swiftly； came the devil…eyed lion of the mountains of Pal…ul…don。
Pan…at…lee was lost。 Death was inevitable。 Of this there could be no doubt； but to die beneath the rending fangs of the carnivore； congenital terror of her kindit was unthinkable。 But there was an alternative。 The lion was almost upon heranother instant and he would seize her。 Pan…at…lee turned sharply to her left。 Just a few steps she took in the new direction before she disappeared over the rim of Kor…ul…lul。 The baffled lion； planting all four feet； barely stopped upon the verge of the abyss。 Glaring down into the black shadows beneath he mounted an angry roar。
Through the darkness at the bottom of Kor…ul…ja； Om…at led the way toward the caves of his people。 Behind him came Tarzan and Ta…den。 Presently they halted beneath a great tree that grew close to the cliff。
〃First；〃 whispered Om…at； 〃I will go to the cave of Pan…at…lee。 Then will I seek the cave of my ancestors to have speech with my own blood。 It will not take long。 Wait hereI shall return soon。 Afterward shall we go together to Ta…den's people。〃
He moved silently toward the foot of the cliff up which Tarzan could presently see him ascending like a great fly on a wall。 In the dim light the ape…man could not see the pegs set in the face of the cliff。 Om…at moved warily。 In the lower tier of caves there should be a sentry。 His knowledge of his people and their customs told him； however； that in all probability the sentry was asleep。 In this he was not mistaken； yet he did not in any way abate his wariness。 Smoothly and swiftly he ascended toward the cave of Pan…at…lee while from below Tarzan and Ta…den watched him。
〃How does he do it？〃 asked Tarzan。 〃I can see no foothold upon that vertical surface and yet he appears to be climbing with the utmost ease。〃
Ta…den explained the stairway of pegs。 〃You could ascend easily；〃 he said； 〃although a tail would be of great assistance。〃
They watched until Om…at was about to enter the cave of Pan…at…lee without seeing any indication that he had been observed and then； simultaneously； both saw a head appear in the mouth of one of the lower caves。 It was quickly evident that its owner had discovered Om…at for immediately he started upward in pursuit。 Without a word Tarzan and Ta…den sprang forward toward the foot of the cliff。 The pithecanthropus was the first to reach it and the ape…man saw him spring upward for a handhold on the lowest peg above him。 Now Tarzan saw other pegs roughly paralleling each other in zigzag rows up the cliff face。 He sprang and caught one of these； pulled himself upward by one hand until he could reach a second with his other hand； and when he had ascended far enough to use his feet； discovered that he could make rapid progress。 Ta…den was outstripping him； however； for these precarious ladders were no novelty to him and； further； he had an advantage in possessing a tail。
Nevertheless； the ape…man gave a good account of himself； being presently urged to redoubled efforts by the fact that the Waz…don above Ta…den glanced down and discovered his pursuers just before the Ho…don overtook him。 Instantly a wild cry shattered the silence of the gorgea cry that was immediately answered by hundreds of savage throats as warrior after warrior emerged from the entrance to his cave。
The creature who had raised the alarm had now reached the recess before Pan…at…lee's cave and here he halted and turned to give battle to Ta…den。 Unslinging his club which had hung down his back from a thong about his neck he stood upon the level floor of the entrance…way effectually blocking Ta…den's ascent。 From all directions the warriors of Kor…ul…ja were swarming toward the interlopers。 Tarzan； who had reached a point on the same level with Ta…den but a little to the latter's left； saw that nothing short of a miracle could save them。 Just at the ape…man's left was the entrance to a cave that either was deserted or whose occupants had not as yet been aroused； for the level recess remained unoccupied。 Resourceful was the alert mind of Tarzan of the Apes and quick to respond were the trained muscles。 In the time that you or I might give to debating an action he would accomplish it and now； though only seconds separated his nearest antagonist from him； in the brief span of time at his disposal he had stepped into the recess； unslung his long rope and leaning far out shot the sinuous noose； with the precision of long habitude； toward the menacing figure wielding its heavy club above Ta…den。 There was a momentary pause of the rope…hand as the noose sped toward its goal； a quick movement of the right wrist that closed it upon its victim as it settled over his head and then a surging tug as； seizing the rope in both hands； Tarzan threw back upon it all the weight of his great frame。
Voicing a terrified shriek； the Waz…don lunged headforemost from the recess above Ta…den。 Tarzan braced himself for the coming shock when the creature's body should have fallen the full length of the rope and as it did there was a snap of the vertebrae that rose sickeningly in the momentary silence that had followed the doomed man's departing scream。 Unshaken by the stress of the suddenly arrested weight at the end of the rope； Tarzan quickly pulled the body to his side that he might remove the noose from about its neck； for he could not afford to lose so priceless a weapon。
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 kiWhat 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。〃
Tarzan smiled。 It was the law of his own junglethe law of the tribe of Kerchak； the bull apethe ancient law of primitive man that needed but the refining influences of civilization to introduce the hired dagger and the poison cup。 Then his attention was drawn to the outer edge of the vestibule。 Above it appeared the shaggy face of one of Es…sat's warriors。 Tarzan sprang to intercept the man； but Ta…den was there ahead of him。 〃Back！〃 cried the Ho…don to the newcomer。 〃It is gund…bar。〃 The fellow looked scrutinizingly at the two fighters； then turned his face downward toward his fellows。 〃Back！〃 he cried； 〃it is gund…bar between Es…sat and Om…at。〃 Then he looked back at Ta…den and Tarzan。 〃Who are you？〃 he asked。
〃We are Om…at's friends；〃 replied Ta…den。
The fellow nodded。 〃We will attend to you later；〃 he said and disappeared below the edge of the recess。
The battle upon the ledge continued with unabated ferocity； Tarzan and Ta…den having difficulty in keeping out of the way of the contestants who tore and beat at each other with hands and feet and lashing tails。 Es…sat was unarmedPan…at…lee had seen to thatbut at Om…at's side swung a sheathed knife which he made no effort to draw。 That would have been contrary to their savage and primitive code for the chief…battle must be fought with nature's weapons。
Sometimes they separated for an instant only to rush upon each other again with all the ferocity and nearly the strength of mad bulls。 Presently one of them tripped the other but in that viselike embrace one could not fall aloneEs…sat dragged Om…at with him； toppling upon the brink of the niche。 Even Tarzan held his breath。 There they surged to and fro perilously for a moment and then the inevitable happenedthe two； locked in murderous embrace； rolled over the edge and disappeared from the ape…man's view。
Tarzan voiced a suppressed sigh for he had liked Om…at and then； with Ta…den； approached the edge and looked over。 Far below； in the dim light of the coming dawn； two inert forms should be lying stark in death； but； to Tarzan's amazement； such was far from the sight that met his eyes。 Instead； there were the two figures still vibrant with life and still battling only a few feet below him。 Clinging always to the pegs with two holdsa hand and a foot； or a foot and a tail； they seemed as much at home upon the perpendicular wall as upon the level surface of the vestibule； but now their tactics were slightly altered； for each seemed particularly bent upon dislodging his a
