English school games. For example, returning the ball by throwing it out was part of the Rugby and Cheltenham association football rules. Like the modern association football throw-in the direction was not specified. The Sheffield rules instigated the throw in of the ball at right angles by the opposite side to the one that played it into touch. The two handed throw in is part of rugby union football—see "line out". That the first side reaching the ball must throw it out (at right angles, in this case) was part of the Football Association rules and the Rossall rules. The 1863 Cambridge Rules state that "In a match when half the time agreed upon has elapsed, the side shall change goals when the ball is next out of play".
