Should a player make the wrong hoop by mistake, or Croquet a
ball that he is not entitled to Croquet, and the mistake be
discovered before he has made a second stroke, he loses his turn,
and any point so made in error; but if he has made a second stroke
before the discovery, he shall be allowed to continue his break.
In order to prevent the occurrence of the errors noticed in
the above rules (Nos. xv. and xvi), a player is bound, upon being
appealed to, to declare truly what is his next hoop or point in
order, and is entitled to demand of his antagonist what he his
played last, and to insist upon his clip being properly placed.
When clips are used they should be moved by the umpire, or
with his cognisance, at the end of each turn, and their position
shall he conclusive as to the position of the balls in the game.
Should a ball in play be accidentally stopped by the umpire, he
places it where he considers that it would have rolled to. Should it
be stopped by a player, it will rest with the side opposed to that
player to say whether the ball shall remain where it stopped, or be
placed by the umpire, or the stroke be taken again.
If a ball lies within a mallet's length of the boundary, and is
not the playing ball, it must at once be put out three feet at right
angles from the boundary; but if it is the playing ball, it may, at
the discretion of the player, either be put out or played from where
it lies.
If it is found that the height of the boundary interferes with
the stroke, the player may, at the umpire's discretion, bring out
the ball so far as to allow of the free swing of the mallet, and in
taking a Croquet both the balls.
Should a player, in trying to make his hoop, knock a wire out
of the ground with his ball or mallet, the stroke shall be taken
again.
Any player may set upright a peg or hoop except the one next
in order; and that, however loose, awry, or slanting it may be, must
not be altered except by the umpire.
No ball may be moved because of its lying in a hole or on bad
ground, except by the umpire or with his permission.
Where there is no umpire present, permission to move a ball, or
to set up a hoop or peg or other indulgence for which an umpire
would have been appealed to, must be asked of the other side.
