Chapter III: Part 3

29. On this galley, the lines are accumulated in long columns, which are afterwards divided into pages, and tied together with a string, to prevent the types from falling asunder, or into _pi_, as the printers term it. A sufficient number of pages having been completed to constitute a _form_, or, in other words, to fill one side of a sheet of printing-paper, they are arranged on an _imposing-stone_, and strongly locked up, or wedged together, in an iron _chase_.

30. The first impression taken from the types is called the _proof_. This is carefully read over by the author or proof-reader, or both, and the errors and corrections plainly marked in the margin. These corrections having been made by the compositor, the form is again locked up, and delivered to the pressman.

31. The pressman having dampened his paper with water, and put every part of his press in order, takes impressions in the following manner: he places the sheet upon the _tympan_, and confines it there by turning down upon it the _frisket_; he then brings them both, together with the paper, upon the form, which has been previously inked. He next turns a crank with his left hand, and thereby places the form directly under the _platen_, which is immediately brought, in a perpendicular direction, upon the types, by means of a lever pulled with his right hand.

32. After the impression has been thus communicated, the form is returned to its former position, and the printed sheet is removed. The operation just described, is repeated for each side of every sheet of the edition. In the cut at the head of this article, the pressman is represented as in the act of turning down the frisket upon the tympan. The business of the boy behind the press is to apply the ink to the types by means of the _rollers_ before him. In offices where much printing is executed, the roller-boy is now dispensed with, simple machinery, attached to the crank of the press, called a _patent roller-boy_, being substituted in his place.

33. Within the present century, great improvements have been made in the printing business generally, especially in the presses, and in the means of applying the ink. In the old _Ramage_ press, the power was derived from a screw which was moved by a lever; but, in those by several late inventors, from an accumulation of levers.

34. In 1814, printing by machinery was commenced in London, and rollers became necessary for inking the forms. These were made of molasses, glue, and tar, in proportions to suit the temperature of the weather. From these originated composition balls in the following year, and in 1819, hand rollers. Formerly the ink was applied by means of pelt balls stuffed with wool.

35. The power-press first used in this country, was invented, in 1823, by Mr. Treadwell, a scientific mechanic, of Boston, who was originally a watch-maker by trade. It acts on the same principle with the hand press, and is equal to three of these of the best construction. Daniel Fanshaw, who first applied steam to printing in the United States, introduced several of these presses into New-York, in 1826. Messrs. Adams and Tufts, of Boston, have each invented a power-press which act on the same principle with Mr. Treadwell's.

36. The presses noticed in the preceding paragraph, are used chiefly in printing books and periodicals requiring moderate speed in their production. But they do not answer the purposes of the daily press in large cities, where from twenty thousand to sixty thousand impressions of a single paper are required every day. To supply this immense demand of the public was the original aim of the inventors of power-presses in England. The first attempt to construct a printing machine was made, in 1790, by William Nicholson, of London; but his machine was never brought into use. The next attempt was made by Mr. Konig, an ingenious German, who but partially succeeded. The first really useful machine was constructed by Messrs. Applegate and Cowper.

37. The machines used in this country are modifications of that originally invented by Mr. Napier, of England. The paper is brought in contact with the form of types by means of a cylinder, while the form is passing underneath it. The press is constructed with one or two cylinders. A double cylinder press will give from 4000 to 6000 impressions an hour. The improvements on this press were made by Robert Hoe & Co., who have permitted Mr. Napier to introduce them into his press in England.

THE TYPE-FOUNDER.

1. The types cast by the type-founder are oblong square pieces of metal, each having, on one end of it, a letter or character, in relief. The metal of which these important instruments are composed, is commonly an alloy consisting principally of lead and antimony, in the proportion of about five parts of the former to one of the latter. This alloy melts at a low temperature, and receives and retains with accuracy the shape of the mould. Several hundred pounds of type-metal are prepared at a time, and cast into bars filled with notches, that they may be easily broken into pieces, when about to be applied to use.

2. In making types, the letter or character is first formed, by means of gravers and other tools, on the end of a steel punch. With this instrument, a _matrix_ is formed, by driving it into a piece of copper of suitable size. A punch and matrix are required for every character used in printing. A metallic mould for the body of the type is also made; and, that the workman may handle it without burning his hands, it is surrounded with a portion of wood. The mould is composed of two parts, which can be closed and separated with the greatest facility.

3. The type-metal is prepared for immediate use by melting it, as fast as it may be needed, in a small crucible, over a coal fire. The caster having placed the matrix in the bottom of the mould, commences the operation of casting by pouring the metal into the mould with a small ladle. This he performs with his right hand, while with the other he throws up the mould with a sudden jerk; then, with both hands he opens it, and throws out the type. All these movements are performed with such rapidity, that an expert hand can cast about fifty types of a common size in a minute. Some machines have been lately introduced, which operate with still greater rapidity.

