This lot being taken up and the hand being in the position shown in the figure, snatch up in like manner the other lot, and, by a movement of the palm of the hand and the tips of the fingers, pass the second lot under the first. The deception of the trick depends upon its dexterity, and this can only be acquired by practice. But really it may be dispensed with; for it is a curious fact that, in every case when the cards are cut, you may actually replace them just as they were without being observed by the spectators--for the simple reason that the ruse is not suspected, especially if their attention is otherwise engaged with your pointed observations. The 'gift of the gab' is in this case, as in many others, a very great resource. A striking remark or bon mot will easily mystify the spectators, and attract their attention from what you are DOING. Hence all prestidigitators are always well stocked with anecdotes and funny observations; indeed, they talk incessantly: they speak well, too, and they take care to time the word accurately with the moment when their fingers act most energetically. III. To slip a card.--To slip a card is to pretend to take the bottom card of the pack, and in reality to take the card which precedes it. To perform this feat without detection is a very simple affair, but it requires practice. The pack of cards being held in the right hand, advance the left hand--palm upwards--just as if you were seizing the last card with the middle finger; but, having slightly moistened this finger with the lips, push back this card, and make it slip under the palm of the right hand, whilst you seize the preceding card with the thumb and forefinger. In this manner you may successively draw out several cards besides the last, and only draw the last as the sixth, seventh, &c., which will serve to effect several interesting tricks to be explained in the sequel. IV. To file the card.--To file the card is, when a card has been taken from the pack to pretend to place it about the middle of the pack, whilst, in reality, you place it at the bottom. The pack must be held in the left hand, between the thumb and forefinger, so that the three other fingers be free. One of the middle cards should project a little. Then take the card to be filed between the forefinger and the middle finger of the right hand; advance the right hand from the left, and whilst the three disengaged fingers of the left hand seize and place the card under the pack, the thumb and forefinger of the right seize the projecting card before mentioned, so that it seems to be that card which you have slipped into the middle of the pack. These movements are very easy, and, when rapidly performed, the illusion is complete. TRICKS. 1. To tell a card thought of by a party after three deals. Take twenty-one cards of a pack, and deal them out one by one in three lots, requesting the party to think of a card, and remember in which lot it is.
