No picture of the ways of the Metropolis would be complete which did not force upon the reluctant reader some realization of the extent to which new and hideous incitements to vice were spreading. To say that among the leisured classes such practices were raging like a pestilence would be no exaggeration. Ten years ago they were regarded with aversion by even the professionally vicious; but now the commonest prostitute accepted them as part of her fate. And there was no height to which they had not reached—ministers of state were enslaved by them; great fortunes and public events were controlled by them. In Washington there had been an ambassador whose natural daughter taught them in the houses of the great, until the scandal forced the minister’s recall. Some of these practices were terrible in their effects, completely wrecking the victim in a short time; and physicians who studied their symptoms would be horrified to see them appearing in the homes of their friends. And from New York, the centre of the wealth and culture of the country, these vices spread to every corner of it. Theatrical companies and travelling salesmen carried them; visiting merchants and sightseers acquired them. Pack-pedlers sold vile pictures and books—the manufacturing or importing of which was now quite an industry; one might read catalogues printed abroad in English, the contents of which would make one’s flesh creep. There were cheap weeklies, costing ten cents a year, which were thrust into area-windows for servant-girls; there were yellow-covered French novels of unbelievable depravity for the mistress of the house. It was a curious commentary upon the morals of Society that upon the trains running to a certain suburban community frequented by the ultra-fashionable, the newsboys did a thriving business in such literature; and when the pastor of the fashionable church eloped with a Society girl, the bishop publicly laid the blame to the morals of his parishioners! The theory was that there were two worlds, and that they were kept rigidly separate. There were two sets of women; one to be toyed with and flung aside, and the other to be protected and esteemed. Such things as prostitutes and kept women might exist, but people of refinement did not talk about them, and were not concerned with them. But Montague was familiar with the saying, that if you follow the chain of the slave, you will find the other end about the wrist of the master; and he discovered that the Tenderloin was wreaking its vengeance upon Fifth Avenue. It was not merely that the men of wealth were carrying to their wives and children the diseases of vice; they were carrying also the manners and the ideals.
