Thus the word "home," in the human mind, touches the spring of a large complex group of ideas and sentiments, some older than humanity, some recent enough for us to trace their birth, some as true and inalienable as any other laws of life, some as false and unnecessary as any others of mankind's mistakes. It does not follow that all the earliest ones are right for us to-day, because they were right for our remote predecessors, or that those later introduced are therefore wrong.

What is called for is a clear knowledge of the course of evolution of this earliest institution and an understanding of the reasons for its changes, that we may discriminate to-day between that which is vital and permanent in home life and that which is unessential and injurious. We may follow without difficulty the evolution of each and all the essential constituents of home, mark the introduction of non-essentials, show the evils resultant from forced retention of earlier forms; in a word, we may study the evolution of the home precisely as we study that of any other form of life.

Take that primal requisite of safety and shelter which seems to underlie all others, a place where the occupant may be protected from the weather and its enemies. This motive of home-making governs the nest-builder, the burrow-digger, the selector of caves; it dominates the insect, the animal, the savage, and the modern architect. Dangers change, and the home must change to suit the danger. So after the caves were found insufficient, the lake-dwellers built above the water, safe when the bridge was in. The drawbridge as an element of safety lingered long, even when an artificial moat must needs be made for lack of lake. When the principal danger is cold, as in Arctic regions, the home is built thick and small; when it is heat, we build thick and large; when it is dampness, we choose high ground, elevate the home, lay drains; when it is wind, we seek a sheltered slope, or if there is no slope, plant trees as a wind-break to protect the home, or, in the worst cases, make a "cyclone cellar."

The gradual development of our careful plastering and glazing, our methods of heating, of carpeting and curtaining, comes along this line of security and shelter, modified always by humanity's great enemy, conservatism. In these mechanical details, as in deeper issues, free adaptation to changed conditions is hindered by our invariable effort to maintain older habits. Older habits are most dear to the aged, and as the aged have always most controlled the home, that institution is peculiarly slow to respond to the kindling influence of changed condition. The Chaldeans built of brick for years unnumbered, because clay was their only building material. When they spread into Assyria, where stone was plenty, they continued calmly putting up great palaces of sunbaked brick,—mere adobe,—and each new king left the cracking terraces of his predecessor's pride and built another equally ephemeral. The influence of our ancestors has dominated the home more than it has any other human institution, and the influence of our ancestors is necessarily retroactive.

In the gathering currents of our present-day social evolution, and especially in this country where progress is not feared, this heavy undertow is being somewhat overcome. Things move so rapidly now that one life counts the changes, there is at last a sense of motion in human affairs, and so these healthful processes of change can have free way. The dangers to be met to-day by the home-builder are far different from those of ancient times, and, like most of our troubles, are largely of our own making. Earthquake and tidal wave still govern our choice of place and material somewhat, and climate of course always, but fire is the chief element of danger in our cities, and next to fire the greatest danger in the home is its own dirt.

The savage was dirty in his habits, from our point of view, but he lived in a clean world large enough to hold his little contribution of bones and ashes, and he did not defile his own tent with detritus of any sort. We, in our far larger homes, with our far more elaborate processes of living, and with our ancient system of confining women to the home entirely, have evolved a continuous accumulation of waste matter in the home. The effort temporarily to remove this waste is one of the main lines of domestic industry; the effort to produce it is the other.

Just as we may watch the course of evolution from a tiny transparent cell, absorbing some contiguous particle of food and eliminating its microscopic residuum of waste, up to the elaborate group of alimentary processes which make up so large a proportion of our complex physiology; so we may watch the evolution of these home processes from the simple gnawing of bones and tossing them in a heap of the cave-dweller, to the ten-course luncheon with its painted menu. In different nations the result varies, each nation assumes its methods to be right, and, so assuming, labours on to meet its supposed needs, to fulfil its local ambitions and duties as it apprehends them. And in no nation does it occur to the inhabitants to measure their habits and customs by the effect on life, health, happiness, and character.

The line of comfort may be followed in its growth like the line of safety. At first anything to keep the wind and rain off was comfortable—any snug hole to help retain the heat of the little animal. Then that old ABC of all later luxury, the bed, appeared—something soft between you and the rock—something dry between you and the ground. So on and on, as ease grew exquisite and skill increased, till we robbed the eider duck and stripped the goose to make down-heaps for our tender flesh to lie on, and so to the costly modern mattress. The ground, the stamped clay floor, the floor of brick, of stone, of wood; the rushes and the sand; the rug—a mere hide once and now the woven miracle of years of labour in the East, or gaudy carpet of the West—so runs that line of growth. Always the simple beginning, and its natural development under the laws of progress to more and more refinement and profusion. Always the essential changes that follow changed conditions, and always the downward pull of inviolate home-tradition, to hold back evolution when it could.

See it in furnishing: A stone or block of wood to sit on, a hide to lie on, a shelf to put the food on. See that block of wood change under your eyes and crawl up history on its forthcoming legs—a stool, a chair, a sofa, a settee, and now the endless ranks of sittable furniture wherewith we fill the home to keep ourselves from the floor withal. And these be-stuffed, be-springed, and upholstered till it would seem as if all humanity were newly whipped. It is much more tiresome to stand than to walk. If you are confined at home you cannot walk much—therefore you must sit—especially if your task be a stationary one. So, to the home-bound woman came much sitting, and much sitting called for ever softer seats, and to the wholly home-bound harem women even sitting is too strenuous; there you find cushions and more cushions and eternal lying down. A long way this from the strong bones, hard muscles, and free movement of the sturdy squaw, and yet a sure product of evolution with certain modifications of religious and social thought.

Our homes, thanks to other ideas and habits, are not thus ultra-cushioned; our women can still sit up, most of the time, preferring a stuffed chair. And among the more normal working classes, still largely and blessedly predominant, neither the sitting nor the stuffing is so evident. A woman who does the work in an ordinary home seldom sits down, and when she does any chair feels good.
