-This ain’t nothing, Uzman says to Judah. -We got more coming. He harangues the iron council at night in the headlights. Ann-Hari takes his side, and though the stokers and the engineers complain that they can see their stocks of coal dwindling, though the workers are exhausted, the council agrees to more speed. The tracks are laid all night and day, by men and women in an anaesthesia of tiredness, dreaming while they swing their hammers.

The iron road eats the miles. At night the train’s moving illumination makes the rockforms shift, as if they are trying to get away. Insects and things the size of insects perform a rhythm of their bodies on lantern glass, become flame-bursts where they find a way inside. The train is a line of dark light on the night plains.

The earth feels uneasy. The council tenses. Newcomers are targeted, are told they are spies. Judah helps an intervening crowd stop one terror-struck angry man beating a fReemade newcomer to death, and in their admonishments and the counter-beating they give him, neither Judah nor any other person acknowledges that the man might be right, that there are spies with them.

At the edge of the plain is the landform they want. A smokestone range. The unmoving brume shapes grow slowly clearer. A posse treks on to blast a path through the solid mist.

The perpetual train is a fortress. Its strange guntower is scabbed with new metal. All the councillors carry clubs, sharpen them into spears, splints of stone with rag handles. Crude and eccentric rifles. The council is waiting.

Inside Judah the thing shifts, and he knows that though it is not the time yet, he will leave.

They pass the outskirts of the smokestone hills. An abrupt change of landscape into something dreamish and unsettling, where wisp-shapes rise in basalt-hard congelation, clotted clouds on which the tough fauna of the smokestone run. There are plumes, fountainheads where geysers of smoke have poured and set near-instantly. The roadbed goes between them, through a solfatara of vented gases.

The iron council graders have blasted passage. The elegance of set smokestone is interrupted with the base simplicity of jag-edged holes.

Mostly the stonemass is caught as billows, but there are pillars that corkscrew faintly and become wisps at their peak, where leaks of smokestone have gusted in very still air. The train passes under arcs where currents have blown smokestone up from the ground and down again.
