northwesterly dip. The boundary of the two orthogneisses was 

 distinctly visible. Seen from the top, the region lying to the 

 west of the Kamnam-clihi pass presents a rough mountainous 

 aspect, because of the oblique trend of the mountain-axis, termi- 

 nating in the headland of Chßn-goan-scm (721 m)^^', just as is 

 the case of the ridge near Nak-an, already mentioned, with the 

 corresponding peninsula of Heung-yang, tliough the trend of the 

 latter approaches a meridional direction. 



From Chin-jyu hither, the country is thinly populated and 

 covered with a meagre growth of pine trees, and it is refreshing 

 to see the real forest on the descent to Chyang-noro-moh'^. 



At the westerly continuation of tlie little gravelly valley, we 

 saw at a distance the rugged height of Sui-in-san^^ with its per- 

 pendicular cliff of romantic aspect, at whose western foot on a 

 small intermontane flat is situated, as tlie people told us, the 

 Korean military station, Py'ông-y'éng*\ It is unusual to find such 

 volcanic topography in southern Korea, and my supposition was 

 substantiated by finding young volcanics at Chyang-heimg ^\ 



Our road now turned soutli to two little passes, Phung- 

 chhl '■'\ of mylonitized gneiss, which here cross the equatorial ridge 

 whose north foot we had followed. On the top we found the 

 Camellia japonica which we liad not seen before in Korea. We 

 saw to the east and south-east Chyoi-oang-san '\ Sä-chä-san ^\ and 

 the rocky soutli ridge of the Kamnam-chhi, capped with the fissile 

 mylonitized orthogneiss upon a base of small eye-gneiss, dipping 

 northwestwards at low angles. These capped outliers attracted 

 our attention by their butte-like escarpments which were fully 

 exposed. The isolated flat tops evidently once formed a shell
