In connection with these precautions, Colonel Stone, who commanded these forces, had kept himself informed about the disaffection in Baltimore, through the agency of the New York police department. The communication brought by young Mr. Seward contained besides notes from his father and General Scott, a short report from Colonel Stone, stating that there had arisen within the past few days imminent danger of violence to and the assassination of Mr. Lincoln in his passage through Baltimore, should the time of that passage be known. "All risk," he suggested, "might be easily avoided by a change in the traveling arrangements which would bring Mr. Lincoln and a portion of his party through Baltimore by a night train without previous notice." The seriousness of this information was doubled by the fact that Mr. Lincoln had, that same day, held an interview with a prominent Chicago detective who had been for some weeks employed by the president of the Philadelphia, Wilmington and Baltimore railway to investigate the danger to their property and trains from the Baltimore secessionists. The investigations of this detective, a Mr. Pinkerton, had been carried on without the knowledge of the New York detective, and he reported not identical, but almost similar, conditions of insurrectionary feeling and danger, and recommended the same precaution. Mr. Lincoln very earnestly debated the situation with his intimate personal friend, Hon. N.B. Judd of Chicago, perhaps the most active and influential member of his suite, who advised him to proceed to Washington that same evening on the eleven-o'clock train. "I cannot go to-night," replied Mr. Lincoln; "I have promised to raise the flag over Independence Hall to-morrow morning, and to visit the legislature at Harrisburg. Beyond that I have no engagements."
