Climate and Soil.--The soil on which one lives is a matter of primary importance; it may be a matter of life or death for a weakly person, but it is important for every one. First, as regards the subsoil on which a house is built. If this be clay, or impervious rock, then no possible system of drainage can make the site a dry one; this condition of affairs will be very bad indeed for health. No house should be built on such a soil if at all possible to avoid it. Light open gravel and sand, as subsoil, make the very best health conditions. The surface soil is also important. If this be such that streets and garden walks dry quickly after rain, you have elements of health; if they remain long wet, then you have elements of unhealthiness. If the soil be right, then the climate is to be considered. The mere situation of two houses, only half a mile apart, will make all the difference in this, and should be carefully watched. A house sheltered on the south and west, exposed to the north and east, is badly situated; the opposite exposure is usually good. Plenty of sun should fall upon the house all day, and on all sides, if that be possible. Yet it must be seen that no hollow or stagnant air be chosen; it is nearly as bad as stagnant water, for in mild winds, dryness of soil and air, and abundant sun, lie much virtue for health and healing. Clothing.--Clothing should be light yet warm, and sufficiently free so as not to interfere with bodily movements. The clothing next the skin should, we think, be linen, as being more porous and absorbent than wool (_see_ Underwear). No woman who values her health should submit to any tight lacing. The organs of the body require every inch of space for the proper performance of their functions, and if they are unduly squeezed many serious complaints may result. Besides the skin is a breathing organ, and it is most important that air should readily reach it (_see_ Tight Lacing). Long trains should not be worn, as they are most effective agents for sweeping up germs of diphtheria, consumption, etc. Skirts should not be hung from the waist, but from the shoulders, and should be light in weight. Tight boots and high heels are both to be condemned. The practice of wearing mufflers, or any tight wrapping round the neck region, is injurious and enervating to this part of the body. The sailor, though exposed to more rough weather than any other class, is free from throat or chest trouble, and can stand both heat and cold better than soldiers. Sailors are, indeed, the only sensibly dressed men in our country. Soldiers, in their tight-fitting tunic and stiff collars, are the worst. They constantly die of heat and apoplexy, when farm labourers doing more work are nothing the worse.
