or of weav- ing. We find but little of hat-making recorded in his- tory, and anything relating to hats is extremely mea- gre, although their partial use may be traced back to the time of ancient Greece amongst the Dorian tribes, probably as early as the age of Homer, when they were worn, although only by the better class of citi- zens when on a distant journey. The same custom prevailed among the Athenians, as is evident from some of the equestrian figures in the Elgin Marbles. The Romans used a bonnet or cap at their sacri- fices and festivals, but on a journey the hat with a brim was adopted. In the middle ages the bonnet or cap with a front was in use among the laity, w T hile the ecclesiastics wore hoods, or cowls. Pope Innocent, in the thirteenth century, allowed the cardinals the use of scarlet hats, and about the year 1440, the use of hats by persons on a journey appears to have been introduced into France, and 27 soon after became common in that country, whence probably it spread to the other European States. When Charles VII. of France made his triumph- ant entry into Rouen in 1440, he wore a felted hat. Hatters of the present clay most generously ascribe the honor of the invention of felting, and of its pros- pective introduction to that of hat-making, to the old renowned Monk St. Clement, who when marching at the head of his pilgrim army obtained some sheep's wool to put between the soles of his feet and the san- dals that he wore, which of course became matted into a solid piece. The old gentleman, philosophizing upon this circumstance, promulgated the idea of its future usefulness, and thus it is said arose the syste- matic art of felting and of hat-making. However all this may be, still the invention of felted fabrics for the use of man may have been, as some assert, very ancient and of quite uncertain origin. The simplicity of its make, as compared with that of woven cloth, shows all speculative assertions to be rather uncertain. However obscure the origin may be, we learn that the first authentic accounts of hatters appeared in the middle ages, in Nuremburg in 1360, in France in 1380, in Bavaria in 1401, and in London in 1510. The hatting trade of the United States of America is noticed first in the representations made by the London Board of Trade to the House of Commons in the year 1732, in which they refer to the complaints of the London hatters, regarding the extent to which their particular manufacture was being carried at that time in New York and in the New England States. 28 The Fashions. A look at the fashions and mode of dressing in ancient times causes amusement. So capricious is the fancy of man that nothing is immutable, all is change, and hats have been of all conceivable shapes and colors, and dressed with the most fanciful deco- rations, plumes, jewels, silk-loops, rosettes, badges, gold and silver bands and loops, &c. &c. The crowns and brims having been in all possible styles from the earliest period. It would appear that nothing is left for the present and all coming time, but the revival of what has already been, even to the fantastical peaked crown that rose half a yard above the wearer's head. In the fifteenth century, hats in Great Britain were called vanities, and were all imported, costing twenty, thirty, and forty English shillings apiece, which were large sums of money at that early period. The most extreme broad brims were worn about the year 1700, shortly after which the three-cornered cocked hat came in, and about this time feathers ceased to be worn, the lingering remains being left for the badge of servitude to the gentleman's attendant. Metal bands and loops were only re- garded as proper for naval and military men of honor. It is a singular historical fact that the elegant soft hat of the Spaniard has remained the same from the earliest period to the present day, while among all other civilized nations a transformation in the style of that article has taken place. Comfort in the wear seems to have given place at all times to fancy and the demands of fashion. Queen Elizabeth's patent grant to the hatters of 29 London is still recognized in England, and the 23d of November is the hatters' annual festival, that being St. Clement's day, the patron of the trade. Preparation of Materials. Previous to cutting the fur from the various skins, they must be moistened, straightened, and cleaned ; the projecting long coarse hairs that are interspersed throughout the fur, removed either by pulling, clip- ping, or shearing; those of the rabbit, etc. being pulled, while those of the hare, etc. are clipped. To pull these superfluous hairs by the hand, the person sits with the skin laid over the knee, strapped down to the foot, and with a dull-edged knife in hand, the thumb being covered with a soft shield, the obnoxious guests are dextrously uprooted. If done by machinery, they are pulled out by being nipped between too re- volving slender rollers. The skin is drawn over a sharp-edged board, which causes these hairs to pro- ject, and the rolls placed in the proper position and distance, frees the fur of its deteriorating associates with great facility, without disturbing the fur. Furs intended for body-making undergo a process called carroting or secretage, which is an artificial method of increasing the felting quality of the fur, enabling the hatter to work at a kettle with clean pure water, dispensing with all acids and the like, and using boilers other than those of lead. It is only of late years that carroting has been invented. It is a chemical operation or method of twisting or bending the natural straight-haired furs, and possesses also the property of raising or lifting the points of the scales which clothe the fibres of the fur, thereby facilitating the operation of felting ; 30 while the fur in its original straight state could be used with satisfaction only as an outside flowing nap upon the hat. The method pursued to accomplish this result is, to dissolve 32 parts of quicksilver in 500 parts of common aqua-fortis, and dilute the solution with one half or two-thirds of its bulk of water according to the strength of the acid. The skin having been laid upon a table with the hair uppermost, a stout brush, slightly moistened with the mercurial solution, is passed over the smooth surface of the hairs with strong pressure. This application must be repeated several times in succession, till every part of the fur is equally touched, and till about two-thirds of the length of the hairs are moistened, or a little more should they be rigid. In order to aid this impregnation, the skins are laid together in pairs with the hairy sides in contact, and put in this state into the stove-room, and exposed to a heat in proportion to the weakness of the mercurial solution. The drying should be rapidly effected, as otherwise the concentration of the nitrate of mercury will not produce its effect in causing the retraction and curling of the hairs. No other acid or metallic solution but the above has been found to answer the desired purpose of the hat-maker, although sulphuric acid without the quick- silver has a limited effect when the skins are treated as those above described. For other purposes, such as that of the upholsterer, hair is curled by first boiling and then baking it in an oven ; or it may be spun into ropes and baked, after which it is teased asunder. Preparatory to cutting the fur from the pelt, the skins are dampened and flattened ; they are thus made smooth and ready for the operation, which is per- 31 formed by hand, with knives about two inches long by four wide, having a short upright handle. The skins are held upon a cutting-board, and the pelt