The strongest appeal to the instincts of humanity in every right-minded person is made by a consideration of the brutal system employed by these traffickers to in every way exploit their victims, the hardened prostitute as well as the innocent maiden. It is probable that a somewhat larger proportion of the American girls are free from the control of a master; and yet, according to the best evidences obtainable--according to the stories of the women themselves and the keepers of the houses--nearly all the women now engaged in this business in our large cities are subject to pimps, to whom they give most of their earnings, or else they are under the domination of keepers of houses, a condition that is practically the same. It is the business of the man who controls the women to provide police protection, either by bribing the police not to arrest her, or, in case of arrest, to secure bail, pay the fine, etc., to make all business arrangements, to decide what streets, restaurants, dance-halls, saloons and similar places she shall frequent. There are large numbers of Jews scattered throughout the United States, although mainly located in New York and Chicago, who seduce and keep girls. Some of them are engaged in importation, but apparently they prey rather upon young girls whom they find on the street, in the dance-halls, and similar places, and who, by the methods already indicated--love-making and pretense of marriage--they deceive and ruin. Many of them are petty thieves, pickpockets and gamblers. They also have various resorts where they meet and receive their mail, and transact business with one another, and visit. Perhaps the best known organization of this kind throughout this Country was one legally incorporated in New York in 1904, under the name of the New York Benevolent Association. It is, of course, difficult to prove by specific cases the relation of the police to this traffic, and to establish by specific evidence the fact generally accepted that the girls of disorderly house keepers regularly pay the police for protection; but high police officials, prosecuting officers, and social workers in all quarters assert that in many, if not all of our large cities, much corruption of this kind exists. The importation and harboring of alien women and girls for immoral purposes and the practice of prostitution by them--the so-called "white slave traffic"--is the most pitiful and revolting phase of the immigration question. This business has assumed large proportions, and it has been exerting so evil an influence upon our Country that the Immigration Commission felt compelled to make it the subject of a thorough investigation.
