11. No player is allowed to interfere with an opponent unless such an opponent is within four feet of the ball, except when the ball is within the goal section, when indiscriminate tackling will be allowed in the goal section, the goal section to be a space of four feet by eight feet within the goal-line and between two parallel lines drawn at right angles to the goal-line and distant two feet from either end of the goal.

12. Upon a goal being gained, the opposite teams shall go to their own end of the tank, and the ball shall be thrown by the referee into the center and play started as at beginning of game.

13. Each team shall have two judges, one at each goal-line, who, upon a goal being made, shall notify the referee and announce the same.

Only in case the judges disagree shall the referee have power to decide whether a goal be fairly made or not.

14. The referee shall decide all fouls, and if in his opinion a player commits a foul he shall caution the team for the first offense and give the opponents a free trial for goal at each succeeding foul.

A free trial for goal will be given by lining up three backs of the defending team within the 4-foot line and giving three forwards of the opposing team the ball on the 15-foot line, when they may try for a goal until a goal is scored or the ball goes outside the 15-foot line. Only three men from each side will be allowed within the 15-foot line, until the ball goes outside that line or a goal is scored.

Fouls.—It shall be foul to tackle an opponent if the ball is not within four feet of him or to hold him by any part of his costume. It shall be a foul to cross the 4-foot line ahead of the ball, unless forced over by an opponent, or to hang on to the sides of the tank except for the purpose of resting.

Unnecessary rough work may, within the discrimination of the referee, either be counted a foul or the referee may put the offender out of the tank until a goal is scored or the half ends.
