The source of the Blue Nile

A narrative of a journey from Khartoum across the Sudan into western Abyssinia to Lake Tsana and back by the valley of the Atbara, combining travelogue, geographic observation, and ethnographic notes. The account records landscapes, village life, markets, churches and festivals, local rulers and diplomatic concerns, sanitary and medical impressions, and encounters with flora and fauna. Illustrations, maps, and an entomological appendix accompany practical descriptions of routes, ferries, and caravan travel, and occasional reflections on regional politics and commercial opportunities.
