PLATE V. 



Fig. 1. A bird's-eye view ivcsl ivardfi from tlie Hoaiig-tjii-chhi pass, showing 

 before iis liigli ridges l\'iiig parallel to one another and all running 

 nieridionally (p. 30). Tiie one nearest to ns is a granulite ridge, 

 the other behind is built up of eye-gneiss, and is separated from 

 the distant high ridge of l'äik-un-sau (1234 m) by the meridional 

 course of the Som-jiu-gang which flows past tha cumncd of Ha- 

 doug. To the right is seen the paak of Pang-jyang-bong (1942 m), 

 the highest poiut of the Cliiri-sau massive (eye-gneiss), and to the 

 left ill the corner the peculiarly poiated Ök-kul-bong whose 

 geological nature is unknown (p. 39, 42). 



Fig. 2. — The frozen Söm-jin-gang at the turning point of it^^ course in the 

 defile of the Chiri-sm mountains. The large, fissured, scalenohedral 

 block of eye-gneiss in front is popularly called mil-bahol or the 

 ' buckwheat stone ' (p. 43) and serves as a landmark separating 

 the two provinces of Kyöng-sang-Üj and Chyol-la-Do. The high 

 point iu the distance is the already-mentioned l\ing-jyang-bong 

 (fig. 1 above) of the Chiri-sau mass (eye-gneiss). Kai-clii in the 

 middle of the picture is at the fork formed by a tributary. The 

 scenery here is sublime and often sung by Korean poets (p. 42). 

 At another fork behind is Hoa-kai-jyang (p. 43) whence a road 

 leads to the monastery of Ssaug-gyöi-sä. The meridional parallel 

 ridges are cut off equatorially by dislocation at aljout Kai-chi, as 

 may be seen in tlie photograph. See page 42. 



Fig. 3.-— V'iew of a transverse valley of the frozen »Som-jin-gang, as seen 

 Avestwards from a point at tln) upper end of the course in photo 2. 

 above. The topography is here rather open as tlie defile of the 

 Chiri-sau mass is left behind. To the left one sees masses of mount- 

 ains which have slipped down into the gorge from the high peak 

 of I'aik-un-saii l)y e(]uatorinl lines of the dislocaticm Avhicli gave 

 rise to the ]iresent valley.
