"The usual Egyptian delays have entirely thwarted my plans. No vessels have arrived from Cairo, as they only started on 29th August. Thus, rather than turn back, I start with a mutilated expedition, without a SINGLE TRANSPORT ANIMAL."
Having minutely described the White Nile in a former work, "The Albert N'yanza," I shall not repeat the description. In 103 hours and ten minutes' steaming we reached Fashoda, the government station in the Shillook country, N. lat. 9 degrees 52 minutes, 618 miles by river from Khartoum.
This town had been fortified by a wall and flanking towers since I had last visited the White Nile, and it was garrisoned by a regiment of Egyptian soldiers. Ali Bey, the governor, was a remarkably handsome old man, a Kurd. He assured me that the Shillook country was in excellent order; and that according to the instructions received from the Khedive he had exerted himself against the slave trade, so that it was impossible for vessels to pass the station.
Fashoda was well situated for this purpose, as it completely dominated the river; but I much doubted my friend's veracity.
Having taken on board a month's rations for all hands, we started; and, with a strong breeze in our favour, we reached the Sobat junction on 16th February, at 12.30 p.m.
There we took in fresh water, as that of the Sobat is superior to the White Nile. At this season the river was about eight feet below the level of the bank. The water of the Sobat is yellowish, and it colours that of the White Nile for a great distance. By dead reckoning I made the Sobat junction 684 miles by river from Khartoum.
When I saw the Sobat, in the first week of January 1863, it was bank-full. The current is very powerful, and when I sounded in various places during my former voyage, I found a depth of twenty-six to twenty-eight feet. The volume of water brought to the Nile by this river is immense, and the power of the stream is so superior to that of the White Nile, that as it arrives at right angles, the waters of the Nile are banked up. The yellow water of the Sobat forms a distinct line as it cuts through the clear water of the main river, and the floating rafts of vegetation brought down by the White Nile, instead of continuing their voyage, are headed back, and remain helplessly in the backwater. The sources of the Sobat are still a mystery; but there can be no doubt that the principal volume must be water of mountain origin, as it is coloured by earthy matter, and is quite unlike the marsh water of the White Nile. The expeditions of the slave-hunters have ascended the river as far as it is navigable. At that point seven different streams converge into one channel, which forms the great river Sobat. It is my opinion that some of these streams are torrents from the Galla country, while others are the continuation of those southern rivers which have lately been crossed by the slave-hunters between the second and third degrees of N. latitude.
The White Nile is a grand river between the Sobat junction and Khartoum, and after passing to the south of the great affluent the difference in the character is quickly perceived. We now enter upon the region of immense flats and boundless marshes, through which the river winds in a labyrinth-like course for about 750 miles to Gondokoro.
Having left the Sobat, we arrived at the junction of the Bahr Giraffe, thirty-eight miles distant, at 11 a.m. on 17th February. We turned into the river, and waited for the arrival of the fleet.
The Bahr Giraffe was to be our new passage instead of the original White Nile. That river, which had become so curiously obstructed by masses of vegetation that had formed a solid dam, already described by me in "The Albert N'yanza," had been entirely neglected by the Egyptian authorities. In consequence of this neglect an extraordinary change had taken place. The immense number of floating islands which are constantly passing down the stream of the White Nile had no exit, thus they were sucked under the original obstruction by the force of the stream, which passed through some mysterious channel, until the subterranean passage became choked with a wondrous accumulation of vegetable matter. The entire river became a marsh, beneath which, by the great pressure of water, the stream oozed through innumerable small channels. In fact, the White Nile had disappeared. A vessel arriving from Khartoum in her passage to Gondokoro would find, after passing through a broad river of clear water, that her bow would suddenly strike against a bank of solid compressed vegetation—this was the natural dam that had been formed to an unknown extent: the river ceased to exist.
