That night I surrounded myself with a ring of fire which I fed with dry grass and stalked plants which burned slowly and I felt comparatively safe, though huge forms moved about me in the darkness, and I caught the stealthy pad of great paws, and the glimmer of wicked eyes.

On my journey across the plains I subsisted on fruit I found growing on green stalks, which I saw the birds eating. It was pleasant to the taste, though lacking in the nutritive qualities of the nuts in the hills. I looked longingly at the scampering deerlike animals, now that I had the means of cooking their flesh, but saw no way of securing them.

And so for days I wandered aimlessly across those vast plains, until I came in sight of a massive walled city.

I sighted it just at nightfall, and eager though I was to investigate it further, I made my camp and waited for morning. I wondered if my fire would be seen by the inhabitants, and if they would send out a party to discover my nature and purpose.

With the fall of night I could no longer make it out, but the last waning light had shown it plainly, rising stark and somber against the eastern sky. At that distance no evidence of life was visible, but I had a dim impression of huge walls and massive towers, all of a greenish tint.

I lay within my circle of fire, while great sinuous bodies rustled through the grass and fierce eyes glared at me, and my imagination was at work as I strove to visualize the possible inhabitants of that mysterious city. Would they be of the same race as the hairy ferocious troglodytes I had encountered? I doubted it, for it hardly seemed possible that these primitive creatures would be capable of rearing such a structure. Perhaps there I would find a highly developed type of cultured man. Perhaps-here imaginings too dark and shadowy for description whispered at the back of my consciousness.

Then the moon rose behind the city, etching its massive outlines in the weird golden glow. It looked black and somber in the moonlight; there was something distinctly brutish and forbidding about its contours. As I sank into slumber I reflected that if apemen could build a city, it would surely resemble that colossus in the moon.
