By the first method it will be seen that the card first shown is left, after the change, at the bottom of the pack. This result is not always desirable. When the cards have to be, as is sometimes the case, changed back into their former positions, the card must be left at the top at each change. In this instance, the ace of diamonds must be held between the thumb and first finger of the right hand; the ace of clubs being, as before, at the top of the pack, and slightly pushed off by means of the thumb. On the hands being brought momentarily together, the ace of clubs is seized between the first and middle fingers of the right hand, the ace of diamonds being left on the top of the pack. The thumb of the left hand is utilised in detaining the ace of diamonds, which, without its use, would probably fall on the floor. The first finger of the left hand must be kept well out of the way, or it will interfere with the smooth passage of the cards. Fig. 37 represents this change just as the hands are brought together. Noise is more likely to be made by this change than by the preceding one, so care must be taken to avoid it as much as possible. The "three card trick," so much in vogue amongst card-sharpers in wheedling money out of the pockets of greenhorns, becomes very amusing when worked by means of this change. The usual shifting about of the cards upon the table must be executed in the most childishly simple manner, which will not much matter, as you will take care to speedily change the card to be found, for one on the top of the pack. When the spectators have amused themselves for some time in endeavouring to find out a card which is not there at all, you will change it back again.
