H. R. Davies (1865–1950) was an English army officer and member of the British intelligence service. Between 1894 and 1900 he was asked by the British government to lead survey expeditions into the modern Chinese province of Yunnan to discover possible routes for a railway connecting British-occupied Burma with the upper Yangtze river and through to Sichuan. This book contains an account of his travels though Yunnan province, written as a travelogue and first published in 1909. The region had been little explored by westerners before Davies' expeditions, and this is the first detailed description of Yunnan from a European traveller. The society, diverse indigenous cultures, geography, economy and political situation of the province are described in detail, with an introductory three chapters on the political context of the expeditions, and on railway construction in south-east Asia in the late nineteenth century.
