oyce glanced at the thermometer. It still registered hundreds of degrees, though their speed had been materially reduced.
"I guess there's livable air, all right," he said. "It's pretty thick outside already."
The professor smiled. "Another theory vindicated. I was sure that Zeud, swinging on the outside of the Earth-moon-Zeud chain and hence traveling at a faster rate, would pick up most of the moon's atmosphere over a period of millions of years. Also it must have been shielded by the moon, to some extent, against the constant small atmospheric leakage most celestial globes are subject to. Just the same, when we land, we'll test conditions with a rat or two."
At a signal from him, Joyce checked their speed to four hundred miles an hour, then to two hundred, and then, as they descended below the highest rim of the circular cliffs of the crater, almost to a full stop. They floated toward the surface of Zeud, watching with breathless interest the panorama that unfolded beneath them.
They were nosing toward a spot that was being favored with the Zeudian sunrise. Sharp and clear the light rays slanted down, illuminating about half the crater's floor and leaving the cliff protected half in dim shadow.
The illuminated part of the giant pit was as bizarre as the landscape of a nightmare. There were purplish trees, immense beyond belief. There were broad, smooth pools of inky black fluid that was oily and troubled in spots as though disturbed by some moving things under the surface. There were bare, rocky patches where the stones, the long drippings of ancient lava flow, were spread like bleaching gray skeletons of monsters. And over all, rising from pools and bare ground and jungle alike, was a thin, miasmic mist.
ustained by the slow, steady exhaust of the motor, rising a little with each partly muffled explosion and sinking a little further in each interval, they settled toward a bare, lava strewn spot that appealed to Wichter as being a good landing place. With a last hiss, and a grinding jar, they grounded. Joyce opened the switch to cut off the generator.
"Now let's see what the air's like," said Wichter, lifting down a small cage in which was penned an active rat.
