of voice. None of them, strangely enough, wore a uniform, although they were all loyal Union soldiers belonging to the division of troops commanded by General O. M. Mitchell, then encamped on the banks of Duck River, only a couple of miles away. For the country was now engaged in the life-and-death struggle of the Civil War, when Northerner fought against Southerner—sometimes brother against brother—and no one could predict whether the result would be a divided or a reunited nation.

“My friends,” the speaker was solemnly saying, as a new flash from the darkened heavens lit up the landscape for a second, and showed how resolute were the lines of his face; “my friends, if you go into this scheme with me, you are taking your lives into your hands. It’s only fair that I should impress this upon you, and give any and all of you a chance to drop out.”

There was a quick, sharp clap of thunder, which was not loud enough, however, to drown the earnest protest of every listener. “We’re not cowards, Andrews!” “We’ll stick to you through thick and thin!” “Nobody’s going to draw back!” These were among the fervent answers which greeted the leader addressed as Andrews. The latter was evidently pleased, though by no means surprised. He was dealing with brave men, and he knew his audience.

“All the better, boys,” he went on, with a complacent ring in his soft but penetrating voice. “You see, this is the situation. The Confederates are concentrating at Corinth, Mississippi, and Generals Grant and Buell are advancing by different routes against them. Now, our own General Mitchell finds himself in a position to press into East Tennessee as far as possible, and he hopes soon to seize Chattanooga, after he has taken Huntsville, Alabama. But to do this he must cut off Chattanooga from all railroad communication to the south and east, and therefore all aid. In other words, we men are to enter the enemy’s country in disguise, capture a train on the Georgia State railroad, steam off with it, and burn the bridges leading in the direction of Chattanooga, on the northern end of the road. It is one of the most daring ideas ever conceived, and its execution will be full of difficulties. If we fail we shall be hanged as spies! If we succeed, there will be promotion and glory for all of us, and our names will go down into history.”

There was a murmur of encouragement from the men, as one said: “We must succeed, if only to save our necks.” The next moment the barking of a dog could be heard above the whistling of the wind.

“Be careful,” cried Andrews, warningly; “some one may be listening.”

Hardly had he spoken before two figures bounded from the encircling trees into the open space wherein stood the startled conspirators. While flashes of lightning played through the branches, and gave fitful illumination to the scene, the men saw revealed a lad of about fifteen or sixteen years of age, flushed and breathless, and at his heels a tiny Yorkshire terrier, bright of face, and with an inquiring glance that seemed to say: “What is all this fuss about?” As the animal danced around the boy it was evident that the latter was by no means frightened, or even surprised, by the strangeness of this meeting in the forest. His regular, handsome features and intelligent, sparkling gray eyes denoted excitement rather than fear. He sprang forward, and, pulling a letter from an inner pocket of his blue jacket, made straight for Andrews.

“Why, if it isn’t George Knight,” muttered one soldier, “and his chum, Waggie.”

The dog, hearing his own name, came up and fawned upon the man who had spoken, while the boy thrust into the hands of the leader the letter which he had so carefully guarded.

“This is from General Mitchell,” explained young Knight. “He said it was most urgent—and I was to fetch it to you as soon as possible.”

Andrews opened the letter, as he replied kindly to the lad: “You look out of breath, George. Did you have a hard time reaching here?”

“As Waggie and I were hurrying up the Shelbyville road in the darkness,” returned George Knight, “we ran into a company of Confederate guerrillas. They paid us the compliment of firing at us—and we had to run for our lives. But we gave the fellows the slip.”

Thereupon Waggie gave a growl. Andrews, who was about to read the letter from General Mitchell, assumed a listening attitude. So did every one else. Out on the highroad, not a hundred yards away, could be heard the tramping of horses. Involuntarily the men put their hands towards the pockets which contained their revolvers.

“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.
