THE GEOLOGICAL SURVEY OF 

 CHINA 



In the process of reconstruction, and adapta- 

 tion to modern conditions, which China is at 

 present undergoing, the introduction of scienti- 

 fic research and, concurrently, the establish- 

 ment of scientific government organs is abso- 

 lutely essential to the success of the movement. 

 To a narrow circle of interested mining men 

 and scientists, it has long been known that the 

 G-eological Survey of China, established in 

 1916, has been making steady progress, both in 

 the way of supporting the mining industry 

 with espert advice, and in accumulating scien- 

 tific data and material to such an extent that 

 it has been recognized abroad as a factor in 

 inaugural ceremonies by and in the presence 

 ploration of the earth. 



But the work of the Geological Survey has 

 been carried on in quite an unostentatious way, 

 and little has transpired about its activities 

 outside of professional circles, until July 

 seventeenth, when the institution was offieially 

 thrown open to the public, with appropriate 

 inaugural ceremonies by and in the presence 

 of H. R. President Li Yuan Hung. 



Before giving an account of these exercises, 

 it may be well briefly to review the develop- 

 ment of the survey and its achievement up to 

 the present time. 



Geological Government Surveys have been 

 established during the last half century in all 

 civilized states. The principal aims of those 

 institutions are threefold: namely, (1) to pro- 

 mote the knowledge of the mineral resources 

 of tihe country, (2) to carry on a general geo- 

 logic survey of the Avhole country upon a uni- 

 form scale, and (3) to undertake scientific 

 geological research. 



In the first of these fields the Geological 

 Survey of China can already point to a credit- 

 able series of achievements, such as the dis- 

 covery and survey of a large number of iron-
