No panther that ever lived could withstand that crushing impact, and the cougar went limp, lost his hold on the branch, and went crashing to the ground, twenty feet below, where he lay twitching convulsively.

“Now’s our chance to make an end of this customer for once and all!” yelled Bobby. “Come on down, fellows, and we’ll finish him this time.”

Lee hastily scrambled back from the end of the branch, and all three boys slid down the trunk of the tree to where the cougar lay, still stunned from the terrific blow and from its fall.

“Quick,” said Bobby, “grab hold of him, and we’ll throw him into that big bog-hole we passed when we left the main path.”

“Right!” exclaimed Fred. “But we’ll have to act mighty quick. He’s apt to come to life any second.”

It was all the boys could do to lift the big brute, but, with the strength of desperation, they managed it somehow, and half carried, half dragged, the unconscious panther to the slimy green pit that they had almost tumbled into themselves while making for the tree. The pit was surrounded by an expanse of treacherous quicksand, and into this they shoved the cougar. The greedy quicksand received its victim with avidity, drawing the cougar down and down into its slimy depths, until with a dull sucking sound it closed over the bloodthirsty brute’s head.

The boys watched, fascinated, and almost found it in their hearts to pity their late enemy. He was gone as completely as though he had never existed, and the treacherous sand stretched out smooth and unbroken, not a quiver on its surface to tell that it had added one more victim to its already long list.

“Gee,” exclaimed Bobby with a shudder, “that’s a terrible way to die, although that brute deserved all that was coming to him.”

“Well, it’s pretty certain that he won’t bother us any more,” remarked Fred. “And I think we’re mighty lucky to be alive.”

“I’ll say so!” exclaimed Lee, fervently. “I gave myself up for lost when I found myself out on that limb with the panther not ten feet away from me. That was an awful wallop you fellows gave him.”
