The charge of impatience, which is so often brought against him, may be explained in the same way; and the tramps are again good illustrations. As a class they are the most patient people imaginable, and are able to endure pleasantly any amount of ruffling circumstances. Where, for example, is there a calmer and more stoical human being than the American "hobo," waiting through rain or shine at the railway watering-tank for the freight-train that shall carry him farther on the road? He will stay there for days, if necessary, rather than pay the regular fare on the passenger-trains; and nothing arouses his scorn more than the dilettante, or "gay-cat," as he calls him, who gives up waiting and buys a regulation ticket. The criminal, after a certain age, often lacks this ability to hang on; but his nerves and general equipoise have been disturbed by imprisonment. Even the tramp is a less patient person in county jails than he is in the open; but his stay there is so short, and the confinement, compared with that in convict prisons, is so much easier to bear, that he soon recuperates. I can write from personal experience on this point; for, as an American tramp, I have had to take my share of jail life, and I have never been so nervous and impatient as when undergoing it. In the open, on the other hand, I have never been so healthy and under control. If a few days' confinement can have such an effect upon an absolutely voluntary prisoner, what must be the effect of years of this sort of life upon the man who hates prison as he does poison, and is not sure that when he is released an officer may not be waiting to read him a warrant for another arrest? Criminologists who believe in the innate nervous weakness of the criminal would do well to test their own nerves during even voluntary residence in prison-cells in order to estimate their power to disturb a natural equilibrium. It is also said that the criminal is more or less an epileptic. Lombroso makes a great deal of this supposition; and there are other students of the subject who go quite as far as he does. I have never met a pure epileptic criminal on the road, and I cannot recall having heard the subject discussed by tramps or criminals in any way that would lead me to believe the disorder at all common among them. Among tramps a favorite trick is to feign epilepsy; and I have seen it done with a fidelity to the "real thing" that was remarkable. Whether or not criminals also feign in prison, I am not prepared to say; but if they are as clever as tramps at it, I can well believe that they might deceive even the very elect among specialists. I have also failed to find insanity common among criminals. Among those under twenty-five years of age, I have never known one clear case; and the few cases that I have known after that period have been men who have had long sentences in prison, and whose confinement, I have no doubt, has had much to do with their mental derangement.
