It began amid the rockings of rebellion. A servile predecessor, deplorably weak, if not criminal, had permitted treason to be freely mouthed in the national capitol, treasonable action to be taken by State authorities, and armed treason to resist and defy federal authority, and environ with bristling works the forts and flag of the Union. At such a juncture, Mr. Lincoln, then barely escaping assassination, was inaugurated. As was right, he made all proper efforts for conciliation, tendered the olive-branch, proposed such changes as existing laws, and even of the Constitution, as should secure Southern rights from the adverse legislation of a sectional majority. All was refused, and traitors said, "We will not live with you. Though you sign a blank sheet and leave us to fill it with our own conditions, we will not abide with you." Refusing peace, war was commenced, not by the President, but by secessionists. War has been waged on a scale of astounding vastness for four years, and Mr. Lincoln falls as the day of victory dawns. His claim to the character of a great statesman is to be estimated in view of the fiery ordeal which tried him, and not by the gauge of peaceful days. In addition to the most powerful armed rebellion ever organized, he was confronted by a skillful, able, persistent, well compacted partisan opposition. He was to harmonize sectional feelings as antagonistic as Massachusetts and Kentucky, and to rally to one flag generals as widely apart in sentiment and policy as Phelps and Fitz John Porter. That under such difficulties he sometimes erred in judgment and occasionally failed in execution, is not strange, for he was a man, but that he erred so seldom, and that he so admirably retrieved his mistakes, shows that he was more by far than an ordinary man; more by far than an average statesman. Standing where we do today, we feel that he was divinely appointed for the crisis; that he was chosen to be the Moses of our pilgrimage, albeit, he was to die at Pisgah and be buried against Beth-Peor, while a Joshua should be commissioned to lead us into the land of promise. In studying the administration of these four eventful years, it seems to me there were four grand landmarks of principle governing him, ever visible to the eye of the President, by which he steadily made his way. I. THE UNION IS INCAPABLE OF DIVISION.
