Swimming Like a Porpoise
This trick, very interesting and pretty, is quite mirth-provoking to the onlooker, especially if indulged in by a number of swimmers. Unlike the vast majority of tricks performed in the water, it does not call for ability to float well, the only qualification being that one must be a fairly good swimmer.
Begin by lying flat on the water with the face downward. Then take a deep inspiration after having cleared the lungs. 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.
