John Cameron, Association Football and How to Play It (1908)
“ When a free kick has been awarded, the kicker's opponents shall not approach within six yards of the ball, unless they are standing on their own goal line. The ball must at least be rolled over before it shall be considered played, i.e., it must make a complete cuit or travel the distance of its circumference. The kicker shall not play the ball a second time until it has been played by another player. ”
