the butt of his blaster. Silly weapon, stupid popgun—what could he do? Decision came. With a curse, he whirled and ran back into the pyramid. His flash lit the endless downward passages with a dim bobbing radiance, and the shadows swept above and behind and marched beside, the shadows of a million years closing in to smother him. His boots slammed against the stone floor, thud-thud-thud—the echoes caught the rhythm and rolled it boomingly ahead of him. A primitive terror rose to drown his dismay; he was going down into the grave of a thousand millennia, the grave of the gods, and it took all the nerve he had to keep running and never look back. He didn't dare look back. Down and down and down, past this winding tunnel, along this ramp, through this passageway into the guts of the planet. A man could get lost here. A man could wander in the cold and the dark and the echoes till he died. It had taken him weeks to find his way into the great vault, and only the clues given by Murchison's reports had made it possible at all. Now— He burst into a narrow antechamber. The door he had blasted open leaned drunkenly against a well of night. It was fifty feet high, that door. He fled past it like an ant and came into the pyramid storehouse.

He had energized some of the units, and they had hummed and flickered, but he had not dared experiment. His idea had been to rig an antigrav unit which would enable him to haul the entire mass of it up to his boat. Once he was home, the scientists could take over. But now— He skinned his teeth in a wolfish grin and switched on the big lamp he had installed. White light flooded the tomb, shining darkly back from the monstrous bulks of things he could not use, the wisdom and techniques of a race which had spanned the stars and moved planets and endured for fifty million years. Maybe he could puzzle out the use of something before the enemy came. Maybe he could wipe them out in one demoniac sweep—just like a stereofilm hero, jeered his mind—or maybe he could simply destroy it all, keep it from Janyard hands. He should have provided against this. He should have rigged a bomb, to blow the whole pyramid to hell— With an effort, he stopped the frantic racing of his mind and
