In all these cases it will be seen that we have eight parts of blue, five of red, and three of yellow, only the mode of combination varies. This variation may occur to any extent, provided the totals of each be always the equivalent proportions.
These remarks will apply equally to hues of colour, shades, and tints, and to shades and tints of hues.
Care, and a little practice, will enable the learner to arrange colours into a number of degrees of depth, or shades, as they are generally called. (We do not here use the term as signifying pure colours darkened with black.) Ten shades of each colour differing obviously in degree of depth can readily be arranged by the experienced, the ten shades being equidistant from each other as regards depth—that is, shade 3 will be as much darker than shade 2 as shade 2 is darker than shade 1, and so on throughout the whole. Purple is a colour intermediate between blue and red. Imagine ten hues between the purple and the red, and ten more between the purple and the blue: thus we should have purple, then a slightly red purple, then a rather redder purple, then a purple still redder, and so on till we get purple-reds, andfinally the pure red; and the same variations of hue at the blue side also. Imagine, further, the green having ten hues extending towards the blue, and ten more stretching towards the yellow; and the orange having ten hues towards the red, and ten towards the yellow—in all cases I count the colour from which we start as one of the ten, thus:—
—and we shall have 54 colours and hues of colour. Of each of these 54 colours and hues imagine 10 degrees of depth, and we get 540 colours, hues, tints, and shades, all differing from one another to an obvious degree.
Mark this fact, that any colour, tint, hue, or shade of such a diagram has its complement in one other of the colours, tints, hues, or shades of the diagram, and that only two of this series of 540 are complementary to each other; thus, if you fix on any one colour of the 540, there is but one colour in the whole that is complementary to it, and it is complementary to but this one other colour.
The student will do well to try and make a colour-diagram of this kind, of a simple character, say such as the following, only using pigments for my numbers; but in doing so he must exercise the utmost care, in order that he secure some degree of accuracy of tint or shade, and if he can call to his aid an experienced colourist it will be of great assistance to him.
This table is highly valuable, as it gives ninety harmonies, if carefully prepared in colour; and the preparation of such a table is the very best practice that a student can possibly have.
Let us for a moment consider this table, and suppose that we want to find the complement to some particular colour, as the third shade of red. We find the complement of this in the third shade of green opposite. If we want the complement of the second shade of orange-yellow, we find it in the second shade of blue-purple opposite, and so on. Thus we have a means of at once judging of the harmony of colours.
It must ever be borne in mind that pigments mixed in the proportions given will not yield results such as would occur when the coloured rays of light are combined; thus three parts, either by weight or measure, of chrome yellow when combined with eight parts of ultramarine would not form a colour representing the secondary green, nor would the result be more satisfactory were other pigments combined in the proportions given. What we have said in respect to the proportions in which colours combine to form new colours applies only to the coloured rays of light.
It must now be noticed that while colours harmonise in the proportions stated, the areas occupied by the different colours may vary if there be a corresponding alteration in intensity. Thus eight of blue and eight of orange form a perfect harmony when both colours are of prismatic intensity; but we shall still have a perfect harmony if the orange is diluted to one-half its strength with white, and thus formed into a tint, provided there be sixteen parts of this orange of half strength to the eight parts of blue of full strength.
The orange might be further diluted to one-third of its full power, but then twenty-four parts would be necessary to a perfect harmony with eight parts of prismatic blue; or to one-fourth of its strength, when thirty-two parts would be necessary to the harmony.
It is not desirable that I occupy space with diagrams of these quantities, but the industrious student will prepare them for himself, and will strive to realise a true half-tint, quarter-tint, etc., which is not a very easy thing to do. By practice, however, it will readily be accomplished, and anything achieved is a new power gained.
What I have said respecting the harmony of blue with tints of orange will apply in all similar cases. Thus red will harmonise with tints of green, provided the area of the tint be increased as the intensity is decreased; and so will yellow harmonise with tints of purple under similar conditions.
But we may reverse the conditions, and lower the primary to a tint retaining the secondary in its intensity. Thus blue, if reduced to a half-tint, will harmonise with orange of prismatic intensity in the proportion of sixteen of blue to eight oforange; or, if reduced to a quarter-tint, in the proportion o£ thirty-two of blue to eight of orange. Red, if reduced to a half-tint, will harmonise in the proportion of ten red to eleven of green; and yellow as a half-tint in the proportion of six yellow to thirteen of purple.
