"Hello, Jed! I tried the air. It's all right! At a guess, maybe a little high in oxygen. But it feels wonderfully good to breathe! And I can report that the trees are wood and the green is chlorophyll, and this is an Earth-type planet. That little smoky smell about is completely familiar—and I'm taking that as an analysis. I'm going to take a walk."

Cochrane found himself watching Babs' face. She looked enormously relieved, but even Cochrane—who was looking for something of the sort without realizing it—could not read anything but relief in her expression. She did not, for example, look admiring.

"I'll borrow one of Johnny Simms' guns," said Holden, "and take a look around. It's either perfectly safe or we're all dead anyhow. Frankly, I think it's safe. It feels right outside, Jed! It honestly feels right!"

"I'll come with you," said Cochrane, "Jones and the pilot are necessary if the ship's to get back to Earth. But we're expendable."

He went back to the control-room. Johnny Simms zestfully undertook to outfit them with arms. He made no proposal to accompany them. In twenty minutes or so, Cochrane and Holden went into the airlock and the door closed. A light came on automatically, precisely like the light in an electric refrigerator. Cochrane found his lips twitching a little as the analogy came to him. Seconds later the outer door opened, and they gazed down among the branches of tall trees. Cochrane winced. There was no railing and the height bothered him. But Holden swung out the sling. He and Cochrane descended, dangling, down fifty feet of unscarred, shining, metal hull.

The ground was still hot underfoot. Holden cast off the sling and moved toward cooler territory with an undignified haste. Cochrane followed him.

The smells were absolutely commonplace. Scorched wood. Smokiness. There were noises. Occasional cracklings from burned tree-trunks not wholly consumed. High-pitched, shrill musical notes. And in and among the smells there was an astonishing freshness in the feel of the air. Cochrane was especially apt to notice it because he had lived in a city back on Earth, and had spent four days in the moon-rocket, and then had breathed the Lunar City air for eighteen days more and had just come from the space-ship whose air was distinctly of the canned variety.

He did not notice the noise of the sling again in motion behind him. He was all eyes and ears and acute awareness of the completely strange environment. He was the more conscious of a general strangeness because he was so completely an urban product. Yet he and Holden were vastly less aware of the real strangeness about them than men of previous generations would have been. They did not notice the oddity of croaking sounds, like frogs, coming from the tree-tops. When they had threaded their way among leaning charred poles and came to green stuff underfoot and merely toasted foliage all around, Cochrane heard a sweet, high-pitched trilling which came from a half-inch hole in the ground. But he was not astonished by the place from which the trilling came. He was astonished at the sound itself.

There was a cry behind them.

"Mr. Cochrane! Doctor Holden!"
