Bang! Alfy felt a heavy blow on his head, which made the fire flash from his eyes, and nearly knocked him overboard; but, tingling with pain and indignation, he swept round the oar he held in his right hand, and struck the man sharply on the shoulder.

His assailant seized the oar, and a smart struggle ensued, in which the man's superior strength and position enabled him to be victorious. He wrested the oars from Alfy, and then, after cuffing him soundly, and calling him an "insolent young warmint," tied him tightly to the skiff with the boat-rope—which is commonly called the painter.

Alfy, smarting with the injustice of the attack, managed to administer a few wholesome kicks to his assailant during the struggle. Then a long, low whistle sounded, and the man hurried away, leaving the boy bound and aching in the boat.

The day was now fast wearing on, and the sun was beginning to sink in the heavens. As Alfy lay back in the boat his mind was racked with anxiety about the provisions, and his promises to take back food to the Island House. His sisters and Mansy might starve if he could not get the provisions to them. Then he shouted aloud to attract attention.

No answer came. His voice seemed borne back upon him as from an empty void. Again and again he called until he grew weary with shouting, and sickened with suspense and anxiety and disappointment. He seemed as far from his kind here as if he were alone in the deserts of Arabia.

Then he bethought him once more of self-help. "I wonder if I could free myself," he said. "I have got over several difficulties lately, perhaps I can get over this one also." He struggled upwards to a sitting position, and looked at his bonds. His wrists and ankles were tied pretty firmly, and one end of the rope was of course fastened to the boat.

"I suppose that rascal tied me up like this to give himself time to escape," said Alfy thoughtfully, as he looked down at the rope. "He thinks I know a lot about him, and will tell what I know, and he wants to get a good start. I wonder if I could undo these knots with my teeth? They crack nuts, why not untie knots? I will try."

"'I WONDER IF I COULD UNDO THESE KNOTS WITH MY TEETH? I WILL TRY.'"
