She continued to lead us on in this wanton manner, until we were aware that we had wandered from the road further than was prudent. At last, she ran towards some narrow defiles; but we did not allow our ardour for the chase to carry us further. Although conscious we were in the direction the caravan must take, we did not see it for some time, and felt a strange inquietude on finding ourselves alone, destitute, and helpless, in the midst of this immense desert. I fired my gun, and, the signal being answered, our uneasiness was relieved. Towards the end of this chain of hills, about two hours’ journey east of the direct road, is a place called Absah, where there are traces of gold mines, and, as at the one at the same distance from the valley of the dooms, numerous remains of habitations, but apparently not very ancient. The stones with which they were worked remain, and there are wells now dry. The Arabs keep them a great secret, and will take no traveller to visit them, unless he has a particular order from the Pasha, and is protected by one of their chiefs. M. Bonomi, who enjoyed these advantages, will, I hope, soon give us an account of them. The result, I believe, of his investigation was, that they are now so exhausted, that they would not repay the labour of working. At eleven we entered a large sandy plain, and at four P.M. we passed some hills of a pyramidal shape. They are of syenite, and their formation is similar to the round granite rocks of the First Cataract. They are called El Talati Greibat—the Three Greibat—from their being at a distance apparently only three. They extend considerably towards the east; but some of them are so low as to be nearly covered with the sand. North-east of these I observed some hills of the same conical form, called Adaramat; but I was at too great a distance from them to perceive whether they were of granite. After eleven hours’ ride, we encamped in the plain at six. The wind is very high; I am almost afraid of my tent being carried away. For several days I have been on the look out, thinking it possible that on these light sandy plains I might see some of Bruce’s pillars of moving sand; but I have not been favoured with the view of any such _stalking_ prodigy; and I must declare that, notwithstanding the numerous deserts I have crossed, at different seasons, always making particular enquiries on the subject, I have neither seen nor heard of such as he describes. The wandering Arabs tell the women, children, and peasants of the Nile fearful stories of the whirlpool of the desert, and the terrible simoom; but such tales, embellished by an Oriental imagination, will rarely bear investigation. From what I have been able to ascertain, there are certain gusts of wind which occasionally sweep over these deserts, with clouds of sand, which prevent your distinguishing any object at all distant; but these are not very dangerous to caravans, except in those tracts where there
