This is a transition from front swimming, in which the attitude and motions of the feet are still the same, but those of the hands very different. One arm, the right for instance, is lifted entirely out of the water, thrust forward as much as possible, and, when at the utmost stretch, let fall, with the hand hollowed, into the water, which it grasps or pulls towards the swimmer in its return transversely towards the opposite arm-pit. While the right arm is thus stretched forth, the left, with the hand expanded, describes a small circle to sustain the body (Plate XXVIII. fig. 1); and, while the right arm pulls towards the swimmer, the left, in a widely-described circle, is carried rapidly under the breast, towards the hip. (Plate XXVIII. fig. 2.) When the left arm has completed these movements, it, in its turn, is lifted from the water, stretched forward, and pulled back,--the right arm describing first the smaller, then the larger circle. The feet make their movements during the describing of the larger circle. The thrust requires much practice; but, when well acquired, it not only relieves the swimmer, but enables him to make great advance in the water, and is applicable to cases where rapidity is required for a short distance. SPRINGING. Some swimmers, at every stroke, raise not only their neck and shoulders, but breast and body, out of the water. This, when habitual, exhausts without any useful purpose. As an occasional effort, however, it maybe useful in seizing objects above; and it may then best be performed by the swimmer drawing his feet as close as possible under his body, stretching his hands forward, and, with both feet and hands, striking the water strongly, so as to throw himself out of it as high as the hips. ONE-ARM SWIMMING. Here the swimmer must be more erect than usual, hold his head more backward, and use the legs and arm more quickly and powerfully. The arm, at its full extent, must be struck out rather across the body, and brought down before, and the breast kept inflated. This mode of swimming is best adapted for assisting persons who are drowning, and should be frequently practised--the learner carrying first under, then over the water, a weight of a few pounds. In assisting drowning persons, however, great care should be taken to avoid being caught hold of by them. They should be approached from behind, and driven before, or drawn after the swimmer to the shore, by the intervention, if possible, of anything that may be at hand, and if nothing be at hand, by means of their hair; and they should, if possible, be got on their backs. Should they attempt to seize the swimmer, he must cast them loose immediately; and, if seized, drop them to the bottom, when they will endeavour to rise to the surface. Two swimmers treading water may assist a drowning person by seizing him, one under each arm, and carrying him along with his head above water, and his body and limbs stretched out and motionless.
