The various night lines of steamers running from New York city, are literally overrun with abandoned women, seeking companions. The Albany and the Boston lines are made intensely disagreeable by such persons. A correspondent of one of the New Jersey papers, thus relates his experience on board of one of the magnificent vessels of a Boston line. The grand saloon is filled with a throng of travellers listening to the sweet music discoursed by a band in the upper gallery, employed for the season by the company. One cannot but remark, with mingled pain and indignation, the large number of brazen-faced prostitutes and professional gamblers who saunter up and down the saloon and galleries, seeking their prey among the unsuspecting passengers. * * * * * If a gentleman is seated alone, along comes one of these painted wretches, boldly addressing him, and to escape her horrible proffers, he must seek some other part of the boat, or follow the example of every respectable lady, by occupying his stateroom at an early hour in the evening. It is really getting to be exceedingly unpleasant and disagreeable for a lady to travel by this line, even if accompanied by a gentleman; and let no one permit a female relative or friend to take this route alone, if they have the slightest regard for the decencies and proprieties of life. While the band was discoursing sweet strains of music, shrill screams were heard proceeding from the forward saloon. The passengers rushed to the scene. A young woman was being carried by main force, exerted by the servants, below. She struggled fiercely, biting, striking and cursing! What a horrible sight. One observer, at least, earnestly trusts he may never behold such an one again. She was one of the courtesans who had been parading up and down the saloons all the evening. She had inveigled an unsophisticated countryman into a stateroom and robbed him. He reported her to the captain, and threatened public exposure of the transaction before he could procure assistance! And now her screams can be plainly heard, resounding through, the gilded saloons, above the run of the machinery and strains of the musicians. PANEL THIEVING.
