The confidence men, who invite the incoming visitor to view the scene of the great explosion on the lake front, and suggest trips to other places where startling events have not occurred, discover, by skillful questioning, the weaknesses of their dupe. They arouse his innate, but dormant, wish to take a chance at some game that seems to him certain of a rich return. He is easily induced to play and allowed to win a small stake, merely to excite greater interest and establish the conviction that he can "beat the game." Naturally he plunges ahead, until the moment comes, set by his trappers, when he is cheated, robbed and goes "flat broke." The dupe may, or may not, report his loss to the police. If he does, and it happens to be one of consequence, detectives may be detailed to search for the swindlers; but if the loss is small in amount, however important to the loser, the dupe is more likely to be laughed at than aided by the officers of the law. To this class belong cabmen who rob drunken men, and "divvy" with the police; commission houses, which secure consignments of goods for sale by false representations; grocery grafters, who solicit throughout the country orders for groceries, claiming to represent wholesale houses, ship an inferior grade and collect C. O. D. at the prices charged for the superior grade; Board of Trade sharks, who "welch" their clients' money by charging up fictitious losses, when the figures will not appear to lie; the false claimants for personal injuries alleged to have been caused through the negligence of wealthy corporations, such as street car lines, manufacturing companies and rolling mills, or by the city, from defective sidewalks, unguarded street excavations, etc., etc.; bakers who sell unlabeled and underweight bread; the gold brick and gold filings sharper; the electric and mining stock swindler, and the advertiser seeking a governess to accompany himself and family abroad. These men have "irresistible tendencies" to work their several games. They cannot help it, they say. Like kleptomaniacs, or "Jack the Hair Clipper," they are impelled by nature to the commission of their crimes. In their own judgment they ought not to be punished, because they are the victims of defective brains. But they are just as cunning as the hair clipper, just as conscious that they are law breakers as he was when he mailed to the Chief of Police in his own words the following note, enclosing some of the braids of hair he had clipped from the head of a young girl, viz: "A clue for J. K.'s cheap skates. Will send more when I get cheap stuff like this. Jack."
