Before Lakono, sultan of the Bari, and his favourite sultana Ischok, an ordinary-looking lady with two leathern aprons and a shaven head, came on board Selim's vessel, the Turks made repeated attempts to obtain information from some of the Sheiks concerning the gold mines, whose discovery was the main object of the expedition. A sensible sort of negro, one Lombé, replied to their questions, and extinguished their hopes. There was not even copper, he said, in the land of the Bari, although it was brought thither from a remoter country, and Lakono had several specimens of it in his treasury. On a gold bar being shown to him, he took it for copper, whence it was inferred that the two metals were blended in the specimens possessed by the sultan, and that the mountains of the copper country also yielded the more precious ore. This country, however, lay many days' journey distant from the Nile, and, had it even bordered on the river, there would have been no possibility of reaching it. At a very short distance above Palenja, the expedition encountered a bar of rocks thrown across the stream. And although Mr Werne hints the possibility of having tried the passage, the Turks were sick of the voyage and were heartily glad to turn back. At the period of the floods the river rises eighteen feet; and there then could be no difficulty in surmounting the barrier. Now the waters were falling fast. The six weeks lost by Arnaud's fault were again bitterly deplored by the adventurous German--the only one of the party who really desired to proceed. Twenty days sooner, and the rocks could neither have hindered an advance nor afforded pretext for a retreat. To Mr Werne's proposal, that they should wait two months where they were, when the setting in of the rains would obviate the difficulty, a deaf ear was turned--an insufficient stock of provisions was objected; and although the flotilla had been stored for a ten months' voyage, and had then been little more than two months absent from Chartum, the wastefulness that had prevailed gave some validity to the objection. One-and-twenty guns were fired, as a farewell salute to the beautiful country Mr Werne would so gladly have explored, and which, he is fully convinced, contains so much of interest; and the sluggish Egyptian barks retraced their course down stream. It is proper here to note a shrewd conjecture of Mr Werne's, that above the point reached by himself and his companions, the difficulties of ascending the river would greatly and rapidly increase. The bed becomes rocky, and the Bach'r el Abiat, assuming in some measure the character of a mountain stream, augments the rapidity of its current: so much so, that Mr Werne insists on the necessity of a strong north wind, believing that towing, however willingly and vigorously attempted, would be found unavailing. This is another strong argument in favour of employing steamboats.
