XXIX. Objects on Green Under no circumstances is any object to be laid on the green, or on a bowl, or on the jack, but it may be dis- played in the hand for guidance of the player. XXX. Players Not Engaged and Where They Stand The players not engaged must stand behind the jack. XXXI. Players Wasting Time During the game the players must succeed one another without unnecessary loss of time. Each bowl shall be played within one minute after the preceding bowl] has come to rest. When complaints of unreasonable delay are made to the umpire, it shall be his duty to award the game to the complainants if satisfied that this rule is being willfully violated. XXXII. Possession of Rink As soon as each bowl stops running, the possession of the rink is transferred to the other party, time being al- lowed for making a toucher. XXXIII. Rink or Team of Players 1. A rink or team shall consist of four players, each playing two bowls and called respectively, according to the order in which they play, lead, second, third and skip. 2. The party to play first shall be determined by toss- ing, or by playing a trial end, the winner to have the choice, or it may be mutually agreed upon by the skips. In all subsequent ends the party which won the previous end shall play first. 3. The leaders play their own bowls alternatively, and so on, each pair of players in succession to the end. 4. If the game is played with three players, the side using only three, shall be penalized one shot for every four ends or fraction thereof, and the lead and second shall each play an extra bowl. 5. If less than three players appear on either side, the game, so far as that Rink, is concerned, shall not proceed, and the rink with which this occurs shall be held as having failed to appear, and shall forfeit the game. 6. The order of playing shall not be changed after the first end has been played. 7. No one shall play until his opponent’s bowl has ceased to run. A bowl so played may be stopped and sent back to be played over again. 8. The last player should remove the mat to the bank. XXXIV. Skips and Their Powers 1. The skips shall have sole charge of their respective rinks, and their instructions must be obeyed by the other players. 2. The skip shall have control of the play, but he may delegate his duty at any time to a substitute, who is usually the third player. 3. As soon as a bowl is greened, the director must retire behind the jack. 4. The two skips shall be judges of all disputed points, and when they agree their decision will be final. If they cannot agree, the point shall be decided by the umpire previously appointed. XXXV. Size of Jack - The jack shall be 2% inches in diameter, and round in shape.
