Mr. Lincoln left Springfield on February 11th, in company with his wife and three sons, his brother-in-law, Dr. W. S. Wallace; David Davis, Norman B. Judd, Elmer E. Elsworth, Ward H. Lamon, Colonel E. V. Sunder of the United States Army, and the President’s two secretaries. GOOD-BYE TO THE OLD FOLK. Early in February, before leaving for Washington, Mr. Lincoln slipped away from Springfield and paid a visit to his aged step-mother in Coles county. He also paid a visit to the unmarked grave of his father and ordered a suitable stone to mark the spot. Before leaving Springfield, he made an address to his fellow-townsmen, in which he displayed sincere sorrow at parting from them. “Friends,” he said, “no one who has never been placed in a like position can understand my feelings at this hour, nor the oppressive sadness I feel at this parting. For more than a quarter of a century I have lived among you, and during all that time I have received nothing but kindness at your hands. Here I have lived from my youth until now I am an old man. Here the most sacred ties of earth were assumed. Here all my children were born, and here one of them lies buried. “To you, dear friends, I owe all that I have, all that I am. All the strange, checkered past seems to crowd now upon my mind. To-day I leave you. I go to assume a task more difficult than that which devolved upon Washington. Unless the great God who assisted him shall be with and aid me, I must fail; but if the same omniscient mind and almighty arm that directed and protected him shall guide and support me, I shall not fail--I shall succeed. Let us all pray that the God of our fathers may not forsake us now. “To Him I commend you all. Permit me to ask that with equal sincerity and faith you will invoke His wisdom and guidance for me. With these words I must leave you, for how long I know not. Friends, one and all, I must now bid you an affectionate farewell.” The journey from Springfield to Philadelphia was a continuous ovation for Mr. Lincoln. Crowds assembled to meet him at the various places along the way, and he made them short speeches, full of humor and good feeling. At Harrisburg, Pa., the party was met by Allan Pinkerton, who knew of the plot in Baltimore to take the life of Mr. Lincoln. THE “SECRET PASSAGE” TO WASHINGTON. Throughout his entire life, Abraham Lincoln’s physical courage was as great and superb as his moral courage. When Mr. Pinkerton and Mr. Judd urged the President-elect to leave for Washington that night, he positively refused to do it. He said he had made an engagement to assist at a flag raising in the forenoon of the next day and to show himself to the people of Harrisburg in the afternoon, and that he intended to keep both engagements.
