Vaguely, Ron wondered if these growths were something from Titan's tremendously ancient past, when Saturn had been a hot, youthful world, acting as a warming sun to its satellites. Some vestige of plant-life preserved here through the frozen eons. But why should such vegetation appear suddenly, now? Why hadn't its seeds sprouted as soon as Leiccsenland had been thawed, years ago, if they had existed? And then, with a sudden inspiration, Ron saw part of the truth. The brown, dusty stuff that had filled the hold of the _Barbarian_! Seed of some kind! Arne Reynaud's plan! But what in the name of sense could it all be about? Those growths out there weren't poison, evidently! Ron saw both Callistans and Earthians handle them with impunity! What harm could they ever be to the invaders? None! With a cold wave of despair, Ron reached this inevitable conclusion. So this, then, was the final disillusionment! Reynaud had been a crackpot after all! Like many a hare-brained inventor, he had dreamed only nonsense! And the struggle to carry out his wild scheme had been utterly wasted! Ron Leiccsen sank into black dejection. Once, beyond the wall of the great factory, he heard a flurry of hisses. Heat-guns and pistols being discharged. And then human screams of agony--and silence. Stealing another moment to peer from the window, he saw furry guards reloading their weapons, after the brief, murderous action. On the ground, too far off for their personal identity to be revealed, were burnt and crumpled human corpses. A group of colonists, maddened by their heartless overlords, must have tried to escape to the hills. And this was their end. Had Anna Charles been among them? Quite possibly. Reckless and brave and impatient as she was, it was almost probable. And Ron Leiccsen couldn't have found it in his heart to blame her. He would have been among that bunch of rebels, too, if he hadn't been imprisoned here. Grief struck home, until his eyes misted and his throat ached. Arruj came into his cubicle not long afterward. "Very little more time for you to live, Eart'man," he announced gleefully. "When our city built, we kill all Eart'folk. No good! Much trouble! Always try revolt! All things from Eart' no good! Except sun-ray towers. Plants from Eart' no good! Don't like Eart' plants. Corn, grain, trees, everyt'ing! Look ugly. No use. We root up--destroy!" Arruj emphasized his hatred of all that was terrestrial by striking Ron across the back with his metal staff. Blood oozed, dying the filthy tatters of Ron's shirt.
