"Jest swim back quick," he commanded Sam, "and tell 'em we're all right. Tell 'em to come along. We'll hang to the buoy. Now, Tom, set to splashing with your legs. There'll be sharks about here, and they're extra fond of darkies." Tom paled for a moment under his dark skin and looked the reverse of comfortable. Then he laughed uproariously, shouted to Sam to hurry his departure, and promptly did as Jim had ordered. For it was as well to be cautious: both knew that sharks abounded in that corner of the Caribbean Sea, and some of the brutes might very well be in the vicinity. They kicked continuously, therefore, till the boat came up with a rush, and they and the injured man were lifted aboard. "Young man, you can jest give me a grip of yer hand," cried the skipper of the foundered vessel when all were safely in the boat, stretching across to the triumphant Jim. "I guessed when you came up alongside us on the ship, telling me that you had fixed matters for your sister, and were ready to help us out with the trouble those Spaniards were giving, that you had got stuff behind you--the right sort of stuff, too. Then you tackled the hounds in proper style, so that I knew I had a man with me; a man, siree, not jest a boy. But this last thing's better than all. Guess this gentleman owes you a life. Guess he'll be for ever in your debt. Young man, I'm pleased to have met you." It was a glowing tribute to our hero's courage, and he went crimson from the top of his dripping head to his stockinged toes as he listened to the words. Not that anyone could tell, for the gloom shrouded everything. However, Sadie, sitting beside him, clinging to his arm as if loath to part again with her protector, guessed his pleasure, while her own courageous little heart felt as if it would burst with pride. "I'm glad you did it, Jim," she whispered, "though I was terrified. And Tom and Sam were really brave; they are so devoted. Can you believe, I had the greatest difficulty to keep Ching with me? He hates swimming, as you know, but he was very nearly following." "Brave, honest fellows!" answered Jim with a gulp, for such devotion touched him. "They are, indeed, true friends to us." However, he had no time for further conversation; for now that the captain had given his decision on events so recent, the mate and crew of the boat were determined to make their own voices heard. "A right proper thing to have done: wish you was my own son," declared the former. "Shake, young man. It's a treat to meet one who's a true American." "One of the very right sort," growled Macdougal, still trembling with excitement. "See here, young feller, I've nigh lost a job through you. I was for kicking up a rumpus direct against the old man's orders. Chief, I'm main sorry for them words and looks; but there's a time when a man has to kick. I thought you was funking."
