As we were obliged to overhaul the luggage, and repair saddles, as well as to doctor a few of the animals, whose backs had by this time become very sore, I determined to halt here two days. Provisions were very plentiful also at Simbamwenni, though comparatively dear. On the second day I was, for the first time, made aware that my acclimatization in the ague-breeding swamps of Arkansas was powerless against the mukunguru of East Africa. The premonitory symptoms of the African type were felt in my system at 10 A.M. First, general lassitude prevailed, with a disposition to drowsiness; secondly, came the spinal ache which, commencing from the loins, ascended the vertebrae, and extended around the ribs, until it reached the shoulders, where it settled into a weary pain; thirdly came a chilliness over the whole body, which was quickly followed by a heavy head, swimming eyes, and throbbing temples, with vague vision, which distorted and transformed all objects of sight. This lasted until 10 P.M., and the mukunguru left me, much prostrated in strength. The remedy, applied for three mornings in succession after the attack, was such as my experience in Arkansas had taught me was the most powerful corrective, viz., a quantum of fifteen grains of quinine, taken in three doses of five grains each, every other hour from dawn to meridian--the first dose to be taken immediately after the first effect of the purging medicine taken at bedtime the night previous. I may add that this treatment was perfectly successful in my case, and in all others which occurred in my camp. After the mukunguru had declared itself, there was no fear, with such a treatment of it, of a second attack, until at least some days afterwards. On the third day the camp was visited by the ambassadors of Her Highness the Sultana of Simbamwenni, who came as her representatives to receive the tribute which she regards herself as powerful enough to enforce. But they, as well as Madame Simbamwenni, were informed, that as we knew it was their custom to charge owners of caravans but one tribute, and as they remembered the Musungu (Farquhar) had paid already, it was not fair that I should have to pay again. The ambassadors replied with a "Ngema" (very well), and promised to carry my answer back to their mistress. Though it was by no means "very well" in fact, as it will be seen in a subsequent chapter how the female Simbamwenni took advantage of an adverse fortune which befell me to pay herself. With this I close the chapter of incidents experienced during our transit across the maritime region. CHAPTER VI. -- TO UGOGO.
