In a very short time General Whiteside called with a note from Mr. Shields, designating General Whiteside as his friend, to which Mr. Lincoln instantly replied designating me as his. On meeting General Whiteside, he proposed that we should pledge our honor to each other that we would endeavor to settle the matter amicably; to which I agreed, and stated to him the only conditions on which it could be settled; viz., the withdrawal of Mr. Shields's first note, which he appeared to think reasonable, and regretted that the note had been written, saying however, that he had endeavored to prevail on Mr. Shields to write a milder one, but had not succeeded. He added, too, that I must promise not to mention it, as he would not dare to let Mr. Shields know that he was negotiating peace; for, said he, "He would challenge me next, and as soon cut my throat as not." Not willing that he should suppose my principal less dangerous than his own, I promised not to mention our pacific intentions to Mr. Lincoln or any other person; and we started for Springfield forthwith.

We all, except Mr. Shields, arrived in Springfield late at night on Monday. We discovered that the affair had, somehow, got great publicity in Springfield, and that an arrest was probable. To prevent this, it was agreed by Mr. Lincoln and myself that he should leave early on Tuesday morning. Accordingly, he prepared the following instructions for my guide, on a suggestion from Mr. Butler that he had reason to believe that an attempt would be made by the opposite party to have the matter accommodated:

In case Whiteside shall signify a wish to adjust this affair without further difficulty, let him know that, if the present papers be withdrawn, and a note from Mr. Shields asking to know if I am the author of the articles of which he complains, and asking that I shall make him gentlemanly satisfaction if I am the author, and this without menace or dictation as to what that satisfaction shall be, a pledge is made that the following answer shall be given:

"I did write the 'Lost Township' letter which appeared in the Journal of the 2d inst., but had no participation in any form in any other article alluding to you. I wrote that wholly for political effect. I had no intention of injuring your personal or private character, or standing as a man or a gentleman; and I did not then think, and do not now think, that that article could produce, or has produced, that effect against you; and had I anticipated such an effect, I would have forborne to write it. And I will add, that your conduct towards me, so far as I knew, had always been gentlemanly, and that I had no personal pique against you, and no cause for any."

If this should be done, I leave it with you to manage what shall and what shall not be published.

If nothing like this is done, the preliminaries of the fight are to be:

1st. Weapons:—Cavalry broadswords of the largest size, precisely equal in all respects, and such as now used by the cavalry company at Jacksonville.

2d. Position:—A plank ten feet long, and from nine to twelve inches broad, to be firmly fixed on edge on the ground as the lines between us, which neither is to pass his foot over upon forfeit of his life. Next, a line drawn on the ground on either side of said plank and parallel with it, each at the distance of the whole length of the sword and three feet additional from the plank; and the passing of his own such line by either party during the fight shall be deemed a surrender of the contest.

3d. Time:—On Thursday evening at five o'clock, if you can get it so; but in no case to be at a greater distance of time than Friday evening at 5 o'clock.

4th. Place:—Within three miles of Alton, on the opposite side of the river, the particular spot to be agreed on by you.
