It was eight weeks since we had left Mombasa, a shorter time than had ever been taken by any caravan in Equatorial Africa to cover a distance of more than 600 miles. During the whole time we had all been, with unimportant exceptions, in good health. There had been seven cases of fever among us whites, caused by the chills that followed sudden storms of rain; the fever in all these cases disappeared again in from two to eight days, and left no evil results. Twice a number of cases of colic occurred among both whites and blacks, on both occasions resulting simply from gastronomic excesses, first in Teita and then at the Naivasha lake; and these were also cured, without evil results, by the use of tartar emetic. These sanitary conditions, exceptionally favourable for African journeys, even in the healthy highlands, were the result of the judicious marching arrangements, and, particularly among us whites, of the care taken to provide for all the customary requirements of civilised men. Tea, coffee, cocoa, meat extract, cognac to use with bad water, light wine for the evening meals, tobacco, and cigars, were always abundantly within reach; our mackintoshes and waterproof boots while marching, and the waterproof tents in camp, protected us from the wet--the chief source of fever; and we were assisted to bear our lesser privations and inconveniences by our zeal for our task, and not least by the fine balmy air which, from Teita onwards, we almost always breathed. Our saddle-horses and sumpter beasts also were, by the nourishing feed and the judicious treatment which they received, enabled to bear well the heavy labours of the march. I cannot forbear expressing the opinion that the heavy losses of other caravans, which sometimes lose all their beasts in a few days, are to be ascribed less to the climate or to the--in the lowlands, certainly very troublesome--insect pests, than to the utter inexperience of the Swahili in the treatment of animals. Had we relied merely upon our blacks, we should have left most of our beasts, and certainly all our horses, on the road to feed the vultures and hyenas. The horses would never have been allowed to cool before they drank, they never would have been properly groomed, if we had not continually insisted upon these things being done, and given a good example by attending to our saddle-horses ourselves. That the 'white gentleman' attended to his horse's wants before he attended to his own wrought such an effect upon the Swahili that at last their care for their beasts developed into a kind of tenderness. The consequence was that during the whole journey we lost only one camel, three horses, and five asses--and of these last only two died of disease, the other three having been killed by wild beasts. Of the dogs, we lost three by wild beasts--one by a rhinoceros, and two by buffaloes.