4. Each type, when thrown from the mould, has attached to it a superfluous portion of metal, called a _jet_, which is afterwards broken off by hand. The jets are again cast into the pot, or crucible, and the types are carried to another room, where the two broad sides are rubbed on a grindstone. They are next arranged on flat sticks about three feet long, and delivered to the _dresser_, who scrapes the two sides not before made smooth on the grindstone, cuts a groove on the end opposite the letter, and rejects from the row the types which may be defective.

5. The whole process is completed by setting up the types in a printer's composing-stick, and tying them up with packthread. Much of the work in the type-foundry is performed by boys and females. In the preceding cut are represented a man casting types at a furnace, and a boy breaking off the jets; also two females rubbing types on a large grindstone. The fumes arising from melted lead in the casting-room are considered deleterious to health.

6. Various sizes of the same kind of letter are extensively used, of which the following are most employed in printing books--Pica, Small Pica, Long Primer, Bourgeois, Brevier, Minion, Nonpareil, Pearl, and Diamond. A full assortment of any particular size is called a _fount_, which may consist of any amount, from five pounds to five hundred, or more. The master type-founder usually supplies the printer with all the materials of his art, embracing not only types, leads, brass rules, and ordinary ornaments, but also cases, composing-sticks, galleys, printing-presses, and other articles too numerous to be mentioned.

7. The inventor of the art of casting types was Peter Shoeffer, first servant or workman employed by Guttemburg and Faust. He privately cut a matrix for each letter of the alphabet, and cast a quantity of the types. Having shown the products of his ingenuity to Faust, the latter was so much delighted with the contrivance, that he made him a partner in the printing business, and gave him his only daughter, Christina, in marriage.

8. The character first employed was a rude old Gothic, mixed with secretary, designed on purpose to imitate the hand-writing of those times, and the first used in England were of this kind. To these succeeded what is termed _old English_, or _black letter_, which is still occasionally applied to some purposes; but Roman letter is now the national character not only of England, but of France, Spain, Portugal, and Italy. In Germany, and in the states surrounding the Baltic, letters are used which owe their foundation to the Gothic, although works are occasionally printed for the learned in Roman.

9. The Roman letter owes its origin to the nation whence it derives its name, although the faces of the present and ancient Roman letters differ materially, on account of the improvements which they have undergone at various times. For the invention of the Italic character, we are indebted to Aldus Manutius, who set up a printing-office in Venice, in 1496, where he also introduced Roman types of a neater cut.

10. Before the American revolution, type-founding was carried on at Germantown, Pennsylvania, by Christopher Sower, at Boston by Mr. Michelson, and in Connecticut by Mr. Buel; but there was too little demand for types, to afford these enterprising individuals much patronage. Soon after the close of the revolution, John Baine established a foundery in Philadelphia. The printers, however, were not supplied with every necessary material and implement of the art from American founderies, until 1796, when Messrs. Binny & Ronaldson commenced the business in the same city. Baine and Ronaldson were both from Edinburgh, Scotland. The first type-foundery was established in New-York, in 1809, by Robert Lothian, a Scotch clergyman, and father of the ingenious type-founder, George B. Lothian.

11. In the year 1827, William M. Johnson, of New-York, invented the machine for casting types now used by John T. White, and in 1838, David Bruce, Junr., produced another, which was purchased by George Bruce. George B. Lothian has also lately invented a machine for the same purpose, and likewise one for reducing types to an equal thickness. Both of these machines act with great accuracy. There are now in the United States sixteen type-founderies; viz., two in Boston, six in New-York, three in Philadelphia, one in Baltimore, one in Pittsburg, one in Cincinnati, one in Louisville, and one in St. Louis.

THE STEREOTYPER.

1. The word _stereotype_ is derived from two Greek words--_stereos_, solid, and _tupos_, a type. It is applied to pages of types in a single piece, which have been cast in moulds formed on common printing types or wood-cuts. They are composed of lead and antimony, in the proportion of about six parts of the former to one of the latter. Sometimes a little tin is added.

2. The types are _set up_ by _compositors_, as usual in printing, and _imposed_, or locked up, one or several pages together, in an iron _chase_ of a suitable size. Having been sent to the _casting-room_, the types are slightly oiled, and surrounded with a frame of brass or type-metal. They are then covered with a thin mixture of finely pulverized plaster and water. In about ten minutes, the plaster becomes hard enough to be removed.

3. The mould, thus formed, having been baked in an oven, is placed in an iron pan of an oblong shape, and sunk into a kettle of the melted composition above mentioned, which is admitted at the four corners of the cover to the cavities of the mould beneath. The pan is then raised from the kettle, and placed over water. When the metal has become cool, the contents of the pan are removed, and the plaster is broken and washed from the plate.

4. As fast as the pages are cast, they are sent to the _finishing-room_. Here they are first planed on the back with a machine, for the purpose of making them level and of an equal thickness. The letters are then examined, and, when deficient, are rendered perfect by little steel instruments called _picks_. Corrections and alterations are made by cutting out original lines, and inserting common printing types, or lines stereotyped for the purpose. The types are cut off close to the back with pincers, and fastened to the place with solder. The plates, when they are finished, are about one-sixth of an inch in thickness.

