The ordinary process of painting in dyes upon a wool or linen fabric woven in tapestry method, and fixing the colour with heat, enables the painter - if a true tapestry subject is chosen and tapestry effects carefully studied - to produce really effective and good things, and this opens a much larger field to the woman decorator than the ordinary unstudied shams which have thrown what might become in time a large and useful art-industry into neglect and disrepute, I have seen the walls of a library hung with Siberian linen, stained in landscape design in the old blues and greens which give tapestry its decorative value, and found it a delightful wall-covering. Indeed we may lay it down as a principle in decoration that while we may use and adapt any decorative effect we must not attempt to make it pass for the thing which suggested the effect.

Coarse and carefully woven linens, used as I have indicated, are really far better than old tapestries for modern houses, because the design can be adapted to the specific purpose and the texture itself can be easily cleaned and is more appropriate to the close walls and less airy rooms of this century.

For costly wall-decoration, leather is another of the substances which have had a past of pomp and magnificence, and carries with it, in addition to beauty, a suggestion of the art of a race. Spanish leather, with its stamping and gilding, is quite as costly a wall covering as antique or modern tapestry, and far more indestructible. Perhaps it is needlessly durable as a mere vehicle for decoration. At all events Japanese artists and artisans seem to be of this opinion, and have transferred the same kind of decoration to heavy paper, where for some occult reason - although strongly simulating leather - it seems not only not objectionable, but even meritorious. This is because it simply transfers an artistic method from a costly substance, to another which is less so, and the fact may even have some weight that paper is a product of human manufacture, instead of human appropriation of animal life, for surely sentiment has its influence in decoration as in other arts.

Wood panelling is also a form of interior treatment which has come to us by inheritance from the past as well as by right of natural possession.

It has a richness and sober dignity of effect which commends it in large or small interiors, in halls, libraries, and dining-rooms, whether they are public or private; devoted to grand functions, or to the constantly recurring uses of domesticity. Wood is so beautiful a substance in itself, and lends itself to so many processes of ornamentation, that hardly too much can be said of its appropriateness for interior decoration. From the two extremes of plain pine panellings cut into squares or parallelograms by machinery, and covered with paint in tints to match door and window casings, to the most elaborate carvings which back the Cathedral stalls or seats of ecclesiastical dignity, it is always beautiful and generally appropriate in use and effect, and that can hardly be said of any other substance. There are wainscotted rooms in old houses in Newport, where, under the accumulated paint of one or two centuries, great panels of old Spanish mahogany can still be found, not much the worse for their long eclipse. Such rooms, in the original brilliancy of colour and polish, with their parallel shadings of mahogany-red reflecting back the firelight from tiled chimney-places and scattering the play of dancing flame, must have had a beauty of colour hard to match in this day of sober oak and painted wainscottings.

PAINTED CANVAS FRIEZE.

BUCKRAM FRIEZE FOR DINING-ROOM.

One of the lessons gained by experience in treatment of house interiors, is that plain, flat tints give apparent size to small rooms, and that a satisfying effect in large ones can be gained by variation of tint or surface; also, that in a bedroom or other small room apparent size will be gained by using a wall covering which is light rather than dark. Some difference of tone there must be in large plain surfaces which lie within the level of the eye; or the monotony of a room becomes fatiguing. A plain, painted wall may, it is true, be broken by pictures, or cabinets, or bits of china; anything in short which will throw parts of it into shadow, and illumine other parts with gilded reflections; but even then there will be long, plain spaces above the picture or cabinet line, where blank monotony of tone will be fatal to the general effect of the room.

It is in this upper space, upon a plain painted wall, that a broad line of flat decoration should occur, but on a wall hung with paper or cloth, it is by no means necessary.

Damasked cloths, where the design is shown by the direction of woven threads, are particularly effective and satisfactory as wall-coverings. The soft surface is luxurious to the imagination, and the play of light and shadow upon the warp and woof interests the eye, although there is no actual change of colour.

Too much stress can hardly be laid upon the variation of tone in wall-surfaces, since the four walls stand for the atmosphere of a room. Tone means quality of colour. It may be light or dark, or of any tint, or variations of tint, but the quality of it must be soft and charitable, instead of harsh and uncompromising.

Almost the best of modern inventions for inexpensive wall-coverings are found in what are called the ingrain papers. These have a variable surface, without reflections, and make not only a soft and impalpable colour effect, but, on account of their want of reflection, are good backgrounds for pictures.

In these papers the colour is produced by a mixture in the mass of paper pulp of atoms of varying tint, which are combined in the substance and make one general tint resulting from the mixture of several. In canvases and textiles, which are a more expensive method of producing almost the same mixed effect, the minute points of brilliance of threads in light and darkness of threads in shadow, combine to produce softness of tone, impossible to pigment because it has but one plain surface, unrelieved by breaking up into light and shadow.

Variation, produced by minute differences, which affect each other and which the eye blends into a general tone, produce quality. It is at the same time soft and brilliant, and is really a popular adaptation of the philosophy of impressionist painters, whose small dabs of pure colour placed in close juxtaposition and fused into one tone by the eye, give the purity and vibration of colour which distinguishes work of that school.

Some skilful painters can stipple one tone upon another so as to produce the same brilliant softness of effect, and when this can be done, oil-colour upon plaster is the best of all treatment for bedrooms since it fulfils all the sanitary and other conditions so necessary in sleeping-rooms. The same effect may be produced if the walls are of rough instead of smooth plaster, so that the small inequalities of surface give light and shadow as in textiles; upon such surfaces a pleasant tint in flat colour is always good. Painted burlaps and certain Japanese papers prepared with what may be called a textile or canvas surface give the same effect, and indeed quality of tint and tone is far more easily obtained in wall-coverings or applied materials than in paint, because in most wall-coverings there are variations of tint produced in the very substance of the material.

This matter of variation without contrast in wall-surface, is one of the most important in house decoration, and has led to the increased use of textiles in houses where artistic effects have been carefully studied and are considered of importance.

Of course wall-paper must continue to be the chief means of wall-covering, on account of its cheapness, and because it is the readiest means of sheathing a plaster surface; and a continuous demand for papers of good and nearly uniform colour, and the sort of inconspicuous design which fits them for modest interiors will have the effect of increasing the manufacture of desirable and artistic things.

In the meantime one should carehilly avoid the violently coloured papers which are made only to sell; materials which catch the eye of the inexperienced and tempt them into the buying of things which are productive of lasting unrest. It is in the nature of positive masses and strongly contrasting colours to produce this effect.

If one is unfortunate enough to occupy a room of which the walls are covered with one of these glaring designs, and circumstances prevent a radical change, the simplest expedient is to cover the whole surface with a kalsomine or chalk-wash, of some agreeable tint. This will dry in an hour or two and present a nearly uniform surface, in which the printed design of the paper, if it appears at all, will be a mere suggestion. Papers where the design is carried in colour only a few shades darker than the background, are also safe, and - if the design is a good one - often very desirable for halls and dining-rooms. In skilfully printed papers of the sort the design often has the effect of a mere shadow-play of form.

Of course in the infinite varieties of use and the numberless variations of personal taste, there are, and should be, innumerable differences in application of both colour and materials to interiors. There are differences in the use of rooms which may make a sense of perfect seclusion desirable, as, for instance, in libraries, or rooms used exclusively for evening gatherings of the family. In such semi-private rooms the treatment should give a sense of close family life rather than space, while in drawing-rooms it should be exactly the reverse, and this effect is easily secured by com-petent use of colour.
