You will never have to worry about forcing a card again. Forces using regular cards, prepared cards, numbers, and a section on miscellaneous forces are all fully explained.
 
From Theodore I want to say right at the start that I am not claiming any originality for the contents of this manuscript. In a number of instances I think I have added some forces and methods that are my own, but it would be hard to prove because of the sameness in basic principles. In my professional work I found that many times I had need of a good force and on the spur of the moment it was hard if not impossible for me to think of the most suitable method for the conditions under which I was working. I know that this is a situation in which every worker has found himself, and because of that I know just how useful this compilation will be.It was over a year ago when Arthur Lloyd, the Human Card Index, whose name and act (the only one of its kind) has graced practically every vaudeville theatre in the world, spoke to me about the usefulness of a complete compilation on the subject of forcing. I immediately agreed, and for one year have picked up and filed every possible method that I could locate. I know well enough that the collection is not complete. No collection of anything pertaining to Magic is complete insofar as methods go. But I do know that this is the first time such a collection has been offered and therefore I have done my best to make it as representative as possible.I have found it next to impossible to actually classify every method because it would mean cross indexing practically everything I have written.In separating them under four headings I have placed Cards in general, Prepared decks for forcing, Numbers and Miscellaneous by themselves which is something if not everything.Practically all of the number methods can be used in some manner with book tests. Name and word methods come under the same heading and combine in many cases with those used for cards. Then there are novel methods which use apparatus well known to magicians and common objects to be found most everywhere.Under one of the headings you will find the particular method you need at the moment. And if you have need of a force that can't be solved by this compilation, I certainly will go on record as saying that as far as I'm concerned, it doesn't exist.
