Past the anchor-band, the Skin unfolded before Farr's gaze. He'd expected the Skinscape to be featureless, uniform, except for the random blemishes of its construction. But it was much too huge to allow such uniformity, he soon realized. As they climbed toward the City's equator, toward the Upside areas, the huge cargo ports and public Air-shafts became more sparse, to be replaced by smaller, tidier doorways evidently meant for humans and Air-cars, and by small portals which must be windows or light-shafts for private dwellings. A man leaned out of a window and hurled out a bowl of what looked like sewage; the stuff sparkled as it dispersed. Cris cupped his hands around his mouth and called down a greeting. The man — squat and yellow-haired — peered out into the sky, startled. When he spotted the boys he shook his fist at them, shouting something angry but indistinguishable. Cris yelled abuse back, and Farr joined in, shaking his fist in return. He laughed, exhilarated by this display of disrespect; he felt free, young, healthy, released from the confines of the City, and the comparison with the sour old man in his windowed cell made his condition all the sweeter.

They flew past an area of hull covered by a crude framework, a rectangular lattice of wood. Behind the framework the Skin was broken open, exposing small chambers within the City lit by dim green wood-lamps. Huge sections of wooden paneling drifted in the Air outside the City, attached loosely to the framework by lengths of rope; men and women clambered over the framework, hauling at the panels and hammering them into place in the gaps in the Skin.

"Repairs," said Cris in uninterested response to Farr's question. "They go on all the time. My father says the City's never really been finished; there's always some section of it that needs rebuilding."

They arced high across a comparatively blank area of hull, unblemished by door, window or port. Farr looked back to see the last small portals recede over the City's tightly curving horizon, and soon there was no break in the Skin in sight. Cris Surfed on in silence, subdued. Moving over this featureless Skinscape Farr felt absurdly as if he had been rejected by the City, thrown out and shunned — as if it had turned its back.
