and once only, and never thought to find any necessity in life strong enough to drive her down again. The way was the strangest she had ever known. There was, she thought, no such passage in all the world save here. It had not been built for human feet to travel. It had not been built for feet at all. It was a narrow, polished shaft that cork- screwed round and round. A snake might have slipped in it and gone shooting down, round and round in dizzy circles—but no snake on earth was big enough to fill that shaft. No human travelers had worn the sides of the spiral so smooth, and she did not care to speculate on what creatures had polished it so, through what ages of passage.
    She might never have made that first trip down, nor anyone after her, had not some unknown human hacked the notches which made it possible to descend slowly; that is, she thought it must have been a human. At any rate, the notches were roughly shaped for hands and feet, and spaced not too far apart; but who and when and how she could not even guess. As to the beings who made the shaft, in long- forgotten ages—well, there were devils on earth before man, and the world was very old.
    She turned on her face and slid feet-first into the curving tunnel. That first time she and Gervase had gone down in sweating terror of what lay below, and with devils tugging at their heels. Now she slid easily, not bothering to find toeholds, but slipping swiftly round and round the long spirals with only her hands to break the speed when she went too fast. Round and round she went, round and round.
    It was a long way down. Before she had gone very far the curious dizziness she had known before came over her again, a dizziness not entirely induced by the spirals she whirled around, but a deeper, atomic unsteadiness as if not only she but also the substances around her were shifting. There was something queer about the angles of those curves. She was no scholar in geometry or aught else, but she felt intuitively that the bend and slant of the way she went were somehow outside any other angles or bends she had ever known. They led into the unknown and the dark, but it seemed to her obscurely that they led into deeper darkness and mystery than the merely physical, as if, though she could not put it clearly even into thoughts, the peculiar and exact lines of the tunnel had been carefully angled to lead through poly-dimensional space as well as through the underground—perhaps through time, too. She did not know she was thinking such things; but all about her was a blurred dizziness as she shot down and round, and she knew that the way she went took her on a stranger journey than any other way she had ever traveled.
    Down, and down. She was sliding fast, but she knew how long it would be. On that first trip they had taken alarm as the passage spiraled so endlessly and with thoughts of the long climb back had tried to stop before it was too late. They had found it impossible. Once embarked, there was no halting. She had tried, and such waves of sick blurring had come over her that she came near to unconsciousness. It was as if she had tried to halt some inexorable process of nature, half finished. They could only go on. The very atoms of their bodies shrieked in rebellion against a reversal of the change.
    And the way up, when they returned, had not been difficult. They had had visions of a back-breaking climb up interminable curves, but again the uncanny difference of those angles from those they knew was manifested. In a queer way they seemed to defy gravity, or perhaps led through some way outside the power of it. They had been sick and dizzy on the return, as on the way down, but through the clouds of that confusion it had seemed to them that they slipped as easily up the shaft as they had gone down; or perhaps that, once in the tunnel, there was neither up nor down.
    The passage leveled gradually. This was the worst part for a human to travel, though it must have eased the
