Jas. Shields, Esq.--Your note of to-day was handed me by Gen. Whiteside. In that note, you say you have been informed, through the medium of the editor of "The Journal," that I am the author of certain articles in that paper which you deem personally abusive of you; and, without stopping to inquire whether I really am the author, or to point out what is offensive in them, you demand an unqualified retraction of all that is offensive, and then proceed to hint at consequences. Now, sir, there is in this so much assumption of facts, and so much of menace as to consequences, that I cannot submit to answer that note any further than I have, and to add, that the consequence to which I suppose you allude would be matter of as great regret to me as it possibly could to you. Respectfully, A. Lincoln. In about an hour Gen. Whiteside called again with another note from Mr. Shields; but after conferring with Mr. Butler for a long time, say two or three hours, returned without presenting the note to Mr. Lincoln. This was in consequence of an assurance from Mr. Butler that Mr. Lincoln could not receive any communication from Mr. Shields, unless it were a withdrawal of his first note, or a challenge. Mr. Butler further stated to Gen. Whiteside, that, on the withdrawal of the first note, and a proper and gentlemanly request for an explanation, he had no doubt one would be given. Gen. Whiteside admitted that that was the course Mr. Shields ought to pursue, but deplored that his furious and intractable temper prevented his having any influence with him to that end. Gen. W. then requested us to wait with him until Monday morning, that he might endeavor to bring Mr. Shields to reason. On Monday morning he called and presented Mr. Lincoln the same note as, Mr. Butler says, he had brought on Saturday evening. It was as follows:-- Tremont, Sept. 17, 1842. A. Lincoln, Esq.--In your reply to my note of this date, you intimate that I assume facts and menace consequences, and that you cannot submit to answer it further. As now, sir, you desire it, I will be a little more particular. The editor of "The Sangamon Journal" gave me to understand that you are the author of an article which appeared, I think, in that paper of the 2d September inst., headed "The Lost Townships," and signed Rebecca or 'Becca. I would therefore take the liberty of asking whether you are the author of said article, or any other over the same signature which has appeared in any of the late numbers of that paper. If so, I repeat my request of an absolute retraction of all offensive allusion contained therein in relation to my private character and standing. If you are not the author of any of the articles, your denial will be sufficient. I will say further, it is not my intention to menace, but to do myself justice. Your ob't serv't, [Copy.] Jas. Shields.
