"No; I won't do that now, either," declared Charlie, sternly setting his jaw. "I'll put you in irons, rather—and keep you on bread and water—till you answer my questions."

"You will, eh?" retorted the youth, flashing fire from his fine eyes. And as he spoke, quick as thought, he leaped up on to the gunwale, and, without hesitation, dived into the great glassy rollers.

But Charlie was quick too. Like a flash, he grabbed one of the boy's ankles, so that the beautiful dive was spoiled; and there was the boy, hanging by an imprisoned leg over the ship's side, a helpless captive—his arms in the water and his leg struggling vainly to get free. But he might as well have struggled against the grip of Hercules. In another moment Charlie had him hauled aboard again, his eyes full of tears of boyish rage and humiliation.

"You young fool!" exclaimed Charlie. "The water round here is thick with sharks; you wouldn't have gone fifty yards without one of them getting you." ...

"Sharks!" gasped out the boy, contemptuously. "I know more about sharks than you do."

"You seem to know a good many things I don't," said Charlie, whose grimness had evidently relaxed a little at the lad's display of mettle. Meanwhile, my temper was beginning to rise on behalf of our young passenger.

"I tell you what, Charlie," I interposed; "if you are going to keep this up, you'd better count me out on this trip and set us both ashore at West End. You're making a fool of yourself. The lad's all right. Any one can see with half an eye there's no harm in him."

The boy shot me a warm glance of gratitude.

"All right," agreed Charlie, beginning to lose his temper too, "I'm damned if I don't." And, his hand on the tiller, he made as if to turn the boat about and tack for the shore.

"No! no!" cried the boy, springing between us, and appealingly laying one hand on Charlie's shoulder, the other on mine. "You mustn't let me spoil your trip. I'll compromise. And, skipper, I'll tell your friend here all there is to tell—everything—I swear—if you will leave it to his judgment."
