+AUTHOR'S PREFACE.
+
+
+Early in the present century the method generally adopted for polishing
+furniture was by rubbing with beeswax and turpentine or with
+linseed-oil. That process, however, was never considered to be very
+satisfactory, which fact probably led to experiments being made for the
+discovery of an improvement. The first intimation of success in this
+direction appeared in the _Mechanic's Magazine_ of November 22, 1823,
+and ran as follows: "The Parisians have now introduced an entirely new
+mode of polishing, which is called _plaque_, and is to wood precisely
+what plating is to metal. The wood by some process is made to resemble
+marble, and has all the beauty of that article with much of its
+solidity. It is even asserted by persons who have made trial of the new
+mode that water may be spilled upon it without staining it." Such was
+the announcement of an invention which was destined ultimately to become
+a new industry.
+
+The following pages commence with a description of the art of French
+Polishing in its earliest infancy, care having been taken by the Author,
+to the best of his ability, to note all the new processes and
+manipulations, as well as to concisely and perspicuously arrange and
+describe the various materials employed, not only for French polishing
+but for the improving and preparation of furniture woods, a matter of
+great importance to the polisher. The arts of Staining and Imitating,
+whereby inferior woods are made to resemble the most costly, are also
+fully treated, as well as the processes of Enamelling, both in
+oil-varnishes and French polish, together with the method of decorating
+the same. The condition of the art of polishing in America is dwelt
+upon, and various interesting articles written by practical polishers in
+the States, which appeared in their trade journal, _The Cabinet-maker_,
+have been revised and printed in this work.
+
+A number of valuable recipes, and other instructive matter, useful alike
+to the amateur and to the practical workman, are also given.

+CHAPTER I.
+
+_THE IMPROVING AND PREPARATION OF
+FURNITURE WOODS._
+
+
+For a French polisher to be considered a good workman he should, in
+addition to his ordinary ability to lay on a good polish, possess
+considerable knowledge of the various kinds of wood used for furniture,
+as well as the most approved method of bringing out to the fullest
+extent their natural tones or tints; he should also be able to improve
+the inferior kinds of wood, and to stain, bleach, or match any of the
+fancy materials to which his art is applied, in a manner that will
+produce the greatest perfection. The following information is given to
+facilitate a thorough knowledge of the above processes.
+
+
+=Improving.=--Iron filings added to a decoction of gall-nuts and vinegar
+will give to ebony which has been discoloured an intense black, after
+brushing over once or twice. Walnut or poor-coloured rosewood can be
+improved by boiling half an ounce of walnut-shell extract and the same
+quantity of catechu in a quart of soft-water, and applying with a
+sponge. Half a pound of walnut husks and a like quantity of oak bark
+boiled in half a gallon of water will produce much the same result.
+Common mahogany can be improved by rubbing it with powdered red-chalk
+(ruddle) and a woollen rag, or by first wiping the surface with liquid
+ammonia, and red-oiling afterwards. For a rich mild red colour,
+rectified spirits of naphtha, dyed with camwood dust, or an oily
+decoction of alkanet-root. Methylated spirits and a small quantity of
+dragon's blood will also produce a mild red. Any yellow wood can be
+improved by an alcoholic solution of Persian berries, fustic, turmeric,
+or gamboge. An aqueous decoction of barberry-root will serve the same
+purpose. Birch when preferred a warm tint may be sponged with oil, very
+slightly tinted with rose-madder or Venetian red; the greatest care
+should be used, or it will be rendered unnatural in appearance by
+becoming too red. Maple which is of a dirty-brown colour, or of a cold
+grey tint, and mahogany, ash, oak, or any of the light-coloured woods,
+can be whitened by the bleaching fluid (see "MATCHING"). Numerous
+materials may be improved by the aid of raw linseed-oil mixed with a
+little spirits of turpentine. Artificial graining may be given to
+various woods by means of a camel-hair pencil and raw oil; two or three
+coats should be given, and after standing for some time the ground
+should have one coat of oil much diluted with spirits of turpentine, and
+then rubbed off.
+
+
+=Matching.=--Old mahogany furniture which has been repaired may be
+easily matched by wiping over the new portions with water in which a
+nodule of lime has been dissolved, or by common soda and water. The
+darkeners for general use are dyed oils, logwood, aquafortis, sulphate
+of iron, and nitrate of silver, with exposure to the sun's rays. For new
+furniture in oak, ash, maple, etc., the process of matching requires
+care and skill. When it is desirable to render all the parts in a piece
+of furniture of one uniform tone or tint, bleach the dark parts with a
+solution of oxalic acid dissolved in hot water (about two-pennyworth of
+acid to half a pint of water is a powerful solution); when dry, if this
+should not be sufficient, apply the white stain (see pp. 11, 12)
+delicately toned down, or the light parts may be oiled. For preserving
+the intermediate tones, coat them with white polish by means of a
+camel-hair pencil. On numerous woods, carbonate of soda and bichromate
+of potash are very effective as darkeners, as are also other
+preparations of an acid or alkaline nature, but the two given above are
+the best.
+
+A good way of preparing these darkeners, says the "French Polisher's
+Manual," an excellent little work published in Perth some years since,
+is to procure twopennyworth of carbonate of soda in powder, and dissolve
+it in half a pint of boiling water; then have ready three bottles, and
+label them one, two, three. Into one put half the solution, and into the
+other two half a gill each; to number two add an additional gill of
+water, and to number three two gills. Then get the same quantity of
+bichromate of potash, and prepare it in a like manner; you will then
+have six staining fluids for procuring a series of brown and dark tints
+suitable for nearly all classes of wood.
+
+The bichromate of potash is useful to darken oak, walnut, beech, or
+mahogany, but if applied to ash it renders it of a greenish cast. If a
+sappy piece of walnut should be used either in the solid or veneer,
+darken it to match the ground colour, and then fill in the dark markings
+with a feather and the black stain (see pp. 10, 11). The carbonate
+solutions are generally used for dark surfaces, such as rosewood
+represents, and a still darker shade can be given to any one by oiling
+over after the stain is dry. The better way of using these chemical
+stains is to pour out into a saucer as much as will serve the purpose,
+and to apply it quickly with a sponge rubbed rapidly and evenly over the
+surface, and rubbed off dry immediately with old rags. Dark and light
+portions, between which the contrast is slight, may be made to match by
+varnishing the former and darkening the latter with oil, which should
+remain on it sufficiently long; by this means the different portions may
+frequently be made to match without having recourse to bleaching or
+staining.
+
+
+=Painting.=--The next process is painting. It frequently happens in
+cabinet work that a faulty place is not discovered until after the work
+is cleaned off; the skill of the polisher is then required to paint it
+to match the other. A box containing the following colours in powder
+will be found of great utility, and when required for use they should be
+mixed with French polish and applied with a brush. The pigments most
+suitable are: drop black, raw sienna, raw and burnt umber, Vandyke
+brown, French Naples yellow (bear in mind that this is a very opaque
+pigment), cadmium yellow, madder carmine (these are expensive), flake
+white, and light or Venetian red; before mixing, the colours should be
+finely pounded. The above method of painting, however, has this
+objection for the best class of furniture, that the effects of time will
+darken the body of the piece of furniture, whilst the painted portion
+will remain very nearly its original colour. In first-class work,
+therefore, stained polishes or varnishes should be applied instead of
+these pigments.
+
+
+=Dyed Polishes.=--The methods of dyeing polish or
+varnish are as follows: for a red, put a little alkanet-root or camwood
+dust into a bottle containing polish or varnish; for a bright yellow, a
+small piece of aloes; for a yellow, ground turmeric or gamboge; for a
+brown, carbonate of soda and a very small quantity of dragon's blood;
+and for a black, a few logwood chips, gall-nuts, and copperas, or by the
+addition of gas-black.
+
+The aniline dyes (black excepted) are very valuable for dyeing polishes,
+the most useful being Turkey-red, sultan red, purple, and brown. A small
+portion is put into the polish, which soon dissolves it, and no
+straining is required. The cheapest way to purchase these dyes is by the
+ounce or half-ounce. The penny packets sold by chemists are too
+expensive, although a little goes a long way.
+
+
+
+
+CHAPTER II.
+
+_STAINS AND IMITATIONS._
+
+
+In consequence of the high price demanded for furniture made of the
+costly woods, the art of the chemist has been called into requisition to
+produce upon the inferior woods an analogous effect at a trifling
+expense. The materials employed in the artificial colouring of wood are
+both mineral and vegetable; the mineral is the most permanent, and when
+caused by chemical decomposition within the pores it acts as a
+preservative agent in a greater or less degree. The vegetable colouring
+matters do not penetrate so easily, probably on account of the affinity
+of the woody fibre for the colouring matter, whereby the whole of the
+latter is taken up by the parts of the wood with which it first comes
+into contact. Different intermediate shades, in great variety, may be
+obtained by combinations of colouring matters, according to the tint
+desired, and the ideas of the stainer. The processes technically known
+as "grounding and ingraining" are partly chemical and partly mechanical,
+and are designed to teach the various modes of operation whereby the
+above effects can be produced. We will commence with
+
+
+=Imitation Mahogany.=--Half a pound of madder-root, and two ounces of
+logwood chips boiled in a gallon of water. Brush over while hot; when
+dry, go over it with a solution of pearlash, a drachm to a pint. Beech
+or birch, brushed with aquafortis in sweeping regular strokes, and
+immediately dried in front of a good fire, form very good imitations of
+old wood. Venetian red mixed with raw linseed-oil also forms a good
+stain.
+
+The following is a method in common use by French cabinet-makers. The
+white wood is first brushed over with a diluted solution of nitrous
+acid; next, with a solution made of methylated spirits one gill,
+carbonate of soda three-quarters of an ounce, and dragon's blood a
+quarter of an ounce; and a little red tint is added to the varnish or
+polish used afterwards. Black American walnut can be made to imitate
+mahogany by brushing it over with a weak solution of nitric acid.
+
+
+=Imitation Rosewood.=--Boil half a pound of logwood chips in three pints
+of water until the decoction is a very dark red; then add an ounce of
+salt of tartar. Give the work three coats boiling hot; then with a
+graining tool or a feather fill in the dark markings with the black
+stain. A stain of a very bright shade can be made with methylated
+spirits half a gallon, camwood three-quarters of a pound, red-sanders
+a quarter of a pound, extract of logwood half a pound, aquafortis one
+ounce. When dissolved, it is ready for use. This makes a very bright
+ground. It should be applied in three coats over the whole surface, and
+when dry it is glass-papered down with fine paper to a smooth surface,
+and is then ready for graining. The fibril veins are produced by passing
+a graining tool with a slight vibratory motion, so as to effect the
+natural-looking streaks, using the black stain. A coat of the bichromate
+of potash solution referred to on page 4 will make wildly-figured
+mahogany have the appearance of rosewood.
+
+
+=Imitation Walnut.=--A mixture of two parts of brown umber and one part
+of sulphuric acid, with spirits of wine or methylated spirits added
+until it is sufficiently fluid, will serve for white wood. Showy
+elm-wood, after being delicately darkened with the bichromate solution
+No. 1, page 4, will pass for walnut; it is usually applied on the cheap
+loo-table pillars, which are made of elm-wood. Equal portions of the
+bichromate and carbonate solutions (see page 4), used upon American
+pine, will have a very good effect.
+
+Another method for imitating walnut is as follows: One part (by weight)
+of walnut-shell extract is dissolved in six parts of soft-water, and
+slowly heated to boiling until the solution is complete. The surface to
+be stained is cleaned and dried, and the solution applied once or twice;
+when half-dry, the whole is gone over again with one part of chromate of
+potash boiled in five parts of water. It is then dried, rubbed down, and
+polished in the ordinary way.
+
+The extract of walnut-shells and chromate of potash are procurable at
+any large druggist's establishment. A dark-brown is the result of the
+action of copper salts on the yellow prussiate of potash; the sulphate
+of copper in soft woods gives a pretty reddish-brown colour, in streaks
+and shades, and becomes very rich after polishing or varnishing.
+Different solutions penetrate with different degrees of facility. In
+applying, for instance, acetate of copper and prussiate of potash to
+larch, the sap-wood is coloured most when the acetate is introduced
+first; but when the prussiate is first introduced, the heart-wood is the
+most deeply coloured. Pyrolignite of iron causes a dark-grey colour in
+beech, from the action and tannin in the wood on the oxide of iron;
+while in larch it merely darkens the natural colour. Most of the tints,
+especially those caused by the prussiates of iron and copper, are
+improved by the exposure to light, and the richest colours are produced
+when the process is carried out rapidly.
+
+
+=Imitation Ebony.=--Take half a gallon of strong vinegar, one pound of
+extract of logwood, a quarter of a pound of copperas, two ounces of
+China blue, and one ounce of nut-gall. Put these into an iron pot, and
+boil them over a slow fire till they are well dissolved. When cool, the
+mixture is ready for use. Add a gill of iron filings steeped in vinegar.
+The above makes a perfect jet black, equal to the best black ebony. A
+very good black is obtained by a solution of sulphate of copper and
+nitric acid; when dry, the work should have a coat of strong logwood
+stain.
+
+
+=Imitation Oak.=--To imitate old oak, the process known as "fumigating"
+is the best. This is produced by two ounces of American potash and two
+ounces of pearlash mixed together in a vessel containing one quart of
+hot water.
+
+Another method is by dissolving a lump of bichromate of potash in warm
+water; the tint can be varied by adding more water. This is best done
+out of doors in a good light. Very often in sending for bichromate of
+potash a mistake is made, and chromate of potash is procured instead;
+this is of a yellow colour, and will not answer the purpose. The
+bichromate of potash is the most powerful, and is of a red colour. A
+solution of asphaltum in spirits of turpentine is frequently used to
+darken new oak which is intended for painter's varnish, or a coating
+of boiled oil.
+
+Another method of imitating new oak upon any of the inferior
+light-coloured woods is to give the surface a coat of Stephens's
+satin-wood stain, and to draw a soft graining-comb gently over it, and
+when the streaky appearance is thus produced a camel-hair pencil should
+be taken and the veins formed with white stain. This is made by
+digesting three-quarters of an ounce of flake white (subnitrate of
+bismuth), and about an ounce of isinglass in two gills of boiling water;
+it can be made thinner by adding more water, or can be slightly tinted
+if desired.
+
+Proficients in staining and imitating can make American ash so like oak
+that experienced judges are frequently deceived, the vein and shade of
+the spurious wood looking nearly as natural as the genuine. After the
+veining is done, it should be coated with white hard varnish, made
+rather thin by adding more spirits, after which the ground can be
+delicately darkened if required.
+
+
+=Imitation Satin-wood.=--Take methylated spirits one quart, ground
+turmeric three ounces, powdered gamboge one and a-half ounces. This
+mixture should be steeped to its full strength, and then strained
+through fine muslin, when it will be ready for use. Apply with a sponge,
+and give two coats; when dry, glass-paper down with fine old paper. This
+makes a good imitation for inside work. By the addition of a little
+dragon's blood an orange tint can be produced. A yellow colour can also
+be given to wood by boiling hot solutions of turmeric, Persian berries,
+fustic, etc. but the colour is very fugitive. A more permanent colour
+results from nitric acid, and last of all by the successive introduction
+of acetate of lead and chromate of potash. Sulphate of iron also stains
+wood of a yellowish colour when used as a preservative agent, so much
+so, that the use of corrosive sublimate is recommended for this purpose
+when it is desirable to preserve the light colour.
+
+
+=A Blue Stain.=--This dye can be obtained by dissolving East Indian
+indigo in arsenious acid, which will give a dark blue. A lighter blue
+can be obtained by hot solutions of indigo, of sulphate of copper, and
+by the successive introduction of pyrolignite of iron and prussiate of
+potash.
+
+
+=A Green Stain.=--Dissolve one ounce of Roman vitriol in a quart of
+boiling water, to which is added one ounce of pearlash; the mixture
+should then be forcibly agitated, and a small quantity of pulverised
+yellow arsenic stirred in. A green is also the result of successive
+formations in the pores of the wood of a blue and a yellow as above
+indicated, and by a hot solution of acetate of copper in water. A
+yellowish green may be obtained by the action of copper salts on the red
+prussiate of potash.
+
+
+=A Purple Stain.=--Boil one pound of logwood chips in three quarts of
+water, until the full strength is obtained; then add four ounces of
+pearlash and two ounces of powdered indigo. When these ingredients are
+thoroughly dissolved, it is ready for use, either hot or cold. A purple
+is also obtained by a boiling hot solution of logwood and Brazil-wood,
+one pound of the former and one quarter of a pound of the latter to a
+gallon of water.
+
+
+=A Red Stain.=--Methylated spirits one quart, Brazil-wood three ounces,
+dragon's blood half an ounce, cochineal half an ounce, saffron one
+ounce. Steep the whole to its full strength, and strain. A red can also
+be produced by macerating red-sanders in rectified spirits of naphtha.
+An orange-red colour may be obtained by the successive action of
+bichloride of mercury and iodide of potash, madder, and ammoniacal
+solutions of carmine.
+
+
+=Imitation Purple-wood Stain.=--Grind a piece of green copperas on
+coarse glass-paper, and mix with polish coloured with red-sanders. This
+makes a capital purple stain, and is used by French cabinet-makers.
+
+These dyestuffs may be much improved by the addition of a mordant
+applied after they are dry; this will greatly assist in modifying and
+fixing the tints and shades which the dyes impart. The best thing for
+the purpose, in the writer's opinion, is clear ox-gall, which, besides
+being useful as a mordant, will destroy all unctuous matter.
