double, but he may redouble a declaration of his partner
which has been doubled by an adversary.

55. The act of doubling, or redoubling, reopens the bidding. When a
declaration has been doubled or redoubled, any player, including the
declarer or his partner, can in his proper turn make a further
declaration of higher value.

56. When a player whose declaration has been doubled wins the declared
number of tricks, he scores a bonus of fifty points in the honor
column, and a further fifty points for each additional trick. If he or
his partner has redoubled, the bonus is doubled.

57. If a player double out of turn, either adversary may demand a new
deal.

58. When the final declaration has been made the play shall begin, and
the player on the left of the declarer shall lead.

DUMMY

59. As soon as the player to the left of the declarer has led, the
declarer's partner shall place his cards face upward on the table, and
the duty of playing the cards from that hand shall devolve upon the
declarer.

60. Before placing his cards upon the table the declarer's partner has

_b_ To call the declarer's attention to the fact that too many or

_c_ To correct the claim of either adversary to a penalty to which
the latter is not entitled;

_d_ To call attention to the fact that a trick has been erroneously
taken by either side;

_e_ To participate in the discussion of any disputed question of
fact after it has arisen between the declarer and either adversary;

_f_ To correct an erroneous score.

61. Should the declarer's partner call attention to any other incident
of the play in consequence of which any penalty might have been
exacted, the declarer is precluded from exacting such penalty.

62. If the declarer's partner, by touching a card or otherwise, suggest
the play of a card from dummy, either adversary may call upon the
declarer to play or not play the card suggested.

63. Dummy is not liable to the penalty for a revoke; if he revoke and
the error be not discovered until the trick is turned and quitted,
whether by the rightful winners or not, the trick must stand.

64. A card from the declarer's own hand is not played until actu
