I will now describe how the writing is obtained upon the interior of two slates sealed together, and all hands placed on them, and without the assistance of a confederate. The table is the same as previously described, that is, it contains the trap. The slates are two single ones hinged together and sealed around the edges in any manner the committee may see fit. One of the slates is a trick slate made in this fashion: The slate part itself is made to work on a pivot or hinge along one of its sides. (Fig. 9.) The side opposite to where both slates are hinged together, by touching a portion of the hinges that hold the two slates together, a catch concealed in the wooden framework is released, which allows the slate part itself to drop down on its own hinge or pivot. So when the slates are placed on the table they are put directly over the trap in the table, and with the hinges of the two slates toward the medium. The medium, as he places the slates over the trap in the table, pushes the hinge releasing the catch, which allows the underneath slate to drop as far as the table. Now, when the trap in the table is opened, the slate opens or drops far enough for the medium to write on that part, also on the slate above it. He closes both the slate and the table, and the slates, upon being unsealed, are found covered with writing. The only thing that remains to be explained is how the medium gets his hand free to do the writing without being detected. The lamp or gas jet is close to the medium’s right hand, where he can reach it. Now, all the persons are seated around the table with their hands on the slates, and each other’s hands or fingers touching one another. The medium takes his right hand away to turn down the light, and his next door neighbor, as soon as the light goes out, feels his (the medium’s) hand or finger replaced. At least, so he thinks. What really happens is this: The thumb of the medium’s left hand is stretched far enough over to touch the hand or finger of the person sitting on the performer’s right hand side. (Fig. 10.) The medium immediately goes to work and produces the writing, and when finished, just as he goes to relight the gas or lamp, he removes the left thumb to create the impression that he has just taken his right hand away again for the light.

Fig. 10.—The Medium Holding the Two Skeptics’ Hands.

Here is a trick I once saw a medium do. He had a number of slates piled on top of the table; he would clean these, one at a time, showing each, and after they had been thoroughly examined, he placed them on the floor. He would then pick them all up together and replace them on the table, and select two of them, put them together, holding them in his hand above his head, would shortly separate them and show one covered with writing. The slates were devoid of all trickery, as was easily proved in allowing them to be thoroughly examined.

Fig. 11.—The Slate under the Carpet.

The explanation is as follows: The floor was covered with carpet. In this there was a slit or cut just large enough to pass or draw a slate through. A slate with writing on one side is previously placed under the carpet, with that side down. (Fig. 11.) The slates, as they are cleaned, are laid on the carpet immediately over or near this concealed one, and, on lifting the slates from the floor, this one is also carried with them, and all placed on the table.

Of course, it is this slate and one of the prepared ones that are afterward used. There is little likelihood of any one taking notice of there being one more slate in the pile.

Some mediums use two single slates, and, after cleaning them on both sides, hold one in each hand. They sit a little way from the table and place the right hand, with the slate, under the chair, as if to draw the chair closer to the table. What the medium really accomplishes is an exchange of slates. There is a little shelf, or drawer, under the seat of the chair. On this lies a slate, one side of which is prepared with writing. The medium picks up the slate and leaves behind in its place the one held in his right hand as he moves the chair. This is a method used to a considerable extent and always successfully.

The following is a clever ruse, ofttimes used by mediums to destroy all traces of the use of the false flap when it is employed. It is the test where the flap is used to cover the writing on one slate, and then that slate is covered with another. Now, if the slates are turned over or reversed, the writing is uncovered and the flap remains in the opposite or underneath slate. Now, to get rid of that flap, the medium deliberately presses his knee against that slate, breaking not only the slate, but also the flap contained in it. The broken flap mingles in with the broken slate, and nobody is any the wiser. Nobody for a moment thinks of picking up the pieces to see if there are one or more slates. Of course, when the slates are broken, it is done secretly under the table, and the medium remarks: “The spirit force is so strong it has smashed the slate.” A test with a single slate that I once saw done was rather neat in its way, and I think it worth describing. The slate was examined and cleaned on both sides, and placed on a small table covered with a little fancy cloth. On lifting the slate afterward, its underneath side was found with writing on it. The top of the table was no larger than the slate. When the slate was laid on the table, the medium remarked: “To convince you there is no trickery about the table, I will remove the cloth;” which he did, with the slate still on or in it, and then replaced the slate and cloth. Now, on this table top was resting another slate covered with writing on one side, and that side upward, and this covered with the table cloth. When the medium picked up the cloth and the slate, which had just been cleaned, he also carried along the second slate with it, which was under the cloth, and in replacing the cloth he simply reversed the sides, laying the first slate on the table, where it was covered by the cloth, and the second one was thus brought to view. It is astonishing how such barefaced and simple devices will deceive the spectator. It is the boldness and air of conviction of his assertions that carry a medium’s test successfully through.
