Recent examination of school children in various cities in England and America has revealed a state of physical ill-being most deplorable in the present, and horrifying to contemplate for its future results. One has only to keep one's eyes open in passing the streets to become aware of the physical deterioration of thousands of the wage-earners. One has only to listen to the housewife's complaints of inefficiency, lack of strength among the housemaids, to realize that the world's work is not being well done in so far as it depends upon human hands. This loss of efficiency is usually attributed to insufficient food and long hours, but it is at least an open question if housing conditions are not the more potent factor not only in the case of the very poor, but even in the case of the family having an income of $2000 a year. Life in a boarding-house adapted from the use by one family to that of five or six without increase of bathing and ventilating conveniences, with old-style plumbing, cannot be mentally or bodily invigorating. The house cannot be said to be a place of safety so long as the "great white plague" lurks in every dark corner--tuberculosis, colds, influenza, etc., fasten themselves upon its occupants. Explorers exposed to extremes of weather do not thus suffer. The dark, damp house incubates the germs. But homes there must be: places of safety for children, of refuge for elders. Men will marry and women may keep house. How shall it be managed so as to be in harmony with present-day demands? Certainly not by ignoring the difficulties. Progress in any direction does not come through wringing of hands and deploring the decadence of the present generation. President Roosevelt's advice is to bring up boys and girls to overcome obstacles, not to ignore them. Let the educated, intelligent young people join in devising a way to surmount this obstacle as the engineers of 1890 invented new ways of crossing impassable gorges and "impossible" mountain ranges. The writer has no ready-prepared panacea to offer. Patent medicine is not the remedy. This kind cometh out only by fasting and prayer. A long course of diet is needed to cure a chronic disease. This little volume is intended merely as a spur to the imagination of the indolent student, to arouse him to the mental effort required to deal with the readjustment of ideas to conditions before it is too late. It is no exaggeration to say that the social well-being of the community is threatened. The habits of years are broken up; sad to say, the middle-aged will suffer unrelieved, but the young can be incited to grapple with the situation and hew out for themselves a way through. Certain elements in the problem will be touched upon in the following pages as a result of much going to and fro in the "most favored land on earth." Certain questions will be raised as to what constitutes a home and a shelter for the family in the twentieth-century sense of both family and shelter.
