"Goodbye, sir," said Harris, quietly. "Remember," said von Ludwig, "there is always a chance that you may escape. If it comes, make the most of it. Goodbye." He pressed Harris' hand and passed over the side of the vessel. As Frank and Jack shook hands with Harris, the latter squeezed Harris' hand affectionately. The latter smiled. "I had promised myself another bout with you some day," he said. "My only regret is that it is not possible now." A moment more Jack was in the motor boat and it moved away. Harris drew his revolvers and mounted guard over the companionway, the door of which now had begun to splinter. "An hour is what you needed," he said quietly. "You'll get it!" CHAPTER XXIX A CHAMPION PASSES Harris laid one of his revolvers on the deck, reached in his pocket and produced the six of diamonds. He looked at it closely in the half darkness and a smile passed over his face. "I suppose I'm a fool," he muttered to himself, "but someway I couldn't help it. I was afraid Jack would cut the low card. I wouldn't have done it for one of the others, but Jack, well, he's a boy after my own heart." Harris replaced the card in his pocket; then thought better of his action, drew it forth again and sent it spinning off across the sea. "There," he said quietly, "goes all evidence that I cheated." He picked up the revolver he had laid on the deck and moved a short distance from the companionway. There was an extra violent crash and it seemed that the door must burst open. "Another one like that will do the work," said Harris, calmly. He took up what he considered a strategic position and produced his watch. This he lay on the deck and sat down beside it. "May as well be comfortable," he remarked. Again there was a crash and the door of the companionway burst open. A German head appeared. "Crack!" Harris had fired without moving from his sitting posture. The German head disappeared and there was a cry of alarm from below. "One down, I guess," said Harris, quietly, to himself. For some moments there was silence, broken occasionally, however, by the dull sound of voices from below. "Talking it over, eh?" muttered Harris. "Well, I'll still be here when you try again." It was perhaps fifteen minutes later that a cap appeared in the opening. Again Harris fired. The cap did not disappear and Harris fired twice more quickly. The cap disappeared. "Guess I got another one," said Harris. Twice more within the next fifteen minutes this happened. "That should be four, if I have counted correctly," said Harris; "and I've still four cartridges left. I won't have to reload yet." He felt in his pocket and then uttered an exclamation of alarm. "No more bullets. I'll have to make these four count for the next two." Nothing appeared in the doorway again for ten minutes more and then Harris fired again. Fifteen minutes later the same thing happened and Harris, making sure that this was the last of the enemy, emptied his revolver at it.
