The semanticist had evidently made a good guess in alien psychology, for no hostile move was made toward the machine. The natives lay there studying it, making occasional guarded gestures to each other. They stiffened as the next picture flipped into view. It was a Terrestrial family with two children. It was the picture Stuart kept beside his bunk, and was the best thing he could think of to put across the concept of a peaceful people. Still no hostile move. No sounds, either, except the background chirping and jabbering of other animals. Anxiously, Stuart fussed with his controls. He flipped to the next picture and a dozen after that without getting an audible response. The natives were shown views of Terrestrial life, New York and the space-port, the _Special Agent_, and two views of the receding Earth. Then the linguist tried one of his sketches. It showed a globular ship, such as the Invaders were believed to have used, attacking the Terrestrial ship. In the following sketches, the Earth ship was damaged, but managed to destroy the other. One of the natives was evidently jolted into comment at this point. "Aru!" came distinctly over the loudspeaker. Stuart immediately murmured "Picture Fifteen" in Universal Speech into his microphone. He beamed at Gordon, relaxed a little, and hit the sequence button again. The next set of pictures showed the approach to Azura, the landing, and Rogers' kindly treatment of the monkey-rats. Again a comment came from the middle native, evidently younger and less well-trained. This time he uttered several syllables, which the cephaloid duly absorbed. The rear native thwacked him across the back angrily. Stuart bounced in his seat with silent glee. He made microscopic adjustments to the analyzer and continued the show. Behind him, the door opened quietly. Rogers came in with some breakfast for Gordon. The scout raised his eyebrows inquiringly; the chief winked and nodded at the screen, holding up a hand in the "okay" gesture. Stuart looked around at them, his finger hesitating over the sequence button. He shut off his mike for a moment. "This is one of the parts I'm dubious about. We swing into our sales talk here. Man sees native, puts down gun, and approaches peacefully. Then they exchange gifts." He pushed the stud thoughtfully. "If the response to this is favorable, do you think we ought to go ahead with the rest?" The chief frowned. "Sure. Why not?" "Well ... I suppose it would be foolish to stop now. I don't have enough material yet to prepare a verbal message, and they seem to be understanding this one anyway. On the other hand ... they might not like this. It shows us helping them to rebuild a city, and giving them weapons." He lit a cigarette and hit the button again. "They might wonder what we want in return."
