I picked up the twilight zone without difficulty in the television disc, and at full power examined the terrain. The rich crops that fairly burst from the earth of the sunlit portion of Antri were not to be observed here. The Antrians made no effort to till this ground, and I doubt that it would have been profitable to do so, even had they wished to come so close to the darkness they hated. The ground seemed dank, and great dark slugs moved heavily upon its greasy surface. Here and there strange pale growths grew in patches--twisted, spotted growths that seemed somehow unhealthy and poisonous. I searched the country ahead, pressing further and further into the line of darkness that was swiftly approaching. As the light of the sun faded, our monstrous searchlights cut into the gloom ahead, their great beams slashing the shadows. In the dark country I had expected to find little if any vegetable growth. Instead, I found that it was a veritable jungle through which even our searchlight rays could not pass. How tall the growths of this jungle might be, I could not tell, yet I had the feeling that they were tall indeed. They were not trees, these pale, weedy arms that reached towards the dark sky. They were soft and pulpy, and without leaves; just long naked sickly arms that divided and subdivided and ended in little smooth stumps like amputated limbs. That there was some kind of activity within the shelter of this weird jungle, was evident enough, for I could catch glimpses, now and then of moving things. But what they might be, even the searching eye of the television disc could not determine. * * * * * One of our searchlight beams, waving through the darkness like the curious antenna of some monstrous insect, came to rest upon a spot far ahead. I followed the beam with the disc, and bent closer, to make sure my eyes did not deceive me. I was looking at a vast cleared place in the pulpy jungle--a cleared space in the center of which there was a city. A city built of black, sweating stone, each house exactly like every other house: tall, thin slices of stone, without windows, chimneys or ornamentation of any kind. The only break in the walls was the slit-like door of each house. Instead of being arranged along streets crossing each other at right angles, these houses were built in concentric circles broken only by four narrow streets then ran from the open space in the center of the city to the four points of the compass. Around the entire city was an exceedingly high wall built of and buttressed with the black, sweating stone of which the houses were constructed.
