On the sandy shore, on the west side of the Nile, are numberless beetles (Scarabæi), of great variety in size and shape; I often found the sandy road on that side completely covered with the traces of their feet. The Nubians, who call them Kafers, or Infidels, dread them from a belief that they are venomous, and that they poison whatever kind of food they touch. Their colour is generally black, and the largest I have seen were of the size of a half-crown piece. The worship paid to this animal by the ancient Egyptians may probably have had its origin in Nubia; it might well be adopted as a symbol of passive resignation to the decrees of providence; for it is impossible, from the sandy mounds which they inhabit, that these beetles can ever taste water, and the food they partake of must be very scanty; they are however always seen busily and unweariedly toiling their way over the sands. The Nubians have no fishing apparatus whatever, except at the first Cataract, at Derr, and at the second Cataract, where some fish are occasionally caught in nets. The two species of fish which seem to be most common, are called by the natives Dabesk and Meslog. The country which I had crossed, from Assouan to Derr, is divided by its inhabitants into two parts: the Wady el Kenous, which extends from Assouan to Seboua, and the Wady Nouba, comprising the whole country south of Seboua, as far as the northern limits of Dongola. Of the Wady Nouba, and its inhabitants, I shall speak hereafter.[20] The Wady el Kenous is inhabited by the Arabs Kenous (sing. Kensy, قنسي), who derive their origin, according to their own tradition, from the deserts of Nedjed, and who settled here at the period when the great Bedouin tribes from the East spread over Egypt.[21] Among these were also Bedouins of the neighbourhood of Bagdad, whose descendants are still known by the name of Bagdadli, and inhabit the Wady Dehmyt, and Wady el Embarakat, on the western side of the river. The Kenous are subdivided into many smaller tribes, which have given their names to the districts they inhabit; thus, Wady Nasrellab, Abou Hor, &c. &c., are inhabited by Kenous of the tribe of Nasrellab, and Abou Hor. Great jealousies often exist amongst these different tribes, which sometimes break out in wars.
