On his arrival at Cairo, Burckhardt’s first employment was to draw up a detailed account of his journey through Arabia Petræa: he then turned his attention to the means of fulfilling the great design of his mission; but no opportunity of penetrating into the interior of Africa occurring, he undertook, in order to fill up the interval thus created, a journey into Nubia. During his residence at Cairo, and on his journey up the Nile to Assouan, he beheld the principal ruins of Egypt. His preparations for the Nubian excursion were soon made. He purchased two dromedaries, one for himself and the other for his guide, for about twenty-two pounds; provided himself with letters of recommendation, and a firman from the pasha; and leaving his servant and baggage at Assouan, set out with his guide on the 14th of February, 1813, carrying along with him nothing but a gun, a sabre, a pistol, a provision-bag, and a woollen mantle, which served by day for a carpet, and for a covering during the night. Their road lay along the eastern bank of the Nile; they passed Philæ (where, a few days before, a pregnant woman had been killed in a fray, as the softer sex always mix in the battles in which their husbands are engaged, which had created a deadly feud between the hostile villages); and then pushed on with rapidity towards Derr. The Mameluke chiefs, with their desperate followers, were at this period roaming about Nubia, amusing their imaginations with vain projects for the recovery of Egypt.--Every person coming from the north was of course an object of curiosity, if not of suspicion, to these baffled soldiers, as it was possible he might be the bearer of tidings of events upon the results of which their fate depended. Such was the state of things when Burckhardt entered Nubia. Everywhere reports calculated to create alarm were circulated. To-day it was said that the Mamelukes had descended, like famished tigers, from the mountains, and were about to deliver up the whole country to plunder and devastation; to-morrow they appeared to have passed away, like a thunder-cloud, towards Dongola and the desert, leaving behind them that sort of uneasy satisfaction with which we behold the quelling of unruly elements.
