"There's something up," thought Webster, as he boarded the train. "Perhaps that fellow is on the look-out for new-comers like myself; but we'll see whether he is sharp enough to catch a weasel asleep."

For the first twenty miles after leaving the Tennessee river, the road lay through an uncultivated region of swamps and heavy timber. At every station along the route uniformed men, heavy guns, car-loads of muskets and ammunition were seen, indicating general and active preparations for war, while the secession flag was flying in the breeze, and the music of fife and drum was frequently borne to the ear. At Humboldt, where the train arrived at four o'clock in the afternoon, they were delayed for some time, and Webster improved the opportunity to look around him and to procure his dinner. The man with the broad-brimmed hat seated himself almost opposite Webster at table, who noticed that his restless, inquisitive eyes were kept busy scrutinizing every face that came within range of his vision. He did not address himself to any one during the progress of the repast, and after hurriedly satisfying his own appetite, he walked out upon the platform of the depot, where he stood intently watching the other passengers as they returned to the train.

Webster, as he crossed the platform, instinctively felt that those searching eyes were riveted upon him as if they would pierce him through, but he did not evince the slightest degree of trepidation or uneasiness under the ordeal. Assuming an air of quiet unconsciousness, he sauntered past the man without seeming to notice him, and entered the smoking-car, coolly lighted a cigar, drew a Nashville newspaper from his pocket, and settled himself to his reading. He saw no more of the mysterious stranger during the remainder of the journey, but on alighting from the train at the Memphis depot, the first object that met his gaze was the wearer of the broad-brimmed hat.

Arriving in Memphis at nine o'clock in the evening, Webster went directly to the Worsham House, where he intended to stay while in the city. While registering his name he observed a military officer in full uniform standing at his elbow, watching him closely as he wrote. Several other new arrivals placed their signatures after Webster, and he then noticed that the officer was engaged in making a copy of names and addresses on a piece of paper.

While watching this proceeding, his attention was distracted by some one hastily entering the hotel office. It was his mysterious fellow-traveler, who, stepping into the center of the room, glanced quickly around, apparently looking for some particular face. The search was evidently successful, for, walking up to one of the men who had just arrived on the train from the North, he tapped him on the shoulder and beckoned him.

After a few moments' conversation, during which the new-comer appeared to be both surprised and frightened, the two left the hotel together and walked up the street arm in arm.

Two citizens who were lounging near the door had been interested spectators of this incident, and Webster heard one of them inquire:

"What does that mean?"

"It means that the stranger is under arrest," replied his companion.

"Under arrest? And who is the man who arrested him?"
