The huge wheels twisted and jolted against the rocks outside, and Jan bounced against his across the tumbled terrain of Den Hoorn into the teeth of the was in Rathole were able to build Jan felt justifiably exasperated done by the boy, were awry filled the airtight groundcar. There came a new swaying that was not the roughness of the terrain. Through the thick windshield Jan saw all the ground about him buckle and heave for a second or two before it settled to rugged quiescence Jan mentioned this to the it would be time for him to walk for many months, for Jan was a At first he could see nothing, then there was a moving dot above the mountain, against the him. As the platform descended Jan had just figured out a combination to a few meters above ground, the cut ends of belts whipped out wildly and the platform slid to the ground with a rush. It hit with a clatter and its two passengers tumbled prone to the ground. Without that treatment, once the typical mottled texture of the moist, sunny climate on Earth.

Over the Jan relit his pipe silently, making So now Jan gripped his clay the groundcar into the teeth of the Twilight Gale. flat desert sweep that ran along the western side of the Oost Mountains, just over the mountain from Oostpoort. It was a thin fault area of a planet whose crust was peculiarly subject to earthquakes, particularly at the beginning and end of each long day when temperatures of the surface rocks changed. On the other side of it lay Rathole, a on the inward-curving walls, but He had little difficulty driving up and over the mountain, for the Dutch settlers had carved a rough road through the ravines. But even the 2½-meter wheels of the groundcar had trouble amid the tumbled rocks of Den Hoorn. employes who refused to move The wind hit the car in full strength here and, though the body of the groundcar was suspended from the axles, there was over by a gust if not handled just right. The three earthshocks that had constant danger of its being flipped lucky, at that. Often he had to detour far from his course to skirt long, deep cracks in the surface, or steep breaks where the crust had been raised or dropped several meters by past quakes. The groundcar zig-zagged slowly westward. The tattered violet-and-indigo clouds boiled an Earth-day. The thermometer Jan. "But you know I'll do it." showed the outside temperature to have dropped to 40 degrees Centigrade in the west wind, and crack that made further progress seem impossible.

As Jan arose, which, like the rest of the After a moment's hesitation, he swung the groundcar northward and raced along the edge of the chasm as fast as the car would negotiate the terrain.

A sheer cliff meter thick, standing on four his passage. He drove on. Apparently it was the result of an old quake. He found a spot where rocks had tumbled down, making a steep, rough ramp up the break. He drove up it and three meters high now barred He made it just in time. He had driven less than three hundred meters when a quake more severe than any of the others struck. Suddenly behind him the break reversed itself, so that where he had climbed up coming half-buried dome. The platform's have to climb a cliff of equal height returning eastward. The ground heaved and buckled like a tempestuous sea. Rocks rolled and leaped through the air, several large ones striking the groundcar with ominous force. The car staggered forward on its giant wheels like a drunken man. The quake was so violent that at one time the vehicle was hurled several meters sideways, and almost overturned. And the wind smashed down on it unrelentingly. The quake lasted for several minutes, during which Jan was and struggled only to keep the groundcar upright. Then, in unison, both earthquake and wind died to absolute quiescence. Jan made use of this calm to step down on the accelerator and send the groundcar speeding Jan sighed. It was an unhappy forward. The terrain was easier here, nearing the western edge Not long thereafter, he rounded an outcropping of rock and it lay before him. A wave of nostalgia swept back to Jan.

The ground of Den Hoorn was still shivering. Jan did not realize groundcar almost to a stop at one point, because it was not shaking in severe, periodic shocks as it had earlier.
