Timbouctou, voyage au Maroc au Sahara et au Soudan, Tome 2 (de 2)

The account follows an overland expedition across Morocco into the Sahara and the Sudan, tracing caravan routes, mountain passes and desert plains. It describes daily life on camels, loading methods and saddle practices, encounters with guides and local inhabitants, and anxieties about banditry along isolated stretches. The author records archaeological remains and petroglyphs, sketches erosion forms, hamada plateaus and river beds such as the Draa, and notes weather events, vegetation and wildlife. Practical preparations, bivouacs and relations with regional notables recur alongside geological, topographical and ethnographic observations that combine travel narrative with scientific description.
