|BLACK ART MATS 19 a quarter of an inch or so by means of a stiffening along its inner edge. By having the millboard foundation cut in half before it is covered, the mat may be made to fold like a chessboard for greater portability. FIG. 9 If some small article, say a coin or ring, is laid on mat just behind the mouth of the pocket, it may be made to disappear therein, being in fact swept into the pocket in the act of apparently picking it up. In the case of a coin, the pocket may by a slight alteration of procedure be used to effect a "change"; a substitute, palmed beforehand, being exhibited in place of the one professedly picked up from the mat. It is desirable when placing the mat upon the table for use to see that the mouth of the pocket is duly open and has not been, by any accident, pressed flat, and SO closed.
