The beast that held her saw it too and growled ominously but it did not relinquish its hold upon her hair. It crouched as though waiting an attack, and it increased the volume and frequency of its growls until the horrid sounds reverberated through the gorge, drowning even the deep bellowings of the beasts below, whose mighty thunderings had broken out anew with the sudden commotion from the high-flung cave. The beast that held her crouched and the creature that faced it crouched also, and growled--as hideously as the other. Pan-at-lee trembled. This was no Ho-don and though she feared the Ho-don she feared this thing more, with its catlike crouch and its beastly growls. She was lost--that Pan-at-lee knew. The two things might fight for her, but whichever won she was lost. Perhaps, during the battle, if it came to that, she might find the opportunity to throw herself over into the Kor-ul-GRYF. The thing that held her she had recognized now as a Tor-o-don, but the other thing she could not place, though in the moonlight she could see it very distinctly. It had no tail. She could see its hands and its feet, and they were not the hands and feet of the races of Pal-ul-don. It was slowly closing upon the Tor-o-don and in one hand it held a gleaming knife. Now it spoke and to Pan-at-lee's terror was added an equal weight of consternation. "When it leaves go of you," it said, "as it will presently to defend itself, run quickly behind me, Pan-at-lee, and go to the cave nearest the pegs you descended from the cliff top. Watch from there. If I am defeated you will have time to escape this slow thing; if I am not I will come to you there. I am Om-at's friend and yours." The last words took the keen edge from Pan-at-lee's terror; but she did not understand. How did this strange creature know her name? How did it know that she had descended the pegs by a certain cave? It must, then, have been here when she came. Pan-at-lee was puzzled. "Who are you?" she asked, "and from whence do you come?" "I am Tarzan," he replied, "and just now I came from Om-at, of Kor-ul-JA, in search of you."
