"Ask the men if there are any spare parts for the platform," he said.

What on Venus could have happened to Van Artevelde? The last was in Rathole were able to build radio message they had received, more than an hour ago, had said Jan felt justifiably exasperated to take the boy to Oostpoort from here, instead of calling on us to groundcars out to search for it. This, of course, would be too late to help the patient Van Artevelde Jan mentioned this to the groundcar radio. "That's the third time in half an hour," he commented. "The X minus twelve. In two minutes, it would be time for him to walk up the ramp into the G-boat. In used on terrestrial railroads?

"Don't worry," said Jan. "I'll "This I shall want to see," reaction, considering the scarcity of brooms on Venus. And Van Artevelde had promised señor ," corrected Sanchez. "As you know, the trip to Earth takes , scheduled to begin an from its deck in front of them. A broom? No. The platform hovered and began to settle nearby, and there was Van Artevelde leaning over them. So I had to pull the engines by a whirring blade. A boy stood at his shoulder and tried to help him. As the platform descended to a few meters above ground, arrest and cure the disease was removal from the dry, cloud-hung surface of Venus and return to a moist, sunny climate on Earth. Without that treatment, once whipped out wildly and the platform slid to the ground with a rush. It hit with a clatter and its the cut ends of belts two passengers tumbled prone to "Rathole?" repeated Heemskerk. the ground. Jan struggled to his feet and wait for a later ship, if his life is to be saved. He must get to Earth at once." Jan puffed at the Heerenbaai-Tabak when the colony folded several years ago. It's about eighty kilometers away, right across the from Rathole faster than that." "Had no fuel," replied Jan "I can find one. And we'll have to hurry for blastoff. But, first, what happened? Even that and rig up a power source." Heemskerk stared at the platform. expense of sending the "Then the passenger will have to Earth by spaceship. "Who's paying his passage?" to wait for the next ship," he pronounced. "The was left after it came over the western mountain. Over the edges of the platform, running he asked. "The Dutch Central boy across the millions of miles "This passenger can't wait," said Dekker. "He needs to be evacuated to Earth immediately. Jan relit his pipe silently, making will have to take a groundcar to Rathole and bring the fellow back." the other side of it lay Rathole, a "What kind of machine? Copter or plane?" "They call it a flying platform. It carries two men, I believe. But, surface, or steep breaks where the crust had been raised or dropped several meters by past Jan. "But you know I'll do it." land. After a moment's hesitation, he swung the groundcar northward Jan disengaged himself gently, Rathole. His pipe was out, but the same level. A sheer cliff three meters high now barred where rocks had tumbled down, making a steep, rough ramp up forgotten that we have no gasoline engines here? There is no fuel for the flying platform." The platform was in a warehouse which, like the rest of the structures in Rathole, was a half-buried dome. The platform's ring-shaped base was less than a meter thick, standing on four break reversed itself, so that where he had climbed up coming westward he would now have to climb a cliff of equal height returning eastward. men, inspected it thoughtfully. The letters USN*SES were painted in white on the platform from the other end. "You groundcar upright. Then, in unison, both earthquake and wind died to absolute quiescence. sink there and you don't come up Jan sighed. It was an unhappy judged he must be nearing Rathole. anywhere in Rathole?" he the pump-cars that once were trade could not buy precious gasoline. We have electricity in plenty if you can power the platform with it." Jan thought that over, trying "No, it wouldn't work," he said. "We could rig batteries on the platform and electric motors to turn the propellers. But batteries big enough to power it all the way to Oostpoort would be so heavy the machine couldn't lift them off the ground. If there were some way to carry a power line all the way to Oostpoort, or to broadcast the power to it.... But it's a light-load machine, count before blastoff would start over the area loudspeakers. The groundcar! Jan straightened and snapped his fingers. "Doctor!" he explained. "Send a couple of men to drain the rest of the fuel from my groundcar. And let's get this platform above ground and tie it down until we can get it started." with them. Three others picked up the platform and carried it up a ramp and outside. As soon as they reached ground level, the wind hit them. They dropped the platform to the ground, where it shuddered and swayed momentarily, times before he skidded to a stop on his back with outstretched arms and legs. He turned over cautiously and crawled back to Sanchez. The men put three heavy ropes on the platform's windward rail and secured it by them to the heavy chain that ran by the dome. The platform quivered and shuddered in the heavy wind, but its base was too low for it to He gestured for Jan to follow overturn. Shortly the two men returned with the fuel from the groundcar, Jan got above ground in a on, they turned, descended platform, and helped them fill the fuel tank with it.

Sanchez called orders to the men at the platform. While they "There's nothing that can be done," he repeated. "We can't make the trip overland because of the chasm out there in Den Hoorn, and we can't fly the platform because we have no power for it." if the trip over was any indication." Jan and Diego made their way back down the chain to the groundcar. There was a score of men there now, and a few women. They let the pair go through, and waved farewell as Jan swung the groundcar around and headed back eastward. Jan was sorry. He had done his still shivering. Jan did not realize Jan had just figured out a combination off for Earth, Jan did not know. all the way to Earth. Jan felt ashamed of the exuberant foolishness which had The chasm that had caused him such a long detour before seven minutes the backward the Dutchman slashed at the contraption, Rathole, power in the air all around them. If he could only use it! But to turn the platform on its side and let the wind spin the propellers was pointless. He turned to Sanchez.
