"We continued for some distance up the stream with the same unfortunate results. The banks, although flooded during the wet season, were now dry, and a forest was about a mile distant. Having left the boat and ascended a white ant-hill, about eight feet high, in order to take a view of the country, I observed a herd of very beautiful antelopes, of a kind that were quite un known to me. "By careful stalking on the flat plain from one ant-hill to another, I obtained a fair shot at about 140 yards, and killed. Both male and female have horns, therefore I found it difficult to distinguish the sex at that distance. I was delighted with my prize; it was a female, weighing, I should estimate, about twenty stone, clean. The hide was a deep reddish yellow, with black shoulders and legs, also black from the hind quarters down the hind legs. It belonged to the species hippotragus, and had horns that curved backwards, something similar to the hippotragus niger, but much shorter.[*] [*Footnote: Vide Appendix. This antelope, which I considered to be a new species, proved to be the Damalis Senegalensis of Western Africa.] "We soon cut it into quarters, and carried it to the boat. This little success in sport had cheered me for the moment; but the happy excitement quickly passed away, and we returned to the diahbeeah quite disheartened. It is simply impossible to continue the voyage, as there is no means of floating the vessels. "To-morrow I shall explore the channel No. 3, which runs from the W.S.W. "April 2.--I explored the west channel. This is very narrow, and overgrown with grass. After about a mile we arrived at a shallow place only two feet deep. The whole river is absolutely impracticable at this season. During the rains, and even to the end of December, when the river is full, the vessels could pass, but at no other time. All my labour has been useless, but it would be utterly absurd to attempt a further advance. I have therefore determined to return at once to the Shillook country, and establish a station. Mr. Higginbotham and party will then unite with us, and I will collect the entire force from Khartoum, and start with the expedition complete in the end of November. Although I am grievously disappointed, I am convinced that this is the wisest course. During the rainy season the troops shall cultivate corn, and I shall explore the old White Nile in a steamer, and endeavour to discover a navigable channel via the original route by the Bahr Gazal. "I was obliged with a heavy heart to give the sad order to turn back; at 3 p.m. we arrived at the assembled fleet.
