A competitor must not, in the moment that he makes a jump, or after leaving the ground, place his lower hand above the upper one or move the upper hand higher up on the pole.

���Plant the pole lightly by thrusting the end into the hole just before the left foot strikes the take- off and at the same time throw the arms forward with the left close up to the right exactly as above

The uprights should be at least 12 ft. apart.

All measurements are made perpendicu- larly from the ground to the upper side of the bar where it is lowest.

In the pole vault, if in making a trial the competitor's pole is broken, it is not counted as a trial.
