for his opponent.
The game is decided by a certain number of rounds, or by points, usually 21
or 31. In other matters the rules of bagatelle apply.

_The Cannon Game._--This is usually considered the best and most scientific
of bagatelle varieties. Tables without cups are sometimes used. As in
billiards three balls are required, the white, spot-white and black, the
last being spotted and the non-striker's ball placed midway between holes 1
and 9. The object of the game is to make cannons (caroms), balls played
into holes, at the same time counting the number of the holes, but if a
ball falls into a hole during a play in which no cannon is made the score
counts for the adversary. If the striker's ball is holed he plays from
baulk; if an object-ball, it is spotted as at the beginning of the game. A
cannon counts 2; missing the white object-ball scores 1 to the adversary;
missing the black, 5 to the adversary. If there are pockets, the striker
scores 2 for holing the white object-ball and 3 for holing the black, but a
cannon must be made by the same stroke; otherwise the score counts for the
adversary.

_The Irish Cannon Game._--The rules of the _cannon game_ apply, except that
in all cases pocketed balls count for the adversary.

_Mississippi._--This variation is played with a bridge pierced with 9 on
more arches, according to the size of the table, the arches being numbered
from 1 upwards. All nine balls are usually played, though the black is
sometimes omitted, each player having a round, the object being to send the
balls through the arches. This may not be done directly, but the balls must
strike a cushion first, the black, if used, counting double the arch made.
If a ball is played through an arch, without first striking a cushion, the
score goes to the adversary, but another ball, lying in front of the
bridge, may be sent through by the cue-ball if the latter has struck a
cushion. If a ball falls into a cup the striker scores the value of the cup
as well as of the arch.

_Trou Madame._--This is a game similar to _Mississippi_, with the
exceptions that the ball need not be played on to a cushion, and that, if a
ball falls into a cup, the opponent scores the value of the cup and not the
striker.

_Bell-Bagatelle_ is played on a board provided with cups, arches from which
bells hang, and stalls each marked with a number. The ball is played up the
side and rolls down the board, which is slightly inclined, through t
