Tuberculosis or Consumption.—This disease is so common and deadly that twenty persons die from it in our country every hour. It is caused by tiny germs ([Fig. 63]) which lodge in the lungs, glands, bones, or other parts of the body, where they give off poison and hurt the tissues. We take these germs into the body with dust or food, and also by putting to the lips a drinking cup or other things used by a consumptive. Generally the germs will not grow in a strong body, even when they have lodged there.

Preventing Consumption.—Living in poorly lighted houses without much fresh air, working in dusty rooms, using much strong drink and tobacco, eating poor food, losing sleep, neglecting a cough, and taking little or no outdoor exercise weaken the body so that the consumption germs can grow in it. Deep breathing, sitting and walking erect, living in rooms with sunshine, sleeping with the windows open eight or nine hours every night, and eating good food will prevent one from taking consumption and will often cure the disease. Persons with this sickness give out the germs in their spit, which should be caught in a cup and burned.

The Hookworm Disease.—This is a sickness affecting thousands of persons in the South. It is caused by tiny worms half as large as a pin hanging fast to the lining of the bowels. The worm is sometimes called the lazy germ because it destroys the red blood cells and makes the body feel weak and lazy. Children with these worms grow slowly, have a dry skin, and a swollen abdomen with a tender spot below the stomach.

The disease is easily cured by a physician, but it is better to prevent it by killing the germs in the waste from the bowels. For directions, address the Department of Health at the capital of your state. If the germs reach the ground they crawl around and may get into the well, and enter the body again with the drinking water. Generally, however, the worms enter through the skin of those going barefooted, and are carried by the blood to the lungs. From here they go up the windpipe to the throat, and then down the gullet to the bowels. It is their entrance through the skin that causes ground itch or dew itch. Wearing shoes will help prevent the disease.

A Strong Body Wins.—Nobody wants to be weak and sickly. Most all of us could keep well if we would try in the right way to keep the body strong.
