The Vanishing Knots.
For this trick you must use a silk handkerchief. Twisting it rope-fashion, and grasping it by the middle with both hands, you request one of the spectators to tie the two ends together. He does so, but you tell him he has not tied them half tight enough, and you yourself pull them still tighter. A second and a third knot are made in the same way, the handkerchief being drawn tighter by yourself after each knot is made. Finally, taking the handkerchief, and covering the knots with the loose part, you hand it to someone to hold. Breathing on it, you request him to shake out the handkerchief, when all the knots are found to have disappeared.
When the performer apparently tightens the knot, he in reality only strains one end of the handkerchief, grasping it above and below the knot. This pulls that end of the handkerchief out of its twisted condition and into a straight line, round which the other end of the handkerchief remains twisted; in other words, converts the knot into a slip-knot. After each successive knot he still straightens this same end of the handkerchief. This end, being thus made straight, would naturally be left longer than the other, which is twisted round and round it. This tendency the performer counteracts by drawing it partially back through the slip-knot at each pretended tightening. When he finally covers over the knots, which he does with the left hand, he holds the straightened portion of the handkerchief, immediately behind the knots, between the first finger and thumb of the right hand, and therewith, in the act of covering over the knots, draws this straightened portion completely out of the slip-knot.
The Dancing Sailor.
The Dancing Sailor is a figure cut out of cardboard, eight or nine inches in height, and with its arms and legs cut out separately, and attached to the trunk with thread in such a manner as to hang perfectly free. The mode of exhibiting it is as follows:—The performer, taking a seat facing the company, with his legs slightly apart, places the figure on the ground between them. As might be expected, it falls flat and lifeless, but after a few mesmeric passes it is induced to stand upright, though without visible support, and, on a lively piece of music being played, dances to it, keeping time, and ceasing as soon as the music ceases.
The secret lies in the fact that, from leg to leg of the performer, at about the height of the figure from the ground, is fixed (generally by means of a couple of bent pins), a fine black silk thread, of eighteen or twenty inches in length. This allows him to move about without any hindrance. On each side of the head of the figure is a little slanting cut, tending in a perpendicular direction, and about half an inch in length. The divided portions of the cardboard are bent back a little, thus forming two “hooks,” so to speak, at the sides of the head. When the performer takes his seat, as before mentioned, the separation of his legs draws the silk comparatively taut, though, against a moderately dark background, it remains wholly invisible. When he first places the figure on the ground, he does so simply, and the figure naturally falls. He makes a few sham mesmeric passes over it, but still it falls. At the third and fourth attempt, however, he places it so that the little hooks already mentioned just catch the thread, and the figure is thus kept upright. When the music commences, the smallest motion, or pretence of keeping time with the feet is enough to start the sailor in a vigorous hornpipe.
CONUNDRUMS AND RIDDLES.
These are by no means of modern origin: the Sphinx puzzled the brains of some of the heroes of antiquity, and even Alexander the Great, as it is written, made several essays to untie the knot (a practical riddle) with which Gordius, the Phrygian king, who had been raised from the plow to the throne, tied up his implements of husbandry in the temple, in so intricate a manner, that universal monarchy was promised to the man who could undo it: after having been repeatedly baffled, he, at length, drew his sword, considering that he was entitled to the fulfillment of the promise, by cutting the Gordian knot.
