I therefore venture to hope that in serving my own need I may also serve the need of a rapidly growing public when I set down for rational consideration the temptations surrounding multitudes of young people and when I assemble, as best I may, the many indications of a new conscience, which in various directions is slowly gathering strength and which we may soberly hope will at last successfully array itself against this incredible social wrong, ancient though it may be. Hull House, Chicago. CHAPTER I AN ANALOGY In every large city throughout the world thousands of women are so set aside as outcasts from decent society that it is considered an impropriety to speak the very word which designates them. Lecky calls this type of woman "the most mournful and the most awful figure in history": he says that "she remains, while creeds and civilizations rise and fall, the eternal sacrifice of humanity, blasted for the sins of the people." But evils so old that they are imbedded in man's earliest history have been known to sway before an enlightened public opinion and in the end to give way to a growing conscience, which regards them first as a moral affront and at length as an utter impossibility. Thus the generation just before us, our own fathers, uprooted the enormous upas of slavery, "the tree that was literally as old as the race of man," although slavery doubtless had its beginnings in the captives of man's earliest warfare, even as this existing evil thus originated. Those of us who think we discern the beginnings of a new conscience in regard to this twin of slavery, as old and outrageous as slavery itself and even more persistent, find a possible analogy between certain civic, philanthropic and educational efforts directed against the very existence of this social evil and similar organized efforts which preceded the overthrow of slavery in America. Thus, long before slavery was finally declared illegal, there were international regulations of its traffic, state and federal legislation concerning its extension, and many extra legal attempts to control its abuses; quite as we have the international regulations concerning the white slave traffic, the state and interstate legislation for its repression, and an extra legal power in connection with it so universally given to the municipal police that the possession of this power has become one of the great sources of corruption in every American city. Before society was ready to proceed against the institution of slavery as such, groups of men and women by means of the underground railroad cherished and educated individual slaves; it is scarcely necessary to point out the similarity to the rescue homes and preventive associations which every great city contains.
