Slumming parties, composed of respectable men and women whose morbid curiosity has been aroused by tales of the inconceivable vices forming the night-life of the demi-monde, are not infrequently found "going down the line" dropping into the houses of prostitution, viewing the bar, the private rooms, the dance hall, the crap games and the vicious surroundings of the all night pest holes. To slum has, in a measure, become a fashionable fad. Its purpose is, not to carry into these haunts the example of a better life, but to cater to a dangerous spirit of inquiry, upon the principle that excitement, even though it be found in the midst of the garbage boxes of vice, is relished now and then by the best of mankind. The only indication of a world outside, in which Christian principles prevail, is occasionally to be found, when some of the women garbed in the simple uniform of either the Salvation or Volunteer Army, engaged in rescue work, or in scattering a hopeful word, through the medium of their publications, pass among the crowd, receiving in most instances respectful attention, and, at times, but rarely, a jeer from some drunken sot or wrecked woman. The houses of ill fame, whose stained glass windows with suggestive female figures in the nude advertise the abode of the scarlet woman, are as luxuriously furnished as is the home of the wealthy and respectable citizen. These "creatures of sale," as Shakespeare puts it, are as clearly distinguished in public as members of the demi-monde, as if the Julian laws were in operation in Chicago. In early Rome, under these laws, the courtesan was compelled to dye her hair blue or yellow. Like the Grecian courtesan whose distinctive mark of her calling was blonde hair, the strumpet of today generally favors a fashion coming down from the past ages. The passer-by of these abodes of sensuality is invited by open solicitation or unmistakable gesture to enter them, especially by the more degraded of the women. A studied decorum is maintained in some of the parlors of the older establishments, presided over by a proprietress advanced in years, plentiful in wealth, and dictatorial in management. Harsh rules are prescribed for the maintenance of the condition of slavery into which the girls have fallen. Debts to the house tie them to it by bands too strong to be easily broken, in what are termed the aristocratic branches of this nefarious trade. These women are none the less free from indulgence in unnatural practices than are those of houses of reputed lower degrees of depravity. White and colored alike revel in the same scenes of carnality which, fragments of history state, prevailed in the declining days of Rome and of Greece. The inmates of the lowest of these houses, both in dress, or in the absence of it, and in deportment, follow the habits of the Dicteriades, or low down prostitutes, of Piræus in the time of Pericles. Their appearance in the reception parlors in a state of
