"Having now," says he, "bestowed some waste money among you, I will set you to cards; by which kind of witchcraft a great number of people have juggled away not only their money, but also their lands, their health, their time, and their honesty. I dare not (as I could) show the lewd juggling that cheaters practice, lest it minister some offence to the well-disposed, to the simple hurt and losses, and to the wicked occasion of evil doing. But I would wish all gamesters to beware, not only with what cards and dice they play, but especially with whom, and where they exercise gaming. And to let dice pass, (as whereby a man may be inevitably cousened,) one that is skilful to make and use Bumcards may undo a hundred wealthy men, that are not given to gaming; but if he have a confederate present, either of the players or standers-by, the mischief cannot be avoided. If you play among strangers, beware of him that seems simple or drunken; for under their habit the most special couseners are presented; and while you think by their simplicity and imperfections to beguile them, (and thereof, perchance, are persuaded by their confederates, your very friends as you think,) you yourself will be most of all over-taken. Beware also of the betters by and lookers on, and namely of them that bet on your side; for whilst they look on your game without suspicion, they discover it by signs to your adversaries, with whom they bet and yet are their confederates."
Among the tricks with cards which he notices, are the following: "How to deliver out four Aces and to convert them into four Knaves. How to tell one what card he seeth in the bottom, when the same card is shuffled into the stock. To tell one, without confederacy, what card he thinketh. How to tell what card any man thinketh, how to convey the same into a nut-shell, cherry-stone, &c., and the same again into one's pocket. How to make one draw the same, or any card you list, and all under one devise." The two verses which he quotes in the margin should be inscribed as a motto on the dial-plate of every gamester's watch. "Of dice play, and the like unthrifty games, mark these two old verses, and remember them:
Ludens taxillis, bene respice quid sit in illis: Mors tua, sors tua, res tua, spes tua, pendet in illis."
