Archer travelled overland from Uganda to Sudan to take up his new appointment, walking from Nimule to Rejaf and then travelling by steamer down the Bahr al Jabal to Khartoum.
The river continues north to Nimule, where it enters South Sudan and becomes known as the Bahr al Jabal ('Sea of the Mountain', possibly from Nahr al Jabal, 'River of the Mountain').
The Bahr al Jabal passes through Juba, the capital of South Sudan, which is the southernmost navigable point on the Nile river system, and then to Kodok, the site of the 1898 Fashoda Incident that marked an end to the 'Scramble for Africa'.
Bahr al Jabal was the former name of the state of Central Equatoria.
