The rebels were astonished, and the man who carried the mail-bags threw them down and held his arms above his head, in token of surrender. But the other, after regarding the officer for a moment, as if to make sure that it was a human being with whom he had to deal, dropped his oars, and before his captor was aware of his intention, drew a pistol and fired. Frank felt a sharp pain in his left shoulder, and the revolver which he held in that hand fell from his grasp. He had received his first wound, but although thoroughly frightened, he did not lose his presence of mind. If he had, he would soon have been recalled to a sense of his dangerous situation, for the rebel again cocked his revolver; but this time Frank fired first, and the rebel sank to the ground with a loud yell. In an instant Frank turned upon the other; but he appeared to be too much under the influence of fear to lend his comrade any assistance.

All thought of concealment was now out of the question. The rebels in the house had, of course, been alarmed, and Frank's only chance for escape with his prisoner and the mail was to reach the cutter as soon as possible, and pull off to the vessel. Hastily relieving the prisoner of his weapons, he directed him to pick up the mail and follow the course he pointed out.

The prisoner did as he was ordered; but they had not gone far when a loud yelling announced that the rebels in the house had been alarmed, and were in pursuit. Frank kept close behind his prisoner, who, through fear of the revolver, ran at a rapid rate, but they had further to run to reach the cutter than the guerrillas, and the latter gained rapidly. The prisoner, who was not long in discovering this, slackened his pace considerably, although he appeared to be doing his utmost. Frank, however, was not deceived. Thrusting his revolver into his pocket, he seized the rebel by the nape of the neck, and helped him over the ground in a manner more rapid than agreeable. Had the man been aware of the fact that his captor had but one arm that he could use, he might not have submitted so quietly as he did. Frank, whose whole mind was wrapped up in the idea of saving his prisoner and the mail, did not stop to think of this, but pushed his man ahead to such good advantage that they succeeded in reaching the cutter before their pursuers. He marched the rebel down the bank in the most lively manner, and tumbled him into the boat, where he was instantly seized and secured.

The sailors, who had heard the noise of the pursuit, and waited impatiently for the appearance of their officer, were all in their places, and as Frank sprang in, he shouted:

"Shove off—lively now, lads!"

The cutter was speedily pushed from the shore, and the oars got out and handled by twelve strong fellows, all good oarsmen.

"Let fall—give away together," again commanded Frank, who, in spite of the pain of his wound, began to chuckle over his good luck in securing the mail. "The rebs will give us a volley," he continued, "unless we get out of sight in the darkness before they reach the bank. So, pick her up, lads, and walk right away with her."

The sailors, understanding the order, and rejoicing in the escape of their young officer, whose safety and well-being they regarded as infinitely of more importance than their own, gave way manfully on the muffled oars, which made no sound as they bent beneath the sturdy strokes, and the cutter flew noiselessly through the water, The rebels reached the bank but a few moments after the cutter had left, but neither seeing nor hearing any thing of her, they contented themselves with uttering their yells, and firing a volley into the darkness in the direction they supposed the boat had gone.

But their attention was soon called to another quarter, for a bright flame shot up from the house. The boat's crew saw it, and could scarcely refrain hurrahing; but knowing that they were not yet out of range of the guerrillas' rifles, they gave vent to their jubilant feelings by redoubling their efforts at the oars.

"Mr. Nelson," whispered the coxswain, "may I be allowed to say that was well done, sir!"
