THE DOUBLE THRUST.

In the performance of this the arm is thrust forwards, backwards, and again forwards without dipping into the water; in the meantime the stretched-forth arm describes two circles before it begins the larger one.

TO SWIM LIKE A DOG.

[Ill.u.s.tration]

In this motion each hand and foot is used alternately as a dog uses them when swimming, as the term implies. The hands are alternately drawn towards the chin in a compressed form, and then expanded and slightly hollowed, with fingers close, and as they strike the water the feet are likewise drawn towards the belly, and struck backwards with a kind of kick. This mode of swimming is of use to relieve the swimmer from time to time when going a distance.

THE MILL.

The swimmer lays himself on his back and contracts himself so that the knees are brought almost to the chin, and while one of the hands keeps the equilibrium by describing circles, the other continues working. Thus the body is kept turning round more or less rapidly.

THE WHEEL BACKWARDS AND FORWARDS.

In the _forward wheel_ the hands are put as far backwards as possible, and so pressed against the water that the head is impelled under the surface, and the feet, by a pressure of the hands in a contrary direction, are rapidly flung above the head, which in this manner is rapidly brought again to the surface.

In the _backward wheel_ the swimmer lies upon his back, he contracts himself, the hands, stretched forward as far as possible, describe rapidly small circles, the feet rise, and as the point of equilibrium has been brought as near as possible to the feet, the head sinks and the feet are thrown over.

TO SWIM WITH ONE HAND.

The learner to do this swims on one side, keeps his feet somewhat deeply _sunk_, while the arm which in the meantime ought to work is kept quiet--and might even be taken out of the water. It is a good practice of strength to carry, first under and then over the water, a weight of four or eight pounds.

HAND OVER HAND SWIMMING.

[Ill.u.s.tration]

In this process, the right hand is lifted out of the water from behind, swung forwards through the air with a kind of circular sweep to the extent of its reach forward, then dropped into the water edgeways, and immediately turned, with the palm a little hollowed, downwards, the body being at the same time thrown a little on one side, and the right leg struck out backwards to its full extent. The hand descends towards the thigh, and then pa.s.ses upwards through the water in a kind of curve towards the surface. The left hand and leg perform a similar movement alternately with the right, and the measure of progression attained by these combined similar movements is very considerable.

BALANCING.

[Ill.u.s.tration]

When the swimmer has obtained ease and confidence in the water, he will find many things easy which before he deemed impossible. Balancing is one of these. To perform it he has only, when out of his depth, to fall gently back with his chin elevated to a line pa.s.sing exactly through the centre of his body from the chin to the toes, then, folding his arms and remaining perfectly motionless, he may suspend himself perpendicularly: but if he should extend his arms backwards, and pa.s.s them gradually beyond his head, his toes, tips of his knees, abdomen, and part of his chest, with the whole of his face will appear, and he will be balanced and float horizontally without the slightest motion.

THE CRAMP.

The cramp generally proceeds from acidity of the bowels, arising from a bad state of the stomach, or from the effects of the cold water on the muscular system. Some persons are very subject to it on slight occasions, and such persons will do well never to go out of their depth.

But should a tolerable swimmer be seized with the cramp, he should not be frightened, but the moment the cramp is felt in the foot or leg, strike out that foot or leg with the heel elongated, and the toes drawn upwards towards the shin-bone, never minding any little pain it may occasion, as he need not fear breaking a bone, muscle, or tendon. Should this not succeed, he should throw himself on his back, and float quietly, and paddle himself gently to the sh.o.r.e. He may also swim with his hands like a dog, and practise any of the motions of the upper part of the body for keeping his head above water till a.s.sistance arrives.

SAVING FROM DANGER.

