JOURNEYS THROUGH KOREA. 85 



From the pass a view can be liad of tlie inner Chiri-san on 

 the southwest (PI. XVI. Jhj. 3). We discovered at least two 

 parallel ridges of the Pam-clihl type instead of a single ridge, all 

 coming suddenly to an end at the west bank of tlie Nam-gang. 

 To the east (PI. XYII. //j/. 1) we looked down upon the hilly ^^ 

 lowland (70 m) of the Xah-toiig-gang backed by high ridges of 

 the green eruptive formation of Kyöng-sang-Do beyond the river. 



The relief of the meridional Nak-tong lowland extending 00 

 km is coulisse-like (PI. XVII. fig. 1) ; the uplifted edges of the 

 sedimentary beds, running parallel to one another in the direction 

 of the axis of tlie l)asin, are basseted westwards with model-like 

 regularity (see figure 1). I have already touched upon the phy- 

 siography of this basin in the first traverse '"\ 



The eastern side of tlie Chhyöng-mörl-cJihl is precipitous (PJ. möri-chhi 



PASS 



XVII. fig. 2). The rock exposed is hue eye-gneiss dipping west- 

 wards contrary to our. expectation. At the foot is a stream, the 

 east bank of which, I was sarprised to find, is a cliff composed 

 of the Nak'tong ssries slowly slanting to the east. 



From the place called Chap-chid '' on tlie river-side we had 

 to travel 10 km to Sam-ga^^, after crossing two low but steep 

 hill bassets ''^ with an avertige height of 70 m (PI. XVH. fig. o). 

 These consist of tabular, gray musco vite- sandstone intercalated 

 with a few beds of green micaceous marl with an uneven sedi- 

 mentation-plane (the strike N. 20" E., the dip S.E.). 



After spending so many daj^s on the granite terrane, it was 

 a great relief to leave it and to greet again the heavy- colored 

 Ky'6n,g-mng formation with which 1 liad liecome acquainted on 

 my first traverse (pp. 11-37).