+
+
+=Chemicals used in Staining.=--It may perhaps be useful here to give the
+common or popular names of the chemicals employed in the operations of
+staining and imitating, as few polishers know them by the scientific
+names used by chemists:--
+
+Nitric acid is but another phrase for aquafortis.
+Sulphuric acid, for oil of vitriol.
+Ammonia, for spirits of hartshorn.
+Sulphate of magnesia, for Epsom salts.
+Nitrate of potass, for sal prunelle.
+Chlorine, for aqua regia.
+Sulphate of copper, for blue vitriol.
+Subborate of soda, for borax.
+Superoxalate of potass, for salts of sorrel.
+Hydrochlorate of ammonia, for sal ammoniac.
+Subnitrate of bismuth, for flake white.
+Acetic acid, for vinegar.
+Acetate of lead, for sugar of lead.
+Sulphate of lime, for gypsum.
+Carbonate of potass, for pearlash.
+Bitartrate of potass, for cream of tartar.
+Nitrate of silver, for lunar caustic.
+Supercarbonate of iron, for plumbago.
+Cyanide of iron, for Prussian blue.
+Subacetate of copper, for common verdigris.
+Susquecarbonate of ammonia, for sal volatile.
+Alcohol, for pure spirit.
+Sulphate of iron, for green copperas.
+Sulphate of zinc, for white copperas.
+
+
+=Process of Staining.=--The natural qualities of woods are very
+variable; so also are the textures of the different sorts usually used
+for staining. It will be readily perceived that there is no fixed
+principle upon which certain peculiar tints or shades can be produced
+with any degree of certainty. In order to arrive at the best results,
+the stainer is recommended to observe the following rules:--
+
+All dry stuffs are best reduced to powder, when it is possible, before
+macerating or dissolving them.
+
+All liquids should be strained or filtered before use.
+
+The requisite ingredients should always be tested before a free use is
+made of them, as the effect produced by a coat of stain cannot be
+accurately ascertained until it is thoroughly dry.
+
+Amateurs in staining had far better coat twice or thrice with a weak
+stain than apply a strong one; for if too dark a tint is first obtained
+it is often irremediable. Flat surfaces will take stain more evenly if a
+small portion of linseed-oil is first wiped over, well rubbed off, and
+allowed to dry, then lightly papered down with fine glass-paper. End-way
+wood which is of a spongy nature should first have a coat of thin
+varnish, and when dry well glass-papered off. For applying stain a flat
+hog-hair tool is the best; and for a softener-down a badger-hair tool is
+used. For mahogany shades and tints a mottler will be found of service,
+as will also a soft piece of Turkey sponge. For oak, the usual steel
+graining-comb is employed for the streaking, and for veining badger
+sash-tools and sable pencils.
+
+
+=Ready-made Wood Stains.=--There are numerous stains suitable for common
+work in the market obtainable at a small cost by residents in London,
+but it is cheaper for those who reside in country towns to make their
+own, if only a small quantity is required. The principal makers of wood
+stains are H. C. Stephens, of 191, Aldersgate-street, E.C., and Jackson,
+213, Union-street, Southwark, S.E. These makers prepare stains in a
+liquid state, and also in powders for oak, walnut, mahogany, satin-wood,
+ebony, and rosewood. The powders are sold in packages at 8s. per lb. or
+1s. for two ounces, and are soluble in boiling water. Judson, of 77,
+Southwark-street, S.E., makes a mahogany powder in sixpenny packets, and
+any reliable oilman will sell a good black stain at 8d. per quart, or a
+superior black stain at 1s. 2d. per quart. Fox, of 109, Bethnal
+Green-road, also prepares stains in a liquid state.

+
+_FRENCH POLISHING._
+
+
+=The Polish Used.=--The oil or wax polish was used for all kinds of
+furniture before the introduction of French polish, the invention of
+which, as its name implies, is due to French cabinet-makers. It was
+first introduced into England about seventy years since; some time
+elapsed, however, before it was brought to a high state of perfection.
+At first apprentices or porters were entrusted with the polishing, they
+having been usually called upon to do the wax polishing; but in course
+of time it was found that its successful adoption implied the possession
+of considerable skill, and it came to be regarded as an art of no little
+importance--so much so, that the early polishers who had perfected
+themselves used to work in a shop with closed doors, lest the secret of
+their success should be discovered. From that time polishing became a
+separate branch of the cabinet business.
+
+The following original recipe as first invented has been extracted from
+a French work, the _Dictionnaire Technologique_, not, however, for its
+usefulness (it having gone into disuse many years ago), but as a matter
+of curiosity:--
+
+ "_French Polish._"
+
+ Gum sandarach 14 ounces 2 drachms
+ Gum mastic in drops 7 " 2 "
+ Shellac (the yellower the better) 14 " 2 "
+ Alcohol of 0.8295 specific gravity 3 quarts and 1 pint.
+
+"Pound the resinous gums, and effect their solution by continued
+agitation, without the aid of heat; if the woods are porous, add seven
+ounces one drachm of Venice turpentine. If an equal weight of ground
+glass be added, the solution is more quickly made, and is also otherwise
+benefited by it. Before using, the wood should be made to imbibe a
+little linseed-oil, the excess of which should be removed by an old
+flannel."
+
+Notwithstanding the improvement made upon the old processes by this new
+method, it was by no means considered to be perfect, for the polish was
+found to impart its brown tinge to the light-coloured woods, especially
+in marqueterie work, and to deteriorate their appearance. It will be
+readily seen that it was a great desideratum among polishers to render
+shellac colourless, as, with the exception of its dark-brown hue, it
+possesses all the properties essential to a good polish or spirit
+varnish in a higher degree than any of the other resins.
+
+In 1827 the Society of Arts came forward with its valuable aid and
+offered a premium of a gold medal, or thirty guineas, "for a polish or
+varnish made from shell or seed-lac, equally hard, and as fit for use in
+the arts as that at present prepared from the above substance, but
+deprived of its colouring matter." After numerous experiments, this
+long-felt want was perfectly attained by Dr. Hare, who was awarded the
+premium. His method was as follows: "Dissolve in an iron kettle one part
+of pearlash in about eight parts of water; add one part of shell or
+seed-lac, and heat the whole to ebullition. When the lac is dissolved,
+cool the solution, and impregnate it with chlorine till the lac is all
+precipitated. The precipitate is white, but its colour deepens by
+washing and consolidation; dissolved in alcohol, lac, bleached by the
+process above mentioned, yields a polish or varnish which is as free
+from colour as any copal varnish." At the present time shellac is
+bleached by filtration over animal charcoal.
+
+Numerous experiments were afterwards made in the manufacture of
+polishes; several chemists devoted their attention to its manufacture,
+and an improved polish was soon produced which was used for a number of
+years. The following are its proportions:--
+
+ Shellac 14 ounces.
+ Sandarach 3/4 ounce.
+ White resin 3/4 "
+ Benzoin 3/4 "
+ Gum thus 3/4 "
+ O.P. finishing spirit 1/2 a gallon.
+
+The "filling-in" processes also began to be used, which effected a
+considerable saving in the quantity of polish usually required, and in
+consequence of the expensiveness of spirits of wine rectified spirits of
+naphtha was used as a substitute for the making of polishes, etc.; but
+it was discovered that its continued use soon affected the eyesight of
+the workmen, and it had to be abandoned, the methylic alcohol, pyroxylic
+spirit, or wood spirit, as it has been differently called, taking its
+place. This was first discovered by Mr. Philip Taylor in 1812, and is
+obtained by distilling wood. Messrs. Dumas & Peligot, after analysing
+it, determined that it contained 37.5 per cent. of carbon, 12.5 per
+cent. of hydrogen, and 50 per cent. of oxygen. When pure, it remains
+clear in the atmosphere; but for the sake of economy it is often
+employed in the manufacture of other compounds called methylated. This
+spirit began to be much used in the manufacture of polishes and
+varnishes in the year 1848, and has continued to be much used ever
+since.
+
+The wonderful improvements which have been effected in polishes since
+their first introduction obviously prove that they have now arrived at a
+very high point of perfection, and polishing is now justly acknowledged,
+both by skilled artisans and connoisseurs, to be an important decorative
+art. French polish or varnish at the present time can easily be obtained
+at most chemists or oil shops, or direct from the manufacturers, amongst
+whom may be mentioned Mr. W. Urquhart, 327, Edgware-road, W.; Messrs.
+Turner & Sons, 7 to 9, Broad-street, Bloomsbury, W.C.; Messrs. William
+Fox & Son, Bethnal Green-road, E.; Mr. G. Purdom, 49, Commercial-road,
+E.
+
+The London prices are: Best French polish, 5s. 6d. per gallon; best
+white polish, 9s. per gallon; brown or white hard varnish, 8s. per
+gallon; patent glaze, 10s. per gallon; methylated spirits, 3s. 3d. per
+gallon. For those who prefer to make their own, the following will be
+found an excellent recipe:--
+
+ 12 ounces of orange shellac.
+ 1 ounce of benzoin.
+ 1 ounce of sandarach.
+ 1/2 gallon of methylated spirits.
+
+Pound the gums well before mixing with the spirit, as this will hasten
+their dissolution. White polish for white wood and marqueterie work
+should be made with bleached shellac instead of the above. In making
+polishes or varnishes, the mixture will frequently require shaking until
+dissolved.
+
+
+=Rubbers.=--In commencing to polish, the materials required are old
+flannel for the rubbers and clean old linen or cotton rags for the
+coverings, the softer the better; some polishers, however, prefer white
+wadding for rubbers instead of flannel. Rubbers for large surfaces are
+usually made of soft old flannel, firmly and compactly put together
+somewhat in the form of a ball, and the more they possess softness and
+compactness, and are large and solid, the more quickly and
+satisfactorily will they polish extensive surfaces. Small pliable
+rubbers are usually employed for chairs or light frame-work. Perhaps for
+a beginner a rubber made of old flannel may be best, as it takes some
+little practice to obtain the necessary lightness of hand.
+
+The rubber for "spiriting-off" should be made up from a piece of old
+flannel or woollen cloth, and covered with a piece of close rag,
+doubled. Carefully fold the rag and screw it round at the back to make
+it as firm as possible, and sprinkle some spirit on the face of it just
+as it is covered; then give it two or three good smacks with the palm of
+the hand, and begin by laying on as lightly as possible for the first
+few strokes and gradually increase the pressure as the rubber gets dry;
+then take off the first fold of the cover and work it perfectly dry.
+
+The rubber should present to the wood you are about to work on a
+smooth-rounded or convex surface. Have beside you linseed-oil in one
+receptacle, and some French polish in another. Apply one drop of polish
+and one drop of oil, and polish with a circular movement--traversing
+steadily the _whole_ surface to be polished, and from time to time, as
+may be necessary (when the rubber gets sticky and harsh, indicating that
+the inside needs replenishing with more polish), open and apply more of
+it, and again draw over the linen cover, holding it tightly to form the
+convex face proper to do the work. After replenishing, the rubber will
+probably need a little more oil to help it to work smoothly. Having thus
+worked on one coat of polish evenly over all the wood until it has got
+what may best be described as a _full look_, set it aside for two or
+three hours to sink in and become hard, and when completely dry, lightly
+paper off with glass-paper (very finest), afterwards dusting the surface
+to remove any trace of powder, and lay on a second coat of polish in the
+same method. Then allow twenty-four hours to dry. Another light papering
+may possibly be needed--dust off as before recommended and let the wood
+have a _third_ coat of polish.
+
+For this third coat a fresh rubber should be made, the inside being
+sparingly supplied with spirits of wine instead of polish. Put a double
+fold of linen over it, touch it with one drop of oil, and go very
+lightly and speedily over the whole work.
+
+In spiriting-off--the object of which is to remove any trace of smudge
+that may blur the surface unless removed thus by spirit--you should go
+gently to work, using a very light hand, or you may take the polish off
+as well, amateurs more especially.
+
+
+=Position.=--All work should be placed in an easy and accessible
+position while it is being polished, so that the eye may readily
+perceive the effect of the rubber; this will greatly help to relieve the
+difficulties attending the polishing of a fine piece of furniture. It
+should also be kept quite firm, so that it cannot possibly move about.
+The most suitable benches for polishers are the ordinary cabinet-makers'
+benches, with the tops covered with thick, soft cloths; these cloths
+should not be fastened down, it being an advantage to be able to remove
+them when required. When a piece of work too large to be placed upon the
+bench is in hand, pads will be found useful to rest it upon. These can
+be made by covering pieces of wood about two feet in length by three
+inches in width with cloth several times doubled, the work being placed
+so that a good light falls upon it. All thin panelling should be tacked
+down upon a board by the edges while polishing.
+
+
+=Filling-in.=--The first process the wood usually undergoes is
+"filling-in." This consists in rubbing into the pores of the wood
+Russian tallow and plaster of Paris, which have been previously heated
+and mixed together so as to form a thick paste. For rosewood, or to
+darken mahogany, a little rose-pink should be added. After well rubbing
+in, the surface should be cleared from all the surplus paste with the
+end of the scraper, and then rubbed off with shavings or old rags, and
+made quite clean. For birch or oak, some use whiting or soft putty
+moistened with linseed-oil for the filling; this preparation prevents in
+a great measure the rising of the grain. For white delicate woods, such
+as sycamore, maple, or satin-wood, plaster of Paris, mixed with
+methylated spirit, is used. When polishing pine, a coat of Young's
+patent size (2d. per lb.) is used instead of the above mixtures, and
+when dry is rubbed down with fine glass-paper.
+
+Some workmen, who regard their modes of filling-in as important secrets,
+do their work surprisingly quick by the methods here given. The various
+processes are soon acquired by a little practice, and contribute greatly
+to the speedy advancement of a smooth and imporous ground, which is the
+most important point to observe in polishing.
+
+
+=Applying the Polish.=--In commencing to use the polish some are
+provided with a small earthenware dish, into which the polish is poured
+for wetting the rubbers; while others make a slit in the cork of the
+polish bottle, and so let it drip on to the rubber; whichever method is
+adopted, the rubber should not be saturated, but receive just enough to
+make a smear. Every time after wetting the rubber and putting on the
+cover it should be pressed upon the palm of the hand, or if a small
+rubber it can be tested between the thumb and finger. This is an
+important operation, for by it the polisher can easily tell the exact
+state of moisture, and at the same time, by the pressure being applied,
+the moisture is equalised. The tip of the finger should then be just
+dipped into the linseed-oil, and applied to the face of it; if the
+rubber should be rather sappy, the greatest care must be used or a
+coarse streaky roughness will be produced; extreme lightness of hand is
+required until the rubber is nearly dry. (It would be a serious error to
+bear heavily on the rubber while the surface is moist; to do so, and to
+use too much oil on the rubber, are the causes of many failures in
+polishing.)
+
+In commencing to work, pass the rubber a few times gently and lightly
+over the surface in the direction of the grain; then rub across the
+grain in a series of circular movements, all one way, in full and free
+sweeping strokes, until the rubber is dry. Continue this operation until
+the pores are filled in, and the surface assumes a satisfactory
+appearance. It should then be left for about twelve hours; the polish
+will be well into the wood by that time. The polish should then be
+carefully rubbed down with No. glass-paper; this will remove the atomic
+roughness usually caused by the rising of the grain during the sinking
+period. In flat-surface work a paper cork can be used, and the rubbing
+lightly and regularly done in a careful manner, so as to avoid rubbing
+through the outer skin, especially at the edges and corners, or the work
+will be irremediably defaced.
+
+The woods which possess a rising grain are well known to polishers;
+these are the light-coloured woods with a coarse grain, viz., ash,
+birch, and oak. This rising of the grain can in a great measure be
+prevented by passing a damp sponge over the work before commencing the
+polishing, allowing it to dry, and papering it. After the rubbing or
+smoothing-down process is finished, the work should be well dusted; the
+polishing can then recommence. The above operation must be again
+repeated with a rotary motion and gradually increased pressure as the
+rubber gets dry, and finished by lighter rubbings the way of the grain;
+this will remove any slight marks that may be occasioned by the circular
+movements of the rubber.
+
+Working too long on any one part is to be avoided, nor should the rubber
+be allowed to stick even for an instant, or it will pull the coating of
+polish off to the bare wood. The rubber should be covered with a clean
+part of the rag as soon as a shiny appearance becomes apparent upon it,
+or at each time of damping, and less oil should be used towards the end
+of the operation, so as to gradually clear it all off from the surface.
+Rubber marks can be removed by rubbing in a direction the reverse of the
+marks with a half-dry rubber and increased pressure. When the work has
+received a sufficient body, in finishing the drying of the last rubber,
+ply it briskly the way of the grain to produce a clean dry surface for
+the spiriting-off.
+
+The following is the method usually employed on fine carved or turned
+work when finished in the best style. In the first place it is embodied
+with polish, using a small rubber for the operation, after which it
+should have one coat of shellac (two parts by weight of shellac to one
+of spirits) applied with a brush, and when dry it should be carefully
+smoothed down with flour paper, the utmost caution being observed in
+dealing with the sharp edges, or the carving will be spoiled. Then it is
+embodied with polish again, and one coat of glaze applied with the
+greatest care. A few hours should be allowed to harden, and then
+finished off with a rubber slightly damped with thin polish. This is an
+expensive method, but it will pay in appearance for all the time
+bestowed.
