23. _Boundary interfering with Stroke._--If it be found that the height of the boundary interferes with the stroke, the striker, with the sanction of the umpire or the adversary, may bring in the balls a longer distance than three feet, so as to allow a free swing of the mallet. Balls so brought in must be moved in the line of aim, and placed at the same relative distance. 24. _Dead Boundary._--If, in taking croquet, the striker send his own ball, or the ball croqueted, off the ground, he loses the remainder of his turn, unless (_a_) with the playing ball he make a roquet, or (_b_) the croqueted ball be caused to make a point in order (the striker's ball not passing the boundary). 25. _Balls touched by Adversary._--Should a ball when rolling, except it be in hand, be touched, diverted from its course, or stopped by an adversary, the striker may elect whether he will take the stroke again, or whether the ball shall remain where it stopped, or be placed where in the judgment of the umpire or the striker it would have rolled to. 26. _Balls diverted or stopped by Umpire._--Should a ball be diverted from its course or stopped by an umpire, he is to place it where he considers it would have rolled to. 27. _Foul Strokes._--If a player make a foul stroke he loses the remainder of his turn, and any point or roquet made by such stroke does not count. Balls moved by a foul stroke are to remain where they lie, or be replaced at the option of the adversary. If the foul be made when taking croquet, and the adversary elect to have the balls replaced, they must be replaced in contact as they stood when the croquet was taken. The following are foul strokes: (_a_) To strike with the mallet another ball instead of or besides one's own, in making the stroke. (_b_) To spoon--_i.e._, to push a ball without an audible knock. (_c_) To strike a ball twice distinctly in the same stroke (except in the case of rolling two balls together if only one player use india-rubber). (_d_) To touch, stop, or divert the course of a ball when in play and rolling, whether this be done by the striker or his partner. (_e_) To allow a ball to touch the mallet [or any part of the player's person] in rebounding from a peg or wire. (_f_) To move a ball which lies close to a peg or wire by striking the peg or wire [_i.e._, to touch with the mallet a wire or peg in making the stroke]. (_g_) To press a ball round a peg or wire (crushing stroke). (_h_) To play a stroke after roquet without taking croquet. (_i_) To fail to move both balls in taking croquet. (_k_) To croquet a ball which the striker is not entitled to croquet. (_l_) To knock a wire of the hoop out of the ground when making a stroke.
