Before taking you on with the work before an audience, we must urge upon you to prepare yourself thoroughly by means of the above mentioned exercises. The great tendency among students is to hurry through to the public work, and skipping the exercises as much as possible. This is all wrong. You will never be a thoroughly good demonstrator of anything in life, until you master the rudiments, and by practice familiarize yourself thoroughly with the details of the work. And Mind Reading is no exception. It is true that after a few exercises you may be able to give a fair demonstration before an audience, but you will never get further than "fair" without careful practice. And therefore we urge you to have patience and perseverance, and to stick to the exercise until you become a Master of Mind Reading, when you need fear no audience whatsoever, and will be able to give a demonstration that will be a great credit to both yourself and to us, your instructors. And, now for your work before an audience, remembering, always that the feats and experiments that we shall mention, should be practiced by you privately, with the aid of a friendly Transmitter, before you reproduce them in public. In the case of feats, in which the audience is a party to the experiment, such as the finding of a scarf-pin on a member of the audience, you may practice with a dummy audience, that is with an imaginary audience consisting of chairs, etc., until you familiarize yourself with the details of the feat. LESSON V. SIMPLE DEMONSTRATIONS. In beginning a public demonstration, it will be well for you to give a short preliminary talk to the audience, somewhat along the following lines: OPENING TALK.
