The first of these occurred as follows: After delivering messages and documents to Major Weightman, he proceeded to Baltimore, to deliver others to Mr. Thomas. While at the Fountain Hotel it chanced that his false moustache became loose, or somewhat disarranged. He stepped before a mirror, in the public reading-room, to readjust it, and, while doing so, observed a gentleman watching him very closely. Leaving that hotel instantly, he went to Barnum's, but was scarcely there before he noticed the same gentleman, who had watched him in the other hotel, again eyeing him closely. Soon the gentleman stepped up to him, and called him by his first name. The Colonel immediately recognized him as an old army friend, whom he had not seen for many years, and whom he had little thought to meet there, and under such circumstances. The gentleman was a Southerner; recognized, and entirely approved of the Colonel's new position as Ambassador Extraordinary between high contracting parties; and in a little while after they were drinking the health of each other, and confusion to their enemies. The Colonel at first feared that one of Baker's detectives had discovered his disguise while he was arranging his moustache, as before related, and felt not a little relieved when his observer turned out to be a friend instead of an enemy. He never again adjusted his false moustache in the reading-room of a hotel. The other incident occurred as follows: He had been to Washington, and was on his return to Richmond. Crossing the Potomac, at a point above the Great Falls, he was accosted by a man on the Virginia side, who wanted to know where he had come from, and where he was going? Colonel Killgore replied that he lived in Maryland, not far from the Falls, and was on his way to visit a friend on the Virginia side. Other conversation followed, until the Colonel thought his questioner was satisfied, though he meanwhile had fully made up his mind that his questioner was none other than one of General Baker's secret detectives. The Colonel finally bade his questioner good-bye, and started to leave, when his questioner cried out, "Stop! I believe you are a spy--you are my prisoner!"