5. When all the pages of a work have been completed, they are packed in boxes, which are marked with certain letters of the alphabet, to indicate the form or pages which they contain. While the pages are applied in printing, they are fastened to blocks of solid wood, which, with the plates, are intended to be the same in height with common types.

6. The first stereotype plates were cast by J. Van der Mey, a Dutchman, who resided at Leyden about the year 1700. A quarto and folio Bible, and two or three small works, were printed from pages of his casting; but at his death, the art appears to have been lost, although the plates of these two Bibles are still extant, the former at Leyden, and the latter at Amsterdam.

7. In 1725, William Ged, of Edinburgh, without knowing what had been done in Holland by Van der Mey, began to make stereotype plates. But being unable to prosecute the business alone for want of funds, he united in partnership with three others. One of the partners being a type-founder, supposing that success in the enterprise would injure his business, employed men to compose and print the proposed works in a manner that he thought most likely to spoil them.

8. Accordingly, the compositors, while correcting one error in the proof, made intentionally several more; and the pressmen battered the letter, while printing the books. By these dishonest and malicious proceedings, the useful enterprise of Mr. Ged was defeated. He, however, afterwards printed, in an accurate manner, two or three works. The first of these was a Sallust, the pages of which were set up by his son, James Ged, who was but an apprentice to the printing-business. This part of the work was performed in the night, when the workmen were absent from the office.

9. After the death of Mr. Ged, no attention was paid to the art, and a knowledge of it was lost at the decease of his son, which took place, about the year 1771: but it was a third time invented by Alexander Tilloch, Esq., who, in conjunction with Mr. Foulis, printer to the University of Glasgow, made many experiments, until plates were produced yielding impressions which could not be distinguished from those of the types from which they had been cast. But owing to circumstances unconnected with the real utility of the art, the business was not prosecuted to a great extent.

10. About the year 1804, the art was again revived by the late Earl Stanhope, assisted by Mr. A. Wilson, a printer, who turned his whole attention that way. In their efforts to complete the invention, they were assisted by Messrs. Tilloch and Foulis; and, although they succeeded after many experiments, they were strenuously opposed in their efforts to introduce the practice, the printers supposing, perhaps with some reason, that it would prove injurious to their business.

11. This useful art was introduced into the United States by J. Watts, an Englishman from London, who had acquired a knowledge of the process from A. Wilson. He entered into a partnership with Joseph D. Fay and Pierre C. Van Wyck, Esquires. They first stereotyped the Westminster Catechism, which was printed by J. Watts & Co., for Messrs. Whiting & Watson, in 1813. They also stereotyped a New Testament. But the business proving to be unproductive, Fay and Van Wyck retired from the concern. Watts afterwards stereotyped about one third of an octavo Bible. The moulding of all the plates produced in Watts's foundery was executed by Mrs. Watts. On the 21st of March, 1815, Watts sold all his plates, together with his materials and knowledge of the process, to B. S. and J. B. Collins, for $6500. The Messrs. Collins afterwards carried on the business successfully.

12. In 1812, David Bruce went to England for the express purpose of obtaining a knowledge of the art, as it was kept a profound secret by Watts; and having learned the method of one Nicholson, of Liverpool, and having also acquired some knowledge of Earl Stanhope's plan, he returned to New-York, and commenced stereotyping, in conjunction with his brother, George Bruce, in the year 1813. They soon completed two setts of 12mo plates for the New Testament, one of which they sold to Matthew Carey, Nov. 8, 1814. Soon afterwards, they finished the whole Bible. David Bruce invented the machine for planing the plates, in 1815.

THE PAPER-MAKER, AND THE BOOKBINDER.

THE PAPER-MAKER.

1. The materials on which writing was executed, in the early days of the art, were the leaves and bark of trees and plants, stones, bricks, sheets of lead, copper, and brass, as well as plates of ivory, wooden tablets, and cotton and linen cloth.

2. The instruments with which writing was practised were adapted to the substance on which it was to be formed. The _stylus_, which the Romans employed in writing on metallic tablets covered with wax, was made of iron, acute at one end, for forming the letters, and flat or round at the other, for erasing what may have been erroneously written.

3. For writing with ink, the _calamus_, a kind of reed, sharpened at the point, and split like our pens was used. Some of the Eastern nations still write with bamboos and canes. The Chinese inscribe their characters with small brushes similar to camel's hair pencils. We have no certain evidence of the application of _quills_ to this purpose until the seventh century.

4. As the literature of antiquity advanced, a material adapted to works of magnitude became necessary, and this was found both in the skins of animals, and in the celebrated plant papyrus, of Egypt; but the time when they were first applied to this purpose cannot be determined, although it is probable that the former has the preference as regards priority.

5. The papyrus was an aquatic plant, which grew upon the banks of the Nile. In the manufacture of paper from this reed, it was divested of its outer covering, and the internal layers, or laminæ, were separated with the point of a needle or knife. These layers were spread parallel to each other on a table, in sufficient numbers to form a sheet; a second layer was then laid with the strips crossing those of the first at right angles; and the whole having been moistened with water, was subjected to pressure between metallic surfaces. The pressure, aided by a glutinous substance in the plant, caused the several pieces to become one uniform sheet.

