The agricultural and forest products of British West Africa — Context and Discussion

Cotton, War, and the Promise of Improvement

The preface, written by editor Wyndham R. Dunstan, treats the Great War as a catalyst. Dudgeon’s own chapters on cotton trace a deliberate improvement program: in Northern Nigeria, “American Upland” seed was perfected; in the south, an improved native cotton approached “Middling American” grade. The language is that of a colonial agronomist—precise about seed types and commercial grades—but the underlying narrative is one of fragile progress. The war disrupted development, yet it also created demand for margarine and edible oils, boosting palm kernels. Dudgeon does not celebrate; he reports. The future of cotton, he writes, “chiefly depends on effective action being taken on commercial lines.” That conditional phrasing—depends on—hints at the uncertainty beneath the official optimism.

The Shea Butter Trade and the Geography of Exchange

One of the most vivid passages describes shea butter, the “cooking oil of the ultra-forest country.” Dudgeon notes that the prepared butter is carried by Haussa traders who visit Ashanti to buy kola, and that it fetches a high price in Kumassi. He also traces a second route: canoes bring salt from Adda up the Volta to Yeji and Daboya, and shea butter moves back down. The analysis from the Imperial Institute confirms the butter’s quality, but Dudgeon’s real interest is in the movement of goods. He records prices—beeswax at £6 15s. per cwt., guinea-fowls at threepence each—and the means of transport: head-loads, calabashes, canoes. These details build a picture of an economy where value is measured in shillings and carried on foot.

Rubber, Dyes, and the Limits of Observation

Dudgeon’s account of rubber in the Northern Territories is notably cautious. A species of Landolphia was found near the Black Volta, and initially thought to be plentiful, but later reports indicated it “occurs rather rarely.” Another species had been mistaken for it. The passage is a small case study in the difficulty of colonial botany: plants are misidentified, specimens are dwarfed by annual grass fires, and the hoped-for root rubber does not develop. Similarly, when describing indigo preparation, Dudgeon admits the process “has not been carefully observed” and is “probably similar” to methods used elsewhere. These admissions of uncertainty are rare in a handbook that otherwise projects authority, and they give the reader a sense of the gaps in knowledge that the book was meant to fill.

Dudgeon’s handbook is best read not as a definitive survey but as a document of its moment—a colonial inventory that reveals as much about the limits of imperial knowledge as about the products it catalogs. The reader may find the most rewarding passages not in the tables of yields or botanical descriptions, but in the asides: the guinea-fowls carried in baskets, the bees hived in calabashes, the cattle that must be killed before entering the tsetse fly belt. These details resist the book’s official purpose and offer a glimpse of the human and ecological complexity that no handbook can fully contain.
