ART. l.—B. KOTO: 



There are still two other ridges of similar structure and the same 

 orientation, but of short extent, and topographically insignificant. 

 They all lie on the west side of the Nak-tong Gang. 



So much for the ruptured ridges which constitute the Thai- 

 Päik-san Mountains. 



ß) The Syo-Pâik-San Eangb. 



The Korean System in South Korea comprises a considerable 

 number of ridges which, so far as they have come under my observa- 

 tion, are all of tectonic blocks, and are separable into two groups. I 

 have already given characteristics of a group which is provisionally 

 called the Thai-Päik-san Range. As will be seen in the foregoing- 

 pages, the approximate trend of its members is N.N.W. to S.S.E., 

 conforming to the general form of the coast of southern Korea, which 

 form has an intimate genetic relation to the direction of the 

 mountains.

Figs. I and 2.— The two are really a continuous profile of the Han Land or South Korea from the west to the east 

 across Chhyung-chhyBng Do and Kyöng-syang Do, traversing oir 'the way the Byo-PSlk-san Range 

 from Tybk-nai Pass to Yuk-sim-nyöng (C90 m.) In the above, and the Thui-1'äik-san Range 

 between Eui-Syöng and Yöng-d'bk in the lower figure. The Syo-Paik-san in Fig. 1. marks the 

 boundary of two provinces, forming at the same time the watershed between the Keum-(>ang ami 

 the Nak-tong-Qang, the former discharges its waters to the Yellow Sea at the free port of Kun- 

 -.iii, the latter empties into the sea near the Japanese colony of Fusan.
