Presently a door in one side of the arena wall was opened to admit a huge, shaggy, bull-like creature.
"A Bos," whispered Perry, excitedly. "His kind roamed the outer crust with the cave bear and the mammoth ages and ages ago. We have been carried back a million years, David, to the childhood of a planet—is it not wondrous?"
But I saw only the raven hair of a half-naked girl, and my heart stood still in dumb misery at the sight of her, nor had I any eyes for the wonders of natural history. But for Perry and Ghak I should have leaped to the floor of the arena and shared whatever fate lay in store for this priceless treasure of the Stone Age.
With the advent of the Bos—they call the thing a thag within Pellucidar—two spears were tossed into the arena at the feet of the prisoners. It seemed to me that a bean shooter would have been as effective against the mighty monster as these pitiful weapons.
As the animal approached the two, bellowing and pawing the ground with the strength of many earthly bulls, another door directly beneath us was opened, and from it issued the most terrific roar that ever had fallen upon my outraged ears. I could not at first see the beast from which emanated this fearsome challenge, but the sound had the effect of bringing the two victims around with a sudden start, and then I saw the girl's face—she was not Dian! I could have wept for relief.
And now, as the two stood frozen in terror, I saw the author of that fearsome sound creeping stealthily into view. It was a huge tiger—such as hunted the great Bos through the jungles primeval when the world was young. In contour and markings it was not unlike the noblest of the Bengals of our own world, but as its dimensions were exaggerated to colossal proportions so too were its colorings exaggerated. Its vivid yellows fairly screamed aloud; its whites were as eider down; its blacks glossy as the finest anthracite coal, and its coat long and shaggy as a mountain goat. That it is a beautiful animal there is no gainsaying, but if its size and colors are magnified here within Pellucidar, so is the ferocity of its disposition. It is not the occasional member of its species that is a man hunter—all are man hunters; but they do not confine their foraging to man alone, for there is no flesh or fish within Pellucidar that they will not eat with relish in the constant efforts which they make to furnish their huge carcasses with sufficient sustenance to maintain their mighty thews.
Upon one side of the doomed pair the thag bellowed and advanced, and upon the other tarag, the frightful, crept toward them with gaping mouth and dripping fangs.
The man seized the spears, handing one of them to the woman. At the sound of the roaring of the tiger the bull's bellowing became a veritable frenzy of rageful noise. Never in my life had I heard such an infernal din as the two brutes made, and to think it was all lost upon the hideous reptiles for whom the show was staged!
The thag was charging now from one side, and the tarag from the other. The two puny things standing between them seemed already lost, but at the very moment that the beasts were upon them the man grasped his companion by the arm and together they leaped to one side, while the frenzied creatures came together like locomotives in collision.
There ensued a battle royal which for sustained and frightful ferocity transcends the power of imagination or description. Time and again the colossal bull tossed the enormous tiger high into the air, but each time that the huge cat touched the ground he returned to the encounter with apparently undiminished strength, and seemingly increased ire.
For a while the man and woman busied themselves only with keeping out of the way of the two creatures, but finally I saw them separate and each creep stealthily toward one of the combatants. The tiger was now upon the bull's broad back, clinging to the huge neck with powerful fangs while its long, strong talons ripped the heavy hide into shreds and ribbons.
For a moment the bull stood bellowing and quivering with pain and rage, its cloven hoofs widespread, its tail lashing viciously from side to side, and then, in a mad orgy of bucking it went careening about the arena in frenzied attempt to unseat its rending rider. It was with difficulty that the girl avoided the first mad rush of the wounded animal.
All its efforts to rid itself of the tiger seemed futile, until in desperation it threw itself upon the ground, rolling over and over. A little of this so disconcerted the tiger, knocking its breath from it I imagine, that it lost its hold and then, quick as a cat, the great thag was up again and had buried those mighty horns deep in the tarag's abdomen, pinning him to the floor of the arena.
The great cat clawed at the shaggy head until eyes and ears were gone, and naught but a few strips of ragged, bloody flesh remained upon the skull. Yet through all the agony of that fearful punishment the thag still stood motionless pinning down his adversary, and then the man leaped in, seeing that the blind bull would be the least formidable enemy, and ran his spear through the tarag's heart.
As the animal's fierce clawing ceased, the bull raised his gory, sightless head, and with a horrid roar ran headlong across the arena. With great leaps and bounds he came, straight toward the arena wall directly beneath where we sat, and then accident carried him, in one of his mighty springs, completely over the barrier into the midst of the slaves and Sagoths just in front of us. Swinging his bloody horns from side to side the beast cut a wide swath before him straight upward toward our seats. Before him slaves and gorilla-men fought in mad stampede to escape the menace of the creature's death agonies, for such only could that frightful charge have been.
Forgetful of us, our guards joined in the general rush for the exits, many of which pierced the wall of the amphitheater behind us. Perry, Ghak, and I became separated in the chaos which reigned for a few moments after the beast cleared the wall of the arena, each intent upon saving his own hide.
I ran to the right, passing several exits choked with the fear mad mob that were battling to escape. One would have thought that an entire herd of thags was loose behind them, rather than a single blinded, dying beast; but such is the effect of panic upon a crowd.
VII
FREEDOM
Once out of the direct path of the animal, fear of it left me, but another emotion as quickly gripped me—hope of escape that the demoralized condition of the guards made possible for the instant.
I thought of Perry, but for the hope that I might better encompass his release if myself free I should have put the thought of freedom from me at once. As it was I hastened on toward the right searching for an exit toward which no Sagoths were fleeing, and at last I found it—a low, narrow aperture leading into a dark corridor.
Without thought of the possible consequence, I darted into the shadows of the tunnel, feeling my way along through the gloom for some distance. The noises of the amphitheater had grown fainter and fainter until now all was as silent as the tomb about me. Faint light filtered from above through occasional ventilating and lighting tubes, but it was scarce sufficient to enable my human eyes to cope with the darkness, and so I was forced to move with extreme care, feeling my way along step by step with a hand upon the wall beside me.
Presently the light increased and a moment later, to my delight, I came upon a flight of steps leading upward, at the top of which the brilliant light of the noonday sun shone through an opening in the ground.
