It was therefore fortunate for me that I overtook him at Kiora; though he was about to prove a sore incumbrance to me, for he was not able to walk, and the donkey-carriage, after the rough experience of the Makata valley, was failing. I could not possibly leave him at Kiora, death would soon overtake him there; but how long I could convey a man in such a state, through a country devoid of carriage, was a question to be resolved by circumstances. On the 11th of May, the third and fifth caravans, now united, followed up the right bank of the Mukondokwa, through fields of holcus, the great Mukondokwa ranges rising in higher altitude as we proceeded west, and enfolding us in the narrow river valley round about. We left Muniyi Usagara on our right, and soon after found hill-spurs athwart our road, which we were obliged to ascend and descend. A march of eight miles from the ford of Misonghi brought us to another ford of the Mukondokwa, where we bid a long adieu to Burton's road, which led up to the Goma pass and up the steep slopes of Rubeho. Our road left the right bank and followed the left over a country quite the reverse of the Mukondokwa Valley, enclosed between mountain ranges. Fertile soils and spontaneous vegetation, reeking with miasma and overpowering from their odour, we had exchanged for a drouthy wilderness of aloetic and cactaceous plants, where the kolquall and several thorn bushes grew paramount. Instead of the tree-clad heights, slopes and valleys, instead of cultivated fields, we saw now the confines of uninhabited wilderness. The hill-tops were bared of their bosky crowns, and revealed their rocky natures bleached white by rain and sun. Nguru Peak, the loftiest of the Usagara cones, stood right shoulderwards of us as we ascended the long slope of dun-grey soil which rose beyond the brown Mukondokwa on the left. At the distance of two miles from the last ford, we found a neat khambi, situated close to the river, where it first broke into a furious rapid. The next morning the caravan was preparing for the march, when I was informed that the "Bana Mdogo"--little master--Shaw, had not yet arrived with the cart, and the men in charge of it. Late the previous night I had despatched one donkey for Shaw, who had said he was too ill to walk, and another for the load that was on the cart; and had retired satisfied that they would soon arrive. My conclusion, when I learned in the morning that the people had not yet come in, was that Shaw was not aware that for five days we should have to march through a wilderness totally uninhabited. I therefore despatched Chowpereh, a Mgwana soldier, with the following note to him:--"You will, upon receipt of this order pitch the cart into the nearest ravine, gully, or river, as well as all the extra pack saddles; and come at once, for God's sake, for we must not starve here!"
