THE fate of the door in America has been a curious one, and had the other chief features of the house - such as windows, fireplaces, and stairs - been pursued with the same relentless animosity by architects and decorators, we should no longer be living in houses at all. First, the door was slid into the wall; then even its concealed presence was resented, and it was unhung and replaced by a portiere; while of late it has actually ceased to form a part of house-building, and many recently built houses contain doorways without doors. Even the front door, which might seem to have too valid a reason for existence to be disturbed by the variations of fashion, has lately had to yield its place, in the more pretentious kind of house, to a wrought-iron gateway lined with plate-glass, against which, as a climax of inconsequence, a thick curtain is usually hung.

It is not difficult to explain such architectural vagaries. In general, their origin is to be found in the misapplication of some serviceable feature and its consequent rejection by those who did not understand that it had ceased to be useful only because it was not properly used.

In the matter of doors, such an explanation at once presents itself. During the latter half of the eighteenth century it occurred to some ingenious person that when two adjoining rooms were used for entertaining, and it was necessary to open the doors between them, these doors might be in the way; and to avoid this possibility, a recess was formed in the thickness of the wall, and the door was made to slide into it.

This idea apparently originated in England, for sliding doors, even in the present day, are virtually unknown on the continent; and Isaac Ware, in the book already quoted, speaks of the sliding door as having been used "at the house, late Mr. de Pestre's, near Hanover Square," and adds that "the manner of it there may serve as an example to other builders," showing it to have been a novelty which he thought worthy of imitation.

English taste has never been so sure as that of the Latin races; and it has, moreover, been perpetually modified by a passion for contriving all kinds of supposed "conveniences," which instead of simplifying life not unfrequently tend to complicate it Americans have inherited this trait, and in both countries the architect or upholsterer who can present a new and more intricate way of planning a house or of making a piece of furniture, is more sure of a hearing than he who follows the accepted lines.

It is doubtful if the devices to which so much is sacrificed in English and American house-planning always offer the practical advantages attributed to them. In the case of the sliding door these advantages are certainly open to question, since there is no reason why a door should not open into a room. Under ordinary circumstances, doors should always be kept shut; it is only, as Ware points out, when two adjoining rooms are used for entertaining that it is necessary to leave the door between them open. Now, between two rooms destined for entertaining, a double door (a deux battants) is always preferable to a single one; and as an opening four feet six inches wide is sufficient in such cases, each of the doors will be only two feet three inches wide, and therefore cannot encroach to any serious extent on the floor-space of the room. On the other hand, much has been sacrificed to the supposed "convenience" of the sliding door: first, the decorative effect of a well-panelled door, with hinges, box-locks and handle of finely chiselled bronze; secondly, the privacy of both rooms, since the difficulty of closing a heavy sliding door always leads to its being left open, with the result that two rooms are necessarily used as one.

In fact, the absence of privacy in modern houses is doubtless in part due to the difficulty of closing the doors between the rooms.

The sliding door has led to another abuse in house-planning: the exaggerated widening of the doorway. While doors were hung on hinges, doorways were of necessity restricted to their proper dimensions; but with the introduction of the sliding door, openings eight or ten feet wide became possible. The planning of a house is often modified by a vague idea on the part of its owners that they may wish to give entertainments on a large scale. As a matter of fact, general entertainments are seldom given in a house of average size; and those who plan their houses with a view to such possibilities sacrifice their daily comfort to an event occurring perhaps once a year. But even where many entertainments are to be given large doorways are of little use. Any architect of experience knows that ease of circulation depends far more on the planning of the house and on the position of the openings than on the actual dimensions of the latter. Indeed, two moderate-sized doorways leading from one room to another are of much more use in facilitating the movements of a crowd than one opening ten feet wide.

Sliding doors have been recommended on the ground that their use preserves a greater amount of wall-space; but two doorways of moderate dimensions, properly placed, will preserve as much wall-space as one very large opening and will probably permit a better distribution of panelling and furniture. There was far more wall-space in seventeenth and eighteenth-century rooms than there is in rooms of the same dimensions in the average modern American house; and even where this space was not greater in actual measurement, more furniture could be used, since the openings were always placed with a view to the proper arrangement of what the room was to contain.

According to the best authorities, the height of a well-proportioned doorway should be twice its width; and as the height is necessarily regulated by the stud of the room, it follows that the width varies; but it is obvious that no doorway should be less than six feet high nor less than three feet wide.
