The welcome accorded to Design for Magic has given me the necessary encouragement to present this present volume. I hope that among the score of original ideas and effects, there may be something of use for every type of magician. Some of the effects rely in part upon mechanism for their accomplishment. My views on mechanism in Magic agree with those well expressed by John Mulholland, who a few years ago wrote the following in The Sphinx.
"When mechanics are used in Magic, they must be so designed and constructed that they are infallible. When a trick depends on mechanism and the mechanism fails to operate, there is no trick, and, to the audience there is no magician."
