"There's nothing to do until morning." Unconsciously, Cochrane looked grim. "Then there'll be plenty. Food, for one thing. We don't know, actually, whether or not there's anything really edible on this planet--for us. It could be that there are fruits or possibly stalks or leaves that would be nourishing. Only--we don't know which is which. We have to be careful. We might pick something like poison ivy!" Babs said: "But the ship will come back!" "Of course," agreed Cochrane. "But it may take them some time to find us. This is a pretty big planet, you know." He estimated his supply of burnable stuff. He improved the rampart he had made at first. Babs stared at him. After four or five minutes he stepped back. "You can lean against this," he explained. "You can watch the fire quite comfortably. And it's a sort of wall. The fire will light one side of you and the wall will feel comforting behind you when you get sleepy." Babs nodded. She swallowed. "I--think I see what you mean when you say they may have trouble finding us, because this planet is so large." Cochrane nodded reluctantly. "Of course there's this burned-off space for a marker," he observed cheerfully. "But it could take several days for them to see it." Babs swallowed again. She said carefully: "The--ship can't hover like a helicopter, to search. You said so. It doesn't have fuel enough. They can't really search for us at all! The only way to make a real search would be to go back to Earth and--bring back helicopters and fuel for them and men to fly them.... Isn't that right?" "Not necessarily. But we do have to figure on a matter of--well--two or three days as a possibility." Babs moistened her lips and he said quickly: "I did a show once about some miners lost in a wilderness. A period show. In it, they knew that part of their food was poisoned. They didn't know what. They had to have all their food. And of course they didn't have laboratories with which to test for poison." Babs eyed him oddly. "They bandaged their arms," said Cochrane, "and put scraps of the different foodstuffs under the bandages. The one that was poisonous showed. It affected the skin. Like an allergy-test. I'll try that trick in the morning when there's light to pick samples by. There are berries and stuff. There must be fruits. A few hours should test them." Babs said without intonation: "And we can watch what the animals eat." Cochrane nodded gravely. Animals on Earth can live on things that--to put it mildly--humans do not find satisfying. Grass, for example. But it was good for Babs to think of cheering things right now. There would be plenty of discouragement to contemplate later.
