In the stroke of the legs, you should press against the water with the soles of the feet, not with the toes only; and in that of the hands, you should not only thrust or sweep the water aside, but press it downward also. By these combined move. ments, the resistance afforded by the water is turned to account both in propelling the body and keeping it on the surface. You rise with a rebound from the downward motion, and you are made to shoot forward by the backward impulse of the

These movements, the work of a second in exccution, are preliminary to the stroke itself, which is per. formed in the following manner :- Bring the hands together a few inches below the surface, and a little in advance of the chin, the elbows being bent below the stomach ; the fingers should be quite close together, and the palms slightly concave.

The elbows thus come back to the body, and the hands are brought quickly together as before, the edges only being presented to the water until the hands meet.
While these movements are being performed by the arms, the legs have their part to play as follows:-At the moment when the learner's arms are first thrown forward, as described, he will find his legs rising towards the surface; the knees should then be bent forwards, so that the legs may presently be thrown well out behind; the feet should be kept apart, and the toes turned out. When the hands have made their sweep, the legs are thrown downwards and sideways by a vigorous effort, the stroke of the legs thus alternating with that of the arms, and the
