The following is the method of presenting the above trick, with appropriate "patter":
"For the purpose of my next experiment I shall make use of this square-looking piece of paper, in which you can see there is nothing concealed, not even a trap-door. Well, if there was anything concealed from your view, you would be sure to see it." Laying the paper down and taking up the handkerchiefs, you continue, "In addition to the paper, I propose to make use of these three pieces of silk, or silk in pieces, commonly known as art white squares. I am afraid, however, some people would prefer to call them subdued white; possibly dirty white, if it were not for the liberty of the thing, but I know they call them art white in the stores, because I suppose they find they sell better."
Laying the handkerchiefs down, you take up the paper with the tube behind it, and, prior to forming the cylinder, remark:—"This experiment was suggested to me while in England traveling on the underground railway. I always travel by that line when possible, being fond of scenery. One day I had occasion to take a return single from Portland Road to King's Cross; and while passing through those tunnels I noticed that my linen changed color considerably, which suggested to me this illustration. With the piece of paper I will form a kind of tube or tunnel to represent for the time being one of those cavities on the underground railway."
Make the tube and continue:—"There it is, as free from deception as I am. I will now take the handkerchiefs" (take up the handkerchiefs from the table) "and pass them through the cylinder" (drop the colored handkerchiefs into the white ones and show the tube empty), "first, however, showing you that it is perfectly empty. Then, having satisfied you that there are no trains on the line, I will pass the handkerchiefs through the tunnel."
As the colored handkerchiefs appear at the opposite end of the tube, remark:—"I may say that I have been getting my living for some considerable time by conjuring. You will now notice that I am beginning to dye by it."
Mechanical "Pull" for Vanishing a Handkerchief.—The construction of this contrivance is very simple, and it is absolutely instantaneous in its action, the quickest eye being unable, even at close quarters, to detect the flight of the handkerchief.
It consists of two straps, one for each arm, which are buckled on just above the elbows. One of the straps carries what is known to mechanics as a "lazy" pulley, working freely in all directions, and provided with a shield, so that the cord cannot possibly leave the wheel; and the other carries a metal "D" loop. A cord is tied to the "D" loop, passed over the back, round the pulley on the left arm, back again and down the right sleeve; the end of the cord being furnished with a loop to receive a handkerchief. The apparatus must be attached to the arms underneath the shirt, and when in such a position that the arms may be moved about freely, the loop should be in the centre of the back, as shown in Fig. 17.

To enable the artist to obtain possession of this loop, a black thread is passed through it, doubled and carried down the right sleeve, the two ends hanging out of the cuff so as to be readily found by the fingers. Having found the thread, the performer pulls it down until the loop appears, which is forthwith passed round the thumb, the thread being broken and allowed to fall on the floor. The act of pulling the cord to secure the loop will pull the elbows close to the sides, where they must be kept until the handkerchief is to disappear.
