DEMONSTRATION VI. Like the last feat, this is a complex and difficult one, but one that always arouses enthusiasm in an audience when well performed. It will repay you for the private practice that you will have to employ upon it, before you produce it in public. The feat consists of the audience selecting a book from a pile, or a book-shelf, or book-case, etc.--then a given page is chosen--then a line of printed matter on that page--and then a _word_ in that line. It is well to have the Transmitter draw a pencil circle around the chosen word, so that he may be sure to remember it later. The book is then replaced on the shelf. Then returning to the room, you first find the book, by the methods already given in previous feats; then laying it flat on the table you should begin to slowly and deliberately pick each leaf up separately. This part of the feat is almost identical with the last one, in which you picked up the cards from the pack. When you get the proper impression, you should announce that you have found the leaf. If satisfied that you are right, ascertain upon which side of the leaf, the chosen page is. This can be done by pressing the leaf to the right, or left, in succession, until you get the right impression as to which way to press it down. Then, having thus found the page, pass your finger slowly down and back over the page several times, until you get the impression of a _centre_. This centre will be the chosen line. Then by passing the finger slowly along the line, you will discover the Word when you reach it. This is a "ticklish" feat, but it may be mastered by practice--in fact some people have found it almost as simple as some of the easier feats, while others require careful practice with it. Do not be discouraged if you do not succeed at first trial, even in public, but try again, and after a bit you will seem to "get the knack" all at once, and thereafter will have but little trouble in making the demonstration. If you find that you do not meet with the desired degree of success in this feat, try it by the "Simpler Method" given at the last of this part of the book. But do not give it up without the proper practice. If you have carefully performed the previous feats, you should have so developed yourself by this time that you should have no special difficulty in this feat. BLACKBOARD DEMONSTRATIONS. The following feats may be performed either upon a large blackboard hanging from the wall, or upon a large sheet of card-board, or stiff paper, spread upon the table. If the blackboard is used, you should stand before it, the Transmitter standing in the usual position. If the table is used, you should stand before it, the Transmitter in his usual place.
