They had no symptoms of distress afterward. Other fruits were less satisfactory. Of the samples which the skin-test said were non-poisonous, one was acrid and astringent, and two others had no taste except that of greenness--practically the taste of any leaf one might chew. "I suppose," said Cochrane wryly, as they headed back toward the ash-clearing at nightfall, "we've got to find out if the animals can be eaten." Babs nodded matter-of-factly. "Yes. Tonight I'm taking part of the watch. As you remarked this morning, we're in this together." He looked at her sharply, and she flushed. "I mean it!" she said doggedly. "I'm watching part of the night!" He was desperately tired. His muscles were not yet back to normal after the low gravity on the moon. She'd had more rest than he. He had to let her help. But there was embarrassment between them because it looked as if they would have to spend the rest of their lives together, and they had not made the decision. It had been made for them. And they had not acknowledged it yet. When they reached the clearing, Cochrane began to drag new logs toward the central place where much of last night's supply of fuel remained. Matter-of-factly, Babs began to haul stuff with him. He said vexedly: "Quit it! I've already been realizing how little I know about the things we're going to need to survive! Let me fool myself about masculine strength, anyhow!" She smiled at him, a very little. But she went obediently to the fire to experiment with cookery of the one palatable variety of fruit from this planet's trees. He drove himself to bring more wood than before. When he settled down she said absorbedly: "Try this, Jed." Then she flushed hotly because she'd inadvertently used his familiar name. But she extended something that was toasted and not too much burned. He ate, with weariness sweeping over him like a wave. The cooked fruit was almost a normal food, but it did need salt. There would be trouble finding salt on this planet. The water that should be in the seas was frozen in the glaciers. Salt would not have been leached out of the soil and gathered in the seas. It would be a serious problem. But Cochrane was very tired indeed. "I'll take the first two hours," said Babs briskly. "Then I'll wake you." He showed her how to use the weapon. He meant to let himself drift quietly off to sleep, acting as if he had a little trouble going off. But he didn't. He lay down, and the next thing he knew Babs was shaking him violently. In the first dazed instant when he opened his eyes he thought they were surrounded by forest fire. But it wasn't that. It was dawn, and Babs had let him sleep the whole night through, and the sky was golden-yellow from one horizon to the other. More, he heard the now-familiar cries of creatures in the forest. But also he heard a roaring sound, very thin and far away, which could only be one thing. "Jed! Jed! Get up! Quick! The ship's coming back! The ship! We've got to move!"
