* * * * * CHAPTER VI BUILDING THE NEST Now that I have told you so many things about the mother-nest, especially about how it is growing all the time, I must tell you more about the many helpers you have who assist in its growth. This they do by providing it with food and by carrying away the waste material. We found the body was composed of many parts or organs, each one of which had its own especial work to do. If any one organ could not perform its work, some other one would have to assist it, but, although the organs are willing to help each other, it would not be fair to make one do more than its share of work, except for a short time. You remember, the stomach had a great deal of work to do in digesting the food or preparing it so it could be taken up by the blood and carried to the womb and all parts of the body. But the stomach does not have to do this all alone. It has several helpers. One set of helpers is the teeth, which cut and grind the food into small particles. In order to do this, they must be kept in very good condition; otherwise, they could not do their work. You know if your mother would let the kitchen knives get dull or rusty, she would be unable to cut the bread, meat and other food materials with them. The same is true of the teeth. We can keep them in good condition by brushing them. It is as important to do this as to wash the dishes. Then, too, we must be careful not to break the teeth by biting nuts and other hard things. Nothing so detracts from a girl's appearance and nothing is more conducive to indigestion than poorly cared for teeth. They should be brushed at least twice daily and the mouth afterwards rinsed with a mild antiseptic solution. The teeth should be thoroughly examined by a good dentist at least every six months.
