Ask any medical man about the explanation of hypnotism and kindred other "isms" being accountable for the performance of this trick. I understand that a hypnotist can persuade a patient to believe that his finger is momentarily stiff, and that when released from this suggestion, the patient can remember that it had been made to him. But in order to persuade a person that he sees such a thing as a rope being thrown in the air and so forth, that person must be so much under the influence that when he is released from it he is totally unable to remember what he saw when under the trance. How then, can he describe what he saw when he comes to?

Some people say that photos have been taken of the trick and that when the plate was developed it was found to be blank. As I say, a person to be sufficiently mesmerised to imagine that he sees the trick being done, must perforce be so much under the influence that he cannot remember what he saw or anything that he did when under that influence. How does he know that he took a photo? Or that anyone else took one? Or remember anything at all about it?

I hope that the above arguments will do away with the plea of mesmeric power being accountable for this myth. The plea is to my mind too absurd for words, yet it is wonderful that many people put it forward in all good faith.

While on the subject of photography, let me now point out that although the magicians of Europe and America have for ages been trying to get in touch with the trick, and although the ubiquitous Kodak has been in vogue for at least thirty years, not one single photo or snapshot is available that depicts any part or portion of this trick. If there is such a snapshot, and its owner cares to communicate with me through my publishers, I can get him a good price for the plate or film, even for a copy of the picture. A really handsome price for it.

To sum up I maintain that the trick has never been performed out of doors. That is to say that a rope thrown up into the air has not remained suspended in mid-air, nor has any boy ever climbed up it. That when at the top he has not disappeared and that after his disappearance he did not come down in bits, covered with blood or otherwise.

I further maintain that no one has seen this trick, as described above, or in any way similar to the above description, who can come forward to give the approximate date, of such a performance, the place, and the names of the performer, his assistants, or of any two other persons who saw the trick done at that time and place.

I only wish there might be such a person. We might then get in touch with the Indian Rope trick and Ibn Batuta's character might be vindicated.

I offer Rs. 5000. (£300) to anyone who will show me the Rope Trick in the open. This amount will be payable to anyone who will arrange that the trick is performed for my benefit, in my presence.

The trick must be similar to the description given by Ibn Batuta, and must be brought to a successful conclusion before the reward can be claimed. It is to be performed at a place selected by me, either in India or England.

This offer holds good for five years from the 1st January, 1922.
