The steam carts suddenly swerved, one after the other, ran wildly into the side of a building, and turned over. The jeep roared past them, raced across the last hundred feet of city paving and out onto the desert. Haines had to slow down to navigate safely the uneven layers of barren soil, rock and sand. Burl holstered his gun and reached across for one of the abandoned walkie-talkies.
In the excitement of their exit, none had noticed the change in the Martian scenery. But now it occurred to Burl that the day was distinctly lighter, and he fancied the Sun—small though it was—felt warmer. The Sun-tap demolished, this was to be expected, and by the same token, radio communication should now be practical.
Sure enough, he got Lockhart's voice at once. Hastily, he warned the commander of what had happened.
As they drew nearer the Magellan, the great spaceship lowered toward the ground and let down its grapples and ladders. Burl saw that there was no time to be lost. A stream of Martians and steam carts was pouring out of the city on their trail.
They reached the spaceship and slammed to a halt. The men leaped out. Burl and Russ lifted Boulton's unconscious body from the jeep and, between them, managed to hoist him awkwardly up the dangling rope ladder.
The others hooked grapples onto the jeep, and when it was secure, leaped for safety themselves.
As the first of the Martian steam carts was almost on them, the Magellan lifted into the air. It rose high above the surface and swung off into the desert. The Martians drew to a halt. Burl, looking down from the doorway of the cargo hatch, could see them milling aimlessly around. None, he noticed, ever glanced up. Air flight, apparently, was an inconceivable phenomenon to them.
After the jeep had been pulled into the cargo hold and secured, the outer ports were sealed. When everyone was safely in the inner sphere, the Magellan drew away from Mars and started on the next lap of its long mission.
Boulton was carefully examined. Nothing could be made of his condition. He seemed to bear no physical hurt, although he slept on. He was placed in his bunk, and there he rested, breathing slowly, temperature normal, dormant.
The life of the spaceship resumed, for the time being, without him. The next port of call was Jupiter, and that presented problems of its own. Between Mars and Jupiter was the great asteroid belt, a region of many thousands of tiny planetoids, ranging in size from worldlets of two or three hundred miles in diameter down to rocks the size of footballs. "The debris of an exploded planet," was the comment Russ made to Burl. "That's the most likely explanation. Anyway," he added, "there seems to be no Sun-tap station on any of them. The next one is beyond the asteroids, in Jupiter's orbit."
