greater part they skimmed along the surface of the sward, soaring
gracefully into the air at times to pass over a slower-going driver
ahead, or at intersections, where the north and south traffic has
the right of way and the east and west must rise above it.

From private hangars upon many a roof top fliers were darting into
the line of traffic. Gay farewells and parting admonitions mingled
with the whirring of motors and the subdued noises of the city.

Yet with all the swift movement and the countless thousands rushing
hither and thither, the predominant suggestion was that of luxurious
ease and soft noiselessness.

Martians dislike harsh, discordant clamour. The only loud noises
they can abide are the martial sounds of war, the clash of arms,
the collision of two mighty dreadnoughts of the air. To them there
is no sweeter music than this.

At the intersection of two broad avenues Vas Kor descended from the
street level to one of the great pneumatic stations of the city.

Earthly eyes would have appeared to be conical-nosed, eight-foot
projectiles for some giant gun. In slow procession the things
moved in single file along a grooved track. A half dozen attendants
assisted passengers to enter, or directed these carriers to their
proper destination.
