Chapter 15

As the British plane piloted by Lieutenant Harold Percy Smith-Oldwick rose above the jungle wilderness where Bertha Kircher's life had so often been upon the point of extinction, and sped toward the east, the girl felt a sudden contraction of the muscles of her throat. She tried very hard to swallow something that was not there. It seemed strange to her that she should feel regret in leaving behind her such hideous perils, and yet it was plain to her that such was the fact, for she was also leaving behind something beside the dangers that had menaced her -- a unique figure that had entered her life, and for which she felt an unaccountable attraction .

Before her in the pilot's seat sat an English officer and gentleman whom, she knew, loved her, and yet she dared to feel regret in his company at leaving the stamping ground of a wild beast!

Lieutenant Smith-Oldwick, on his part, was in the seventh heaven of elation. He was in possession again of his beloved ship, he was flying swiftly in the direction of his comrades and his duty, and with him was the woman he loved. The fly in the ointment, however, was the accusation Tarzan had made against this woman.

He tried to convince himself that Tarzan was mistaken, and when he conjured upon the screen of recollection the face of the girl behind him, he was doubly reassured that those lines of sweet femininity and character, those clear and honest eyes, could not belong to one of the hated alien race.

And so they sped toward the east, each wrapped in his own thoughts. Below them they saw the dense vegetation of the jungle give place to the scantier growth upon the hillside, and then before them there spread the wide expanse of arid wastelands marked by the deep scarring of the narrow gorges that long-gone rivers had cut there in some forgotten age.

Shortly after they passed the summit of the ridge which formed the boundary between the desert and the fertile country , Ska, the vulture, winging his way at a high altitude toward his aerie, caught sight of a strange new bird of gigantic proportions encroaching upon the preserves of his aerial domain. Whether with intent to give battle to the interloper or merely impelled by curiosity, Ska rose suddenly upward to meet the plane. Doubtless he misjudged the speed of the newcomer, but be
