The slave caravan from Mahass, which I mentioned above, passed along the west bank of the river, while I was at Eshke; the usual route of these caravans, which generally visit Egypt twice in the year, lies across the desert, from Mahass to the Great Oasis, a journey of twenty-three days; and from thence to Siout and Cairo. It was only this year that the slave-traders, informed of the perfectly tranquil state of Nubia and Upper Egypt, had ventured to proceed along the banks of the Nile, a road they had not followed in the memory of man. To the south of Eshke is a sandy plain; in three hours, we reached Dabrous (دَبروس); the direction of the road S. W. by S. Four hours, Sukoy (سَقوي). Five hours, Wady Halfa (وادي حلفه), to the east of which, the eastern mountain terminates in slight undulations of the ground; but these increase in size, and collect again into mountains, about thirty miles farther up. There is some trade carried on at Wady Halfa; vessels from Assouan often moor here to load dates, and the nitre which the Arabs collect at three days journeys from hence in the western desert.[29] In summer, the navigation from Derr to Wady Halfa becomes, in many places, very difficult, except for small boats, on account of the sand banks. One of the relations of the governors of Nubia resides here, and collects the revenue. At the end of six hours, we came to the southern extremity of Wady Halfa. The river forms here several islands, upon one of which are the remains of an ancient town, built of bricks, with a high brick wall. Seven hours, the plain over which we rode became uneven, and studded with insulated clusters of rocks, whose summits just appear above the surface of the sand. To the west is the second Cataract. Eight hours, halted for the night, in this desert, near one of the islands, which are formed by the river. The noise of the Cataract was heard in the night, at about half an hour’s distance. The place is very romantic; when the inundation subsides, many small lakes are left among the rocks; and the banks of these, overgrown with large tamarisks, have a picturesque appearance amidst the black and green rocks; the lakes and pools thus formed cover a space of upwards of two miles in breadth. I here shot a wild-goose, which afforded a supper to our party, now increased by the company of a poor young girl from Dabrous, who ran after us, when she saw us pass by, and begged we would take her under our protection as far as Wady Mershed, beyond the Cataract. From Wady Halfa to Sukkot is a stony wilderness, with many cataracts in the river, similar to that at Assouan; and the navigation is interrupted for about one hundred miles. This rocky tract is called Dar el Hadjar, or Batn el Hadjar, i. e. the rocky district, or the “womb of rocks.”
