sleeper, with the snow drifts sometimes covering the foot of the bed, with the wintry winds howling about my head in a northeaster, I have been absolutely free from any trace of coughs or colds. Thousands of others will give the same testimony. According to old-fashioned ideas such things would give me my "death of cold." It rarely happens that one begins the practice of sleeping out without becoming a firm believer in it.

One of the children of a friend in Connecticut who had just built a beautiful home was taken ill, and the doctor recommended that the child's bed be moved out on the porch. This was in December. The father also had his own bed moved out to keep the baby company. My friend told me that after the first night he felt like a changed man. He awoke after a refreshing sleep and felt better than he had in years. The whole family soon followed and all the beautiful bedrooms in the house were deserted. The baby got well and stayed well and the doctor's visits are few and far between in that household.

By all means sleep in the open if you can. Of course one must have ample protection from the weather, such as a porch or piazza with a screen or shelter to the north and west. A warm room in which to dress and undress is also absolutely necessary. If your rest is disturbed by cold, as it will probably be until you become accustomed to it and learn the tricks of the outdoor sleeper, you simply need more covers. In winter, the bed should be made up with light summer blankets in place of sheets, which would become very cold. Use, as a night cap, an old sweater or skating cap. A good costume consists of a flannel shirt, woollen drawers, and heavy, lumberman's stockings. With such an outfit and plenty of covers, one can sleep out on the coldest night and never awaken until the winter's sun comes peeping over the hill to tell him that it is time to get up.

Besides fresh air, another important thing in keeping well is to eat slowly and to chew your food thoroughly. Boys and girls often develop a habit of rapid eating because they are anxious to get back to play or to school. Slow eating is largely a matter of habit as well, and while it may seem hard at first it will soon become second nature to us. Remember to chew your food thoroughly. The stomach has no teeth. We have all heard of Mr. Horace Fletcher, that wonderful old man who made himself young again by chewing his food.

There is no fun in life unless we are well, and a sensible boy should realize that his parents' interest in him is for his own benefit. It may seem hard sometimes to be obliged to do without things that we want, but as a rule the judgment of the older people is better than our own. A growing boy will often eat too much candy or too many sweet things and then suffer from his lack of judgment. To fill our stomachs with indigestible food is just as foolish as it would be to put sand in the bearings of our wheel, or to interfere with the delicate adjustment of our watch until it refuses to keep time.

While we play, our muscles are developed, our lungs filled with fresh air and the whole body is made stronger and more vigorous. Some boys play too hard. Over-exertion will sometimes cause a strain on the delicate machinery of the body that will be very serious in after life. The heart is especially subject to the dangers of overstrain in growing boys. We are not all equally strong, and it is no discredit to a boy that he cannot run as far or lift as much as some of his playmates or companions. You all remember the fable of the frog who tried to make himself as big as the ox and finally burst. The idea of exercise is not to try to excel every one in what you do, but to do your best without over-exertion. If a boy has a rugged frame and well developed muscles, it is perfectly natural that he should be superior in most sports to a boy that is delicate or undersized.

To be in good physical condition and to laugh at the doctor we must keep out of doors as much as possible. Gymnasium work of course will help us to build up our strength and develop our muscles, but skill in various acrobatics and gymnastic tricks does not give the clear eye and ruddy cheek of the person whose life is in the open air. Outdoor sports, like tennis, baseball, and horseback riding are far superior to chestweights or Indian clubs as a means of obtaining normal permanent development.

Parents who criticize school or college athletics often forget that the observance of the strict rules of training required from every member of a team is the very best way to keep a boy healthy in mind and body.

Tobacco and alcohol are absolutely prohibited, the kind of food eaten and the hours for retiring are compulsory, and a boy is taught not only to train his muscles but to discipline his mind. Before a candidate is allowed to take active part in the sport for which he is training he must be "in condition," as it is called.

There are a great many rules of health that will help any one to keep well, but the best rule of all is to live a common-sense life and not to think too much about ourselves. Systematic exercises taken daily with setting up motions are very good unless we allow them to become irksome. All indoor exercise should be practised with as much fresh air in the room as possible. It is an excellent plan to face an open window if we practise morning and evening gymnastics.

There are many exercises that can be performed with no apparatus whatever. In all exercises we should practise deep regular breathing until it becomes a habit with us. Most people acquire a faulty habit of breathing and only use a small part of their total lung capacity. Learn to take deep breaths while in the fresh air. After a while it will become a habit.

Just how much muscle a boy should have will depend upon his physical make-up. The gymnasium director in one of our largest colleges, who has spent his whole life in exercise, is a small, slender man whose muscles are not at all prominent and yet they are like steel wires. He has made a life-long study of himself and has developed every muscle in his body. From his appearance he would not be considered a strong man and yet some of the younger athletes weighing fifty pounds more than he, have, in wrestling and feats of strength, found that the man with the largest muscles is not always the best man.

There is one question that every growing boy will have to look squarely in the face and to decide for himself. It is the question of smoking. There is absolutely no question but that smoking is injurious for any one, and in the case of boys who are not yet fully grown positively dangerous. Ask any cigarette smoker you know and he will tell you not to smoke. If you ask him why he does not take his own advice he will possibly explain how the habit has fastened its grip on him, just as the slimy tentacles of some devil fish will wind themselves about a victim struggling in the water, until he is no longer able to escape. A boy may begin to smoke in a spirit of fun or possibly because he thinks it is manly, but more often it is because the "other fellers" are trying it too.

My teacher once gave our school an object lesson in habits which is worth repeating. He called one of the boys to the platform and wound a tiny piece of thread around the boy's wrists. He then told him to break it, which the boy did very easily. The teacher continued to wind more thread until he had so many strands that the boy could break them only with a great effort and finally he could not break them at all. His hands were tied. Just so it is with a habit. The first, second, or tenth time may be easy to break, but we shall finally get so many tiny threads that our hands are tied. We have acquired a habit. Don't be a fool. Don't smoke cigarettes.

Walking is one of the most healthful forms of exercise. It may seem unnecessary to devote much space to a subject that every one thinks they know all about, but the fact is that, with trolley cars, automobiles, and horses, a great many persons have almost lost the ability to