kept moistened with water; a sheet of tin is laid upon the skin, pressed down by the left hand, whilst the knife in the right hand, being guided by the edge of the tin, is run rapidly forward and backward across the skin, gradually sliding the tin toward the tail ; by this means the fur is gathered up, and kept in one fleece. The pelts are appropriated to the manufacture of gilder's cement, or will make excellent glue. Machines in the form of revolving shears, similar to those used for dressing cloth, are employed for such skins as are un- even in the pelt, and which cut the pelt from the fur in slender shreds, being quite the reverse of the hand method, which cuts the fur from the pelt. Stiffening and Water-Proofing Materials. There is reason to suppose that when hats were first invented and long subsequently, the quantity of stuff or material weighed out for a single hat was of itself considered sufficient to stand unharmed the drenchings which it was likely to encounter. However, such a hat in the warm season being unpleasant, a lighter body was proposed, to contain some stiffening substance as a substitute, and the attempt proved quite successful. A search was in- stituted for something suitable for the purpose that would harden the hat sufficiently, without increasing the weight, but rather diminish it. In those times chemistry was comparatively un- known, and glue being at hand, our predecessors in the hatting trade commenced the stiffening of their 32 hats with that material, which long continued the only article likely to succeed. Latterly, however, glue has become quite obsolete, having been entirely super- seded by the various gums and resins, which, when pro- perly prepared, enable the manufacturer to put into the market a much superior hat, and one more pleasant to wear, weighing 3 oz. which in former times would have weighed full half a pound. The solubility of glue in water was its defect, and the ultimate cause of its rejection. Our spirited pre- decessors in the business, by a knowledge superior to that of their predecessors, coupled with a devoted spirit and unfailing resolution, after many vexatious trials but little known to our modern workers, succeeded in rendering a hat not only stout, light, and waterproof, but cheaper and more beautiful to look at, ventilated, and altogether pleasanter to wear. Upon a retrospective view, and considering the total of these improvements, we may well excuse the many secrets and partialities existing in the trade, for be- fore any new admixture of stiffening materials or method of applying them, whether before or after dyeing, &c, could be properly proved, many dozens of hats were under way. It required a length of time to enable a proper judgment of the experiment to be pronounced; thus, if unsuccessful, involving the cha- racter of the manufacturer as a tradesman, and his pecuniary affairs at the same time. The result, however, was at last satisfactory, and now there are several methods of stiffening with a water-proof stiff, which possesses all the requisite qualifications. There is no department in the hatting trade of more importance than that of stiffening, as the kind, 33 quality, and quantity of the stiff must be regulated according to the country in which the hats are to be worn. England, for instance, where there is so much moisture in the atmosphere, requires a much harder stiff than we do in America. American manufac- turers finding that shellac possesses every requisite for both stiffening and waterproofing, now for their best hats use that gum only dissolved in alcohol. 20 lbs. orange shellac being dissolved with 5 gal- lons alcohol in a close vessel, cold, attending carefully to stir it up repeatedly to keep it from lumping and sticking to the bottom. The vessel commonly is used in the form of a barrel or some sort of churn. When fully melted the stiff is ready for use by being thinned down to the desired consistency with additional alcohol and put into the hat with a stiff brush. A cheaper, called alkali-stiff, and much used for in- ferior hats, is — 9 lbs. shellac, dissolved with 18 oz. of sal soda in 3 galls, water in a tin vessel. The vessel with the water is set into another contain- ing boiling water, and heated ; the soda is introduced gradually, and is soon dissolved, and the lac is then put in and stirred occasionally for about an hour, by which time the lac will be dissolved. The whole is then left for an hour or two, when it may be taken out and set to cool. It is better if allowed to remain a few days after having been made. When used, it is reduced to the required strength with more water, a hydrometer being employed as a test. The bodies are simply immersed in the liquor, and 34 passed between a pair of rollers one by one, thereby sweeping off the superfluous compound, but leaving them completely saturated. The hats with this stif- fening must be immediately and rapidly dried in the stove. This stiff is rendered the more popular by adding 3 oz. of common salt to the mixture before using it, as the salt neutralizes the soda, and the hats may be blocked immediately after being stiffened, thereby saving time and dispensing with the use of the stove. The two following receipts are given as good and reliable English methods of stiffening hats : — 7 lbs. of orange shellac. 2 lbs. of gum sandarac. 4 ozs. gum mastic. h lb. of amber resin. 1 pint of solution of copal. 1 gallon of alcohol or of wood naphtha. The lac, sandarac, mastic, and resin are dissolved in the spirit, and the solution of copal is added last. This is called spirit proof, and like our own is put into the body with a stiff brush, and, being full} 7 satu- rated, is set to dry. A cheaper stiffening, also like our own called alkali or water stiffening, is — 7 lbs. of common black shellac. 1 lb. amber rosin. 4 ozs. gum thus. 4 ozs. gum mastic. 6 ozs. borax. ? pint solution of copal. The borax is first dissolved in 1 gallon of warm water. This alkaline liquor is now put into a copper pan 35 heated by steam, or it may be set into another vessel containing boiling water, and the shellac, thus, and mastic added. This is allowed to boil for some time, more warm water being added occasionally, until it is of a proper consistence, which is known by a little practice. When the whole of the gums seem dissolved, half a pint of wood naphtha must be introduced, and also the solution of copal, the liquor should be passed through a fine sieve, when it will be perfectly clear and ready for use. This stiffening is used hot with the following preparations. The hat bodies, before they are stiffened, should be steeped in a weak solution of soda, to destroy any acid that may have been left in them. If sulphuric acid has been used in the making of the bodies, after they have been steeped in the alkaline solution they must be perfectly dried in the stove before the stiff- ening is applied. When stiffened and stoved, they should be steeped all night in water to which a small quantity of sul- phuric acid has been added. Tiiis sets the stiffening in the hat body and finishes the process. If the proof is required cheaper, more shellac and rosin may be introduced. The Blowing Machine. In the manufacture of the finest kinds of fur hats, namely, those with a flowing nap, the stuffs of which they are made must be thoroughly refined. The clipping and pulling operations, to which the skins were subjected previous to cutting off the fur, never free the fur entirely of the coarse hairs that are intermixed with the finer ; and to separate the coarse from the fine, the fur, as it came off the skin, is placed 36 under the action of the blowing machine, which consists of a