ings grew lower. Warehouses gave way to factories, factories to apartment buildings, apartment buildings to dwellings which were at first small and dirty white, then large and mansion-like but very much decayed, then new and monotonous in their uniformity. Peoples of different economic status and racial affiliations filed into and emptied from the street car as the different strata of the city were passed through. Finally the vacant lots began to come, at first one by one, then in increasing numbers, until the houses were spaced out two or three to a block.
"End of the line,” sang out the conductor, and without hesitation David swung down from the platform and walked on in the same direction that the street car had been going. He did not hurry. He did not lag. He moved as an automaton that had been wound up and set going, and will not stop until it runs down.
The sun was setting smokily red in the west. He could not see it because of a tree-fringed rise ahead, but its last rays winked at him from the window panes of little houses blocks off to right and left, as if flaming lights had been lit inside. As he moved they flashed on and off like signals. Two blocks further on the sidewalk ended, and he walked down the center of a muddy lane. After passing a final house, the lane also came to an end, giving way to a narrow dirt path between high weeds. The path led up the rise and through the fringe of trees. Emerging on the other side, he slowed his pace and finally stopped, so bewilderingly fantastic was the scene spread out before him. The sun had set, but high cloud-banks reflected its light, giving a spectral glow to the landscape.
Immediately before him stretched the equivalent of two or three empty blocks, but beyond that began a strange realm that seemed to have been plucked from another climate and another geological system and set down here outside the city. There were strange trees and shrubs, but, most striking of all, great uneven blocks of reddish stone which rose from the earth at unequal intervals and culminated in a massive central eminence fifty or sixty feet high.
And as he gazed, the light drained from the landscape, as if a cloak had been flipped over the earth, and in the sudden twilight there rose from somewhere in the region ahead a faint howling, mournful and sinister, but in no way allied to the other howling that had haunted him day and night. Once again he moved forward, but now he moved impulsively toward the source of the new sound.
A small gate in a high wire fence pushed open, giving him access to the realm of rocks. He found himself following a gravel path between thick shrubs and trees. At first it seemed quite dark, in contrast to the open land behind him. And with every step he took, the hollow howling grew closer. He felt as though he were walking through a dream world. Finally the path turned abruptly around a shoulder of rock, and he found himself at the sound’s source.
A ditch of rough stone about eight feet wide and of a similar depth separated him from a space overgrown with short, brownish vegetation and closely surrounded on the other three sides by precipitous rocky walls in which the dark mouths of two or three caves showed. In the center of the open space were gathered a half dozen white-furred canine figures, their muzzles pointing toward the sky, giving voice to the mournful cry that had drawn him here.
It was only when he felt the low iron fence against his knees and made out the neat little sign reading, artic wolves, that he realized where he must be—in the
