Once, too, I conceived an idea for a variation of this trick, which I am convinced would have created a big sensation, and been heard of all over England, had I been allowed to perform it. My intention was to charter a tug, and allow myself to be dropped over into deep water inside the box. It wouldn’t have made any difference to me, for I could have got out of the corded and locked box while it was under water as easily as I could on dry land.

I had made all the preliminary arrangements. The crew of the tug were to drop me over the side, and if I did not release myself and come to the surface in three minutes by the watch, they were to haul the box up again in order to save my life. Meanwhile it was my intention to have dived under the tug’s bottom after releasing myself, swim quietly away, and remain somewhere in hiding for a couple of days. I could picture to myself the consternation of the crew when, the stipulated three minutes having elapsed, they should haul up the box and find it empty, and also the excitement that would follow on my “mysterious disappearance.” It would have been a splendid “ad.” But, alas! I could not persuade the police that there was no danger in it, and at the last moment the scheme had to be abandoned.

At Bradford Palace, on one occasion when I was there, some trick swimmers were performing in a big tank, and Harry Arnold, the manager, knowing that I rather fancied myself as a swimmer, challenged me to try and see which of us could pick up the most coins under water from the bottom of the tank. I readily agreed, and Harry invited a lot of local people there to witness the trial, which it was arranged should take place after the regular evening performance.

Twenty-four pennies were dumped into the tank, then we threw dice for choice of entering the water. I won. They were my dice.

I told him to go first, which he did, and much to my surprise he gathered up all the coins. Then it was my turn. I dived in the water, but found it was practically impossible to keep down. Nor could I easily find the pennies, for they, being the same colour as the copper bottom of the tank, were practically invisible. In the end I did manage, however, to gather together three or four, and came up again thoroughly exhausted. But I got even with them the next night.

Just before the act was going on I threw a pennyworth of permanganate of potash into the water. The moment the swimmers started diving and stirred up the water, it became blood-red. You can imagine the rest.

Afterwards Harry explained to me how the wheeze was worked. In the first place a man cannot possibly keep down in shallow water where there is no room for him to move about. He invariably bobs up to the surface, like a cork does. Trick swimmers who perform in these tanks always wear a leaden belt round their loins under their tights. Harry had borrowed this, and used it. Also, the pennies he had fished up were fastened together with invisible thread in the corner of the tank. After this explanation I did not feel chagrined any more at having been so completely beaten.

This reminds me that there are tricks in all trades. I was once shown by a pal of mine how to win money at pigeon shooting. I had arranged a match with a man for £5 a side and twelve lunches; 26 yards, 5 traps, best of 11 birds. The arrangement was that each was to supply the other’s birds, the match to take place in a week’s time.

The odds were supposed to be ten to one on my opponent, as I was not shooting very well at the time. But my pal, who was up to all the dodges, assured me that he knew of a scheme that would ensure my winning.

He was himself a great pigeon fancier, and possessed a fine strong lot of homing birds, which he kept in a barn at his place near Ilkley, in Yorkshire. We used to go over to his barn and catch a dozen or so of these birds in the dark, and shut them in a basket such as pigeon fanciers use.
