During the several seconds that had elapsed since he cast the rope the Waz-don warriors had remained inert as though paralyzed by wonder or by terror. Now, again, one of them found his voice and his head and straightway, shrieking invectives at the strange intruder, started upward for the ape-man, urging his fellows to attack. This man was the closest to Tarzan. But for him the ape-man could easily have reached Ta-den's side as the latter was urging him to do. Tarzan raised the body of the dead Waz-don above his head, held it poised there for a moment as with face raised to the heavens he screamed forth the horrid challenge of the bull apes of the tribe of Kerchak, and with all the strength of his giant sinews he hurled the corpse heavily upon the ascending warrior. So great was the force of the impact that not only was the Waz-don torn from his hold but two of the pegs to which he clung were broken short in their sockets. As the two bodies, the living and the dead, hurtled downward toward the foot of the cliff a great cry arose from the Waz-don. "Jad-guru-don! Jad-guru-don!" they screamed, and then: "Kill him! Kill him!" And now Tarzan stood in the recess beside Ta-den. "Jad-guru-don!" repeated the latter, smiling--"The terrible man! Tarzan the Terrible! They may kill you, but they will never forget you." "They shall not ki--What have we here?" Tarzan's statement as to what "they" should not do was interrupted by a sudden ejaculation as two figures, locked in deathlike embrace, stumbled through the doorway of the cave to the outer porch. One was Om-at, the other a creature of his own kind but with a rough coat, the hairs of which seemed to grow straight outward from the skin, stiffly, unlike Om-at's sleek covering. The two were quite evidently well matched and equally evident was the fact that each was bent upon murder. They fought almost in silence except for an occasional low growl as one or the other acknowledged thus some new hurt. Tarzan, following a natural impulse to aid his ally, leaped forward to enter the dispute only to be checked by a grunted admonition from Om-at. "Back!" he said. "This fight is mine, alone." The ape-man understood and stepped aside. "It is a gund-bar," explained Ta-den, "a chief-battle. This fellow must be Es-sat, the chief. If Om-at kills him without assistance Om-at may become chief."
