26 AET. 2.— B. KOTO : 



in a south-southwesterly direction for a distance of 13 kilometers. 

 The western mountain-cliff (759 m) is as usual built up of the 

 dual formation of saccha.roidal masanite covered with the breccia 

 and tuff of a green eruptive. From the south end of the foreign 

 settlement (PL II. ftg. 3), U'ôl-r/)jong-dong^\ we ascended a hill pass 

 of Pam-chhl (masanite), the top of which is, however, covered by 

 a whitish earthy quartz-porphyry (eutectophyre), cleaving into im- 

 perfect tablets. The same whitish rock extends down eastwards 

 to the inlet of Pam-lm-ml '\ the much talked of Kussian naval station. 



In coming down to the poor chi/iunak of So-mori ''\ whence the 

 ascent begins to the rather high pass (347 m) of 7^ong-cJii/'ôn-cJihi*\ 

 the quartz-porphyry is again covered and replaced by a green 

 compact rock which is visible from the south foot of the pass in 

 the village of Tong-clujdn. Here I saw gravels of a gray porpliy- 

 rite, a red sandy shale, and a bluish -gray compact ßinty rock, the 

 last being visible as far as Chin-hai. The third rock is seen to 

 consist of splinters of quartz, feldspar and biotite, cemented by 

 very fine polarizing minerals with biotite and coaly matter. It is 

 a volcanic dust, sorted and deposited under the sea, mixed with 

 silt, and the whole is metamorphosed into a compact rock by the 

 intrusion of the laccolite. 



In our journey hitherto we had gone over the geologically 



feet thick, near the contact with the solid ground underneath. I conjecture that the concentration 

 of gold dust at the bottom is probably due to gravity and the rearrangement of the gravel and 

 sand. Inouye did not notice the rich coating on ijebbles in the basal bed. The worldng of the 

 mines of the Yong-dam region are at present in a state of decline, due partly to the exhaustion 

 of the natural resources and partly to the scarcity of water. (^| vH ^ ^ [g.)

3) '4^ 5M [' ^^ ox-head ') This is a commonplace name in Korea. The name of the 

 well-known Japanese god Snsano-o or Gozu-tennö (the ox-head god, who is said to have crossed 

 the Sea of Japan to the province of Izumo), is, according to our historians, a corruption of the 

 word soraUrl.
