Presently the darkness lessened and at the final turning of the passage he saw before him an area of moonlight. With renewed hope he sprang rapidly forward and emerged from the mouth of the corridor to find himself in a large circular enclosure the towering white walls of which rose high upon every side--smooth perpendicular walls upon the sheer face of which was no slightest foothold. To his left lay a pool of water, one side of which lapped the foot of the wall at this point. It was, doubtless, the wallow and the drinking pool of the GRYF. And now the creature emerged from the corridor and Tarzan retreated to the edge of the pool to make his last stand. There was no staff with which to enforce the authority of his voice, but yet he made his stand for there seemed naught else to do. Just beyond the entrance to the corridor the GRYF paused, turning its weak eyes in all directions as though searching for its prey. This then seemed the psychological moment for his attempt and raising his voice in peremptory command the ape-man voiced the weird whee-oo! of the Tor-o-don. Its effect upon the GRYF was instantaneous and complete--with a terrific bellow it lowered its three horns and dashed madly in the direction of the sound. To right nor to left was any avenue of escape, for behind him lay the placid waters of the pool, while down upon him from before thundered annihilation. The mighty body seemed already to tower above him as the ape-man turned and dove into the dark waters. Dead in her breast lay hope. Battling for life during harrowing months of imprisonment and danger and hardship it had fitfully flickered and flamed only to sink after each renewal to smaller proportions than before and now it had died out entirely leaving only cold, charred embers that Jane Clayton knew would never again be rekindled. Hope was dead as she faced Lu-don, the high priest, in her prison quarters in the Temple of the Gryf at A-lur. Both time and hardship had failed to leave their impress upon her physical beauty--the contours of her perfect form, the glory of her radiant loveliness had defied them, yet to these very attributes she owed the danger which now confronted her, for Lu-don desired her. From the lesser priests she had been safe, but from Lu-don, she was not safe, for Lu-don was not as they, since the high priestship of Pal-ul-don may descend from father to son.
