"The grounds of this inspection are two-fold. In one respect they belong to the maintenance of public order: it is needful that no one be withdrawn from the eye of the police, nor find an asylum in such houses. It is likewise expedient that the magistracy take notice of disgraceful and disorderly proceedings, or prevent those which take place too often in the town. The other grounds respect the public health. The habits of debauchery have become so general, and inspection has, for some years, become so difficult, that the most dangerous maladies have increased to an unprecedented extent. All classes of society complain, and call loudly for regulations to restrain these evils. These considerations have moved the General Police Commissary to renew, in full force, the before-enacted laws and regulations, and to order them to be enforced with rigor in the present state of affairs." After the withdrawal of the French, the vigilance of the police authorities seems to have relaxed, if we are to judge by complaints published at the time, in which they are accused of complicity with the unfortunates who infested the streets of Hamburg, and are said, "by the agency of a trifling bribe, to be able to ply their hideous trade unobstructed, and to the great annoyance of the virtuously disposed, who, after certain hours of the evening, are unable to pass along the streets." In 1820, "the previously existing police regulations against prostitutes being proved very ineffectual, insomuch that they infest the public streets and ways, not only to the offense of decency and propriety, but to the endangerment of public order and safety," it was ordered that the regulations should be renewed, and additional powers were given to the police to enforce the registry of individuals coming within the scope of the law. At this time we find some information as to the number of prostitutes, who are stated to be about five hundred, chiefly foreigners, and their receipts from their patrons, but we have no guide to the number of women who pursued their calling privately, which must have been large. The civic administration of the Senator Hudtwalcker is marked by earnest endeavors to control prostitution and restrict it within known bounds. Some of his views on the subject met much opposition. He wished to close up one end of a notorious street, and to wall up the back windows, stationing a watchman constantly at the end left open. After great personal attention to the subject, he published the result of his experience.[265] His principles are those upon which the present police regulations of Hamburg are based. He says:
