P. T. Barnum,
The Humbugs of the World — Introduction
(1866)
“ There is not the least danger of a dearth of materials,I once travelled through the Southern States in company with a magician. The first day in each town, he astonished his auditors with his deceptions. He then announced that on the following day he would show how each trick was performed, and how every man might thus become his own magician. ”
