21. Either side is entitled to have the flag-stick removed when
approaching the hole, but if a player's ball strike the flag-stick
which has been so removed by himself, or his partner, or either of
their caddies, his side shall lose the hole. If the ball rest against
the flag-stick when in the hole, the player shall be entitled to remove
the stick, and if the ball fall in, it shall be deemed as having been
holed out at the last stroke. If the player's ball knock in the
opponent's ball, the latter shall be deemed as having been holed out at
the last stroke. If the player's ball move the opponent's ball, the
opponent, if he choose, may replace it, but this must be done before
another stroke is played. If the player's ball stop on the spot formerly
occupied by the opponent's ball, and the opponent declare his intention
to replace, the player shall first play another stroke, after which the
opponent shall replace and play his ball. If the opponent's ball lie on
the edge of the hole, the player, after holing out, may knock it away,
claiming the hole if holing at the like, and the half if holing at the
odd, provided that the player's ball does not strike the opponent's ball
and set it in motion. If after the player's ball is in the hole, the
player neglect to knock away the opponent's ball, and it fall in also,
the opponent shall be deemed to have holed out at his last stroke.

22. If a ball _in motion_ be stopped or deflected by any agency outside
the match, or by the forecaddie, the ball must be played from where it
lies, and the occurrence submitted to as a "rub of the green." If a ball
lodge in anything moving, a ball shall be dropped as near as possible to
the place where the object was when the ball lodged in it, without
penalty. If a ball _at rest_ be displaced by any agency outside the
match, excepting wind, the player shall drop a ball as near as possible
to the place where it lay, without penalty. On the putting-green the
ball shall be replaced by hand, without penalty.

23. If the player's ball strike, or be moved by an opponent or an
opponent's caddie or clubs, the opponent shall lose the hole.

24. When a player has holed out and his opponent has been left with a
putt for the half, nothing that the player can do shall deprive him of
the half which he has already gained.
