I’m not sure of the year but this photo shows a game of Bat and Trap being played/watched on The Level.

The game of Bat and Trap is played between two teams of up to eight players. At any one time, one team is batting and the other is bowling. The game involves placing a heavy solid-rubber ball, similar to a lacrosse ball, on one end of a “trap”, which is a low wooden box 22 inches (560 mm) long, 5 inches wide, and 5 inches (130 mm) high, on top of which is a simple see-saw mechanism. Each player in turn on the batting side hits the opposite end of the see-saw lever (the “striker”) with his or her bat, so as to propel the ball into the air, and then, using the same bat, attempts to hit the ball between two 7-foot (2.1 m) high posts situated 21 yards (19 m) away and 13 feet 6 inches (4.11 m) apart at the other end of the playing area, or “pitch”.(Courtesy of Wikipedia)