long, close, narrow, wooden box, divided into a number of apartments, the divisions between each of them having an open space at the top or bottom, so that a blast of wind can be propelled through the whole length of the trunk. The fur is put into one of these receptacles at one end, where it is teased and tossed by revolving brushes set in the bottoms of several of them, and a revolving fan is placed at the head. The whole being set in motion by some first power, the blast of wind from the fan seizes the loose thrown up far that is tossed by the revolving breakers and brushes, and the stream of flying fur is transmitted from division to division, along the whole length of the wooden box. In this operation, the fur is graded as it is blown along and deposited gradually in the respective places, lodging in the most regular order, from the one end of the wooden trunk to the other, the dust and dirt falling down below, the heavier portion of fur not being blown to the same distance as that of the finer, which reaches the farther end, where the finest of all is received entirely refined of its impurities. But the cutting and blowing of fur are both independent and distinct branches of busi- ness, although relatively connected with that of hatting, and the various grades of fur are bought by the hatters from the professional hat furriers or their agents. The Manufacture of Hats. Before commencing a detail of the processes of the trade, it will be necessary to bear in mind that hat- ting is universally divided into two great divisions, 37 viz., the making, and the finishing departments, each of which as a matter of course has its subdivisions. With the exception of encyclopaedias which give detached and very abridged descriptions of felt making and of hatting generally, there has been no specific account published in either pamphlet or book- form, so far as the writer is aware, of the manner in which felt hats are made, or of the principle of felt- ing by which they are produced. This is considered by the writer a sufficient induce- ment to illustrate to the best of his ability a principle entirely belonging to natural history, viz., the natural scaly clothing that is upon all hair, and hitherto but little known, and upon which several important branches of business depend. Indeed, it seems almost absurd to think that a hair, puny as it is in itself, bears upon its sides a something of such importance, so very minute as to require the utmost attention with the aid of the best microscopes to be seen at all, and yet upon that something is based the art of felt- ing and of course of hat-making, besides several branches of other trades, some of which have already been mentioned. Hat-making was long considered a business to which machinery never cou.ld be applied, but the inventions of man have at last dispelled this illusion, and machinery is now employed in several of the most important departments of the trade. The reason why this idea obtained such general credence was, first, on account of the close attention requisite, while the hat is under the operation of sizing. Second, the known impossibility of napping or ruffing a hat by any means with machinery, also, the acknowledged failures of several attempts to substi- 38 tute carding for that of bowing, and various futile attempts with the irons in the finishing department. The innovations of machinery, however, have now obtained a sure footing in all large factories, and some of them will come under observation in their proper places. In the mean time we shall confine our observations to the old system, which still prevails in most small factories and all small towns. Our honest forefathers, the manufacturers in former times, would insist upon making hats to wear not for a season, as with us, but for many years, being afraid of damaging the trade to do otherwise, but now a hat for city wear, of scarcely three ounces weight, and lasting two or it may be three months, is quite a common thing. The usual quantity of stuff given out for a regular felt hat, modified of course to a very great extent by the market, we shall suppose to be three ounces of fur. It may or may not be a mixture of different kinds and qualities of stuff previously prepared by carrot- ing, and may or may not be refined by the winnowing machine, which separates the different qualities of fur. These three ounces, however, are sometimes increased by unprincipled men to four and a quarter or four and a half ounces, by the addition of other and cheaper ingredients, which are all laid upon a platform of boards about five feet square, called a hurdle, over which a large bow of about six feet long strung with cat-gut, Fig. 1, is suspended. This bow is held by the left hand of the hatter, and with the right he holds a small piece of wood with a head or knot upon it. Fig. 2, with which he tugs the string of the bow and makes it vibrate upon the stuff, and into it, with 39 great dexterity and with the nicest judgment. This operation has always been considered a beautiful sight Fig. 1. Hat Bow. to a stranger, as the performer goes on plucking the string, and the string playing upon the top of the fur, Bow-Piu. which lies upon the left hand side of the platform. The fur touched by the string is made to fly from one side of the boards to the other with the greatest regu- larity. So nicely is this bowing performed, the stuff flying from the bow-string hair by hair, and flake by flake, that a hat in this loose state may measure several inches in thickness. In this operation, the different materials are tossed about to-and-fro repeatedly, and mixed with a much greater regularity and change of position of the various filaments than if drawn by carding machinery. One half of the intended hat, called a bat, is bowed at a time, and both in nearly a triangular shape, which being gathered up, and pressed with a flat square piece of wicker-work, Fig. 3, and afterwards with a smooth skin or cloth, is pressed and gently rubbed with the hands backward and forward so as to create a friction 40 on the surface fibres, thereby interlacing the outside filaments, by which means the simply safe-lifting of Fig. 3. Tfffl Hat Basket. these two half-solidified portions of the future hat is secured. The one-half being laid upon the other, with a triangular piece of paper or cloth between, they are joined together by overlaping two of the three sides, thereby giving to the intended hat the form and figure of a hollow cone or great bag, but so tender that none but an experienced hatter could handle it. This operation of bowing is the same, with but little variation, whether it be for coarse or fine hats. If wholly of wool, they are now swaddled carefully in an outer cloth, and sprinkled with water, and laid upon a warm plate of metal which sends the steam up through the hat which is to be pressed, and slightly rubbed, sprinkled again, and turned over. Continuing the pressing and rubbing, and by repeat- ing these operations for some time, the motions are transmitted to all the inclosed fibres of wool with an irritating feeling, as it were, exciting their propensity for travelling, till the outer hairs, in their motions, warp themselves with each other and the surface appears skin-like and becomes smooth. 