"Yes," returned Chichester, opening the parcel and displaying its contents upon the table. "Here are the scratched dice, you see. These must be used upon a bare table, because it is necessary to judge by the sound of the dice in the box whether they are on the scratched side or not. You understand that a hole has been drilled in the centre pip of the five in this die, and in the ace of the other; a piece of ebony is then inserted, with a very small portion projecting. These dice cannot, therefore, fall perfectly flat, when the five side of the one and the ace of the other are underneath on the table; and it is very easy for the thrower just to move the box the least thing before he lifts it, to that the sound may tell him whether the scratched side is down or not. But you are to recollect that a man must be very drunk when you can use them with any degree of safety."
"I should think so, indeed," said Sir Rupert.
"I can assure you that no implements of our craft are, on certain occasions, more destructive than these," observed Chichester.
"And what is the use of these slight scratches upon the dice?"
"To assist the eye in manipulating them. But here," continued Chichester, holding up a dice-box, and surveying it with a species of paternal admiration,—"here is a famous antidote to fair dice. Don't you see that when fair dice are used, you must introduce an unfair box. Many a greenhorn may have heard of loaded dice, and so on; but very few know that there is such a thing as the Doctor Dice-box. Honour to the man, say I, who invented it. If you judge by the outside of this box, it is a very fair-looking one; but just put your finger into it, and you will feel that no less than three-quarters of the inside are filled up, so that there is now only just space enough left in the middle for the dice to fit in. Towards the top the sides grow larger and smoother. The dice, you see, rattle by rising up and down, when shaken briskly, but do not change their position. All that you have to do is to put them in, in the first instance, with a view to the way in which you want them to come up."
"So that if you want to throw a six and a five, put the dice into the box with the ace and the two uppermost," said the baronet.
"Precisely," answered Chichester. "A fair box, you know as well as I do, has one or more rims inside, against which the dice must turn in coming out."
