Volume VI Part 3 of Science and Civilisation in China contains two separate works. The first, by Christian Daniels, is a comprehensive history of Chinese sugarcane technology from ancient times to the early twentieth century. Dr. Daniels includes an account of the contribution of Chinese techniques and machinery to the development of world sugar technology in the premodern period, devoting special attention to the transfer of this technology to the countries of Southeast and East Asia in the period after the sixteenth century. The second, by Nicholas K. Menzies, is a history of forestry in China. Dr. Menzies identifies a tradition of forest management that can be traced to the earliest Chinese written records, and describes methods of silviculture, and the major timber species used in Chinese forestry. A final section compares China's history of deforestation with the cases of Europe and Japan. Each of these works will interest scholars of Chinese science, culture, and ancient agriculture as well as historians of science.
