Ball a, a is introduced as an imaginary one from which the player may make the mental calculation of the angles necessary to secure the carom, as shown before in Plate VII.
After finding the angles place the ball 1 as in diagram, strike cue-ball (2) ½ right, ¼ below, object-ball ½ right; stroke, “ordinary.” Cue-ball cushions at a, b, c, d, and e, caroming on ball 3.
Should a ball be located at either of the points indicated as those where the cue-ball contacts with the cushion, of course a carom would be effected there as well.
PLATE XI.
THE CUSHION KISS.
Illustrating the four kiss strokes possible by making stroke on different points of the cue-ball and the object-ball ⅞ right.
To kiss to cushion at c.—Where a ball may rest: cue-ball ½ above, object-ball ⅞ right; stroke, “ordinary.” The cue-ball will describe the curve line from ball 1 to c. Should player desire to reach any point between c and e the ball 1 should be hit from ⅞ to ¾ right. Judgment must be exercised as to the precise fractional part and also the strength of stroke.
To kiss to b.—Cue-ball ⅛ below centre, object-ball ⅞ right; stroke, “ordinary.”
To kiss to d, the natural angle of reflection, cue-ball ½ below, object-ball ⅞ right; stroke, “ordinary.”
