disgrace to scream in the burner. But he wasn't screaming now. He lay there for ten minutes, his jaw clamped, while the twitching subsided and his nervous system regained its usual co-ordination. The burner did no actual physical damage; it wasn't good economics for an Executive to allow his men to be hurt in any physical manner. It took a very little actual amount of energy applied to the nerve endings to make them undergo the complex electrochemical reaction that made them send those screaming messages to the brain and spine. There was less total damage done to the nerves than a good all-night binge would do to a normal human being. But the effect on the mind was something else again. It was a very effective method of making a man learn almost any lesson you wanted to teach him. After a while, The Guesser shuddered once more, took a deep breath, held it for fifteen seconds, and then released it. A little later, he lifted himself up and swung his legs over the edge of his bed. He sat on the edge of the bed for a few minutes, then got up and got dressed in his best uniform. After all, the captain hadn't said anything about restricting him to the ship, and he had never been to Viornis before. Besides, a couple of drinks might make him feel better. There were better planets in the galaxy, he decided two hours later. Thousands of them. For one thing, it was a small, but dense world, with a surface gravity of one point two standard gees—not enough to be disabling, but enough to make a man feel sluggish. For another, its main export was farm products: there were very few large towns on Viornis, and no center of population that could really be called a city. Even here, at the spaceport, the busiest and largest town on the planet, the population was less than a million. It was a "new" world, with a history that didn't stretch back more than two centuries. With the careful population control exercised by the ruling Execs, it would probably remain small and provincial for another half millennium. The Guesser moseyed down one of the streets of Bellinberg probably named after the first Prime Executive of the planet—looking for a decent place for a spaceman to have a drink. It was evening, and the sinking of the yellow primary below the western horizon had left behind it a clear, star-filled sky that filled the air with a soft, white radiance. The streets of the town itself were
