 a depression of eye-gneiss at the eastern foot of the Plial-hyöng- 

 chhi pass (cfr. PI. XV. fig. 3). It is a type of small eumnais 

 Avliich are comparatively clean (p. 82).

 hornblende-gneiss on the east bank of the Nam-gang which Hows 

 southwards past Chin-jyu (p. 33, PL III. fig. 3). It is in an 

 iutermontane flat in a very fine scenic situation ; hence the name 

 ' mountain-clean,' The photo is taken from the north toward the 

 open south. Here instead of following the river down-stream, 

 I climbed the pass, fig. 3. 



Pig. 3.— The Chhyöng-möri-chhi pass (f^ ]g |lr^-), built up of orthogneiss 

 (p. 81). From the pass (oGO v/i) a view can be had, toward the 

 icest, of tha inner Chiri-san whose low neck (in the right corner) 

 we had passed over two days previously. It is the Pal-hyoug- 

 chhi pass (PL XV. fig. 2, p. 81). San-chhyöug is at the foot in 

 a depression. The whole terrane in view is entirely composed of 

 eye-gneiss or its allies. Page 85.
