steadily and the line due east. In that time the traveller never
changed his position, nor looked to the right or left. On the
desert, distance is not measured by miles or leagues, but by the
saat, or hour, and the manzil, or halt: three and a half leagues
fill the former, fifteen or twenty-five the latter; but they are
the rates for the common camel. A carrier of the genuine Syrian
stock can make three leagues easily. At full speed he overtakes
the ordinary winds. As one of the results of the rapid advance,
the face of the landscape underwent a change. The Jebel stretched
along the western horizon, like a pale-blue ribbon. A tell, or hummock
of clay and cemented sand, arose here and there. Now and then basaltic
stones lifted their round crowns, outposts of the mountain against the
forces of the plain; all else, however, was sand, sometimes smooth as
the beaten beach, then heaped in rolling ridges; here chopped waves,
there long swells. So, too, the condition of the atmosphere changed.
The sun, high risen, had drunk his fill of dew and mist, and warmed
the breeze that kissed the wanderer under the awning; far and near
he was tinting the earth with faint milk-whiteness, and shimmering
all the sky.

Two hours more passed without rest or deviation from the course.
Vegetation entirely ceased. The sand, so crusted on the surface
that it broke into rattling flakes at every step, held undisputed
sway. The Jebel was out of view, and there was no landmark visible.
The shadow that before followed had now shifted to the north, and was
keeping even race with the objects which cast it; and as there was
no sign of halting, the conduct of the traveller became each moment
more strange.

No one, be it remembered, seeks the desert for a pleasure-ground.