41 During these actions, the hat inside of the cloth must be several times changed in position and kept in proper form, when its swaddling envelope and the paper within which kept the inside open and free may be removed. These operations concluded, the tender hat must now be subjected to a much more laborious operation, where, properly speaking, the grand practical art of felting takes place, where thousands of thousands of filaments are all in active though slow motion, all travelling on their own indi- vidual course, independent of, and at the same time dependent upon, each other for their mutual support, being carefully guided collectively, by the hatter's good judgment. This stage of the operation is a wet one requiring an open boiler surrounded by planks, which slope to- wards the centre, called a battery, Fig. 4, suitable for six or eight men to work at. Each man is provided with a rolling-pin, cloths, brushes, etc. The soft and tender hat is laid upon one of these planks or benches, Fig. 4. Battery for Sizing Hats. wrapped in a damp cloth, and carefully wetted, squeezed, folded, rolled and unrolled, keeping it constantly moistened by dipping it in the hot water of the 42 boiler, folding and unfolding with every variety of crossings, rolling it as a scroll, pressing, shaking, dipping and rolling it again and again, the hatter all the while bending over his work in front of the almost boiling caldron, and surrounded by steam. He labors hard, ever changing the position of the hat under his hands, so as to make it an evenly felted and perfect piece of work, which these oft-repeated motions ultimately accomplish. This is the grand felting operation ; the cause of which was so long considered a mystery, and now ascertained to result from the peculiar natural con- struction of the animal fibre, as already explained. In this planking or sizing of the hat, sometimes with half a dozen under hands at the same time, the envelop- ing cloth is soon thrown aside as the hat grows in solidity. The hands of the hatter are defended from the scalding water by thick leather shields upon the palms, and as the hat approaches its proper size, it is scalded and belabored with determined importu- nity, coiled, rolled, pressed, and pinned, backward and forward till the size of the hat is reduced to nearly half of its original dimensions, and the tension of the several fibres becomes so great that the hat will felt no farther. At this stage it is impossible for it to be torn asunder, and is still in its original form of a hollow cone. Such is the making department of the trade, the felting process, where a firm piece of cloth (for such is the body of a hat) is manufactured from loose wool or fur, independent of either spinning or weav- ing. We have now explained the making of the bare 43 body, as it is called, of a plain hat, in as concise a manner as the subject will permit. There are yet a variety of qualities and kinds of hats requiring a variation more or less in the mani- pulation of the article, so as to suit a fanciful and fastidious people. For instance, the quantity and quality of fur, or an entire change of materials, pro- duce quite a different appearance both in the look, the wear, and the price of the hat, while the form of the cone must be changed to admit of a high or low crown, or of a broad or narrow brim, &c. &c. All felt hats, of whatever texture, nature, or name, must have undergone the above described operations, and many have to go back a second time to the plank kettle, and there undergo an additional teasing and ducking in the scalding water. For instance, all those destined to receive a coat of fur upon the outside finer than that of which the body is made, and con- stituting the flowing nap of the hat, which is merely a kind of veneering or outside plating, which will shorly be described. A very good hat is made having a flowing nap that is raised directly from the body itself. Thus when the body of such a hat as has been described is about half wrought up at the kettle, it undergoes in another department the operation of shaving, by which means the projecting coarse hairs are all cut off, after which, on being returned to the kettle, the hatter, with his stiff brush, card, and comb, raises a nap upon the half solidified body, which is constantly im- proved as he continues to manipulate with the brush. The hat is, at the same time, reduced in its dimen- sions by the operation of felting until at the conclusion when it appears of the desired size, fully felted, and 44 adorned on the outside with its rough and flowing nap, which otherwise would have been smooth and clothlike. This is called the brush hat. Shaving. In the process of fur felting there is a constant ten- dency for the strong straight hairs of the body to work to the outside, so that whether the hat is de- signed to receive a bare finish afterwards, or to set a plated cover of beaver for a nap, those bodies must, all undergo the operation of shaving. A workman sits in another apartment with one of them, when dry, spread over his knee, and with a long bladed sharp knife in hand, sweeps rapidly over the surface, cutting off and depriving it of those deteriorating superfluous intruders, after which the hats are forwarded to the stiffening department. Stiffening Process. The bodies of the hats now made, dried and shaved, and the spirit water-proofing already prepared, being thinned, or reduced to the proper consistence, the hat is laid upon a flat sloping board, and the stiffening is put into it with a stout brush, and soaked to that de- gree of saturation known only by experience, the brims receiving a double portion for extra stoutness, and are then set aside to dry. The alkali or inferior kind of stiffening, when used, is likewise diluted, and applied by immersing the body fully into the prepared ingredients already described, and either wrung out with the hands, or passed a couple of times between a pair of rollers set at a pro- per width, which determines the quantity of proofing absorbed by the hat. 45 It should be observed, regarding this stiffening of hats, that it is simply a varnishing of the several fi- bres of the fur of which the hat is made, each hair individually has got a coat of waterproofing varnish, for when dry it will be found that the interstices between each and every fibre are quite open and free, and therefore susceptible of ventilation ; thus differing entirely from what would have been the case had it been stiffened with any kind of paste. Ruffing or Napping. Very little of this is done at present in the United States. After the bare body of the hat is stiffened, if a flowing nap of beaver, otter, neutra, or other fine fur is desired, finer than that of which the body is made, half an ounce more or less of the superior uncarroted stuff is weighed out, sufficient to cover the whole out- side surface of the hat. The hatter lays this precious morsel with perhaps one-eighth ounce of cotton on the hurdle, under the bow, as he did with the stuff for the body, and with a similar but lighter instrument, these two stuffs are completely mixed and spread upon the boards, as evenly as his experienced hands can do it ; the cotton being used merely to enable him to handle the far, which otherwise would be so thinly spread, and so attenuated of itself, as to endanger the simple act of lifting it. This mixture of fur and cotton is next spread upon the wet bare body of the hat as it lies upon the plank at the kettle, a little water is sprinkled over it and beat down with a brush. The hat with this surface covering is wrapped very care- fully in a piece of cloth or coarse hair-cloth, and ope- rated on very lightly, and nearly in the same manner as when felting the body. The object to be attained 46 is to get the fibres of the fine fur to penetrate the body, and take root as it were therein — great care and watchfulness being demanded of the workman at every motion of his hands, in this manner of working. The points of the fibres of the beaver fur penetrate the body of the hat, and having once got a footing, it con- stantly advances, as the active careful rolling, folding and unfolding, shaking and tossing go on, until the fur has separated itself from the cotton ; by its bor- ing, having obtained a firm lodgment in the solid felt of the hat body root end foremost. The cotton with which it was mixed is left behind loose and useless, for want of the little rough scaly property that the other possessed. An inexperienced workman in thus ruffing a hat is liable to continue his work too long, until the beaver napping has burrowed quite through to the inside of the hat, where it is lost.