it may be
re-dropped without penalty. The penalty for a breach of this Rule shall
be the loss of the hole.

16. When the balls lie within six inches of each other on the
putting-green, or within a club length of each other through the green
or in a hazard (the distance to be measured from their nearest points),
the ball nearer the hole may, at the option of either the player or the
opponent, be lifted until the other is played, and shall then be
replaced as near as possible to the place where it lay. If the ball
further from the hole be moved in so doing, or in measuring the
distance, it shall be replaced without penalty. If the lie of the lifted
ball be altered by the player in playing, the ball may be placed in a
lie as nearly as possible similar to that from which it was lifted, but
not nearer the hole.

17. Any loose impediments may be removed from the putting-green,
irrespective of the position of the player's ball. The opponent's ball
may not be moved except as provided for by the immediately preceding
Rule. If the player's ball move after any loose impediment lying within
six inches of it has been touched by the player, his partner, or either
of their caddies, the penalty shall be one stroke.

18. When the ball is on the putting-green, the player or his caddie may
remove (but not press down) sand, earth, dung, worm-casts, mole-hills,
snow, or ice lying around the hole or in the line of his putt. This
shall be done by brushing lightly with the hand only across the putt and
not along it. Dung may be removed by a club, but the club must not be
laid with more than its own weight upon the ground. The line of the putt
must not be touched, except with the club immediately in front of the
ball, in the act of addressing it, or as above authorised. The penalty
for a breach of this Rule is the loss of the hole.

19. When the ball is on the putting-green, no mark shall be placed, nor
line drawn as a guide. The line of the putt may be pointed out by the
player's caddie, his partner, or his partner's caddie, but the person
doing so must not touch the ground.

The player's caddie, his partner, or his partner's caddie, may stand at
the hole, but no player nor caddie shall endeavour, by moving or
otherwise, to influence the action of the wind upon the ball.

The penalty for a breach of this Rule is the loss of the hole.
