"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 center 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. Athne, the city of ivory, is the city from which I come. The men of Cathne, in the valley of Onthar, are the enemies of my people."
"Tomorrow, then," said Tarzan, "we shall set out for the city of Athne in the valley of Thenar."
As Tarzan and Valthor ate meat that they had cut from yesterday's kill and carried with them, many weary miles to the south a black-maned lion lashed his tail angrily and voiced a savage growl as he stood over the body of a buffalo calf he had killed and faced an angry bull pawing the earth and bellowing a few yards away.
Rare is the beast that will face Gorgo, the buffalo, when rage inflames his red-rimmed eyes; but the great lion showed no intention of leaving its prey even in the face of the bull's threatened charge. He stood his ground. The roars of the lion and the bull mingled in a savage, thunderous dissonance that shook the ground, stilling the voices of the lesser people of the jungle.
Gorgo gored the earth, working himself into a frenzy of rage. Behind him, bellowing, stood the mother of the slain calf. Perhaps she was urging her lord and master to avenge the murder. The other members of the herd had bolted into the thickest of the jungle leaving these two to contest with Numa his right to his kill, leaving vengeance to those powerful horns backed by that massive neck.
With a celerity and agility that belied his great weight, the bull charged. That two such huge beasts could move so quickly and so lightly seemed incredible, as it seemed incredible that any creature could either withstand or avoid the menace of those mighty horns; but the lion was ready, and as the bull was almost upon him, he leaped to one side, reared upon his hind feet and with one massive, taloned paw struck the bull a terrific blow on the side of its head that wheeled it half around and sent it stumbling to its knees, half stunned and bleeding, its great jawbone crushed and splintered. And before Gorgo could regain his feet, Numa leaped full upon his back, buried his teeth in the bulging muscles of the great neck, and with one paw reached for the nose of the bellowing bull, jerking the head back with a mighty surge that snapped the vertebrae.
Instantly the lion was on his feet again facing the cow, but she did not charge. Instead, bellowing, she crashed away into the jungle leaving the king of beasts standing with his forefeet upon his latest kill.
That night Numa fed well; but when he had gorged himself he did not lie up as a lion should, but continued toward the north along the mysterious trail he had been following for many days.
