nning at the take-off, and ending in the soft ground on
the other side at exactly the same distance from the base-line of the
posts. No. 3 shows him still rising from the ground, his right foot
giving the direction of the leap. The muscles of the arms and back are
now just coming into play to raise the torso and the left leg--and all
the time the eye is firmly fixed on the bar. In No. 4 the right foot is
just passing over the handkerchief, and the arms and back are seen
straining with the exertion of bringing up the left leg. Notice that
muscle of the neck. It connects with the muscles of the side and
abdomen, and these harden like steel to force the quick motion that has
to be made to lift that side of the body. The strain on this neck muscle
and the working of the back and arms are even better displayed in No. 5,
where the left leg is almost up, and is about to clear the bar.
Considerable practice is required for this motion, because it has to be
done very quickly. The left foot has to be brought in very close to the
right thigh, and yet the sharp spikes must be kept from tearing the
flesh. Note how the eye is constantly on the bar.

In the next picture, No. 6, the bar has been cleared, the whole body is
over, and the right leg has dropped. It is now no more used, except as a
balance to the body, the entire work of the jump, as before stated,
being done with the left leg. The jumper's eye is still fixed on the
bar, and not until he is well over it, as shown in No. 7, does he remove
his gaze. As he clears the stick his back muscles give a twist to his
flying form, and his right arm thrown into the air aids him in turning,
so that he will fall facing the bar. The left leg has now passed the
right, and is making ready to sustain the weight of the body on landing,
while the right is thrust slightly backward to sustain a proper
equilibrium. The strain on the back and arms is relaxed. In No. 8 he is
just about to land, and the camera has given us a beautiful display of
the looseness of the arm muscles, showing the right arm still in the air
and about to drop as soon as the feet strike the ground. The body is
lying along the curve of the semicircle through which the jump has been
made.

The bar in all these pictures was at 5 ft. 8 in., and each photograph
necessitated a separate jump. This alone is enough to show in what
excellent form the young athlete worked, for a kinetoscope could not
have caught his separate actions in
