There is an aspect of Mr. Lincoln's career, which must attract general attention and command universal sympathy. His loneliness in his office and in the performance of his duties is deeply pathetic. It is true that Congress accepted and endorsed his measures as they were presented from time to time, but there were bitter complaints on account of his delays on the slavery question, and not infrequently doubts were expressed as to the sincerity of his avowed opinions. There were little intrigues in Congress, and personal aspirations in the Cabinet in regard to the succession. Of the commanders of the Army of the Potomac from McDowell to Meade, each and all had failed to win victories, or they had failed to secure the reasonable advantages of victories won. There were divisions in the Cabinet which were aggravated by personal rivalries. On one occasion, leading Republican members of Congress engaged in a movement for a change in the Cabinet; a movement which was without a precedent and wholly destitute of justification under our system of government. His want of faith in his Cabinet was shown in his preliminary statement when he proceeded to read the Proclamation of Emancipation. Mr. Lincoln was then about to take the most important step ever taken by a President of the United States and yet he informed the men, the only men whose opinions he could command by virtue of his office that the main question was not open for discussion; that the question had been by him already decided, and that suggestions from them would be received only in reference to the formalities of the document. It may be the truth, and our estimation of Mr. Lincoln would not be lowered, if, indeed, it were shown to be the truth, that he chose to act upon his own judgment in a matter of the supremest gravity, and in which, from the nature of the case, the sole responsibility was upon him. On the great question of the abolition of slavery his mind reached a definite conclusion, a conclusion on which he could act, but neither too early nor too late. The Proclamation was issued at a moment when the exigencies of the war justified its issue as a military necessity, and when, as a concurrent fact, the public mind was first prepared to receive it, and to give to the measure the requisite support. Mr. Lincoln prepared the way for the reorganization of the government. Under him the old order of things was overthrown and the introduction of a new order became possible. Through his agency the Constitution of the United States has been brought into harmony with the Declaration of Independence. The system of slavery has perished, the institutions of the country have been reconciled to the principles of freedom, and in these changes we have additional guarantees for the perpetuity of the Union.
