Bruce's first attention was to the camels, to whom he gave that day a double feed of dora, that they might drink sufficient for the rest of their journey, should the wells in the way prove scanty of water. He then bathed in a large pool of very cold water, in a cave covered with rock, and inaccessible to the sun in any direction. All the party seemed to be greatly refreshed except the Tucorory, one of whom died about an hour after his arrival, and another early the next morning. With the corpses of his companions at his side, with dangers of every sort before him, lame and exhausted, Bruce, as usual, deliberately unpacked his instruments, to determine, notwithstanding the piercing glare of the sun and the weakness of his eyes, the longitude and latitude of Chiggre. Regularly, at noon, he had described, in a rough manner, his course through the day, carrying always a compass, with a needle of five inches radius, round his neck. His ink was fixed to his girdle, and his notes were written on very long, narrow strips of drawing paper, cut for the purpose. But subordination was now at an end, and Bruce had great difficulty in persuading his own servants to assist him in setting up his large quadrant, in order that he might determine the situation of the place. On the 17th they left Chiggre. Ismael and Georgis, the blind Greek, had complained of shivering all night, and Bruce began to be very apprehensive that some violent fever was to follow. Their perspiration had not returned since their coming out of the cold water. The day, however, was insufferably hot, and their complaints insensibly vanished. A little before eleven they were again terrified by an army of sand pillars, whose march was constantly south. At one time a number of these pillars faced to the east, and seemed to be coming directly upon them; but Bruce began now to be reconciled to this phenomenon, and the magnificence of its appearance seemed in some measure to indemnify them for the panic it had first occasioned: it was otherwise, however, with the simoom, for they all were firmly persuaded that another passage of that purple meteor would cause their deaths.
