TECTONIC GEOGRAPHY OF EASTERN ASIA.

PLATES IIJ-IV. 
The march of events upon the other side of the planet dur- 
ing the past decade, the imminence of great industrial and 
commercial evolution, the probability of political changes to 
which the Russo-Japanese war is the prelude : have served to 
focus attention upon the geography and only less upon the 
geology of eastern Asiatic countries. A result of this stimu- 
lation of interest in our antipodal regions has been the large 
number of scientific expeditions which have been fitted out, 
either with the support or the encouragement of the diflferent 
governments concerned. The reports of greatest interest from 
the region, because of the perspective which they afiford, are 
by two masters of generalization in geological science — Pro- 
fessor Edouard Suess,* of Vienna, and Ferdinand Freiherr v. 
Richtofen,t the great authority upon China, and the professor 
of Geography at the University of Berlin. 
The work of Suess upon the structure of Eurasia would 
not have been possible at the time his earlier volumes were 
published (1884). It is therefore a generalization derived 
from painstaking, careful study of numerous recent reports.
