So much for the forces that help to jar men and boys loose, forces that have doubled in the last twenty years and are still increasing: New labor-saving machines, throwing more men out of work, new machines to make use of child labor, new machines to speed up the American pace and so turn out more cripples; rush and slack seasons, demanding more and more armies of surplus labor; the swift growth of industry, bringing to America millions of immigrants, over half of them young men who come alone; and most of all, the railroads, demanding increasing throngs of nomadic camp workers; the railroads, “the real hot circus,’’ tempting boys to the Road and giving to all kinds of hoboes easy and free means of travel. Lastly, the huge tenement hives, where year by year people are packed in tighter, where year by year life grows more nervous and tense and restless. And deep under all these conditions, responding to the chances they offer, the old human love of the Road that lies deep down in the souls of men — the “wanderlust” of humanity.Poole, Ernest. “A Clearing-House for Tramps.” Everybody’s Magazine, vol.
