"And I ain't worryin'," came a well-known voice through the darkness. "I comed along here jest to see what's happenin'. Is Massa Jim right and well?"
A growl burst from Tom's lips as he recognized the voice, and at once he turned a pair of blazing eyes upon the culprit who had dared to follow him.
"Dat yo, Sam?" he demanded. "Den what fo yo dare to leave de missie? Yo get back right now, or by de poker, me knock you into twenty cocked hat! What fo yo jump overboard and risk gettin' drowned?"
The question brought a gurgle from the jolly little Sam. He laughed outright beneath the nose of the irate Tom, and, reaching the buoy, clung to it for a moment or so before he deigned to reply.
"Yo's one great big donkey, yo am, Tom," he roared, shaking with laughter. "Yo tinks yo de only man allowed to jump into de water; but dat not so. De young massa place yo in charge of de missie, and yo no right to leave. Me knows dat; me comes along right out here to haul yo back. Yo one great big blackguard."
To the astonishment of Tom and Jim the little fellow burst into violent sobs, though his words had conveyed anything but an idea of sorrow. Sam shook from the top of his woolly head to his shoeless toes, and set the buoy rocking. Big tears coursed down his cheeks, though the water dripping from his hair almost cloaked them, and when he tried to speak again he gulped at the words and failed to express them. It was, in fact, a strange if comical procedure, and for the moment Jim's muddled condition did not help him to arrive at the meaning. But he grasped the truth a moment later, for Tom helped him.
"Yo—yo one little rascal, yo!" he heard the huge fellow exclaim, though there was no anger in his voice, no resentment for the words which Sam had hurled at him. Rather there was a strange trembling which denoted friendly feeling, accompanied by a sudden gripping of hands between the two darkies which seemed to say that they were perfectly agreed. Then Jim gathered the full meaning of Sam's tears, of Tom's magnanimous action. It was joy for his, Jim's, safety that had set Sam howling, and the tears coursing down his cheeks. It was that same feeling which induced Tom to overlook the high-flown language of his small brother and grip his hand so warmly.
"You're just two great grown-up babies," he laughed across at them. "You seem to imagine that no one can do anything without you, that I'm like a piece of china, liable to break on the smallest occasion. See here, Tom and Sam, shake hands. Guess you're both of you white right away through from head to toe. I owe you both a heap for coming out after me; but mind what I've said—I ain't a piece of china. Guess I'm old enough and ugly enough to look after myself."
Tom grinned back at his young master and hung to the buoy for a while, still clinging to the hand he had offered. Then he dropped it, moved to the farther side, as if to place himself in a position of safety, and presently made his reply.
"Sah," he said, "p'raps you old enough, as yo say, p'raps no. Ugly 'nough: yes, I tink so. Yo's ugly 'nough to do one ob de stupidest tings as ever I seed. What fo yo jump into de sea like dat and swim toward a ship dat was sinking? S'pose she drag yo down? S'pose yo neber come up agin. Who den take care of missie?"
