Under this head, some years ago, there appeared, in the Southern Literary Messenger, an article which attracted very general attention, not less from the nature of its subject than from the peculiar manner in which it was handled. The editor introduces his readers to a certain Mr. Joseph Miller, who, it is hinted, is not merely a descendant of the illustrious Joe, of Jest-Book notoriety, but that identical individual in proper person. Upon this point, however, an air of uncertainty is thrown by means of an equivoque, maintained throughout the paper, in respect to Mr. Miller’s middle name. This equivoque is put into the mouth of Mr. M. himself. He gives his name, in the first instance, as Joseph A. Miller; but, in the course of conversation, shifts it to Joseph B., then to Joseph C., and so on through the whole alphabet, until he concludes by desiring a copy of the Magazine to be sent to his address as Joseph Z. Miller, Esquire. The object of his visit to the editor is to place in his hands the autographs of certain distinguished American _literati_. To these persons he had written rigmarole letters on various topics, and in all cases had been successful in eliciting a reply. The replies only (which it is scarcely necessary to say are all fictitious) are given in the Magazine, with a genuine autograph fac-simile appended, and are either burlesques of the supposed writer’s usual style, or rendered otherwise absurd by reference to the nonsensical questions imagined to have been propounded by Mr. Miller. The autographs thus given are twenty-six in all—corresponding to the twenty-six variations in the initial letter of the hoaxer’s middle name. With the public this article took amazingly well, and many of our principal papers were at the expense of re-printing it with the wood-cut autographs. Even those whose names had been introduced, and whose style had been burlesqued, took the joke, generally speaking, in good part. Some of them were at a loss what to make of the matter. Dr. W. E. Channing, of Boston, was at some trouble, it is said, in calling to mind whether he had or had not actually written to some Mr. Joseph Miller the letter attributed to him in the article. This letter was nothing more than what follows:— Boston, ——. Dear Sir, No such person as Philip Philpot has ever been in my employ as a coachman, or otherwise. The name is an odd one, and not likely to be forgotten. The man must have reference to some other Doctor Channing. It would be as well to question him closely. Respectfully yours, W. E. CHANNING. To Joseph X. Miller, Esq. The precise and brief sententiousness of the divine is here, it will be seen, very truly adopted, or “hit off.”
