The less we alter our method of advancing in the water from what is habitual to us on shore, the more easy do we find a continued exercise of it. The most important consequence of this is, that, though a person swimming in an upright posture advances more slowly, he is able to continue his course much longer; and certainly nothing can be more beneficial to a swimmer than whatever tends to husband his strength, and to enable him to remain long in the water with safety. Bernardi’s primary object is to enable the pupil to float in an upright posture, and to feel confidence in the buoyancy of his body. He accordingly supports the pupil under the shoulders until he floats tranquilly with the head and part of the neck above the surface, the arms being stretched out horizontally under water. From time to time, the supporting arm is removed, but again restored, so as never to suffer the head to sink, which would disturb the growing confidence, and give rise to efforts destructive of the success of the lesson. In this early stage, the unsteadiness of the body is the chief difficulty to be overcome. The head is the great regulator of our movements in water. Its smallest inclination to either side instantly operates on the whole body; and, if not corrected, throws it into a horizontal posture. The pupil must, therefore, restore any disturbance of equilibrium by a cautious movement of the head alone in an opposite direction. This first lesson being familiarized by practice, he is taught the use of the legs and arms for balancing the body in the water. One leg being stretched forward, the other backward, and the arms laterally, he soon finds himself steadily sustained, and independent of further aid in floating. When these first steps have been gained, the sweeping semicircular motion of the arms is shown. This is practised slowly, without motion forwards, until attained with precision. After this, a slight inclination of the body from the upright position occasions its advancing. The motion of striking with the legs is added in the same measured manner; so that the pupil is not perplexed by the acquisition of more than one thing at a time. In this method, the motions of both arms and legs differ from those we have so carefully described, only in so far as they are modified by a more upright position. It is optional, therefore, with the reader, to practise either method. The general principles of both are now before him.
