ABSTRACT In the second half of the nineteenth century, mechanics institutes proliferated across the Australian colonies at such a rate that, by 1900, they were more widespread, proportional to population, than in Britain. This article examines the first 30 years of their development in colonial Victoria to offer a new interpretation of their deep entanglement with settler colonial liberalism. As in Britain, the Victoria mechanics institutes largely failed to deliver technical education to working-class men. However, the men who propelled their proliferation had much wider hopes for their pedagogic function in the settler colony. This article examines how the twin forces of political liberalism and settler colonialism underwrote and shaped mechanics institutes in mid-nineteenth-century Victoria. Examining the ideas of colonial liberals who propelled their proliferation and the activities that took place within them, it becomes clear that these institutes were imagined to cultivate certain kinds of settler Britons, capable of bearing the freedoms of an emerging settler modernity. At the same time, moreover, they both legitimated and implemented a settler colonial project of dispossession and demographic replacement. Mechanics institutes, I argue, were thus agents of both settler colonial destruction and liberal cultivation.
