bar. Thus the vaulter's feet may swing 

 under the bar in the act of springing and 

 pulling up over it. 



The ring vault is done with the flying 

 rings as follows: The under side of the 

 rings in a hanging position must be not 

 higher than 6 ft. 3 in. from the floor. 



The jumping stands are placed in front 

 of the rings in such a position that when 

 the cross-bar is at 8 ft., the under part of 

 the ring when stretched taut will just 

 touch the top of the bar, and then the

 the trunk, hips well up, feet on the near 

 side, and head on the far side of the bar. 

 He then straightens his legs to a momen- 

 tary bent-arm hand balance and then dis- 

 mounts to the mat with a quarter turn. 



In making the spring, his feet must not 

 leave the floor more than once. There 

 must be no stop in the motion of the 

 trunk until the floor is reached. No part 

 of the person may touch the suspended 

 mattress, and no part of the person, ex- 

 cepting the hands, shall touch the bar. 

 The head must not be carried below the 

 lower surface of the bar. In all other 

 respects the rules governing the running 

 high jump apply. 



The one-hand fence vault is the same 

 as the two-hand vault except for the 

 obvious fact that only one hand is allowed 

 on the bar.
