106 AI^T. 2. — B. KOTO: 



I hastily passed Tong-nai (PI. XXV. fig. 1) and Fusan-chin 

 (PI. XXV. ßg. 2) in the masanite terrane and was again on 

 porphyrite ground in. the Japanese settlement at Fiisan on March 

 19th, 1901, after having spent nearly two months on the 

 traverse (see page 11). 



Df*touks ^^1"- Yabk took the high-road from Ulsan to Tong-nai via 



Keui-jyang '^ on the shore, supplementing my observations made on 

 the country-road tliat runs west of his route. Having started from 

 Ulsan, he went due south on a dissected erosion flat of the " red 

 formation," and near Nam-chhang he came across the overlying 

 green tuffite corresponding to my flinty tufflte. At the Hoa-tlio- 

 mjong'^ elevation on the south of Nam-chhang, a green eruptive 

 ■was seen ; it is an offshoot of the Tai-hoasan ^^ mass, consisting of 

 breccia and sheets of green porphyrite here decomposed into red 

 rock. Then, as far as Keid-jgang he journeyed over a hilly tract 

 of tuffite, sandstone with coaly flecks, and shale with carbona- 

 ceous layers. 



I saw no such complex on my journey, and Mr. Yabe is not 

 able to decide whether the said bed is of young Tertiary or of 

 the Lower Kymgsang formation. On account of its stratigraphie 

 position I shall at present include it in the hlack series (PI. XXXV. 

 Profile AB, No. 2) of the Upper Ky'öngsang formation. At Keui- 

 jyang, porphyrite was seen occurring in isolated outliers on the 

 masanite base down to Tong-nai. 



Mr. Yabe also made a trip from Tong-nai to Kyöng-jyu via 

 Yangsan ^^ and On-yang °^ on tlie route running parallel to, and west