+
+For the best class of cabinet and pianoforte work in amboyna or
+burr-walnut it is advisable not to use linseed-oil on the sole of the
+rubber when polishing, but the best hog's lard; the reason for this is
+that these veneers being so extremely thin and porous the oil will
+quickly penetrate through to the groundwork, softening the glue, and
+causing the veneers to rise in a number of small blisters. Of course,
+this is not always the case, but the use of lard instead of oil will be
+found a good preventative. Lard is also used on the above class of work
+when it is desirable to preserve the colour of the wood in its natural
+state.
+
+The following method is employed for the best work: Immediately on
+receiving the job from the cabinet-maker, a good coating of thin, clean
+glue should be applied with a sponge or brush; this is allowed to dry,
+and thoroughly harden; it is then cleaned off, using the scraper and
+glass-paper, cutting it down to the wood. The bodying-in with white
+polish is the next process, the usual sinking period being allowed; it
+is again cleaned off, but the scraper this time should not quite reach
+the wood. Then embody again, and treat in a like manner. In getting up
+the permanent body, commence with a slight embodying; let this stand,
+and when the sinking period is over rub it down with a felt rubber and
+powdered pumice-stone; continue this several times, till the surface
+presents a satisfactory appearance, and the job is ready for the
+spiriting process. By this means the wood will retain its natural
+colour, and a beautiful transparent polish will result, and remain for a
+number of years. This also is an expensive process, but the result
+cannot be obtained in any other way.
+
+
+=Spiriting-off.=--Most polishers affirm that if an interval of at least
+a couple of hours elapse between the final embodying and the
+spiriting-off the brilliancy of the polish will be improved, and remain
+harder and more durable. The spirit is applied in exactly the same way
+as the polish, and the same rubber can be used, but it should be covered
+with more than one fold of the soft linen rag; care should be taken not
+to make it very wet, or the gum on the surface of the work will be
+redissolved, and a dulness instead of a brilliancy will result. If the
+spirit should be very strong, the rubber should be breathed upon before
+using, and a little more oil taken up; some, however, prefer to mix a
+little polish with the spirit, while others prefer the spirit to be
+weakened by exposure to the air for a few hours; experience alone must
+be the teacher in this particular; but if the spirit should not "bite,"
+as it is termed, all will be well. The last rubber should be worked a
+little longer than usual, and a trifle quicker, so as to remove the
+slight greasy moisture on the surface.
+
+The finishing touch is given to the work by a soft rag loosely rolled up
+and just a few drops of spirit dropped upon it, applied quickly the way
+of the grain. This will remove every defect, and leave it clear and
+brilliant. If, in a short time after finishing, the polish becomes dull
+or rough, it will be owing to too much oil being absorbed in the process
+and working through the surface, combined with dust. It should be
+cleaned off first with a soft cloth, damped with a little warm water,
+and the whole repaired, as at first, with equal parts of polish and
+spirits mixed together, using the least possible damp of oil to make it
+finish clear; there is no danger of its happening again. In all cases
+the work must be rubbed till quite dry, and when nearly so the pressure
+may be increased.
+
+The rubber for spiriting-off should be made up from a piece of old
+flannel, and be covered with a piece of old rag. This is preferable to
+very thin rag, and will give a better finish.
+
+
+=Prepared Spirits.=--This preparation is useful for finishing, as it
+adds to the lustre and durability, as well as removes every defect of
+other polishes, and it gives the surface a most brilliant appearance.
+
+It is made of half a pint of the very best rectified spirits of wine,
+two drachms of shellac, and two drachms of gum benzoin. Put these
+ingredients in a bottle and keep in a warm place till the gum is all
+dissolved, shaking it frequently; when cold add two teaspoonfuls of the
+best clear white poppy oil; shake them well together, and it is fit for
+use.
+
+
+=Antique Style.=--For mediaeval or old English furniture a dull polish is
+generally preferred to a French polish, because it has a gloss rather
+than a brilliant polish, which materially assists in showing up
+mouldings or carvings to the best advantage; it is also more in
+character with the work of the Middle Ages. Another advantage is the
+facility of obtaining a new polish (after being once done) should the
+first one get tarnished, as the finishing process can be performed
+without difficulty by any one, and a new polish obtained each time.
+
+On receiving a job which is required to be done in this style, it should
+be "filled-in" in the usual manner, and afterwards bodied with white
+polish to a good extent; it is then left for a sinking period (say
+twelve hours). The work is then carefully rubbed down with powdered
+pumice-stone and a felt-covered block or rubber, and after well dusting
+it is ready for finishing. The preparation used for this process is
+mainly composed of bees'-wax and turpentine (see Wax Polish, page 87),
+well rubbed in with a piece of felt or a woollen rag, and finished off
+by rubbing briskly with a very soft cloth or an old handkerchief to
+produce a gloss.
+
+
+=Dull or Egg-shell Polish.=--This is another style of finishing for
+mediaeval work; the process is very simple. In commencing a job to be
+finished in this style, the process of "filling-in" and "embodying" are
+first gone through, then a sinking period is allowed, after which it is
+embodied again, till the work is ready for finishing. All the parts
+should be carefully examined to see if there is a good coating of polish
+upon them. This is important, for if the work should be only thinly
+coated it is liable to be spoiled by rubbing through in the last
+process. After allowing a few hours for the surface to harden, a pounce
+bag of powdered pumice-stone should be applied to the work, and a
+felt-covered rubber used, rubbing down in the direction of the grain
+until the work is of the desired dulness.
+
+For the cheaper kind of work done in this style, the first process, of
+course, is the filling-in; then a rubber of wadding is taken and used
+without a cover, made rather sappy with polish and a few drops of oil
+added; and after bodying-in with this sufficiently, the work should be
+stood aside for twelve hours, then rubbed down with some fine worn
+glass-paper. The embodying is then again commenced, a proper rubber and
+cover being used; and when sufficient is put on, and while the surface
+is still soft, the pounce above mentioned should be applied, and rubbed
+down with a piece of wadding slightly moistened with linseed-oil until
+the desired dulness appears. This is becoming the fashionable finish for
+black walnut work.
+
+
+=Polishing in the Lathe.=--The lathe is of more use to a polisher than a
+great many persons outside the trade would imagine. By its aid turned
+work can be finished in a most superior style, and in less time than by
+hand. The articles usually done by the lathe are wood musical
+instruments, such as clarionets, flutes, etc.; also cornice-poles, ends,
+and mahogany rings, the latter being first placed in a hollow chuck and
+the insides done, after which they are finished upon the outside on a
+conical chuck. For table-legs, chair-legs, and all the turnery used in
+the cabinet-work, it will be found of great advantage to finish the
+turned parts before the work is put together.
+
+Most of the best houses in the trade finish their work in this way,
+where all the work is polished out entirely with the rubber. In the
+first place, the filling-in is done. The band is thrown off the pulley
+and the work rubbed in; at the same time the pulley is turned round by
+the left hand. When this is done, the band is replaced and the work
+cleaned off with rags or shavings, the lathe to be driven with speed to
+get a clean surface. When applying the polish the lathe should revolve
+with a very slow motion.
+
+The rubbers best adapted for turned work are made of white wadding, as
+the hollows and other intricacies can be completely finished out with a
+soft rubber. The work should first receive a coating of thick shellac,
+two parts by weight of shellac to one of methylated spirits, and applied
+with a brush or a soft sponge; after a couple of hours this is nicely
+smoothed with fine paper, and the "bodying-in" completed with the soft
+rubber and thin polish. There are numerous hard woods which do not
+require filling-in, amongst which may be mentioned boxwood, cocus,
+ebony, etc.; these may be rapidly polished in the lathe, on account of
+their texture, with the white polish. In spiriting-off a very soft piece
+of chamois leather (if it is hard and creased it will scratch) should be
+damped with methylated spirits, then wrung so that the spirit may be
+equally diffused; the lathe should then be driven at a rapid speed, and
+the leather held softly to the work. In a few minutes, if a dark wood, a
+brilliant surface will be produced.
+

+CHAPTER IV.
+
+_CHEAP WORK._
+
+
+=Glazing.=--Glaze is known to the trade under several names, such as
+slake, finish, and telegraph; it is used only for cheap work, when
+economy of time is a consideration, and is made as follows: mastic, 1
+oz.; benzoin, 5 ozs.; methylated spirit, 5 gills. A superior article can
+be obtained from G. Purdom, 49, Commercial Road, Whitechapel, E., who is
+the manufacturer of a "patent glaze."
+
+First give the work a rubber or two of polish after the "filling-in"; it
+is important to dry the last rubber thoroughly, so that no unctuousness
+remains upon the surface before applying the glaze, otherwise it will be
+of no effect. The way to apply it is as follows: Prepare a rubber as for
+polishing and make it moderately wet, and take only one steady wipe the
+way of the grain, never going over the same surface twice while wet; and
+when dry, if one coat is found not to be enough, apply a second in the
+same manner. For mouldings or the backs and sides of chair-work, this is
+generally considered to be sufficient. Some polishers will persist in
+using glaze to a large extent, even on the best-paid work; but it is not
+recommended, as the surface will not retain its brilliancy for a
+lengthened period, particularly in hot weather. Nothing is so good for
+the best class of work as polishing entirely with French polish.
+
+The way of treating small flat surfaces such as the frames of tables,
+looking-glasses, builders' work, etc., is to first fill in, and give one
+or two rubbers of polish, drying the last rubber thoroughly; then glaze,
+and after a period of two or three hours finish with a rubber slightly
+wetted with thin polish. It is a bad plan to put glaze on newly-spirited
+work, or to re-apply it on old bodies.
+
+The following is another method for cheap work: A coating of clear size
+is first given in a warm state (this can be obtained at most oil-shops),
+and when dry is rubbed down with fine glass-paper, after which a coating
+of varnish is applied with a sponge or a broad camel-hair brush, giving
+long sweeping strokes. The tool should be plied with some degree of
+speed, as spirit varnishes have not the slow setting properties which
+distinguish those of oil, and care should be taken not to go over the
+same part twice. When this is thoroughly hard it is nicely smoothed with
+fine paper, a few rubberfuls of polish is given, and it is then ready
+for spiriting-off.
+
+Another plan is frequently adopted for cheap work: Make a thin paste
+with plaster of Paris, suitably tinted and watered, and well rub in
+across the grain with a piece of felt or old coarse canvas till the
+pores are all full; any superfluity should be instantly wiped off from
+the surface before it has time to set. The succeeding processes are
+papering and oiling. In applying the polish, which should be done
+immediately after oiling, the rubber should be made rather sappy with
+thin polish, and worked without oil. During the embodying a pounce-bag
+containing plaster of Paris is sparingly used; this application tends to
+fill the pores and also to harden the body of polish on the exterior,
+but too much should not be used, or it will impart a semi-opaque
+appearance to the work. This first body is allowed sufficient time to
+harden; it is then rubbed down lightly with flour paper or old worn No.
+1, and then embodied with thicker polish or a mixture of polish and
+varnish, and the smallest quantity of oil applied to the rubber. When a
+sufficient body of polish is given to the work, the surface is rubbed
+very carefully with a lump of moist putty plied in the longitudinal
+direction of the grain; this will bring up a gloss, and very little
+spiriting will be required.
+
+
+=Stencilling.=--An imitation of marqueterie on light-coloured woods can
+be obtained by the following method: Cut a stencil pattern in stout
+cartridge paper (this is best done upon a piece of glass with the point
+of a sharp penknife), and place it on the centre of a panel or wherever
+required, and have ready some gas-black mixed with thin polish; apply
+this with a camel-hair pencil over the cut-out pattern, and when it is
+removed finish the lines and touch up with a finer tool. The work should
+be first bodied-in, and when the pattern is dry rubbed down with a piece
+of hair-cloth (the smooth side down) on a cork rubber to a smooth
+surface, after which the polishing can be proceeded with until finished.
+Upon oak this will have the appearance of inlaid work.
+
+
+=Charcoal Polishing.=--A method known as "charcoal polishing" is now
+much used for producing the beautiful dead-black colour which seems to
+have the density of ebony. Its invention is due to French
+cabinet-makers. The woods used by them are particularly well adapted for
+staining black or any other colour, limetree, beech, cherry, pear, soft
+mahogany, or any wood of a close and compact grain being the woods
+usually selected.
+
+The first process is to give the work a coating of camphor dissolved in
+water and made rather strong; this will soon soak into the wood, and
+immediately afterwards another coat composed of sulphate of iron-water
+with a few nut-galls added. These solutions in blending penetrate the
+wood and give it an indelible tinge, and also prevent insects from
+attacking it. After these coats are dry, rub the surface with a hard
+brush (an old scrubbing-brush will do) the way of the grain, after which
+rub the flat parts with natural stick charcoal, and the carved or
+indented portions with powdered charcoal; the softest portion of the
+charcoal only should be used, because if a single hard grain should be
+applied it would seriously damage the surface. The workman should have
+ready at the same time a preparation of linseed-oil and essence of
+turpentine (linseed-oil one gill, and essence of turpentine one
+teaspoonful), a portion of which should be freely taken up with a piece
+of soft flannel and well rubbed into the work. These rubbings with the
+preparation and charcoal several times will give the article of
+furniture a beautiful dead-black colour and polish. This method of
+polishing is applied to the black-and-gold furniture, cabinets, etc., in
+imitation of ebony.
+
+Another good black polish is obtained by gas-black being applied to the
+rubber after wetting with French polish, the cover being then put on and
+worked in the usual manner.
+
+These black polishes should not be applied if there are coloured woods
+in the piece of furniture. Should the work be already dyed black, or in
+black veneers, it is best to use white polish, which will greatly help
+to preserve the transparent density of the dye.
+
+
+
+
+CHAPTER V.
+
+_RE-POLISHING OLD WORK._
+
+
+If the piece of furniture requiring to be re-polished should be in bad
+condition, it is best to clean off thoroughly, using the liquid ammonia
+(see page 94), or by the scraper and glass-paper. The indentations may
+be erased by dipping into hot water a piece of thick brown paper three
+or four times doubled and applying it to the part; the point of a
+red-hot poker should be immediately placed upon the wet paper, which
+will cause the water to boil into the wood and swell up the bruise; the
+thickness of the paper prevents the wood from being scorched by the hot
+poker. After the moisture is evaporated, the paper should be again
+wetted if required. If only shallow dents, scratches, and broken parts
+of the polish present themselves, carefully coat them two or three times
+with a thick solution of shellac, and when the last coating becomes hard
+carefully paper down with a piece of old glass-paper and a cork rubber.
+
+If the surface should be in good condition, it is necessary only to
+remove the viscid rust; this is done by friction with a felt-covered
+rubber and pure spirits of turpentine; by this means the polish remains
+unsullied. If the surface should not be in very good condition, a
+flannel should be used smeared with a paste of bathbrick-dust and water,
+or a paste made of the finest emery flour and spirits of turpentine.
+After cleansing, and before the polish is applied, it is a good plan to
+just moisten the surface with raw linseed-oil; this will cause the old
+body to unite with the new one.
+
+In order to carry out the process of re-polishing with facility, it is
+necessary to disunite all the various parts, such as panels, carvings,
+etc., before commencing the operation. The polish is applied in the
+usual manner, and when a good body is laid on the work should be set
+aside for twelve hours, after which it can be finished. It should be
+particularly observed that in polishing no job should be finished
+immediately after the rubbing-down process; a sinking period should
+always be allowed. If the work should be immediately finished, the
+consequences are that in a few hours all the marks and scratches of the
+paper, etc., will be discernible, and the polished surface will present
+a very imperfect appearance, although looking perfect when first
+finished.
+
+Holes and crevices may be well filled up with a cement made in the
+following manner: In a large iron spoon place a lump of beeswax about
+the size of a walnut, a pinch of the pigments mentioned on page 5,
+according to the colour required, a piece of common rosin the size of a
+nut, and a piece of tallow as large as a pea; melt, and it is ready for
+use. Some add a little shellac, but much will make it very brittle. A
+similar substance to the above can be bought at the French warehouses.
+
+
+
+
+CHAPTER VI.
+
+_SPIRIT VARNISHING._
+
+
+Most polishers are agreed that to obtain a good surface with varnish it
+is necessary to give the work, where it is possible to do so, a
+rubberful of polish first, and to thoroughly dry the rubber; but in most
+carved work the surface is not accessible, and the brush must be used.
+Sometimes the carving is extremely coarse, and with an open porous
+grain, in which case it is best to oil it first and then to fine-paper
+it down; by this process a thin paste is formed by the attrition, which
+materially assists in filling up the pores. Before commencing to use the
+varnish have ready an earthenware dish or box,--one of the tins used for
+the preserved meats or fish will answer the purpose,--with two holes
+drilled so that a piece of wire can be fastened diametrically across the
+top; this is called a "regulator," and when the brush is passed once or
+twice over this it prevents an unnecessary quantity of varnish being
+transferred to the work.
+
+
+=Varnishes.=--The ingredients for making
+varnish are very similar to those for making polish, but the proportions
+are somewhat different. Furniture varnish consists of two kinds, viz.:
+the brown-hard and the white-hard; the former is used for dark woods,
+such as mahogany, walnut, rosewood, etc.; whilst the latter is used for
+the light-coloured woods, in conjunction with the white polish. A few
+years since the brown-hard varnish was made from these ingredients:
+
+ 1 gallon of methylated spirit,
+ 40 ozs. of shellac,
+ 4 ozs. of rosin,
+ 5 ozs. of benzoin,
+ 2 ozs. of sandarach,
+ 2 ozs. of white rosin.
+
+The brown-hard varnish which is used at the present time is made
+differently, and produces a better result; it is made from the
+following:
+
+ 1 gallon of methylated spirit,
+ 32 ozs. of shellac,
+ 8 ozs. of rosin,
+ 8 ozs. of benzoin.
