Imperial Atmospheres: Race and Climate Control on the Niger

Abstract

Abstract This essay explores how nineteenth-century environmental technologies rendered climates mobile through an examination of a British-led mission to the Niger River in West Africa in 1841. To protect white sailors from the tropical African climate, expedition authorities invited Scottish ventilation engineer David Boswell Reid to consult on the design of three iron steam ships. Using a centralized air intake connected to a wind sail, Reid created a pressurized plenum below deck whose air he medicated by treating it with chemicals. The Niger mission exemplifies how Victorian ventilating practices were informed by unilineal theories of progress in which climate served as a key index for measuring animal, vegetable, and human progress. Regions of the globe with climates similar to Britain’s were considered ideal for colonization. Tropical climates, however, were thought to have damaging effects on European bodies. Climate was also blamed for impeding the rise of civilization. Drawing on medical journals and reports, this essay discusses nineteenth-century ventilating practices in terms of their relationship to the tropical anxieties of their time. It posits climate control as an ecological mission within the broader project of British imperialism, and shows how Western ideas about thermal comfort emerged through a discursive entanglement with racial anthropology and imperial interests in the torrid zone.
