Reisz, The Yunnan-Burma frontier in China's frontier space. 2 Yet despite the attention paid to Maritime Customs operations, little attention has been paid to the role of the Customs in shaping understandings of the Chinese frontier.In particular, the increasing role of the 'Maritime' Customs in regulating overland trade (and therefore in shaping overland frontiers) has been largely ignored. Focusing on the Sino-Burmese frontier in Western Yunnan and making use of photographic sources, this article argues that the Maritime Customs understood the Chinese frontier not as a line on a map but as a road across it, shaped by geographies not of space (as in conventional cartography) but of networks (for people and goods to move from one point to another).Roads are essential to understanding Qing society and trade, yet compared to the welltraveled history of railways and shipping, 3 research into the road network in late Qing China is in its infancy. 4 Nowhere was the road network more important than in Yunnan, where railway construction was difficult and where the silk roads had crossed for millennia, but caravan routes have received far more attention than the roads themselves. 5 The neglect of roads is surely undeserved; as Robert Bickers has argued, 'infrastructural globalization… is not simply a European or colonial story… [and] if the history of technology can provide a "hidden history" of European integration… it can also provide a cognate history of the emergence of the modern Chinese state.' 6 New forms of transportation may literally reshape the state, creating long-distance empires and new borders, and producing what has been called 'time compression… in the sense that places and spaces… experience intensified interaction.' 7As well as creating tangible connection, roads are also powerful visual symbols which, as represented in photography, exerted a profound influence on understandings of space. 8 For Joan Schwartz and James Ryan, 'geography and photography became partners in picturing place… [and] making "imaginative geographies"… the mechanism by which people come to know the world and