6. Parchment was manufactured from the skins of sheep and goats. In the preparation, these were first steeped in water impregnated with lime, and afterwards stretched upon frames, and reduced by scraping with sharp instruments. They were finished by the application of chalk, and by rubbing them with pumice-stone. The skins of very young calves, dressed in a similar manner, was called vellum. Parchment and vellum are still used for deeds and other important documents.

7. When Attalus, about 200 years before Christ, was about to found a library at Pergamus, which should rival that of Alexandria, one of the Ptolemies, then king of Egypt, jealous of his success, prohibited the exportation of papyrus; but the spirited inhabitants of Pergamus manufactured parchment as a substitute, and formed their library principally of manuscripts on this material. From this fact, it received the name of _Pergamena_ among the Romans, who gave it also the appellation of _Membrana_.

8. The greatest quantity of paper was manufactured at Alexandria, and the commerce in this article greatly increased the wealth of that city. In the fifth century, paper was rendered very dear by taxation; and this probably was an inducement for an effort to produce a substitute. Accordingly, in the eighth century, it began to be superseded by cotton paper, although it continued in use in some parts of Europe, until three hundred years after the period last mentioned.

9. The manufacture of cotton paper was introduced into Spain, in the eleventh century, by the Arabians, who became acquainted with it in Bucharia as early as A.D. 704. About the year 1300, it was commenced in Italy, France, and Germany; and, in some of the paper-mills of these countries, paper was made from cotton rags. Linen paper is thought to have originated in Germany, about the year 1318.

10. The first paper-mill in England was erected by a German, named Spillman, in 1588; but no paper, except the coarse brown sorts, was made in that country, until about the year 1690. The finer kinds, both for writing and printing, were, before that time, imported from the Continent. But the paper of English manufacture will now compare with that of any other country. The French also make very fine paper.

11. In the United States, this manufacture has rapidly increased in amount within a few years. According to an estimate made in 1829, it appears that the whole annual product of the mills is worth between five and seven millions of dollars, and that the rags collected in this country amount to about two millions. The number of hands employed in the business are ten or eleven thousand, of whom about one-half were females. The manufacture has since been considerably increased, although the number of operatives may have been diminished, on account of the introduction of improved machinery.

12. Nature has supplied us with a great variety of substances from which paper may be fabricated, as flax, hemp, cotton, straw, grass, and the bark of several kinds of trees; but the fibres of the three first productions, in the form of rags, are the most usual materials. Most of these are primarily purchased from the people at large, by retail booksellers, country merchants, and pedlers, who in turn dispose of them to persons called rag-merchants, or directly to the paper-makers. When the rags come from the original collectors, all kinds are mixed together; but they are assorted according to their color and the nature of their original fibre, either by the rag-merchants, or by the paper-makers themselves.

13. In our attempts to afford the reader an idea of this manufacture in general, letter-paper has been selected, as affording the best means of illustration; since for this kind of paper, the best stock is employed, and the greatest skill is exerted in every stage of the process.

14. The process of the manufacture is commenced by cutting the rags into small pieces, by the aid of a sharp instrument, commonly a piece of a scythe, which is placed in a position nearly perpendicular before the operator. In the reduction of very coarse rags, such as sail-cloth, a cutting machine is also employed. Then, with the view of sifting out the loose particles of dirt, the rags are deposited in a large octagonal sieve made of coarse wire, and placed in a close box in a horizontal position. The sieve is moved by machinery, like the bolt of a flour-mill.

15. The second stage of the process consists chiefly in the reduction of the rags to a _pulp_. This is effected by the action of a cutting machine, the essential parts of which are two sets of blunt knives, the one stationary, and the other revolving. The machine is placed in a large elliptical tub, in which the rags are also deposited, with a suitable quantity of water. The liquid and fibrous contents of the tub are kept moving in a circle by the action of the machine, through which it passes at one point of its revolution.

16. The maceration occupies from ten to twenty hours, according as the material is more or less rigid; and, during part of this time, water is permitted to run in at one side of the tub, and out at the other, to render the pulp perfectly clean. Towards the close of this process, the pulp, if necessary, is bleached by means of chloride of lime, and oil of vitriol. It is also sometimes colored by adding a quantity of dye-stuff. The bleaching and coloring are effected without interrupting the action of the machine. The rags having been thus reduced, the pulp, together with a suitable quantity of water, is let out into a reservoir, from which it is drawn off into a _vat_, as fast as it may be needed for the production of the paper.

17. With this vat is connected the paper-making machine; and the part of the latter which first comes in contact with the material is a hollow cylinder, surrounded with a fine web of wire-cloth. This cylinder being immersed in the contents of the vat more than one-half of its diameter, the water passes off with a uniform rapidity, and the fibrous particles which had been suspended in it, settle with a remarkable uniformity on the outside of the brazen web. As the cylinder revolves, a continued sheet is produced, which is taken up by an endless web of woollen cloth, and carried round another cylinder of equal diameter, and then between two more, by which it is partially pressed.

