For the very excellent reason that corners and angles are unsanitary, there are to be no more of them in the construction of houses and office buildings of the better class. They are being built with "round" corners; even the ceiling and walls, and floor and walls, meet in a curve,--no square crevice or corner where dust or germs can gather. If we add moisture to a sunless spot, we have the ideal environment for germs to breed and flourish in. There is always moisture or humidity in the air if the altitude is low, and if it is near the ocean, or any large body of water, the moisture is relatively greater. For this reason we send patients with pulmonary disease to the mountains, where the altitude is much higher, where there is no moisture, and consequently where there are practically no germs. We cannot move our homes to the mountains, however, so what must we do to get rid of the moisture and the germs where we are compelled to live? What do we do with the family wash when it is wet? We hang it up in the yard, in the sun and in the breeze, because we know from experience that the wind and the sun soon dry anything wet. They do more; they freshen everything, so that anything exposed to the sun and air smells fresh and sweet and is fresh and sweet and pure. So to make our homes sweet and fresh and dry we must chase the stale air away, and the moisture with it, by opening our windows and letting in the sunlight and the breeze, every day, and for as long as possible every day. Open windows and sunlight and fresh air,--all you can get,--this is the song of health, the joy of life, the only agents that will keep the eager, busy, little white blood cell healthy and willing and alert. This is the reason you must keep the windows of your bedrooms open at night, as well as by day, so you and your children will get fresh, pure, sweet air, and not stale, moist, germ-laden air to breathe. FACTS ABOUT TUBERCULOSIS Tuberculosis, or consumption, is a disease of poor air, dusty quarters, insufficient nourishment, and, above all, of ignorance with regard to its dangers and what we now know of the possibilities of its cure. The more we know about it the better chance there is to cure it, and better still, prevent it. Not very long ago the death rate from consumption was one in six, that is, every sixth person who died in this country died as a result of tuberculosis in some form. It is now about one in eight. This is a remarkable decrease--about one-third of its former ratio of victims are now spared. Not so very long ago the disease was regarded as practically fatal; now it is classified as one of the eminently curable diseases. The universal dissemination of this knowledge will do much to rob the "Great White Plague" of its terrors.
