66. When a person agrees to play with a cue, he must play every ball within his reach with the point thereof; and if he should agree to play with the butt of the cue, he has no right at any time to play with the point without permission. Also, when the parties agree to play _point and point_ of the cue, neither of them has any right to use the _butt_: but every 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 authorised 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. 73. No person in the room has a right to bet more than the odds on a hazard or a game; but if he err through ignorance, he should appeal to the marker, or the table of the odds. Each person who proposes a bet should name the precise sum; and also should be extremely careful not to offer a bet when the striker has taken his aim, or is going to strike; and no bet ought to be proposed on any stroke, that may have any tendency to influence the player. If A propose a bet which is accepted by B, it must be confirmed by A, otherwise it is no bet. If any bets be laid on the hazard, and the striker should lose the game by a miss, at the stroke in question, it cannot be a hazard, the game being out by a miss. In all cases the betters are to abide by the determination of the players, and the betters have a right to demand their money when their game is over. 74. Every person ought to be very attentive, and listen for the stroke, before he opens the door of a billiard-room.
