meets, but it would be more appropriate 

 for boys than the vault for height. The 

 action is much like the above styles except 

 that there is no necessity for getting so 

 much of a "lift." 



Vaulting Rules 



The height of the bar at starting and at 

 each successive elevation is determined 

 by the field judges. 



Each competitor is allowed three jumps 

 at each height, and the competitor who 

 fails at the third attempt is disqualified.

"balks" are always counted as a trial jump. 



Any competitor is allowed to dig a hole 

 not more than 1 ft. in diameter at the take- 

 off, in which to plant his pole. 



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 



A competitor may commence at any 

 height above the minimum height. He 

 must, however, jump at every following 

 height until he has forfeited his right to 

 compete further. 



The vault is made over a bar resting 

 on pegs. 



As soon as a competitor has left the 

 ground for the purpose of making a jump, 

 the jump is counted as a trial. 



A line is drawn 15 ft. in front of the bar 

 and parallel therewith, to be known as the 

 balk line, and stepping over such a line, 

 or such line extended, in any attempt is 

 counted as a "balk." Two successive 



Poles may have a binding, but must not 

 have any further support for the hands. 



If the uprights are moved at all they 

 must not be changed more than 2 ft. in 

 any direction, and not more than one hole 

 may be made by a competitor. The take- 

 off ground about the jump must be level. 



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.