+
+The white-hard or transparent varnish for white wood is made with
+
+ 1 gallon of methylated spirit,
+ 32 ozs. of bleached shellac,
+ 24 ozs. of gum sandarach.
+
+In making either polishes or varnishes, all the gums should be first
+pounded and reduced to powder before mixing with the spirit, and when
+mixed they should be occasionally well shaken or stirred, so as to
+hasten their dissolution.
+
+
+=Brushes and Pencils.=--The brushes used for varnishing are either flat,
+in tin, or round, tied firmly to the handle, and made of camel's-hair;
+but the small white bristle-tools and red-sable pencils will frequently
+be found of service in coating delicate carving, or turned work. Varnish
+brushes can be obtained from a quarter of an inch to four inches and
+upwards in width; the most useful brush, however, for general use is
+about an inch wide. It is important that brushes should be cleaned in
+spirits immediately after use, for if laid by in varnish they lose their
+elasticity and are soon spoiled; but if this preservative principle is
+ever neglected, the hardened brush should be soaked in methylated
+spirit, and if wanted for immediate use the spirit will soften the
+varnish quicker if made luke-warm. The spirit should be gently pressed
+out by the finger and thumb. All varnish brushes when not in use should
+be hung up, or kept in such a position that they do not rest upon their
+hairy ends, either in a box or tin free from dust.
+
+
+=Mode of Operation.=--It is usual in varnishing to give the work three
+coats, and always allow each coat to dry thoroughly before applying the
+next. It should be noted that spirit varnishes begin to dry immediately
+they are laid on; therefore, on no account should they be touched with
+the brush again whilst wet, or when dry they will present a rough
+surface. Always ply the brush quickly, and never go over a second time.
+When giving the first or second coats it is unimportant how they are
+applied, whether across the grain or with the grain, but the finishing
+coat should always be with the grain. If the varnish should appear
+frothy when laid on, it is of no consequence, as it will dry smooth if
+equally and evenly applied before a good fire or in a warm atmosphere.
+
+Coloured varnishes can be made in exactly the same manner as coloured
+polishes (see page 6). The beautiful glossy black varnishes so admired
+on Indian cabinet-work, specimens of which can be seen at the Indian
+Museum, are very difficult to obtain in England, but a description of
+them may be interesting.
+
+
+=East Indian Varnishes.=--The Sylhet varnish is composed of two parts of
+the juice of the bhela (the tree which bears the marking nuts of India),
+and one part of the juice of the jowar. The articles varnished with it
+at Sylhet are of the most beautiful glossy black; and it seems equally
+fitted for varnishing iron, leather, paper, wood, or stone. It has a
+sort of whitish-grey colour when first taken out of the bottle, but in a
+few minutes it becomes perfectly black by exposure to the air. In the
+temperature of this country it is too thick to be laid on alone; but it
+may be rendered more fluid by heat. In this case, however, it is clammy,
+and seems to dry very slowly. When diluted with spirits of turpentine,
+it dries more quickly; but still with less rapidity than is desirable.
+
+The _tsitsi_, or Rangoon varnish, is less known than the Sylhet varnish.
+It is probably made from the juice of the bhela alone. It appears to
+have the same general properties as the Sylhet varnish, but dries more
+rapidly. The varnish from the _kheeso_, or varnish-tree, may be the same
+as the Rangoon varnish, but is at present considered to be very
+different. The kheeso grows particularly in Kubboo, a valley on the
+banks of the Ningtee, between Munnipore and the Burman empire. It
+attains to such a large size, that it affords planks upwards of three
+feet in breadth, and in appearance and grain is very like mahogany. A
+similar tree is found in great abundance and perfection at Martaban.
+
+A poisonous vapour exhales from several of the Indian varnishes,
+especially from that of Sylhet, and is apt to produce over the whole
+skin inflammations, swellings, itchings, and pustules, as if the body
+had been stung by a number of wasps. Its effects, however, go off in a
+few hours. As a preventative the persons who collect the varnish, before
+going to work, smear their faces and hands with greasy matter to prevent
+the varnish poison coming into contact with their skin.
+
+
+
+
+CHAPTER VII.
+
+_GENERAL INSTRUCTIONS._
+
+
+=Remarks on Polishing.=--Amateurs at French polishing will be more
+successful on a large surface than a small one.
+
+When polishing, the rubber-cloth should be changed occasionally, or the
+brightness will not remain when finished.
+
+A most efficacious improver of many kinds of woods is raw linseed-oil
+mixed with a little rectified spirits of turpentine.
+
+French polish can be tinted a light-red with alkanet-root, and a
+dark-red with dragon's blood.
+
+A good Turkey sponge is capable of spreading either stain or varnish
+more smoothly than a camel's-hair brush on a flat surface.
+
+The sub-nitrate of bismuth mentioned on p. 12 is beginning to supersede
+oxalic acid for bleaching processes.
+
+Thin panels for doors should be securely tacked down to a level board,
+and polished with a large round flannel rubber having a very flat sole.
+Fret-work panels should have all the edges entirely finished with
+varnish before they undergo the above operation. To get a good polish
+upon a full-fret panel is considered by polishers to be the most
+difficult part in the work, on account of the extreme delicacy and
+frangibility of the work and the great carefulness required.
+
+Soft spongy wood may be satiated by rubbing a sponge well filled with
+polish across the grain until it becomes dry.
+
+In polishing a very large surface, such as a Loo-table top or a wardrobe
+end, it is best to do only half at a time, or if a large top a quarter
+only.
+
+The approved method of treating dining-table tops is to well body-in
+with French polish, after which thoroughly glass-paper down with fine
+paper, and then use the oil polish (see page 87).
+
+Immediately after using a rubber, it should be kept in an air-tight tin
+canister, where it will always remain fresh and fit for use.
+
+
+=The Polishing Shop.=--A few words as to the polishing shop may be
+acceptable to those who possess ample room and desire the best results.
+
+First in order is the location and arrangement of the finishing rooms.
+Preference is to be given to the upper rooms of a building for several
+reasons, among which may be named the securing of better light, greater
+freedom from dust, and superior ventilation.
+
+A good light in this, as in many other arts, is a very important matter,
+and by a good light we mean all the light that can be obtained without
+the glare of the direct rays of the sun. Light from side windows is
+preferable to that from skylights for three reasons: (1) Skylights are
+very liable to leakage; (2) they are frequently, for greater or less
+periods, covered with snow in winter; (3) the rays of the sun
+transmitted by them in summer are frequently so powerful as to blister
+shellac or varnish.
+
+Good ventilation is at all times of importance, and especially so in
+summer, both as tending to dry the varnish or shellac more evenly and
+rapidly, and as contributing to the comfort of the workmen. The latter
+consideration is of importance even as a matter of economy, as men in a
+room the atmosphere of which is pleasant and wholesome will feel better
+and accomplish more than they could do in the close and forbidding
+apartments in which they sometimes work.
+
+Any suggestion in reference to freedom from dust, as a matter to be
+considered in locating rooms for this business, would seem to be
+entirely superfluous, as it is clear that there is hardly any
+department of mechanical work which is so susceptible to injury from
+dust as the finishing of furniture, including varnishing and polishing.
+
+Finishing rooms may be arranged in three departments. The first should
+include the room devoted to sand-papering and filling. These processes,
+much more than any other part of furniture polishing, produce dirt and
+dust, and it is plain that the room devoted to them should be so far
+isolated from the varnishing room as not to introduce into it these
+injurious elements.
+
+Another room should be appropriated to the bodying-in, smoothing and
+rubbing-down processes. The third room is for spiriting and varnishing,
+or the application of the final coats of varnish, which is the most
+important of all the processes in finishing. It requires a very light
+and clean room, and a greater degree of heat than a general workroom. It
+should, as nearly as possible, be uniform, and kept up to _summer heat_;
+in no case ought the temperature to fall below fifty nor rise higher
+than eighty-five degrees Fahrenheit while the varnishing process is
+going on. Varnishing performed under these circumstances will be more
+thorough in result, have a brighter appearance and better polish, than
+if the drying is slow and under irregular temperature. For drying work,
+the best kind of heat is that from a stove or furnace.
+
+Steam heat is not so good for two reasons: (1), it is too moist and
+soft, causing the work to sweat rather than to dry hard, and (2), the
+temperature of a room heated by steam is liable to considerable
+variation, and especially to becoming lower in the night. This _fire
+heat_ is as necessary for the varnishing room in damp and cloudy weather
+in summer as it is in winter. At all seasons, and by night as well as by
+day, the heat should be as dry as possible, and kept uniformly up to
+summer heat, by whatever means this result is secured. Varnished work,
+after receiving the last coat, should be allowed to remain one day in
+the varnishing room. It may then be removed into the general workroom.
+
+A remark may be proper here, viz., that there is sometimes a failure to
+secure the best and most permanent results from not allowing sufficient
+time for and between the several processes. An order is perhaps to be
+filled, or for some other reason the goods are "rushed through" at the
+cost of thoroughness and excellence of finish.
+
+The following suggestion is made by way of caution in reference to the
+disposal of oily rags and waste made in the various processes of
+finishing. These articles are regarded as very dangerous, and are
+frequently the cause of much controversy between insurance companies and
+parties who are insured. The best way to dispose of this waste is to put
+it into the stove and burn it as fast as it is produced. If this rule
+is strictly adhered to there will be no danger of fire from this source.
+All liquid stock should be kept in close cans or barrels, and as far
+from the fire as possible.
+
+
+
+
+CHAPTER VIII.
+
+_ENAMELLING._
+
+
+The process of enamelling in oil varnishes as applied to furniture must
+be understood as a smooth, glossy surface of various colours produced by
+bodies of paint and varnish skilfully rubbed down, and prepared in a
+peculiar way so as to produce a surface equal to French polish. Ornament
+can be added by gilding, etc., after the polished surface is finished.
+
+We will begin with the white or light-tinted enamel. The same process
+must be pursued for any colour, the only difference being in the
+selection of the materials for the tint required to be produced.
+
+It should be observed that enamelling requires the exercise of the
+greatest care, and will not bear hurrying. Each coat must be allowed
+sufficient time for the hardening, and the rubbing down must be
+patiently and gently done; heavy pressure will completely spoil the
+work.
+
+
+=Materials.=--The materials used for the purpose above named are: white
+lead ground in turpentine and the best white lead in oil; a clear,
+quick, and hard-drying varnish, such as the best copal, or the varnishes
+for enamel manufactured by Mr. W. Urquhart, 327, Edgware Road, W.; or
+white coburg and white enamel varnish, ground and lump pumice-stone, or
+putty-powder, great care being taken in the selection of the
+pumice-stone, as the slightest particle of grit will spoil the surface;
+and rotten-stone, used either with water or oil.
+
+
+=Tools.=--The tools required are several flat wooden blocks, of various
+sizes and forms, suitable for inserting into corners and for
+mouldings--these must be covered with felt on the side you intend to
+use, the felt best adapted for the purpose being the white felt, from a
+quarter to half an inch in thickness, which can be obtained of Messrs.
+Thomas Wallis & Co., Holborn Circus, or at the woollen warehouses; two
+or three bosses (made similar to polish rubbers) of cotton-wool, and
+covered with silk (an old silk handkerchief makes capital coverings);
+wash or chamois leather, and a good sponge.
+
+
+=Mode of Operation.=--If the wood is soft and porous it is best to
+commence with a coating of size and whiting applied in a warm state,
+which is allowed to dry; it is then rubbed down with glass-paper, and
+two coats of common paint given, mixed in the usual way and of the same
+colour as you intend to finish with. In practice this is found to be
+best; after these two coats are thoroughly dry, mix the white-lead
+ground in turps, with only a sufficient quantity of varnish to bind it,
+thinning to a proper consistency with turps. It is as well to add a
+little of the ordinary white-lead ground in oil, as it helps to prevent
+cracking. Give the work four or five coats of this, and allow each coat
+to dry thoroughly. When it is hard and ready for rubbing down, commence
+with a soft piece of pumice-stone and water, and rub just sufficient to
+take off the roughness. Now use the felt-covered rubbers and ground
+pumice-stone, and cut it down, working in a circular manner. The
+greatest care is required to obtain a level surface free from scratches.
+
+After the work is well rubbed down, if it should appear to be
+insufficiently filled up, or if scratched, give it two more coats, laid
+on very smoothly, and rub down as before. If properly done, it will be
+perfectly smooth and free from scratches. Wash it well down, and be
+careful to clean off all the loose pumice-stone. Then mix flake-white
+from the tube with either of the above-named varnishes, till it is of
+the consistency of cream. Give one coat of this, and when dry give it
+another, adding more varnish. Let this dry hard, the time taken for
+which will of course depend upon the drying qualities of the varnish;
+some will polish in eight or nine days, but it is much the best to let
+it stand as long as you possibly can, as the harder it is, the brighter
+and more enduring will be the polish. When sufficiently hard, use the
+felt, and very finely-ground pumice-stone and water; with this cut down
+till it is perfectly smooth; then let it stand for a couple of days, to
+harden the surface.
+
+
+=Polishing.=--In commencing to bring up a polish, first take
+rotten-stone, either in oil or water; use this with the felt rubber for
+a little while, then put some upon the surface of the silk-covered boss,
+and commence to rub very gently in circular strokes; continue this till
+there is a fine equal surface all over. The polish will begin to appear
+as you proceed, but it will be of a dull sort. Clean off: if the
+rotten-stone is in oil, clean off with dry flour; if in water, wash off
+with sponge and leather, taking care that you wash it perfectly clean
+and do not scratch.
+
+You will now, after having washed your hands, use a clean damp chamois
+leather, holding it in the left hand, and using the right to polish
+with, keeping it clean by frequently drawing it over the damp leather.
+With the ball of the right hand press gently upon the work, and draw
+your hand sharply, forward or towards you; this will produce a bright
+polish, and every time you bring your hand forward a sharp shrill sound
+will be heard similar to rubbing on glass. Continue this till the whole
+surface is one bright even polish. It will be some time before you will
+be able to do this perfectly, especially if the skin is dry or hard, as
+it is then liable to scratch the work. A smooth, soft skin will produce
+the best polish.
+
+For the interior of houses, the "Albarine" enamel manufactured by the
+Yorkshire Varnish Company, of Ripon, is recommended. This article
+combines in itself a perfectly hard solid enamel of the purest possible
+colour; and for all interior decorations, where purity of colour and
+brilliancy of finish are desired, it is universally admitted to be the
+most perfect article of the kind hitherto introduced to the trade. It is
+applied in the same manner as ordinary varnish.
+
+_Another Process._--The preceding section describes the process of
+enamelling by oil varnishes, and the directions referring to the
+polishing will be found of value for the "polishing up" on painted
+imitations of woods or marbles. There is another process whereby an
+enamel can be produced upon furniture at a much cheaper rate than the
+preceding, and one too, perhaps, in which a polisher may feel more "at
+home." The work should first have a coating of size and whiting (well
+strained); this will act as a pore-filler. When dry, rub down with fine
+paper, after which use the felt-covered rubber and powdered
+pumice-stone, to remove all the scratches caused by the glass-paper and
+to obtain a smooth and good surface. Then proceed to make a solution for
+the enamel: first procure two ounces of common isinglass from the
+druggist's, and thoroughly dissolve it in about a pint of boiling water;
+when dissolved, stir in two ounces and a-half of subnitrate of
+bismuth--this will be found to be about the right quantity for most
+woods, but it can be varied to suit the requirements. With this give the
+work one coat, boiling hot; apply it with a soft piece of Turkey sponge,
+or a broad camel's-hair brush, and when dry cut down with powdered
+pumice-stone; if a second coat is required, serve in precisely the same
+manner. Then proceed to polish in the ordinary way with white polish.
+After wetting the rubber, sprinkle a small quantity of the subnitrate of
+bismuth upon it; then put on the cover, and work in the usual manner;
+continue this till a sufficient body is obtained, and after allowing a
+sufficient time for the sinking and hardening it can be spirited off.
+
+Enamelled furniture has had, comparatively speaking, rather a dull sale,
+but there is no class of furniture more susceptible of being made to
+please the fancy of the many than this. It can be made in any tint that
+may be required by the application of Judson's dyes, and the exercise of
+a little skill in the decoration will produce very pleasing effects.
+
+
+=Decorations.=--The decorations are usually ornaments drawn in gold. A
+cut-out stencil pattern is generally used, and the surface brushed over
+with a camel's-hair pencil and japanner's gold size, which can be
+obtained at the artist's colourman's, or, if preferred, can be made by
+boiling 4 ozs. of linseed-oil with 1 oz. of gum anime and a little
+vermilion. When the size is tacky, or nearly dry, gold powder or gold
+leaf is applied. The gold is gently pressed down with a piece of
+wadding, and when dry the surplus can be removed with a round
+camel's-hair tool. In all cases where gold has been fixed by this
+process it will bear washing without coming off, which is a great
+advantage.
+
+
+
+
+CHAPTER IX.
+
+_AMERICAN POLISHING PROCESSES_
+
+
+The method of polishing furniture practised by the American
+manufacturers differs considerably from the French polishing processes
+adopted by manufacturers in most European countries. This difference,
+however, is mostly compulsory, and is attributable to the climate. The
+intense heat of summer and the extreme cold of winter will soon render a
+French polish useless, and as a consequence numerous experiments have
+been tried to obtain a polish for furniture that will resist heat or
+cold. The writer has extracted from two American cabinet-trade journals,
+_The Cabinet-maker_ and _The Trade Bureau_, descriptions of the various
+processes now used in the States, which descriptions were evidently
+contributed by practical workmen. The following pages are not, strictly
+speaking, a mere reprint from the above-named journals, the articles
+having been carefully revised and re-written after having been
+practically tested; attention to them is, therefore, strongly
+recommended.
