comfortable inside, have very little "strength," or food value, in them, and simply warm you up and stir up your nerves without doing you any real good at all. A cracker or a single piece of bread or one large saucer of cereal has only about one fourth of the strength in it that you will need for playing or studying until noontime. So after you have started to school with a breakfast like this, about the middle of the morning you begin to feel tired and empty and cross, and wonder what is the matter with yourself.
Children of your age are growing so fast that they need plenty of good, wholesome food. They get so hungry that they want to be eating all the time. For "grown-ups" three times a day is enough; but for you children, whose bodies use up the food so fast, it is well to take also a piece of bread and butter, or two or three cookies, or a glass of milk with some crackers, in the middle of the morning and again about the middle of the afternoon. It will not hurt your appetite for dinner or supper, and you won't be wanting to "pick" at cake and candy and pickles all day long.
How does eating keep you alive and make you grow? Eating is somewhat like mending a fire. You put wood or coal on the fire, and it keeps burning and giving out heat; but if you do not put fresh fuel on, the fire soon goes out. Just so, putting food into your body feeds the "body fires" and keeps you warm, and at the same time makes you grow. Of course the "body fires" are not just like those you see burning in the stove: there are no flames. But there is burning going on, just the same.
The food you put into your body must be made soft and pulpy before it can burn in your muscles. Now you can guess what your teeth are for. They chop, crush, and grind the food; and the tongue rolls it over and over and mixes it with the moisture in your mouth, until it is almost like very thick soup. Then you make a little motion with your tongue and throat, and down it goes.
[Illustration: THE FOOD TUBE
Note the arrows. This is the trip made by every mouthful of food.]
Where does it go? It is passed down a tube that we call the food tube. While I tell you about it, you can look at the picture and then try to draw it yourself.
The food goes quickly down the first part of the tube until it comes to a part much larger than the rest, which we call the stomach. Here it is churned about for a long time, and the meat you have eaten is melted, or dissolved. Then the food goes on into the next part of the tube, which has become narrow again. This lower part, which is about twenty-five feet long, is coiled up just below the waist, between the large bones that you can feel on each side of your body. These coils of the food tube, we call the bowels.
Winding all around the stomach and bowels are tiny branching pipes full of blood. They look somewhat like the creepers on ivy, or the tendrils on grapevines. These suck out the melted food from the bowels. They take what the body can use, and carry it away in the blood to all parts of the body. This is the fuel that keeps the "body fires" going. The tougher parts of the food, which the body cannot use, are carried down to the lower end of the bowels and pushed out by strong muscles.
This waste should be passed out from the body once every day and at the same time each day. In the morning after breakfast is perhaps the best time. If you do not get rid of it every day, it makes poisons, which go into your blood and soon make you very sick indeed. You must keep clean inside as well as outside.

GOING TO SCHOOL
I. GETTING READY
As soon as you have finished breakfast, and brushed your teeth and gone to the toilet, you are ready to run out of doors to play, if you have plenty of time, or, if not, to start for school.
Doesn't it seem a nuisance, in winter time, to have to put on a coat and overshoes and a cap or a hood, and sometimes leggings and mittens, too? But your mothers know what is best for you; and when you are young and growing fast, you have so much more surface in proportion to your weight than when you are grown up, that you lose heat from the blood
