"And the riddle of the city about me seemed unsolvable also. What could I find in this half-buried mass of stone fragments to throw light on the past? I could not even superficially explore the place, for the scantiness of my supplies and water would not permit; a long stay. It was with a discouraged heart that I went back to the; camels and, leading them to an open spot in the ruins, made my camp for the night. And when night had fallen, and I sat beside my little fire, the vast, brooding silence of this place of death was awful. There were no laughing human voices, or cries of animals, or even cries of birds or insects. There was nothing but the darkness and silence that crowded around me, flowed down upon me, beat sullenly against the glowing spears of light my little fire threw out.
"As I sat there musing, I was startled by a slight sound behind me. I turned to see its cause, and then stiffened. As I have mentioned, the space directly around my camp was clear sand, smoothed level by the winds. Well, as I stared at that flat expanse of sand, a hole several inches across suddenly appeared in its surface, yards from where I stood, but clearly visible in the firelight.
"There was nothing whatever to be seen there, not even a shadow, but there it was, one moment the level surface of the sand, the next moment a hole appearing in it, accompanied by a soft, crunching sound. As I stood gazing at it in wonder, that sound was repeated and simultaneously another hole appeared in the sand's surface, five or six feet nearer to me than the other.
"When I saw that, ice-tipped arrows of fear seemed to shoot through me, and then, yielding to a mad impulse, I snatched a blazing piece of fuel from the fire and buried it, a comet of red flame, at the place where the holes had appeared. There was a slight sound of scurrying and shuffling, and I felt that whatever thing had made those marks had retreated, if a living thing had made them at all. What it had been, I could not imagine, for there had been absolutely nothing in sight, one track and then another appearing magically in the clear sand, if indeed they were really tracks at all.
"The mystery of the thing haunted me. Even in sleep I found no rest, for evil dreams seemed to flow into my brain from the dead city around me. All the dusty sins of ages past, in the forgotten place, seemed to be focused on me in the dreams I had. Strange shapes walked through them, unearthly as the spawn of a distant star, half icon and vanishing again.
"It was little enough sleep I got that night, but when the sun finally came, with its first golden rays, my fears and oppressions dropped from me like a cloak. No wonder the early peoples were sun-worshippers!
"And with my renewed strength and courage, a new thought struck me. In the inscription I have quoted to you, that long-dead merchant-adventurer had mentioned the great temple of the city and dwelt on its grandeur. Where, then, were its ruins? I wondered. I decided that what time I had would be better spent in investigating the ruins of this temple, which should be prominent, if that ancient Carthaginian had been correct as to its size.
"I ascended a near-by hillock and looked about me in all directions, and though I could not perceive any vast pile of ruins that might have been the temple's, I did see for the first time, far away, two great figures of stone that stood out black against the rosy flame of the sunrise. It was a discovery that filled me with excitement, and I broke camp at once, starting in the direction of those two shapes.
"They were on the very edge of the farther side of the city, and it was noon before I finally stood before them. And now I saw clearly their nature: two great, sitting figures, carved of black stone, all of fifty feet in height, and almost that far apart, facing both toward the city and toward me. They were of human shape and dressed in a queer, scaled armor, but the faces I can not describe, for they were unhuman. The features were human, well-proportioned, even, but tile face, the expression, suggested no kinship whatever with humanity as we know it. Were they carved from life? I wondered. If so, it must have been a strange sort of people who had lived in this city and set up these two statues.
"And now I tore my gaze away from them, and looked around. On each side of those shapes, the remains of what must once have been a mighty wall branched out, a long pile of crumbling ruins. But there had been no wall between the statues, that being evidently the gateway through the barrier. I wondered why the two guardians of tile gate had survived, apparently entirely unharmed, while the wall and the city behind me had fallen into ruins. They were of a different material, I could see; but what was that material?
