As remarks upon the relative value of commodities appear in various places in this diary, I shall endeavour to give a general idea how it is that I have found this plentiful country--quite beyond any other I have seen in Africa in fertility and stock--so comparatively dear to travel in. The Zanzibar route to Ujiji is now so constantly travelled over by Arabs and Wasuahili, that the people, seeing the caravans approach, erect temporary markets, or come hawking things for sale, and the prices are adapted to the abilities of the purchasers; and at such markets our Sheikh bought for us, and transacted all business. It is also to be observed that where things are brought for sale, they are invariably cheaper than in those places where one has to seek and ask for them; for in the one instance a livelihood is the consequence of trade, whereas in the other a chance purchaser is treated as a windfall to be made the most of. Now this line is just the opposite to the Ujiji one, and therefore dear; but added to those influences here, the sultans, to increase their own importance whilst having me their guest, invariably gave out that I was no peddling Arab or Msuahili, but a great Mundéwa, or merchant prince of the Wazungu (white or wise men), and the people took the hint to make me pay or starve. Then again, not having the Sheikh with me, I had to pay for and settle everything myself; and from having no variety of beads in this exclusively bead country, there was great inconvenience. Kurua now joined us, and reported the abandoned donkey dead. A cool shower of rain fell, to the satisfaction of every thirsty soul. It is delightful to observe the freshness which even one partial shower imparts to all animated nature after a long-continued drought. Chapter V. General Character of the Country Traversed--The Huts--The Geology--Productions--Land of Promise--Advice to Missionaries--Leave Ulekampuri--Return of the Expedition--Register of Temperature--Wages and Kit. 24th August.--During the last four days we have marched fifty-eight miles, and are now at our old village in Ulékampuri. As we have now traversed all the ground, I must try to give a short description, with a few reflections on the general character of all we have seen or heard, before concluding this diary. To give a faithful idea of a country, it is better that the object selected for comparison should incline to the large and grander scale than to the reverse, otherwise the reader is apt to form too low an idea of it. And yet, though this is leaning to the smaller, I can think of no better comparison for the surface of this high land than the long sweeping waves of the Atlantic Ocean; and where the hills are fewest, and in lines, they resemble small breakers curling on the tops of the rollers, all irregularly arranged, as though disturbed by different currents of wind.
