Fig. 2.—Dividing the Object Ball.
[Fig. 2], No. 1, shows the object ball struck full, [fig. 2], No. 2, the three-quarter ball, and so on. The half ball is the most important in practice, as by it the natural angle is made, an angle that is of the greatest importance at billiards, though each have their particular uses, which the young player should endeavour to understand. He will find that the balls diverge at different angles, more or less acute, according as the object ball is struck “full” or “fine;” the fine ball being precisely the reverse of the three-quarter ball.
