Joe's second hobby was to study the hobo monickers written upon or carved into the railroad company's property. From the time his train left the Chicago Terminal until it pulled into the Union Station at Omaha, where Joe's "trip" ended, he employed every spare moment while they stopped at stations or water tanks, to carefully read every hobo sign that the drifters passing to and fro over the line had left behind them, ever hoping to discover a clue to Kansas Shorty's whereabouts by finding his name-de-rail with a date and an arrow beneath it pointing in the direction he was traveling. Joe's third and favorite hobby was to hunt hoboes who dared to beat their way upon his train. He finely discriminated between the man in search of employment, the harmless tramp who had fallen a victim to the wanderlust, the sneaking rogue who "toted" a six-shooter for the special purpose of killing human beings, preferring railroad employees and hoboes, and the rascal who had trained other people's sons to beg a living for him, exactly as an Italian organ grinder would train a performing monkey or bear. Many were the railroad lanterns Joe had to replace for those he broke over the heads of the two latter classes of tramps, especially the last ones, who clung even more obstinately to their road kids than a tiger clings to his prey. The youngsters he had rescued, if he was not able to send them safely home, he would turn over to proper authorities, for well he knew that each one of these runaway boys had not only somewhere a broken-hearted mother waiting for his return, but that, if they were not stopped drifting to the abyss while still young, with the evil training that depraved tramps gave them, it would be merely a matter of time before they too would have learned to destroy and pilfer railroad property; rob box cars and stations, and thus repay with almost brutal ingratitude those who had permitted them to travel unmolested upon their trains.
