Here and there a gossamer suspension bridge dotted with foot passengers flung across the chasm and the air was webbed with slender cables.

A cliff of edifice hung above him, he perceived as he glanced upward, and the opposite facade was grey and dim and broken by great archings, circular perforations, balconies, buttresses, turret projections, myriads of vast windows, and an intricate scheme of architectural relief.

Athwart these ran inscriptions horizontally and obliquely in an unfamiliar lettering.
Here and there close to the roof cables of a peculiar stoutness were fastened, and drooped in a steep curve to circular openings on the opposite side of the space, and even as Graham noted these a remote and tiny figure of a man clad in pale blue arrested his attention.

This little figure was far overhead across the space beside the higher fastening of one of these festoons, hanging forward from a little ledge of masonry and handling some well-nigh invisible strings dependent from the line.

Then suddenly, with a swoop that sent Graham's heart into his mouth, this man had rushed down the curve and vanished through a round opening on the hither side of the way.
