[Illustration: Pressing out the air in the lungs. Allowing the lungs to fill themselves. THE NEW METHOD OF ARTIFICIAL BREATHING Devised by a celebrated physiologist, Professor Schaefer of Edinburgh, and now being adopted by life-saving stations and crews everywhere.] You may sometime be called upon to save another person from drowning. In such a case, as in every emergency, a cool head is the chief thing. Make up your mind just what you are going to do before you do _anything_,--then do it _quickly_! If no one is near enough to hear your shouts for help, and no boat is at hand, if possible throw, or push, to the one in the water a plank or board or something that will float, and he will instinctively grasp it. If you are thrown into the water with a person that can't swim, grasp his collar or hair, and hold him at arm's length, to prevent his dragging you under, until help arrives, or until you can tow him to safety. Boys and girls, after they have learned to swim, may well practice rescuing each other, so as to be prepared for such accidents. Artificial Breathing. The best way to revive a person who has been under water and is apparently drowned, is to turn him right over upon his chest on the ground, or other level surface, turning the face to one side so that the nose and mouth will be clear of the ground. Then, kneeling astride of the legs, as shown in the picture, place both hands on the small of the back and throw your weight forward, so as to press out the air in the lungs. Count three, then swing backward, lifting the hands, and allow the lungs to fill themselves with air for three seconds, then again plunge forward and force the air out of the lungs and again lift your weight and allow the air to flow in for three seconds. Keep up this swinging backward and forward about ten or twelve times a minute. This is the newest and by far the most effective way--in fact the only real way--of keeping up artificial breathing. It is very, very seldom that any one can be revived after he has been under water for more than five minutes,--indeed, after three minutes,--but this method will save all who can possibly be saved. So perfect a substitute for breathing is it that if any one of you will lie down in this position upon his face, and allow some one else to press up and down on the small of his back after this fashion, ten or twelve times a minute, he will find that, without making any effort of his own to breathe, this pumping will draw enough air into his lungs to keep him quite comfortable for half an hour.