The same remarks might be made respecting the harmony of shades of colour with colours of prismatic intensity. Thus, if orange is diluted to a shade of half intensity with black, it will harmonise with pure blue in the proportion of sixteen of orange to eight of blue, and so on, just as in the case of tints; and this principle applies to the harmony of all hues of colour also.
To go one step further: we scarcely ever deal with pure colours or their shades or tints, or even come as near them as we can. With great intensity of colour we seem to require an ethereal character, such as we have in those of light; but our pigments are coarse and earthy—they are too real-looking, and are not ethereal—they may be said to be corporeal rather than spiritual in character. For this reason we have to avoid the use of our purest pigments in such quantities as render their poverty of nature manifest, and to use for large surfaces such tints as, through their subtlety of composition, interest and please. A tint the composition of which is not apparent is always preferable to one of more obvious formation. Thus we are led to use tints which are subtly formed, and such as please by their newness and bewilder by the intricacy of formation.
To do what I here mean it is not necessary that many pigments be mixed together in order to the formation of a tint. The effect of which I speak can frequently be got by two well-chosen pigments. Thus a fine series of low-toned shades can be produced by mixing together middle-chrome and brown-lake in various proportions, and in all of the shades thus formed the three primary colours will be represented, but in some yellow will predominate, and in others red; while in many it will not be easy to discover to what proportionate extent the three primary colours are present.
Let us suppose that we make a tint by adding white to cobalt blue. This blue contains a small amount of yellow, and is a slightly green blue. But to this tint we add a small amount of raw umber with the view of imparting a greyness[15]or atmospheric character. Raw umber is a neutral colour, leaning slightly to yellow—that is, it consists of red, blue, and yellow, with a slight excess of the latter. In order that an orange harmonise with this grey-blue of a slightly yellow tone, the orange must be slightly inclined to red, so as to form the complement of the little green formed by the yellow in the blue. It may harmonise with the grey-blue as a pure tint if the area of the diluted and neutralised primary issufficiently extended, or may itself be likewise reduced to a tint of the same depth, when both tints would have the same area.
I might go on multiplying cases of this character to almost any extent, but these I leave the student to work out for himself, and pass to notice that while it is desirable to use subtle tints (often called "broken tints") it is rarely expedient to make up the full harmony by a large area of a tertiary tone and a single positive colour. Thus, we might have a shade or a tint of citrine spreading over a large surface as a ground on which we wished to place a figure. This figure would harmonise in pure purple were it of a certain size, and yet if thus coloured it would give a somewhat common-place effect when finished, for the harmony would be too simple and obvious. It would be much better to have the nineteen parts of citrine reduced, say, to half intensity, when the area would be increased to thirty-eight, with the figure of eight parts of blue and five of red, than of thirteen parts of purple.
But it would be better still if there were the thirty-eight parts of reduced citrine, three parts of pure yellow, thirteen of purple, five of red, and eight of blue, together with white, black, or gold, or all three (these may be added without altering the conditions, as all act as neutrals), for here the harmony is of a more subtle character.
If we count up the equivalents of the colours employed in this scheme of harmony, we shall see that we have, in the citrine—
Yellow6 (two equivalents).Blue8 (one equivalent).Red5 (one equivalent).In the purple—Blue8 (one equivalent).Red5 (one equivalent).Of the pure colours—Yellow3 (one equivalent).Red5 (one equivalent).Blue8 (one equivalent).
Yellow6 (two equivalents).Blue8 (one equivalent).Red5 (one equivalent).
In the purple—
Blue8 (one equivalent).Red5 (one equivalent).
Of the pure colours—
Yellow3 (one equivalent).Red5 (one equivalent).Blue8 (one equivalent).
Thus we have three equivalents of each primary, which give a perfect harmony.
I must not say more respecting the laws of harmony, for in the space of a small work it is impossible to do so, but proceed to notice certain effects or properties of colours, which I have as yet only alluded to, or have passed altogether unnoticed.
I have said that black, white, and gold are neutral as regards colour. This is the case, although many would suppose that gold was a yellow. Gold will act as a yellow, but it is generally employed as a neutral in decorative work, andit is more of a neutral than a yellow, for both red and blue exist largely in it. The pictorial artist frames his picture with gold because it, being a neutral, does not interfere with the tints of his work. It has the further advantage of being rich and costly in appearance, and thus of giving an impression of worth where it exists.
