b- THE KOREAN SYSTEM 



When speaking of the surface-configuration of South Korea, I 

 have said that it is like a checker-board, and the same feature is not 

 wanting in the Kai-ma Land. We have here mainly to deal with 

 the Thai-Päik-san Range. The Kai-ma Land is naturally divisible 

 into two portions. The right side is East Kai-ma or the Sol-bin Land 

 which presents the typical physiognomy of a plateau, especially the 

 part lying between the Hyang-san and Tyok-yu-ryong ridges, with 

 an average-height of 1,000 to 1,200 meters. (Fig. 3.) The water- 

 divide lies in the first ridge. The left side is less typical, on average 

 600 meters high, and the Tyok-yu-ryong ridge is here the water- 

 parting. (Fig. 4.)
