You will next observe the address of this letter. It is “To His Excellency, Jefferson Davis, President of the Confederation of States.” Bestowing upon this Pretender the title of “His Excellency,” the author certainly exhibits a courtesy--at least in form--which usage does not allow the President of the United States. It is well known, that, at the organization of the Government, the title of “Excellency,” together with all other titles, was, after debate, carefully rejected for our Chief Magistrate; but the author of this treasonable letter will not deny anything to the Chief of the Rebellion. His profusion appears at once, and his first words become a confession. Not by titles of courtesy do loyal Senators address a traitor. There has been a King of England who on one occasion was called only Charles Stuart, and there has been a King of France who on one occasion was called only Louis Capet; and these great instances show how even the loftiest and most established titles are refused, where treason is in question. Titles are sometimes insincere; but a title voluntarily bestowed testifies at least to the professions of him who bestows it. It is a token of respect, and an invitation to good-will, proceeding directly from the author. And in this spirit was this letter begun. Not content with bestowing upon this Pretender a title of courtesy denied to our own President, the author proceeds to bestow upon him a further title of office and of power. He addresses him as “President of the Confederation of States,”--meaning the very States then engaged in levying war upon the National Government. So far as this author can go, just to the extent of his authority, the Pretender is recognized as President, and the Rebel States are described by the very title which, in defiance of the National Government, they assume. Our own Government steadfastly refuses this recognition. Foreign nations thus far follow substantially the policy of our own Government; but the author of this letter, at the time Senator, makes haste to offer recognition. Perhaps this double criticism on the address of the letter may seem unimportant. It might be so, if the address had been used in conversation or debate, although then it would be tolerable only if used in derision. But it becomes important, when used directly to the Pretender himself; for then it signifies respect and recognition, while it discloses the mood of the author. Look next at the contents, or the letter itself, and all that is implied in the address you will find painfully verified. The disloyalty which crops out in titles of courtesy and recognition becomes full-blown in the letter itself, whether we regard its general character or its special import; and I shall now consider these in their order.