Above all things the good swimmer should be anxious to save life, and to rescue those who are in danger, _without himself becoming the victim, as it often happens_. The following rules are highly important to be observed. The swimmer must avoid approaching the drowning person in front, in order that he may not be grasped by him; for whatever a drowning person seizes, he holds with convulsive force, and it is no easy matter to get disentangled from his grasp; therefore he should seize him from behind, and let go of him immediately if the other turns towards him. His best way is to impel him before him to the sh.o.r.e, or to draw him behind; if the s.p.a.ce to be pa.s.sed be too great, he should seize him by the foot and drag him, turning him on his back. If the drowning person should seize him, there is no alternative for the swimmer than to drop him at once to the bottom of the water, and there to wrestle with his antagonist; the drowning man, by a kind of instinct to regain the surface, when drawn down to the bottom, usually quits his prey, particularly if the diver attacks him there with all his power.

For two swimmers the labour is easier, because they can mutually relieve each other. If the drowning person has still some presence of mind remaining, they will then seize him one under _one arm, and the other under the other_, and without any great effort in treading water, bring him along with his head above water, while they enjoin him to keep himself stretched out and as much as possible without motion.

SPORTS AND FEATS IN SWIMMING.

1. _The Float._--In this sport one swimmer lays himself horizontally on the back, with the feet stretched out, the hands pressed close to the body, and the head raised forward. The other swimmer takes hold of him by the extremity of the feet, and, swimming with one hand, impels him forward. The first remains motionless.

2. _The Plank._--One swimmer lays himself horizontally as before, another lays hold of him with both his hands, immediately above the ancle, and pulls him obliquely into the water, while he extends himself and impels himself forward; thus both the swimmers drop rapidly the one over the other.

3. _The Pickaback Spring._--One swimmer treads the water, the other swims near him behind, places his hands upon the shoulders of the first, and presses him down. He then leaves his hold, and puts his feet upon his shoulders, and, flinging himself out of the water, pushes the first towards the bottom. Now he treads water, and the first performs the part of the second, and so on.

4. _The Shove._--Two swimmers place themselves horizontally on their backs, the legs are strongly extended, and the soles of the feet bear against each other; each impels forward with all his power, and he who succeeds in pushing back the other is the conqueror.

5. _The Wrestle._--Two swimmers place themselves opposite to each other, tread water and hold their right hands in the air; the question is, who shall first force his opponent under the water by pressure. Only the head of the adversary is to be touched, and that only by pressure.

BERNARDI'S SYSTEM OF UPRIGHT SWIMMING.

This system has been introduced into many of the naval and military colleges on the Continent, and has for its distinguishing characteristic the swimming in an upright position. The first object is to teach the pupil how to float in an upright posture. He is taught the use of his legs and arms for balancing the body in water, and then to imitate as much as possible the movement of the limbs upon land. He then pays great attention to the movements of the head, the smallest inclination of which on either side instantly operates on the whole body. He next learns the method of using his arms and legs; and for this purpose is directed to stretch his arms laterally on each side, and then, by placing one foot forward and the other backward, he is enabled to float easily and progress slowly. The same circular sweep of the hands and the action of the legs are next practised, and the feet should be struck downwards and a little forwards, when the movement of the arms is the reverse of the old methods of swimming. The young swimmer who has gone through the various courses laid down by us, will easily comprehend the principle of Bernardi's system, and as easily carry it out if he will take the trouble. It is much less fatiguing than the old plan, and can be carried on for a longer period, and is of invaluable service to troops who may have to cross rivers or d.y.k.es, and to all who may be exposed to the various accidents of flood and field.

THE PRUSSIAN SYSTEM OF PFUEL.

The best of all methods for teaching swimming is that originally introduced by General Pfuel into the Prussian swimming-schools. By this method a person may be made a very good swimmer in a very short time.

The apparatus for teaching consists of a hempen girdle five inches in width, of a rope from five to six fathoms in length, of a pole eight feet long, and a horizontal rail fixed about three-and-a-half feet above the platform, on which the teacher stands, to rest the pole on.

The depth of the water in the place chosen for swimming should, if possible, be not less than eight feet, and the clearest and calmest water should be selected. The pupil wears drawers, fastened by a band above the hips and covering about half the thighs. He is now placed near the horizontal rail, his hands resting upon it, while the teacher shows him the motion which he will have to make with his legs in the water.

