When the dealer's card turns up, he may take the stake and pass the bank; or he may allow the stake to remain, whereat of course it becomes doubled if met. He can continue thus as long as the cards turn up in his favour -- having the option at any moment of giving up the bank and retiring for that time. If he does that, the player to whom he passes the bank has the option of continuing it at the same amount at which it was left. The pool may be made up by contributions of all the players in certain proportions. The terms used respecting the standing of the stake are, 'I'll see' (à moi le tout) and Je tiens. When jumelle (twins), or the turning up of similar cards on both sides, occurs, then the dealer takes half the stake.
Sometimes there is a run of several consecutive winnings; but on one occasion, on board one of the Cunard steamers, a banker at the game turned up in his own favour I think no less than eighteen times. The original stake was only six pence; but had each stake been met as won, the final doubling would have amounted to the immense sum of L3,236 16s.! This will appear by the following scheme: --

In fair play, as this is represented to have been, such a long sequence of matches must be considered very remarkable, although six or seven is not unfrequent.
Unfortunately, however, there is a very easy means by which card sharpers manage the thing to perfection. They prepare beforehand a series of a dozen cards arranged as follows: --
1st Queen 6th Nine
2nd Queen 7th Nine
3rd Ten 8th Ace
4th Seven 9th Eight
5th Ten 10th Ace
Series thus arranged are placed in side pockets outside the waistcoat, just under the left breast. When the sharper becomes banker he leans negligently over the table, and in this position his fingers are as close as possible to the prepared cards, termed portees. At the proper moment he seizes the cards and places them on the pack. The trick is rendered very easy by the fact that the card-sharper has his coat buttoned at the top, so that the lower part of it lies open and permits the introduction of the hand, which is completely masked.
Some sharpers are skilful enough to take up some of the matches already dealt, which they place in their costieres, or side-pockets above described, in readiness for their next operation; others keep them skillfully hidden in their hand, to lay them, at the convenient moment, upon the pack of cards. By this means, the pack is not augmented [Robert Houdin, Les Tricheries des Grecs dévoilées].
