12th.--The caravan got under way by 6 A.M., and we marched thirteen miles to a village in the southern extremity of the Unyambéwa district. Fortunately tempers, like butterflies, soon change state. The great distractor Time, together with the advantage of distance, has produced such a salutary effect on the Beluches' minds, that this morning's start was accomplished to the merry peals of some native homely ditty, and all moved briskly forward. This was the more cheering to me because it was the first occasion of their having shown such signs of good feeling as singing in chorus on the line of march. The first five miles lay over flattish ground, winding amongst low straggling hills of the same formation as the whole surface of the Unyamuézi country, which is diversified with small hills composed of granite outcrops. As we proceeded, the country opened into an extensive plain, covered, as we found it at first, with rich cultivation, and then succeeded by a slender tree-forest, amongst which we espied some antelopes, all very wary and difficult of approach. At the ninth mile was a pond of sweet water, the greatest luxury in the desert. Here I ordered a halt for half an hour, and made a hearty breakfast on cold meat, potted Tanganyika shrimps, rozelle jelly, with other delicacies, and coffee. The latter article was bought from the Kazé merchants. Towards the close of the journey a laughable scene took place between an ivory caravan of Wasukuma and my own.[52] On nearing each other, the two Kirangozis or leaders slowly advanced, marching in front of the single-file order in which caravans worm along these twisting narrow tracks, with heads awry, and eyes steadfastly fixed on one another, and with their bodies held motionless and strictly poised, like rams preparing for a fight, rushed in with their heads down, and butted continuously till one gave way. The rest of the caravan then broke up their order of march, and commenced a general mêlée. In my ignorance--for it was the first time I had seen such a scrimmage--I hastened to the front with my knobbed stick, and began reflecting where I could make best use of it in dividing the combatants, and should no doubt have laid on if I only could have distinguished friend from foe; but both parties, being black, were so alike, that I hesitated until they stopped to laugh at my excited state, and assured me that it was only the enactment of a common custom in the country when two strange caravan-leaders meet, and each doubts who should take the supremacy in choice of side. In two minutes more the antagonists broke into broad laughter, and each went his way.
