On the 18th of October we were at Amiri Rapids, and the second Zanzibari showed symptoms of small-pox. So far we had been remarkably free of the disease, despite the fact that there were from ten to twenty sufferers daily in the camp since arriving at the settlement of the Batundu. Out of 620 Zanzibaris who were ordered to be vaccinated, some few constitutions might possibly have resisted the vaccine; but no more decided proof of the benefits resulting to humanity could be obtained from Jenner’s discovery than were furnished by our Expedition. Among the Manyuema, Madis, and native followers, the epidemic had taken deadly hold, and many a victim had already been tossed into the river weighted with rocks. For this was also a strange necessity we had to resort to, to avoid subsequent exhumation by the natives whom we discovered to be following our tracks for the purpose of feeding on the dead. One of the Zanzibari headmen while acting as coxswain of a canoe was so stung by wasps at this camp that he despaired of his life, and insisted that his will should be written, wherein he made his brother, then with us, his sole legatee. I conformed to his wish in a clerkly fashion that pleased him well, but I also administered a ten-grain dose of carbonate of ammonium hypodermically, and told him he should reach Zanzibar in spite of the vicious wasps who had so punished him. The next day he was a new man, and boasted that the white man’s medicines could cure everything except death. [Sidenote: 1888. Oct. 18. Amiri Falls.] After moving to the top of Amiri Rapids, a series of misfortunes met us. Some few of the flighty-headed untrained men of the rear-column rushed off to the plantain plantations without a leader or authority, and conducted themselves like children. The natives surrounded them and punished them, wounding three. Two others, one suffering from a palpitation of the heart, and another feeble youth, had left the trail to hide from the rear-guard. Up to date, we had lost since 1st of September, nine Zanzibaris killed, one from suicide, one from ulcers, and two were missing. Of the Manyuema contingent, fifteen had been killed or had died from small pox, and eighteen Madis had either been killed or had perished from the pest. Total loss, forty-four deaths within forty-nine days. [Sidenote: 1888. Oct. 19. Amiri Falls.]
