11. All stones which roll over, or come to rest on their sides or tops, shall be removed from the ice.

Note.—So weird a phenomenon seems impossible, but then curlers are very weird also. Incredible as it may sound, it is quite possible to put down one of these great granite buns with the handle in the centre of its top crust so unevenly that, after a drunken wobble or two, it turns right over amid howls and shouts and execrations. Probably you could not do it if you tried, any more than you could cut a golf-ball smartly to square leg when you mean to go quite straight. But these distressing feats are known to occur, without the player having had the smallest desire to accomplish them. The traditional penalty for thus mishandling a stone is “drinks all round.” The present writer has never seen a stone come to rest on its side, but “credit, quia impossibile.”

13. Players, during the course of each head, shall be arranged along the sides, but well off the centre of the rink.... Skips only shall be entitled to stand within the seven-foot circle.

14.... Should a player play a wrong stone, any of the players may stop it while running; but if the mistake is not noticed till the stone is at rest, the stone which ought to have been played shall be put in its place, to the satisfaction of the opposing skip.

16. The sweeping shall be under the direction and control of the skips. The player’s party may sweep the ice from the hog score next the player to the tee, and any stone set in motion by a played stone may be swept by the party to which it belongs. When snow is falling or drifting, the player’s party may sweep the ice from tee to tee.... Both skips have equal rights to clean and sweep the ice behind the tee at any time, except when a player is being directed by his skip....

Note.—The all-important question of sweeping is dealt with later. The principle at the base of the rule is that a player’s side may encourage (or not) his stone to proceed, but the other side may not interfere with it in any way at all. In accordance with this principle is the direction that says that if a stone during its course moves a stone belonging to the other side, that stone may be swept or left alone at the option of the other side.

17. (a) If in sweeping or otherwise a running stone is marred by any of the party to which it belongs, it may, in the option of the opposing skip, be put off the ice; but if by any of the adverse party, it may be placed where the skip of the party to which it belongs shall direct....

(b) Should any played stone be displaced before the head is reckoned, it shall be placed as nearly as possible where it lay....

18. No measuring of shots shall be allowed previous to the termination of the head.

19. The skip shall have the exclusive regulation and direction of the game for his rink, and may play last stone or any part of the game he pleases.... When his turn to play comes, he shall select one of the players to act as skip in his place.
