On Leading
1. The player who wins the choice of balls and lead must either roll his ball down towards the lower cushion, as an object for his adversary to play at, or else compel his adversary to lead off as above described. 2. In leading, the player's ball must be played from within the string-line, and struck with sufficient strength to carry it beyond the deep-red ball on its appropriate spot at the foot of the table. But it must not be played with such strength as to repass, after coming in contact with the lower cushion, the deep-red ball. Nor yet must it touch either red ball, nor lodge on the cushion, nor fall into a pocket, nor jump off the table. In any of the cases mentioned in this section, or in case the cue-ball is not struck with sufficient strength to pass beyond the deep-red, it shall be optional with the adversary (Player No. 2) to make No. 1 spot his ball on the pool spot nearest the lower cushion, or lead again: or he may take the lead himself. 3. No count or forfeiture can be made or incurred until two strokes have been played. 4. Once the lead is made, the game is considered as commenced, and neither player can withdraw except under circumstances specified on page 803.
