The Bell lurched alarmingly through the underMantle, unbalanced by the mass of Corestuff clinging to its side. Farr tried to judge their ascent, but he couldn't separate genuine indications of their rise to the light — the sensations in his belly, a lightening of the gloom in the small windows — from optimistic imagination. He gazed anxiously at the bruised-purple glow in the windows, unable to take any of the food Bzya offered him from a small locker set in the hull of the Bell.

The Bell shuddered under a fresh impact. Farr clung to his pole. There was a grinding noise, and the clumsy little craft shuddered to a halt.

Farr resisted the temptation to close his eyes and curl up. What now? What else can they throw at me?

He felt Bzya's rough fingertips on his shoulders. "It's all right, lad. That's a sign that we're nearly home."

"What was it?"

"That was our berg, scraping against the Spine. We're only a meter or so below Parz itself now."

Hosch hauled at a lever on the control panel, grunting with the effort; the hum Farr had learned to associate with the currents supplying the Bell's protective magnetic field decreased in intensity. Hosch turned to him, his mood evidently swinging toward its calm, sly pole. "Your buddy here is half-right. But we aren't safe yet. Not by a long way."

In fact this was one of the most dangerous parts of the mission. The berg, rattling against the Spine, could easily sever their cables or damage the Spine itself.

"So," Hosch said silkily, "one of us has to go outside and do some work."

"What work?"

"Wrap ropes around the berg. Lash it to the Bell," Bzya said gently. "That's all. Stops the berg from shaking loose, and protects the cables from collisions with the Corestuff."

Hosch was staring at Farr.

Bzya held up his huge hands. "No," he said. "Hosch, you can't be serious. You can't send the boy out there."

"I've never been more serious," Hosch said. "As you've both been telling me, the boy won't last five heartbeats down here unless he learns the trade. And there's only one way to do that, isn't there?"

Bzya made to protest, but Farr stopped him. "It's all right, Bzya. I'm not afraid. He's probably right, anyway."

Bzya said, "Listen to me. If you were not afraid you would be a fool, or dead. Fear keeps your eyecups open and clean."

"Ropes in that locker," Hosch said, pointing.

Bzya started to haul out the tightly packed, thick ropes; soon the little cabin seemed filled with the stuff. "And you," Hosch snapped at Farr. "Get the hatch open."

Farr looked through the window. The Air — if it could be called Air, this deep — was purple, almost Sea-like. He was still, after all, a full meter — a hundred thousand mansheights — below Parz.

He felt the sole of a foot in his back. "Get on with it," Hosch growled. "It won't kill you. Probably."
