THE THIRD TRAVERSE 



Plates XXVL— XXXIII. 



My third traverse crossed the space between Fusan, frequently 

 mentioned above, and Kun-san hj ih.^ Yak-sim-nyöng^^ pass at the 

 Do boundary. I shall however commence my itinerary of observa- 

 tion at Kun-san for the simple reason tliat I so made the 

 journey. 



Kun-san (PI. XXVI. fig. 2 and 3), like Moh-pho, is a free treaty 

 port opened in 1898. Rice and beans are the chief staples of 

 tlie country. The town is located at the moutli (PI. XKVI.fig. 1) 

 of the Keum-gang. '' This river drains the area between the Chhija- 

 rij'ông and the No-ryöng ranges "^^ and waters the largest plain in 

 South Korea, — the rice -producing flat of Chyön-Jyu, hollowed out 

 in a granitic terrane. The port itself is on the south bank 

 sheltered {fig. 3) by hillocks from the west winds. 



The lowest bed is composed of (1) a pliylUtic ser leite- schist (PI. 

 XXXIV. FCx, Ph) with the strike N. 30'' E., and the dip vertical 

 or slightly west. This is overlaid, as is clearly seen at the land- 

 ing place, by (2) a bluish, compact rock of the appearance of 

 ampliibole schist, or cornul)ianite with a slight tinge of violet. 

 Seen under the microscope it consists of grains of quartz, and 

 lobes and irregular lamellae of chocolate- brown biotite, aggregated 

 in such a manner as to produce the hornfels structure. Slides
