That somewhere seemed likely to be the great central community which Ivana said was rumored to exist in the far reaches of the Rorroh. The problem was how to locate the community through the hideous country. But Kirby presently drove the question from his head. To-morrow's evils could best be faced when morrow dawned.

Enough light had grown now so that the swirling bosom of the river, and a strip of sand directly below the cliff in which their cave was set, were visible. As Kirby let his eyes wander to the lush growth beyond the sand, he heard something which made him stir uneasily. Some creature which suggested power and hugeness immeasurable was moving there.

The brush parted, and he saw plainly an animal with the bulk of a two-story house. On two feet the nightmare thing stood, as lightly as a cat, and then came down on all four feet as it ambled out on the sand and extended into the lapping river a tremendous beak studded with teeth. A smell of crushed weeds and the musty odor like that of a lion house filled the night. The tyranosaur--it was more like a tyranosaur than anything else--breathed heavily and guzzled in great mouthfuls of water.

Kirby sat perfectly still. He hoped the thing would go away. But the tyranosaur did not go away. All at once it hissed loudly and stood up, its eyes glowing green and baleful, and Kirby leaned forward.

From the water was slithering another creature with a gigantic, quivering, jelly body. Kirby saw to his horror that, in addition to four short legs with webbed, claw-tipped feet, there sprouted from the body a number of octopus tentacles. From the scabrous mottle of the head, cruel, unintelligent, b.e.s.t.i.a.l eyes glared at the rearing tyranosaur.

One of the serpentine tentacles whipped out, slapped against the tyranosaur's fore-shoulder to call forth a hiss and a short bellow. Then other tentacles waved in the moonlight, and in a flash the tyranosaur was enmeshed as by a score of slimy cables. He was not altogether helpless. Suddenly the steam shovel of a beak buried itself in the jelly body of the water animal, and there spurted out a flood of inky liquid.

The water animal emitted a sickening gurgle. But the tyranosaur's advantage was only temporary. Closer and closer drew the ugly, scabrous tentacles. The tyranosaur never had a chance. Its green eyes flared, the shovel beak plunged and slashed, but never for a second did the tentacles relax. As Kirby stared, he saw the water animal begin to back up, dragging its gigantic enemy with it. For a second the whole night was hideous with the sound of hisses, gurgles, dashing water. Then the river boiled once and for all, and both animals sank in its depths.

Kirby chafed cold hands together and shivered a little, then turned to see if Nini and Ivana had heard the struggle.

Fortunately, however, they still slept. And as if this peace which was upon them were an omen of good, the jungle continued quiet for the next hour. Kirby wakened them at last, and after a s.n.a.t.c.hed nap, was in turn awakened.

The three of them started again when the first glimmerings of dawn came to the forest. Of food there was plenty--fruits which grew in profusion, and some roots which Nini grubbed out of the earth. Having started along the first trail which they encountered beside the river bank, they ate as they walked.

Kirby judged they had kept their steady gait for more than two hours before a slight widening of the trail roused him from the preoccupation into which he had fallen.

"See there," he exclaimed to both girls, and pointed at a grove of trees with fanlike leaves which towered up to the right of the trail. "What are those big bundles fastened to the lower limbs?"

Ivana glanced at Nini, who nodded as if in answer to a question.

"This must be one of the places where the ape-people leave their dead,"

Nini answered. "The bundles--But come over to them."

Kirby forced his way ahead until he stood beneath a huge, unsavory bundle wrapped in roughly woven brown fibre, and wedged in a fork between two limbs. Judging from the ugly odor which overhung the grove, there could be no question about what the bundle contained. Nini and Ivana, glancing at the scores of similar bundles which burdened the trees of the whole grove, made wry faces. Kirby slung his rifle in the crook of his arm, and nodded toward the trail.

"There must be a village somewhere near," he said.

A mile farther on they found what they were seeking, a colony of seventy or eighty conical dwellings of mud and thatch, which were ranged in a double circle about a central common of bare, well-trodden earth. It took no long reconnaissance to discover that the town was deserted completely of all inhabitants.

Ivana beckoned and darted to one of the nearest huts, and Kirby, following her, found lying on the uneven earth floor within, a half-skinned animal which resembled a small antelope. An obsidion knife beside the carca.s.s, the disordered condition of a couch of gra.s.s, the sour odor of recent animal occupancy, all told their story.

"The owner left in a hurry," Kirby observed aloud.

