We marched south for sixteen miles through a fine country of hills and low forest, where the villages of the Madi had been mostly destroyed by the slave-hunting parties of Abou Saood. We passed large tracts of land that had formerly been in a high state of cultivation, and the charred remains of numerous villages bespoke the desolation caused by these brigands of the White Nile. The road was well watered by many small streams in deep gorges, until we descended to the Asua river. This was just twenty-five miles from our camp at Lobore, in latitude N., by observation, 3 degrees 43 minutes. We happened to arrive at the spot where the river Atabbi joined the Asua. At this junction the Atabbi was perfectly clear, while the Asua was muddy, which proved that heavy rain had fallen in the Madi and Shooli countries, while the weather was dry in the mountains of Obbo. The Asua flowed through a fine forest, but although the water was muddy from recent rains, the volume at this season was confined to a portion of the bed, in the deepest parts of which it did not exceed two feet six inches. The bed from bank to bank was about 120 yards in width, and the maximum rise of the river was about twelve feet. During the wet season this is a frightful torrent that acts as a barrier to any advance or retreat of troops encumbered with baggage. Having waded through the river, we halted under the shady trees on the south side; here there was excellent herbage for the cattle, as the young grass after the annual fires was now about eight inches high, upon the rich soil near the river's bank. Whenever we halted during daylight, I took a stroll with the rifle, accompanied by Lieutenant Baker. We walked for some time along the banks of the river up stream without seeing any game, and I was struck with the absence of tracks of the larger animals, which coincided with my remarks on the Asua river many years previous, when I crossed it about thirty miles higher up, on my route from Latooka to Shooa. I expected to return without seeing game, when we suddenly spied a few waterbuck in the sandy bed of the river, about 300 paces distant. We made a good stalk, but I only wounded the animal at which I fired at about 150 yards, and they galloped off through the open forest. I heard the bullet from the left hand barrel strike a tree stem, which saved the antelope, but having quickly reloaded, I had a clear and steady shot at a long range as the large buck suddenly stopped and looked back. I put up the last sight for 250 yards and took a full bead. To my great satisfaction the waterbuck with a fine set of horns dropped dead. I could not measure the distance accurately as we had to descend a rocky bank, and then, crossing the bed of the Asua, to ascend the steep north bank before we arrived at tolerably level ground.
