A peculiarity of the Twenty-ninth Police Precinct of the city, in which the majority of the better class of houses are located, "is the large number of lady boarders, who do nothing, apparently, for a living. They live in furnished rooms, or they may board in respectable families. They leave their cards with the madame of the house, together with their photograph. They live within a few minutes' call, and when a gentleman enters the parlor he has a few minutes' chat with the madame, who hands him the album. He runs his eye over the pictures, makes his choice, and a messenger is dispatched for No. 12 or 24. These are what may be termed the day ladies, or outside boarders. Some of them are married, living with their husbands, who know nothing of what is going on, and it may be some of them have shown the readers of the _Sun_ how cheap they can keep house, dress well, and put money in the bank beside, on a given weekly income of their husband. Those ladies who hire furnished rooms all dine at the restaurants, but they are never found soliciting men in the street. True, in the restaurant they may accept a recognition, but a man has to be careful what he is about." EFFORTS TO BREAK UP THESE HOUSES. "Twenty years ago, when Matsell was Chief of Police, he used to try and break up the most notorious houses by stationing a policeman at the door, and when any one went in or out, the light from a bull's eye lantern was thrown in the face of the passer out or in. That has never been effective. Captain Speight tried it in the case of Mrs.----, who keeps the most splendidly furnished house in West Twenty-fifth street. She owns the house, and has a few boarders who pay her fifty dollars a week for board, and ten dollars a bottle for their wine, and twenty- five per cent, on the profits of her boarders. The attempt was made to oust this woman, but she very politely told the captain that he might honor her as long as he pleased with the policeman and his lantern, but she could stand it as long as he could; she owned the house, and she meant to live in it; nothing could be proven against it, and they dare not arrest her. The consequence was that after a time the bull's eye was withdrawn." A NEW RUSE ADOPTED.
