"I can do that," Ger said excitedly. He started to flow into the shape of a Dog. "No, wait," Pid said. "We'll spend the rest of the day thinking it over. This is too important to rush into." Ger subsided sulkily. "Come on, let's move back," Pid said. He and Ger started into the woods. Then he remembered Ilg. "Ilg?" he called softly. There was no answer. "Ilg!" "What? Oh, yes," an oak tree said, and melted into a bush. "Sorry. What were you saying?" "We're moving back," Pid said. "Were you, by any chance, Thinking?" "Oh, no," Ilg assured him. "Just resting." Pid let it go at that. There was too much else to worry about. hey discussed it for the rest of the day, hidden in the deepest part of the woods. The only alternatives seemed to be Man or Dog. A Tree couldn't walk past the gates, since that was not in the nature of trees. Nor could anything else, and escape notice. Going as a Man seemed too risky. They decided that Ger would sally out in the morning as a Dog. "Now get some sleep," Pid said. Obediently his two crewmen flattened out, going immediately Shapeless. But Pid had a more difficult time. Everything looked too easy. Why wasn't the atomic installation better guarded? Certainly the Men must have learned something from the expeditions they had captured in the past. Or had they killed them without asking any questions? You couldn't tell what an alien would do. Was that open gate a trap? Wearily he flowed into a comfortable position on the lumpy ground. Then he pulled himself together hastily.
