The hurricane, at last, after having exhausted its impotent fury against the soldiers of Allah, passed away to ravage other regions and the Faithful had no further accidents to deplore. But they were broken down by their former difficult marches; and that night, instead of granting invigorating rest, only brought them fresh fatigue. The simoon having dried up the last vestiges of moisture in their bodies, their thickened blood circulated difficultly in their veins and the beatings of their temples led to unbearable singing in the ears. What would become of them on the long road they still had to travel before reaching the first well? The aspect of the surrounding country was not at all calculated to encourage them. They fancied that they were tramping through the ruins of a world destroyed by an inconceivable outbreak of fire. A black line marked the horizon: the never-ending Harra, which seemed in some parts to be formed of coal, soot and ashes; and in others, of iron congealed when molten, with enormous bubbles which, in bursting, had laid great crevices open, bordered with scattered slag as sharp as broken glass.... There, at any rate, the flames were extinguished, whereas, on the way they went, fires seemed to be still smouldering. Blocks of rock rose up on all sides, like a real forest, and by their shape and colour, they could bear comparison with gigantic tree-trunks, partly calcined and partly incandescent. Some were distorted in such strange fashion that, in the eyes of the Faithful, they looked like mouthing demons escaped from Hell and posted where they stood to revel in the torments of Allah's soldiers passing by. Slippery slabs and pointed black stones of volcanic origin covered the earth, except where it was carpeted by sand of dazzling whiteness which, by its intense reverberation, kindled myriads of white-hot embers under every stone and in all the windings and turnings of the crags and peaks. Even in the depths of the sapphire sky, a hovering vulture and a rare fleeting cloud were tinted with a bright orange hue, as if they reflected the blaze of an immense furnace. To complete the illusion, lofty pillars of sand hung over all these remains, like columns of smoke issuing from a badly-extinguished conflagration. The Believers' eyes, inflamed by the sandstorm, reddened by the refraction on the dunes, produced--even in their sockets--the effect of burning embers. Each time they put their feet, lacerated by the pebbles of the Hammada, to the overheated ground, their sufferings were unbearable. Their thickened saliva, mixed with impalpable dust, formed a firm paste, which the throat would not allow to pass. Their skin, stretched as on a drumhead, resounded at the slightest touch, cracking in broad furrows, and split lips made speech impossible.
