We halted three days on the western extremity of the Usagozi district, detained by another unpleasant phenomenon. My companion, whose blood had been impoverished, and whose system had been reduced by many fevers, now began to suffer from “an inflammation of a low type, affecting the whole of the interior tunic of the eyes, particularly the iris, the choroid coat, and the retina;” he describes it as “an almost total blindness, rendering every object enclouded as by a misty veil.” The Goanese Valentine became similarly afflicted, almost on the same day; he complained of a “drop serene” in the shape of an inky blot--probably some of the black pigment of the iris deposited on the front of the lens--which completely excluded the light of day; yet the pupils contracted with regularity when covered with the hand, and as regularly dilated when it was removed. I suffered in a minor degree; for a few days webs of flitting muscæ obscured smaller objects and rendered distant vision impossible. My companion and servant, however, subsequently, at Ujiji, were tormented by inflammatory ophthalmia, which I escaped by the free use of “camel-medicine.” Quitting Usagozi on the 26th January, we marched through grain fields, thick jungle-strips, and low grassy and muddy savannahs to Masenza, a large and comfortable village of stray Wagara or Wagala, an extensive tribe, limiting Unyamwezi on the S. and S.E., at the distance of about a week’s march from the road. On the 27th January, after traversing cultivation, thick jungles, and low muddy bottoms of tall grass chequered with lofty tamarinds, we made the large well-palisadoed villages of the Mukozimo district, inhabited by a mixture of Wanyamwezi, with Wagara from the S.E. and Wawende from the S.W. The headman of one of these inhospitable “Kaya,” or fenced hamlets, would not house “men who ride asses.” The next station was Uganza, a populous settlement of Wawende, who admitted us into their faubourg, but refused to supply provisions. The 29th January saw us at the populous and fertile clearing of Usenye, where the mixed races lying between the Land of the Moon eastward, and Uvinza westward, give way to pure Wavinza, who are considered by travellers even more dangerous than their neighbours. Beyond Usenye we traversed a deep jungle where still lingered remains of villages which had been plundered and burned down by the Wawende and the Watuta, whose hills rose clearly defined on the right hand. Having passed the night at Rukunda, or Lukunda, on the 31st January we sighted the plain of the Malagarazi River. Northwards of the road ran the stream, and the low level of the country adjoining it had converted the bottoms into permanent beds of soft, deep, and slippery mire. The rest of the march was the usual country--jungle, fields, and grasses--and after a toilsome stretch, we unpacked at the settlement of Wanyika.