Nini, who had gone beyond, to a larger hut which might have belonged to a king ape, called out excitedly to them.

"A great number of apes have eaten a hurried meal here!"

Kirby entered the shadowed, foul-smelling interior of the central hut to find her statement true. Broken meats, some raw, some cooked, lay on the dirt floor, and scattered bits of fruit were mingled with them. The ashes of a burned out fire at the hut entrance were cold, but had not been for long.

"Do you think--" Ivana began.

"I think the whole of the Duca's horde came this way, fed, and went on, taking everyone with them," Kirby finished.

"But which direction did they take?" asked Nini, who was standing at the door of the big hut and had already begun to examine the crowding, green, inscrutable walls of jungle which foamed up to the clearing on all sides.

No less than seven trails wound away into the dark country beyond, and Kirby saw that the question would not be an easy one.

Having hastily circled the clearing and peered down one trail after another without finding a clue, he knew that it was the Duca's intelligence which had made the ape-people depart without leaving even tracks behind them. He did not like the situation.

"Well," he rumbled to his companions, "we may as well take our choice.

One chance in seven of coming out right!"

But the words were hardly out of his mouth before he pulled himself up with a jerk, and cursed himself for having given in.

"Ivana! Nini!" Sharpness, a sudden ring of hope edged his voice. "Am I seeing things, or is that--"

As he pointed to a huge aloe bush down one of the trails to their left, they started to run. Then Kirby knew that he was not seeing things. What his first inspection of the trails had failed to show, he saw plainly now.

Tied loosely to one branch of the aloe bush, almost concealed amidst the deep green of foliage, was a bit of white cloth! In a second Kirby was holding out to his companions a tiny strip of Naida's wedding gown.

"She knew we would come!" He stared down the trail with narrowed, keen eyes.

How Naida had contrived to leave her signal was more than they knew. The fact that she _had_ done so, sent all three of them down the trail at driving speed.

An hour pa.s.sed, then another, and the morning which had been barely born when they first took the trail, wore on to the sultriness and vast, colored light of a tropical noon. Twice the main trail forked, and twice they found an un.o.btrusive bit of cloth to guide them beyond the works.

When the hands of Kirby's still useful watch pointed to twelve, they paused to eat and rest. Then they pushed on.

Meanwhile, the country through which they pa.s.sed left Kirby with a clear understanding of why Naida and her people had shunned the Rorroh forest down the centuries of time.

Just one thing which stuck in his head was the sight of a small creature like a marmoset, sticking an inquisitive nose into the heart of a sickly-sweet plant which resembled a terrestrial nepenthe. No sooner had the little pink snout touched the green and maroon splotched petals, than the plant writhed, closed its leaves, and swallowed the monkey whole. Little squeaks of agony and terror sounded for a moment, and ceased.

At midafternoon they paused in a spot where a forest of trees with whorled tops were slowly being strangled to death by immense orchids of every conceivable shape and color, and by a kind of creeping mistletoe which grew almost as they watched. Here also, the ground was covered with fluffy, grey-green moss which seethed constantly as if it were a carpet of maggots. Both Ivana and Nini warned Kirby on his life not to touch or go near the moss, and a moment later he knew why.

From the forest came the flash of a small, five-toed horse being pursued by some animal with a hyena head that barked. At the edge of the mossy glade the hyena swerved aside, but the terrified horse plunged straight out on the carpet of moss. Instantly the air was filled with the sound of animal screams, and a series of tiny, m.u.f.fled explosions. A cloud of greenish-red mist swirled about the horse. Quivering, still screaming, the animal went down on its knees, and as the reddish green smoke fell on him and settled, it became a ma.s.s of growing moss spores.

Before Kirby's eyes, the pitiful animal was covered by a shroud of green that spread over him and cloaked him, licking over all with tiny sounds like far off m.u.f.fled drums as fresh spore cases developed and burst. The screams died. Even as Kirby drew the girls to him and they pa.s.sed on, the horse's nostrils, eyes, mouth were filled with choking green moss; and he lay still.

On and on, deeper into the jungle Kirby pushed, and never for a moment did his companions falter. But the way was not so easy now, for nerves were jaded, muscles sore, and no human will could have been powerful enough to cast aside the growing fear for Naida.

Fear came finally to a head when, toward dusk, Kirby sighted a fork ahead of them, approached it confidently to look for Naida's sign, and found nothing.
