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.
