"Natives?" Watts considered. "Yes, there's some kind of aborigines living out there." He waved vaguely toward the window. "What are they like? Have you seen them?" "Yes, I've seen them. At least, I saw them when we first came here. They hung around for a while, watching us, then after a time they disappeared." "Did they die off? Diseases of some kind?" "No. They just—just disappeared. Into their forest. They're still there, someplace." "What kind of people are they?" "Well, the story is that they're originally from Mars. They don't look much like Martians, though. They're dark, a kind of coppery color. Thin. Very agile, in their own way. They hunt and fish. No written language. We don't pay much attention to them." "I see." Harris paused. "Chief, have you ever heard of anything called—The Pipers?" "The Pipers?" Watts frowned. "No. Why?" "The patients mentioned something called The Pipers. According to Bradshaw, the Pipers taught him to become a plant. He learned it from them, a kind of teaching." "The Pipers. What are they?" "I don't know," Harris admitted. "I thought maybe you might know. My first assumption, of course, was that they're the natives. But now I'm not so sure, not after hearing your description of them." "The natives are primitive savages. They don't have anything to teach anybody, especially a top-flight biologist." Harris hesitated. "Chief, I'd like to go into the woods and look around. Is that possible?" "Certainly. I can arrange it for you. I'll give you one of the men to show you around." "I'd rather go alone. Is there any danger?" "No, none that I know of. Except—" "Except the Pipers," Harris finished. "I know. Well, there's only one way to find them, and that's it. I'll have to take my chances." "If you walk in a straight line," Chief Watts said, "you'll find yourself back at the Garrison in about six hours. It's a damn small asteroid. There's a couple of streams and lakes, so don't fall in."
