[We now come to a disaster which cannot be exaggerated in importance when we witness its after effects month by month on Dr. Livingstone. There can be little doubt that the severity of his subsequent illnesses mainly turned upon it, and it is hardly too much to believe that his constitution from this time was steadily sapped by the effects of fever-poison which he was powerless to counteract, owing to the want of quinine. In his allusion to Bishop Mackenzie's death, we have only a further confirmation of the one rule in all such cases which must be followed, or the traveller in Africa goes--not with his life in his hand, but in some luckless box, put in the charge of careless servants. Bishop Mackenzie had all his drugs destroyed by the upsetting of a canoe, in which was his case of medicines, and in a moment everything was soaked and spoilt. It cannot be too strongly urged on explorers that they should divide their more important medicines in such a way that a _total loss_ shall become well-nigh impossible. Three or four tin canisters containing some calomel, Dover's powder, colocynth, and, above all, a supply of quinine, can be distributed in different packages, and then, if a mishap occurs similar to that which Livingstone relates, the disaster is not beyond remedy.] * * * * * _20th January, 1867._--A guide refused, so we marched without one. The two Waiyau, who joined us at Kande's village, now deserted. They had been very faithful all the way, and took our part in every case. Knowing the language well, they were extremely useful, and no one thought that they would desert, for they were free men--their masters had been killed by the Mazitu--and this circumstance, and their uniform good conduct, made us trust them more than we should have done any others who had been slaves. But they left us in the forest, and heavy rain came on, which obliterated every vestige of their footsteps. To make the loss the more galling, they took what we could least spare--the medicine-box, which they would only throw away as soon as they came to examine their booty. One of these deserters exchanged his load that morning with a boy called Baraka, who had charge of the medicine-box, because he was so careful. This was done, because with the medicine-chest were packed five large cloths and all Baraka's clothing and beads, of which he was very careful. The Waiyau also offered to carry this burden a stage to help Baraka, while he gave his own load, in which there was no cloth, in exchange. The forest was so dense and high, there was no chance of getting a glimpse of the fugitives, who took all the dishes, a large box of powder, the flour we had purchased dearly to help us as far as the Chambeze, the tools, two guns, and a cartridge-pouch; but the medicine-chest was the sorest loss of all! I felt as if I had now received the sentence of death, like poor Bishop Mackenzie.
