DEMONSTRATION XIII. Have the hats of a number of men in the audience placed on a table or other place, and then returning to the room, blindfolded of course, you pick up the hats, one by one, and place them upon the heads of their proper owners, who are seated in different parts of the room. This is a simple feat although very effective. It is, of course, merely a variation of the feat of "finding the person." There is one point, however, that must be remembered in this feat, and that is that the Transmitter should know just whose hat is held in your hand--just who the owner of that particular hat is and where he is sitting or standing. Otherwise he cannot send you the mental impulses which will enable you to find the owner. It will be well for the Transmitter to hold the hat so that it can be seen by the audience, requesting the owner to rise in his seat so as to indicate his whereabouts--your back being turned to the audience while this is being done in order to avoid suspicion of your "peeping," etc. THE LADY AND THE RING. DEMONSTRATION XIV. This feat is performed by having a lady in the audience loan the Transmitter her ring. When you return to the room, you find the lady and replace the ring upon the finger from which she took it. The Transmitter must remember the lady, and the particular finger, of course--the rest is simply a combination of the "finding the person" and "finding the spot" feats. It is very effective, if neatly performed. GENERAL ADVICE. I. We have given you a great variety of Demonstrations or Feats, but you must not attempt to produce all of them at an evening's entertainment. It will take some time to perform a few of them effectively, and impressively, and you should avoid any attempt to hurry through the feats. Nor should you spoil your good impression by cheapening the demonstrations in the direction of performing too many at one sitting. II. Neither should you tire or fatigue yourself by too many feats. When your mind or body are tired, you do yourself an injury to perform these demonstrations, and besides, you cannot obtain the best results while fatigued. You should rest a little while after each feat, before attempting another one. III. When the entertainment, or exercises are over, you should take a few strong deep breaths, swing your arm around a little to promote the circulation, and relieve the nervous tension. You may feel a little "dazed" at first after performing a few feats, but will soon learn to throw off the passive condition, and engage in the laughing conversation that will follow the entertainment. Do not take yourself too seriously and remember that laughter and a little boyish or girlish spirits is a wonderful tonic.
