"Voyage scientifique à travers l'Afrique occidentale" by Auguste Chevalier is a scientific travelogue written in the early 20th century. It documents a French colonial mission across the Soudan français, Sénégal, and Casamance to survey flora and other natural resources, emphasizing economically useful plants, cultivation methods, and field-based observations interwoven with notes on landscapes and local life.
The opening of this account presents a preface by Prof. Édouard Heckel outlining the mission’s composition, goals, and acclaim at the Paris exposition, and emphasizing the breadth of Chevalier’s prior collections focused on useful species such as bourgou and dye plants. In his introduction, the botanist explains that the text is drawn from rough field notes taken under difficult conditions, thanks numerous supporters and assistants, sketches his wide itinerary from the Niger’s bend to Tombouctou and later through Senegal, and situates his work among earlier naturalists. The first chapter begins at Bammako with closely observed portraits of terrain, sacred groves, village customs, and detailed botanical inventories (karité, figs, raphia, lianas, ferns), down to Latin names and local uses. He examines a nearby wheat experiment and kitchen-garden trials, then follows the Niger through villages like Langana and Kangaba, noting textile plants (Hibiscus cannabinus), rubber-yielding Landolphia, fruit trees, and crops. Throughout, he records ruined settlements and gold pits linked to recent conflicts, marigots and soils, wildlife signs, and the cultivation potential of specific sites, establishing the work’s blend of science, economy, and on-the-ground travel narrative.
