stretching direction, Avliile at l^ith-l-n-chjontj '' its axis is equatori- 

 al. At 2 Im sontli of Oa-deun<i''\ the giant-gneiss-porpliyry 

 (the Hadong gneiss) disappears and is replaced by tlie psammitic 

 paragneiss of Kam-halioi (the strike E. 20" N., tlie dip 30 S.) : but 

 this is only for a short distance, and the woody orthogneiss soon 

 crops out again and continues down to Sun-cJn/ön. 



On our detour hither from Ku-nßi, the basement was a com- 

 plex of Ortho- and jiara-gneiss whose mutual relations could not be 

 made out. The complex was overlaid by a sheet of the Upper 

 Ki/öng-sdUf/ formation which described a trough at Clum-su 

 and an air-saddle at Kol-nnm-j yamj with the axis (W.8.W. — E. 

 N.E.) of the CJiin-Ji/u ridge. The Sol-rJihl ridge is the uplifted edge 

 whose south side was dropped down to the gneiss terrane which 

 has the equatorial axis. Looked at from the south (PI. A^L fig. 

 3), the Sol-chhl ridge was seen for a long distance in sharp es- 

 carpment, corresponding to the basset of the green sheet upon a 

 foundation of gneisses. In passing, it should here be remarked 

 that tlie top of Kiihi-su-hong''\ lying to the south-west of Oa- 

 deung was seen capped with a detached mass of green tnff. 



SuN-cHYöx Snn-cJiijön is an important walled eumnCd on the south coast, 



being a landing place and the starting point of the meridional 

 highway of Chyöl -la-Do, which passes through Ku-ri/öl, Nam-uön 

 and Chym-jiju. Ifc is also a place of some importance on the 

 coast road to the west, which we followed. Here General Konishi 

 landed his men during Taikô's invasion of Korea. The country 

 around the town consists of liald, degraded gneiss hills. 



After passing over the south-western hill-neck we followed