Black, white, and gold, being neutral, may be advantageously employed to separate colours where separation is necessary or desirable.
Yellow and purple harmonise, but yellow is a light colour and purple is dark. These colours not only harmonise, but also contrast as to depth, the one being light and the other dark. The limit of each colour, wherever these are used in juxtaposition, is therefore obvious.
It is not so with red and green, for these harmonise when of the same depth. This being the case, and red being a glowing colour, if a red object is placed on a green ground, or a green object on a red ground, the "figure" and ground will appear to "swim" together, and will produce a dazzling effect. Colour must assist form, and not confuse it. It will do this in the instance just named if the figure is outlined with black, white, or gold, and there will be no loss of harmony. But experience has shown that this effect can also be averted by outlining the figure with a lighter tint of its own colour. Thus, if the figure is red and the ground green, an outline of lighter red (pink) may be employed.(See Proposition 26, page 34.)
A blue figure on a red ground (as ultramarine on carmine), or a red figure on a blue ground, will also produce this swimming and unsatisfactory effect, but this is again obviated by an outline of black, white, or gold.
Employing the outline thus must not be regarded as a means of merely rendering what was actually unpleasant endurable, for it does much more—it affords one of the richest means of effect. A carmine ground well covered with bold green ornament having a gold outline is, if well managed, truly gorgeous; and were the figure blue on the red ground, the lavish use of gold would render the employment of yellow unnecessary as the yellow formed in the eye and cast upon the gold would satisfy all requirements.
It is a curious fact that the eye will create any colour of which there is a deficiency. This it will do, but the colour so created is of little use to the composition unless white or gold is present; if, however, there be white or gold in the composition, the colour which is absent, or is insufficiently represented, will be formed in the eye and cast upon these neutrals, and the white or the gold, as the case may be, will assume the tint of the deficient or absent colour.(See Propositions 8and 9, page 32.)
While this occurs (and sometimes it occurs to a marked degree, as can be shown by experiment), it must not be supposed that a composition in which any element iswanting is as perfect as one which reveals no want. It is far otherwise; only Nature here comes to our assistance, and is content to help herself rather than endure our short-comings; but in the one case we give Nature the labour of completing the harmony; while in the other, all being prepared, we receive a sense of satisfaction and repose.
In Proposition 8 we showed that when blue and black are juxtaposed, the black becomes "rusty," or assumes an orange tint; and in Proposition 9 we gave the cause of this effect. Let a blue spot be placed on a black silk necktie, and however black the silk, it will yet appear rusty. This is a fact; but we sometimes desire to employ blue on black, and wish the black to look black, and not an orange-black. How can we do this? Obviously by substituting for the black a very dark blue, as indigo. The bright blue spot induces orange (the complement of blue) in the eye. This orange, when cast upon black, causes the latter to look "rusty;" but if we place in the black an amount of blue sufficient to neutralise the orange cast upon it, the effect will be that of a jet-black.
We have now considered those qualities of colour, and those laws of contrast and harmony, which may be said to be of the grosser sort; but we have scarcely touched on those considerations which pertain to special refinement or tenderness of effect. But let me close the part of my subject of which I have treated, by repeating a statement already made—a statement, let me say, which first led me to perceive really harmony of colour—thatthose colours, and those particular hues of colour, which improve each other to the utmost, are those which perfectly harmonise. (Consider this statement in connection withPropositions 8, 9, 10, and 14, pages 32 and 33.)
We come now to consider delicacies and refinements in colour effects, which, although dependent upon the skilful exercise of the laws enunciated, are yet of a character, the power to produce which only results from the consideration of the works of the masters of great art-nations; but of these effects I can say little beyond pointing out what should be studied.
This principle however I cannot pass without notice—namely, that the finest colour effects are those of a rich, mingled, bloomy character.
Imagine a luxuriant garden, the beds in which are filled with a thousand flowers, having all the colours of the rainbow, and imagine these arranged as closely together as will permit of their growth. When viewed from a distance the effect is soft and rich, and full and varied, and is all that is pleasant. This is Nature's colouring. It is our work humbly to strive at producing like beauty with her.
