The history of labor migration is largely, to echo PATIO’s aspiration, a history of transfers: labor, skill, and knowledge moving from one place to another. The labor migration supporting commodity production in colonial Sumatra is one such case. By the early twentieth century, plantation companies had moved hundreds of thousands, if not millions, of indentured laborers from China, India, and Java across the Pacific and Indian Oceans to supply workforces for some of the world’s largest tobacco and rubber plantations. Their role was indispensable; the indentured were the planters in the actual sense, the people who planted seeds and cared for plants. Their movement constituted the transnational and transimperial networks to which modern Western empires owed their wealth.
Labor in motion, however, entailed labour in station. Plantation managers and migration officers stopped, checked, selected, documented, isolated, and at times dismissed potential workers at different transitory nodes before they arrived at plantation estates. If architectural history has something distinctive to offer to the study of labor migration, it is its capacity to zoom in on those nodes to understand how the plantation system controlled its most important resource. Thinking both along and against flows, I examine the construction of labour mobility that sustained the region’s commodity industries, a process involving a constellation of buildings in more than one hundred locations, from Semarang to Hong Kong, to facilitate the systematic documentation and selection of labourers as well as their transportation.
