"Say!" Tommy jumped to his feet in sudden remembrance. "I saw a bush, back there about fifty feet, with bunches of big red berries on it.

Like grapes, they looked. May be good to eat."

"Sure, they _may_ be. And then again they may be poison. We can't take any chances like that. Leave 'em alone."

Tommy growled unintelligibly and fell to walking around their shelter with nervous strides, keeping just within the dry area and glaring savagely into the steaming jungle. Blaine smiled grimly. Nerves! Tommy always was like that; always had to be on the go and doing something.

His own nerves were jumpy to-day. They were in hot water this time, for sure. Had to keep on though; they were still alive, or at least half alive; and the solar system was intact as yet. If only Tom Farley would quit his infernal tramping!

"Cut it out!" Blaine snapped peevishly. "You'll have us both bughouse.

Can't you sit down and take it easy?"

Tommy stopped in his tracks. "Sorry, Blaine," he said. But he remained standing, staring off into the jungle. Then, suddenly he exclaimed, "Say, I'm going for some of those grapes, or whatever they are. I'll bring a mess of them back and we can wait till Ulana wakes up. She'll know whether they're poison or not."

"Oh, go ahead. But don't get yourself lost. Yell out if you can't find us and I'll answer."

"Okay. Don't worry about me." And in three steps Tommy was swallowed up in the undergrowth.

Blaine stole a glance at the girl and something caught at his throat.

G.o.d, she was beautiful! There must be some way of getting her out of this mess. Dantor, perhaps, might show the way. He ought to be sending that message soon--a mental one, Tiedus said. Poor kid, Tiedus; gone to the happy hunting grounds now, no question of that. And he intended to advise Dantor from the spirit world. As simple as that, it was. They were game, these Rulans. Fatalists, though, and resigned to the inevitable; hopeless. But a wonderful people in a rotten world.

Soon he felt his head droop and in a moment he began to doze.

When he awoke it was to the touch of Ulana's soft fingers on his arm.

"We are alone?" she asked.

"Lord!" he exclaimed, rising stiffly and rubbing the sleep from his eyes. "How long have I napped? I shouldn't have."

A swift look around the small clearing disclosed the fact that Tommy was missing. He shouldn't have let him go. A sudden panic gripped him.

"Tommy! Tommy!" he called out.

There was not even an echo in reply. Only the whispering of the jungle overhead and all around them. His friend was gone.

"Ulana," he said, his voice trembling, "we _are_ alone. Farley is lost; swallowed up in this terrible forest."

And then, suddenly, she was in his arms. Those wondrous blue eyes, swimming in tears, looked into his own. Soft red lips, upturned, met his lips; clung there.

"I am sorry, my Carson," she said softly, when he had released her: "sorry that your good friend is lost. But perhaps," more brightly--"he has but strayed away. When the mental message comes you will be reunited. He will hear it as well as you."

Blaine shook his head. In his own heart he knew he would never see Tommy again. He had wandered too close to the Tritu Anu and had been overpowered by the green-bronze guards. Their ray pistols--he shuddered at the thought.

"I have _you_ now, my Carson," the girl was saying. "Only you."

In a daze of pain and happiness intermingled, he knew he was holding her close, drawing her fiercely to him. And then, raising dull eyes to stare over the precious head and into the jungle that hid his friend, he froze with horror.

A flat serpent head with wide slavering mouth and beady eyes swayed there directly behind her. Pendant, it was, on a scaly and slimy length of undulating body that coiled high above in the matted growths of the jungle. As he watched, rooted to the spot, the great head drew back and poised, vibrating, ready to strike.

In one quick movement he flung the girl aside and whipped out the ray pistol he had taken from Pegrani. He pressed the release and a whirring sound came from the little weapon. But no crackling blue flame sprang forth to blast this creature into nothingness. Jumping aside, he was thrown to the ground by its lashing body as the great snake struck and missed.

But the pistol was useless. Short circuited by moisture, no doubt. He crouched there, calling huskily to Ulana. She must run for it; force her way into the thick undergrowth where the thing could not reach her.

She lay there, helpless with terror. Then, in a flash, she was on her feet dashing to his side. G.o.d, the huge head was poised there again!

