BACKGAMMON. OR TRIC-TRAC.

Backgammon is played by two persons, each of whom is provided with fifteen men, two dice, and a dice-box. The men on each side are of different colours, black and white, and the players are distinguished by the colour of the men with which they play. The board is divided into two tables, inner and outer, and at the beginning of the game the men may be set up in either of the positions shown in the diagram.
