25th.--We left Ulékampuri at 1 A.M., and marched the last eighteen miles into Kazé under the delightful influence of a cool night and a bright full moon. As the caravan, according to its usual march of single file, moved along the serpentine footpath in peristaltic motion, firing muskets and singing "the return," the Unyanyembé villagers, men, women, and children, came running out and flocking on it, piercing the air with loud shrill noises, accompanied with the lullabooing of these fairs--which, once heard, can never be mistaken. The crowd was composed in great part of the relatives of my porters, who evinced their feelings towards their adult masters as eagerly as stray deer do in running to join a long-missing herd. The Arabs, one and all, came out to meet us, and escorted us into their depôt. Captain Burton greeted me on arrival at the old house, and said he had been very anxious for some time past about our safety, as numerous reports had been set afloat with regard to the civil wars we had had to circumvent, which had impressed the Arabs as well as himself with alarming fears. I laughed over the matter, but expressed my regret that he did not accompany me, as I felt quite certain in my mind I had discovered the source of the Nile. This he naturally objected to, even after hearing all my reasons for saying so, and therefore the subject was dropped. Nevertheless, the Captain accepted all my geography leading from Kazé to the Nile, and wrote it down in his book--contracting only my distances, which he said he thought were exaggerated, and of course taking care to sever my lake from the Nile by _his_ Mountains of the Moon. It affords me great pleasure to be able to report the safe return of the expedition in a state of high spirits and gratification. All enjoyed the salubrity of the climate, the kind entertainments of the sultans, the variety and richness of the country, and the excellent fare everywhere. Further, the Beluches, by their exemplary conduct, proved themselves a most efficient, willing, and trustworthy guard, and are deserving of the highest encomiums; they, with Bombay, were the life and success of everything, and I sincerely hope they may not be forgotten. The Arabs told me I could reach the N'yanza in fifteen to seventeen marches, and I returned in sixteen, although I had to take a circuitous line instead of a direct one. The provisions, too, just held out. I took a supply for six weeks, and completed _that_ time _this_ day. The total road-distance there and back is 452 miles, which, admitting that the Arabs make sixteen marches of it, gives them a marching rate of more than fourteen miles a- day. The temperature is greater at this than at any other time of the year, in consequence of its being the end of the dry season; still, as will be seen by the annexed register of one week, the Unyamuézi plateau is not unbearably hot.
