16. The dealer may leave the trump card on the pack until it is got rid of in the course of play. If the trump card has been taken up or played, any player may ask, and must be informed by the dealer, what the trump suit is; but any player naming the trump card may be called upon by an adversary to play his highest or lowest trump.
17. If the dealer takes up, or is ordered up, he must discard a card from his own hand, placing it under the remainder of the pack. Having quitted such discard, it cannot be taken back. If the dealer has not discarded until he has played to the first trick, he and his partner cannot score any points for that hand.
18. If the eldest hand leads before the dealer has quitted his discard, the dealer may amend his discard, but the eldest hand cannot take back the card led.
19. If the dealer takes up the trump to play alone, he must pass his discard across the table to his partner. If he fails to do so, the adversaries may insist that his partner play with him, preventing the lone hand.
20. MAKING THE TRUMP. If the dealer does not take up the trump, he must place it under the remainder of the pack, face upward, so that it can be distinctly seen. Each player in turn, beginning on the dealer’s left, then has the privilege of naming a new trump suit.
21. If any player names the suit already turned down, he loses his right to name a suit; and if he corrects himself, and names another, neither he nor his partner is allowed to make that suit the trump. If a player names a new trump suit out of his proper turn, both he and his partner are forbidden to make that suit the trump.
22. If no one will name a new trump, the deal is void, and passes to the next player on the dealer’s left.
23. IRREGULARITIES IN THE HANDS. If any player is found not to have his correct number of cards, it is a misdeal; but if he has played to the first trick the deal stands good, and he cannot score anything that hand.
24. EXPOSED CARDS. The following are exposed cards, and must be left face up on the table, and are liable to be called by the adversaries:
