"El Adrea has been here. From the signs, though, I rather think that his prey escaped him. With a little start they would be safe enough from him in the open." There was nothing to do but continue on foot. The way led them across a low spur of the mountains, but the girl knew the trail as well as she did her mother's face. They walked in easy, swinging strides, Tarzan keeping a hand's breadth behind the girl's shoulder, that she might set the pace, and thus be less fatigued. As they walked they talked, occasionally stopping to listen for sounds of pursuit.
It was now a beautiful, moonlit night. The air was crisp and invigorating. Behind them lay the interminable vista of the desert, dotted here and there with an occasional oasis. The date palms of the little fertile spot they had just left, and the circle of goatskin tents, stood out in sharp relief against the yellow sand—a phantom paradise upon a phantom sea. Before them rose the grim and silent mountains. Tarzan's blood leaped in his veins.
This was life! He looked down upon the girl beside him—a daughter of the desert walking across the face of a dead world with a son of the jungle. He smiled at the thought. He wished that he had had a sister, and that she had been like this girl. What a bully chum she would have been! They had entered the mountains now, and were progressing more slowly, for the trail was steeper and very rocky.
For a few minutes they had been silent. The girl was wondering if they would reach her father's douar before the pursuit had overtaken them. Tarzan was wishing that they might walk on thus forever. If the girl were only a man they might. He longed for a friend who loved the same wild life that he loved. He had learned to crave companionship, but it was his misfortune that most of the men he knew preferred immaculate linen and their clubs to nakedness and the jungle. It was, of course, difficult to understand, yet it was very evident that they did.
The two had just turned a projecting rock around which the trail ran when they were brought to a sudden stop. There, before them, directly in the middle of the path, stood Numa, El Adrea, the black lion. His green eyes looked very wicked, and he bared his teeth, and lashed his bay-black sides with his angry tail. Then he roared—the fearsome, terror-inspiring roar of the hungry lion which is also angry.
"Your knife," said Tarzan to the girl, extending his hand. She slipped the hilt of the weapon into his waiting palm. As his fingers closed upon it he drew her back and pushed her behind him. "Walk back to the desert as rapidly as you can. If you hear me call you will know that all is well, and you may return."
"It is useless," she replied, resignedly. "This is the end."
"Do as I tell you," he commanded. "Quickly! He is about to charge." The girl dropped back a few paces, where she stood watching for the terrible sight that she knew she should soon witness.
The lion was advancing slowly toward Tarzan, his nose to the ground, like a challenging bull, his tail extended now and quivering as though with intense excitement.
The ape-man stood, half crouching, the long Arab knife glistening in the moonlight. Behind him the tense figure of the girl, motionless as a carven statue. She leaned slightly forward, her lips parted, her eyes wide. Her only conscious thought was wonder at the bravery of the man who dared face with a puny knife the lord with the large head. A man of her own blood would have knelt in prayer and gone down beneath those awful fangs without resistance. In either case the result would be the same—it was inevitable; but she could not repress a thrill of admiration as her eyes rested upon the heroic figure before her. Not a tremor in the whole giant frame—his attitude as menacing and defiant as that of El Adrea himself.
The lion was quite close to him now—but a few paces intervened —he crouched, and then, with a deafening roar, he sprang.
Chapter XI.

As Numa El Adrea launched himself with widespread paws and bared fangs he looked to find this puny man as easy prey as the score who had gone down beneath him in the past. To him man was a clumsy, slow-moving, defenseless creature—he had little respect for him.
But this time he found that he was pitted against a creature as agile and as quick as himself. When his mighty frame struck the spot where the man had been he was no longer there.
The watching girl was transfixed by astonishment at the ease with which the crouching man eluded the great paws. And now, O Allah! He had rushed in behind El Adrea's shoulder even before the beast could turn, and had grasped him by the mane. The lion reared upon his hind legs like a horse— Tarzan had known that he would do this, and he was ready. A giant arm encircled the black-maned throat, and once, twice, a dozen times a sharp blade darted in and out of the bay-black side behind the left shoulder.
Frantic were the leaps of Numa—awful his roars of rage and pain; but the giant upon his back could not be dislodged or brought within reach of fangs or talons in the brief interval of life that remained to the lord with the large head. He was quite dead when Tarzan of the Apes released his hold and arose. Then the daughter of the desert witnessed a thing that terrified her even more than had the presence of El Adrea. The man placed a foot upon the carcass of his kill, and, with his handsome face raised toward the full moon, gave voice to the most frightful cry that ever had smote upon her ears.
With a little cry of fear she shrank away from him—she thought that the fearful strain of the encounter had driven him mad. As the last note of that fiendish challenge died out in the diminishing echoes of the distance the man dropped his eyes until they rested upon the girl.
Instantly his face was lighted by the kindly smile that was ample assurance of his sanity, and the girl breathed freely once again, smiling in response.
"What manner of man are you?" she asked. "The thing you have done is unheard of. Even now I cannot believe that it is possible for a lone man armed only with a knife to have fought hand to hand with El Adrea and conquered him, unscathed—to have conquered him at all. And that cry —it was not human. Why did you do that?" Tarzan flushed. "It is because I forget," he said, "sometimes, that I am a civilized man. When I kill it must be that I am another creature." He did not try to explain further, for it always seemed to him that a woman must look with loathing upon one who was yet so nearly a beast.
Together they continued their journey. The sun was an hour high when they came out into the desert again beyond the mountains.
Beside a little rivulet they found the girl's horses grazing. They had come this far on their way home, and with the cause of their fear no longer present had stopped to feed.
With little trouble Tarzan and the girl caught them, and, mounting, rode out into the desert toward the douar of Sheik Kadour ben Saden.
No sign of pursuit developed, and they came in safety about nine o'clock to their destination. The sheik had but just returned.
He was frantic with grief at the absence of his daughter, whom he thought had been again abducted by the marauders. With fifty men he was already mounted to go in search of her when the two rode into the douar.
His joy at the safe return of his daughter was only equaled by his gratitude to Tarzan for bringing her safely to him through the dangers of the night, and his thankfulness that she had been in time to save the man who had once saved her.
No honor that Kadour ben Saden could heap upon the ape-man in acknowledgment of his esteem and friendship was neglected. When the girl had recited the story of the slaying of El Adrea Tarzan was surrounded by a mob of worshiping Arabs—it was a sure road to their admiration and respect.
The old sheik insisted that Tarzan remain indefinitely as his guest. He even wished to adopt him as a member of the tribe,
