The steam rolled over the lower deck in thick clouds, rendering it impossible for him to go aft. There was now but one way to reach the cutter, and that was to jump overboard and swim to her. This order was promptly given, and as promptly obeyed by the men, who sprang into the water, one after another, followed by Frank, who, however, had lingered a moment to pull off his side-arms and coat, which would only impede his progress, and to secure his dispatches, which he tied to his waist with a strong cord he happened to have in his pocket.

But when he reached the stern of the boat, he found that this means of escape had been destroyed. A shell from the battery had struck the cutter, and her wreck, still hold by the rope with which she had been made fast, floated along with the steamer, which was slowly drifting toward the bank. Only one of his men was to be seen, and that was the coxswain, who was holding on to the wreck, awaiting the appearance of his officer. The others, giving up all hopes of escape, had doubtless turned toward the shore.

"Now, here's a job, sir," said the coxswain, apparently as unconcerned as if there had not been a rebel within a hundred miles. "Here is a job. What's to be done now, sir?"

Frank had just asked himself the same question. He could easily reach the shore, which was but a few yards distant, but there he would certainly be captured by the rebels, who were running along the bank, yelling like demons.

There was but one course he could pursue and save himself and dispatches, and that was to swim down the river and endeavor to pass the battery. In the darkness he might escape undiscovered.

"Bob, are you a good swimmer?" he asked, turning to the coxswain.

"Yes sir! can swim all day," was the reply.

"Then follow me as silently as possible, and we may yet escape."

As Frank spoke, he swam down the river with swift, noiseless strokes, anxious to get as far as possible from the boat before the fire, which now began to make rapid headway, should light up the river and discover them to the rebels. The latter had ceased firing, and were scattered along the bank, making prisoners of the transport's crew as fast as they touched the shore. When Frank had reached the place where the battery was stationed, he turned upon his back, and allowed himself to float along with the current, and, aided by the darkness and the smoke of the burning transport, which blew down the river, he and his companion passed the dangerous point undiscovered. Here Frank again struck out, his every movement followed by the coxswain, who was close behind him, and who floated through the water like a cork.

For nearly an hour they remained in the river, and it was not until the shouts of the rebels could be no longer heard, that Frank, feeling for the present safe from pursuit, swam to the shore and sat down to rest, and to determine upon their future movements.
