In spite of these efforts, however, it may be safely affirmed that there are not ten boarding houses in the city, which do not contain improper characters. Observers have been struck with the number of handsome young widows who frequent these places. Sometimes these women claim to be the wives of men absent in the distant Territories, or in Europe, and pretend to receive letters and remittances from them. In nine cases out of ten such women make their living in a manner they do not care to have known. They conduct themselves with the utmost propriety towards all persons living in the house with them, and are considered ladies by even acute judges. These same judges are sometimes a little startled to meet these virtuous dames in places where _ladies_ are never seen. Of course the secret is kept, and the woman continues to deceive her other companions. Landladies are the object of the especial attentions of swindlers, and suffer very much from them. All sorts of expedients are resorted to by the unprincipled to live without paying their board. A FASHIONABLE SWINDLER. Last winter a "gentleman" called upon a lady who presides over a fashionable boarding-house in Lexington avenue, and introducing himself as William Aspinwall, of the "Howland and Aspinwall branch," obtained a room on the second floor. This apartment he occupied for three weeks, constantly "promising" the lady of the house money, but as constantly "being disappointed in his remittances from his friends, but if the lady would wait but a day or two longer he would apply, if his remittances did not arrive, in person to Mr. Aspinwall and obtain a thousand or two." At last, one day this pretended scion of the Aspinwalls vanished, leaving his trunk behind him, which, upon examination, was found to be very full and very heavy indeed, but with bricks and rags only. All Mr. Aspinwall's wardrobe being carried on his precious person. A letter was found, however, which proved that his real name was Charles H, or at least that he had been known at times by that title. A SHARP GAME.