18. From between these rollers, the paper passes out, in a continued sheet, upon a large cylindrical reel, called the _lay-boy_; and when a certain quantity of it, which is determined by a gauge, has been accumulated, the lay-boy is removed to a low table. The paper is then cut, with a toothless handsaw, into sheets twice the size of letter-paper. This part of the operation is very quickly performed, as a workman can cut up and pile in heaps, to be pressed, twenty reams in half that number of minutes, and attend to the machine at the same time.

19. After the paper has been successively pressed, and handled by separating the sheets two or three times, it is hung up on small poles, in an airy room, to be dried; and having been again pressed, it is sized by holding a quantity of the sheets at a time in a thin solution of glue and alum, the former of which is prepared in the paper-mill for the purpose, from shreds and parings of raw hides. The paper is freed from superfluous portions of the size, by submitting it to the action of a press. It is again dried as before, and again pressed; after which, the several sheets are examined, and freed from lumps and other extraneous substances.

20. They are then severed in half with a cutting machine, and afterwards calendered, by passing the sheets successively between rollers; or they are pressed between smooth pasteboards. In the latter case, hot metallic plates are sometimes interposed between every few quires of the sheets. The paper, when treated in this way, is called hot-pressed. It is next counted off into half-quires, put up into reams, pressed, trimmed, and finally enveloped in two thick sheets of paper, which completes the whole process of the manufacture.

21. The manufacture of paper, as just described, seems to be a tedious process; yet with two machines and a suitable number of hands, say sixty or eighty, three hundred reams of letter-paper can be produced from the raw material in a single day. It is hardly necessary to remark, that paper is of various qualities, from the finest bank-note paper, down to the coarsest kinds employed in wrapping up merchandise, and that, for every quality, suitable materials are chosen. The process of the manufacture is varied, of course, to suit the materials. None but writing and drawing paper requires to be sized.

22. Until after the beginning of the present century, paper was made exclusively _by hand_, and this method is still continued in a majority of the mills in the United States, although it is rapidly going out of use. It differs from that just described chiefly in the manner of collecting the pulp to form the paper, this being effected by means of a _mould_, a frame of wood with a fine wire bottom, of the size of the proposed sheet. In the use of this instrument, a quantity of the pulp is taken up, and while the _vatman_, or _dipper_, holds it in a horizontal position, and gives it a gentle shaking, the water runs out through the interstices of the wire, and leaves the fibrous particles upon the mould in the form of a sheet. The sheets thus produced are pressed between felts, and afterwards treated as if they had been formed by means of a machine.

23. The first idea of forming paper in a continued sheet originated in France; but a machine for this purpose is said to have been first made completely successful in England, by Henry and Sealy Fourdrinier. Many machines made after their model, as well as those of a different construction, are in use in the United States, to some of which is attached an apparatus for drying, sizing, and pressing the paper, as well as for cutting it to the proper size. Very few machines, however, yield paper equal in firmness and tenacity to that produced by hand.

THE BOOKBINDER.

1. Bookbinding is the art of arranging the pages of a book in proper order, and confining them there by means of thread, glue, paste, pasteboard, and leather.

2. This art is probably as ancient as that of writing books; for, whatever may have been the substance on which the work was executed, some method of uniting the parts was absolutely necessary. The earliest method with which we are acquainted, is that of gluing the sheets together, and rolling them upon small cylinders. This mode is still practised in some countries. It is also everywhere used by the Jews, so far as relates to one copy of their law deposited in each of their synagogues.

3. The name Egyptian is applied to this kind of binding, and this would seem to indicate the place of its origin. Each volume had two rollers, so that the continued sheet could be wound from one to the other at pleasure. The square, or present form of binding, is also of great antiquity, as it is supposed to have been invented at Pergamus, about 200 years before Christ, by King Attalus, who, with his son Eumenes, established the famous library in that city.

4. The first process of binding books consists in folding the sheets according to the paging. This is done by the aid of an ivory knife, called a _folder_; and the operator is guided in the correct performance of the work by certain letters called _signatures_, placed at the bottom of the page, at regular intervals through the book.

5. Piles of the folded sheets are then placed on a long table in the order of their signatures, and gathered, one from each pile, for every book. They are next beaten on a stone, or passed between steel rollers, to render them smooth and solid. The latter method has been introduced within a few years. This operation certainly increases the intrinsic value of the book; but it is not employed in every case, since it is attended with some additional expense, and since it diminishes the thickness of the book, and consequently its value in the estimation of the public at large.

6. The sheets, having been properly pressed, are next sewed together upon little cords, which, in this application, are called _bands_. During the operation these are stretched in a perpendicular direction, at suitable distances from each other, as exhibited in the foregoing cut. The folded sheets are usually notched on the back by means of a saw, and at these points they are brought in juxta-position with the bands. After the pages of several volumes have been accumulated, the bands are severed between each book. The folding, gathering, and sewing, are usually performed by females.

