monograph by Chen Han-seng; and maps and tables prepared by Guy Arbellot, with the assistance of Stephanie Gavin and Nicholas Thorner Daniel Thorner's agrarian atlas of India, fully prepared for the press by 1965, was belatedly published two decades later thanks to the untiring efforts of Alice Thorner. The heart of the atlas consists of a series of descriptions written by the historian Chen Han-seng to illustrate his division of the subcontinent into 21 agrarian regions. The review begins by describing Chen's regionalization and conveying some sense of the quality of his descriptions of individual regions. It then raises analytical issues related to Chen's understanding of agrarian capitalism and his reluctance to characterize developments in the late colonial countryside in terms of the growth of capitalism. The conclusion contrasts two conceptions of agrarian capitalism, rejecting the idea of a historical prototype. Keywords: South Asian agrarian history, colonial India, agrarian capitalism, agrarian regions, agrarian atlas THE ATLASThe atlas under review is the outcome of collaboration between Daniel Thorner and Chen Han-seng. It has two crucial components. The first is a monograph on the regional differentiation of South Asia c.1930 written by Dr Chen in the late 1940s and early 1950s. The second is a cartographic representation of the 21 regions into which Chen divided South Asia, pursued and completed by Thorner in Paris between 1960 and 1965, with the aid of a research team.
