We went gently up the knoll of graves over the great pools, and saw that the watering places were empty. A mirage hung over the open spaces: but here, where the ground was bushed, no heatwaves could collect, and the strong sunlight showed us the valley as crystal clear as its running waters, and deserted except by wild birds, and these herds of gazelles, which, alarmed by the popple of our closed exhausts, were grouping timidly in preparation for flight.

Rolls drew his tender past the Roman fishpond; we skirted the western lava-field, along the now hard, grass-grown swamp, to the blue walls of the silent fort, with its silken-sounding palms, behind whose stillness lay perhaps more fear than peace. I felt guilty at introducing the throbbing car, and its trim crew of khaki-clad northerners, into the remoteness of this most hidden legendary place: but my anticipation went astray, for it was the men who looked real and the background which became scene-painting. Their newness and certainty (the Definiteness of British troops in uniform) did Azrak greater honour than plain loneliness.