7. At this stage of the process, the books are received by the men or boys, who generally _take on_ one hundred at a time. The workman first spreads some glue on the backs of each book with a brush. He then places them, one after the other, between boards of solid wood, and beats them on the back with a hammer. By this means the back is rounded, and a groove formed on each side for the admission of one edge of the pasteboards.

8. These having been applied, and partially fastened by means of the bands, which had been left long for the purpose, the books are pressed, and the leaves of which they are composed are trimmed with an instrument called a _plough_. The pasteboards are also cut to the proper size by the same means, or with a huge pair of shears. In the preceding picture, a workman is represented at work with the plough. The edges are next sprinkled with some kind of coloring matter, or covered with gold leaf. A strip of paper is then glued on the back, and a _head-band_ put upon each end.

9. The book is now ready to be covered. This is done either with calf, sheep, or goat skin, or some kind of paper or muslin; but, whatever the material may be, it is cut into pieces to suit the size of the book; and, having been smeared on one side with paste, if paper or leather, or with glue, if muslin, it is drawn over the outsides of the pasteboards, and doubled in upon the inside.

10. The covers, if calf or sheep skin, are next sprinkled or marbled. The first operation is performed by dipping the brush in a kind of dye, made for the purpose, and beating it with one hand over a stick held in the other; the second is performed in the same manner, with the difference that they are sprinkled first with water, and then with the coloring matter.

11. After a small piece of morocco has been pasted on the back, on which the title is to be printed in gold leaf, and one of the waste leaves has been pasted down on the inside of each of the covers, the books are pressed for the last time. They are then glazed by applying the white of an egg with a sponge.

12. The books are now ready for the reception of the ornaments, which consist chiefly of letters and other figures in gold leaf. In executing this part of the process, the workman cuts the gold into suitable strips or squares on a cushion.

13. These are laid upon the books by means of a piece of raw cotton, and afterwards impressed with types moderately heated over a charcoal fire; or the strips of gold are taken up, and laid upon the proper place with instruments called _stamps_ and _rolls_, which have on them figures in relief. The portion of the leaf not impressed with the figures on the tools, is easily removed with a silk rag. The books are finished by applying to the covers the white of an egg, and rubbing them with a heated steel _polisher_.

14. The process of binding books, as just described, is varied, of course, in some particulars, to suit the different kinds of binding and finish. A book stitched together like a common almanac, is called a pamphlet. Those which are covered on the back and sides with leather, are said to be _full-bound_; and those which have their backs covered with leather, and the sides with paper, _half-bound_.

15. The different sizes of books are expressed by terms indicative of the number of pages printed on one side of a sheet of paper; thus, when two pages are printed on one side, the book is termed a folio; four pages, a quarto; eight pages, an octavo; twelve pages, a duodecimo; eighteen pages, an octodecimo. All of these terms, except the first, are abridged by prefixing a figure or figures to the last syllable: thus, 4to for quarto, 8vo for octavo, 12mo for duodecimo, &c.

16. The manufacture of account-books, and other blank or _stationary_ work, constitutes an extensive branch of the bookbinder's business. It is not necessary, however, to be particular in noticing it, as the general process is similar to that of common bookbinding. Those binders who devote much attention to this branch of the trade, have a machine by which paper is ruled to suit any method of keeping books, or any other pattern which may be desired.

THE BOOKSELLER.

1. The book-trade has arisen from small beginnings to its present magnitude and importance. Before the invention of typography, it was carried on by the aid of transcribers; and the booksellers of Greece, Rome, and Alexandria, during the flourishing state of their literature, kept a large number of manuscript copyists in constant employ. Among the Romans, the transcribers or copyists were chiefly slaves, who were very valuable to their owners, on account of their capacity for this employment.

2. In the middle ages, when learning was chiefly confined to the precincts of monastic institutions, the monks employed much of their time in copying the ancient classics and other works; and this labor was often imposed upon them as a penance for the commission of sin. From this cause, and from an ignorance of the true meaning of the author, much of their copying was inaccurately performed, so that great pains have been since required in the correction of the manuscripts of those times.

3. This mode of multiplying copies of books was exceedingly slow, and, withal, so very expensive, that learning was confined almost exclusively to people of rank, and the lower orders were only rescued from total ignorance by the reflected light of their superiors. For a long time, during the reign of comparative barbarism in Europe, books were so scarce, that a present of a single copy to a religious house was thought to be so valuable a gift, that it entitled the donor to the prayers of the community, which were considered efficacious in procuring for him eternal salvation.

4. After the establishment of the universities of Paris and Bologna, there were dealers in books, called _stationarii_, who loaned single manuscripts at high prices; and, in the former place, no person, after the year 1432, could deal in books in any way, without permission from the university, by which officers were appointed to examine the manuscripts, and fix the price for which they might be sold or hired out.

5. For a long time after the invention of printing, the printers sold their own publications; and, in doing this, especially at some distance from their establishments, they were aided by those who had formerly been employed as copyists. Some of these travelling agents, at length, became stationary, and procured the publication of works on their own account.

