From the basin of Utinda we ascended past a few cones dominating a ridge which enclosed it on the south and south-east, and, after surmounting two other ridges separated by well-watered valleys, we arrived on the airy upland of grassy Uhobo, 4,900 feet above sea-level. A little later Kaibuga entered into our camp. This chief was of the Wahuma settled among the Balegga, whose grounds overlooked the plain of Kavalli and the south end of the Nyanza, and whose territory extended to the debouchure of the Semliki. He urged active hostilities, as Uhobo belonged to Kabba Rega. Naturally we smiled at this, as we had not seen the semblance of a single enemy, though it is true that the Uhobo natives had disappeared from view at our approach. At this instant a picquet signalled the advance of a column of Kabba Rega’s people armed with guns, and two companies of Zanzibaris were mustered by Lieutenant Stairs and Captain Nelson, the latter of whom had so improved by the diet of Kavalli and Mazamboni that he was fit for any work. After proceeding about two miles they met the small party of the Pasha’s people carrying the dead body of Captain Casati’s faithful servant Okili, for whom Casati entertained deep affection. He had been shot through the forehead by a rifle-ball. It appears that while the Soudanese had been bathing in a stream south of Uhobo, the column of the Wara Sura happened to be observed marching in a pretty disciplined manner with two flags towards them, and a few minutes later would have surprised them, but the whole party hastily dressed, and, snatching their rifles, opened fire on them. Three of the enemy fell dead, and Okili was shot by the fire that was returned. On the approach of the Zanzibaris the Wara Sura fled, and were pursued for three miles, but no further casualties occurred. [Sidenote: 1889. May 12. Mboga.] A severe rainstorm, lasting seven hours, fell during the night, and in the morning when marching to Mboga we were involved in cloud and mist. As the day advanced, however, Ruwenzori thrust its immense body into view far above the vapours rising from the low Semliki Valley, and every now and then the topmost cones gathered the cloudy fleeces and veiled their white heads from view. As we advanced nearer each day to the range we were surprised that we were not able to discover so much snow as we had seen at Kavalli, but on reflection it became evident that the line of snow became obscured from view by an advanced ridge, which the nearer we approached impeded the view the more. We observed also that the lofty mountain range assumed the form of a crescent; Ajif Mountain forming the northern end and the Twin Peak shoulder to the west the other end; and further, that beyond Ajif, which I estimated at about 6,000 feet above the sea, there was a steady and perceptible rise to the snow line, and then a sudden uplift to the proud height of from 2,000 to 5,000 feet higher, most of which was under snow.
