JOUENEYS THROUGH KOREA. 151 



Korea, and the Commissioners in their reports '\ which have just 

 now been made pubhc, in the main adopt my view concerning 

 the Korean mountain systems. 



Korea is, geologically speahing, a land of diagonal " Ilorst ". 

 The fundamental geologic and topographic hneaments traverse the 

 peninsula diagonally from the southwest to the north-east as 

 prolongations of the mountains of South China, and of a later date 

 dislocations of the earth's crust have given to the peninsula its 

 present shape which in its outline resembles that of Italy at the 

 other end of Eurasia. The character of the diagonal " Horst " is 

 typically developed in South Korea, while the northern half has 

 a frame-work of a somewhat different orientation. 



The region now under discussion, which comprises nearly a 

 quarter of the peninsular area, lies between 33 and 36 N., and 

 includes witliin it tlie island of Chißi-jya far off the southwest coast. 

 The east half is the province of Kyöng-sang-Ih, and the west half 

 Clußl-la-Do. The diagonal So-paik-san range with its one-sided, 

 feather-like, minor ridges traverses the latter, and the meridional
