As to Mr. Lincoln's name and fame and memory, — all is safe. His firmness, moderation, goodness of heart; his quaint humor, his perfect honesty and directness of purpose; his logic his modesty his sound judgment, and great wisdom; the contrast between his obscure beginnings and the greatness of his subsequent position and achievements; his tragic death, giving him almost the crown of martyrdom, elevate him to a place in history second to none other of ancient or modern times. His success in his great office, his hold upon the confidence and affections of his countrymen, we shall all say are only second to Washington's; we shall probably feel and think that they are not second even to his.
