Any number may play that is convenient to the place. A player should be able to cover about ten by ten feet.Should any player during play touch the net, it puts the ball out of play and counts against his side. Should any player catch or hold for an instant the ball, it is out of play and counts for the opposite side. Should the ball strike any object other than the floor and bound back into play, it is still in play. To dribble the ball is to carry it all the time, keeping it bouncing. When dribbling the ball no player shall cross the dribbling line, this putting the ball out of play and counting against him. Any player except the captain, addressing the umpire or casting any slurring remarks at him or any of the players on the opposite side, may be disqualified, and his side be compelled to play the game without him or a substitute, or forfeit the same.
