The next instant, the stillness of the night was hurled aside by a howling, gurgling shout from a hundred, a thousand hysterically distended ape throats. With the sickening sound came from the village the sullen roaring of drums.

Ten minutes later, a Kirby who was cold with apprehension and wonder looked down from his leaf-crowned height at such a spectacle as he knew human eyes had never before seen. The shouting had died away, the drums were silenced. Crammed into the clearing, their foul, hairy bodies packed close together, the silver light glinting against rolling red eyes and grinning white teeth, stood fully a thousand apes!

Once the first tumult of shouting in the village had died, they had come on in silence, and in orderly procession. Those who bore the drums--huge gourds with heads of stretched skin--had formed a line entirely around the outer diameter of the circular clearing. Then others, lugging vats of a dark, heady-smelling liquor, had deposited their burden beside the drums, and formed a second circle. The balance of the thousand had crowded itself together as best it might, leaving bare the center of the clearing with its black hole and fangs of poles.

Kirby, looking down at these legions, did not wonder that cold sweat wetted his back.

Capable of thinking about only one thing--Naida--he was trying with all his strength not to think. Ivana, her face blanched in the light which filtered their camouflage of leaves, sat rigid, her hands locked about her cold rifle. On the branch above, Nini and Gori were as still as mummies. No one had spoken since the vanguard of apes had appeared.

But at last Nini leaned close to Kirby.

"Have you any idea of what all this means?"

A draught of hot night air carried up a stench of drunkenness, and the goaty odor of ma.s.sed animal bodies.

"No," Kirby whispered. "I suppose, from Gori's having brought us here, that Naida is going to appear somehow. We've simply got to trust that Gori knows what she is about."

"But listen--" Ivana suppressed a shudder. "Suppose they should bring Naida here presently to force her to take part in some ceremony at which we can only guess. Gori, who thinks we can work miracles, supposes we can rescue Naida. But I--I'm not so certain. Is there _anything_ we can do?"

It was exactly that question which had made Kirby fight to keep himself from thinking. His face turned gray before he answered. But answer he did, finally.

"Yes, there is one thing we can do, Ivana. We've got to be frank with each other, and so far, this is the _only_ thing I've been able to figure out. If Naida is brought here, and they make any move to harm her or torture her, we can, and we will, shoot her quickly, before harm or pain comes."

A grim silence settled once more. During the last miles of march in the jungle, there had persisted in Kirby's heart the hope that there would be at least _something_ favorable in whatever situation they might encounter. His spirits were so low now that he dared not speak again.

Amongst the noiseless sea of ape-men below them came, every now and again, a little ripple of motion as some anthropoid shadow fell out of his place, approached the liquor vats, and swilled down the black brew, a quart at a gulp. But mostly there was little commotion. Ivana drew a sibilant breath and said that she wished something would happen.

"I wish," Kirby answered tensely, "that we knew _what_ is going to happen."

But the nightmare waiting was not to go on forever. Kirby leaned forward and pointed.

It was only instinct that had made him know action must come. For a second, no change in the expression of the ape-men, no movement in their crammed ranks, was visible. Then, however, a queer, subdued grunting rumbled deep down in many throats, and those who had faced the hundred-foot s.p.a.ce in the center of the clearing squatted down on their hams.

In the back of the crowd necks were craned. The stronger shoved the weaker in an effort to get a better view of the cleared stage, and a few ape-men who had been drinking hurried on unsteady legs to their places.

"The drums!" Kirby whispered then.

With almost military precision, the scores of leather-faced creatures who had led the procession into the clearing, clasped the skin-headed gourds to their s.h.a.ggy bellies, and stood with free arm raised as though awaiting a signal. Nini moved in her position, and Kirby felt Ivana shiver and edge close to him.

From the front rank of the crowd, there sprang up a great male creature with the face of a gargoyle and the body of a jungle giant. Just once he reeled on his feet, as though black alcohol had befuddled him, then he steadied himself, flung both arms above his head, and rolled out a command which burst upon Kirby's ears like thunder.

It was as if the whole cavern of the lower world, and the whole of the round earth itself, had been rocked uneasily, dreadfully by the bellowing, crashing explosion of the drums. Maddened by the turmoil he had let loose, the gargoyle-faced giant ape-man leered about him with blood-shot, drunken eyes, and beat on his cicatrized chest with ma.s.sive fists. Suddenly he let out a bellow. Straight up into the air he sprang in a wild leap. When he came down, he was dancing, and the portentious, the sickeningly mysterious ceremony for which such solemn preparation had been made, was begun.

