A ball may hit another ball twice or more during the same tour, and between two consecutive bridges, or between the bridge and the turning stake, and move it, each time by concussion; but only one (not necessarily the first) contact is a valid roquet.
19. A roquet, but no hit which does not fulfil all the conditions of a roquet, constitutes a point, and entitles to continuance of tour.
20. A roquet, but no other hit, entitles to the privileges of croquet.
21. The croquet may be declined, and the tour continued from the spot to which the player's ball has rolled, or from the side of the roqueted ball.
The privilege of the croquet thus consists of two parts. First, the option between the final position of the playing ball and a new position in contact with the roqueted ball, and on any side of it. Second, the croquet proper. The second only, or both parts of this privilege may be declined; but this must be distinguished from "declining roquet" afterward mentioned.
Case.—A ball not a rover having roqueted another ball, is placed in contact with it, and, without using the foot, the player drives them both in any direction, as in roquet-croquet. Is this allowed? Yes. The croquet was declined and the stroke was a common blow; but the other ball, being merely moved by concussion, (since it was previously roqueted,) the tour cannot be continued unless a point was made at the same time.
22. If after a roquet the playing ball be taken up or moved from its place, it must continue its tour from the side of the roqueted ball.
Case.—A ball roquets another ball, driving the latter by concussion through the playing ball's proper bridge; remaining, however, in position to run the bridge. The player begins to move the ball, but on second thought concludes to run the bridge. Can he claim to have moved it by accident? No, even if it was not taken up from the ground; for it may be presumed that it was done with the intention to croquet. Whether he croquet or not he must take position by the side of the other, and has lost his opportunity to run the bridge. So, too, if he takes position under the arch of the bridge he is not in position to run it, for the space over which the ball is carried is no part of its course.
23. The croquet must be executed before continuance of tour.
Case.—A ball roquets another and on the same blow runs its bridge; the croquet is then executed. Does the run hold good. Yes, at the player's option. Case.—Under the same circumstances the playing ball is taken to the side of the roqueted ball. Can it re-roquet it on the ground that it has run a bridge since the roquet? No. The right to re-roquet must be acquired after croqueting or moving the playing ball. But the playing ball might have re-roqueted from its final position, declining the first croquet.
