The location of an objective upon the great world of Trantor presents a problem unique in the Galaxy. There are no continents or oceans to locate from a thousand miles distance. There are no rivers, lakes, and islands to catch sight of through the cloud rifts.

The metal-covered world was ?had been ?one colossal city, and only the old Imperial palace could be identified readily from outer space by a stranger. The Bayta circled the world at almost air-car height in repeated painful search.

From polar regions, where the icy coating of the metal spires were somber evidence of the breakdown or neglect of the weather-conditioning machinery, they worked southwards. Occasionally they could experiment with the correlations ?or presumable correlations)?between what they saw and what the inadequate map obtained at Neotrantor showed.

But it was unmistakable when it came. The gap in the metal coat of the planet was fifty miles. The unusual greenery spread over hundreds of square miles, inclosing the mighty grace of the ancient Imperial residences.

The Bayta hovered and slowly oriented itself. There were only the huge supercauseways to guide them. Long straight arrows on the map, smooth, gleaming ribbons there below them.

What the map indicated to be the University area was reached by dead reckoning, and upon the flat area of what once must have been a busy landing-field, the ship lowered itself.

It was only as they submerged into the welter of metal that the smooth beauty apparent from the air dissolved into the broken, twisted near-wreckage that had been left in the wake of the Sack. Spires were truncated, smooth walls gouted and twisted, and just for an instant there was the glimpse of a shaven area of earth ?perhaps several hundred acres in extent ?dark and plowed.

Lee Senter waited as the ship settled downward cautiously. It was a strange ship, not from Neotrantor, and inwardly he sighed. Strange ships and confused dealings with the men of outer space could mean the end of the short days of peace, a return to the old grandiose times of death and battle. Senter was leader of the group; the old books were in his charge and he had read of those old days. He did not want them.

Perhaps ten minutes spent themselves as the strange ship came down to nestle upon the flatness, but long memories telescoped themselves in that time. There was first the great farm of his childhood ?that remained in his mind merely as busy crowds of people. Then there was the trek of the young families to new lands. He was ten, then; an only child, puzzled, and frightened.

Then the new buildings; the great metal slabs to be uprooted and tom aside; the exposed soil to be turned, and freshened, and invigorated; neighboring buildings to be tom down and leveled; others to be transformed to living quarters.

There were crops to be grown and harvested; peaceful relations with neighboring farms to be established?

There was growth and expansion, and the quiet efficiency of self-rule. There was the coming of a new generation of hard, little youngsters born to the soil. There was the great day when he was chosen leader of the Group and for the first time since his eighteenth birthday he did not shave and saw the first stubble of his Leader's Beard appear.

And now the Galaxy might intrude and put an end to the brief idyll of isolation?

The ship landed. He watched wordlessly as the port opened. Four emerged, cautious and watchful. There were three men, varied, old, young, thin and beaked. And a woman striding among them like an equal. His hand left the two ............
