Any historian with a serious interest in China's modern economic history will be grateful for Thomas Lyons's study of the trade statistics produced by the Chinese Maritime Customs Service. Those wishing to use the Customs' statistics will find it indispensable. By means of a detailed demonstration of how to reconstruct statistics for the Fujian tea trade between 1862 and 1948, Lyons shows all the pitfalls and dangers of using Customs data, and how to deal with them.

Lyons, who has published on Fujian's and China's economic history in the past, constructs his study as a test of the tea trade statistics used by Robert Gardella and Chen Ciyu. He convincingly demonstrates that both made errors, which in the case of Gardella were of relatively minor consequence but in that of Chen of a much more serious nature. But his study is not a pedantic exercise in cliometric propriety. Rather, Lyons provides us with a sourcebook to the statistical publications of the Chinese Maritime Customs Service. He sets out in brief form the Service's organizational history and its bureaucratic structures. He then explains the Maritime Customs Service's accounts, the statistics it produced, and their dangers. He finally applies the lessons learned to a reconstruction of the Fujian tea trade.
