PLATE VII. 



Tip:. 1. — Tlie equatorial flat of Kang-jiu (|^ ^^), as seen from the east. 

 The northern hill is built of sericite-schist iuterbanded with 

 X3sammitic quartz-schist, both together forming the so-called Kang- 

 jin schist series, striking N. E.— S. W. with the dip N. W. (p. 54). 

 The eumncil lies in a hollow slope of the hill and is enclosed b}- 

 mounds on three sides— a characteristic feature of eumnms in 

 Korea. The plain extends to the left terminating at the head of 

 a deep inlet. Anciently the Quelpartians usually landed here, 

 when this place was called Tam-jin (|j[; '^), in order to pay tribute 

 to the court of the kings of Sil-la in Kyöng-jyu. A king of Sil- 

 la therefore gave the name of Tam-na or the 'land of Tam' to 

 the island of Chyüi-jyu (p, 138). 

 Fig. 2. — A reef of quartz-schist and muscovite-schist of the Kang-jin series, 

 standing almost vertical. It runs south west wards as the prolonga- 

 tion of that already noticed as occurring in Kang-jin (fig. 1 above). 

 Once a copious stream had eroded the reef across its whole 

 breadth in its southward course making a narrow gorge here, and 

 the wind-gap so formed is called Söng-mun-san or tlie ' stone- 

 gate' (p. 55). 

 Fig. o. — The eastern entrance of the well-known whirlpool of Myöug-yang- 

 jin, as seen from Sam-chi-uön (H ^ |%) at the foot of Ok-nuii-san 

 (p. 58). The snow-clad, highly-sculptured hillocks across the sea 

 are the island of Chin-do which is built up of brecciated felsophyre 

 of the Upper Kyöng-sang formation (p. Gl).