This leads me to notice that primary colours (and secondary colours, also, when of great intensity) should be used chiefly in small masses, together with gold, white, or black.
Visit the Indian Museum at Whitehall,[16]and consider the beautiful Indian shawls and scarves and table-covers; or, if unable to do so, look in the windows of our large drapers in the chief towns, and see the true Indian fabrics,[17]and observe the manner in which small portions of intense reds, blues, yellows, greens, and a score of tertiary tints, are combined with white and black and gold to produce a very miracle of bloom. I know of nothing in the way of colour combination so rich, so beautiful, so gorgeous, and yet so soft, as some of these Indian shawls.
It is curious that we never find a purely Indian work otherwise than in good taste as regards colour harmony. Indian works, in this respect—whether carpets, or shawls, or dress materials, or lacquered boxes, or enamelled weapons—are almost perfect—perfect in harmony, perfect in richness, perfect in the softness of their general effect. How strangely these works contrast with ours, where an harmonious work in colours is scarcely ever seen.
By the co-mingling (not co-mixing) of colours in the manner just described, a rich and bloomy effect can be got, having the general tone of a tertiary colour of any desired hue. Thus, if a wall be covered with little ornamental flowerets, by colouring all alike, and letting each contain two parts of yellow and one part of blue and one of red, as separate and pure colours, the distant hue will be that of citrine: the same effect will result if the flowers are coloured variously, while the same proportions of the primaries are preserved throughout. I can conceive of no decorative effects more subtle, rich, and lovely than those of which I now speak.
Imagine three rooms, all connected by open archways, and all decorated with a thousand flower-like ornaments, and these so coloured, in this mingled manner, that in one room blue predominates, in another red, and in another yellow; we should then have a beautiful tertiary bloom in each—a subtle mingling of colour, an exquisite delicacy and refinement of treatment, a fulness such as always results from a rich mingling of hues, and an amount of detail which would interest when closely inspected; besides which, we should have the harmony of the general effect of the three rooms, the one appearing as olive, another as citrine, and the other as russet.
This mode of decoration has this advantage, that it not only gives richness and beauty, but it also gives purity. If pigments are mixed together they are thereby reduced in intensity, as we have already seen; but if placed side by side, when viewed from a distance the eye will mix them, but they will suffer no diminution of brilliancy.
With the view of cultivating the eye, Eastern works cannot be too carefully studied. The Indian Museum should be the home of all who can avail themselves of the opportunity of study which it affords; and the small Indian department of theSouth Kensington Museum should not be neglected, small though it is.[18]Chinese works must also be considered, for they likewise supply most valuable examples of colour harmony; and although they do not present such a perfect colour bloom as do the works of India, yet they are never inharmonious, and give clearness and sharpness, together with great brilliancy, in a manner not attempted by the Indians.
The best works of Chinese embroidery are rarely seen in this country; but these are unsurpassed by the productions of any other people. For richness, splendour, and purity of colour, together with a delicious coolness, I know of nothing to equal them.
The works of the Japanese are not to be overlooked, for in certain branches of art they are inimitable, and as colourists they are almost perfect. On the commonest of their lacquer trays we generally have a bit of good colouring, and their coloured pictures are sometimes marvels of harmony.
As to the styles of colouring adopted by the nations referred to, I should say that the Indians produce rich, mingled, bloomy,warmeffects—that is, effects in which red and yellow prevail; that the Chinese achieve clearness, repose, andcoolness—a form of colouring in which blue and white prevail; and that the Japanese effects arewarm, simple, and quiet.
Besides studying the works of India, China, and Japan, study those also of Turkey and Morocco, and even those of Algeria, for here the colouring is much better than with us, although not so good as in the countries first named. No aid to progress must be neglected, and no help must be despised.[19]
With the view of refining the judgment further in respect to colour, get a good colour-top,[20]and study its beautiful effects. See also the "gas tubes" illuminatedby electricity, as sold by opticians, and let the prism yield you daily instruction. Soap-bubbles may also be blown, and the beautiful colours seen in them carefully noted. These and any other available means of cultivating the eye should constantly be resorted to, as by such means only can we become great colourists.
