JOURNEYS THROUGH KOKEA. HI 



Before leaving Kun-san, I must not forget to mention a belt 

 of conglomerate, sandstone, and sliale along the sonthwest shore 

 of the harbonr overlying the above-mentioned metamorphics. 

 Mr. IxouYE saw the rock, and to me it seems to be a continua- 

 tion of the problematic IMesozoic of Nam-pho, already referred to. 



To the east within a few kilometers one can see the hillocks 

 to which we now turn our attention.

Our pathway to Clvj'ôn-jiju led across rice fields, and became 

 slippery during the rain making the journey extremely unpleasant, 

 the reason being that the land is simply a part of the mud flat 

 of the low coast of the Yellow Sea. People go out wearing 

 clumsy wooden clogs and carrying bamboo sticks. Their houses 

 are sheltered by bamboo groves making the scenery resemble 

 that of farming district, at home. During my long wanderings in 

 Korea, I rarely met with clayey soil of such wide extent as 

 here. The soils in the peninsula for the greater part consist of 

 arkose sand if not of gravel. Valleys are generally speaking 

 mere accumulations and heaps of gravel, Alluvial and Diluvial 

 terraces being almost entirely wanting. This is the characteristic 

 land (and also geologic) feature of the peninsula. The agronomist 

 wants more clays for his purpose, though the soils are richer in 

 lime and alkalies than those of Japan. 



After an hour's walk we entered the hills of Im-pliL The im-phi 

 rocks are all eruptive gneisses of various structures, (a) One 

 variety is coarse-schistose with distended eyes of quartz-feldspar 

 mass in black micaceous bands, (b) The other is Lagengnsiss rich 

 in biotite with spots of microclin e or anorthoclase. Micas are 

 of two kinds, the biotite being of the chocolate-brown color and 

 lash- shape. The quartz is crushed to 'grains, showing undula-
