At Jack's cry of amazement Frank slowly opened his eyes. His constitution was not nearly as strong, as that of his huge friend. He was almost unconscious as the result of his terrible fall. But he recognized his chum in an instant, smiled feebly, and then his muscles relaxed. He lay a dead weight in Jack's arms. Quickly the lad looked round for some sign of a vessel, or a piece of wreckage to which to cling until he could be picked up. There was none, so still carrying his friend he struck out in the direction of the nearest ship, which could even now be seen approaching. The sounds of battle still continued, but they gradually grew less as the Austrian fleet, or what was left of it, retired to the protection of its land batteries. Four warships sent to the bottom of the sea, three submarines missing, and undoubtedly gone forever, and a half score of torpedo boats sunk, was the Austrian loss. The French had lost two battleships, a submarine and three torpedo boats. The heaviest losses sustained by both sides had been to the air fleets. Now the approaching vessel drew closer to Jack, and he at length realized that he had been seen. A small boat put off to him. Strong arms gripped him and pulled him and Frank into the boat, and a hearty voice exclaimed in English: "By Jove! They're English! Now, how do you suppose they got here?" Jack was conscious of a pleasant sensation at hearing his native tongue spoken thus, but he was too exhausted to take much interest in it then. He fell back unconscious. But, if the lad was surprised at thus being addressed in English, there was still a greater surprise and joy in store for him--and for Frank. When Jack reopened his eyes, he lay in a small but well-furnished cabin. Frank lay near him. He already had returned to consciousness, and even now was glancing curiously about. He glanced at Jack as the latter opened his eyes. "By George!" he ejaculated. "I was afraid you were done for, you lay there so quietly. How did I come here?" "Why," said Jack, "you toppled into the sea right beside me, and I grabbed you and held on until we were picked up." "Then," cried Frank excitedly, "you were aboard the first plane that dived into the dirigible?" "I was there," replied Jack briefly. "By Jove! I thought so. It looked like some your doings. And, if you hadn't thought of that method of attack, the whole French fleet probably would have been sunk!" "Well, somebody had to do it," said Jack modestly. "I notice you weren't far behind yourself." "Well," said Frank quietly, "I am glad we accomplished the task successfully. Where are we now?" "I don't know exactly," replied Jack. "But, as we were picked up, I heard someone talking in English. I believe that we are on an English ship that happened on the scene just in time to get into the battle." "Well--" began Frank, and stopped suddenly, staring open-mouthed at a figure now framed in the doorway of the little cabin.
