How hurtful the insinuations, and even direct charges, of the day, made by these men against President Lincoln, must have been to his honest, sincere, and sensitive nature, can scarcely be conceived by those who did not know him; while, on the other hand, the reckless impatience of some of his friends for "immediate and universal Emancipation," and their complaints at his slow progress toward that goal of their hopes, must have been equally trying. True to himself, however, and to the wise conservative course which he had marked out, and, thus far, followed, President Lincoln hastened to disavow Hunter's action in the premises, by a Proclamation, heretofore given, declaring that no person had been authorized by the United States Government to declare the Slaves of any State, Free; that Hunter's action in this respect was void; that, as Commander-in-chief he reserved solely to himself, the questions, first, as to whether he had the power to declare the Slaves of any State or States, Free, and, second, whether the time and necessity for the exercise of such supposed power had arrived. And then, as we may remember, he proceeded to cite the adoption, by overwhelming majorities in Congress, of the Joint Resolution offering pecuniary aid from the National Government to "any State which may adopt a gradual abolishment of Slavery;" and to make a most earnest appeal, for support, to the Border-States and to their people, as being "the most interested in the subject matter." In his Special Message to Congress,--[Of March 6, 1862.]--recommending the passage of that Joint Resolution, he had plainly and emphatically declared himself against sudden Emancipation of Slaves. He had therein distinctly said: "In my judgment, gradual, and not immediate, Emancipation, is better for all." And now, in this second appeal of his to the Border-States men, to patriotically close with the proposal embraced in that. Resolution, he said: "The changes it contemplates would come gently as the dews of Heaven, not rending or wrecking anything. Will you not embrace it? So much good has not been done, by one effort, in all past time, as, in the providence of God, it is now your high privilege to do! May the vast future not have to lament that you have neglected it!" [The following letter, from Sumner, shows the impatience of some of the President's friends, the confidence he inspired in others nearer in his counsels, and how entirely, at this time, his mind was absorbed in his project for gradual and compensated Emancipation.] "SENATE CHAMBER, June 5, 1862.