Pulsating! The glittering avid eyes upon them!

Instinctively Blaine raised the pistol just as the head darted downward. The release clicked home. And, wonder of wonders, the blue flame crackled spitefully. Exploding atoms, dazzling in the green twilight. Mighty thrashings of the huge coils high up in the tangled foliage. Crashing and tearing of great stems and rope-like tendrils.

But the enormous body was headless; a dead thing in the throes of its final reflexes. Only the one charge had been spoiled; the little pistol had served them well.

He drew Ulana into the thickest of the undergrowth for protection against the tremendous lashing thing that crashed into the small clearing where the giant mushroom grew. Their shelter was destroyed. He must find another; he must be forever on guard over this girl whose hand clung so confidently to his own as they wedged their way into the thicket.

"Carson! Ulana!" A familiar voice rose above the whisperings of the jungle. A voice familiar, yet unreal; supernatural; a calm, commanding one that did not sound but echoed only in the consciousness.

"Hark!" Ulana gripped his hand more tightly. "Did you hear? It is Dantor. The message Tiedus promised."

In awed silence they waited. A tiny ball of orange fire flamed suddenly in the depths of the rushes directly before them. A sign!

"Ah, you are there!" the voice broke in. "I have your mental reactions.

You will follow the orange beacon to the Tritu Anu where I await your coming. Be of good cheer, my children."

What magic was this? The science of the Rulans was beyond the comprehension of the Earth man. Here was telepathy in its most perfect form. Communications from the spirit plane; the orange flame--it was all so utterly fantastic that Blaine had to look earnestly at the girl to a.s.sure himself it was not a dream. She smiled confidently.

And the orange flame was moving off into the undergrowth. They must follow its beckoning, flickering light.

It was a nightmare, that journey back through the jungle to the Tritu Anu. Dantor must be in a fearful hurry, for the orange flame moved swiftly. If they stopped a moment to rest it danced there impatiently, then receded into the green shadows until they were forced to follow for fear of losing it. Ulana's light robe was torn and sodden with moisture. The perfectly rounded ivory shoulders, bare now, were scratched and bleeding from contact with th.o.r.n.y protuberances that covered some of the lighter reed-like stems.

But the brave girl was uncomplaining. She clung doggedly to the Earth man's hand when they were able to walk erect: followed swiftly and unquestioningly when they were compelled to crawl or wriggle through an almost impenetrable thicket.

Once she cried out in alarm and Blaine turned back to see that the wiry tendrils of a spiny, globular plant had wound themselves around her slim body and held her fast. As he grasped her hand to draw her away, others of the tendrils curled about his wrist and he too was imprisoned. They burned the flesh, those writhing things, and tugged mightily. Ulana screamed with the pain of the many that held her in their tightening grasp.

It was alive, this thing that grew there, a huge ball with a thousand stinging tentacles. A carnivorous plant. Even as the realization flashed across his mind he saw that the spiny sphere was opening. Split vertically, the two halves fell apart to disclose the steaming interior whose walls were lined with sharp dagger-like projections a foot in length. And the wiry tendrils were drawing them in!

Almost insane with horror, Blaine released the disintegrating energy of the weapon he still carried in his free hand. Twice he pressed its release and twice the searing blue flame spurted from the gla.s.s tube that was its muzzle. Only a few charges remained now in the marvelous weapon but once more it had served then well. The open-mouthed plant monster vanished with the clearing of the blue vapor and the ensnaring tendrils relaxed, falling from their bodies like so many loosened cords. Blaine caught the swooning girl in his arms.

Half carrying her, he struggled on after the orange flare. The base of one of the latticed supporting columns loomed vast in the eery twilight gloom, and he leaned a moment against one of its vine-wrapped members.

The girl was exhausted and hung limp in his circling right arm. Still the orange beacon danced on. If only Dantor would ease up a bit.

Couldn't he give them a little time?

On and on he staggered, ploughing through the sloppy footing and the dripping clinging greens that were everywhere in his path. Slimy fronds wrapped themselves around them, impeding his progress; clinging as if they too were alive. The whispering silence closed in on them, vast and mysterious. Menacing; awful....
