ON CASES IN WHICH THE MARKER MUST REPLACE THE BALLS, IF CALLED ON, AS NEARLY AS POSSIBLE IN THEIR FORMER POSITION.

1. In the case mentioned in the [5th paragraph] of the preceding rule.

2. Where any of the balls, when at rest, are moved by accident.

3. Where any of the balls, while rolling, are suddenly obstructed either by accident or design on the part of any person other than the player. In this case, the marker, if so requested by the players or referee, shall place the interrupted ball as nearly as possible in the situation which it would apparently have occupied had it not been stopped.

4. Where the cue-ball, resting on the edge of a pocket, drops into it before the striker has time to play.

5. Where the object-ball, in a similar position, is rolled back into the pocket by any of the ordinary vibrations of the table or atmosphere.

6. In all the cases aforementioned where it is specified that in consequence of a foul stroke the player’s opponent shall have the option either of playing at the balls as they are, or causing them to be replaced by the marker.

7. When either or both of the red balls are pocketed, or forced off the table, it is the marker’s duty to spot them before another stroke is played—except (the game being played is caroms and pockets) the spot appropriate to either be occupied by one of the playing balls, in which case the red one must be kept in hand until its position is uncovered.

8. If, after playing a ball, the player should attempt to obstruct or accelerate its progress by striking it again, blowing at it, or any other means, his opponent may either play at the balls as they stand, or call upon the referee or marker to replace them in the position they would otherwise have occupied.

9. It is the duty of each player to see that a ball is properly spotted before the next stroke is made. As in the case where a player is in hand, a claim of foul, after the cue-ball has been struck in the one instance, and the red ball disturbed in another, cannot be entertained. All claims to the effect that the red ball is not on its spot, or that the striker’s ball is not inside the “string” when he is about to play after having been in hand, should be made before the stroke is played, as it can seldom be decided after the stroke, whether there was any ground for the claim.
