“The guerrillas!” muttered the boy, as Andrews gave him a questioning look.

“How many are there of them?” asked the leader.

“Hard to tell in the dark,” answered George. “I think there were a dozen or so.”

“Oh, if that’s all, let’s give ’em a scare, boys!” laughed Andrews. Suiting the action to his words, he pulled out a pistol from his hip pocket, and fired it in the direction of the highroad. His companions, nothing loath, quickly followed his example. George and his canine chum looked on expectantly, as if regretting that neither of them possessed a weapon. Now there came the clatter of hoofs, like a stampede, and the guerrillas seemed to be engaged in a wild scramble to get away. They were an intrepid party, without doubt, but the sudden volley from the mysterious and darkened recesses of the woods (which might come, for all the Southerners knew, from a whole regiment of troops) demoralized them. In another instant they were scampering off, and the sound of the horses on the road was soon lost in the distance.

Andrews replaced his revolver, with a little chuckle of amusement.

“They are a daring lot to venture so near our army,” he said. Then he began to read the letter, with the aid of a dark lantern provided by one of his companions.

While he is engaged in this occupation let us ask two questions. Who is Andrews, and who is George Knight? James Andrews, though a Virginian by birth, has lived in the mountains of Kentucky for many years, and is now a spy of the Union army, in the employ of General Buell. The war is only fairly begun, but already more than once has the spy courted death by penetrating into the lines of the Confederacy, in the guise of a merchant, and bringing back to the Northern forces much valuable information. He is a man of fine education and polished manners, despite his life in the wilds, and is tall, aristocratic-looking, and full of a quiet courage which, in his own dangerous profession, answers far better than the greatest impetuosity. He has plenty of daring, but it is a daring tempered with prudence. Although he has masqueraded among the enemy at times when the slightest slip of the tongue might have betrayed him, he has thus far returned to the Union lines in safety. How long, some of his friends ask anxiously, will he be able to continue in so perilous an enterprise? Yet here he is, planning, with the consent of General Mitchell, a scheme bolder than anything yet dreamed of in the annals of the war.

And what of George Knight? He is an active, healthy-minded drummer boy belonging to one of the Ohio regiments in General Mitchell’s division. His mother had died in his infancy. At the outbreak of the war, a year before the opening of our story, he was living in Cincinnati with his father. The latter suddenly gave up a prosperous law practice to go to the help of the North, secured a commission as a captain of volunteers, went to the front, and was either captured or killed by the Confederates. Since the preceding Christmas nothing had been heard of him. George, with an aching heart, stayed at home with an uncle, and chafed grievously as he saw company after company of militia pass through his native town on the way to the South. Where was his father? This he asked himself twenty times a day. And must he, the son, stand idly by whilst thousands of the flower of the land were rushing forward to fight on one side or the other in the great conflict? “I must enlist!” George had cried, more than once. “Pshaw!” replied his uncle; “you are too young—a mere child.” But one fine day George Knight had himself enrolled as a drummer boy in a regiment then being recruited in Cincinnati, and, as his uncle had a large family of his own, with no very strong affection to spare for his nephew, there was not as much objection as might have been expected. So the lad went to the war. He had now become a particular protégé of General Mitchell, who had taken him into his own service as an assistant secretary—a position in which George had already shown much natural cleverness.

After reading the letter just brought to him, Andrews tears it into a hundred little pieces which he scatters to the winds.

“What’s the matter?” ask several of the men, as they crowd around him.
