Then follows the process of calling, which has been already described.

We have gone upon the principle of calling the stake a penny per trick, but of course it can be sixpence, or any other amount. It may, however, be observed that "Penny Purchase" is really as expensive as threepenny ordinary Nap.

There are some few points to be remembered.

A declaration once made stands, and cannot be recalled.

A player at Purchase Nap, having once bought fresh cards or refused to buy, cannot subsequently amend his decision.

Unless there is an agreement to the contrary, the dealer must, in default of any higher call, make one trick, or pay 1d. each to the other players.

Any one who has trumped a suit, or renounced upon a suit before all the five tricks have been played out, and so made or defeated a declaration, must immediately show his remaining cards to prove that he has not revoked. So stringent is this rule, that if he should refuse to show them, he is held to have revoked, and a revoke entails the following penalties:—

On the revoke being discovered, the cards must be taken up and replayed properly—that is to say, players must follow suit, if they can; and always remember that a revoke is just as much a revoke if you throw away a card of another suit, holding a card of the suit led, as if you trumped under the same circumstances.

The hand having been replayed, the offender pays the stakes for himself and every one of the other players to the caller, if the call succeeds. If the call fails, he pays the stakes to every other player, except the caller.
