The elderly one approached the Earthman and held out his tentacles to the sides. It seemed to mean something. There was a short, tense silence. "Of course!" exclaimed Stuart to himself. "The gesture of peaceful intent: showing the absence of weapons!" He held up his hands, likewise empty, and repeated his speech. There were murmurs of "Aru!" around him. Unobtrusive weapons were unobtrusively lowered. Sketching materials were brought to the official: sheets of something like parchment, and a reed which exuded an inky substance through a fine hole. Two blocks of what seemed to be extraordinarily soft wood were carried in; the official sat down, somewhat in human fashion, and motioned the language expert to do likewise. The "conversation" lasted almost two hours. Stuart, by sketching and using a few words, explained his mission. The natives seemed to understand; judging by their awareness of the outer universe, they had considerable scientific knowledge. He guessed, though, that their technology was more biological than mechanical. They knew where the Invaders were from, what they had looked like, and how some of their mechanisms had operated. But Azuran culture, never warlike, had been unable to strike back, and had been so badly smashed that there had been no opportunity to use the captured knowledge. "They nearly destroyed my people," explained the official with words and pictures. "We were many millions. Now only thousands. We saved what we could and hid underground, scattered. For five years we have struggled to stay alive. Now we are regaining our strength and can think of building again. But always we must be ready for the Invaders. They killed for nothing or for amusement. Took nothing except specimens; apparently they wanted nothing here but sport. They simply attacked without warning one day, all over the planet, and hunted us for fifty-four days. Then they disappeared. We caught a few live ones outside their ships by trickery, and we captured two small ships the same way. But in our difficulty we have had little time to investigate the ships." "Where are the captured creatures?" asked Stuart. "Oh, they did not live long." The other's manner did not indicate regret. "They needed high temperature and a special atmosphere to stay alive, and of course we had inadequate means to care for them. We made very thorough biological studies of them, however." He shook his tentacles, as if in disgust. "They were remarkably unpleasant. Colorless, and gritty to the touch. Completely hateful. They used to throw dissected specimens of our people out of their ships; sometimes live people were dropped." * * * * *
