If you look up to the second floor, you may see a pretty, but not over fresh looking young woman, gazing down into the street. She meets your glance with composure, and with an expression which is a half invitation to "come up." She is used to looking at men, and to having them look at her, and she is not averse to their admiration. Her dress is a little flashy, and the traces of rouge are rather too strong on her face, but it is not a bad face. You may see her to-night at the --- Theatre, where she is the favorite. Not much of an actress, really, but very clever at winning over the dramatic critics of the great dailies who are but men, and not proof against feminine arts. This is her home, and an honest home, too. To be sure it would be better had she a mother or a brother, or husband--some recognized protector, who could save her from the "misfortune of living alone;" but this is Bleecker street, and she may live here according to her own fancy, "and no questions asked." On the floor above her dwells Betty Mulligan, a pretty little butterfly well known to the lovers of the ballet as Mademoiselle Alexandrine. No one pretends to know her history. She pays her room rent, has hosts of friends, but beyond this no one knows anything. Surmises there are by the score, and people wonder how mademoiselle can live so well on her little salary; but no charges are made. People shrug their shoulders, and hint that ballet girls have resources unknown to the uninitiated. The rule here is that every one must look after himself, and it requires such an effort to do this that there is no time left to watch a neighbor's shortcomings. In the same house is a fine-looking woman, not young, but not old. Her "husband" has taken lodgings here for her, but he comes to see her only at intervals, and he is not counted in the landlady's bill. Business keeps him away, and he comes when he can. Bleecker street never asks madame for her marriage certificate, nor does it seek to know why her numerous friends are all gentlemen, or why they come only when the "husband" is away. Honest, hard-working men come here with their families. Their earnings are regular, but small, and they prefer the life of this street to the misery of the tenement house. Others there are who live in the street, and occupy whole dwellings with their families, who stay here from force of habit. They are "slow" people, dull of comprehension, and to them the mysteries of their neighborhood are a sealed book. Yet all are regarded as persons whose characters are "not proven," by the dwellers outside the street. Money is a power in Bleecker street. It will purchase anything. Much is spent by those who do not dwell here, but come here to hide their secrets. Women come here to meet other men besides their husbands, and men bring women here who are not their wives. Bleecker street asks no questions, but it has come to suspect the men and women who are seen in it.
