later he was looking down upon a scene that might well have made him question the credibility of his eyesight.
He lay upon the edge of a low cliff, and below him were four creatures such as might have materialized only from a bad dream. They had the bodies of men-squat, stocky men. Their faces, their shoulders, and their breasts were covered with long, brown hair. From opposite sides of their foreheads protruded short, heavy horns much like the horns of a bison; and they had tails with a bushy tuft of hair at the end. From their throats issued the bull-like bellows he had heard, as well as the speech of men.
They carried no weapons; and it was evident that they were being held at bay by some creature or creatures that were hidden from the sight of von Horst by the overhanging of the cliff upon which he lay, for every time they started to approach closer to the cliff fragments of stone would fly out and drive them back. This always set them to bellowing angrily; and sometimes one or another of them would stamp the ground or paw up the dust with a foot, for all the world like a mad bull; so that von Horst thought of them then and always as the bison-men.
From the fact that missiles were being hurled at these creatures by their prey, von Horst assumed that the latter might be human beings; though, of course, in Pellucidar they might be any strange variety of man or beast. That they were bison-men, he doubted; as he noticed that none of the four threw rocks in return, as he was reasonably certain they would have done had they been sufficiently intelligent.
Occasionally he caught a word or two as the four spoke to one another, and he discovered that they spoke the common language of the human beings of Pellucidar. Presently one of them raised his voice and shouted to whatever it was they had brought to bay at the foot of the cliff.
'Stop throwing rocks, gilak,' he said. 'It will only go worse with you when we get you, and we shall get you —be sure of that. You have neither food nor water; so you must come out or starve.'
'What do you want of us?' demanded a voice from the bottom of the cliff.
'We want the woman,' replied the bison-man who had previously spoken.
'You don't want me?' demanded the voice.
'Only to kill you; but if you give us the woman, we will spare you.'
'How do I know you'll keep your word?'
'We do not lie,' replied the bison-man. 'Bring her here and we will let you go.'
'I bring her,' announced the voice from below.
'The son of a pig!' ejaculated von Horst beneath his breath.
A moment later he saw a man emerge from below the overhang of the cliff, dragging a woman by the hair. Instantly he was upon his feet, charged with horror and with rage; for at the first glance he had recognized them —Skruf and La-ja.
A sheer drop of thirty or forty feet to the ground below left him temporarily helpless, and for a moment he could only stand and look down upon the tragedy; then he fitted an arrow to his bow, but Skruf was partially shielded by the body of the girl. Von Horst could not shoot without endangering her.
'La-ja!' he cried. The girl tried to turn her head back in the direction of his voice. Skruf and the bison-men looked up at the figure standing upon the top of the cliff. 'One side, La-ja!' he called. 'Go to one side!'
Instantly she swung to the right, turning Skruf sideways so that he was fully exposed to the archer whose bow was already drawn. The bow-string twanged. Skruf screamed and went down clutching at the feathered shaft sunk deep in his body, and as he fell he released his hold upon La-ja's hair.
'Run!' commanded von Horst. 'Run parallel to the cliff and I will follow until I find a way down.'
Already, recovered from their first surprise, the bison-men were running toward the girl; but she had a little start, and with luck she might outdistance them. Their heavy, squat figures did not seem designed for speed.
Von Horst turned and called to Old White to follow; then he ran along the cliff-top a little behind La-ja. Almost at once he realized that the appearance of the bison-men belied their agility—they were overhauling the girl. Again he fitted an arrow to his bow. Just for an instant he paused—long enough to take aim at the leading bison-man and release the shaft; then he sprang forward, but he had lost ground that he could not regain. However, he had temporarily widened the gap between La-ja and her pursuers; for the leading bison-man lay groveling on the ground, an arrow through his back.
The others were closing up, and again von Horst was forced to stop and shoot. As before, the girl's closest pursuer pitched to the ground. The fellow rolled over and over, but when he stopped he lay very still. Now there were only two, but again von Horst had lost distance. He tried to gain on them but he could not. At last he halted and sent two more arrows after the remaining bison-men. The nearer fell, but he missed the other. Twice after that he loosed his shafts; but the last one fell short, and he knew that the man was out of range—out of range and rapidly gaining on his quarry. Just ahead of the fleeing girl loomed a forest of giant trees. If she could reach these she might elude her pursuer, and she was fleet of foot.
In silence the three raced on, von Horst on the cliff-top barely maintaining his ground; then the girl disappeared among the boles of the great trees; and a moment later the bison-man followed her. Von Horst was frantic. The interminable cliff offered no avenue of descent. There was nothing to do but continue on until he found such a place, but in the meantime what would become of La-ja?
To have found her so unexpectedly, to have been so close to her, and then to have lost her left him heart-sick and hopeless. Still, he knew now that she lived; and that was something. And now, close behind him, he heard the familiar trumpeting of Old White; and a moment later a hairy trunk encircled him and swung him to the now familiar seat in the hollow back of the massive skull.
Just beyond the edge of the forest they came upon a rift in the escarpment; and here the mammoth, finding precarious foot-hold, picked his way carefully down. Von Horst turned him back to the point at which La-ja had disappeared; but here he was forced to dismount, as the trees grew too closely to permit the great beast to enter the forest, and he could neither uproot nor push over the giant boles.
As von Horst left Old White to enter the forest he had a premonition that this was the last time that he would ever see his faithful friend and ally; and it was with a heavy heart that he passed into the grim, forbidding wood.
Only for an instant was his mind occupied with thoughts of Old White, for at a distance he heard a faint scream; and then a voice called his name twice—'Von! Von!'—the voice of the woman he loved.
XIX – KRU
GUIDED ONLY BY the memory of that faint cry in the distance, von Horst pushed on into the forest. Never had he seen trees of such size growing in such close proximity, often so near to one another that there was just room for him to pass between. There was no trail, and because of the zig-zag course he was forced to pursue he soon lost all sense of direction. Twice he had called La-ja's name aloud, hoping that she would reply and thus give him a new clue to her whereabouts, but there had been no answer. He realized that about all he had accomplished had been to apprize her captor that he was being pursued and thus put him on his guard; so, though he moved as rapidly as he could, he was most watchful.
As he hurried on he became more and more imbued with a sense of frustration and the futility of his search, feeling that he was quite probably moving in circles and getting nowhere. He was even impressed by the probability that he might never even find his way out of this labyrinthine maze of gloomy trees, to say nothing of reaching La-ja in time to be of any service to her. And thus his mind was occupied by gloomy thoughts when he came suddenly to the end of the forest. Before him lay the mouth of a canyon leading into low but rugged hills, and here at last was a trail. It wound, well-marked, into the canyon.
With renewed hope von Horst stepped confidently out to follow wherever the way might lead; for a brief examination told his now practiced eyes that someone had recently entered the canyon at this point, and faintly in the dust of the trail he saw the imprint of a tiny foot. The canyon was little more than a narrow, rocky gorge winding snake-like into the hills; and as he proceeded he passed the mouths of other similar gorges that entered it at intervals; but the main trail was plain, and he continued upon it, certain now that he must soon overtake La-ja and her captor.
He had been for some little time in the gorge and was becoming impatient with each fresh disappointment when he rounded a bend and did not see those he sought ahead of him, when he heard a noise behind. He turned quickly and saw a bison-man creeping stealthily upon him. The instant that the fellow realized he had been
