An explorer's account describes an expedition from the East African coast into central Africa to locate and relieve the ailing missionary David Livingstone. The narrative follows preparations in coastal towns, the assembling of caravans, and arduous marches through varied regions, swamp and savanna, with detailed encounters with Arab traders, local chiefs, and hostile and hospitable communities. It records illness, skirmishes, desertions, and logistical hardships alongside geographic and ethnographic observations, sketches of routes and settlements, and the practical challenges of 19th-century African exploration leading up to the eventual meeting with Livingstone.
