18. Any one quitting a table prior to the conclusion of a rubber may, with the consent of the other three players, appoint a substitute in his absence during that rubber.
19. Should a player leave a full table after he has played but one of the two consecutive rubbers to which he is entitled, the candidate next in order for entrance to the table takes his place, but must go out at the end of one rubber, as his predecessor would have done.
20. A player cutting into one table while belonging to another, loses his right of re-entry into the latter, and takes his chance of cutting in as if he were a fresh candidate.
21. If any one break up a table, the remaining players have the prior right to him of entry into any other; and should there not be vacancies at such other table for all those candidates, they settle their precedence by cutting.
SHUFFLING.
22. The pack must neither be shuffled below the table, nor so that the face of any card can be seen.
23. The pack must not be shuffled during the play of a hand.
24. Each player has a right to shuffle once only, except as provided by Law 27, prior to a deal, after a false cut, or when a new deal has occurred.
25. The dealer's partner must collect the cards for the ensuing deal, and he has the first right to shuffle that pack.
26. Each player, after shuffling, must place the cards, properly collected and face downwards, to the left of the player about to deal.
