The general level of the roof seemed about three hundred feet above the ground, and the summits of the domes some fifty feet higher.
The houses, which were all square, were, as a rule, about forty feet high.

The roofs were covered with gardens and shrubberies, from which creepers, bearing brillantly coloured leaves and flowers, hung down about the windows in carefully arranged festoons.

The walls were composed of the opaque mica-like glass, relieved by pillars and arched doorways and windows.

The windows, of French form, were of clear glass, and mostly stood open.

A sweet, cool zephyr of hardly perceptible strength appeared to be blowing along the street and over the house-tops and in the vast airy space above the roofs.
Brightly plumaged birds were flitting about among the branches of giant trees, and keeping up a perpetual chorus of song.
Presently their host touched Redgrave on the shoulder and pointed to a four-wheeled car of light framework and exquisite design, containing seats for four besides the driver, or guide, who sat behind.
