This unconquerable vanity, if not turned to use for his good, makes a tough of the lad with more muscle than brains in a perfectly natural way. The newspapers tickle it by recording the exploits of his gang with embellishments that fall in exactly with his tastes. Idleness encourages it. The home exercises no restraint. Parental authority is lost. At a certain age young men of all social grades know a heap more than their fathers, or think they do. The young tough has some apparent reason for thinking that way. He has likely learned to read. The old man has not; he probably never learned anything, not even to speak the language that his son knows without being taught. He thinks him "dead slow," of course, and lays it to his foreign birth. All foreigners are "slow." The father works hard. The boy thinks he knows a better plan. The old man has lost his grip on the lad, if he ever had any. That is the reason why the tough appears in the second generation and disappears in the third. By that time father and son are again on equal terms, whatever those terms may be. The exception to this rule is in the poorest Irish settlements where the manufacture of the tough goes right on, aided by the "inflooence" of the police court on one side and the saloon on the other. Between the two the police fall unwillingly into line. I was in the East Thirty-fifth Street police station one night when an officer came in with two young toughs whom he had arrested in a lumber yard where they were smoking and drinking. They had threatened to kill him and the watchman, and loaded revolvers were taken from them. In spite of this evidence against them, the Justice in the police court discharged them on the following morning with a scowl at the officer, and they were both jeering at him before noon. Naturally he let them alone after that. It was one case of hundreds of like character. The politician, of course, is behind them. Toughs have votes just as they have brickbats and brass-knuckles; when the emergency requires, an assortment to suit of the one as of the other. The story of the tough's career I told in "How the Other Half Lives," and there is no need of repeating it here. Its end is generally lurid, always dramatic. It is that even when it comes to him "with his boots off," in a peaceful sick bed. In his bravado one can sometimes catch a glimpse of the sturdiest traits in the Celtic nature, burlesqued and caricatured by the tenement. One who had been a cut-throat, bruiser, and prizefighter all his brief life lay dying from consumption in his Fourth Ward tenement not long ago. He had made what he proudly called a stand-up fight against the disease until now the end had come and he had at last to give up. "Maggie," he said, turning to his wife with eyes growing dim, "Mag! I had an iron heart, but now it is broke. Watch me die!" And Mag told it proudly at the wake as proof that Pat died game.
