DEMONSTRATION III. Similar to the above is the feat known as the "Game of cards." Two players sit opposite each other at a table, having dealt themselves two hands of euchre. Have the Transmitter lead you behind the first player, and standing there have the player silently point out the card he wishes to lead, to the Transmitter. The Transmitter then should concentrate his mind on the card, and you will find it in the usual manner, and having found it will play it on the table. Then leading you around to the other player, the Transmitter repeats the process, and you find and play the card. Then back to the first play, and repeat. Then alternate between the players, in the same manner, until you have played out the game. This may be improved upon by the Transmitter thinking of which player has won the trick, when you will push the cards over to the winner, having discovered the direction in the usual manner. This feat is very effective indeed when properly performed. THE MAPPED-OUT TRIP. DEMONSTRATION IV. Have a map laid open on the table, and have the audience decide upon a trip between two points, either by rail or by water. Then returning to the room, stand as above described, and with your forefinger find the place from which the trip starts. Then move slowly along the selected course in the same manner in which the checker-game was played, passing along the chosen route until the end is reached. These feats are all really variations of the one principle. THE PACK OF CARDS.
