Benjamin Garno, Modern Billiards
“ A player, when instructed to deliver a 1⁄8 cue-ball, for instance, will disregard the direction and deliver a 1⁄4 or even a 1⁄2 ball, apparently unconscious or careless of the value of the change. When it is understood that a cue-ball may be made to carom upon a ball placed anywhere upon the bed of the table by the application of the proper degree of twist, then the player will recognize the necessity or advisability of so fixing the various degrees in his mind as to have them always ready for use. ”
