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.

Von Horst could not understand how these men knew in what direction their countries lay when there were no means of determining the points of the compass, nor could they explain the phenomenon to him. They merely pointed to their respective countries, and they pointed in the same general direction. How far they were from home neither knew; but by comparing notes, they were able to assume that Sari lay very much farther away than Basti. What von Horst had not yet discovered was that each possessed, in common with all other inhabitants of Pellucidar, a well developed homing instinct identical with that of most birds and which is particularly apparent in carrier pigeons.

As sleeps came and went and hunting excursions were made necessary to replenish their larder, Skruf grew more and more impatient of the delay. He was anxious to return to his own country, but he realized the greater safety of numbers and especially that of the protection of von Horst's miraculous weapon that killed so easily at considerable distances. He often questioned Dangar in an effort to ascertain if there was any change in his condition, and he was never at any pains to conceal his disappointment when the Sarian admitted that he still had no feeling below his neck.

On one occasion when von Horst and Skruf had gone farther afield than usual to hunt, the latter broached the subject of his desire to return to his own country; and the man of the outer crust learned for the first time the urge that prompted the other's impatience.

"I have chosen my mate," explained Skruf, "but she demanded the head of a tarag to prove that I am a brave man and a great hunter. It was while I was hunting the tarag that the Mammoth Men captured me. The girl has slept many times since I went away. If I do not return soon some other warrior may bring the head of a tarag and place it before the entrance to her cave; then, when I return, I shall have to find another who will mate with me."

"There is nothing to prevent your returning to your own country whenever you see fit," von Horst assured him.

"Could you kill a tarag with that little thing that makes such a sharp noise?" inquired Skruf.

"I might." Von Horst was not so certain of this; at least he was not certain that he could kill one of the mighty tigers quickly enough to escape death from its formidable fangs and powerful talons before it succumbed.

"The way we have come today," remarked Skruf, tentatively, "is in the direction of my country. Let us continue on."

"And leave Dangar?" asked von Horst.

Skruf shrugged. "He will never recover. We cannot remain with him forever. If you will come with me, you can easily kill a tarag with the thing you call pistol; then I will place it before the entrance to the girl's cave, and she will think that I killed it. In return, I will see that the tribe accepts you. They will not kill you. You may live with us and be a Bastian. You can take a mate, too; and there are many beautiful girls in Basti."

"Thanks," replied von Horst; "but I shall remain with Dangar. It will not be long now before he recovers. I am sure that the effects of the poison will disappear as they did in my case. The reason that they have persisted so much longer is that he must have received a much larger dose than I."

"If he dies, will you come with me?" demanded Skruf.

Von Horst did not like the expression in the man's eyes as he asked the question. He had never found Skruf as companionable as Dangar. His manner was not as frank and open. Now he was vaguely suspicious of his intentions and his honesty, although he realized that he had nothing tangible upon which to base such a judgment and might be doing the man an injustice. However, he phrased his reply to Skruf's question so that he would be on the safe side and not be placing a premium on Dangar's life. "If he lives," he said, "we will both go with you when he recovers." Then he turned back toward the camp.

Time passed. How much, von Horst could not even guess. He had attempted to measure it once, keeping his watch wound and checking off the lapse of days on a notched stick; but where it is always noon it is not always easy to remember either to wind or consult a watch. Often he found that it had run down; and then, of course, he never knew how long it had been stopped before he discovered that it was not running; nor, when he slept, did he ever know for how long a time. So presently he became discouraged; or, rather, he lost interest. What difference did the duration of time make, anyway? Had not the inhabitants of Pellucidar evidently existed quite as contentedly without it as they would have with? Doubtless they had been more contented.
