As the chest begins to
inflate, the body must be allowed to sink under water. At the end of the
inspiration the head should go below the surface. After a couple of
breast strokes under water, turn the head upward. By executing a strong
kick with the legs, the head will rise out of the water. As the body
rises, make one stroke with the arms, and, as soon as the head comes up,
the arms should be recovered to the first position of the breast stroke
and pushed together downward through the water from its level to the
side of the body. Simultaneously, as the hands are moving toward the
body, the legs should be straightened with a sharp kick. This will
force the head and shoulders out of the water.

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.

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 o
