We live in an atmosphere filled with dust, besides, there is constantly escaping from our clothes, dust and dirt of various kinds. These things, with the oil of the skin, plug up a portion of the pores, so that the effete, dirty matter cannot escape. Keeping these poisons in the system, not only produces pimples upon the face, and discoloration of the skin, but dullness and heaviness of the whole system. The mind becomes foggy, the spirits low, the muscles stiff and sore, the breath and perspiration offensive, the whole system unclean. Those portions of our skins that we cover with clothes are somewhat difficult to keep clean. Roll up your sleeve when your arm is perspiring, and rub the skin hard with your naked hand. You will be surprised at the rolls of dirt which the rubbing will bring away. You may rub some minutes in the same place, before the little rolls will stop coming. This dirt is held by the oil of the skin. IMPORTANCE OF SOAP. Nothing cleans the skin like soap. Wetting the skin every morning with simple water, and wiping it off, will not keep it clean. Such simple water baths contribute to cleanliness, and are useful; but the cleanest condition of the surface cannot be secured by such means. DETAILS OF THE BATH. Let me tell you just how to manage your daily baths. You must have a bathing mat, which you can procure at any rubber store. It consists of a circular, thin rubber sheet, four or five feet in diameter, with the edge turned up two inches. This, during the day, has been folded up and thrown aside. When you want to bathe, spread it out, and you have a tub four feet in diameter, and just as good as though the sides were two feet high. This is all the bath-tub you need. Perhaps I ought to say, that if it is not convenient to purchase one of these at a rubber store, you can make one with a large piece of oil-cloth, by sewing a rope into its edge. Of course you must have a wash-bowl with two or three quarts of water. Next, a pair of bathing mittens,--simple bags,--loosely fitting your hands. These are made of the ends of a worn-out crass or Turkish towel, though any thick linen will do. Now with a piece of good soap,--it matters little what kind,--you are ready.
