Shows natives crossing a stream, typical scene in this part of Africa. They seldom have bridges. Simply wade in water and drink and fill water jars. Even the whites are careless of drinking water. Tanganyika water used without boiling and at Victoria Falls Zambezi water used. On Lualaba water supposed to be filtered but I found part of a lily leaf in my glass one day.
