Jumping.
While all jumping may be done in one pit, where the space is available it is better to have one pit for the high jumps, one for the running broad, one for hop, step and jump, another for the pole vault.
The pits should be soft. All pits are made the same way but differ in size. The earth should be dug up to a depth of at least a foot and a half. If ground is hard, pits should be deeper. This soft dug-up earth should be equally mixed with sand or sawdust or both. Pits should be kept well raked up and not allowed to become packed.
For the high jump the pit should be wide, at least eight feet in width and six or seven feet long. For high jumping, two adjustable standards and a bamboo or thin cross-bar are required. These standards are placed six feet apart, directly opposite each other in a straight line. The standards are perforated by little round holes into which the pegs (not more than 3 inches long) are inserted to hold the cross-bar. There should be a runway or approach of at least twenty yards. There is no take-off.
For the running broad jump there is a runway—cinder track, if possible—20 to 30 yards in length, 3 feet in width. A take-off is sunk, marking division between runway and pit. This is a planed joist, 5 inches wide, sunk into ground so that top is on a level with runway, and painted white. The pit should be at least 25 feet long and about 6 feet wide. This may also be used for standing broad. The pit for the hop, step and jump is constructed in the same way.
For the pole vault the uprights should be 10 feet apart, placed opposite each other. There is a runway—cinder track, if possible—about 20 or 25 yards long, 10 feet wide. Between the two uprights a plank 16 inches deep should be sunk, 2 inches of which should be above ground level. In front of plank, in center, a hole 5 or 6 inches deep should be dug.
