Quickly he made the rope fast to a stout branch, and as the panther, in answer to his summons, leaped into sight, Tarzan dropped to the earth beside the struggling and infuriated Numa, and with a long sharp knife sprang upon him at one side even as Sheeta did upon the other.
The panther tore and rent Numa upon the right, while the ape-man struck home with his stone knife upon the other, so that before the mighty clawing of the king of beasts had succeeded in parting the rope he hung quite dead and harmless in the noose.
And then upon the jungle air there rose in unison from two savage throats the victory cry of the bull-ape and the panther, blended into one frightful and uncanny scream.
As the last notes died away in a long-drawn, fearsome wail, a score of painted warriors, drawing their long war-canoe upon the beach, halted to stare in the direction of the jungle and to listen.
CHAPTER V.
Mugambi
By the time that Tarzan had travelled entirely about the coast of the island, and made several trips inland from various points, he was sure that he was the only human being upon it.
Nowhere had he found any sign that men had stopped even temporarily upon this shore, though, of course, he knew that so quickly does the rank vegetation of the tropics erase all but the most permanent of human monuments that he might be in error in his deductions.
The day following the killing of Numa, Tarzan and Sheeta came upon the tribe of Akut. At sight of the panther the great apes took to flight, but after a time Tarzan succeeded in recalling them.
It had occurred to him that it would be at least an interesting experiment to attempt to reconcile these hereditary enemies. He welcomed anything that would occupy his time and his mind beyond the filling of his belly and the gloomy thoughts to which he fell prey the moment that he became idle.
To communicate his plan to the apes was not a particularly difficult matter, though their narrow and limited vocabulary was strained in the effort; but to impress upon the little, wicked brain of Sheeta that he was to hunt with and not for his legitimate prey proved a task almost beyond the powers of the ape-man.
