'Modern Magic' is a treatise in book form, detailing the apparatus, methods and tricks used by the magicians and conjurors. It was the first book in the English language to really explain how to perform magical feats. The treatise contains advice on the appearance, the dress and the staging of a magician. It then goes on to describe many tricks with playing cards, coins, watches, rings, handkerchiefs, dominoes, dice, cups, balls and hats, and concludes with a long chapter of miscellaneous tricks, including magic with strings, gloves, eggs, rice and some utility devices. The penultimate chapter describes large stage illusions, and the final chapter contains advice on routining a magic show, as well as more advice on staging.