As to works on colour, we have the writings of Field, to whom we are indebted for valuable discoveries; of Hay, the decorator, and friend of the late David Roberts, but some of his ideas are wild and Utopian; of Chevreul, whose work will be most useful to the student; and the small catechism of colour by Mr. Redgrave, of the South Kensington Museum, which is excellent. The student will also do well to carefully study the excellent manual of "Colour" by Professor Church, of Cirencester College.

Having considered those principles which are of primary importance to the ornamentist, we may commence our notice of the various manufactures, and try to discover what particular form of art should be applied to each, and the special manner in which decorative principles should be considered as applicable to various materials and modes of working.
We shall first consider furniture, or cabinet-work, because articles of furniture occupy a place of greater importance in a room than carpets, wall-papers, or, perhaps, any other decorative works; and, also, because we shall learn from a consideration of furniture those structural principles which will be of value to us in considering the manner in which all art-objects should be formed if they have solid, and not simply superficial, dimensions.
In the present chapter, I shall strive to impress the fact that design and ornamentation may be essentially different things, and that in considering the formation of works of furniture these should be regarded as separate and distinct. "Design," says Redgrave, "has reference to the construction of any work both for use and beauty, and therefore includes its ornamentation also. Ornament is merely the decoration of a thing constructed."
The construction of furniture will form the chief theme of this chapter, for unless such works are properly constructed they cannot possibly be useful, and if not useful they would fail to answer the end for which they were contrived.
But before commencing a consideration of the principles involved in the construction of works of furniture, let me summarise what is required in such works if they are to assume the character of art-objects.
1. The general form, or mass form, of all constructed works must be carefully considered. The aspect of the "sky-blotch" of an architectural edifice is very important, for as the day wanes the detail fades and parts become blended, till the members compose but one whole, which, when seen from the east, appears as a solid mass drawn in darkness on the glowing sky; this is the sky-blotch. If the edificeen masseis pleasing, a great point is gained. Indeed, the general contour should have primary consideration. In like manner, the general form of all works of furniture should first be cared for, and every effort should be made at securing to the general mass beauty of shape.
2. After having cared for the general form, the manner in which the work shall be divided into primary and secondary parts must be considered with reference to the laws of proportion, as stated in a former chapter.
3. Detail and enrichment may now be considered; but while these cannot be too excellent, they must still be subordinate in obtrusiveness to the general mass, or to the aspect of the work as a whole.
4. The material of which the object is formed must always be worked in the most natural and appropriate manner.
5. The most convenient or appropriate form for an object should always be chosen, for unless this has been done, no reasonable hope can be entertained that the work will be satisfactory; for the consideration of utility must in all cases precede the consideration of beauty, as we saw in our first chapter.
Having made these few general remarks, we must consider the structure of works of furniture. The material of which we form our furniture is wood. Wood has a "grain," and the strength of any particular piece largely depends upon the direction of its grain. It may be strong if its grain runs parallel with its length, or weak if the grain crosses diagonally, or very weak if the grain crosses transversely. However strong the wood, it becomes comparatively much weaker if the grain crosses the piece; and however weak the wood, it becomes yet weaker if the grain is transverse or diagonal. These considerations lead us to see thatthe grain of the wood must always be parallel with its length whenever strength is required.
For our guidance in the formation of works of furniture, I give the following short table of woods arranged as to their strength:—
Iron-wood, from Jamaica—very strong, bearing great lateral pressure.
Boxof Illawarry, New South Wales—very strong, but not so strong as iron-wood.
Mountain ash, New South Wales—about two-thirds the strength of iron-wood.
Beech—nearly as strong as mountain ash.
Mahogany, from New South Wales—not quite so strong as last.
Black dog-woodof Jamaica—three-fourths as strong as the mahogany just named.
Box-wood, Jamaica—not half as strong as the box of New South Wales.
Cedarof Jamaica—half as strong as the mahogany of New South Wales.[21]
Wood can be got of sufficient length to meet all the requirements of furniture-making, yet we not unfrequently find the arch structurally introduced into furniture, while it is absurd to employ it in wooden construction of any kind. The arch is a most ingenious invention, as it affords a means of spanning a large space with small portions of material, as with small stones, and at the same time gives greatstrength. It is, therefore, of the utmost utility in constructing stone buildings; but in works of furniture, where we have no large spaces to span, and where wood is of the utmost length required, and is stronger than our requirements demand, the use of the arch becomes structurally foolish and absurd. The folly of this mode of structure becomes more apparent when we notice that a wooden arch is always formed of one or two pieces, and not of very small portions, and when we further consider that, in order to the formation of an arch, the wood must be cut across its grain throughout the greater portion of its length, whereby its strength is materially decreased; while if the arch were formed of small pieces of stone great strength would be secured. Nothing can be more absurd than the practice of imitating in one material a mode of construction which is only legitimate in the case of another, and of failing to avail ourselves of the particular mode of utilising a material which secures a maximum of desirable results.
