A man by the name of D----, or R----, purporting to hail from St. Louis, has enjoyed many years' experience as a hotel 'beat.' He is a tall, not ill-looking fellow, of tolerable address, and generally travels accompanied by his wife and three children, and by a large trunk; his wife sometimes contrives to smuggle in the third child secretly, and to hide it in the room allotted to them, so that only two children appear on the bill. At any rate the bill is never paid whenever settlement is demanded. Mr. D--, or R--, is always found in his apartment seated at the table, busy with an elaborate assortment of manuscripts, and so busy that really at present he cannot be disturbed. To-morrow he will attend to every thing. But to-morrow the birds have flown, or walked out, one by one, from the hotel, and when the trunk, is opened, there is a beggarly array of brickbats, old boxes, old rags, and carpets, the former having served to render the trunk weighty, the latter to prevent any noise or rolling that might excite suspicion. Another adventurer, a bachelor, by the name of M----, affects the eccentric, and, as the day approaches for the handing in of his bill, his eccentricity verges upon madness, till at last, when the document is really tendered, he becomes absolutely crazy--shouts, sings, performs in an antic manner, and declares himself to be the king of the Jews, the President of the United States, or something of that sort. He has sufficient method in his madness, however, to gain the advantage of the hotel proprietors, having on one occasion beaten the Fifth Avenue Hotel out of one hundred and seventy-one dollars in board and lodging. He sometimes is to be seen on Broadway in the guise of a military officer.
