Before anything else is done, each player has a right to reject some of his
cards, and take others in their place.
The elder hand begins. He has the privilege of discarding from his hand any
number of cards not exceeding five (he _must_ discard at least one), and
taking a corresponding number from the top of the stock. If he does not
take all his five, he may look at those he leaves, concealing them,
however, from the other player.
The dealer may then discard and replace in like manner, taking the cards
from the stock in the order in which he finds them. He is bound to discard
one, and he may, if he pleases, take all that remain, or any number of
them. He may look at any cards of his own portion of the stock he leaves
behind; but if he does, the elder hand may demand to see them too, after
playing his first card, or naming the suit he intends to play.
