As if the scene were a film being shut off, it blinked out Through the door which had been in Sam's birthplace and now was the door of the bamboo hut, another figure entered. It was momentarily silhouetted by the bright starlight, then slid into the shadows. Sam closed his eyes and steeled himself for another frightening experience. He groaned and wished he had not taken the dreamgum. Yet he knew that under the terror was a thread of delight. He hated and enjoyed this. The birth-drama was a fantasy, created by him to explain why he was the kind of man he was. But what was this shadowy figure moving silently and intently as death? From what deep cavern in his mind came this creature?

A baritone voice spoke. "Sam Clemens! Do not be alarmed! I am not here to harm you! I come to help you!"

"And what do you want in repayment for your help?" Sam said.

The man chuckled and said, "You're the kind of human being I like. I chose well." "You mean I chose you to choose me," Sam replied.

There was a pause of several seconds, and then the man said, "I see. You think I'm another fantasy inspired by the gum. I'm not. Touch me."

"What for?" Sam said. "As a gum-inspired fantasy, you should know that you can be felt as well as seen and heard. State your business."

"Entirely? That would take too long. And I don't dare take much time with you. There are others in this area who might notice. That would be too bad for me, since they are very suspicious. They know there is a traitor among them, but they don't have the slightest idea who it could be." "Others? They?" Sam answered. "They—we Ethicals—are doing field work in this area

ow," the figure said. "This is a unique situation, the first time that a completely unhomogenized assortment of humans has been thrown together. It presents a rare chance for study, and we are recording everything. I'm here as chief administrator, since I'm one of The Twelve."

"I'll have to figure you out after I wake up," Sam replied.

"You are awake, and I exist I have objective reality. And, I repeat, I don't have much time."

Sam started to sit up but was pushed back by a hand which somehow communicated a sense of great power, muscular and mental. Sam shivered upon feeling it. "You're one of Them," he whispered. "One of Them!"

He gave up his idea of seizing the man and calling for help.

"Of them, but not with them," the man said. "I'm with you human beings, and I intend to see that my people do not complete their filthy project. I have a plan, but a plan that will take much time, much patience, a slow and careful, devious development. I have contacted three humans now; you are the fourth. They are aware of parts of the plan but not all of it. If any one of them should be revealed and interrogated, he could tell the Ethicals only a little. The plan must unfold slowly and everything must appear accidental. "Just as the meteorite must appear accidental."

Sam did start to sit up then but caught himself before the hand touched him. "It was no accident?"

"No. I have known for some time of your dream of building a Riverboat and going to the end of The River. It would be impossible without iron. So I deflected the meteorite to bring its orbit within this planet's grip and cause it to crash near you. Not too near you, of course, otherwise you would have died and have been translated far from this area. There are safeguards to prevent such spatial matter from falling on the valley, but I managed to trip them out just long enough for the meteor to get through. Unfortunately, the guardians almost got to the repulsion system in time. When the system went back into action, its effect caused the meteorite to go off the course I'd planned. As a result, we—I mean you—almost got killed. It was just luck that you weren't. But then I've found out that what you call luck is on my side." "Then the falling star... ?" "Is a deliberately felled star, yes."

Sam thought, if he knows so much about me, he must be one of the crew of the Dreyrugr. Unless he's able to make himself invisible. That isn't impossible. That egg-shaped ship I saw in the air was invisible; I only saw it because it was for some reason made visible very briefly. Maybe the lightning interfered with the apparatus that makes the ship invisible.

Then, What am I thinking? This is just another dreamgum fantasy.

The man said, "One of their agents is nearby! Listen carefully! The meteorite wasn't removed because we didn't have time. At least, that was my decision. It's buried under the plains and foothills ten miles from here. Go ten grailstones downRiver.

"You'll be on the perimeter of the original crater, where several large masses and many small pieces are buried. Start digging. The rest is up to you. I'll help you when I can, but I can't do anything obvious."

Sam's heart was beating so hard his own voice sounded muted. "Why do you want me to build a boat?"

"You'll find out in time. For the present, be happy that you've been given what you need. Listen! There's a huge deposit of bauxite only five miles farther up, under the surface of the mountains, near the base. And near it is a small lode of platinum and two miles up from it, cinnabar." "Bauxite? Platinum?" "You fool!"

There was the sound of hard breathing. Sam could almost hear the man's internal struggle to control his disgust and fury. Then, calmly, "You'll need bauxite for aluminum and platinum for a catalyst for the many things you'll have in your boat. I haven't got time to explain. There are several engineers in this area who'll tell you what to do with the minerals. I must go. He's getting closer! Just do what I say. And, oh, yes, there's flint thirty miles upRiver!"

"But..." Sam said. The man was silhouetted briefly and was gone. Sam rose unsteadily and went to the door. Fires were still blazing on the banks, and small figures were capering in front of them. The stranger was gone. Sam went around to the back of the hut but there was no one there. He looked up at the sky, pale with great gas sheets and bright knots of white, blue, red and yellow stars. He had hopes he might catch a glimpse of a vehicle winking from visibility to invisibility. But there was nothing.

On returning to the hut, he was startled by a huge figure standing dark and immobile before his door. His heart hammering, he said, "Joe?"

"Yeah," answered the bass drum voice. Joe advanced to nun and said, "There'th been thomone not human here. I can thmell him. He got a funny thtink, different than you humanth got. You know, it remindth me ..."

He was silent for a while. Sam waited, knowing that the ponderous stone wheels were grinding out the flour of thought. Then Joe said, "Veil, I'll be damned!" "What is it, Joe?"

"It'th been tho long ago, it happened on Earth, you know, thometime before I got killed there. No, it couldn't be. Jethuth Chritht, if vhat you thay ith true about how long ago I lived, it mutht've been maybe a hundred thouthand yearth ago!" "Come on, Joe, don't leave me hanging up in the air."

"Veil, you ain't going to believe thith. But you got to remember that my nothe hath a memory, too."

"It ought to, it's bigger than your brain," Sam said. "Out with it, or are you trying to kill me with frustrated curiosity?"

"All right, Tham. I vath on the track of a vifthangkruilth tribethman, they lived about ten mileth from uth on the other thide of a big hill that looked like ..." "Never mind the details, Joe," Sam snapped.

"Veil, it vath late in the day and I knew I vath getting clothe to my enemy becauthe hith printth were tho frethh. And then I heard a noithe that made me think maybe the guy I vath following had backtracked on me and I vath going to get hith club thyoved all the vay up instead of vithevertha. Tho I dropped to the ground and crawled tvardth the noithe. And gueth vhat I thaw? Great Thcott, vhy didn't I ever tell you thith before? Vat a dummy I am!"