* In the various operations of the hatter with hot water, whether in body-making, napping, or dyeing, &c, the water should not be allowed to boil, for independent of the damage to some kinds of stiffening, as hair contains a large portion of gelatine in its sub- stance (to which alone it owes its suppleness and tough- ness), this gelatine will be separated from the hair. This is particularly the case with napped hats, for when thus treated the fibre becomes much more * Hatters' kettles for fur hatting are made of copper, as they take less firing than those that are made of lead. But lead must be the metal if sulphuric acid, no matter in how small quantity, is used in the water. It is generally resorted to by the men in sizing wool hats, as it facilitates the felting operation. This acid (vitriol), having no affinity for lead, does not affect the kettle, while it would soon eat the one of copper through. Care, however, must be taken that no stone be let fall into the water of the lead kettle, for a hole will soon result from such an accident. 47 brittle than before, and the nap soon breaks off round the square. Fur hats having a flowing nap are sometimes clip- ped very short with revolving shears similar to those used in dressing cloth, and which is done previous to blocking or dyeing. Fig. 5. Hat Block. Blocking. Previous to dyeing, all hats must be blocked, using such blocks as approach the intended shape of the hat, and as soon as possible after the making department is concluded. It is a laborious operation, though sim- ple, as the nature of felt allows it to be stretched to a great extent in any direction when it is wet and hot. In the act of blocking, the conical form of the hat is lost for the first time. The hat is now immersed in the hotting water of the kettle, and while wet and hot the tip is stretched wide, and the whole thing simply drawn down over the block, a tight cord is run down to where the band is to be and the brim flattened out. Dyeing. The next operation is that of dyeing or coloring, and if convenient, and the hats fine, each hat should be upon its respective block when in the color kettle* 48 great care being observed to keep the square from abrasion, as the least rub may deprive a napped hat of its fur at that exposed and important part. Most generally, however, the hats are colored without a block, the blocking being performed as soon after the dyeing and washing as possible in boiling water. The ordinary ingredients for black are, for 12 dozen, 144 lbs. of logwood, chipped, or its value in extract. 12 lbs. of green sulphate of iron or copperas. 7h lbs. of French verdigris. The kettle should never boil nor exceed 190 degrees, and during the operation the hats must be repeatedly taken out and exposed to the action of the oxygen of the air, so as to strike a deeper color, and during the necessary exposure to these airings, the time is im- proved by having two suits of hats going on at the same time. From six to twelve hours are required to complete the operation. The shorter the time the hats are in the dye, compatible with the deepness of the color, the better will be the goods, as boiling extracts the gelatine of the hair and makes the nap brittle, which is seen by comparing dyed articles with those that are of a native color. Pumicing or Pouncing. Pouncing is a term for rubbing down the outside of a hat with a piece of pumice stone, sand paper, or emery paper, whereby the hat is made entirely bare, smooth, and fine, resembling a piece of very fine cloth. These are generally called cassimere hats. This operation is usually performed after dyeing, and previous to finishing. Some makers, however, pre- fer to singe the hats instead of pouncing, but such 49 hats never feel so fine as the others, as the singing of any hair invariably produces a hard crisp burnt knob upon the end. Finishing.* When a hat arrives at that state of forwardness ready for finishing, it is a very unsightly object to any person but a hatter. Most of its processes have been wet ones, but now it is to assume a genteel and prepossessing appearance, under the artistic appli- ances of brushes, cloths, hot irons, and labored ex- ercise. If a plain soft hat, it is pulled over such a Fig. 6. Hat Iron. block as is required, a cord is run round the hat to keep it tight upon the block; the tip and brim are then flattened with the hot iron, wet sponge, brushes, and hair-cloth cushion or velure, several wettings being necessary in finishing. The brim is next cut to the required width, and the cord run down to the depth of the block. The * As every hat must be finished upon a block of some particular form, upon which the bat assumes the exact counterpart, it becomes necessary with those having broad tops, that the block be in five separate pieces, so as to get them out or into the hat, the centre piece acting as a wedge to the whole. 50 side-crown is now to be finished, along with the tip and upper and under sides of the brim, the hatter exercising his best judgment. The block is then withdrawn, the brim curled and set, and the finished hat sent off to the trimmer to get lined and bound ; it is then tipped off* and packed for market. The finishing of this kind of hat is a simple opera- tion when compared to that of a napped hat ; requir- ing only the assuming of the proper shape and form, the solidifying of the body, and giving it such a lustre and finish as the quality of the material will allow. The stiff cassimere hat being less flexible, is sub- jected to hot steam preparatory to blocking, whereby it is made soft and pliable. When in this state it is drawn down over the block, and the block withdrawn, to insert a prepared disk of pasteboard into the crown for strength, after which it is finished much in the same way as that already described, but with the dif- ference, that a cloth must always intervene between the hot iron and the hat when finishing. The finishing of a napped hat, whether it be brush or beaver, is a very different process from that for either of those just described, requiring the nicest attention and patient perseverance by the best workmen. The hats are given out by the half dozen, which are sorted for the different sizes and steamed one by one ; the hot steam softens the stiffen- ing, and when pliable, the hat is drawn down over the respective finishing blocks, the nap of each hat straightened with a wet brush, and a half finish given to it with the water, brush, and bare hot iron. The block is then withdrawn and the hat given to be shaved with a razor. This seems a singular operation ; 51 but a few passes with that instrument over the hat effectually cut off all those projecting coarse hairs that have eluded all previous attempts at removal, and without in the smallest degree endangering the finer fur of the nap. The hat is now returned to the finisher to complete the process. These coarse hairs, when left in the hat depreciating very materially its value, were formerly plucked out by hand with a pair of pickers, hair by hair, often to the injury of the hat. The advantage of the razor will be obvious to all. A pasteboard disk, well spread with