Mohammed Ali, being dissatisfied with the result of this expedition, appointed in the very same year a second voyage of discovery. Various motives have been alleged for this glorious resolution. He either wished, with respect to various ulterior views, to have a country inspected, which had pleased him so well in his journey to Fàzogl, because, among other advantages, it contains the radius of the circle of an immeasurable kingdom, whose motto is “_Noli me tangere_;” or he thought of opening another commercial road in the interior of Africa. Perhaps his restless and avaricious heart hoped to find a real golden fleece, with the acquisition of which—like Nero, who also ordered the sources of the Nile to be sought for—he might connect the reputation of a lover of science. Nevertheless, he has, like a true Renard the Fox, scented out his _Malepartus_,[1] even if he have not gone as a penitent pilgrim to Turkish Rome. There the report was spread, and believed, that the old Basha would return to Sennaar. Even Ahmed Basha, the Governor-General of the land of Sudàn, and the greatest Verres among the Bashas of Mohammed Ali, feared such an unwelcome visit in Sennaar, after the taking of St. Jean d’Acre; and the merchants of the place wished it, because money, by that means, would flow into the country. This Ahmed Basha had also other reasons, which I will detail afterwards, for fearing such a change of residence. Nevertheless, whatever may have been the secret thoughts of Mohammed Ali, a second expedition was resolved upon in 1840, and this time I was fortunate enough to take a part in it myself. For seven months I had been present in the Taka country, in a district previously untrodden by Europeans, at a campaign opened by Ahmed Basha, against the _free_ people of that district, who are called, as being such, _Asi_. That _nomen_ is one of the words of the diplomatic language of the day, not sufficiently expressive, because it means _rebels_ as well as _free men_, and reminds us besides of Asia and the godlike Asi of the North. For a long time we had our camp surrounded with palisadoes of thick palm-trees, under the wonderful granite rocks of Kaffela-el-Lus, rising up above us like a dome, to the height of more than 3.000 feet, near the village of Kadmir, in the country of the Hallengas, when orders arrived from Káhira for the second expedition. The Basha permitted me at last to accompany this highly interesting enterprise; but my brother, who was his physician in ordinary, could not share in this favour, on account of the great mortality in the camp. For three days we considered and wavered, before we resolved upon the journey, and then we mutually promised not to be always forward in exposing ourselves to danger: for separation is no trifling matter in these countries, where, from the frequent diseases, and other misfortunes, no compassion is to be expected; where neither friendship nor love, and still less gratitude, is known.
