Pushball is a game played by two sides on a field usually 140 yards (130 m) long and 50 yards (46 m) wide, with a ball 6 feet (1.8 m) in diameter and 50 pounds (23 kg) in weight. Occasionally, much heavier balls were used. The sides usually number eleven each, there being five forwards, two left-wings, two right-wings and two goal-keepers. The goals consist of two upright posts 18 feet (5.5 m) high and 20 feet (6.1 m) apart with a crossbar 7 feet (2.1 m) from the ground. The game lasts for two periods with an intermission. Pushing the ball under the bar counts 5 points; lifting or throwing it over the bar counts 8. A touchdown behind goal for safety counts 2 to the attacking side.
