Now there seemed to be a building with odd architecture, or perhaps a pavilion that was mostly a roof supported by a central pylon.

Spindle-shaped lift cars rode up a central black pylon.

"They shortened the central pylon by twenty percent to compensate."

The system allows the central pylons to support the weight of the copper.

The cable-car was ten yards away from the central pylon.

The ascending car on the other cable was now almost as close to the central pylon as his own.

It was now late enough that he felt he could venture higher, up the central pylon to the saucer itself.

It drifted gracefully around a tower and landed on the point of a single central pylon.

With luck, his own cable-car might be the first to arrive at the central pylon.
