“Couldn’t fall far,” his friend remarked. “The heavy vegetation would catch you before you’d fallen ten feet. But even then I wouldn’t care to lose my balance and come up against a tree.”

The young explorers stumbled on to the bottom and then began the ascent of the opposite side.

Suddenly they heard a vicious snarl and looked back to see that a large, powerful jaguar was poised ready to spring. Its wicked eyes shone like beads as it bared its sharp teeth.

Slowly the youths raised their rifles and took steady aim. Joe was the first to pull the trigger, and a moment later Bob followed.

A part snarl, part whine came from the beast, and it weaved as if going to fall. But it righted itself and then again prepared to spring.

“It’s up to you, Bob,” murmured Joe in a tone that he tried to keep steady. “My rifle’s empty. Can’t get it loaded in time.”

Bob frowned.

A second later he raised his gun to fire, but it caught on a sharp protruding branch and was wrenched from his grasp. With a frightened glance at the huge cat he turned to run, and Joe was at his heels.

The boys well knew that they had little chance of escape in that dense jungle, but they resolved to retreat as fast as their legs would carry them. And the fact that the jaguar was severely wounded gave them courage to run with all the strength they could muster.