6. The first bookseller who purchased manuscripts from the authors, and caused them to be printed without owning a press himself, was John Otto, of Nuremburg. He commenced this mode of doing business, in 1516. In 1545, there were, for the first time, two such booksellers in Leipsic. The great mart for the sale of their books was Frankfort on the Maine, where were held three extensive fairs every year. Leipsic, however, soon became, and still continues, the centre of the German book-trade.

7. The first Leipsic catalogue of books appeared as early as the year 1600; but the fairs at that place did not become important, as regards the book-trade, until 1667, when it was attended by nineteen foreign booksellers. The booksellers of Germany, as well as some from distant countries, meet at the semi-annual fairs held in that city, to dispose of books, and to settle their accounts with each other. Every German publisher has also an agent there, who receives his publications, and sends them, according as they are ordered, to any part of Germany.

8. In no other part of the world, has such a connexion of booksellers been formed, although almost every kingdom of Europe has some city or cities in which this branch of trade is chiefly concentrated; as London, in England; Edinburgh, in Scotland; and Amsterdam, Utrecht, Leyden, and Haerlem, in the Netherlands. In Spain and Portugal, the price of every book is regulated by the government.

9. A very convenient method of effecting the sale and exchange of books among booksellers, has been adopted in the United States; and this is by auction. A sale of this kind is held in Boston once, and in New-York and Philadelphia twice, every year; and none are invited to attend it but the _trade_; hence such sales are denominated _trade-sales_.

10. The sale is usually conducted by an auctioneer who has been selected by a committee of the trade in the city in which it is to be held. In order to obtain a sufficient amount of stock for the purpose, the agent issues proposals, in which he informs publishers and others concerned in this branch of business, of his intention, and solicits invoices of books, to be sold at the time specified. A catalogue of all the books thus sent for sale, is distributed among the booksellers.

11. The booksellers having assembled, the books which may have been accumulated from different parts of the Union, are offered in convenient lots, and _struck off_ to the highest bidder. Each purchaser holds in his hand the printed catalogue, on the broad margin of which he marks, if he sees fit, the prices at which the books have been sold; and the record thus kept affords a tolerable means of determining their value, for a considerable time afterwards.

12. A sale of this kind occupies from four to six days; and, at the close of it, a settlement takes place, in which the parties are governed by the terms previously published. The payments are made in cash, or by notes at four or six months, according to the amount which the purchaser may have bought out of one invoice. The conductors of the sale are allowed about five per cent. commission for their services.

13. A vast number of books is also sold, every year, at auction, to miscellaneous collections of people, not only in the cities and considerable towns, but likewise in the villages throughout the country. By many booksellers, this method of sale is thought to be injurious to the trade, since it has reduced the prices of books, and interfered with the regular method of doing business. These disadvantages, however, have been far overbalanced by the increased number of readers which has been thus created.

14. The circulation of books is likewise promoted by means of travelling agents, who either sell them at once, or obtain subscriptions for them with the view to their future delivery. These methods have been employed more or less from the very commencement of the printing business; and they have probably contributed more to the general extension of knowledge than the sale of books by stationary booksellers. In fact, they are among the most prominent causes of the vast trade in books, which is now carried on, especially in the United States.

15. Nevertheless, publishers, who do not employ agents to vend their books, generally consider them interlopers upon their business; and the people themselves, who owe a great share of their intellectual cultivation to this useful class of men, are generally averse to afford them the necessary patronage, because they require a small advance on the city prices to pay travelling expenses.

16. A considerable amount of books is also sold by merchants who reside at some distance from the cities and large towns. They, however, seldom venture to purchase those which have not been well known and approved in their neighborhood; and, in a majority of cases, regard them as mere subjects of merchandise, without taking into consideration the effects most likely to be produced by these silent, but powerful agents, when circulated among their customers.

17. Some booksellers in Europe confine their trade chiefly to particular departments; such as law, theology, and medicine. Others deal in toy-books, and books of education, or in rare and scarce books. This is the case, to a limited extent, in the United States, although our booksellers commonly keep an assortment of miscellaneous publications, as well as various articles in the stationary line; such as paper, quills, inkstands, and blank work.

THE ARCHITECT.

1. Architecture, in the general sense of the word, is the art of planning and erecting buildings of all kinds, whether of a public or private nature; and it embraces within its operations a variety of employments, at the head of which must be placed the Architect. Architecture is of several kinds, such as _civil_, _naval_, _military_, and _aquatic_; but it is the first only that we propose to notice in the present article.

2. The construction of buildings as means of shelter from the weather, appears to have been among the earliest inventions; and, from the skill exhibited in the construction of the ark, we have reason to believe that architecture had been brought to considerable perfection before the deluge. This opinion is also supported by the fact stated in holy writ, that the descendants of Noah, not more than one hundred years after the great catastrophe just mentioned, attempted to build a city and a lofty tower with bricks burned in the fire. This project could never have been thought of, had they not been influenced by the knowledge of former centuries.

3. The confusion of the language of the people caused their dispersion into different parts of the earth; and, in their several locations, they adopted that method of constructing their dwellings, which the climate required, and the materials at hand admitted; but, whatever the primitive structure may have been, it was continued, in its general features, from age to age, by the more refined and opulent inhabitants; hence the different styles of building, which have been continued, with various modifications, to the present day.