+
+In these processes the work is first filled in with a "putty filler,"
+and after the surface has been thoroughly cleaned it is ready for
+shellac or varnish. Second, a coating of shellac is next applied with a
+brush or a soft piece of Turkey sponge. This mixture is composed of two
+parts (by weight) of shellac to one of methylated spirits, but what is
+called "thin shellac" is composed of one part shellac to two of spirits.
+After the coating is laid on and allowed to dry, which it does very
+soon, it is rubbed carefully with fine flour glass-paper, or powdered
+pumice-stone--about four coats are usually given, each one rubbed down
+as directed. Third, when the surface has received a sufficient body, get
+a felt-covered rubber and apply rotten-stone and sweet oil in the same
+manner as you would clean brass; with this give the work a good rubbing,
+so as to produce a polish. Fourth, clean off with a rag and sweet oil,
+and rub dry; then take a soft rag with a few drops of spirit upon it,
+and vapour up to a fine polish. With these few preliminary remarks, the
+following will be easily understood.
+
+
+=Use Of Fillers.=--The cost of a putty filler consists chiefly in the
+time consumed in applying it. In the matter of walnut-filling much
+expense is saved in the processes of coating and rubbing if the pores of
+the wood be filled to the surface with a substance that will not shrink,
+and will harden quickly. The time occupied in spreading and cleaning a
+thin or fatty mixture of filler, or a stiff and brittle putty made fresh
+every day, is about the same, and while the thin mixture will be subject
+to a great shrinkage, the putty filler will hold its own. It will thus
+be seen that a proper regard to the materials used in making fillers,
+and the consistency and freshness of the same, form an important element
+in the economy of filling.
+
+A principal cause of poor filling is the use of thin material. By some a
+putty-knife is used, and the filling rubbed into the surfaces of
+mouldings with tow, while others use only the tow for all surfaces,
+mostly, however, in cases of dry filling. In the use of the wet filler,
+either with a knife or with tow, workmen are prone to spread it too thin
+because it requires less effort, but experience shows that the greatest
+care should always be taken to spread the putty stiff and thick,
+notwithstanding the complaints of workmen. In fact, this class of work
+does not bring into play so much muscle as to warrant complaints on
+account of it. Nor can there be any reasonable excuse for taking a
+longer time to spread a stiff filler than a thin filler.
+
+Good results are not always obtained by the use of thick fillers,
+because the putty is spread too soon after the application of the first
+coat of oil, which liquid should be quite thin, and reduced either with
+benzine or turpentine, so that when the putty is forced into the pores
+the oil already in them will have the effect of thinning it. As an
+illustration of the idea meant here to be conveyed, we will suppose a
+quantity of thick mud or peat dumped into a cavity containing water, and
+a similar quantity of the same material dumped into another cavity
+having no water; the one fills the bottom of the cavity solid, while the
+other becomes partly liquid at the bottom, and must of necessity shrink
+before it assumes the solidity of the former. Hence it appears that work
+to be filled should be oiled and allowed to stand some time before
+receiving the filler, or until the oil has been absorbed into the pores.
+
+The preparatory coating should not be mixed so as to dry too quickly,
+nor allowed to stand too long before introducing the putty, for in this
+case the putty when forced along by the knife will not slip so easily as
+it should.
+
+The cost of rubbing and sand-papering in the finishing process is very
+much lessened if the cleaning be thorough, and if all the corners and
+mouldings be scraped out, so that pieces of putty do not remain to work
+up into the first coat of shellac, or whatever finish may be used as a
+substitute for shellac.
+
+Another important feature in hard filling is to let the work be well
+dried before applying the first coat of finish. One day is not
+sufficient for the proper drying of putty fillers, and if in consequence
+of insufficient drying a part of the filling washes out, it is so much
+labour lost. As a safeguard against washing out, these fillers should be
+mixed with as much dryer or japan as the case warrants, for it
+frequently occurs that work must be finished, or go into finish, the day
+following the filling, whether it be dry or not.
+
+By observing the main facts here alluded to, good filling may always be
+obtained, and at a cost not exceeding that of poor work.
+
+For the light woods, including ash, chestnut, and oak, the filling is
+similar to that used in walnut, except the colouring material, which, of
+course, must be slight, or just enough to prevent the whiting and
+plaster from showing white in the pores. This colouring may consist of
+raw sienna, burnt sienna, or a trifle raw, or umber; one of these
+ingredients separate, or all three combined, mixed so as to please the
+fancy and suit the prevailing style. The colouring may be used with a
+dry filling, although a wet filling is more likely to give a smooth
+finish and greater satisfaction, and the colour of the filler can be
+seen better in the putty than in the dry powder.
+
+Upon cheap work a filler should be used that requires the least amount
+of labour in its application. For this purpose liquid fillers, like
+japan, are suitable. If, however, a fine finish on fine goods is
+required, the putty compositions of various mixtures are the more
+appropriate. The secret of the process of filling consists in the
+mixing of the compounds and the method of using them. A liquid filler
+or a japan simply spread over the work in one or two coats can hardly be
+called filling, yet this will serve the purpose very well for cheap
+furniture.
+
+Thick compositions or putty fillers are composed of whiting and plaster,
+or similar powders having little or no colour. This material is mixed
+with oil, japan, and benzine, with a sufficient quantity of colouring
+matter to please the fancy. The value of these fillers is in proportion
+to their brittleness or "shortness," as it is termed, and, to give them
+this quality, plaster is used and as much benzine or turpentine as the
+mixture will bear without being too stiff or too hard to clean off.
+Sometimes a little dissolved shellac is used to produce "shortness."
+This desirable feature of a filler is best effected by mixing a small
+quantity of the material at a time. Many workmen mistakenly mix large
+batches at a time with a view of securing uniformity of colour, and this
+is one cause why such fillers work tough and produce a poor surface. An
+oil mixture soon becomes fatty and tough, and must be reduced in
+consistency when used, as it is apt when old to "drag" and leave the
+pores only partly filled. These fillers should be mixed fresh every day,
+and allowed to stiffen and solidify in the wood rather than out of it.
+
+The surface of a pore is the largest part of it, and it is desirable to
+fill it to a level as nearly as possible. This is done by using the
+filler thick or stiff.
+
+
+=Making Fillers.=--In making "fillers," a quantity of the japan which is
+used in the ingredients can be made at one time, and used from as
+occasion may require. It is made in the following manner:
+
+_Japan of the Best Quality._--Put 3/4 lb. gum shellac into 1 gall.
+linseed-oil; take 1/2 lb. each of litharge, burnt umber, and red-lead,
+also 6 oz. sugar of lead. Boil in the mixture of shellac and oil until
+all are dissolved; this will require about four hours. Remove from the
+fire, and stir in 1 gall. of spirits of turpentine, and the work is
+finished.
+
+_Fillings for Light Woods._--Take 5 lb. of whiting, 3 lb. calcined
+plaster (plaster of Paris), 1/2 gall. of raw linseed-oil, 1 qt. of
+spirits of turpentine, 1 qt. of brown japan, and a little French yellow
+to tinge the white. Mix well, and apply with a brush; rub it well with
+excelsior or tow, and clean off with rags. This thoroughly fills the
+pores of the wood and preserves its natural colour.
+
+_Another for Light Woods._--Take 10 lb. of whiting, 5 lb. of calcined
+plaster, 1 lb. of corn starch, 3 oz. calcined magnesia, 1 gall. of raw
+linseed-oil, 1/2 gall. spirits of turpentine, 1 qt. of brown japan, 2
+oz. French yellow. Mix well, and apply with brush; rub in well with
+excelsior or tow, and clean off with rags.
+
+_For Mahogany or Cherry Wood._--Take 5 lb. of whiting, 2 lb. of calcined
+plaster, 11/2 oz. dry burnt sienna, 1 oz. Venetian red, 1 qt. of boiled
+linseed-oil, 1 pt. of spirits of turpentine, and 1 pt. of brown japan.
+Mix well, apply with brush, and rub well in with excelsior or tow. Clean
+off with rags dry.
+
+_For Oak Wood._--Take 5 lb. of whiting, 2 lb. calcined plaster, 1 oz.
+dry burnt sienna, 1/2 oz. of dry French yellow, 1 qt. raw linseed-oil, 1
+pt. benzine spirits, and 1/2 pt. white shellac. Mix well, apply with
+brush, rub in with excelsior or tow, and clean off with rags.
+
+_For Rosewood._--Take 6 lb. of fine whiting, 2 lb. of calcined plaster,
+1 lb. of rose-pink, 2 oz. of Venetian red, 1/2 lb. of Vandyke brown, 1/2
+lb. of Brandon red, 1 gall. of boiled linseed-oil, 1/2 gall. of spirits
+of turpentine, 1 qt. of black japan. Mix well together, apply with
+brush, rub well in with tow, and clean off with rags.
+
+_For Black Walnut_ (1).--For medium and cheap work. Take 10 lb. of
+whiting, 3 lb. dry burnt umber, 4 lb. of Vandyke brown, 3 lb. of
+calcined plaster, 1/2 lb. of Venetian red, 1 gall. of boiled
+linseed-oil, 1/2 gall. of spirits of turpentine, 1 qt. of black japan.
+Mix well and apply with brush; rub well with excelsior or tow, and clean
+off with rags.
+
+_For Black Walnut_ (2).--An improved filling, producing a fine
+imitation of wax finish, may be effected by taking 5 lb. of whiting,
+with 1 lb. of calcined plaster, 6 oz. of calcined magnesia, 1 oz. of dry
+burnt umber, 1 oz. of French yellow to tinge the white. Add 1 qt. of raw
+linseed-oil, 1 qt. of benzine spirits, 1/2 pt. of very thin white
+shellac. Mix well, and apply with a brush; rub well in, and clean off
+with rags.
+
+_An Oil-Colour for Black Walnut_ (3), to be used only on first-class and
+custom work.--Take 3 lb. of burnt umber ground in oil, 1 lb. of burnt
+sienna ground in oil, 1 qt. of spirits of turpentine, 1 pt. of brown
+japan. Mix well and apply with a brush. Sand-paper well; clean off with
+tow and rags. This gives a beautiful chocolate colour to the wood.
+
+Numerous compositions are in the market for filling the pores of wood,
+and in this connection particular attention has been given to walnut,
+for the reason that this wood is used in large quantities in the
+furniture industry, and is nearly, if not quite, as porous as any other
+of the woods used.
+
+A variety of walnut fillings have been recommended to the trade in order
+to meet the demand consequent upon the different grades of finish and
+the method of obtaining the finish, so that it would be difficult to
+pronounce as to the superiority of any one filling for general purposes.
+In treating this subject, attention should be given to the necessities
+for the use of filling, so that each one may determine for himself the
+kind of composition best adapted for the work in hand, and the best
+method of applying it.
+
+
+=Finishing.=--Having described the methods of making and applying the
+"fillings," we will now describe the mode of finishing, and begin with
+the "dead-oil finish." We can remember when a satisfactory oil-finish
+was produced either with a good quality of japan or a fair quality of
+spirits. These materials are recommended to be used by inexperienced
+workmen and those not familiar with the mixing of the various grades of
+japan and varnish with oil, turpentine, benzine, etc. This method of
+oil-finish, too, is scarcely inferior to the shellac or spirit-varnish
+method, and it is cheaper. When the best finish is desired, a sufficient
+number of coats to fill the pores of wood to a level are required, and
+then the whole surface should be subjected to the rubbing process. The
+use of these fillers provides an oil-finish in a simplified form for
+those who are not aware of the difference between hard and soft gum
+compositions as a base for rubbing. In fact, the rubbing process
+constitutes a fine oil-finish, and requires a hard gum, whether it be of
+japan, varnish, or shellac.
+
+The use of varnish or its substitute as a filler and finish is more
+frequent than the use of shellac, and for cheap work it is equally good.
+The surface produced by a hard gum composition must be smooth and dead,
+or but slightly glossed, so as to admit of the pores being filled full
+or to a level. It may be added that a coat or any number of coats of the
+composition referred to above is substantially a filling, and the
+quality of finish depends upon the number of coats, together with the
+amount of rubbing applied.
+
+Thus far we have simply called attention to the best quality of
+oil-finish and the manner of producing it. Possibly three-fourths of all
+wood-finishing, particularly walnut-finishing, is several degrees below
+the best quality. In fact, oil-finish may imply only one coat of any
+composition that will dry, while two coats may be regarded as fair, and
+three coats a very good quality of finish. For the class of finish not
+rubbed down with pumice-stone and water, oil-varnish would be out of
+place on account of its gloss; hence shellac, being in composition
+similar to japan, is the better material, because of its dull appearance
+or lack of gloss as compared with shellac.
+
+In addition to the liquid fillers already mentioned, there is a putty or
+powder filling used for cross-grained woods, or such woods as have a
+deep pore. This filling is forced into the wood previous to the
+application of the other finishing compounds, with the use of which it
+in no way interferes. On the contrary, it economises the use of the
+liquid fillers, and, while constituting a part of an oil-finish, is also
+a finish wholly independent of the other methods mentioned--that is to
+say, the same results can be obtained by the use of either one, although
+the putty or powder filling is attended with greater expense both as to
+time and material. The hard filling is generally used on walnut, ash,
+and all coarse-grained woods.
+
+With regard to oil-finishes, viz., spirit-varnish or oil-varnish,
+shellac is thought by many to be the best for fine work; but others
+think differently. We may say of shellac that it will finish up into any
+degree of polish, and while it will not retain a French polish long in
+this climate, it will replenish easier and cheaper than any other
+finish, and continue to improve under each application. For a common
+finish, however, oil preparation is as good as shellac, and even for a
+fine finish it is only second to shellac, if made of a hard gum. On
+common finish, too, the oil will wear better than shellac in stock or on
+storage, so far as preserving its freshness is concerned.
+
+The cost of oil-finish is governed chiefly by the amount of labour
+expended on it. A suite of walnut furniture can be well rubbed with
+sand-paper in two hours, or even less; while two weeks could be
+profitably employed in rubbing another suite with pumice and water.
+
+
+=Black Walnut Finishing.=--The fashionable finish for black walnut work,
+particularly chamber sets, is what is known to the trade as the
+"dead-oil finish." It is admired, perhaps, because it has a gloss,
+rather than a shine of the varnish stamp. There is no more labour
+required upon it than upon a bright finish, but the process of
+manipulation is different, and harder to the fingers.
+
+It should be premised that the walnut work of the day bears upon its
+surface, to a greater or less extent, raised panels covered with French
+burl veneer. And upon this fact largely depends the beauty of the
+production. And the endeavour is to so finish the article that there
+shall be a contrast between the panel and the groundwork on which it is
+placed. In other words, the former should be of a light colour, while
+the latter is of a darker shade. In that view the palest shellac should
+be used on the panels, and darker pieces, liver coloured, etc., on the
+body of the work. The darker grades of shellac are the cheaper, and will
+answer for the bulk of the work, but the clearest only for the panels.
+
+In commencing to finish a job direct from the cabinet-maker's hand,
+rough and innocent of sand-paper, first cover the panels with a coat of
+shellac to prevent the oil in the filling from colouring them dark.
+Next, cover the body of the work with a wood filling composed of whiting
+and plaster of Paris, mixed with japan, benzine, and raw linseed-oil, or
+the lubricating oil made from petroleum; the whole covered with umber,
+to which, in the rare cases when a reddish shade is wanted, Venetian
+red is also added. This filling is then rubbed off with cloths, and by
+this process tends to close up the grain of the wood and produce an even
+surface. More or less time should be allowed after each of the several
+steps in the finishing process for the work to dry and harden, though
+much less is required in working with shellac than with varnishes
+composed of turpentine, oil, and gums. But the time that should be
+allowed is often lessened by the desire to get the work through as soon
+as possible, so that no standard can be set up as to the number of hours
+required between each of the several processes. It would be well if
+twelve hours intervened, but if work to which ten days could well be
+devoted must be hurried through in three, obviously the processes must
+follow each other in a corresponding haste.
+
+A coating of shellac is then given the whole work, light on the panels
+and dark on the body work, and when it has dried and hardened, which it
+does very soon, it may be rubbed down. This process of "rubbing down"
+should be done evenly and carefully, so as not to rub through the
+shellac at any point, and be done with the finer grades of sand-paper
+for the cheaper class of work, particularly at first, but at a later
+period of the process, and for the better class of articles in all
+cases, hair-cloth should be used, the material for the "rubbing down"
+being pumice-stone moistened with raw linseed-oil for the best work, and
+the lubricating oil, before mentioned, for cheaper work, or the covered
+parts of the better grades. This rubbing down involves labour, wear of
+fingers and finger-nails, and is carried on with an ordinary bit of
+hair-cloth, the smooth surface next the wood, and not made in any
+particular shape, but as a wad, ball, or otherwise. In the corners and
+crevices where the hair-cloth will not enter it will be necessary to use
+sand-paper of the finest grades, and worn pieces only.
+
+Three coats of shellac are put on, followed each time by this
+rubbing-down process, each one giving the work a smoother feeling and a
+more perfect appearance. Afterwards, to complete the whole, a coating of
+japan thinned with benzine is applied, which gives to the work a clean
+appearance and the dead glossy finish.
