equipment and materials for the work include the drawing board, the drawing paper and the chalk (or lecture crayons).

The Drawing Board.

Probably your school has a reversible blackboard mounted on an easel, like that shown in Fig. 1. If so, you will find it amply sufficient for your use. The two or three little holes made by the thumb tacks, to attach your drawing paper to the board, at the top, will not injure it in the least. If you haven't such a board, it would be well to procure one, as it can be used for many purposes. The writer has often used a board of this kind in giving chalk talks. The publishers of this book will be glad to give full information as to size and price of such a board.

Another convenient and cheap equipment is an ordinary square board, Fig. 2. If you take six boards, each 45 inches long, 7 inches wide and 1/2 inch thick, and attach them to two cleats at the back, you will have a good, serviceable drawing board which can be hung against the wall with screw hooks and screw eyes; or, it can be set on an easel or other convenient holder. It is only necessary that the board be smooth and the wood be well-seasoned soft pine or bass wood to keep it from warping. If screws are used to fasten the boards to the cleats, screw them through from the back, leaving the front perfectly smooth. Be sure that the screws aren't too long. It would be well to stain the board brown or some other dark color.

A combination drawing board and easel is shown in Fig. 3, a back view of which is given. Take six boards of well-seasoned soft pine, 45 inches long, 8 inches wide and 1/2 inch thick. For the rear legs, use two pieces 5 feet and 8 inches long, 2 inches wide and 1/2 inch thick. A wire should be attached to each rear leg to avoid spreading. Fig. 4 shows this board and easel in use.

The Drawing Paper.

The most inexpensive paper for chalk talk work is the kind on which newspapers are printed. It may be purchased from printing houses, paper dealers or newspaper offices. A cheap quality of book-paper is also good, and may be bought from printing houses and paper dealers. Ordinary light-colored, light-weight manila paper, such as is used for wrapping, is very satisfactory; it may be procured from paper dealers, or, if you want but a small quantity, probably any merchant would be glad to supply you. The lines which you intend to place on it may be worth infinitely more than the goods he plans to wrap in it.

The Chalk.

The writer is accustomed to using chalk made by the American Crayon Company, which can be had at any time from the publishers of this book, and, doubtless, from other publishers. Ask for "lecture crayons." A complete price list, together with samples of colors, will be furnished on request. For general work it is well to have on hand a half dozen sticks of black and a stick each of green, brown, red, yellow, orange and blue. The lecture crayons come in two sizes, one measuring one inch square and three inches long; the other is one-half inch square and three inches in length. If you choose the larger size, the sticks can, when advisable, be cut to the smaller size.

PREPARING TO GIVE THE TALK

The instructions here given are for the beginner. Others will follow their accustomed methods. In our introduction we make the claim that any earnest Christian worker, who is capable of addressing an audience or a Sunday school class can, by the aid of this book, give a helpful chalk talk.

Your response may be, "But, I can't draw." Listen! The following instructions will teach you how to do the work without a technical or practical knowledge of drawing. Let us take up the matter step by step. When you understand the process, it will be "as easy as falling off a log," and it won't jolt you half as much.

The Method Explained.

THE FIRST STEP—Before the time comes to give your talk, attach half a dozen sheets of your drawing paper to your drawing board, making a smooth drawing surface. It is well to use thumb tacks for this purpose. Open the book to page 19, for we will prepare to give the chalk talk entitled "The Two Faces." The upper picture. Fig. 7, shows the picture partly finished; the lower picture, Fig. 8, shows how the picture will look when completed. You will note that the lower picture is cut up into squares measuring one-fourth of an inch each way.

THE SECOND STEP—By the use of a yardstick and lead pencil, draw pencil lines on the large sheets of drawing paper, so as to separate the drawing paper into the same number of squares as there are on the picture in the book. Your paper is much larger than the page of the book; therefore the squares on your drawing paper must be made much larger than the squares in the book. It is easy to calculate the size of the squares you should draw on the paper. Measure the width of the paper in inches and divide by sixteen (the number of squares across the picture in the book), and this will give you the figure representing the size of the squares you are to draw on the paper. If your drawing paper is thirty-two inches wide, your squares will measure two inches each way.

THE THIRD STEP—Select one of the squares in Fig. 8 as a starting point, and then find the corresponding square on your drawing paper. Having done this, draw a pencil line on your drawing paper, which will cross your enlarged squares in just the same places that the line crosses the small squares in the book. Continue the process until both faces have been outlined on your paper in the enlarged form. Then, with a piece of soft rubber, erase all of the straight pencil lines which form the squares, and the remaining outlines of the two faces will stand out clear and distinct. Already you will have found that you are more of an artist than you thought