dissolved shellac, is now inserted into the tip, and the block reset. The workman with his hot iron, wet and dry brushes, &c, lays down the nap in its proper direc- tion, and the hat by continuous labor becomes solidi- fied and more elastic, the tip is rendered stout by the adhesion of the prepared inside disk ; and by the repeated wettings, and careful ironings and brush- ings, all the ripply appearance of the fur is destroyed, and the whole surface becomes smooth and shining. The crown being finished is then papered up, and the same operations that were bestowed upon the crown are now to be repeated on the brim, both on the upper and under side, which having been accom- plished, a gauge is applied and the brim cut to the required width ready for the trimming. There is a beautiful invention for preserving the form of all hats having flat or soft supple brims by means of a flattened wire, upon which two small twists are made, and when joined as a hoop, the proper concave is produced. This hoop is attached to the outer edge of the brim, and covered with the binding, and thus the unsightly slouch that often 52 deformed, particularly the soft brimmed hat, is per- manently prevented, and the graceful curve com- pletely secured. Silk Hatting. The art of silk hatting is comparatively of modern invention, consisting simply of a cover of silk plush over a body of some other material. As much sleight of hand is required in this department, it naturally follows that a good workman is a valuable and appre- ciated artisan. The bodies used for this kind of hat have been so various, that a full, or even succinct, description of them would be quite superfluous. Wool and fur bodies, straw and leghorn, cork, whalebone and muslin, &c, even stretchers similar to umbrellas with- out a body at all have been adopted, and all of them have had their day. At present, however, the trade seems to have settled down to the two kinds — fur and muslin. The fur body of a silk hat, called a shell previous to coming into the hands of the silk finisher, is made much in the same manner as that of a plain soft hat, by felting and sizing it down to the proper dimen- sions in the plank kettle. It is quite light and thin, and when blocked or otherwise, and dried, is then ready for stiffening by the finisher. The different substances for this purpose, and the various methods of doing it, have been as numerous as the varieties of bodies that have been adopted. The whole of them, however, now have been abandoned for shellac. The most simple and the best stiffening for any hat is shellac dissolved in alcohol, and thinned down to 53 a proper consistence. A cheaper, however, and at the same time good stiffening, is the ammonia stiff already described. Either of these is applied in a like manner and with the like operations. The soft body or shell, as it is often called, is immersed in the liquid in a basin, then wrung out and pulled upon a block, the brim being flattened, a brush is dipped into another ves el containing a thicker lac, and applied to the square and brim for extra strength ; after this the block is withdrawn, and the body set to dry. These felted bodies or shells, as they are called, when dry are steamed generally over the hatter's hot iron, and pulled when warm and soft over the finish- ing block. A cord is then run tight round the shell, and the block withdrawn ; the prepared pasteboard tip is inserted into the crown, and the block reset; after which the body receives a regular hot ironing all over. In this operation the inserted tip adheres to the felt, and the whole body assumes the exact counterpart of the block, both crown and brim. The rough hairs are now to be removed by sand or emery paper and the block withdrawn. The body next receives a coat of the best size, and when dry two coats of seed-lac, or copal varnish which finishes the making of this kind of body. Those bodies that are made of muslin, when first invented, were called gossamer, from their extreme lightness, and though they have increased in weight, they still retain the name of gossamer hats. In preparing for the body, a few yards of muslin are extended upon a frame, and saturated with lique- fied shellac, or water stiff, which when dry is cut bias into strips for sides, tips, and brims. One side of these side and tip pieces of muslin is overlaid with 54 the silk intended for the inside lining of the hat, and pressed to adhesion ; or this may be done while in the web before being cut into strips. The block being set upon the bottom-board, one of these extra pre- pared sides is wound tight round the side-crown of it, and the two ends stuck together by overlapping. A piece of the prepared tips is next laid on, and made to adhere to the side-crown. The brim consists of three thicknesses of stout mus- lin of a circular form, each with a hole in the centre, all of which are slipped over the crown down to their place of destination with a quarter of an inch of the edge rising up on the side. A second side-crown and another tip are now applied, covering the others, and the whole of these cemented together with the hot iron, the shellac with which they were stiffened acting as a cement. After receiving a coat of size and one of varnish, this body will be ready, like the other fur body, for the finisher. In prepar- ing these bodies, cover the block with a soft shell. Before commencing the finishing, however, we will describe the sewing of the silk plush cover, which is quite a nice and particular piece of work. The strip of plush for the side-crown is cut from the web bias and of a width the depth of the intended hat ; the tip piece which is to mate this side-crown is of course circular, and a quarter of an inch larger all round than the tip of the hat. These two pieces are to be sewed together by hand face to face, the edges being folded back, and the plush put well through to the proper side with the needle as the sewers proceed, so that the seam when the hat is finished may not appear bare for want of plush. In finishing, whether the hat body be of fur or 55 gossamer, the first thing is the putting on of the un- der brim, which we shall suppose to be plush, satin, or merino. A strip is cut from the web or piece at about an angle of forty-five degrees, and having the length reduced to suit the size of the hat ; the two ends are then sewed together, and having been laid on the hat, one of the edges is made fast to the edge of the brim with the iron, all round, and smoothly laid down, the bias allowing this to be done by stretching. It is next to be steamed with a damp cloth under the hot iron and the inner edge stuck inside of the hat with the nose of the iron. The upper brim is next in order. A strip of silk plush the requisite width is run on, slightly, in much the same manner as with the under brim, but dis- pensing with both the cloth-steaming and often with the sewing. The one end of this upper brim being cut with the scissors and the other with the knife, a good invisible seam may be made. The brims being now on, the tip of the hat is wetted inside, and the block put in. The silk plush cover, having been previously spread with gum tragacanth, about where the side seam is likely to be, and now dry, is carefully drawn over the crown and fitted to the hat ; the two ends of the cover being folded back and marked for the seam. The cover is then removed, the plush brushed back at the folding, and the cloth cut for the seam with a pair of sharp scis- sors ; the top of the seam is cleaned or dressed off and the cover replaced on the hat body. The tip and side crown are now to be stuck with the hot iron to the body with particular care, so as to make a