+
+There is this objection to the above style of finish, that the japan
+catches all the dust which touches it, and holds it permanently, so that
+many of the best workmen will not have work finished in this way for
+their own private houses, preferring the brighter look given by shellac
+and varnish without rubbing down the last coat, believing that the work
+can be kept much cleaner.
+
+
+=Finishing Veneered Panels, etc.=--The large oval panels of desks, etc.,
+covered with French veneer, are generally taken out and finished by
+themselves. The process is similar to that above given, with successive
+coats of shellac and varnish, and the oil and pumice-stone rubbing down;
+but the final part of this latter process is a rubbing down with
+rotten-stone; then the merest trifle of sweet-oil is applied all over
+the surface and wiped off. (See Rosewood, etc., farther on.)
+
+_For Light Woods (Dead Finish)._--Apply two or three coats of white
+shellac; rub down with pumice and raw linseed-oil, and clean off well
+with rags; use varnish-polish on the panels.
+
+_Another._--Finish as in the previous recipe. For a flowing coat of
+varnish-finish apply one flowing coat of light amber varnish. If a
+varnish-polish is desired, apply three coats of Zanzibar polishing
+varnish. Rub down and polish, and the result will be a splendid finish.
+
+_Mahogany or Cherry Wood._--For shellac _dead finish_ apply two coats of
+yellow shellac. Rub down with pumice and raw linseed-oil. If a
+varnish-finish is desired, apply a flowing coat of light amber varnish
+or shellac thus rubbed. The panels should receive two coats of Zanzibar
+polishing varnish.
+
+_Oak._--For a _dead finish_ give three coats of shellac, two-thirds of
+white and one-third of yellow, mixed. Rub down with pumice and raw
+linseed-oil. For a cheap varnish-finish give one flowing coat of light
+amber varnish in the shellac, rubbed as directed. Varnish-polish the
+panels.
+
+_Rosewood, Coromandel, or Kingwood (a Bright Finish)._--Apply two thin
+coats of shellac, sand-papering each coat; then apply three or four
+coats of Zanzibar polishing varnish, laying it on thin, and giving it
+sufficient time to dry thoroughly. When it is perfectly hard, rub down
+with pumice and water. Polish with rotten-stone to a fine lustre, clean
+up with sweet-oil, and vapour up the oil with a damp alcohol rag. The
+result is a splendid mirror-like polish. This is the method employed in
+polishing pianofortes in America.
+
+_Walnut._--For a cheap finish, apply one coat of yellow shellac. When
+dry, sand-paper down. Apply with brush; rub in well; clean off with
+rags. This gives a very fair finish.
+
+For a medium _dead finish_ apply two or three coats of yellow shellac.
+When dry, rub down with pumice and raw linseed-oil; clean up well;
+varnish-polish the panels.
+
+For _finish._ Before using the above filling, give the work one coat of
+white shellac. When dry, sand-paper down, and apply the above filling.
+Give two coats of white shellac; rub down with pumice and raw
+linseed-oil; clean up well with brown japan and spirits of turpentine,
+mixed. Wipe off. This is a good imitation of wax-finish; it is
+waterproof, and will not spot as wax-finish does. The panels are to be
+varnished-polished. This is to be used with the improved filling No. 2.
+
+For _finish._ Apply three coats of yellow shellac; rub down with pumice
+and raw linseed-oil; clean off well. Varnish-polish the panels. Use this
+with the oil colour No. 3.
+
+
+=Finishing Cheap Work.=--_With One Coat of Varnish._--Give the work a
+coat of boiled linseed-oil; immediately sprinkle dry whiting upon it,
+and rub it well in with tow all over the surface. The whiting absorbs
+the oil and completely fills the pores of the wood. For black walnut add
+a little dry burnt umber. For mahogany or cherry add a little Venetian
+red, according to the colour of the wood. The application can be made to
+turned work while in motion in the lathe. Clean off well with rags. The
+work can then be finished with a single coat of varnish, and for cheap
+work makes a very good finish.
+
+For varnishing large surfaces, a two-inch oval varnish brush is to be
+used first to lay out the varnish, and then a two-inch flat badger
+flowing-brush for a softener. The latter lays down moats and bubbles
+left by the large brush. A perfectly smooth glass-like surface is thus
+obtained. When not in use, these tools should be put into a pot
+containing raw linseed-oil and spirits of turpentine. This keeps them in
+a better working condition than if they are kept in varnish, making them
+clean and soft. Standing in varnish they congeal and become hard as the
+spirit evaporates from the varnish. For shellacing a large surface use a
+two-inch bristle brush; for small work, such as carvings and mouldings,
+use a one-and-a-half inch flat brush. These brushes when not in use
+should be taken from the various pots and deposited in an earthen pot
+sufficiently large to hold all the shellac brushes used in the shop. Put
+in enough of raw linseed-oil and thin shellac to cover the bristles of
+the brushes. Kept in this manner, they will remain clean and elastic,
+and will wear much longer.
+
+_Wax Finishing._--Take 1/2 gall. of turpentine, 11/2 lb. yellow
+beeswax, 1 lb. white beeswax, 1/2 lb. white rosin. Pulverise the rosin,
+and shave the wax into fine shavings. Put the whole into the turpentine,
+and dissolve it cold. If dissolved by a fire-heat, the vitality of the
+wax is destroyed. When it is thoroughly dissolved, mix well and apply
+with a stiff brush. Rub well in, and clean off with rags. When dry, it
+is ready for shellac or varnish as may be desired.
+
+_A Varnish Polish._--Take 10 oz. gum shellac, 1 oz. gum sandarach, 1
+drachm Venice turpentine, 1 gall. alcohol. Put the mixture into a jug
+for a day or two, shaking occasionally. When dissolved it is ready for
+use. Apply a few coats. Polish by rubbing smooth.
+
+For the commonest kind of work in black walnut a very cheap polish can
+be made in the following manner: Take 1 gall. of turpentine, 2 lb.
+pulverised asphaltum, 1 qt. boiled linseed-oil, 2 oz. Venetian red. Put
+the mixture in a warm place and shake occasionally. When it is
+dissolved, strain and apply to the wood with a stiff brush. Rub well
+with cloth when dry. Then take 1 pt. of thin shellac, 1/2 pt. boiled
+linseed-oil. Shake it well before using. Apply with cloth, rubbing
+briskly, and you will have a fine polish.
+
+_With Copal or Zanzibar Varnish._--As a substitute for filling, the wood
+may receive one coat of native coal-oil, thinned with benzine-spirits;
+then apply one coat of shellac, and follow with varnish, as desired. The
+time is not far distant when manufacturers must and will use varnish for
+the finishing of all kinds of furniture on account of the high price of
+shellac. Furniture finished in the last-named method may be rubbed with
+either water or oil. Water has a tendency to harden varnish, while oil
+softens it. If water is used there will be a saving of oil and rags. In
+the other case shellac, when rubbed with oil, should be cleaned with
+japan. This removes the greasy and cloudy appearance which is left after
+the rubbing with oil, and the work will have a clean, dry, and brighter
+appearance than otherwise.
+
+We suggest another idea for finishing black walnut for a cheap or a
+medium class of work. In the first place, fill the pores of the wood,
+and apply one thin coat of shellac to hold the filling in the pores of
+the wood. Let this stand one day; sand-paper down with fine paper, then
+with a brush apply a coat of coach japan. Rub well, and clean off with
+rags. Let this stand one day to dry, then, with some sand-paper that has
+been used before, take off the moats from the japan. Go over the whole
+surface with a soft rag saturated with japan; wipe and clean off
+carefully, and the job is finished. This, though a cheap finish, is a
+good one for this class of work.
+
+We give one more method of finishing black walnut, that is, with boiled
+linseed-oil only, and there is no other way of obtaining a genuine
+oil-finish. Sand-paper the wood down smoothly; apply a coat of boiled
+linseed-oil over the whole surface; sand-paper well, and clean up dry
+with rags; let it stand one day to dry, then apply one more coat of oil;
+rub well in with rags, but do not use sand-paper on this coat. Apply
+three, four, or more coats in the same way. When the work has received
+the last coat of oil and is dry, sand-paper down with old paper. Then
+clean up with the best coach japan with rags, and let the work stand one
+day to dry. The panels are to be varnish-polished the same as other
+wood. The work is then finished, and ready for the warerooms.
+
+This method takes a longer time than finishing with either varnish or
+shellac; but the cost is less both for materials and for labour, the
+workman being able to go over a greater surface in the same time. The
+work will stand longer, and the method gives a rich and close finish,
+bringing out the figure and rich colour of the wood better than in any
+other method of finishing. It does not cost so much as shellac finish;
+it only requires a little more time for drying between the coats of oil.
+In finishing in varnish or shellac, to get the body or surface for
+polishing three or four coats are frequently applied, which is liable to
+produce a dull cloudy appearance. For this reason, and having in view
+the high and increasing price of stock, it seems to us that this really
+superior method of finishing in oil must take the place of shellac and
+varnish-finish in good work.
+
+
+=Polishing Varnish.=--This is certainly a tedious process, and
+considered by many a matter of difficulty. The following is the mode of
+procedure: Put two ounces of powdered tripoli into an earthen pot or
+basin, with water sufficient to cover it; then, with a piece of fine
+flannel four times doubled, laid over a piece of cork rubber, proceed to
+polish your varnish, always wetting it well with the tripoli and water.
+You will know when the process is complete by wiping a part of the work
+with a sponge and observing whether there is a fair and even gloss.
+Clean off with a bit of mutton suet and fine flour. Be careful not to
+rub the work too hard, or longer than is necessary to make the face
+perfectly smooth and even. Some workmen polish with rotten-stone, others
+with putty-powder, and others with common whiting and water; but
+tripoli, we think, will be found to answer best.
+
+
+=An American Polish Reviver.=--Take of olive-oil 1 lb., of rectified oil
+of amber 1 lb., spirits of turpentine 1 lb., oil of lavender 1 oz.,
+tincture of alkanet-root 1/2 oz. Saturate a piece of cotton batting with
+this polish, and apply it to the wood; then, with soft and dry cotton
+rags, rub well and wipe off dry. This will make old furniture in private
+dwellings, or that which has been shop-worn in warerooms, look as well
+as when first finished. The articles should be put into a jar or jug,
+well mixed, and afterwards kept tightly corked.
+
+This is a valuable recipe, and is not known, the writer believes,
+outside of his practice.

+=Oil Polish.=--One quart of cold-drawn linseed-oil to be simmered (not
+boiled) for ten minutes, and strained through flannel; then add
+one-eighth part of spirits of turpentine: to be applied daily with soft
+linen rags, and rubbed off lightly; each time the oil is applied the
+surface should be previously washed with cold water, so as to remove any
+dirt or dust. This method of polishing is particularly useful for
+dining-table tops; it will in about six weeks produce a polish so
+durable as to resist boiling water or hot dishes, and be like a mirror
+for brilliancy.
+
+
+=Wax Polish.=--Eight ounces of beeswax, 2 oz. of resin, and 1/2 oz. of
+Venetian turpentine, to be melted over a slow fire; the mass, when quite
+melted, is poured into a sufficiently large stone-ware pot, and while it
+is still warm 6 oz. of rectified turpentine are stirred in. After the
+lapse of twenty-four hours the mass will have assumed the consistency
+of soft butter, and is ready for use. A small portion of the polish is
+taken up with a woollen rag and rubbed over the surface of the work--at
+first gently, then more strongly. When the polish is uniformly laid on,
+the surface is once more rubbed lightly and quickly with a fresh clean
+rag to produce a gloss.
+
+
+=Waterproof French Polish.=--Take 2 oz. gum benjamin, 1/2 oz. gum
+sandarach, 1/2 oz. gum anime, 11/2 oz. gum benzoin, and 1 pt. alcohol.
+Mix in a closely-stoppered bottle, and put in a warm place till the gums
+are well dissolved. Then strain off, and add 1/4 gill of poppy-oil.
+Shake well together, and it is ready for use.
+
+
+=A Varnish for Musical Instruments.=--Take one gallon of alcohol, 1 lb.
+gum sandarach, 1/2 lb. gum mastic, 2 lbs. best white resin, 3 lbs. gum
+benzoin; cut the gums cold. When they are thoroughly dissolved, strain
+the mixture through fine muslin, and bottle for use; keep the bottle
+tightly corked. This is a beautiful varnish for violins and other
+musical instruments of wood, and for fancy articles, such as those of
+inlaid work. It is also well adapted for panel-work, and all kinds of
+cabinet furniture. There is required only one flowing coat, and it
+produces a very fine mirror-like surface. Apply this varnish with a
+flat camel's-hair or sable brush. In an hour after application the
+surface is perfectly dry.
+
+
+=French Varnish for Cabinet-work.=--Take of shellac 11/2 oz. gum mastic
+and gum sandarach, of each 1/2 oz., spirit of wine by weight 20 oz. The
+gums to be first dissolved in the spirit, and lastly the shellac. This
+may be best effected by means of the water-bath. Place a loosely-corked
+bottle containing the mixture in a vessel of warm water of a temperature
+below the boiling point, and let it remain until the gums are dissolved.
+Should evaporation take place, an equal quantity to the spirit of wine
+so lost must be replaced till the mixture settles, then pour off the
+clear liquid for use, leaving the impurities behind; but do not filter
+it. Greater hardness may be given to the varnish by increasing the
+quantity of shellac, which may be done to the amount of one-twelfth of
+the lac to eleven-twelfths of spirit. But in this latter proportion the
+varnish loses its transparency in some degree, and must be laid on in
+very small quantities at a time.
+
+
+=Mastic Varnish.=--Mastic should be dissolved in oil of turpentine, in
+close glass vessels, by means of a gentle heat. This varnish is
+extensively used in transparencies, etc.
+
+
+=Cabinet-maker's Varnish.=--Take 5 lbs. very pale gum shellac, 7 oz. gum
+mastic, 1 gallon alcohol. Dissolve in a cold atmosphere with frequent
+stirring.
+
+
+=Amber Varnish.=--This is a most difficult varnish to make. It is
+usually prepared by roasting the amber and adding hot linseed-oil, after
+which turpentine can be mixed if required. But for a small quantity,
+dissolve the broken amber, without heat, in the smallest possible
+quantity of chloroform or pure benzine. Heat the linseed-oil, remove it
+from the fire, and pour in the amber solution, stirring all the time.
+Then add the turpentine. If not quite clear, heat again, using the
+utmost caution.
+
+
+=Colourless Varnish with Copal.=--To prepare this varnish the copal must
+be picked; each piece is broken, and a drop of rosemary-oil poured on
+it. Those pieces which, on contact with the oil, become soft are the
+ones used. The pieces being selected, they are ground and passed through
+a sieve, being reduced to a fine powder. It is then placed in a glass,
+and a corresponding volume of rosemary-oil poured over it; the mixture
+is then stirred for a few minutes until it is transformed into a thick
+liquor. It is then left to rest for two hours, when a few drops of
+rectified alcohol are added, and intimately mixed. Repeat the operation
+until the varnish is of a sufficient consistency; leave the rest for a
+few days, and decant the clear. This varnish can be applied to wood and
+metals (_Journal of Applied Chemistry_).
+
+
+=Seedlac Varnish.=--Wash 3 oz. of seedlac in several waters; dry it and
+powder it coarsely. Dissolve it in one pint of rectified spirits of
+wine; submit it to gentle heat, shaking it as often as convenient, until
+it appears dissolved. Pour off the clear part, and strain the remainder.
+
+
+=Patent Varnish for Wood or Canvas.=--Take 1 gallon spirits of
+turpentine, 21/4 lbs. asphaltum. Put them into an iron kettle on a
+stove, and dissolve the gum by heat. When it is dissolved and a little
+cool, add 1 pint copal varnish and 1 pint boiled linseed-oil. When
+entirely cool it is ready for use. For a perfect black add a little
+lamp-black.
+
+
+=Copal Varnish.=--Dissolve the copal, broken in pieces, in linseed-oil,
+by digestion, the heat being almost sufficient to boil the oil. The oil
+should be made drying by the addition of quick-lime. This makes a
+beautiful transparent varnish. It should be diluted with oil of
+turpentine; a very small quantity of copal, in proportion to the oil,
+will be found sufficient.
+
+
+=Carriage Varnish.=--Take 19 oz. gum sandarach, 91/2 oz. orange
+shellac, 121/2 oz. white resin, 18 oz. turpentine, 5 pints alcohol.
+Dissolve and strain. Use for the internal parts of carriages and similar
+purposes. This varnish dries in ten minutes.
+
+
+=Transparent Varnish.=--Take 1 gallon alcohol, 2 lbs. gum sandarach, 1/2
+lb. gum mastic. Place them in a tin can. Cork tight and shake
+frequently, placing the can in a warm place. When dissolved it is ready
+for use.
+
+
+=Crystal Varnish for Maps, etc.=--Mix together 1 oz. Canada balsam and 2
+oz. spirits of turpentine. Before applying this varnish to a drawing or
+a painting in water-colours the paper should be placed on a stretcher,
+sized with a thin solution of isinglass in water, and dried. Apply the
+varnish with a soft camel's-hair brush.
+
+
+=A Black Varnish.=--Mix a small quantity of gas-black with the brown
+hard varnish previously mentioned. The black can be obtained by boiling
+a pot over a gas-burner, so that it almost touches the burner, when a
+fine jet-black will form at the bottom, which remove and mix with the
+varnish, and apply with a brush.
+
+
+=A Black Polish= can be made in the same way: after wetting the rubber,
+just touch it with the black. Place the linen cover over, touch it with
+oil, and it is ready for work.
