Correspondence (1911-1913), a personal journal, and a collection of photographs created by David Hoffman, an engineer from Butte, Montana, who traveled to Africa in 1911 as a member of a geographical and topographical survey team prospecting for oil, gold and copper. He spent 16 months working on the Brunton survey in the Belgian Congo. Hoffman describes his stops at Brussels, Waterloo, Antwerp, Teneriffe, Sierra Leone, Portuguese Congo, Luibi (a village), and Kinshasa. Hoffman's journal gives an account of his sea voyage to Europe and Africa. The photographs depict the landscape of the Belgian Congo, and the gatherings, village life, workers, and forms of dress of the local people.
