On the 15th, the same moving pillars of sand presented themselves, only they seemed to be more in number and less in size. They came several times in a direction close upon them. "They began," says Bruce, "immediately after sunrise, like a thick wood, and almost darkened the sun. His rays shining through them for near an hour, gave them an appearance of pillars of fire. Our people now became desperate; the Greeks shrieked out, and said it was the day of judgment. Ismael pronounced it to be hell; and the Tucorories, that the world was on fire. I asked Idris if ever he had before seen such a sight; he said he had often seen them as terrible, though never worse; but what he feared most was that extreme redness in the air, which was a sure presage of the coming of the simoom. I begged and entreated Idris that he would not say one word of that in the hearing of the people, for they had already felt it at Imhanzara, in their way from Ras el Feel to Teawa, and again at the Acaba of Gerri, before we came to Chendi, and they were already nearly distracted at the apprehension of finding it here."

At half past four o'clock in the afternoon they left Waadi Dell Aned. The sands scarcely showed themselves this day, and only at a great distance in the horizon. This was, however, a comfort but of short duration. Bruce observed that Idris took no notice of it, but warned him and the servants that, upon the coming of the simoom, they should fall on their faces, with their mouths upon the earth, so as not to inhale the outward air as long as they could hold their breath. They alighted at six o'clock at a small rock called Ras el Seah, or El Mout, which signifies death. It is surrounded with sand, is without trees or herbage, and the poor camels fasted all that night.

On the 16th, at half past ten in the forenoon, they left El Mout. "Our men," says Bruce, "if not gay, were, however, in better spirits than I had seen them since we left Goos. One of our Barbarins had even attempted a song; but Hagi Ismael very gravely reproved him, by telling him that singing in such a situation was a tempting of Providence. There is, indeed, nothing more different than active and passive courage. Hagi Ismael would fight, but he had not strength of mind to suffer. At eleven o'clock, while we contemplated with great pleasure the rugged top of Chiggre, to which we were fast approaching, and where we were to solace ourselves with plenty of good water, Idris cried out, with a loud voice, 'Fall upon your faces, for here is the simoom!' I saw from the southeast a haze come, in colour like the purple part of the rainbow, but not so compressed or thick. It did not occupy twenty yards in breadth, and was about twelve feet high from the ground. It was a kind of blush upon the air, and it moved very rapidly, for I scarce could turn to fall upon the ground, with my head to the northward, when I felt the heat of its current plainly upon my face. We all lay flat on the ground, as if dead, till Idris told us it was blown over. The meteor or purple haze which I saw was indeed passed, but the light air that still blew was of a heat to threaten suffocation. For my part, I found distinctly in my breast that I had imbibed a part of it, nor was I free of an asthmatic sensation till I had been some months in Italy at the baths of Poretta, near two years afterward.[36]

"A universal despondency had taken possession of our people. They ceased to speak to one another, and when they did it was in whispers, by which I easily guessed their discourse was not favourable to me, or else that they were increasing each other's fears by vain suggestions calculated to sink each other's spirits still farther, but from which no earthly good could possibly result. I called them together, and both reprimanded and exhorted them in the strongest manner I could. I bade them attend to me, who had nearly lost my voice by the simoom, and desired them to look at my face, so swelled as scarcely to permit me to see, my neck covered with blisters, my feet swelled and inflamed, and bleeding with many wounds. In answer to the lamentation that the water was exhausted, and that we were upon the point of dying with thirst, I ordered each man a gourd full of water more than he had the preceding day, and showed them, at no great distance, the bare, black, and sharp point of the rock Chiggre, wherein was the well at which we were again to fill our girbas, and thereby banish the fear of dying by thirst in the desert. I believe I never was at any time more eloquent, and never had eloquence a more sudden effect. They all protested and declared their concern chiefly arose from the situation they saw me in; that they feared not death or hardship, provided I would submit to their direction in taking proper care of myself. They entreated me to use one of the camels, and throw off the load that it carried, that it might ease me of the wounds in my feet, by riding at least part of the day. This I positively refused to do, but recommended to them to be strong of heart, and to spare the camels for the last resort, if any should be taken ill and unable to walk any longer.

"This phenomenon of the simoom, unexpected by us, though foreseen by Idris, caused us all to relapse into our former despondency. It still continued to blow, so as to exhaust us entirely, though the blast was so weak as scarcely would have raised a leaf from the ground. At twenty minutes before five the simoom ceased, and a comfortable and cooling breeze came by starts from the north, blowing five or six minutes at a time, and then falling calm. We were now come to the Acaba, the ascent before we arrived at Chiggre, where we intended to have stopped that night; but we all moved on with tacit consent, nor did one person pretend to say how far he guessed we were to go." At thirteen minutes past eight they alighted in a sandy, barren plain, covered with loose stones. They were now only a quarter of a mile due north from the well, which is in the narrow gorge forming the southern outlet of this small plain. Though they had travelled thirteen hours and a quarter this day, it was but a slow pace, the wretched camels being famished as well as tired, and lamed by the sharp stones with which the ground in all places was covered. The country, for three days past, had been destitute of herbage of any kind, entirely desert, and abandoned to moving sands; which might be said to "sweep it with the besom of destruction."

Chiggre is a small narrow valley, about half way across the great desert of Nubia, and surrounded with barren rocks. The wells are ten in number, and the narrow gorge by which they are approached is not ten yards broad. The springs, however, are very abundant. Wherever a pit is dug five or six feet deep, it is immediately filled with water. The principal pool is about forty yards square and five feet deep; but the best-tasted water was in the cleft of a rock, about thirty yards higher, on the west side of this narrow outlet.

The eagerness with which Bruce and his party rushed to these wells can scarcely be imagined; for no one would believe the effect which the sight of water under such circumstances produces on the human frame, unless he had himself experienced the burning thirst of the desert.

The springs were exceedingly foul, having been visited by animals of many descriptions. It was impossible to drink without putting a piece of a cotton girdle over the mouth, to keep out, by filtration, the filth of the putrid substances with which they were filled. Bruce saw a number of partridges on the face of the bare rock, but he did not dare shoot at them, for fear of being heard by wandering Arabs that might be in the neighbourhood; for Chiggre is a haunt of the Bishareen of the tribe of Abou Bertran, who, though they do not make it a station, because there is no pasture, nor can anything grow there, yet find it one of their most valuable places of refreshment, on account of the great quantity of water.
