“I do not know you,” he said, “but I believe that I may trust you, since after all blood ties are strong, and we are the only men of our race in this valley. You might gain something in favor by betraying me, but I cannot believe that you will do it.”
“Do not fear,” said the old man, “I hate them. If I could help you I would, but I know that there is no hope of success for whatever plan you may have in mind—the woman will never be rescued; you will never leave the Valley of the Palace of Diamonds—you will never leave the palace itself unless the Bolgani wish it.”
The ape-man grinned. “You have been here so long,” he said, “that you are beginning to assume the attitude of mind that keeps the Gomangani in perpetual slavery. If you want to escape, come with me. We may not succeed, but at least you will have a better chance if you try than as if you remained forever in this tower.”
The old man shook his head. “No,” he said, “it is hopeless. If escape had been possible I should have been away from here long ago.”
“Goodbye then,” said Tarzan, and swinging out of the window he clambered toward the roof below, along the stout stem of the old ivy.
The old man watched him for a moment until he saw him make his way carefully across the roof toward the flat-topped tower where he hoped to find and liberate La. Then the old fellow turned and hurried rapidly down the crude stairway that rose ladder-like to the center of the tower.
Tarzan made his way across the uneven roof of the main building, clambering up the sides of its higher elevations and dropping again to its lower levels as he covered a considerable distance between the east tower and that flat-topped structure of peculiar design in which La was supposed to be incarcerated. His progress was slow, for he moved with the caution of a beast of prey, stopping often in dense shadows to listen.
When at last he reached the tower, he found that it had many openings letting upon the roof—openings which were closed only with hangings of the heavy tapestried stuff which he had seen in the tower. Drawing one of these slightly aside he looked within upon a large chamber, bare of furnishings, from the center of which there protruded through a circular aperture the top of a stairway similar to that he had ascended in the east tower. There was no one in sight within the chamber, and Tarzan crossed immediately to the stairway. Peering cautiously into the opening Tarzan saw that the stairway descended for a great distance, passing many floors. How far it went he could not judge, except it seemed likely that it pierced subterranean chambers beneath the palace. Sounds of life came up to him through the shaft, and odors, too, but the latter largely nullified, in so far as the scent impressions which they offered Tarzan were concerned, by the heavy incense which pervaded the entire palace.
It was this perfume that was to prove the ape-man’s undoing, for otherwise his keen nostrils would have detected the scent of a nearby Gomangani. The fellow lay behind one of the hangings at an aperture in the tower wall. He had been lying in such a position that he had seen Tarzan enter the chamber, and he was watching him now as the ape-man stood looking down the shaft of the stairway. The eyes of the black had at first gone wide in terror at sight of this strange apparition, the like of which he had never seen before. Had the creature been of sufficient intelligence to harbor superstition, he would have thought Tarzan a god descended from above. But being of too low an order to possess any imagination whatsoever, he merely knew that he saw a strange creature, and that all strange creatures must be enemies, he was convinced. His duty was to apprise his masters of this presence in the palace, but he did not dare to move until the apparition had reached a sufficient distance from him to insure that the movements of the Gomangani would not be noticed by the intruder—he did not care to call attention to himself, for he had found that the more one effaced oneself in the presence of the Bolgani, the less one was likely to suffer. For a long time the stranger peered down the shaft of the stairway, and for a long time the Gomangani lay quietly watching him. But at last the former descended the stairs and passed out of sight of the watcher, who immediately leaped to his feet and scurried away across the roof of the palace toward a large tower arising at its western end.
As Tarzan descended the ladder the fumes of the incense became more and more annoying. Where otherwise he might have investigated quickly by scent he was now compelled to listen for every sound, and in many cases to investigate the chambers opening upon the central corridor by entering them. Where the doors were locked, he lay flat and listened close to the aperture at their base. On several occasions he risked calling La by name, but in no case did he receive any reply.
He had investigated four landings and was descending to the fifth when he saw standing in one of the doorways upon this level an evidently much excited and possibly terrified black. The fellow was of giant proportions
