As Tarzan watched with interest the scene below him, two Bolgani emerged from the main entrance, a huge portal, some thirty feet in width, and perhaps fifteen feet high. The two wore headbands, supporting tall, white feathers. As they emerged they took post on either side of the entrance, and cupping their hands before their mouths gave voice to a series of shrill cries that bore a marked resemblance to trumpet calls. Immediately the blacks ceased work and hastened to the foot of the stairs descending from the terrace to the garden. Here they formed lines on either side of the stairway, and similarly the Bolgani formed two lines upon the terrace from the main portal to the stairway, forming a living aisle from one to the other. Presently from the interior of the building came other trumpet-like calls, and a moment later Tarzan saw the head of a procession emerging. First came four Bolgani abreast, each bedecked with an ornate feather headdress, and each carrying a huge bludgeon erect before him. Behind these came two trumpeters, and twenty feet behind the trumpeters paced a huge, black-maned lion, held in leash by four sturdy blacks, two upon either side, holding what appeared to be golden chains that ran to a scintillant diamond collar about the beast’s neck. Behind the lion marched twenty more Bolgani, four abreast. These carried spears, but whether they were for the purpose of protecting the lion from the people or the people from the lion Tarzan was at a loss to know.
The attitude of the Bolgani lining either side of the way between the portal and the stairway indicated extreme deference, for they bent their bodies from their waists in a profound bow while Numa was passing between their lines. When the beast reached the top of the stairway the procession halted, and immediately the Gomangani ranged below prostrated themselves and placed their foreheads on the ground. Numa, who was evidently an old lion, stood with lordly mien surveying the prostrate humans before him. His evil eyes glared glassily, the while he bared his tusks in a savage grimace, and from his deep lungs rumbled forth an ominous roar, at the sound of which the Gomangani trembled in unfeigned terror. The ape-man knit his brows in thought. Never before had he been called upon to witness so remarkable a scene of the abasement of man before a beast. Presently the procession continued upon its way descending the staircase and turning to the right along a path through the garden, and when it had passed them the Gomangani and the Bolgani arose and resumed their interrupted duties.
Tarzan remained in his concealment watching them, trying to discover some explanation for the strange, paradoxical conditions that he had witnessed. The lion, with his retinue, had turned the far corner of the palace and disappeared from sight. What was he to these people, to these strange creatures? What did he represent? Why this topsy-turvy arrangement of species? Here man ranked lower than the half-beast, and above all, from the deference that had been accorded him, stood a true beast—a savage carnivore.
He had been occupied with his thoughts and his observations for some fifteen minutes following the disappearance of Numa around the eastern end of the palace, when his attention was attracted to the opposite end of the structure by the sound of other shrill trumpet calls. Turning his eyes in that direction, he saw the procession emerging again into view, and proceeding toward the staircase down which they had entered the garden. Immediately the notes of the shrill call sounded upon their ears the Gomangani and the Bolgani resumed their original positions from below the foot of the staircase to the entrance to the palace, and once again was homage paid to Numa as he made his triumphal entry into the building.
Tarzan of the Apes ran his fingers through his mass of tousled hair, but finally he was forced to shake his head in defeat—he could find no explanation whatsoever for all that he had witnessed. His curiosity, however, was so keenly piqued that he determined to investigate the palace and surrounding grounds further before continuing on his way in search of a trail out of the valley.
Leaving the body of Bolgani where he had cached it, he started slowly to circle the building that he might examine it from all sides from the concealing foliage of the surrounding forest. He found the architecture equally unique upon all sides, and that the garden extended entirely around the building, though a portion upon the south side of the palace was given over to corrals and pens in which were kept numerous goats and a considerable flock of chickens. Upon this side, also, were several hundred swinging, beehive huts, such as he had seen in the native village of the Gomangani. These he took to be the quarters of the black slaves, who performed all the arduous and menial labor connected with the palace.
The lofty granite wall which surrounded the entire enclosure was pierced by but a single gate which opened opposite the east end of the palace. This gate was large and of massive construction, appearing to have been built to withstand the assault of numerous and well-armed forces. So strong did it appear that the ape-man could not but harbor the opinion that it had been constructed to protect the interior against forces equipped with heavy battering rams. That such a force had ever existed within the vicinity in historic times seemed most unlikely, and Tarzan conjectured, therefore, that the wall and the gate were of almost unthinkable antiquity, dating, doubtless, from the forgotten age of the Atlantians, and constructed, perhaps, to protect the builders of the Palace of Diamonds from the well-armed forces that had come from Atlantis to work the gold
