“Shoot it, Frank; it’ll get away!”

Frank did as he was bid, but the bullets had no apparent effect—the great creature waddled on even faster than before.

Arthur, almost beside himself with excitement, jumped on to the broad, rounded back, and yelled like an Indian, swaying to and fro in his efforts to keep his balance on the living platform. Then suddenly realizing that he held a hatchet in his flourishing right hand, he reached forward and struck it deeply into the snake-like skull.

CHAPTER XI

LOST ON CAPTIVE ISLAND

Charlotte Harbor was so flooded with moonlight that the little wind ripples shone like frosted silver. The “Gazelle,” lying peacefully at anchor, floated like a shadow on the placid water. Kenneth lay asleep on the cabin roof, where he had moved from the more cramped position in the cockpit. Soundly as a tired man should, he slept; then, disturbed by dreams of battles with wind and wave, he stirred, working his arms and legs like a dog who has visions of the chase. At first he moved uneasily, but still lay in the same position, then, still dead asleep, began to work over to the yacht’s rail. A long, strong roller came in from the Gulf and rocked the yawl so that the deck sloped sharply; there was a sudden great splash, and then all was still, the ripples circling away from the agitated spot. Suddenly the waters began to show signs of a struggle below, and an instant later a bedraggled white figure splashed to the surface and began spouting and spluttering. Kenneth coughed and wheezed as he got rid of a large quantity of warm, salt liquid, and between gasps called himself all the names his water-soaked brain could think of. He finally pulled himself up on deck—rather weakly—and lay down in the cockpit to rest a minute.

“Well, I’ll be jiggered, if that wasn’t the greatest fool stunt! I am mighty glad the other fellows were not around. I should never have heard the last of it.”

He turned to go below, and, as he did so, he heard the far distant crack of a rifle.

“Must be something doing with the turtles,” he thought.
