Those quick folk of the fraternity whom he encountered and who from time to time lost money to Casino Joe, never once suspected his victories to be a result of mere memory. They held that some cheat took place. But as it was not detectable and no man might point it out, no word of fault was uttered. Joe took the money and never a protest; for it is as much an axiom of the gaming table as it is of the law that “Fraud must be proved and will never be presumed or inferred.” With no evidence, therefore, the losing gamblers made no protesting charge, and Joe went forward collecting the wealth of any and all who fought with him at his favorite science. Casino Joe, as I have said, accounted for his mastery at casino by his power to “Tell the last four,” and laid it all to memory. “And yet,” said Joe one evening as I urged him to impart to me his secret more in detail, “it may depend on something else. As I’ve told you, it’s my gift. Folk have their gifts. Once when I was in the town of Warrensburg in Western Missouri, I was shown a man who had gifts for mathematics that were unaccountable. He was a coarse, animalish creature, this mathematician; a half idiot and utterly without education. A sullen, unclean beast of a being, he shuffled about in a queer, plantigrade fashion like a bear. He was ill-natured, yet too timid to do harm; and besides a genius for figures, his distinguishing characteristics were hunger measured by four men’s rations and an appetite for whiskey which to call swinish would be marking a weakness on one’s own part in the art of simile. Yet this witless creature, unable to read his own printed name, knew as by an instinct every mathematical or geometrical term. You might propose nothing as a problem that he would not instantly solve. He could tell you like winking, the area of a seven or eight-angled figure so you but gave him the dimensions; he would announce the surface measurements of a sphere when told either its diameter or circumference. Once, as a poser, a learned teacher proposed a supposititious cone seven feet in altitude and with a diameter of three feet at the base, and asked at what distance from the apex it should be divided to make both parts equal of bulk and weight. The gross, growling being made correct, unhesitating reply. This monster of mathematics seemed also to carry a chronometer in his stomach, for day or night, he could and would--for a drink of rum--tell you the hour to any splinter of a second. You might set your watch by him as if he were the steeple clock. I don’t profess,” concluded Casino Joe, “to either the habits or the imbecility of this genius of figures, yet it may well be that my abilities to keep track of fifty-two Cards as they appear in play and know at every moment--as a bookkeeper does a balance--what cards are yet to come, are not of cultivation or acquirement, but were extant within me at my birth.” When Casino Joe appeared in the Bowery he came to gamble at cards.
