THE TRUMP CARD.
52. The dealer, when it is his turn to play to the first trick, should take the trump card into his hand; if left on the table after the first trick be turned and quitted, it is liable to be called; his partner may at any time remind him of the liability.
53. After the dealer has taken the trump card into his hand, it cannot be asked for; a player naming it at any time during the play of that hand is liable to have his highest or lowest trump called.
54. If the dealer take the trump card into his hand before it is his turn to play, he may be desired to lay it on the table; should he show a wrong card, this card may be called, as also a second, a third, etc., until the trump card be produced.
55. If the dealer declare himself unable to recollect the trump card, his highest or lowest trump may be called at any time during that hand, and unless it cause him to revoke, must be played; the call may be repeated, but not changed, i.e., from highest to lowest, or vice versa, until such card is played.
CARDS LIABLE TO BE CALLED.
56. All exposed cards are liable to be called, and must be left on the table; but a card is not an exposed card when dropped on the floor, or elsewhere below the table. The following are exposed cards:—
I. Two or more cards played at once.
II. Any card dropped with its face upward, or in any way exposed on or above the table, even though snatched up so quickly that no one can name it.
57. If any one play to an imperfect trick the best card on the table, or lead one which is a winning card as against his adversaries, and then lead again, or play several such winning cards, one after the other, without waiting for his partner to play, the latter may be called on to win, if he can, the first or any other of those tricks, and the other cards thus improperly played are exposed cards.