good joining at the seam, and not to draw through the 56 varnish. The making of a good seam is the test of a good workman. The dressing and polishing of the hat now com- mence; and while it remains upon the block, this is done by means of brushes, wettings, ironings, etc., once, twice, or three times in succession, after which it is fixed on the veluring machine where it is re- volved rapidly, for the purpose of freeing the nap of all impurities by means of the hair-cloth velures that are applied. The hat is next taken back to the bench, where it receives its final dry -ironing, veluring, etc., and the crown is papered up. The brim is yet to be finished, which is done by hand, with the brushes, sponge, iron, etc., and made to shine like the crown ; after this it is given to the trimmer to be trimmed and bound, when it comes back to be curled and properly shaped in the brim, suiting the taste of the wearer. The workman who gives the hat its final touches makes use of a number of tools, which, though of seemingly trifling appear- ance, are nevertheless necessary for his department, which requires a refined taste. Forming Machines. Such is hat-making, but we cannot conclude with- out remarking that there have been many patents granted in this and other countries for improvements in hatting, that we cannot notice. Nevertheless there are two, of decided merit, claiming attention, as having entirely revolutionized one-half of the making department, and which may be modified and extended to answer many purposes, in addition to that of hat-makinsx. 07 0q" 58 The first and most ingenious is called the pneu- matic process of forming the bodies, hence in all large cities the bowing operation is not employed. It is as follows : A cone of sheet copper punched full of small holes, and set upright, revolves slowly upon its axis ; beneath this or attached to it an exhausting fan is placed, causing by its rotation a current of air to draw through the holes from the outside. A trunk or box with an opening facing against this revolv- ing cone, discharges the fur which is fed into it at the other end by a feeding apron, in quantity just sufficient for one hat-body. It is drawn into this trunk between two rollers that are covered with leather or felt, and immediately seized by a cylinder revolving about four hundred times in a minute, fur- nished with a number of stiff brushes. This gene- rates a current of air which scatters the fur and blows it out of the mouth of the trunk, where floating in the air it is speedily drawn upon the perforated cone, and evenly spread over the top and sides of the same, in quantity enough for one hat-body in so many revolu- tions. The discharging trunk is so adjusted that any desired quantity of fur can be deposited on any parti- cular portion of the cone. When the cone has got the fur for one hat-body, the workman wraps over it a wet cloth and slips a metallic cover over the whole, which he removes into a tank of hot water. A new cone is immediately set in its place to receive another coating of fur. The hot water into which it has been dipped tends to make the mat more tenacious, which is next slipped off the cone, taken to a table, gently worked by hand-rolling in a piece of blanket, squeezed and pressed, and folded into a convenient shape and 59 sent to the regular hatter to be felted at the ordinary plank kettle. The cost of hat-bodies is reduced, it is computed, by this process as five or six to one of the old bowing system, and the rapidity of production is as thirty to one. It will not have escaped observation that this inge- nious piece of machinery is applicable only for fur, the filaments of which are short and less inclined to tangle than those of wool, but another and no less useful piece of mechanism has been invented for forming the bodies of wool hats, and like the other has entirely superseded the use of the bow in all lame factories where wool hats are made. It consists of a modified common carding machine, the sliver from which is conducted to a set of double conical blocks that are placed base to base, and which slowly revolve upon their axes in front of the carding machine, and the sliver is received and wound upon these combined blocks to the required thickness, Fig. 8. Forming Machine for Wool Hat Bodies. sufficient for one hat, both blocks being covered at the same time. This machine which carries the blocks has a horizontal vibratory motion, or swaying backwards and forwards, that enables the sliver to 60 be wound in a systematic manner on the cones, with a varied thickness of material for brims and crowns, and causing also the fibres of the wool to lie in a diagonal position, as layer upon layer covers the blocks. The bodies of the two hats, each of a coni- cal figure, are thus made over the surface of a double cone which are separated by cutting them along their middle or base line, and slipping them off at the end. They are now ready to be wetted, shrunk, and felted in the usual manner by the regular hatter. Shoes and Gaiters of Felt. We will here describe the making of felted gaiters and shoes, which is similar to the art of hatting. There may be other and better methods, as the ex- pansive stretching nature of felt may admit of other modes. The wearer of these gaiters may walk upon the slippery pavement with comfort and full confidence, and if furnished with a leather or rubber under-sole, they are a neat, easy, comfortable cover for the feet. A given quantity of wool calculated for one pair of shoes is weighed out, which is divided into four equal portions, two of them for each shoe. One at a time is laid upon the hurdle, and with the proper bow it is bowed as if for a hat, and disposed of in exactly an equilateral triangle, which being gathered together with the basket, is pressed, and temporarily solidified, laid aside, and the other portion treated in the same manner. A piece of coarse brown paper is now folded into a triangular shape, a little smaller than the bats just bowed ; all the three edges are to be folded together with the paper inclosed. The use of the inclosed paper is to prevent the inner surfaces from felting to- 61 gether, and to keep the inside open. The intended shoe is next lapped in a sheet of cloth, and hardened at the hot basin (the basin is a disk of solid iron with a fire beneath). Water sprinkled on the sheet when turned upon the basin, sends steam all through the mass, and when rubbed slightly by hand, friction is communicated to the surface fibres, which in a short time become smooth, when the position of the trian- gular wool should be changed and the rubbing con- tinued. A few crossings and rubbings give it a con- sistence sufficient for handling at the plank kettle, where we shall suppose both shoes to have arrived. The felting operation at the kettle is performed in quite the same manner as that of a hat, by pressing, rolling, folding, and unfolding, &c, with its dippings into the hot water, until the material has assumed a hardness and solidity quite astonishing to the casual observer. This operation finished, the shoe still in the trian- gular shape, one corner is now to be cut off to make an opening, and the confined paper taken out, which is quite a soggy spongy lump of pulp. The mate to this shoe having been advanced to the same forwardness, they are to be pulled upon their respective lasts and dried, and perhaps dyed, after which they are pounced, and finally trimmed. Printers' Sheets. The making of sheet felt for calico and other printers is a business that fell into the hands of the hatters at the introduction of the waterproofing of hats, as pre- vious to that time the thick stout old hats of former times were quite sufficiently thick for the fittings of their blocks, so that when no more of them could be 5* 62 gotten, recourse was had to the new article, although it should be at a slight sacrifice. Felt is employed in this business because of the fa- cility with which it lifts and carries from the color sieve, the colors that are to be applied to the cloth. Wood and Copper blocks or rollers require two diffe- rent thicknesses of felt, and though various qualities are made, a solid body and clear smooth surface and edge when cut and pounced by the block-cutter, are absolutely necessary, as otherwise, a ragged edge to the printed figures on the cloth will be the result. The following makes a very good article: — 7 ozs. best backs of coney wool, and 6 ozs. of Saxony lamb's wool. The coney is first well broken over with a light bow, upon the hurdle, and then by means of the heavier wool bow, the well-carded Saxony is intimately mixed with it. This thoroughly accomplished, the whole is to be divided into two portions ; the one a little heavier than the other, which is laid upon the hurdle, and with the same wool bow, strung with stouter cat-gut, the hat- ter disposes of the mixture in a perfectly even flat form, of an oblong square, which when gathered by the hatter's basket, measures 18 inches wide by 3 feet long. A cloth is then spread over it, and the whole turned upside down ; the sides and ends of the cloth are lapped over, so that this bat as it is called is com- pletely enveloped. A stiff skin is now thrown over it, and pressed and rubbed for some time in an even manner, to reduce its thickness. The skin having been removed, the sheet with its bat is rolled and pressed still more, then laid aside while the other half undergoes exactly the same operation, but is made three inches shorter in length. 63 These two sheets, which are destined to form but one, are connected thus. The shorter is first folded over upon itself, and the two ends joined by overlap- ping with a proper inlayer of paper ; then the larger bat is laid upon this one, and the whole turned upside down, so that the joinings of the two bats will be upon opposite sides of the sheet of felt. After these joinings are carefully made, the would-be sheet ap- pears exactly like a lady's muff, and is again to be enveloped in the cloth, for the hardening process, at the hot basin, where it receives a partial steanling, rubbing, re-folding, &c, till finally it is carried to the plank kettle, where the severest labor must be applied ; the object being to condense the materials of which it is made to the utmost degree of tension. It is then cut open, dried, and receives an application of a weak solution of size ; when again dry it is well pounced with pumice stone, and the edges cut straight, which finishes a first class printers' sheet of felt, the size being 33 or 33i inches long by 12 inches wide. Sheets for copper blocks or rollers require a thickness of a quar- ter of an inch, and those for wood three-sixteenths of an inch. Some prefer a sheet altogether of Saxony wool. Cloth Hats. After the introduction of gutta-percha into the arts, and the manufacture of it into thin sheeting, a new kind of hat was introduced, made of gutta-percha cloth, and from the variety of shades, &c. seemed for some time to supersede the soft low-crowned felt article. But the cupidity of some of the manufacturers destroyed the business almost entirely when in its infancy, some say purposely, by making them so very 64 inferior and at the same time so perfect a counterfeit, that the really good and perfectly made hat became universally distrusted, and hence the result. We shall refrain from all notice of the methods em- ployed tending to this deterioration of the new article, and merely describe the making of the honest, sound, and valid hat, the revival or resuscitation of which is well worthy of consideration. A dry, thin, and soft fur or wool body is to be drawn upon the proper block, generally 3 or 4 inches deep with either a square or round crown, and the brim spread out upon the bench or bottom board. A cir- cular piece of gutta-percha gum the size of the in- tended brim, having its centre cut out, is to be slip- ped over the crown down on to the felt brim ; a similar piece of good cloth is likewise slipped over in the same manner to cover the gum, and now the extreme outer edges of the felt and cloth are to be carefully cemented together by means of the gum, bypassing round a hot iron. The usual' stirrup or bridle is then thrown over the hat, girding the inner edge of the cloth to the block, and stuck with the heel of the iron. This partially stuck brim is finally overlaid with a wet loose brim-cloth and properly ironed, the heat of the steam from the damp cloth softens the gutta-percha gum and effects the adhesion of the cloth to the fur body. About half an inch of cloth will project up on the side crown, which is also made to adhere to the felt body by the heated iron. The block is now to be withdrawn, and the hat turned inside out, which reverses this would-be upper brim to the under side. The hat is next to be re- blocked, a repetition of the gum and cloth is to be applied to this side of the brim exactly as with the 65 other, and then succeeds the covering of the crown, which is to be wholly laid over first with the gutta- percha and then with the previously prepared cloth cover as a crown piece, these being held tight by means of the blocking-cord. The whole crown, both tip and sides, is to be cemented and finished, never omitting the wet finishing-cloth between the hat and the hot iron, and the hat is now complete and ready for lining and trimming. The above makes a good soft pliable cloth hat. But if a stifier and firmer hat is wanted of the same material, the felt body is to be put through the pro- cess of the alkaline bath, similar to that of fur hats, and when dry, proceeded with as above. Another method of making these cloth hats is to dispense with the fur body entirely, the block being covered with two thicknesses of cloth and having a ply of gutta-percha gum between, which are cemented together by steaming and pressing, using at all times a wet cloth under the hot iron. The brim is separate and distinct from the crown when made, and consists of a piece of thick wool padding, which is to be covered on both sides with the proper cloth, cemented together with the gum, first one side and then the other, after which the crown and brim are sewed to- gether. In all these cases, the gutta-percha gum acts not only as a cement but also a water-proofing to the hat. Conclusion. In this treatise upon the history of hats and hat- making, of furs, wools, &c, and the manufacture of felt, we are well aware of the impossibility of illustrat- ing in full the hatting trade of America, as this coun- 66 try stands alone as compared with others, on account of the mixed population that is here collected. As we have representatives in this, as in every other line of business, from every civilized nation upon earth, with all their various methods of working in their own ac- customed ways, the prejudices naturally engendered and entertained through habit being hard to combat, so that the judges of this work may be numerous and various, and no doubt profusely severe in some of their criticisms. But there is going on a rapid amalgamation of all that is best in the trade of hatting, resulting from the continued flow of immigration, and heightened greatly by the wanderings of hatters generally, from shop to shop, and from town to town, that must ultimately bring together in this our beloved land, a perfection in the trade that cannot be attained by any other nation.
