Now Sheeta stood trembling upon uncertain feet as once again the knife was plunged deeply into his side; then, his great voice forever stilled, he sank lifeless to the ground as the ape-man rolled from beneath him and sprang to his feet.

The man whose life Tarzan had saved came forward and laid a hand upon the shoulder of the ape-man, speaking a few words in a low voice but in the tongue that Tarzan did not understand, though he guessed that it expressed the gratitude that the manner of the man betokened.

Influenced by the attack of the panther and knowinz that Numa was abroad, Tarzan, by signs, persuaded the man to come up into the tree. Here the ape-man helped him construct a nest similar to his own. For the balance of the night they slept in peace, and the sun was an hour old before either stirred the following morning. Then the ape-man rose and stretched himself.

Nearby, the other man sat up and looked about him. His eyes met Tarzan's, and he smiled and nodded.

The wild beast in Tarzan looked into the brown eyes of the stranger and was satisfied that here was one who must be trusted; the man in him noted the headband that confined the black hair, saw the strangely wrought ivory ornament in the centre of the forehead, the habergeon that he was now donning, the ivory ornaments on wrists and ankles, and found his curiosity piqued.

The ivory ornament in the centre of the headband was shaped like a concave, curved trowel, the point of which projected above the top of the man's head and curved forward. His wristlets and anklets were of long flat strips of ivory laid close together and fastened around the limbs by leather thongs that were laced through holes piercing the strips near their tops and bottoms. His sandals were of heavy leather, apparently elephant hide, and were supported by leather thongs fastened to the bottoms of his anklets.

That all these trappings were solely for purposes of ornamentation Tarzan did not believe. He saw that almost without exception they would serve as a protection against a cutting weapon such as a sword or battle-axe.

But speculation concerning this matter was relegated to the background of his thoughts by hunger and recollection of the remains of yesterday's kill that he had hung high in a tree of the forest farther up the river. He dropped lightly to the ground, motioning the young warrior to follow him, and set off in the direction of his cache, keeping his keen senses always on the alert for enemies.

Cleverly hidden by leafy branches, the meat was intact when Tarzan reached it. He cut several strips and tossed them down to the warrior waiting on the ground below; then he cut some for himself and crouching in a crotch proceeded to eat it raw. His companion watched him for a moment in surprise: then he made fire with a bit of steel and flint and cooked his own portion.

As he ate, Tarzan's active mind was considering plans for the future. He had come to Abyssinia for a specific purpose, thouzh the matter was not of such immediate importance that it demanded instant attention. In fact, in the philosophy that a lifetime of primitive environment had inspired, time was not an important consideration.

The phenomenon of this ivory-armoured warrior aroused questions that intrigued his interest to a far greater extent than did the problems that had brought him thus far from his own stamping grounds, and he decided that the latter should wait the solving of the riddle that his new-made acquaintance presented.

Having no other means of communication than signs rendered an exchange of ideas between the two difficult, but when they had finished their meal and Tarzan had descended to the ground, he succeeded in asking his companion in what direction he wished to go. The warrior pointed in a north-easterly direction toward the high mountains, and, as plainly as he could through the medium of signs, invited Tarzan to accompany him to his country. This invitation Tarzan accepted and motioned the other to lead the way.

For days that stretched to weeks the two men struck deeper and deeper into the heart of a stupendous mountain system. Always mentally alert and eager to learn, Tarzan took advantage of the opportunity to learn the language of his companion, and he proved such an apt pupil that they were soon able to make themselves understood by one another.

Among the first things that Tarzan learned was that his companion's name was Valthor, while Valthor took the earliest opportunity to evince an interest in the ape-man's weapons. As he was unarmed, Tarzan spent a day in making a spear and bow and arrows for him. Thereafter, as Valthor taught the Lord of the Jungle to speak his language, Tarzan instructed the former in the use of the bow, the spear being already a familiar weapon to the young warrior.

Thus the days and the weeks passed and the two seemed no nearer the country of Valthor than when they had started from the vicinity of the camp of the Shiftas. Tarzan found game of certain varieties plentiful in the mountains. He hunted, and enjoyed the beauties of unspoiled nature, practically oblivious of the passage of time.

But Valthor was less patient, and at last, late one day when they found themselves at the head of a blind canyon where stupendous cliffs barred further progress, he admitted defeat. "I am lost," he said simply.

"That," remarked Tarzan, "I could have told you many days ago."

Valthor looked at him in surprise. "How could you know that," he demanded, "when you yourself do not know in what direction my country lies?"

"I know," replied the ape-man, "because during the past week you have led the way toward the four points of the compass, and today we are within five miles of where we were a week ago. Across this ridge at our right, not more than five miles away, is the little stream where I killed the ibex, and the gnarled old tree in which we slept that night just seven suns ago."

Valthor scratched his head in perplexity, and then he smiled. "I cannot dispute you," he admitted. "Perhaps you are right, but what are we going to do?"

"Do you know in what direction your country lies from the camp in which I found you?" asked Tarzan.

"The valley of Thenar is due east of that point," replied Valthor; "of that I am positive."

"Then we are directly southwest of it now, for we have travelled a considerable distance toward the south since we entered the higher mountains. If your country lies in these mountains, then it should not be difficult to find it if we can keep moving always in a northeasterly direction."

"This jumble of mountains with their twisting canyons and gorges confuses me," Valthor admitted. "You see, in all my life before, I have never been farther from Ihenar than the valley of Onthar, and beth these valleys are urrounded by landmarks with which I am so familiar that I need no other guides. It has never been necessary for me to consult the positions of the sun, the moon, nor the stars before, and so they have been of no help to me since we set out in search of Thenar. Do you believe that you could hold a course toward the northeast in this maze of mountains? If you can, then you had better lead the way rather than I."

"I can go toward the northeast," Tarzan assured him "but I cannot find your country unless it lies in my path."

"If we reach a point within fifty or a hundred miles of it, from some high eminence we shall see Xarator," explained Valthor, "and then I shall know my way to Thenar, for Xarator is almost due west of Athne."

"What are Xarator and Athne?" demanded Tarzan.

"Xarator is a great peak, the centre of which is filled with fire and molten rock. It lies at the north end of the valley of Onthar and belongs to the men of Cathne, the city of gold.
