Swimming is one of the finest. There is a great deal of difference between swimming and taking a bath in a tub. Some people cannot remain in the water long, but if they have any resistance at all and are active, there will be no bad results. In swimming it is well to take various strokes, swimming on the back, on the side, and on the face. This brings nearly every muscle in the body into play and if the swimmer does not stay in too long it makes him feel fine. If a feeling of chilliness or weariness is experienced, it is time to quit the water, dry off well and take a vigorous dry rub. Swims should always be followed with considerable rubbing. The use of a little olive oil on the body, and especially on the feet, is very grateful. No special rule can be laid down for the duration of a swim, but very thin people should generally not remain in the water more than fifteen minutes, and stout, vigorous ones not over an hour. It is best not to go swimming until two hours have elapsed since the last meal. Every boy and every girl should be taught to swim, for it may be the means of preserving their lives. It is not difficult. For the benefit of those who start the beginners with the rather tedious and tiresome breast stroke, will say that the easiest way to teach swimming is to get the learner to float on his back. I have taught boys to float in as little as three minutes, and after that everything else is easy. When the beginner can float, he can easily start to paddle a little and make some progress. Then he can turn on his side and learn the side stroke, which is one of the best. Then he can turn on the face and learn various strokes. This is not the approved way of learning to swim, but it is the easiest and quickest way. To float simply means to get into balance in the water. It is necessary to arch the body, making the spine concave posteriorly, and bending the neck well backward at first. In the beginning it is a great aid to fill the lungs well and breathe rather shallow. This makes the body light in the water. Tell the beginner that it does not make any difference whether the feet sink or stay up. It is only necessary to keep the face above water while floating. If there is the slightest tendency to sink, bend the neck a little more, putting the head, farther back in the water, instead of raising it, as most of the learners want to do. Remember that the trunk and neck must be kept well arched, the head well back in the water. The moment the beginner doubles up at waist or hips or bends the neck forward, raising the head, he sinks. For speed and fancy swimming professional instruction should be obtained. Swimming is one of the best all-round developers, as well as one of the most pleasant of exercises.
