as
often as their pleasure.

When the dromedary lifted itself out of the last break of the wady,
the traveller had passed the boundary of El Belka, the ancient
Ammon. It was morning-time. Before him was the sun, half curtained
in fleecy mist; before him also spread the desert; not the realm
of drifting sands, which was farther on, but the region where the
herbage began to dwarf; where the surface is strewn with boulders
of granite, and gray and brown stones, interspersed with languishing
acacias and tufts of camel-grass. The oak, bramble, and arbutus
lay behind, as if they had come to a line, looked over into the
well-less waste and crouched with fear.

And now there was an end of path or road. More than ever the camel
seemed insensibly driven; it lengthened and quickened its pace, its
head pointed straight towards the horizon; through the wide nostrils
it drank the wind in great draughts. The litter swayed, and rose
and fell like a boat in the waves. Dried leaves in occasional beds
rustled underfoot. Sometimes a perfume like absinthe sweetened all
the air. Lark and chat and rock-swallow leaped to wing, and white
partridges ran whistling and clucking out of the way. More rarely
a fox or a hyena quickened his gallop, to study the intruders at
a safe distance. Off to the right rose the hills of the Jebel,
the pearl-gray veil resting upon them changing momentarily into
a purple which the sun would make matchless a little later.
Over their highest peaks a vulture sailed on broad wings into
widening circles. But of all these things the tenant under the
green tent saw nothing, or, at least, made no sign of recognition.
His eyes were fixed and dreamy. The going of the man, like that of
the animal, was as one being led.

For two hours the dromedary swung forward, keeping the trot
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
