He faced about and looked up toward the rugged heights above him. He had come a long way to reach his goal, which now lay somewhere just beyond that serrated skyline, and he was of no mind to turn back now in defeat. A day or a week in these rugged mountains might reveal the secret of The Lost Tribe of legend, and surely a month would be sufficient to determine beyond a reasonable doubt that the story had no basis in fact, for von Harben believed that in a month he could fairly well explore such portions of the range as might naturally lend themselves to human habitation, where he hoped at best to find relics of the fabled tribe in the form of ruins or burial mounds. For to a man of von Harben's training and intelligence there could be no thought that The Lost Tribe of legend, if it had ever existed, could be anything more than a vague memory surrounding a few moldy artifacts and some crumbling bones.

It did not take the young man long to reach a decision and presently he turned back to his tent and, entering it, packed a few necessities that had been left to him in a light haversack, strapped his ammunition belt about him, and stepped forth once more to turn his face upward toward the mystery of the Wiramwazi.

In addition to his Luger, von Harben carried a hunting-knife and with this he presently cut a stout staff from one of the small trees that grew sparsely upon the mountainside against the time when he might find an alpenstock indispensable.

A mountain rill furnished him pure, cold water to quench his thirst, and he carried his pistol cocked, hoping that he might bag some small game to satisfy his hunger. Nor had he gone far before a hare broke cover, and as it rolled over to the crack of the Luger, von Harben gave thanks that he had devoted much time to perfecting himself in the use of small arms.

On the spot he built a fire and grilled the hare, after which he lit his pipe and lay at ease while he smoked and planned. His was not a temperament to be depressed or discouraged by seeming reverses, and he was determined not to be hurried by excitement, but to conserve his strength at all times during the strenuous days that he felt must lie ahead of him.

All day he climbed, choosing the long way when it seemed safer, exercising all the lore of mountain-climbing that he had accumulated, and resting often. Night overtook him well up toward the summit of the highest ridge that had been visible from the base of the range. What lay behind, he could not even guess, but experience suggested that he would find other ridges and frowning peaks before him.

He had brought a blanket with him from the last camp and in this he rolled up on the ground. From below there came the noises of the jungle subdued by distance—the yapping of jackals and faintly from afar the roaring of a lion.

Toward morning he was awakened by the scream of a leopard, not from the jungle far below, but somewhere upon the mountain slopes near by. He knew that this savage night prowler constituted a real menace, perhaps the greatest he would have to face, and he regretted the loss of his heavy rifle.

He was not afraid, for he knew that after all there was little likelihood that the leopard was hunting him or that it would attack him, but there was always that chance and so to guard against it he started a fire of dry wood that he had gathered for the purpose the night before. He found the warmth of the blaze welcome, for the night had grown cold, and he sat for some time warming himself.

Once he thought he heard an animal moving in the darkness beyond the range of the firelight, but he saw no shining eyes and the sound was not repeated. And then he must have slept, for the next thing that he knew it was daylight and only embers remained to mark where the beast fire had blazed.
