THE PENDULUM
To come back to the first position, the head must be tilted backward and the hands drawn to the back of the head. Again the feet will sink and the body be swung back to a perpendicular position with the face above water. One must then stretch the arms at full length behind the head, with the palms upward, gradually inclining the head backward until the legs once more rise to the surface, and the body floats face upward.
Repetition of these movements produce a swinging similar to that of a pendulum. The movements must be accomplished with regularity, at all times keeping the legs straight and together.
SOMERSAULTS
This is one of the easiest and simplest tricks. With very little practise it can be mastered by most ordinary swimmers. Of course, this statement refers to the ordinary somersault, either backward or forward, which is nothing more than a turning over of the body while in the water.
FORWARD SOMERSAULT
In the back somersault the head is tilted back as far as possible, the legs well drawn up, and the arms thrown out horizontally from the shoulders. Then the body is turned on the back and a stroke taken with the arms and hands. As the body is doubled up, this action causes it to turn completely over, the head going under first.
