Making the Palace Machine Work: Mobilizing People, Objects, and Nature in the Qing Empire brings the studies of institutions, labour, and material cultures to bear on the history of science and technology by tracing the workings of the Imperial Household Department (Neiwufu) in the Qing court and empire. An enormous apparatus that employed 22,000 men and women at its heyday, the Department operated a "machine" with myriad moving parts. The first part of the book portrays the people who kept it running, from technical experts to menial servants, and scrutinises the paper trails they left behind. Part II uncovers the working principles of the machine by following the production chains of some of its most splendid products: gilded statues, jade, porcelain, and textiles. Part III examines the complex task of managing living organisms and natural environments, including lotus plants grown in imperial ponds in Beijing, fresh medicines sourced from disparate regions, and tribute elephants from Southeast Asia. First, the innovative framework of conceiving the Qing court as a 'machine' unifies the chapters into a coherent whole; the metaphor of a machine enables the authors to illuminate the enormous Qing court apparatus as solid structures and as mobile processes. Second, scholars from different national background, expertise, and generations working together, creating a unique multidisciplinary study that can be instructive for scholars working in other periods or geographical regions. Third, the inter-species perspective, especially evident in Part 3 of the book, breaks new ground by introducing an environmental and ecological awareness to the study of technology and material cultures. This is a new direction in the China field.
