caught in it.
Rohan thought that he could make out cube-like and pyramid-shaped remnants of rocks supporting a dried-out, dead vegetation. Even this impression dwindled the closer he came: despite the chaotic destruction a certain regular pattern was still evident that was alien to any organic lifeforms. These were no genuine massive ruins. It was possible to peer inside through the many chinks in the metal thicket. And yet they were not hollow, for they were entirely filled by this impenetrable growth. Above everything hung the breath of deadly loneliness and isolation.
Rohan thought of the antimatter mortar, but even the use of force would produce no real results, for here was nothing to be invaded. The storm swept stinging clouds of dust through the tall bastions. The even mosaic of the black apertures was filled with sand that trickled down in a steady stream to build up steep cones at the foot of the honeycombs. This dry sound of the trickling sand never left them during the foray into the ruins. But there was nothing but utter silence from the whirling antennae, the Geiger counters, the supersonic microphones and the radiation dosimeters. The crunching of sand under wheels and the howling of the starting motors were the only noise to be heard as the colonnade changed direction. The troop now swerved off to one side and soon disappeared in the deep cool shade of the gigantic constructions, After a while they came out again into the bright light that lay scarlet red on the sand.
Finally they arrived at the tectonic fissure. It was a crevice one hundred yards wide, its depth unfathomable: it had not yet been filled in by the sand that was constantly swept down from the edges by violent gusts of wind.
They stopped, and Rohan sent the flying scouter robot across the chasm. He followed the robot’s progress on his television screen, observing whatever the tele-lenses were registering. But there was always the same familiar sight. Rohan recalled the scouter one hour later. As soon as it had returned to the troop, he had a brief consultation with Ballmin and the physicist Gralew who were traveling with him in his vehicle. They decided to take a closer look at some of the ruins.
At first they tried to measure the depth of the sand layer which covered the “streets” of the dead “city.” They used supersonic probes: a rather wearisome procedure, as it turned out, for the various test results conflicted with each other. Probably this was due to some decrystallization process that had occurred inside the rocky ground as it was torn apart by an earthquake. This was a possible explanation for the origin of the chasm. The depth of the sandy stratum covering the gigantic basin within this sector seemed to vary from seven to twelve yards.
They changed direction again, now turning to the east, toward the seashore. After following a zigzag course for about seven miles through the black ruins that became gradually lower and then finally completely disappeared in the sand, the expedition reached bare rocky ground. They came to a halt on top of a cliff that was so high above the sea that they could hear the breakers only as a weak murmur far below. The coast line was a barren chain of rocks that looked unnaturally smooth, almost polished. Toward the north the shore rose to form a line of mountain peaks that plunged abruptly into the ocean like a petrified waterfall.
They had left the “city” behind them. Now its silhouette stood out black against the reddish horizon. Rohan called the Invincible to report what few findings they had managed to get. Then the group turned around, driving back to the interior of the field of ruins. The men were careful to observe all precautionary measures, driving under the shelter of their energy screen.
On the way back one of the energo-robots enlarged the area of its force field—probably because of some tiny directional error—and its edge brushed against the overhang of a pointed
