After you have mastered the last mentioned exercise, have the
Transmitter select a small object, such as a watch-key, match-safe,
etc., and secrete it in some part of the room, you remaining out of the
room until the article is selected and hidden. Proceed as before, until
you find the secreted object. Your Transmitter should endeavor to give
you a great variety in this exercise, in order to properly train you for
the public demonstrations before companies, etc. Have him place a key in
a book, under a rug, back of a picture, and in similar difficult places.
Let him exercise his ingenuity in finding strange places in which to
hide the object. In the experiments in finding the hidden objects he
must train himself to give you the mental messages "up"; "down"; "to the
right"; "to the left," etc., just as he did his old message or impulse
"this way." And you must train yourself to receive them. This training
will be of the greatest possible benefit to you when you are called upon
later to find objects hidden in people's pockets, etc.
