When the French conquered Algiers in 1830, they found prostitution established there, and prevailing to a large extent. So far as we are able to ascertain, it had always been a leading feature of Algerian society; travelers had noticed it in the seventeenth and eighteenth centuries. In 1830 it was estimated that, with a population of thirty thousand, Algiers contained three thousand prostitutes. We have already had occasion to notice the unreliable character of similar estimates in general, but there is no doubt that the number of lewd women at Algiers under Arab rule was inordinately large. They were mainly Moors, Arabs, and negresses. All were under the control of the chief of the native police--the Mezonar. He kept a list of them, and laid a tax amounting to about two dollars per month on each. As he paid a fixed sum to the government for the privilege of collecting this tax, it was to his interest to increase the number of prostitutes as much as possible, and he appears to have done so. He kept in his employ a number of spies, who watched women suspected of immoral habits, and denounced them whenever they were detected, in which event they were inscribed on the Mezonar's list, and became prostitutes for life. He was empowered to compel every prostitute to discharge the duties of her calling, and was frequently applied to by strangers to supply them with women. He was not allowed, however, to lease women to Christians or Jews. Twice a year the Mezonar gave a public fête, to which all the male inhabitants of Algiers were invited; the prostitutes formed the female portion of the assemblage, and the public officer profited by the increased patronage they obtained during the festivities, as well as by the sale of tickets for the entertainment.[248] It is right also to add that the French found that other feature of Oriental manners, unnatural habits, largely developed at Algiers. The cafés, the streets, the baths, the public places were full of boys of remarkable beauty, who more than shared with the women the favor of the wealthier natives. Owing to a criminal negligence on the part of the French authorities, no systematic endeavor has ever been made to eradicate this shameful vice, which appears still to prevail to an alarming extent.
