The visitors to these houses are men of means. No one without a full pocket can afford such indulgence. Visitors are expected to spend considerable money for wine, which is always furnished by the proprietress at the most exhorbitant prices, and at a profit of about 200 per cent. A large part of her revenue is derived from such sales, and she looks sharply after this branch of the business. The shamelessness with which men of standing and prominence, many of whom are fathers of families, resort to these houses and display themselves in the parlors is astounding. Indeed, the keeper of one of the most fashionable houses boasts that married men are her principal customers. Sometimes the visitor desires that his visits shall not be known. For such persons there are private rooms, where they are sure of seeing no one but the proprietress and the woman for whom their visit is intended. These houses are largely attended by strangers visiting Chicago; these, thinking themselves unknown in a large city, care little for privacy, and boldly show themselves in the general parlors. The proportion of married and middle-aged men among them is very great. You will find among them lawyers, physicians, judges of the courts, members of congress, and even ministers of the gospel, from all parts of the country. This may seem a startling assertion, but the police authorities will confirm it. If the secrets of these places as regards their visitors could be made public there would be a terrible rupture in many happy families throughout the land, as well as in the metropolis. Men who at home are models of propriety, seem to lose all sense of restraint when they come to Chicago. These same gentlemen would be merciless towards any female member of their families who should display a similar laxity. To return to the women: the inmates of the first-class houses rarely remain in them for more than two years. Their shameful and dissipated lives render them by this time unfit for companionship with their aristocratic associates. The proprietress quickly detects this and remorselessly orders them from her house. She knows the fate that awaits them; but her only care is to keep her house full of fresh and attractive women.
