I felt that I was quite justified in talking in this fashion to a people who, under the cloak of religion, are as unscrupulous rascals as any in the world, and who, misinterpreting the mottoes on their banners which incite them to war against the infidel, consider all plunder perpetrated on defenceless savages as heroic actions bearing them onwards to the palms of Paradise. The chief Seriba of this eastern section of Ghattas’s establishments lies only a league and a half to the north-east of Dimindoh, and was called Dangadduloo, after a certain Danga, who had been appointed the head of the Mittoo of the district. In 1863 the brothers Poncet of Khartoom had ceded to Ghattas their settlements amongst the Agar, on the Rohl, in order to found fresh establishments in the following year near the cataracts of that river, among the Lehssy. The Agar, as I have already mentioned, had managed to obtain possession of a considerable quantity of firearms and ammunition, and had made themselves so formidable that the Khartoomers had not ventured to rebuild the Seriba that had been destroyed: for that reason, the settlements of Ghattas had receded southwards to the region in which I now found myself. Our road lay often across wide gneiss flats, which not unfrequently exhibited the same uniformity for several hundred yards together. From the surface the stone broke off in smooth laminæ, often as thin as the cover of a book, and afforded me a convenient material for pressing my packets of plants. We had crossed the Wohko for the second time at Dimindoh, where its bed was about fifteen feet deep: its course is generally due north, but here it bends at a right angle to the east, as if seeking the shortest route to join the Rohl. The little river abounds in shells, especially in Anodontæ, which are turned to many domestic uses by the natives, while the massive _Etheria Cailliaudii_, not unlike the oyster, forms continuous banks in all these minor streams.
