Some say that the four kings represent those famous champions of antiquity--David, Alexander, Julius Caesar, and Charlemagne; and that the four queens, Argine, Pallas, Esther, and Judith, are the respective symbols of majesty, wisdom, piety, and fortitude; and there can be no doubt, if you look attentively on the queens of a pack of cards, you will easily discern the appropriate expressions of all these attributes in the faces of the grotesque ladies therein depicted. The valets, or attendants, whom we call knaves, are not necessarily 'rascals,' but simply servants royal; at first they were knights, as appears from the names of some of the famous French knights being formerly painted on the cards. Thus a pack of cards is truly a monument of the olden time--the days of chivalry and its numberless associations. In addition to the details I have given in the previous chapter respecting the probability of holding certain cards, there are a few other curious facts concerning them, which it may be interesting to know. There is a difference in the eyes of two of the knaves--those of diamonds and hearts, more apparent in the old patterns, suggesting the inference that they are blind. This has been made the basis of a card trick, as to which two of the four knaves presenting themselves would be selected as servants. Of course the blind ones would be rejected. A bet is sometimes proposed to the unwary, at Whist, but one of the party will have in his hand, after the deal, only one of a suit, or none of a suit. The bet should not be taken, as this result very frequently happens. Lastly, there is an arithmetical puzzle of the most startling effect to be contrived with a pack of cards, as follows. Let a party make up parcels of cards, beginning with a number of pips on any card, and then counting up to twelve with individual cards. In the first part of the trick it must be understood that the court cards count as ten, all others according to the pips. Thus, a king put down will require only two cards to make up 12, whereas the ace will require 11, and so on. Now, when all the parcels are completed, the performer of the trick requires to know only the number of parcels thus made, and the remainder, if any, to declare after a momentary calculation, the exact number of pips on the first cards laid down--to the astonishment of those not in the secret. In fact, there is no possible arrangement of the cards, according to this method, which can prevent an adept from declaring the number of pips required, after being informed of the number of parcels, and the remainder, if any. This startling performance will be explained in a subsequent chapter--amusing card tricks.
