This, then, is the reason that the chalk talk method of teaching is so lastingly impressive. People forget everything else while watching a speaker draw a picture. And if they do that, they can never completely forget the words of the speaker or the picture he draws. A baby that doesn't know one letter from another can understand some pictures as well as _you_ can. Try him once and see. And if he lives to be a hundred years of age, he will receive more lasting impressions from pictures than from what he reads. Your audience, therefore, may be depended upon to be "right with you" from the beginning. ~~The Two-Scene Method.~~ Added to this feature of securing strict attention, we find in this book another help in the same direction: Every talk is given in two "scenes" or steps. The speaker draws part of the picture, while he speaks, and then, at a little later period, adds the lines to complete the drawing and bring the scene to a climax. In each talk, the upper picture is the first scene, and the lower picture is the second scene, or completed drawing. ~~Chalk Work on Paper.~~ The book is planned to encourage the use of sheets of book- or news-paper instead of the blackboard. Paper is used by all leading workers with chalk. To discard the blackboard is to take a forward step. However, if you are "wedded" to the use of the blackboard and can handle it effectively, you will find all but a small number of these illustrations adapted to your method. ~~Materials Are Cheap.~~ Probably your school or church is already supplied with the necessary apparatus to do all the work as planned in this book. However, for any who may need to provide for himself a drawing board and easel, instructions for making them are here given. It is only necessary, then, to procure drawing paper and chalk. These are cheap in price and easy to get. You are urged, therefore, to proceed with the use of drawing paper as here instructed, and to lay aside the blackboard for the more advanced method. ~~Important to Beginners.~~ Each drawing in the book, as already stated, is given in two "scenes," in order to show you how your drawing will look _when it is partly finished_ (first scene), and how it will look _when it is completed_ (second scene).
