Suddenly Dave saw the man start to rise up as if in great alarm. A look of horror was in his gleaming eyes. With a yell he toppled backwards. The amazed Dave saw him roll down the bluff incline. The native turned over and over, his head struck a great rock in the way with a fearful click. The blood flew from the wound and deluged the native's face and he lay like one dead, his body suspended over a bent sapling.

"Why," exclaimed the startled Dave, "what made him do that? Mercy!"

A lithe, sinuous form cut the air, coming from the thick shrubbery just back of Dave. It landed where the native had sat. Dave understood now. It was a panther.

His blood ran cold as the animal, disappointed of its expected prey, turned quickly, facing him. From former experiences on the island Dave knew that he confronted a foe dangerous and bloodthirsty in the extreme.

The native panther was feared by the natives greatly. It was a small animal, but ferocious to a degree and enormously strong in forefeet and teeth.

Dave, bound, unarmed, felt himself completely at the mercy of the animal. He shrank back, naturally, as it began to describe a semicircle. It crept low to the ground, uttering a harsh, hissing snarl. Its eyes were fixed intently on its intended victim.

Dave watched the fatal circle narrow. The panther came to a pause, a crouch. It shot up from the ground.

Dave had prepared for this first onset. He realized, however, that, helpless as he was, his agility could not eventually save him.

The youth made a leap as the panther sprang at him. Through a remarkable circumstance Dave's rush drew the big vine out. The panther met it coming up, was caught across the breast, and was sent hurtling back violently.

It fell to the ground, Dave ran at it. He ventured boldly, for the chances of escape were desperate. Dave delivered one kick at the prostrate animal. His foot partly landed in its gaping mouth.
