joining the centres of the balls.

18. _A ball can acquire the right to re-roquet--that is, to roquet the
same ball again during the same tour--only by making a step on the
round._

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 croque