+
+
+=Varnish for Iron.=--Take 2 lbs. pulverised gum asphaltum, 1/4 lb. gum
+benzoin, 1 gallon spirits of turpentine. To make this varnish quickly,
+keep in a warm place, and shake often till it is dissolved. Shade to
+suit with finely-ground ivory-black. Apply with a brush. This varnish
+should be used on iron-work exposed to the weather. It is also well
+adapted for inside work, such as iron furniture, where a handsome polish
+is desired.
+
+
+=Varnish for Tools.=--Take 2 oz. tallow, 1 oz. resin; melt together, and
+strain while hot to remove the specks which are in the resin. Apply a
+slight coat on the tools with a brush, and it will keep off the rust for
+any length of time.
+
+
+=To Make Labels Adhere to a Polished Surface.=--Brush the back of a
+label over with thin varnish or polish, and press down with a soft rag;
+this must be done quickly, as the polish soon becomes dry. This is the
+way labels are put on pianofortes, and also the paper imitation of fancy
+woods on polished pine-work.
+
+
+=How to Remove French Polish or Varnish from Old Work.=--Cleaning off
+old work for re-polishing or varnishing is usually found difficult, and
+to occupy much time if only the scraper and glass-paper be used. It can
+be easily accomplished in a very short time by washing the surface with
+liquid ammonia, applied with a piece of rag; the polish will peel off
+like a skin, and leave the wood quite bare. In carvings or turned work,
+after applying the ammonia, use a hard brush to remove the varnish.
+Unadulterated spirits of wine used in a tepid state will answer the same
+purpose.
+
+
+=Colouring for Carcase Work.=--In the best class of cabinet-work all the
+inside work--such as carcase backs, shelves, etc.--is made of good
+materials, such as wainscot, soft mahogany, Havannah cedar, or American
+walnut; but for second-class work, pine or white deal is used instead,
+and coloured.
+
+The colouring matter used should match with the exterior wood. For
+mahogany take 1/2 lb. of ground yellow ochre to a quart of water, and
+add about a tablespoonful of Venetian red--a very small quantity of
+red in proportion to the yellow is sufficient for mahogany--and a piece
+of glue about the size of a walnut; the whole to be well stirred and
+boiled. Brush over while hot, and immediately rub off with soft shavings
+or a sponge. For the antique hues of old wainscot mix equal parts of
+burnt umber and brown ochre. For new oak, bird's-eye maple, birch,
+satin-wood, or any similar light yellowish woods, whiting or white-lead,
+tinted with orange chrome, or by yellow ochre and a little size. For
+walnut, brown umber, glue size, and water; or by burnt umber very
+moderately modified with yellow ochre. For rosewood, Venetian red tinted
+with lamp-black. For ebony, ivory-black; but for the common ebonised
+work lamp-black is generally used.
+
+When the colouring is dry, it should be rubbed down with a piece of worn
+fine glass-paper, and polished with beeswax rubbed on a very hard
+brush--a worn-out scrubbing-brush is as good as anything--or it can be
+well rubbed with Dutch rush. In polishing always rub the way of the
+grain. The cheap work seldom gets more than a coat of colour rubbed off
+with shavings.
+
+
+=Cheap but Valuable Stain for the Sap of Black Walnut.=--Take 1 gallon
+of strong vinegar, 1 lb. dry burnt umber, 1/2 lb. fine rose-pink, 1/2
+lb. dry burnt Vandyke brown. Put them into a jug and mix them well; let
+the mixture stand one day, and it will then be ready for use. Apply this
+stain to the sap with a piece of fine sponge; it will dry in half an
+hour. The whole piece is then ready for the filling process. When
+completed, the stained part cannot be detected even by those who have
+performed the work. This recipe is of value, as by it wood of poor
+quality and mostly of sap can be used with good effect.
+
+
+=Polish for Removing Stains, etc., from Furniture (American).=--Take 1/2
+pint alcohol, 1/4 oz. pulverised resin, 1/4 oz. gum shellac, 1/2 pint boiled
+linseed-oil. Shake the mixture well, and apply it with a sponge, brush,
+or cotton flannel, rubbing well after the application.
+
+
+=Walnut Stain to be used on Pine and White-wood.=--Take 1 gallon of very
+thin sized shellac; add 1 lb. of dry burnt umber, 1 lb. of dry burnt
+sienna, and 1/4 lb. of lamp-black. Put these articles into a jug, and
+shake frequently until they are mixed. Apply one coat with a brush. When
+the work is dry, sand-paper down with fine paper, and apply one coat of
+shellac or cheap varnish. It will then be a good imitation of solid
+walnut, and will be adapted for the back-boards of mirror-frames, for
+the backside and inside of case-work, and for similar work.
+
+
+=Rosewood Stain.=--Take 1 lb. of logwood chips, 1/2 lb. of red-sanders,
+1/2 gallon of water. Boil over a fire until the full strength is
+obtained. Apply the mixture, while hot, to the wood with a brush. Use
+one or two coats to obtain a strong red colour. Then take 1 gallon of
+spirits of turpentine and 2 lb. of asphaltum. Dissolve in an iron kettle
+on a stove, stirring constantly. Apply with a brush over the red stain,
+to imitate rosewood. To make a perfect black, add a little lamp-black.
+The addition of a small quantity of varnish with the turpentine will
+improve it. This stain applied to birchwood gives as good an imitation
+of rosewood as on black walnut, the shade on the birch being a little
+brighter.
+
+
+=Rosewood Stain for Cane Work, etc.=--Take 1 gallon alcohol, 1 lb.
+red-sanders, 1 lb. dragon's blood, 1 lb. extract logwood, 1/2 lb. gum
+shellac. Put the mixture into a jug, and steep well till it obtains its
+full strength. Then strain, and it will be ready for use. Apply with
+brush, giving one, two, or more coats, according to the depth of colour
+desired. Then give one or more coats of varnish. This stain is suitable
+for use on cane, willow, or reed work, and produces a good imitation of
+rosewood.
+
+
+=French Polish Reviver.=--This recipe will be found a valuable one. If
+the work is sweated and dirty, make it tolerably wet, and let it stand a
+few minutes; then rub off and polish with a soft rag. It is important
+that the ingredients should be mixed in a bottle in the order as given:
+Vinegar, 1 gill; methylated spirit, 1 gill; linseed-oil, 1/2 pint;
+butter of antimony (poison), 1 oz. Raw linseed-oil, moderately thinned
+with turpentine or spirits of wine, will also make a good reviver. Old
+furniture, or furniture that has been warehoused for a long time, should
+be washed with soda and warm water previous to applying the reviver.
+
+
+=Morocco Leather Reviver.=--The coverings of chairs or sofas in morocco,
+roan, or skiver can be much improved by this reviver. If old and greasy,
+wash with sour milk first. The reviver should be applied with a piece of
+wadding, and wiped one way only, as in glazing. The colour can be
+matched by adding red-sanders. Methylated spirit, 1/2 pint; gum benzoin,
+2 oz.; shellac, 1/2 oz. Mix, and shake up occasionally until dissolved.
+
+
+=Hair-cloth Reviver.=--Mix equal parts of marrow-oil (neats-foot),
+ox-gall. and ivory-black, to be well rubbed with a cloth. This
+composition forms a valuable renovator for old hair-cloth.
+
+
+=To Remove Grease Stains from Silks, Damasks, Cloth, etc.=--Pour over
+the stain a small quantity of benzoline spirit, and it will soon
+disappear without leaving the least mark behind. The most delicate
+colours can be so treated without fear of injury. For paint stains
+chloroform is very efficacious.
+
+
+=To Remove Ink Stains from White Marble.=--Make a little chloride of
+lime into a paste with water, and rub it into the stains, and let it
+remain a few hours; then wash off with soap and water.
+
+

+
+_MATERIALS USED._
+
+
+=Alkanet-root= (botanical name, _Anchusa tinctoria_).--This plant is a
+native of the Levant, but it is much cultivated in the south of France
+and in Germany. The root is the only part used by French polishers to
+obtain a rich quiet red; the colouring is chiefly contained in the bark
+or outer covering, and is easily obtained by soaking the root in spirits
+or linseed-oil. The plant itself is a small herbaceous perennial, and
+grows to about a foot in height, with lance-shaped leaves and purple
+flowers, and with a long woody root with a deep red bark.
+
+
+=Madder-root= (_Rubia tinctoria_).--This plant is indigenous to the
+Levant; but it is much cultivated in Southern Europe, and also in India.
+Its uses are for dyeing and staining; it can be procured in a powdered
+state, and imparts its red colour when soaked in water or spirits. This
+is a creeping plant with a slender stem; almost quadrangular, the
+leaves grow four in a bunch; flowers small, fruit yellow, berry double,
+one being abortive. The roots are dug up when the plant has attained the
+age of two or three years; they are of a long cylindrical shape, about
+the thickness of a quill, and of a red-brownish colour, and when
+powdered are a bright Turkish-red. Extracts of madder are mostly
+obtained by treating the root with boiling water, collecting the
+precipitates which separate on cooling, mixing them with gum or starch,
+and adding acetate of alumina or iron. This is in fact a mixture of
+colouring matter and a mordant.
+
+
+=Red-sanders= (_Pterocarpus santalinus_).--The tree from which this wood
+is obtained is a lofty one, and is to be found in many parts of India,
+especially about Madras. It yields a dye of a bright garnet-red colour,
+and is used by French polishers for dyeing polishes, varnishes,
+revivers, etc.
+
+
+=Logwood= (_Haematoxylon campeachianum_).--This is a moderate-sized tree
+with a very contorted trunk and branches, which are beset with sharp
+thorns, and blooms with a yellow flower. It is a native of Central
+America and the West Indies. This valuable dye-wood is imported in logs;
+the heart-wood is the most valuable, which is cut up into chips or
+ground to powder for the use of dyers by large powerful mills
+constructed especially for the purpose. Logwood, when boiled in water,
+easily imparts its red colour. If a few drops of acetic acid (vinegar)
+is added, a bright red is produced; and when a little alum is added for
+a mordant, it forms red ink. If an alkali, such as soda or potash, is
+used instead of an acid, the colour changes to a dark blue or purple,
+and with a little management every shade of these colours can be
+obtained. Logwood put into polish or varnish also imparts its red
+colour.
+
+
+=Fustic= (_Maclura tinctoria_).--This tree is a native of the West
+Indies, and imparts a yellow dye. Great quantities are used for dyeing
+linens, etc. The fustic is a large and handsome evergreen, and is
+imported in long sticks.
+
+
+=Turmeric= (_Curcuma longa_).--Turmeric is a stemless plant, with
+palmated tuberous roots and smooth lance-shaped leaves. It is imported
+from the East Indies and China. The root is the part which affords the
+yellow powder for dyeing. It is also a condiment, and is largely used in
+Indian curry-powder. Paper stained with turmeric is used by chemists as
+a test for alkalies, and it is also used in making Dutch, pink, and
+gold-coloured varnishes.
+
+
+=Indigo= (_Indigofera tinctoria_).--Indigo is a shrub which grows from
+two to three feet in height, and is cut down just as it begins to
+flower. It is cultivated in almost all the countries situated in the
+tropics. The dye substance is prepared from the stems and leaves, and is
+largely used in calico-printing.
+
+
+=Persian Berries= (_Rhamnus infectorius_).--These berries are the
+produce of a shrub of a species of buckthorn common in Persia, whence
+they derive their name; but large quantities are also imported into
+England from Turkey and the south of France. The berries are gathered in
+an unripe state, and furnish a yellow dye.
+
+
+=Nut-galls.=--These are found upon the young twigs of the Turkish dwarf
+oak (_Quercus infectoria_), and are produced by the puncture of an
+insect called Cynips. The supply is principally from Turkey and Aleppo.
+Nut-galls contain a large quantity of tannin and gallic acid, and are
+extensively used in dyeing.
+
+
+=Catechu.=--This is obtained from the East Indies, and is the extract of
+the _Acacia catechu_, a thorny tree. The wood is cut up into chips
+similar to logwood, and after boiling and evaporation the liquor
+assumes the consistency of tar; but when cold it hardens, and is formed
+into small squares. It is extensively used by tanners in place of oak
+bark.
+
+
+=Thus.=--Thus is the resin which exudes from the spruce-fir, and is used
+by some polishers in the making of polishes and varnishes.
+
+
+=Sandarach= is the produce of the _Thuya articulata_ of Barbary. It
+occurs in small pale yellow scales, slightly acid, and is soluble in
+alcohol; it is used in both polishes and varnishes.
+
+
+=Mastic= exudes from the mastic-tree (_Pistacia lentiscus_), and is
+principally obtained from Chios, in the Grecian Archipelago. It runs
+freely when an incision is made in the body of the tree, but not
+otherwise. It occurs in the form of nearly colourless and transparent
+tears of a faint smell, and is soluble in alcohol as well as oil of
+turpentine, forming a rapidly-drying but alterable varnish, which
+becomes brittle and dark-coloured by age.
+
+
+=Benzoin.=--This is the produce of the American tree _Laurus benzoin_,
+and also of the _Styrax benzoin_ of Sumatra, which is called "gum
+benjamin"; it is used in polishes and varnishes, and as a cosmetic, and
+is also burnt as incense in Catholic churches.
+
+
+=Copal= is one of the most valuable of gums, and is furnished by many
+countries in the districts of Africa explored by Mr. H. M. Stanley, the
+discoverer of Livingstone. Copal is found in a fossil state in very
+large quantities. The natives collect the gum by searching in the sandy
+soil, mostly in the hilly districts, the country being almost barren,
+with no large tree except the Adansonia, and occasionally a few thorny
+bushes.
+
+The gum is dug out of the earth by the copal gatherers at various
+depths, from two or three to ten or more feet, in a manner resembling
+gold-digging; and great excitement appears when a good amount is
+discovered. The gum is found in various shapes and sizes, resembling a
+hen's egg, a flat cake, a child's head, etc. There are three kinds,
+yellow, red, and whitish; and the first furnishes the best varnish and
+fetches the highest price from the dealers. Many of the natives assert
+that the copal still grows on different trees, and that it acquires its
+excellent qualities as a resin by dropping off and sinking several feet
+into the soil, whereby it is cleansed, and obtains, after a lapse of
+many years, its hardness, inflammability, and transparency.
+
+
+=Dragon's Blood= is the juice of certain tropical plants of a red
+colour, especially of the tree _Pterocarpus draco_. After the juice is
+extracted, it is reduced to a powder by evaporation. It is used for
+darkening mahogany, colouring varnishes or polishes, etc., and for
+staining marble. Chemists also use it in preparing tinctures and tooth
+powders.
+
+
+=Shellac=--or, more properly, _gum-lac_--is a resinous substance
+obtained from the Bihar-tree, and also from the _Ficus Indica_, or
+Banyan-tree. It exudes when the branches are pierced by an insect called
+the _Coccus ficus_. The twigs encrusted with the resin in its natural
+state is called Stick-lac. When the resin is broken off the twigs,
+powdered, and rubbed with water, a good deal of the red colouring matter
+is dissolved, and the granular resin left is called seed-lac; and when
+melted, strained, and spread into thin plates it is called shellac, and
+is prepared in various ways and known by the names of button, garnet,
+liver, orange, ruby, thread, etc., and is used for many purposes in the
+arts. Shellac forms the principal ingredient for polishes and spirit
+varnishes. Red sealing-wax is composed of shellac, Venice turpentine,
+and vermilion red; for the black sealing-wax ivory-black is used instead
+of the vermilion. Shellac is soluble in alcohol, and in many acids and
+alkalies. Lac-dye is the red colour from the stick-lac dissolved by
+water and evaporated to dryness. The dye, however, is principally from
+the shrivelled-up body of the insect of the Stick-lac.
+
+Shellac is produced in the largest quantity and the best quality in
+Bengal, Assam, and Burmah. The chief seat of manufacture is Calcutta,
+where the native manufacturers are accused of adulterating it with resin
+to a considerable extent. The best customers are Great Britain and the
+United States, though the demand in the Italian markets appears to be on
+the increase.
+
+
+=Amber= is a yellow, semi-transparent, fossil resin; hard but brittle,
+and easily cut with a knife; tasteless, and without smell, except when
+pounded or heated, and then it emits a fragrant odour. It has
+considerable lustre; becomes highly electric by friction; and will burn
+with a yellow flame. It is found in nodules of various sizes in alluvial
+soils, or on the seashore in many places, particularly on the shores of
+the Baltic. Amber is much employed for ornamental purposes, and is also
+used in the manufacture of amber-varnish. It will not dissolve in
+alcohol, but yields to the concentrated action of sulphuric acid, which
+will dissolve all resins except caramba wax.
+
+
+=Pumice-stone.=--This well-known light and spongy volcanic substance is
+extensively quarried in the small islands that lie off the coast of
+Sicily. Its porosity and smooth-cutting properties render it of great
+value to painters and polishers for levelling down first coatings.
+Ground pumice-stone is the best for cutting down bodies of polish or
+varnish that are more advanced towards completion. The best way to get a
+surface to a piece of lump pumice-stone is to rub it down on a flat York
+stone, or, better still, an old tile that has been well baked.
+Pumice-stone should not be allowed to stand in water; it causes the
+grain to contract and to harden, thereby deteriorating its cutting
+properties.
+
+
+=Linseed-oil.=--This valuable oil is obtained by pressure from the seed
+of the flax plant (_Linum usitatissimum_). Linseed contains on an
+average about 33 per cent. of oil, though the amount varies materially,
+the percentage obtained fluctuating considerably, not being alike on any
+two successive days. This is partly due to the varying richness of the
+seed, and partly to the manner in which it is manipulated in extracting
+the oil, it being a very easy matter to lose a considerable percentage
+of the oil by a lack of skill in any of the processes, though they all
+seem so simple.
