It was shocking to the ladies to look at their companion and to think of the spruce, hale old soldier who had been their fellow-passenger from Cairo. As in the case of Miss Adams, old age seemed to have pounced upon him in one spring. His hair, which had grizzled hour by hour during his privations, was now of a silvery white. White stubble, too, had obscured the firm, clean line of his chin and throat. The veins of his face were injected and his features were shot with heavy wrinkles. He rode with his back arched and his chin sunk upon his breast, for the old, time-rotted body was worn out, but in his bright, alert eyes there was always a trace of the gallant tenant who lived in the shattered house. Delirious, spent, and dying, he preserved his chivalrous, protecting air as he turned to the ladies, shot little scraps of advice and encouragement at them, and peered back continually for the help which never came.
An hour after sunrise the raiders called a halt, and food and water were served out to all. Then at a more moderate pace they pursued their southern journey, their long, straggling line trailing out over a quarter of a mile of desert. From their more careless bearing and the way in which they chatted as they rode, it was clear that they thought that they had shaken off their pursuers. Their direction now was east as well as south, and it was evidently their intention after this long detour to strike the Nile again at some point far above the Egyptian outposts. Already the character of the scenery was changing, and they were losing the long levels of the pebbly desert, and coming once more upon those fantastic, sunburned black rocks and that rich orange sand through which they had already passed. On every side of them rose the scaly, conical hills with their loose, slaglike _débris_, and jagged-edged khors, with sinuous streams of sand running like watercourses down their centre. The camels followed each other, twisting in and out among the boulders, and scrambling with their adhesive, spongy feet over places which would have been impossible for horses. Among the broken rocks those behind could sometimes only see the long, undulating, darting necks of the creatures in front, as if it were some nightmare procession of serpents. Indeed, it had much the effect of a dream upon the prisoners, for there was no sound, save the soft, dull padding and shuffling of the feet. The strange, wild frieze moved slowly and silently onwards amid a setting of black stone and yellow sand, with the one arch of vivid blue spanning the rugged edges of the ravine.
