Of the registered women living by themselves there is little to note. They are more industrious than those in brothels. Many of them have a fixed occupation, but resort to prostitution to increase their income. Money earned in this way is occasionally required for the common necessaries of life, but is more frequently spent in personal gratification, in the way of fine dresses, ornaments, etc., or is appropriated to support the extravagance of some lover, who repays the generosity by a little flattering attention, or an occasional escort to some dancing saloon in the suburbs. The visitors to these women are more select than those to the courtesans hitherto described. In the lowest ranks of prostitution, the common "street-walkers," to be met at all times and places, under all circumstances and of all ages, we find the most prolific sources of infection. A certain, though very small remnant of decency, seconded by the invaluable watchfulness of the police, secures the visitor from disease among the inmates of registered houses, but the street-walker is under no such control. Young girls scarcely more than children, old women almost grandmothers, ply their frightful trade on the "walls" around the city, and in other obscure places, where a trifling present will purchase their caresses. Their principal customers are young boys and very old men, their practices being continued under the shades of evening until the arrival of the night-watch drives them to their wretched dens. The Hamburg police are perfectly cognizant of these proceedings, and wage perpetual war against individuals, but find it altogether impossible to suppress the class, among whom are the habitual tenants of the jail and the House of Correction. No one can differ in opinion from Dr. Lippert, who says, "In this class of women the most pernicious results of prostitution are to be found." Private or domestic prostitution, so widely extended in every great town, exists in less proportion in Hamburg than in other capital cities of the same extent. That disgraceful union in evil occasionally met with on the Continent, in which husband and wife mutually agree to follow their inclinations or lusts untrammeled by each other, is scarcely known. The kept woman is comparatively rare. The expense attendant upon such an appendage of luxury is a serious consideration, and none but the wealthy patrician or successful business man venture on the step. It is assumed, on very good authority, that there are not fifty "mistresses" in Hamburg. Those residing there are under no police control, as in a public point of view they commit no breach of law.
