porpliyrite. Wliat impressed me at Nàing-djy'àng and its neigli- 

 borhood was the cleanliness of the villagers and their dwellings 

 as compared witli the habitual filthiness of other Koreans ; and 

 the four- cornered straw roofs instead of the round thatches of 

 other Tillages reminded me vividly of rural scenes in Japan. 



From here our way led up the low Xaimj-djijong-hofjai, of the 

 same green rock ^^ and down to tlie talus slope of Koan-Ji/anrj-tho ''\ 

 wliich opens northwards towards tlie Nak-tong liver. The Nämq- 

 àjyïmg ridge runs meridionally, covered with a thin pine forest, 

 and its northern end disappears undei- tlie talus Hat, exposing a 

 highly sculptured, l)uff- coloured slope characteristic of a, graniti(! 

 rock. To the south we see the equatorial, granitic Xa-rim-scm 

 (734 }n) ■"\ capped with a greenish breccia, dipping slightly east- 

 wards ; while to the west lies the meridional, granitic Yong-niol- 

 fia7i ^\ The capping green effusives, however, dipping westwards, 

 expose a very precipitous wall. AVe crossed the neck of Yovg- 

 mot-san, named Iseul-cltîd''^, lùO ui high, strategically an important 

 point between Fusan and Ma-san-plio, and once the battle-ground 

 of the army-corps in Hideyoshi's second invasion. 



On tlic way from Koan-Jgang-t/iô to the above-named pass, 

 we walked about five kilometers over a gravelly talus-slope to 

 the foot of the ascejit where we met with a peculiar rock which 

 also characterizes the basement of the neighboring region. 



The rock is of a light Msli-coloi' with au appearance resembling in 

 one res]^ect a fine granite and in another a quartz-porphyr}'. On the 

 weathered snrface it is not nnlike a pumice in color and structure : 



1) A si)ecimen collectetl by Mr. Inouyé shows a very interesting feature. It is a breccia 

 of augite-porplayrite enclosing fragments of felsoi)hyre with corroded quartz. It is a greenish 

 fnsion-breccia or friction-breccia of iiorphyrite-mass. Here also we haye an examiile of quartz- 

 porphyry and iiorphyrite coming tc>gether. See untf>, page 18.
