“I have here three wooden dice, with a cover for each of them.” (Take off all three covers, placing each beside its own die. Then, placing one of them on the end of your wand, advance with it to the company, tacitly inviting anyone who pleases to take it off and examine it.) “I use these covers to spare the feelings of the dice at the critical moment. Like myself, they are rather bashful. They don’t mind doing the Jekyll and Hyde business, but they don’t like to be seen doing it. By the way, there is a very ancient trick (believed to have been invented by Noah in the Ark, to amuse the boys on a wet Sunday), which is worked by means of a sham die fitting over the real one. Please take my word for it that I do not use any such stale device. If I did, you may be quite sure I should not mention it. These are all three genuine dice. They are rather too large to play backgammon with, but save as to size, they are merely big brothers of the regular article. Most of you know, no doubt, that in properly made dice, the points on opposite sides always together make seven. Notice please, that each of these dice has the numbers placed correctly.” (Taking up one of the dice and turning it about.) “You see, five on this side, two on that; together, seven. Three on this side, four on that; together, seven. Six on this side, one on that; again seven.”
This is repeated, in a casual way, with the other two dice, the object being two-fold, viz.: first, by showing all six sides, to induce the belief that the dice are solid, and secondly, to enable the performer, in replacing them on the table, to turn each the other way up, so as to bring the loose side undermost. This is best done by placing the thumb on top of the die, with the first and second fingers behind it, then tilting the die over a little to the front, and slipping the two fingers underneath it. After showing it on all sides, as above mentioned, it is an easy matter to replace it with the loose side undermost, as desired.
“Now, as it happens, I have no immediate use for dice, but I want to show you a pretty little effect with billiard-balls. Naturally, the thing to be done is to change the dice into billiard-balls. It’s quite easy, if you are provided with my patent quick-change combination dice. All you need to think about is to take care to have even numbers in front.” (You turn the dice accordingly, and in so doing lift each die a little, and shift it forward a couple of inches or so, leaving the loose side undisturbed just behind it, the ball travelling forward with the die, though still covered by it.) “You don’t see why they should show even numbers? Because they would look ‘odd’ if they didn’t. Quite simple,—when you know it. Now I cover all three dice over, to spare their blushes, as I explained just now. I wave my wand over them and say, ‘Presto! Proximo! Change!’ And we shall find the dice have all turned to billiard-balls.”
The right hand lifts the first cover, pressing its sides sufficiently to lift the die within it, exposing the ball, and in bringing it down again lands it close to one of the wells of the table. The exposed ball is picked up with the left hand, and while the attention of the company is attracted in that direction, the die is allowed to slide out of its case into the well, after which the ball and cover are brought forward and handed to someone of the company.
The other two balls are now uncovered in the same way, but in this case the dice may be left in their covers, the offer of the first cover, found empty as above, having sufficiently proved that they really disappear.
“Well, we have got our three billiard-balls. Good, so far. Next, can any gentleman oblige me with the loan of a billiard table? Nobody offers: that’s unfortunate. Well, does any gentleman happen to have a cue about him. No again? Well, perhaps it would be ‘cuerious’ if any gentleman had. I beg your pardon, it slipped out unawares. It shall not occur again.
“It’s unfortunate that I can’t borrow a billiard table and a cue, because it prevents my showing you my celebrated break of ninety-three off the red with my eyes shut. When I showed it to Gray, he turned green, but that is another story. You don’t believe it? Well, I told you it was a story.
“Anyhow, as we have got the balls, we must do something with them.”
