"See there, Stettin," Seldon said as the two were taking an early evening stroll in one of Trantor's residential sectors near Streeling. The older man pointed to debris-assorted refuse jettisoned from passing groundcars or dropped by careless pedestrians-strewn along the walkway. "In the old days," Seldon continued, "you would never see litter like this. The security officers were vigilant and municipal maintenance crews provided round-the-clock upkeep of all public areas. But, most important, no one would even think of dumping his trash in such a manner. Trantor was our home; we took pride in aa. Now"-Seldon shook his head sadly, resignedly, and sighed-"it's-" He broke off abruptly.
    "You there, young man!" Seldon shouted at a ill-kempt fellow who had moments before passed them, going in the opposite direction. He was munching a treat just popped into his mouth; the wrapper had been tossed to the ground without so much as a downward glance. "Pick that up and dispose of it properly," Seldon admonished as the young man eyed him sullenly.
    "Pick it up yourself," the boy snarled and then he turned and walked away.
    "It's another sign of society's breakdown, as predicted by your psychohistory, Professor Seldon," Palver said.
    "Yes, Stettin. All around us the Empire is falling apart, piece by piece. In fact, it's already smashed-there's no turning back now. Apathy, decay, and greed have all played their parts in destroying the once-glorious Empire. And what will take its place? Why-"
    Here Seldon broke off at the sight of Palver's face. The younger man seemed to be listening intently-but not to Seldon's voice. His head was cocked to one side and his face had a far-off look. It was as if Palver were straining to hear some sound inaudible to everyone but himself.
    Suddenly he snapped back to the here and now. With an urgent glance around them, Palver took hold of Seldon's arm. "Hari, quick, we must get away. They're coming .    " And then the still evening was broken by the harsh sound of rapidly approaching footsteps. Seldon and Palver spun around, but it was too late; a band of attackers was upon them. This time, however, Hari Seldon was prepared. He immediately swung his cane in a wide arc around Palver and himself. At this, the three attackers-two boys and a girl, all teenage ruffians-laughed.
