38. If a ball split into separate pieces, another ball may be put down where the largest portion lies, or, if two pieces are apparently of equal size, it may be put where either piece lies, at the option of the player. If a ball crack or become unplayable, the player may change it, on intimating to his opponent his intention to do so.
39. A penalty stroke shall not be counted the stroke of a player, and shall not affect the rotation of play.
40. Should any dispute arise on any point, the players have the right of determining the party or parties to whom the dispute shall be referred; but, should they not agree, either party may refer it to the Green Committee of the green where the dispute occurs, and their decision shall be final. Should the dispute not be covered by the Rules of Golf, the arbiters must decide it by equity.

4. The score shall be kept by a special marker, or by the competitors noting each other's scores. The scores marked shall be checked at the finish of each hole. On completion of the course, the score of the player shall be signed by the person keeping the score and handed to the Secretary.
