ters) of Nam-uön 1 ^ Yuk-sim-nyöng 2) (690 m.), Tög-yu-san 3) and then 

 Pu-hang-nyöng 4) , it finally comes to end at Chik-chi-san 5 -' near the 

 Chhyu-phung-nyöng pass. In its northern prolongation it forms the 

 boundary ridge of two provinces, and Tög-yu-san, its highest point, is 

 frequently mentioned by native geographers. The steep side of the 

 ridge by this time lies on the west in contrast to the two preceding 

 ridges ; consequently this together with the axial ridge forms a sort of 

 crust-block or Horst, similar in structure to the Thai-Päik-san. A 

 narrow table of Un-bong 6) , 370 m. high, lies between the ascents of 

 Yö-uün-chhi (west) and Phal-hyöng-chhi (east side). 



iv. The Pi-hong-chhi Ridge. — This westernmost member starts 

 from the head-land of Thyön-goan-san 7) , and advances by Sä-chä-san 8J 

 Kamnamu-chhi 9) (150 m.), Tong-pok l0) , the Pi-hong-chhi pass 10 (215 

 m.) of Nam-uön, the Pha-kokai 12) (310 m.) of Chin-an 13) , ending at the 

 same point as the preceding. 



The ridge is like in structure to its eastern neighbour, and 

 between them is situated the depression of Nam-uon. 



The foregoing four members, as has been already stated, converge 

 to the Chhyu-phung-nyöng pass where the apex of the gigantic 

 Chiri-san wedge lowers to 200 meters, and the said pass affords an 

 easy passage from the north to the south. The point is just midway 

 of the projected Fusan-Seoul Railway. To the feaiher-stmcture of 

 these ridges, 1 shall come back in later pages.
