During the summer of 1868, a young lady residing in a respectable part of the city, was decoyed by an elderly woman, (under the pretence of being able to introduce the young lady to a cheap dressmaker,) into a low neighborhood, where she was seized by two men, dragged into a hovel, and there held by the ruffians, while the old hag who had decoyed her thither, with a pair of shears cut off the larger portion of her luxuriant hair--to fill, as she coolly informed her victim, 'an order from a wig-maker.' The screams and struggles of the poor dupe were of no avail, and when finally thrust out of doors by her tormentors, she was so frightened that she wandered mechanically along, up and down streets, until she met a policeman, who, on hearing her story, called a carriage and had her conveyed home, but was not able from her incoherent and inaccurate description, either to identify the place where the outrage was committed, nor the people by whom it was perpetrated. [Illustration: The thieves' exchange--a drinking saloon where pawnbrokers go to buy stolen goods.] THE THIEVES' EXCHANGE. There is, in the Eighth Ward of the City, an "Exchange," where the light-fingered gentry congregate and interchange confidential intelligence, the news of their profession, and exchange the stolen goods temporarily in their possession. Attached to this is the wareroom of the proprietor, who is simply a receiver of stolen goods. There are many of these places in the city. The agent of the New York Prison Association, in one of his reports, says: When a burglar has successfully entered a store, and carried off a large amount of property, in the form of fine goods, this property itself is of no more use to him than the dust of the street. He does not want to wear lace or jewelry. He does not need watches or pencil- cases. He cannot eat cameos or vases. He, therefore, at once takes his plunder to his 'fence,' and receives from him, in money, such a price as is usually agreed upon. It is very difficult to ascertain, with any degree of exactness, what proportion of the value of the plunder is realized on the average by the thief; but from the best information we could obtain, we feel confident it does not exceed one sixth. A man whom we met in one of the jails, told us he was unsuccessful at first, because he had received no instructions in the art. We asked him what he deemed the most important information to be obtained by a tyro in the business. He answered promptly: 'To know the names and characters of all the "fences" within a circle of thirty miles.' He could do little or nothing without this knowledge.
