To elude the creature, then, upon the possibility of discovering some loophole of escape from his predicament seemed to the ape-man the wisest course to pursue. Too much was at stake to risk an encounter that might be avoided--an encounter the outcome of which there was every reason to apprehend would seal the fate of the mate that he had just found, only to lose again so harrowingly. Yet high as his disappointment and chagrin ran, hopeless as his present estate now appeared, there tingled in the veins of the savage lord a warm glow of thanksgiving and elation. She lived! After all these weary months of hopelessness and fear he had found her. She lived! To the opposite side of the chamber, silently as the wraith of a disembodied soul, the swift jungle creature moved from the path of the charging Titan that, guided solely in the semi-darkness by its keen ears, bore down upon the spot toward which Tarzan's noisy entrance into its lair had attracted it. Along the further wall the ape-man hurried. Before him now appeared the black opening of the corridor from which the beast had emerged into the larger chamber. Without hesitation Tarzan plunged into it. Even here his eyes, long accustomed to darkness that would have seemed total to you or to me, saw dimly the floor and the walls within a radius of a few feet--enough at least to prevent him plunging into any unguessed abyss, or dashing himself upon solid rock at a sudden turning. The corridor was both wide and lofty, which indeed it must be to accommodate the colossal proportions of the creature whose habitat it was, and so Tarzan encountered no difficulty in moving with reasonable speed along its winding trail. He was aware as he proceeded that the trend of the passage was downward, though not steeply, but it seemed interminable and he wondered to what distant subterranean lair it might lead. There was a feeling that perhaps after all he might better have remained in the larger chamber and risked all on the chance of subduing the GRYF where there was at least sufficient room and light to lend to the experiment some slight chance of success. To be overtaken here in the narrow confines of the black corridor where he was assured the GRYF could not see him at all would spell almost certain death and now he heard the thing approaching from behind. Its thunderous bellows fairly shook the cliff from which the cavernous chambers were excavated. To halt and meet this monstrous incarnation of fury with a futile whee-oo! seemed to Tarzan the height of insanity and so he continued along the corridor, increasing his pace as he realized that the GRYF was overhauling him.
