The arrangement of the table being once under- stood, the number associated with any given card in the club suit suggests itself automatically, e.g., the seven of clubs is likewise No. 7 in the list. To ascertain the name of the card corresponding to any of the higher numbers, all that is needed is to subtract from that number 13, or such higher mul- tiple of thirteen as the case will admit, and the difference will represent its position in its own suit. Suppose, for instance, that the performer desires to know what card answers to the number 20. Deducting thirteen from 20, the remainder, 7, tells him that the card is the seventh (i.e. the seven) of the second suit, viz., hearts. If he wants to know the name of No. 29, he deducts 26, when the remainder, 3, tells him that the card is the three of the third suit, spades. If the card be No. 40, the number to be deducted will be 39, and the remainder, 1, tells him that the card is the first of the fourth suit, viz., the ace of diamonds. After a very few trials, this little exercise in mental arithmetic becomes so familiar that the calculation becomes practically instantaneous. Going a step further; with each of the six pages |