This he does by guiding the motion of one leg while the pupil rests, on the other. This motion we shall explain presently.

The swimming girdle, about five inches wide, is now placed round the pupil's breast, so that its upper edge rests on the chest, without getting tight. The teacher takes the rope, which is fastened to the ring of the girdle, in his hand, and directs the pupil to leap into the water, keeping the legs straight and close together, and the arms close to the body, and, what is very important, to breathe out through the nose as soon as his head rises above the water, instead of breathing in first, as every man naturally does after a suspension of breath. The object of this is to prevent the water from getting into the throat, which produces an unpleasant feeling of choking and headache. This expiration soon becomes perfectly natural to the swimmers.

The pupil is next invited to leap. He is drawn up immediately by the rope, pulled to the ladder, and allowed to gain confidence gradually.

The rope is now fastened by a noose to the end of the pole, the other end of it being kept in the hand of the teacher; the pole is rested on the horizontal rail, and the pupil stretches himself horizontally on the water, where he remains, supported by the pole. Next the arms are extended stiffly forward, the hands clasped, the chin touches the water; the legs are also stiffly stretched out, the heels being together, the feet turned out, and the toes drawn up. This horizontal position is important, and must be executed correctly. No limb is permitted to be relaxed.

The movement of the limbs is now taught; that of the legs is taught first. The teacher first says, loudly and slowly, "One;" when the legs are slowly drawn under the body; at the same time the knees are separated to the greatest possible distance, the spine is bent downwards, and the toe kept outwards. The teacher then says briskly, "Two;" upon which the legs are stiffly stretched out with a moderate degree of quickness, while the heels are separated, and the legs describe the widest possible angle, the toes being contracted and kept outwards. The teacher then says quickly, "Three;" upon which the legs, with the knees held stiffly, are quickly brought together, and thus the original position is again obtained.

The point at which the motions "two" and "three" join are the most important, because it is the object to receive as large and compact a wedge of water between the legs as possible; so that when the legs are brought together their action upon this wedge may urge the body forward.

In ordinary cases of swimming, the hands are not used to propel, but merely to a.s.sist in keeping on the surface. By degrees, therefore, "two"

and "three" are counted in quick succession, and the pupil is taught to extend the legs as widely as possible. After some time, what was done under the heads "two" and "three" is done when "two" is called out. When the teacher sees that the pupil is able to propel himself with ease, which he frequently acquires the power of doing in the first lesson, and that he performs the motions already mentioned with regularity, he teaches the motions of the hands, which must not be allowed to sink, as they are much disposed to do while the motion of the legs is practised.

The motion of the hands consists of two parts. When the teacher says "One," the hands, which were held with the palms together, are opened, laid horizontally an inch or two under water, and the arms are extended till they form an angle of 90; then the elbow is bent, and the hands are brought up to the chin, having described an arch downward and upward; the lower part of the thumb touches the chin, the palms being together. When the teacher says "Two," the arms are quickly stretched forward, and thus the original horizontal position is regained. The legs remain stiffly extended during the motion of the hands. If the motion of the hands is carefully and correctly performed, the legs and arms are moved together; so that while the teacher says "One," the pupil performs the first motion of the hands and legs; when he says "Two," the second and third motions of the feet, and the second of the hands.

As soon as the teacher perceives that the pupil begins to support himself, he slackens the rope a little, and instantly straightens it if the pupil is about to sink. When the pupil can swim about ten strokes in succession, he is released from the pole, but not from the rope. When he can swim about fifty strokes, he is released from the rope too; but the teacher remains near him with a long pole until he can swim 150 strokes in succession, so that, should he sink, the pole is immediately held out to him. After this he may swim in the area of the school, under the superintendence of the teacher, until he proves that he can swim half-an-hour in succession, so that, should he sink, the pole is immediately held out to him; he is then considered fit to be left to himself.
