Nu saw that he could not reach the man in time to prevent the blow, but he might distract his attention for the moment that would be required for him to reach his side. From his throat there rose the savage war cry of his long dead people—a cry that brought a hundred jungle creatures to their feet trembling in fear or in rage according to their kind. And it brought Abul Mukarram upstanding too, for in all his life he had never heard the like of that blood-freezing challenge.

At the sight which met his eyes he dropped the girl and darted toward his donkey where hung his long barreled rifle in its boot. Victoria Custer looked, too, and what she saw brought unutterable relief and happiness to her. Then the Arab had turned with levelled gun just as the caveman leaped upon him. There was the report of the firearm ere it was wrenched from Abul Mukarram's grasp and hurled to one side, but the bullet went wide of its mark and the next instant the girl saw the two men locked in what she knew was a death struggle. The Arab struck mighty blows at the head and face of his antagonist, while the caveman, the great muscles rolling beneath his smooth hide, sought for a hold upon the other's throat.

About the two the vicious wolfhound slunk growling with bristling hair, waiting for an opportunity to rush in upon the white robed antagonist of his master. Victoria Custer, her clenched fists tight pressed against her bosom, watched the two men who battled for her. She saw the handsome black head of her savage man bend lower and lower toward the throat of his foeman, and when the strong, white teeth buried themselves in the jugular of the other it was with no sickening qualm of nausea that the girl witnessed the bestial act.

She heard the half wolfish growl of Nu as he tasted the hot, red blood of his enemy. She saw the strong jaws tear and rend the soft flesh of the Arab's throat. She saw the powerful hands bend back the head of the doomed Abul Mukarram. She saw her ferocious mate shake the man as a terrier shakes a rat, and her heart swelled in fierce primitive pride at the prowess of her man.

No longer did Victoria Custer exist. It was Nat-ul, the Savage maiden of the Niocene who, as Nu threw the lifeless corpse of his kill to one side, and opened his arms, flung herself into his embrace. It was Nat-ul, daughter of Tha—Nat-ul of the tribe of Nu that dwelt beyond the Barren Cliffs beside the Restless Sea who threw her arms about her lord and master's neck and drew his mouth down to her hot lips.

It was Nat-ul of the first born who watched Nu and the fierce wolfhound circle about the corpse of the dead Arab. The caveman, moving in the graceful, savage steps of the death dance of his tribe, now bent half over, now leaping high in air, throwing his stone-tipped spear aloft, chanting the weird victory song of a dead and buried age, and beside him his equally savage mate squatted upon her haunches beating time with her slim, white hands.

When the dance was done Nu halted before Nat-ul. The girl rose, facing him and for a long minute the two stood in silence looking at one another. It was the first opportunity that either had had to study the features of the other since the strange miracle that had separated them. Nu found that some subtle change had taken place in his Nat-ul. It was she—of that there could be no doubt; but yet there was that about her which cast a spell of awe over him—she was infinitely finer and more wonderful than he ever had realized.

With the passing of the excitement of the battle and the dance the strange ecstasy which had held the girl in thrall passed slowly away. The rhythm of the dancing of the savage, black-haired giant had touched some chord within her which awoke the long dormant instinct of the primordial. For the time she had been carried back a hundred thousand years to the childhood of the human race—she had not known for those brief instants Victoria Custer, or the twentieth century, or its civilization, for they were yet a thousand centuries in the future.

But now she commenced once more to look through the eyes of generations of culture and refinement. Before her she saw a savage, primitive man. In his eyes was the fire of a great love that would not for long be denied. About her she saw the wild, fierce forest and the cruel jungle, and behind all this, and beyond, her vision wandered to the world she had always known—the world of cities and homes and gentle-folk. She saw her father and her mother and her friends. What would they say?

Again she let her eyes rest upon the man. It was with difficulty that she restrained a mad desire to throw herself upon his broad breast and weep out her doubts and fears close to the beating of his great heart and in the safety of those mighty, protecting arms. But with the wish there arose again the question—what would they say?—held her trembling and frightened from him.
