The Mysterious Problem.

The following combination of two old principles makes a pleasing conjuring experiment for parlour pre-

sentation. It is very simple in operation, requires no skill to speak of, yet with appropriate " patter " it makes an astonishing effect. The method found most satisfactory is as follows : The performer displays a large sheet of white paper, calling attention to the fact that it contains no writing or marking of any kind. This is suspended from a frame or rested against an easel in full view of the spectators. Then the entertainer addresses the audience and requests them to think of a number. This being done, they are asked to multiply the number thought of by 2. The next step in the process is to add 6, and t® divide the result thus obtained by two. Next, direct' them to ■ subtract the number originally thought of and to add 4 to the final result. The conjuror then applies a match to the paper, which is seen to burn up with the exception of a strip that resembles the figure 7 very distinctly. Seven proves to be the answer to everybody's problem regardless of the fact that each person thought of a different number to begin with. To obtain the effect with the paper the reader must add a few drops of nitric acid to a sufficient quantity of asbestos paint, and with a brush outline the figure on tho paper and allow it to dry. This, of course, must bQ done prior to giving the exhibition. Seven will always be the answer if the above formula is employed. A little talk I'elative to the peculiar properties of the figure seven would add to the anvusoment of the trick. Try it.
