The tendency of many modern decorators to sacrifice composition to detail, and to neglect the observance of proportion between ornament and structure, makes the adaptation of Renaissance stucco designs a somewhat hazardous undertaking; but the very care required to preserve the scale and to accentuate the general lines of the design affords good training in the true principles of composition.

Equally well suited to modern use are the designs in arabesque with which, in France, Bérain and his followers painted the ceilings of small rooms during the Louis XIV period (see [Plate XXVI]). With the opening of the eighteenth century the Bérain arabesques, animated by the touch of Watteau, Huet and J.-B. Leprince, blossomed into trellis-like designs alive with birds and monkeys, Chinese mandarins balancing umbrellas, and nymphs and shepherdesses under slender classical ruins. Side by side with the monumental work of such artists as Lebrun and Lesueur, Coypel, Vouet and Natoire, this light style of composition was always in favor for the decoration of petits appartements: the most famous painters of the day did not think it beneath them to furnish designs for such purposes (see [Plate XXVII]).

In moderate-sized rooms which are to be decorated in a simple and inexpensive manner, a plain plaster ceiling with well-designed cornice is preferable to any device for producing showy effects at small cost. It may be laid down as a general rule in house-decoration that what must be done cheaply should be done simply. It is better to pay for the best plastering than to use a cheaper quality and then to cover the cracks with lincrusta or ceiling-paper. This is true of all such expedients: let the fundamental work be good in design and quality and the want of ornament will not be felt.

In America the return to a more substantial way of building and the tendency to discard wood for brick or stone whenever possible will doubtless lead in time to the use of brick, stone or marble floors. These floors, associated in the minds of most Americans with shivering expeditions through damp Italian palaces, are in reality perfectly suited to the dry American climate, and even the most anæmic person could hardly object to brick or marble covered by heavy rugs.

The inlaid marble floors of the Italian palaces, whether composed of square or diamond-shaped blocks, or decorated with a large design in different colors, are unsurpassed in beauty; while in high-studded rooms where there is little pattern on the walls and a small amount of furniture, elaborately designed mosaic floors with sweeping arabesques and geometrical figures are of great decorative value.

Floors of these substances have the merit of being not only more architectural in character, more solid and durable, but also easier to keep clean. This should especially commend them to the hygienically-minded American housekeeper, since floors that may be washed are better suited to our climate than those which must be covered with a nailed-down carpet.

Next in merit to brick or marble comes the parquet of oak or other hard wood; but even this looks inadequate in rooms of great architectural importance. In ball-rooms a hard-wood floor is generally regarded as a necessity; but in vestibule, staircase, dining-room or saloon, marble is superior to anything else. The design of the parquet floor should be simple and unobtrusive. The French, who brought this branch of floor-laying to perfection, would never have tolerated the crudely contrasted woods that make the modern parquet so aggressive. Like the walls of a room, the floor is a background: it should not furnish pattern, but set off whatever is placed upon it. The perspective effects dear to the modern floor-designer are the climax of extravagance. A floor should not only be, but appear to be, a perfectly level surface, without simulated bosses or concavities.

In choosing rugs and carpets the subject of design should be carefully studied. The Oriental carpet-designers have always surpassed their European rivals. The patterns of Eastern rugs are invariably well composed, with skilfully conventionalized figures in flat unshaded colors. Even the Oriental rug of the present day is well drawn; but the colors used by Eastern manufacturers since the introduction of aniline dyes are so discordant that these rugs are inferior to most modern European carpets.
