Similar experiments have been made even more recently in America. "In Pittsburg, Pennsylvania, in 1891, the houses of prostitutes were closed, the inmates turned out upon the streets, and were refused lodging and even food by the citizens of that place. A wave of popular remonstrance, all over the country, at the outrage on humanity, created a reaction which resulted in a last condition by no means better than the first." In the same year also a similar incident occurred in New York with the same unfortunate results (Isidore Dyer, "The Municipal Control of Prostitution in the United States," report presented to the Brussels International Conference in 1899). There grew up instead the tendency to regulate prostitution, to give it a semi-official toleration which enabled the authorities to exercise a control over it, and to guard as far as possible against its evil by medical and police inspection. The new brothel system differed from the ancient mediæval houses of prostitution in important respects; it involved a routine of medical inspection and it endeavored to suppress any rivalry by unlicensed prostitutes outside. Bernard Mandeville, the author of the _Fable of the Bees_, and an acute thinker, was a pioneer in the advocacy of this system. In 1724, in his _Modest Defense of Publick Stews_, he argues that "the encouraging of public whoring will not only prevent most of the mischievous effects of this vice, but even lessen the quantity of whoring in general, and reduce it to the narrowest bounds which it can possibly be contained in." He proposed to discourage private prostitution by giving special privileges and immunities to brothels by Act of Parliament. His scheme involved the erection of one hundred brothels in a special quarter of the city, to contain two thousand prostitutes and one hundred matrons of ability and experience with physicians and surgeons, as well as commissioners to oversee the whole. Mandeville was regarded merely as a cynic or worse, and his scheme was ignored or treated with contempt. It was left to the genius of Napoleon, eighty years later, to establish the system of "maisons de tolérance," which had so great an influence over modern European practice during a large part of the last century and even still in its numerous survivals forms the subject of widely divergent opinions. On the whole, however, it must be said that the system of registering, examining, and regularizing prostitutes now belongs to the past. Many great battles have been fought over this question; the most important is that which raged for many years in England over the Contagious Diseases Acts, and is embodied in the 600 pages of a Report by a Select Committee on these Acts issued in 1882. The majority of the members of the Committee reported favorably to the Acts which were, notwithstanding, repealed in 1886, since which date no serious attempt has been made in England to establish them again.
