AN OROGRAPHIC SKETCH OF KOREA. ;| 



Siniao and the Korean, and moreover, I believe il is the youngest of 

 all the mountain-ranges mel with in the whole of Korea. 



What the real position of this system is in relation to those prevail- 

 ing in Japan and China, f am not able to tell. The western half of 

 Bondo (Japan) seems to have been greately influenced by this system. 

 In the interior of South China it seems to have some connection with 

 the low series of mountains which decides the lower course of the Long 

 River. These low ranges are probahly members neither of the Kuen- 

 lun, nor the Sinian. We lack a detailed knowledge of these low 

 basin-ranges of the Yang-tze-Kiang. 



B. THE KAI-MA LAND 



North Korea, as I have already stated, is divisible into two 

 regions, riz., the plateau of Kai-ma on the north, and the hilly land of 

 Paleo-Chyo-syön on the south. The boundary between the two is 

 sharply marked. The north is a. high plateau with a fault-sear]), facing 

 southwards towards the depressed land, just as the Great Khingan 

 (Hsing-an) turns to the east with its precipice towards Manchuria 

 The incurves of Korea Bay on the west and that of Chyo-syön Bay 

 (Broughton Bay) on the opposite side give some idea, of the boundary 

 as expressed in coast-lines, and we can trace it in the interior as well. 



The natural limit is sa distinctly marked that in L033, Lök- 

 chong", the ninth king of Ko-ryo, ordered his subject Y"u-syo 2) to 

 build a stone-wall, 25 feet high and thick, across the peninsula so as to 

 check the incursions of Niichêns 3) and Chitans 4) from the Manchurian
