He awoke at dawn with the din of bird song in his ears. Jill opened her eyes at almost the same instant. She smiled at him and tried to get up. She was stiff and sore from the hardness of the ground on which she'd slept. But it was a new day, and there was breakfast. It was porcupine cooked the night before. "Somehow," said Jill as she nibbled at a bone, "somehow I feel more cheerful than I did." "That's a mistake," Lockley told her. "Start out with a few premonitions and the day improves as they turn out wrong. But if you start out hoping, the day ends miserably with most of your hopes denied." "You've got premonitions?" she asked. "Definitely," he said. It was true. As yet he knew nothing of last night's temporary occupation of a human town, but he believed he knew how the terror beam worked even if he couldn't figure out a way to generate it. He could imagine no defense against it. But if Jill had awakened feeling cheerful, there was no reason to depress her. She'd have reason enough to be dejected later, beginning with proof of Vale's death and going on from there. "We might listen to the news," she suggested. "A premonition or two might be ruled out right away!" Silently, he turned on the little radio. Automatically, he set it for the lowest volume they could hear distinctly. The main item in the news was a baldly factual but toned-down report of the thing from the lake which had left the park and examined a small human town in detail and then had returned to the Park. There were reports of peculiar hoofprints found where the invaders had been. They were not the hoofprints of any earthly animal. There was an optimistic report from the scientists at work on the problem of the beam. Someone had come up with an idea and some calculations which seemed to promise that the beam would presently be duplicated. Once it was duplicated, of course a way to neutralize it could be found. Lockley grunted. The broadcast was enthusiastic in its comments on the scientists. It talked gobbledegook which sounded as if it meant something but was actually nonsense. It barely touched on the fact that human beings were now ordered out of a much larger space than had been evacuated before. There was a statement from an important official that panic buying of food was both unnecessary and unwise. Lockley grunted again when the newscast ended. "The idea that anything that can be duplicated can be canceled," he announced gloomily, "is unfortunately rot. We can duplicate sounds, but there's no way to make them cancel out! Not accurately!" Jill had eaten a substantial part of the porcupine while the newscast was on. It was not a satisfying breakfast, but it cheered her immensely after two days of near-starvation. "But," she observed, "maybe that won't apply to this business when you report what you know. It's not likely that anybody else has stood just outside a beam and made tests of what it's like and how it's aimed and so on."
