Double Somersaults
As this trick requires two swimmers, it makes necessary a great deal more practise. To begin, the swimmers stand on the bottom of the pool, one in front of the other. The forward swimmer throws out his arms at a right angle with the body, even with the shoulders, and spreads his legs until his feet are about twelve inches apart. Then the second swimmer, after taking a deep breath, dives under water and places his head between the legs of the other, bending his legs backward until they come close to the head of the forward swimmer, who in turn tilts his head backward so that it may be grasped by the legs of the other.
When in this position, the swimmers begin to turn backward, using the arms the same is in the backward (single) somersault. The head of each swimmer should be tilted well backward. As the head of the forward swimmer disappears below the surface, the head of the other should appear. After several turns the grip of the legs may be released and the swimmers rise to the surface in their original positions.
