“‘SIR--Circumstances not necessary for me to mention have rendered it expedient for me to inform you that you and I can no longer live in the same city. I will go further, and inform you that the time has come when you must answer for your dishonorable conduct. If you have any sense of honor left, you will readily accord to me the only satisfaction that I require. To be plain, I DEMAND that you name a time and place, without the limits of the State, when and where we can settle the matters of difference between us. My friend, Heartsell, is authorized to arrange preliminaries with you, or any friend you may choose to represent you. “‘Respectfully, “‘H. WALLINGFORD.’ “‘Mr. Heartsell,’ said I endeavoring to keep control of my feelings, ‘am I to understand this as a challenge to fight a duel?’ “‘The language used is very plain, sir, and such was the intention of my friend when he wrote it.’ “‘But I am opposed to the barbarous practice of dueling. The laws of the land prohibit it, public sentiment condemns it, and if I were not opposed to dueling, I could not fight Harry Wallingford. I would not hurt him for everything in the world; and why should he wish to take my life? I never injured him--I love his sister--she is my betrothed bride; and I would as soon think of killing myself as him.’ “‘That, sir, is a matter with which I have nothing to do; but you are mistaken when you say that public sentiment condemns the code of honor. I think the very reverse of that is true; because it is considered disgraceful to back down when challenged. The man who refuses to fight when challenged is branded as a coward, and honorable men shun him as such. Did public sentiment condemn Henry Clay, S. S. Prentiss, Albert S. Johnson, General Jackson and a thousand others I might name?’ “‘Yes, but public sentiment has undergone a great change since then; and our laws did not prohibit dueling then either.’ “‘Doctor Demar, can you name any one who has ever been punished for fighting a duel?’ “‘I am sorry to be compelled to answer in the negative.’ “‘I dare say you will admit that the reason is owing to public sentiment; but to the point--what answer do you wish me to convey to my friend Wallingford?’ “‘Give me one hour to consider on the matter, and to take the advice of my friends.’ “‘Certainly; but it will be considered dishonorable to mention the matter to more than one friend; and were you to do so, it might cause the civil authorities to get hold of the affair, which you know would serve to widen the breach between you and my friend Wallingford.’ “‘Mr. Heartsell, do you know what has caused Harry Wallingford to become offended with me?’ “‘Oh, yes, Doctor Demar; your little secret is out, and you must face the music.’ “‘What do you mean by my little secret being out?’
