Burckhardt arrived at Derr on the 1st of March, and, to his surprise, found two Mameluke beys at the palace of the governor. He had reckoned upon their utter disappearance, and had intended, under these circumstances, to represent himself as the secret agent of the Pasha of Egypt; but learning, upon inquiry, that the pasha and his enemies were regarded with nearly equal dread by the Nubian princes, he changed his resolution, and professed to be guided in his motions by no other motive than pleasure. Ignorant persons find it hard to conceive that men can expose themselves to difficulties and dangers from an enthusiasm for knowledge, or can find pleasure in encountering hardships and fatigue; however, a concurrence of fortunate circumstances extorted from the governor a permission to proceed, and accordingly, having provided himself with provisions for the road, our traveller departed for Sukkot. His guide on the present occasion was an old Arab of the Ababde tribe. The branch of the Ababde to which this man, whose name was Mohammed, belonged, feed their flocks on the uninhabited banks of the river, and on its numerous islands, as far south as Dongola. Though poor, they refuse to bestow their daughters, who are famed for their beauty, in marriage on the rich Nubians, and have thus preserved the purity of their race. They are, moreover, an honest and hospitable race, and during his journeys in Nubia, Burckhardt was constantly received and treated with kindness by these simple people. In pursuing his course up the Nile, our traveller passed a day at Ibrim, a town inhabited by Turks, where, though quarrels and bloodshed were frequent, property was more secure than in any other town he had visited in the eastern world; the corn was left all night in the field, and the cattle on the banks of the river, unwatched, and even the greater part of the household furniture remained all night under the palm-trees around their dwellings. Indeed, theft was here quite unknown. Proceeding a short distance to the south of this town, he dismounted from his dromedary, and directing his guide to continue his road to the next village, struck off into a narrow footpath along the lofty, precipitous shores of the river. Pursuing this mountain-track he arrived at an ancient temple hewn out of the rock, in as perfect a state of preservation as when first finished. Sepulchral chambers and mystic sculptures, the usual accompaniments of Egyptian temples, were found here.