While I protest against the arch when structurally used in furniture, I see no objection to it if used only as a source of beauty, and when so situated as to be free from strain or pressure.
One of the objects which we are frequently called upon to construct is a chair. The chair is, throughout Europe and America, considered as a necessity of every house. So largely used are chairs, that one firm at High Wycombe employs 5,000 hands in making common cane-bottomed chairs alone; and yet we see but few chairs in the market which are well constructed. All chairs having curved frames—whether the curve is in the wood of the back, in the sides of the seat, or in the legs—are constructed on false principles. They are of necessity weak, and being weak are not useful. As they are formed by using wood in a manner which fails to utilise its qualities of strength, these chairs are offensive and absurd. It is true that, through being surrounded by such ill-formed objects from our earliest infancy, the eye often fails to be offended with such works as would offend it were they new to it; but this does not show that they are the less offensive, nor that they are not constructively wrong. Besides, whenever wood is cut across the grain, in order that we get anything approaching the requisite strength, it has to be much thicker and more bulky than would be required were the wood cut with the grain; hence such furniture is unnecessarily heavy and clumsy.
Fig. 26 represents a chair which I have taken the liberty of borrowing from Mr. Eastlake's work on household art.[22]This chair Mr. Eastlake gives as an illustration of good taste in the construction of furniture; but I give it as an illustration of that which is essentially bad and wrong. The legs are weak, being cross-grained throughout, and the mode of uniting the upper and lower portions of the legs (the two semicircles) by a circular boss is defective in the highest degree. Were I sitting in such a chair, I should be afraid to lean to the right or the left, for fear of the chair giving way. Give me a Yorkshire rocking-chair, in preference to one of these, where I know of my insecurity, much as I hate such.
A chair is a stool with a back-rest, and a stool is a board elevated from the ground or floor by supports, the degree of elevation being determined by the length of the legs of the person for whom the seat is made, or by the degree of obliquity which the body and legs are desired to take when the seat is in use. If the seat is to support the body when in an erect sitting posture, about seventeen to eighteen inches will be found a convenient height for the average of persons; but if the legs of the sitter are to take an oblique forward direction, then the seat may be lower.
A stool may consist of a thick piece of wood and of three legs inserted into holes bored in this thick top. If these legs pass to the upper surface of the seat, and are properly wedged in, a useful yet clumsy seat results. In order that the top of the stool be thin and light, it will be necessary that the legs be connected by frames, and it will be well that they beconnected twice, once at the top of each leg, so that the seat may rest upon this frame, and once at least two-thirds of the distance from the top. The frame would now stand alone, and although the seat is formed of thin wood it will not crack, as it is supported all round on the upper frame.
A chair, I have said, is a stool with a back. There is not one chair out of fifty that we find with the back so attached to the seat as to give a maximum of strength. It is usual to make a back leg and one side of the chair-back out of one piece of wood—that is, to continue the back legs up above the seat, and cause them to become the sides of the chair-back. When this is done the wood is almost invariably curved so that the back legs and the chair-back both incline outwards from the seat. There is no objection whatever to the sides of the back and the legs being formed of the one piece, but there is a great objection to either the supports of the back or the legs being formed of cross-grained wood, as much of their strength is thereby sacrificed. Our illustrations (Figs. 27 to 32) will give several modes of constructing chairs such as I think legitimate; but I will ask the reader to think for himself upon the construction of a chair, and especially upon the proper means of giving due support to the back.
