This book is offered, not as a manual of art, but as a practical guide to chalk talking, cartooning and plain illustrating. We feel that almost anyone who follows its clear rules and practices its easy, correct models will acquire the ability to deliver an entertaining chalk talk or to improve by illustrations the effect of a serious discourse. The reproduction or the adaptation of the pictures contained in the book will furnish abundant material for a vaudeville, Chautauqua, lyceum or other special entertainment; for they have been used successfully for just such purposes. - Introduction.
