CHAPTER II

JACK’S DARING RESCUE

Straight toward the swimming boy swam Jack, rapidly estimating the distance between them and the distance to be covered by the shark, the presence of which was not yet known by the younger boy.

He could swim, but he was more or less encumbered by his clothes, wide bottomed trousers and full shirt, and could not make as good progress as Jack in any event.

Then, as he was only a little fellow, and probably not accustomed to swimming very far out of his depth, Jack looked for his strength giving out at any moment.

“Keep up, J.W., you are doing fine!” he shouted, swimming straight on with a long, even stroke, which carried him rapidly toward the struggling boy.

Then some one on the yacht, with more anxiety than good judgment, shouted out so that all could hear him: 

“Look out for the shark, look out!”

The instant that the younger boy heard this, he turned his head and cast a frightened look behind him, seeing the sharp fin just beginning to turn over in the water.

“Don’t look, Jesse W., don’t look, swim straight ahead!” cried Jack, who had come up with the boy.

Then he dove deep down so as to come up under the shark before he could turn and rush at the boy so near him.

Down went Jack, and presently began to rise, seeing the white belly of the man eater just above him.

With a fierce upward thrust of his right arm, which held the knife he had taken from the cook, he plunged the blade into the creature’s vitals, drawing it downward and toward him, and turning his hand as he drew, thus making a jagged cut, and fairly laying open the shark’s belly.

Young Smith, encouraged by Jack’s shout, had darted ahead with his little remaining strength, not again looking back, and knowing too well what was about to happen when Jack dove.

As the shark, mortally wounded, floated away, to be eaten by others of his kind, Jesse W. suddenly became faint and felt himself giving out.

Jack arose in a moment, however, and called out cheerily: 

“Hold on a moment, young fellow, and I’ll be there.  You mustn’t give out yet, because they haven’t put about to take us aboard.”

The younger boy held out till Jack reached him, but seemed about to go under again when Jack said quickly: 

“Here, get on my back and you won’t have to swim.  I’ll tow you all right, and you can get rested.”

“Did you kill him, Jack?” gasped the younger boy, as he obeyed the older one’s instructions.

“Yes, yes, but never mind about that.  Don’t look behind you, just look straight ahead.  I don’t know that there’s anything there anyhow, but it is always a good plan to look the way you’re going to avoid accidents.”

“You’re a funny fellow, Jack,” said the other.  “You don’t want me to see the sharks and be frightened.”
