Most of them kept on down the valley, disappearing from the man's view where the valley turned behind the hills; but he saw a few large sheep run into a canyon between two nearby cones, and these he decided to pursue. As he entered the canyon he saw that it narrowed rapidly, evidently having been formed by the erosion of water which had uncovered the broken lava rocks of a previous flow. Only a narrow trail ran between some of the huge blocks, hundreds of which were scattered about in the wildest confusion.
The sheep had been running rapidly; and as they had started considerably ahead of him, he knew that they must be out of earshot by now; so he made no effort to hide his pursuit, but moved at a quick walk along the winding trail between the rocks. He came at last to a point where the trail debouched upon a wider portion of the canyon, and as he was about to enter it he heard plainly the sound of running feet coming toward him from the upper portion of the canyon, which he could not see. And then he heard a disconcerting series of growls and snarls from the same direction. He had already seen enough of Pellucidar and its bloodthirsty fauna to take it for granted that practically everything that had life might be considered a potential menace; so he leaped quickly behind a large lava rock and waited.
He had scarcely concealed himself, when a man came running from the upper end of the gorge. It seemed to von Horst that the newcomer was as fleet as a deer. And it was well for him that he was fleet, for behind him came the author of the savage snarls and growls that von Horst had heard—a great, dog-like beast as large and savage as a leopard. As fleet as the man was, however, the beast was gaining on him; and it was apparent to von Horst that it would overtake its quarry and drag him down before he had crossed the open space.
The fellow was armed only with a crude stone knife, which he now carried in one hand, as though determined to make what fight for his life he might when he could no longer outdistance his pursuer; but he must have realized, as did von Horst, how futile his weapon would be against the powerful beast bearing down upon him.
There was no question in von Horst's mind as to what he should do. He could not stand idly by and see a human being torn to pieces by the cruel fangs of the Hyaenodon, and so he stepped from behind the rock that had concealed him from both the man and the beast; and, jumping quickly to one side where he might obtain an unobstructed shot at the creature, raised his pistol, took careful aim, and fired. It was not a lucky shot; it was a good shot, perfect. It bored straight through the left side of the brute's chest and buried itself in his heart. With a howl of pain and rage, the carnivore bounded forward almost to von Horst; then it crumpled at his feet, dead.
The man it had been pursuing, winded and almost spent, came to a halt. He was wide-eyed and trembling as he stood staring at von Horst in wonder and amazement. As the latter turned toward him he backed away, gripping his knife more tightly.
"Go away!" he growled. "I kill!"
He spoke the same language that Dangar had taught von Horst, which, he had explained, was the common language of all Pellucidar; a statement that the man from the outer crust had doubted possible.
"You kill what?" demanded von Horst.
"You."
"Why do you wish to kill me?"
"So that I shall not be killed by you."
"Why should I kill you?" asked von Horst. "I just saved your life. If I had wished you to die, I could have just left you to that beast."
The man scratched his head. "That is so," he admitted after some reflection; "but still I do not understand it. I am not of your tribe; therefore there is no reason why you should not wish to kill me. I have never seen a man like you before. All other strangers that I have met have tried to kill me. Then, too, you cover your body with strange skins. You must come from a far country."
"I do," von Horst assured him; "but the question now is, are we to be friends or enemies?"
Again the man ran his nails through his shock of black hair meditatively. "It is very peculiar," he said. "It is something that I have never before heard of. Why should we be friends?"
"Why should we be enemies?" countered von Horst. "Neither one of us has ever harmed the other. I am from a very far country, a stranger in yours. Were you to come to my country, you would be treated well. No one would wish to kill you. You would be given shelter and fed. People would be kindly toward you, just because they are kindly by nature and not because you could be of any service to them. Here, it is far more practical that we be friends; because we are surrounded by dangerous beasts, and two men can protect themselves better than one.
"However, if you wish to be my enemy, that is up to you. I may go my way, and you yours; or, if you wish to try to kill me, that, too, is a matter for you to decide; but do not forget how easily I killed this beast here. Just as easily could I kill you."
"Your words are true words," said the man. "We shall be friends. I am Skruf. Who are you?"
In his conversations with Dangar, von Horst had noticed that no Pellucidarians that the other had mentioned had more than one name, to which was sometimes added a descriptive title such as the Hairy One, the Sly One, the Killer, or the like; and as Dangar usually called him von, he had come to accept this as the name he would use in the inner world; so this was the name that he gave to Skruf.
"What are you doing here?" asked the man. "This is a bad country because of the Trodons."
"I have found it so," replied von Horst. "I was brought here by a Trodon."
The other eyed him skeptically. "You would be dead now if a Trodon had ever seized you."
"One did, and took me to its nest to feed its young. I and another man escaped."
"Where is he?"
"Back by the river in our camp. I was hunting for food when I met you. I was following some sheep up this canyon. What were you doing here?"
"I was escaping from the Mammoth Men," replied Skruf. "Some of them captured me. They were taking me back to their country to make a slave of me, but I escaped from them. They were pursuing me, but when I reached this canyon I was safe. In places it is too narrow to admit a mammoth."
"What are you going to do now?"
"Wait until I think they have given up the chase and then return to my own country."
Von Horst suggested that Skruf come to his camp and wait and that then the three of them could go together as far as their trails were identical, but first he wished to bag some game. Skruf offered to help him, and with the latter's knowledge of the quarry it was not long before they had found the sheep and von Horst had killed a young buck. Skruf was greatly impressed and not a little frightened by the report of the pistol and the, to him, miraculous results that von Horst achieved with it.
After skinning the buck and dividing the weight of the carcass between them, they set off for camp, which they reached without serious interruption. Once a bull thag charged them, but they climbed trees and waited until it had gone away, and another time a saber-tooth crossed their path; but his belly was full, and he did not molest them. Thus, through the primitive savagery of Pellucidar, they made their way to the camp.
Dangar was delighted that von Horst had returned safely, for he knew the many dangers that beset a hunter in this fierce world. He was much surprised when he saw Skruf; but when the circumstances were explained to him he agreed to accept the other as a friend, though this relationship with a stranger was as foreign to his code as to Skruf's.
Skruf came from a land called Basti which lay in the same general direction as Sari, though much closer; so it was decided that they would travel together to Skruf's country as soon as Dangar recovered.
