Having rapidly traced the Berlin experience of the various methods of controlling prostitution for nearly three fourths of a century, it only remains to say that the increased evils of illicit prostitution, and the total inability of the police to counteract them; the spread of the venereal disease, and its augmented virulence; the palpable and growing licentiousness of the city; the complaints of public journals; the investigations of scientific men; and the memorials of the citizens generally, reached the royal ear, and induced an ordinance in 1851, restoring the toleration system, and entirely repealing the edict of 1845, which had produced such disastrous results. The experiment of "crushing out" had been fairly tried. The king and his ministers lent all their energy and inclination to the task, and, after six years' attempt, it was admitted to be a futile labor, and entirely abandoned. Berlin will have to suffer for years from the consequences of this misdirected step, for it is an easy matter to abandon all control, but an exceedingly difficult one to regain it. Now that the police are reinvested with their former authority, they strive, by every possible means, to repair the evils of the interregnum. Their most recent regulations are embodied in the following DIRECTIONS FOR KEEPERS PERMITTED TO RECEIVE FEMALES ABANDONED TO PROSTITUTION INTO THEIR HOUSES. "1. The duties hereby imposed upon the keeper are not to be taken to relieve him from the ordinary notices to the police respecting persons taken into his house or employment. "2. The keeper must live on the ground floor of his house, near the outer door, in order to watch all entrance into his house, and to be ready to interfere in case of tumult or uproar therein. "3. The keeper has the right to refuse any person admittance into the house. For preservation of order and quiet in, and in front of his house, the keeper will have the requisite assistance from the police. "4. Dancing and music in the house are strictly forbidden; billiards, cards, and other games are also forbidden, whereof the keeper is to be particularly watchful. "5. In order to avoid quarrels with the visitors, the keeper must affix, in each of his rooms, a list of prices of refreshment, to be previously submitted to the undersigned commission for approval. "6. The agreement which the keeper enters into with the females living in his house must be also communicated to the undersigned commission. In case of dispute as to this agreement between the keepers and the females, both are to address themselves to this commission. "7. Each of the females receives a printed list of directions, which she is strictly to follow. It is the duty of the keeper to make himself well acquainted with these directions, and to see that they be followed.
