"If it is the same to you, we would rather remain where we are," Tom answered promptly. "You see, we are not used to this kind of thing, and that stuffy hold makes us feel ill. We will ask you to lend us a couple of blankets in which to wrap ourselves."
"You shall have them, but you cannot sleep here, for the look-out man must stand in this position; but you can go farther along the deck, if you like. Come with me now, and I shall give you what you have asked for."
Ten minutes later Jim and his friend were wrapped from head to foot in thick blankets, and had taken their places close to the bulwark on one side, and about the centre of the vessel. As they did so one of the crew passed them and went to take his station forward, while the remainder proceeded aft, and throwing themselves down upon the deck, prepared to sleep. Two hours passed without incident, Tom's heavy breathing telling clearly that he was asleep. Then Jim, whose eyes had been wide open all the time, touched him gently with his foot, and had the satisfaction of seeing that he had awakened his companion. Then curling himself in his blanket, he closed his eyes. He could not sleep, however, for, though he was tired out with the long day of excitement, his novel position, and the thought that danger threatened them, kept him wide awake. He was, therefore, fully prepared when Tom stealthily stretched out an arm and tugged at his blanket, and at once sat up with his back against the bulwark. Once more it was time for his companion's watch, and Jim, who was now feeling decidedly drowsy, awoke him and lay down again upon the deck. A few minutes later he was fast asleep, and remained so for a considerable period. But a shout from Tom suddenly roused him, and, starting up, he saw that a struggle was taking place within a few feet of him. Dawn was just breaking, and the light enabled him to discover the fact that his companion was clasped in the arms of two of the natives, who were hustling him towards the bulwarks, and evidently endeavouring to throw him overboard.
Springing to his feet, Jim leapt across the deck at one bound, and sent his fist crashing into the face of one of Tom's opponents. Then, with a shout, he clasped the other by the neck, and, tearing him from his hold, sent him reeling across the deck.
"What has happened, Tom?" he asked. "What made them attack you?"
"I can't say," was the breathless answer; "but I deserved to be thrown overboard, for I believe I had fallen asleep. At any rate, they were upon me before I was aware of it, and, while one held me by the shoulders and placed a hand firmly over my mouth, the other caught me by the legs, and hustled me to the side. I fought like a cat, and managed to free my mouth. But you saved my life, old chap."
"Look out! They are preparing to rush again," cried Jim, in a warning voice. "I suppose we must make a fight for it."
As they were talking, the two men who had attacked Tom had picked themselves up, and had retired to their comrades, who stood close to the helm. That they were disconcerted by the sudden resistance was evident, but, seeing only two unarmed young fellows, they forgot their fear, and at once prepared to renew the combat. Snatching arms from a pile which lay beside them on the deck, they shouted to their comrades to join in the struggle, and then came rushing towards Jim and Tom at their fastest pace.
It was a critical moment, and might well have unnerved the bravest of men. Indeed, Tom was so shaken by the narrow escape he had had, that, for a second or two, he did nothing but stare at his opponents, as if fascinated. Jim, however, was fully alive to the danger, and promptly took measures to protect himself. Without taking his eyes from the natives he felt for and grasped the butt of a revolver, and, as they approached, presented it at their heads, hesitating to press the trigger in the hope that a sight of the weapon would overawe them. But they were maddened with rage, and, with shrill cries, came on boldly, waving their swords above their heads.
Crack! Jim pressed the trigger ever so gently, and, to his astonishment, the report had scarcely rung out upon the air when the leading man suddenly tossed his weapon above his head and fell to the deck with a crash. A second later, the native who followed him tripped over his body, and came sprawling upon all fours, where he lay, stunned by the fall.
