Very respectfully,

(Signed) JOHN A. CAMPBELL,

Associate Justice of the Supreme Court, United States.

Hon. William H. Seward, Secretary of State.

Judge Campbell to Mr. Secretary Seward.

Washington, April 20, 1861.

Sir: I inclose you a letter, corresponding very nearly with one I addressed to you one week ago (April 13th), to which I have not had any reply. The letter is simply one of inquiry in reference to facts concerning which, I think, I am entitled to an explanation. I have not adopted any opinion in reference to them which may not be modified by explanation; nor have I affirmed in that letter, nor do I in this, any conclusion of my own unfavorable to your integrity in the whole transaction. All that I have said and mean to say is, that an explanation is due from you to myself. I will not say what I shall do in case this request is not complied with, but I am justified in saying that I shall feel at liberty to place these letters before any person who is entitled to ask an explanation of myself.

Very respectfully,

JOHN A. CAMPBELL,

Associate Justice of the Supreme Court, United States.
