In spite of Archie's dangerous situation, which had tried his nerves severely, he listened to every word that was uttered, and even became interested in what the rebels were saying. Now and then he was called to a sense of his situation by the movements of the horse, which, being restive, came very near stepping on him as he pranced about.

Damon had been gone about half an hour, and the colonel had just commenced explaining to the man who had brought the mail the manner in which the capture of the Boxer was to be effected, when suddenly the report of a pistol startled every one on the portico. A moment afterward came another, which was followed by a yell of agony.

"What's that?" exclaimed the colonel, springing from his chair in alarm. "Are we attacked? Get out there, every mother's son of you!" he continued, as the men, having been aroused by the noise, came pouring out of the rooms in which they were quartered. "Every man able to draw a saber get out there! Run for the river! That's where the reports sounded, and if there are any boats there capture them. That will keep the Yankees on shore, and we can hunt them up at our leisure!"

The men ran out of the house and started for the river at the top of their speed, at the same time yelling with all the strength of their lungs, while the colonel and his officers ran into their room, and hastily seizing such weapons as came first to their hands, followed after. To describe Archie's feelings, as he lay there behind that bush and listened to the sounds of pursuit, were impossible. The noise the rebels made seemed to bewilder him completely, for he lay on the ground several moments, it seemed to him, without the power to move hand or foot.

Suddenly the thought struck him that now was the time to accomplish the object of the expedition. The house was deserted, and the yells, which grew fainter and fainter, told him that the rebels were getting further away. Yes, it was now or never. In an instant, Archie's courage and power of action returned. Springing to his feet, he ran to the end of the portico, on which were piled several bales of hay and bundles of fodder, which the rebels no doubt intended for their horses. But Archie determined that they should be put to a different use, for he quickly drew from his pocket two large bottles filled with coal oil, which he threw over the hay. He then applied a match, and in an instant it was in a blaze. He waited a moment to see it fairly started, and then sprang off the portico. As he passed the door, he heard an ejaculation of surprise, followed by the report of a pistol, and the noise of a bullet as it whizzed past his head. It frightened him, and at the same time acted upon him as the crack of a whip does upon a spirited horse; for when the rebel who fired the shot had reached the portico, Archie had disappeared in the darkness.

CHAPTER IV.

A Mark for the Union.

et us now return to Frank, whom we left setting out for the house, after having given Archie emphatic instructions to remain behind the tree until his return. He did not feel at all at his ease after he had left his cousin, for he might have stationed him in the most dangerous place that could have been found; and what if Archie should be discovered and captured? He was well enough acquainted with his cousin's disposition to know that he would not surrender without a fight; but what could he do when opposed by a regiment of veteran rebels? Frank thought not of his own peril, for that was something he had fully expected to encounter before he started. This was not the first time he had voluntarily placed himself in danger; but with Archie the case was different; and Frank was several times on the point of returning to his cousin and making use of his authority, as commander of the expedition, to send him back to the boat. By the time these thoughts had passed through his mind, he had reached a log-cabin which stood at a little distance from the house; and as he halted behind it, to shelter himself from the storm, still debating upon the course he ought to pursue in regard to Archie, some one inside the cabin commenced singing—
"I'll lay ten dollars down
And chuck 'em up one by one!"
If there was any more of the song, the rebel evidently did not know it, for he kept singing these two lines over and over, now and then varying the monotony of the performance by whistling. Frank stood for some moments listening to him, and finally began moving cautiously around the cabin, to find some opening through which he could look and see what was going on inside. He presently discovered a hole between the logs, and, upon looking in, saw a man seated on the floor before a fire-place, in which burned some pine knots, engaged in whittling out an oar with his bowie-knife. On the floor near him lay one evidently just finished. At the opposite side of the room stood a bag, from the mouth of which peeped several letters.

A thought struck Frank—which would be of the most benefit, to burn the house or to capture the mail, which might contain information of the greatest importance? Undoubtedly the latter would be of the most consequence. Then he debated long and earnestly upon the chances of escaping with the mail, should he attempt its capture. The man who had charge of it was a most powerful-looking fellow, who knowing the importance of his trust, and the certainty of receiving prompt and effective assistance from his comrades, would, no doubt, fight most desperately, unless he could be taken at disadvantage and secured before he had time to think of resistance. Besides, the cabin was scarcely fifty feet distant from the house, which Frank knew was filled with men, for he could hear them walking about the rooms and talking to each other. The least unusual noise would certainly alarm them, in which case escape would be entirely out of the question Frank, we say, thought over all these things, and finally coming to the conclusion that it would be worse than useless to attempt the capture of the mail, turned his attention to the house. How was he to set fire to it?