I have given, in an axiomatic form, those principles which should guide us in the construction of works of furniture, and endeavoured to impress the necessity of using wood in that manner which is most natural—that is, "working" it with the grain (the manner in which we can most easily work it), and in that way which shall secure the greatest amount of strength with the least expenditure of material. I wish to impress my readers with the importance of these considerations, for they lie at the very root of the successful construction of furniture. If the legs of chairs, or their seat-frames, or the ends or backs of couches, are formed of wood cut across the grain, they must either be thick and clumsy, or weak; but, besides this, the rightly constituted mind can only receive pleasure from the contemplation of works which are wisely formed. Daily contact, as we have before said, with ill-shapedobjects may have more or less deadened our senses, so that we are not so readily offended by deformity and error as we might be; yet, happily for us, directly we seek to separate truth from error, the beautiful from the deformed, reason assists the judgment, and we learn to feel when we are in the presence of the beautiful or in contact with the degraded.
My illustrations will show how I think chairs should be constructed. Fig. 26 is essentially bad, although it has traditional sanction, hence I pass it over without further comment. Fig. 27 is in the manner of an Egyptian chair. It serves to show the careful way in which the Egyptians constructed their works. The curved rails against which the back would rest are the only parts which are not thoroughly correct and satisfactory in a wood structure. Were the curved back members metal, the curvature would be desirable and legitimate. The back of this chair, if the side members were connected by a straight rail, would have immense strength (the backs of some ofourchairs are of the very weakest), and if well made it is a seat which would endure for centuries. Fig. 28 is a chair of my own designing, in which I have sought to give strength to the back by connecting its upper portion with a strong cross-rail of the frame.
Fig. 29 is a chair slightly altered from one in Mr. Eastlake's work on "Household Taste;" as shown in our illustration, it is a correctly formed work. Fig. 30 is an arm-chair in the Greek style, which I have designed. Fig. 31 is a Lady's chair in the Gothic style; Fig. 32, a lady's chair in early Greek. These I have prepared to show different modes of structure; if the legs are fitted to a frame(the seat-frame), as in the early Greek chair just alluded to, they should be very short, as in this instance, or they must be connected by a frame below the seat, as in Figs. 33 and 34. The best general structure is that in which the front legs pass to the level of the upper surface of the seat.
Fig. 33 is a copy of a chair shown by Messrs. Gillow and Co., of Oxford Street, in the last Paris International Exhibition. In many respects it is admirably constructed. The skeleton brackets holding the back to the seat are very desirable adjuncts to light chairs; so are the brackets connecting the legs with the seat-frame, as these strengthen the entire chair. The manner in which the upper rail of the back passes through the side uprights and is "pinned" is good. The chief, and only important, fault in this chair is the bending of the back legs, involving their being cut against the grain of the wood.
Fig. 31 is a chair from Mr. Talbert's very excellent work on "Gothic Furniture." It shows an admirable method of supporting the back. Fig. 35 I have designed as a high-backed lounging chair. With the view of giving strength to the back, I have extended the seat, and arranged a support from this extension to the upper back-rail, and this extension of the seat I have supported by a fifth leg.There is no reason whatever why a chair should have four legs. If three would be better, or five, or any other number, let us use what would be best.[23]
I have now given several illustrations of modes of forming chairs. I might have given many more, but it is not my duty to try and exhaust a subject. What I have to do is simply point out principles, and call attention to facts. It is the reader who must think for himself—first, of the principles and facts which I adduce; secondly, of the illustrations which I give; thirdly, of other works which he may meet with; and fourthly, of further means of producing desirable and satisfactory results than those set forth in my illustrations.
As it cannot be doubted that a well-constructed work, however plain or simple it may be, gives satisfaction to those who behold it—while a work of the most elaborate character fails to satisfy if badly constructed—we shall give a few further illustrations of structure for other articles of furniture, besides chairs, which have become necessary to our mode of life.
Fig. 36 is one of my sketches for Greek furniture, designed for a wealthy client. It was formed of black wood. Here the frame of the seat is first formed,and the legs are inserted beneath it, and let into it, while the wood-work of the end of the couch stands upon it, being inserted into it. This appears to have been the general method with the Greeks of forming their furniture, yet it is not so correct structurally as Fig. 37, another of my sketches, where the end and the leg are formed of one piece of wood. The first formation (that of Fig. 36) would bear any amount of pressure from above, but it is not well calculated for resisting lateral pressure; while the latter would resist this lateral pressure, but would not bear quite the same amount of pressure from above. The latter, however, could bear more weight than would ever be required of it, and would be the more durable piece of furniture.
