the cue, neither of them has any right to use the butt; but ever}7 person who plays with a cue, may use occasionally a long one, and in such case he may play with the point of a long cue or a mace.
67. If the striker should make his mace or cue touch both balls at the same time, it is deemed a foul stroke, and if discovered by the adversary, he wins nothing for any points he might make by the stroke, and the adversary may break or part the balls.
68. Whenever a foul stroke is made, it is at the option of the adversary either to part the balls, and play from the striking ring, as at the beginning, or, if the balls happen to be in a favourable position for himself, to suffer the preceding striker to score the points ; which the marker is obliged to do, in every case where the balls are not broken.
69. The adversary only is bound to see that the striker plays fair, which if he neglect, the striker wins all the points he may have made by that particular stroke, and the marker is obliged to score them.
70. No person has a right to discover whether a stroke be fair or foul until asked, unless during a four match; and in that case, none but the player or his partner has a right to ask it.
71. Should a dispute arise between the players concerning the fairness of a stroke, the marker alone is authorized to decide, and from his decision there is no appeal : but if he happen to be incompetent, the majority of the disinterested company then present should decide the dispute.
72. Whoever proposes to part the balls, and his adversary agrees, the person who made the proposal loses the lead.