+
+The first thing done with the seed from which the oil is to be extracted
+is to pass it through a screen, to cleanse it from foreign substances.
+The seed is received in bags containing from three to four bushels, and
+pockets containing one-sixth of that amount. Having been screened it is
+passed through a mill, whose large iron-rollers, three in number, grind
+it to a coarse meal. Thence it is carried to what are known as the
+"mullers," which are two large stones, about eight feet in diameter and
+eighteen inches thick, weighing six tons each, standing on their edges,
+and rolling around on a stone bed. About five bushels of the meal are
+placed in the mullers, and about eight quarts of hot water are added.
+The meal is afterwards carried by machinery to the heaters, iron pans
+holding about a bushel each. These are heated to an even temperature by
+steam, and are partly filled with the meal, which for seven minutes is
+submitted to the heat, being carefully stirred in order that all parts
+may become evenly heated. At the end of that time the meal is placed in
+bags, which in turn are placed in hydraulic presses, iron plates being
+placed between the bags. Pressure is applied for about eight minutes,
+until, as is supposed, all the oil is pressed out, leaving a hard cake,
+known to the trade as oil-cake, or linseed-cake.
+
+The product of these various processes is known as "raw" oil, a
+considerable portion of which is sold without further labour being
+expended upon it. There is, however, a demand for "boiled" oil, for
+certain purposes where greater drying properties are needed. To supply
+this want oil is placed in large kettles, holding from five hundred to
+one thousand gallons, where it is heated to a temperature of about 500
+degrees, being stirred continually. This process, when large kettles are
+used, requires nearly the entire day. While the boiling process is going
+on, oxide of manganese is added, which helps to give the boiled oil
+better drying properties. A considerable portion of the oil is bleached,
+for the use of manufacturers of white paints.
+
+
+=Venice Turpentine.=--This is obtained from the larch, and is said to be
+contained in peculiar sacs in the upper part of the stem, and to be
+obtained by puncturing them. It is a ropy liquid, colourless or brownish
+green, having a somewhat unpleasant odour and bitter taste.
+
+
+=Oil of Turpentine= is the most plentiful and useful of oils. It is
+obtained in America from a species of pine very plentiful in the
+Carolinas, Georgia, and Alabama, known as the long-leaved pine (_pinus
+Australis_), and found only where the original forest has not been

+
+=Methylated Spirits.=--The methylated spirit of commerce usually
+consists of the ordinary mixed grain, or "plain" spirit, as produced by
+the large distillers in London and elsewhere, with which are blended,
+by simply mixing in various proportions, one part vegetable naphtha and
+three parts spirits of wine. The mixing takes place in presence of a
+revenue officer, and the spirits so "methylated" are allowed to be used
+duty free. The revenue authorities consider the admixture of naphtha,
+having so pungent and disagreeable a smell, a sufficient security
+against its sale and consumption as a beverage. No process has yet been
+discovered of getting rid of this odour. It is illegal for druggists to
+use it in the preparation of medicinal tinctures, unless they are for
+external use.

+THE FULL PROJECT GUTENBERG LICENSE
+PLEASE READ THIS BEFORE YOU DISTRIBUTE OR USE THIS WORK
+
+To protect the Project Gutenberg-tm mission of promoting the free
+distribution of electronic works, by using or distributing this work
+(or any other work associated in any way with the phrase "Project
+Gutenberg"), you agree to comply with all the terms of the Full Project
+Gutenberg-tm License (available with this file or online at
+http://gutenberg.org/license).
+
+
+Section 1. General Terms of Use and Redistributing Project Gutenberg-tm
+electronic works
+
+1.A. By reading or using any part of this Project Gutenberg-tm
+electronic work, you indicate that you have read, understand, agree to
+and accept all the terms of this license and intellectual property
+(trademark/copyright) agreement. If you do not agree to abide by all
+the terms of this agreement, you must cease using and return or destroy
+all copies of Project Gutenberg-tm electronic works in your possession.
+If you paid a fee for obtaining a copy of or access to a Project
+Gutenberg-tm electronic work and you do not agree to be bound by the
+terms of this agreement, you may obtain a refund from the person or
+entity to whom you paid the fee as set forth in paragraph 1.E.8.
+
+1.B. "Project Gutenberg" is a registered trademark. It may only be
+used on or associated in any way with an electronic work by people who
+agree to be bound by the terms of this agreement. There are a few
+things that you can do with most Project Gutenberg-tm electronic works
+even without complying with the full terms of this agreement. See
+paragraph 1.C below. There are a lot of things you can do with Project
+Gutenberg-tm electronic works if you follow the terms of this agreement
+and help preserve free future access to Project Gutenberg-tm electronic
+works. See paragraph 1.E below.
+
+1.C. The Project Gutenberg Literary Archive Foundation ("the Foundation"
+or PGLAF), owns a compilation copyright in the collection of Project
+Gutenberg-tm electronic works. Nearly all the individual works in the
+collection are in the public domain in the United States. If an
+individual work is in the public domain in the United States and you are
+located in the United States, we do not claim a right to prevent you from
+copying, distributing, performing, displaying or creating derivative
+works based on the work as long as all references to Project Gutenberg
+are removed. Of course, we hope that you will support the Project
+Gutenberg-tm mission of promoting free access to electronic works by
+freely sharing Project Gutenberg-tm works in compliance with the terms of
+this agreement for keeping the Project Gutenberg-tm name associated with
+the work. You can easily comply with the terms of this agreement by
+keeping this work in the same format with its attached full Project
+Gutenberg-tm License when you share it without charge with others.
+
+1.D. The copyright laws of the place where you are located also govern
+what you can do with this work. Copyright laws in most countries are in
+a constant state of change. If you are outside the United States, check
+the laws of your country in addition to the terms of this agreement
+before downloading, copying, displaying, performing, distributing or
+creating derivative works based on this work or any other Project
+Gutenberg-tm work. The Foundation makes no representations concerning
+the copyright status of any work in any country outside the United
+States.
+
+1.E. Unless you have removed all references to Project Gutenberg:
+
+1.E.1. The following sentence, with active links to, or other immediate
+access to, the full Project Gutenberg-tm License must appear prominently
+whenever any copy of a Project Gutenberg-tm work (any work on which the
+phrase "Project Gutenberg" appears, or with which the phrase "Project
+Gutenberg" is associated) is accessed, displayed, performed, viewed,
+copied or distributed:
+
+This eBook is for the use of anyone anywhere at no cost and with
+almost no restrictions whatsoever. You may copy it, give it away or
+re-use it under the terms of the Project Gutenberg License included
+with this eBook or online at www.gutenberg.org
+
+1.E.2. If an individual Project Gutenberg-tm electronic work is derived
+from the public domain (does not contain a notice indicating that it is
+posted with permission of the copyright holder), the work can be copied
+and distributed to anyone in the United States without paying any fees
+or charges. If you are redistributing or providing access to a work
+with the phrase "Project Gutenberg" associated with or appearing on the
+work, you must comply either with the requirements of paragraphs 1.E.1
+through 1.E.7 or obtain permission for the use of the work and the
+Project Gutenberg-tm trademark as set forth in paragraphs 1.E.8 or
+1.E.9.
+
+1.E.3. If an individual Project Gutenberg-tm electronic work is posted
+with the permission of the copyright holder, your use and distribution
+must comply with both paragraphs 1.E.1 through 1.E.7 and any additional
+terms imposed by the copyright holder. Additional terms will be linked
+to the Project Gutenberg-tm License for all works posted with the
+permission of the copyright holder found at the beginning of this work.
+
+1.E.4. Do not unlink or detach or remove the full Project Gutenberg-tm
+License terms from this work, or any files containing a part of this
+work or any other work associated with Project Gutenberg-tm.
+
+1.E.5. Do not copy, display, perform, distribute or redistribute this
+electronic work, or any part of this electronic work, without
+prominently displaying the sentence set forth in paragraph 1.E.1 with
+active links or immediate access to the full terms of the Project
+Gutenberg-tm License.
+
+1.E.6. You may convert to and distribute this work in any binary,
+compressed, marked up, nonproprietary or proprietary form, including any
+word processing or hypertext form. However, if you provide access to or
+distribute copies of a Project Gutenberg-tm work in a format other than
+"Plain Vanilla ASCII" or other format used in the official version
+posted on the official Project Gutenberg-tm web site (www.gutenberg.org),
+you must, at no additional cost, fee or expense to the user, provide a
+copy, a means of exporting a copy, or a means of obtaining a copy upon
+request, of the work in its original "Plain Vanilla ASCII" or other
+form. Any alternate format must include the full Project Gutenberg-tm
+License as specified in paragraph 1.E.1.
+
+1.E.7. Do not charge a fee for access to, viewing, displaying,
+performing, copying or distributing any Project Gutenberg-tm works
+unless you comply with paragraph 1.E.8 or 1.E.9.
+
+1.E.8. You may charge a reasonable fee for copies of or providing
+access to or distributing Project Gutenberg-tm electronic works provided
+that
+
+- You pay a royalty fee of 20% of the gross profits you derive from
+ the use of Project Gutenberg-tm works calculated using the method
+ you already use to calculate your applicable taxes. The fee is
+ owed to the owner of the Project Gutenberg-tm trademark, but he
+ has agreed to donate royalties under this paragraph to the
+ Project Gutenberg Literary Archive Foundation. Royalty payments
+ must be paid within 60 days following each date on which you
+ prepare (or are legally required to prepare) your periodic tax
+ returns. Royalty payments should be clearly marked as such and
+ sent to the Project Gutenberg Literary Archive Foundation at the
+ address specified in Section 4, "Information about donations to
+ the Project Gutenberg Literary Archive Foundation."
+
+- You provide a full refund of any money paid by a user who notifies
+ you in writing (or by e-mail) within 30 days of receipt that s/he
+ does not agree to the terms of the full Project Gutenberg-tm
+ License. You must require such a user to return or
+ destroy all copies of the works possessed in a physical medium
+ and discontinue all use of and all access to other copies of
+ Project Gutenberg-tm works.
+
+- You provide, in accordance with paragraph 1.F.3, a full refund of any
+ money paid for a work or a replacement copy, if a defect in the
+ electronic work is discovered and reported to you within 90 days
+ of receipt of the work.
+
+- You comply with all other terms of this agreement for free
+ distribution of Project Gutenberg-tm works.
+
+1.E.9. If you wish to charge a fee or distribute a Project Gutenberg-tm
+electronic work or group of works on different terms than are set
+forth in this agreement, you must obtain permission in writing from
+both the Project Gutenberg Literary Archive Foundation and Michael
+Hart, the owner of the Project Gutenberg-tm trademark. Contact the
+Foundation as set forth in Section 3 below.
+
+1.F.
+
+1.F.1. Project Gutenberg volunteers and employees expend considerable
+effort to identify, do copyright research on, transcribe and proofread
+public domain works in creating the Project Gutenberg-tm
+collection. Despite these efforts, Project Gutenberg-tm electronic
+works, and the medium on which they may be stored, may contain
+"Defects," such as, but not limited to, incomplete, inaccurate or
+corrupt data, transcription errors, a copyright or other intellectual
+property infringement, a defective or damaged disk or other medium, a
+computer virus, or computer codes that damage or cannot be read by
+your equipment.
+
+1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the "Right
+of Replacement or Refund" described in paragraph 1.F.3, the Project
+Gutenberg Literary Archive Foundation, the owner of the Project
+Gutenberg-tm trademark, and any other party distributing a Project
+Gutenberg-tm electronic work under this agreement, disclaim all
+liability to you for damages, costs and expenses, including legal
+fees. YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT
+LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE
+PROVIDED IN PARAGRAPH F3. YOU AGREE THAT THE FOUNDATION, THE
+TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE
+LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR
+INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH
+DAMAGE.
+
+1.F.3. LIMITED RIGHT OF REPLACEMENT OR REFUND - If you discover a
+defect in this electronic work within 90 days of receiving it, you can
+receive a refund of the money (if any) you paid for it by sending a
+written explanation to the person you received the work from. If you
+received the work on a physical medium, you must return the medium with
+your written explanation. The person or entity that provided you with
+the defective work may elect to provide a replacement copy in lieu of a
+refund. If you received the work electronically, the person or entity
+providing it to you may choose to give you a second opportunity to
+receive the work electronically in lieu of a refund. If the second copy
+is also defective, you may demand a refund in writing without further
+opportunities to fix the problem.
+
+1.F.4. Except for the limited right of replacement or refund set forth
+in paragraph 1.F.3, this work is provided to you 'AS-IS', WITH NO OTHER
+WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO
+WARRANTIES OF MERCHANTIBILITY OR FITNESS FOR ANY PURPOSE.
+
+1.F.5. Some states do not allow disclaimers of certain implied
+warranties or the exclusion or limitation of certain types of damages.
+If any disclaimer or limitation set forth in this agreement violates the
+law of the state applicable to this agreement, the agreement shall be
+interpreted to make the maximum disclaimer or limitation permitted by
+the applicable state law. The invalidity or unenforceability of any
+provision of this agreement shall not void the remaining provisions.
+
+1.F.6. INDEMNITY - You agree to indemnify and hold the Foundation, the
+trademark owner, any agent or employee of the Foundation, anyone
+providing copies of Project Gutenberg-tm electronic works in accordance
+with this agreement, and any volunteers associated with the production,
+promotion and distribution of Project Gutenberg-tm electronic works,
+harmless from all liability, costs and expenses, including legal fees,
+that arise directly or indirectly from any of the following which you do
+or cause to occur: (a) distribution of this or any Project Gutenberg-tm
+work, (b) alteration, modification, or additions or deletions to any
+Project Gutenberg-tm work, and (c) any Defect you cause.
+
+
+Section 2. Information about the Mission of Project Gutenberg-tm
+
+Project Gutenberg-tm is synonymous with the free distribution of
+electronic works in formats readable by the widest variety of computers
+including obsolete, old, middle-aged and new computers. It exists
+because of the efforts of hundreds of volunteers and donations from
+people in all walks of life.
+
+Volunteers and financial support to provide volunteers with the
+assistance they need, is critical to reaching Project Gutenberg-tm's
+goals and ensuring that the Project Gutenberg-tm collection will
+remain freely available for generations to come. In 2001, the Project
+Gutenberg Literary Archive Foundation was created to provide a secure
+and permanent future for Project Gutenberg-tm and future generations.
+To learn more about the Project Gutenberg Literary Archive Foundation
+and how your efforts and donations can help, see Sections 3 and 4
+and the Foundation web page at http://www.pglaf.org.
+
+
+Section 3. Information about the Project Gutenberg Literary Archive

+501(c)(3) educational corporation organized under the laws of the
+state of Mississippi and granted tax exempt status by the Internal
+Revenue Service. The Foundation's EIN or federal tax identification
+number is 64-6221541. Its 501(c)(3) letter is posted at
+http://pglaf.org/fundraising. Contributions to the Project Gutenberg
+Literary Archive Foundation are tax deductible to the full extent
+permitted by U.S. federal laws and your state's laws.

+ Chief Executive and Director
+ gbnewby@pglaf.org
+
+Section 4. Information about Donations to the Project Gutenberg
+Literary Archive Foundation
+
+Project Gutenberg-tm depends upon and cannot survive without wide
+spread public support and donations to carry out its mission of
+increasing the number of public domain and licensed works that can be
+freely distributed in machine readable form accessible by the widest
+array of equipment including outdated equipment. Many small donations
+($1 to $5,000) are particularly important to maintaining tax exempt
+status with the IRS.
+
+The Foundation is committed to complying with the laws regulating
+charities and charitable donations in all 50 states of the United
+States. Compliance requirements are not uniform and it takes a
+considerable effort, much paperwork and many fees to meet and keep up
+with these requirements. We do not solicit donations in locations
+where we have not received written confirmation of compliance. To
+SEND DONATIONS or determine the status of compliance for any
+particular state visit http://pglaf.org
+
+While we cannot and do not solicit contributions from states where we
+have not met the solicitation requirements, we know of no prohibition
+against accepting unsolicited donations from donors in such states who
+approach us with offers to donate.
+
+International donations are gratefully accepted, but we cannot make
+any statements concerning tax treatment of donations received from
+outside the United States. U.S. laws alone swamp our small staff.
+
+Please check the Project Gutenberg Web pages for current donation
+methods and addresses. Donations are accepted in a number of other
+ways including checks, online payments and credit card
+donations. To donate, please visit: http://pglaf.org/donate

+Section 5. General Information About Project Gutenberg-tm electronic
+works.
+
+Professor Michael S. Hart is the originator of the Project Gutenberg-tm
+concept of a library of electronic works that could be freely shared
+with anyone. For thirty years, he produced and distributed Project
+Gutenberg-tm eBooks with only a loose network of volunteer support.
+
+Project Gutenberg-tm eBooks are often created from several printed
+editions, all of which are confirmed as Public Domain in the U.S.
+unless a copyright notice is included. Thus, we do not necessarily
+keep eBooks in compliance with any particular paper edition.
+
+Most people start at our Web site which has the main PG search facility:
+
+ http://www.gutenberg.org
+
+This Web site includes information about Project Gutenberg-tm,
+including how to make donations to the Project Gutenberg Literary
+Archive Foundation, how to help produce our new eBooks, and how to
+subscribe to our email newsletter to hear about new eBooks.
