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. God, 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!