Kirby drew a rasping breath. Knowing that there must be some definite reason for the dance having begun just when and as it had, he looked beyond the solitary dancing giant, on beyond the crowded legions of the apes, toward the village. There, where the main trail from the community approached the clearing, he saw precisely the thing which he had both hoped desperately and dreaded terribly to find.

Headed directly toward the clearing, moving down the trail with slow, majestic pace, came a procession headed by a bodyguard of ape-men and augmented by other men whose nakedness was covered by unmistakable, unforgetable priestly robes of gray.

All at once the ape-people in the clearing began to scuffle apart, opening a lane down which the procession might pa.s.s to the central stage with its dancer, its ink spot orifice, and its fangs of tall poles. Kirby, watching the congregation, watching the majestic approach of gray robes through the night, wiped away from his forehead a sweat of fear.

"I think," Nini called in a voice pitched high to outsound the drums, "that the--the Duca is with them!"

"Yes." Kirby pointed jerkily. "In the middle of the procession, there, surrounded by his caciques!"

The Duca!

Yet his approach did not hold Kirby. Directly behind the priests were emerging now from the jungle a new company of ape-men. Squinting his eyes, Kirby saw that two of them were lugging on a pole across their shoulders a curious burden--a sort of monstrous bird cage of barked withes. Crouched on the floor of the cage in a little motionless, white heap--

But Kirby closed his eyes. Ivana, cowering against him, gulped as though she were going to be sick. Nini leaned down from above and looked at them with dilated eyes. Although none of them spoke, all knew that they had found Naida at last.

Kirby was the first to pull himself up. Opening his eyes, he stared long at the white gowned, motionless shape within the cage. Next summing up the whole situation--the cage surrounded by an armed band, the clearing crammed with a thousand ape-men--he shook his head. Afterward, he made a quick movement with his hands.

Ivana, seeing that movement, seeing the expression on his face, started out of her daze.

"No! No! Oh, there must be some other way out for her! There must--"

Her cry, half a shriek, did not change Kirby's look. What he had done with his hands was to throw a sh.e.l.l into the chamber of his rifle. Now he held the rifle grimly, ready to carry it to his shoulder.

The procession with the bodyguard of ape-men at its head, the renegade Duca and his caciques following next, and the cage bringing up the rear, advanced relentlessly down the lane to the central stage. The gargoyle-faced ape-man who held the stage alone danced with increasing wildness, writhing, twisting, with weird suppleness. Upon the dancing giant the procession bore down, and before him it finally halted.

The halt left the Duca and the king ape facing each other, and the ape ended his dance. After each had given a salute made by raising their arms, both Duca and the king ape turned to face the creatures who were standing with the cage slung across their shoulders. Whereupon the bearers of the cage advanced with it until they stood between two of the tall poles. There, facing the ominous hole in the center of the clearing, with a pole on either side of them, the ape-men lowered the cage to the ground.

Kirby felt his last hope and courage ebbing. Now he noticed that each pole was equipped with a rope which pa.s.sed through a hole near its top, like a thread through the eye of a needle. And while he stared at the dangling ropes, the ape-men made one end of each fast to a ring in the top of the cage. The next instant they leaped back, and began to heave at the other end of the lines.

From the drums came a quicker pounding, a more head-splitting volume of thunder. Over all the ape-people who watched the show, pa.s.sed a shiver of what seemed to be whole-souled, ecstatic satisfaction. Slowly, as the two ape-men heaved hard, the cage swung off the ground, and slowly rose higher and higher into the moonlit air.

When finally the thing hung high above the heads of the mult.i.tude, swaying midway between its tall supports, the ape-men who had done the hoisting fastened their lines to cleats on the poles. Then they turned to the Duca and the giant king who stood behind them, executed a queer, lumbering bow, and fell back to the rear.

The next moment it seemed as though every creature in the clearing--men and those who were only half men--had gone crazy. The king flung himself into the air as if he were a ma.s.s of bounding rubber. Following his lead, the whole a.s.sembly let out howls that drowned even the drums, and then began to sway, to squirm, to leap, even as their king was doing before them.

The caciques and the Duca joined in the madness of foul dancing as heartily as any there. Their eyes were flaming, their long robes flapping, their beards streaming.

On his perch in the tree Kirby muttered an oath which was lost, swept away like a breath, in the shrieking turmoil of sound. Then he turned to Ivana.

"They've brought Naida here to sacrifice her."

"But _why_?" Ivana's sweet face was frozen in lines of horror. "I've been able to guess what was going to happen to her. But--_sacrifice_.

Why will it be that?"
