This squeamishness conquered, the beginner will have to be careful not to become hard and pessimistic. There is a good deal to be said in excuse of a police officer who develops these traits of character,--the life he leads is itself often hard,--but if they dominate his nature he learns to look upon the world in general merely as a great collection of human beings, any one of whom he may have to arrest some day. He sees so much that is "crooked" that he is in danger of thinking that he sees crime and thieves wherever he turns, and unless he is very cautious he will drift into a philosophy which permits him to be "crooked" also, because, as he thinks, everybody else is. If the beginner has lived in a society where courtesies and kindnesses, rather than insults and scoldings, have prevailed, he will also find it hard for awhile to appreciate the fact that a police officer is a peacemaker, and not an avenger. Wherever he goes, and no matter what he does, he is a target for the nasty slings of rowdies and a favourite victim of the "roastings" of thieves. In tramp life I have had to take my share of insults, and until I experimented with the police business I thought that as mean things had been said to me as a man ought to stand in an ordinary lifetime, but on no tramp trip have I been berated by criminals as severely as during my recent experience as a railroad police officer, and yet it was my duty not to answer back if a quarrel was in sight. Not all, however, in the policeman's life is exasperating and discouraging. But few men have so many opportunities of doing good, and of keeping track of people in whom they have taken an interest. Nothing has pleased me more in my relations with the outcast world than the chance I had as a railroad patrolman to help in sending home a penitent runaway boy. He had left Chicago on the "blind baggage" of a passenger train to get away from a tyrannical stepfather, and he fell into our hands as a trespasser and vagrant several hundred miles from his starting-point. It was a pitiful case with which no officer likes to deal according to the requirements of the law, but we had to arrest him to rescue him from the local officers of the town where he had been apprehended; if he had been turned over to them the probability is that he would have been put on the stone-pile with the hardened tramps, and when released would have drifted into tramp life. We took him to headquarters on the train, and the general manager of the railroad gave him a pass home, where he has remained, sending me a number of weekly accounts about himself. I report the incident both to show the opportunities in a policeman's life, and to give a railroad company credit for a kind deed which has probably preserved for the country a bright lad who would otherwise have been an expense and trouble to it as a vagabond and criminal.
