SWIMMING LIKE A PORPOISE
A sudden inclination of the head toward the chest will assist the body in rolling over, when the back and legs will become visible after the head is again under water, the legs being the last to sink. By carefully regulating the breathing, this movement can be effected a number of times.
THE PENDULUM
This is another very clever trick, requiring considerable practise; the main essential is ability to float. The "pendulum" is primarily a balancing feat, a well-inflated chest being the main requisite.
The body should first be allowed to float on the water, with the arms stretched out beyond the head and in line with the body. The head must be thrown well back while the body is kept perfectly still. Then take a deep inhalation, bringing the head well forward, as if to look at the feet. Simultaneously with this movement draw hands toward the head. These combined movements will cause the body to sink, and thus assume a perpendicular position in the water.
When the body has assumed a perpendicular position, the arms must be brought to the front of the body, stretched well out, and at the same time the head must be sunk between the arms until the face and arms lie on the surface of the water. When the arms and head are down, the feet will rise and the body float on the surface with the face down.