4. The essential elementary parts of a building are those which contribute to its support, inclosure, and covering; and of these the most important are the foundation, the column, the wall, the lintel, the arch, the vault, the dome, and the roof. Ornamental and refined architecture is one of the fine arts; nevertheless, every part of an edifice must appear to have utility for its object, and show the purpose for which it has been designed.

5. The _foundation_ is usually a stone wall, on which the superstructure of the building rests. The most solid basis on which it is placed is rock, or gravel which has never been disturbed; next to these are clay and sand. In loose or muddy situations, it is always unsafe to build, unless a solid basis can be artificially produced. This is often done by means of timber placed in a horizontal position, or by driving wooden piles perpendicularly into the earth; on a foundation of the latter description, the greater part of the city of Amsterdam has been built.

6. The _column_, or _pillar_, is the simplest member of a building, although it is not essential to all. It is not employed for the purpose of inclosure, but as a support to some part of the superstructure, and the principal force which it has to resist is that of perpendicular pressure. The column is more frequently employed in public than in private buildings.

7. The _wall_ may be considered the lateral continuation of the column, answering the purposes both of support and inclosure. It is constructed of various materials, but chiefly of brick, stone, and marble, with a suitable proportion of mortar or cement. Walls are also made of wood, by first erecting a frame of timber and then covering it with boards; but these are more perishable materials, which require to be defended from the decomposing influence of the atmosphere, by paint or some other substance.

8. The _lintel_ is a beam extending in a right line from one column or wall to another over a vacant space. The _floor_ is a lateral continuation or connexion of beams, by means of a covering of planks. The strength of the lintel, and, in fact, every other elementary part of a building used as a support, can be mathematically determined by the skilful architect.

9. The _arch_ answers the same purpose as the lintel, although it far exceeds it in strength. It is composed of several pieces of a wedge-like form, and the joints formed by the contact of flat surfaces point to a common centre. While the workmen are constructing the arch, the materials are supported by a _centring_ of the shape of its internal surface. The upper stone of an arch is called the _key-stone_. The supports of an arch are called _abutments_; and a continuation of arches, an _arcade_.

10. The _vault_ is the lateral continuation of an arch, and bears the same relation to it that a wall bears to a column. The construction of a simple vault is the same with that of an arch, and it distributes its pressure equally along the walls or abutments. A complex or groined vault is made by the intersection of two of the common kind. The groined vault is much used in Gothic architecture.

11. The _dome_, or _cupola_, is a hemispherical or convex covering to a building or a part of it. When built of stone it is a very strong kind of structure, even more so than the arch, since the tendency of the parts to fall is counteracted by those above and below, as well as by those on each side. During the erection of the cupola, no centring is required, as in the case of the arch.

12. The _roof_ is the most common and cheap covering to buildings. It is sometimes flat, but most commonly oblique, in shape. A roof consisting of two oblique sides meeting at the top, is denominated a _pent_ roof; that with four oblique sides, a _hipped_ roof; and that with two sides, having each two inclinations of different obliquities, a _curb_ or _mansard_ roof. In modern times, roofs are constructed of wood, or of wood covered with some incombustible material, such as tiles, slate, and sheets of lead, tin, or copper. The elementary parts of buildings, as just described, are more or less applicable in almost every kind of architecture.

13. The architecture of different countries has been characterized by peculiarities of form and construction, which, among ancient nations, were so distinct, that their edifices may be identified at the present day even in a state of ruin; and, although nearly all the buildings of antiquity are in a dilapidated state, many of them have been restored, in drawings and models, by the aid of the fragments which remain.

14. The different styles of building which have been recognised by the architect of modern times, are, the Egyptian, the Chinese, the Grecian, the Roman, the Greco-Gothic, the Saracenic, and the Gothic. In all these, the pillar, with its accompaniments, makes a distinguished figure. The following picture has therefore been introduced by way of explanation. The columns are of the Corinthian order of architecture.

15. _The Egyptian style._--The first inhabitants of Egypt lived in mounds, caverns, and houses of mud; and, from these primitive structures, the Egyptians, at a later period, derived their style of architecture. The walls of their buildings were very thick, and sloping on the outside; the roof was flat, and composed of blocks of stone, extending from one wall or pillar to another; and the columns were short and large, being sometimes ten or twelve feet in diameter. Pyramids of prodigious magnitude, and obelisks composed of a single stone, sometimes often exceeding seventy feet in height, are structures peculiarly Egyptian. The architecture of the Hindoos seems to have been derived from primitive structures of a similar character.

16. _The Chinese style._--The ancient Tartars, and other wandering tribes of Asia, appear to have lived in tents; and the Chinese buildings, even at the present day, bear a strong resemblance to these original habitations, since their roofs are concave on the upper side, as if made of canvas instead of wood. Their porticoes resemble the awnings spread out on our shop-windows in the summer. The Chinese build chiefly of wood, although they sometimes use brick and stone.
