Each team chooses its own
Umpire
who must be a thoroughly competent and impartial girl. The umpires call all fouls except cases coming under the authority of the referee; when the fouls are made by players crossing the field lines, linesmen judge them.
Each umpire makes her own decision independently of the other, but a foul called by one umpire cannot be questioned by the other. The umpire calls time by blowing a whistle when stating a foul and indicating the offender; she reports to the scorer the player at fault and the nature of the foul. The referee appoints the
Scorer
who must keep the score. She must be perfectly neutral. It is the scorer’s duty to notify the referee when a player should be disqualified for any kind of roughness. The referee appoints the
Time-keeper
who must be exact about the time, noting when the game starts, and blowing her whistle at the expiration of the actual playing time in each half previously agreed upon by captains and referee. The time-keeper must take out time when called upon to do so by the referee. The captain is privileged to ask the referee to call time for an injured player or when a difference has occurred between the captain and an official. The half game is generally fifteen minutes, making the entire game thirty minutes, not counting the intermission. The playing time may be shortened to ten minutes for each half or lengthened to twenty for each half. The referee only may order time deducted for necessary stoppages, should any occur during the game. The four
Linesmen
are appointed by the referee; two for each side. These four girls usually stand at the four corners of the centre division, and it is their duty to report if any of the players step on or cross over the dividing lines. Such offences are counted fouls. When the ball happens to be thrown outside the field boundary lines the players are allowed to rush after it, but are not allowed to go beyond the dividing lines when in the field.
