Card Tricks Revealed - THE CARD FOUND UNDER THE HAT

Have a needle stuck just inside your sleeve. Hand the cards, &c. just as in the preceding trick, and tell the taker to put the card on the top.
Take out the needle, and prick a hole nearly through the top left-hand corner.
Replace the needle, shuffle the cards, or let any one shuffle them.
Place the pack on the table, cover them with a hat, and the marked card will be known by a little raised knob on the right-hand top corner.
Draw out card by card, saying whether it is that card or not, until you come to the marked one, which you throw on the table carelessly, and when you are about taking out another card, stop suddenly, and pretend to find, by some magic process, that it is the chosen card.
