SIR,—Having read in your paper of the 26th October last, a paragraph respecting an old gentleman by the name of _Knickerbocker_, who was missing from his lodgings; if it would be any relief to his friends, or furnish them with any clue to discover where he is, you may inform them that a person answering the description given, was seen by the passengers of the Albany stage, early in the morning, about four or five weeks since, resting himself by the side of the road, a little above King’s Bridge. He had in his hand a small bundle, tied in a red bandana handkerchief; he appeared to be travelling northward, and was very much fatigued and exhausted. A TRAVELLER. _From the same, November 16, 1809._ _To the Editor of the Evening Post_: SIR,—You have been good enough to publish in your paper a paragraph about Mr. _Diedrich Knickerbocker_, who was missing so strangely some time since. Nothing satisfactory has been heard of the old gentleman since; but _a very curious kind of a written book_ has been found in his room, in his own handwriting. Now I wish you to notice him, if he is still alive, that if he does not return and pay off his bill for boarding and lodging, I shall have to dispose of his book to satisfy me for the same. I am, sir, your humble servant, SETH HANDASIDE, Landlord of the Independent Columbian Hotel, Mulberry Street. _From the same, November 28, 1809._ LITERARY NOTICE. INSKEEP & BRADFORD have in press, and will shortly publish, A HISTORY OF NEW YORK, In two volumes, duodecimo. Price Three Dollars.
