rocky desert, where the eye, fatigued by the view of the dreary wilderness, searches with difficulty for the blue stream, often hidden by islands, and only appearing partially. Its course from hence is S. W. by S. At seven hours, we descended from the mountain into Wady Ambigo (اَمبقُو). At eight hours, were several cataracts, where the stream rushes impetuously over the rocks, and carries its foaming current to the distance of several hundred feet; there is no where, however, any fall, that can be properly so called. All these cataracts resemble those of Assouan, but the river is more narrowly hemmed in by rocks than at the latter place; and its whole course through the Batn el Hadjar is so very rapid, that navigation of every kind seems to be quite impracticable. At the end of nine hours, we stopped at a hut of Omsherifs. _March 9th._ To the east of Ambigo, there are high mountains; and to the south of it, the eastern chain decreases in height. The mountains of Ambigo seem to be the highest summit of the Batn el Hadjar. Our road lay alternately along the shore, and over the rocks; I no where saw any traces of an ancient road through this rugged district. In three hours we reached Wady Om Kanaszer (اُم قناَصِر), in which is a small watch-tower built of stones, upon a hill. From hence we followed a mountainous road as far as Wady Lamoule (وادي لاموله), which we reached in five hours; here are some cataracts in the river, and several rocky islands, upon which I saw crocodiles basking. At five hours and a half, we ascended the mountain; and in six hours gained a high summit, known by the name of Djebel Lamoule (جبل لامولَه), and corresponding with a similar one on the west side. At the foot of this hill, the Arabs repeat the custom of digging the traveller’s grave, but as I knew not how often a present might in this way be demanded of me by my guide, I refused to give him any thing upon his making the demand; and as soon as he began to construct my tomb, I alighted, and making another, told him that it was intended for his own sepulture; for that, as we were brethren, it was but just that we should be buried together. At this, he began to laugh; we then mutually destroyed each other’s labours, and in riding along he exclaimed from the Coran, “No mortal knows the spot upon earth where his grave shall be digged.” Seven hours brought us to a sandy plain in the mountain, called Khor Sonk (خور سُنك), Sonk being a Wady, situated below it. As the road which leads to the country of the Sheygya turns off here, this spot is more frequently visited by them, than any other part of this rocky tract, and is noted for the many robberies committed here by those Arabs; my guide shewed me the place where his cousin had been killed, at his side, in an encounter with the Sheygya, and hurried me, at a full trot, over the plain. The whole of the Batn el Hadjar is dangerous for single travellers; but it was my good fortune not to meet with any banditti;
