PART II. 



PREVIOUS AUTHORS. 



In the account of Doudart de Lagree's adventuresome journey 

 through Indo-China in 1866-1868, B. Joubert has given some ac- 

 count of the geology of the parts of Yunnan crossed by the expedi- 

 tion, and a few brief notices regarding mineral deposits. ( Voyage 

 d' exploration en Indo-Chine, Francis Gamier, Paris. 1873). 



A Chinese work by Ou-Ki-Tche, at one time Viceroy of Yunnan, 

 and II akin-sen, prefect of the city of Tung-Chuan, was written in 

 1850, entitled " Tien nan kouang tchang tou lou," dealing with the 

 production of metals in Yunnan and the means employed by the 

 Chinese for their extraction and treatment. A translation of this 

 important work into French has been made by Thomas Ko, a Chinese 

 scholar, who was interpreter to the Doudart de Lagree expedition 

 and it appears in the published account of the same. In an intro- 

 duction to this work Gamier has written- -" Les dernieres parties 

 de ce travail contiennent des renseignements administratis, sta- 

 tistiques et geographiques, tres-precis et tres minutieux sur la 

 situation metallurgique du Yunnan et fappclle sur eux toute 

 1' attention des lectures. lis permettent de se faire une idee exacte 

 des richesses inoiiies que renferme cette province et de la prosperite 

 a laquelle elle peut pretendre des qu'elle aura des debouches suffisants 

 et une administration forte et honnete." 1 



E. Rocher, at first a metallurgist and later an official of the Im- 

 perial Chinese Customs Service, was sent to Yunnan during the 

 Mahomedan rebellion, in the early seventies. In a work entitled 

 " La Province Chinoise du Yun-nan," he has given some account 

 of the mines of the province then in existence and the methods 

 employed by the Chinese in the mining and the extraction of the 

 different metals. 2 



Ludvig von Loczy, the geologist attached to Count Szechenyi's 

 expedition through China, made a rapid traverse through Yunnan
