 Glamm, described from Hungary and fServia. At the time of 

 my visit, a few people were doing open work for pros- 

 pecting. ]Mr. ^Iaki, the ow^ner, told me that 4 hn northwards on 

 the river bank in Pcm-]/a-donff^\ there exists an old pit where tlie 

 Koreans once worked f(^r the silver contained in the galena of 

 the granitic rocks. Here 1 may mention that magnetite occurs

From CJihyang-iiön we went half way round Pal-Jijoihj-mu -\ 

 (PI. 11. ////. 3), first going south-eastwards on the masanite terrane, 

 then turning to the west, and at last reaching the hear! of the

 high, are located about 4 km north from the coi^per mine. At the southern foot (^f the mountain 

 lies the ahove-named Taii-ya-domj, and at the northern foot is situated another village, l'mh-tjyùl 

 The district is likewise built up of green porphyrite. In the former village, numerous small 

 ditches or basins where the ores mostly galenic were worked in former times, were arranged in 

 the north-south direction. The dejected ores, still found in the neighborhood, contain generally 

 U.OÜlQOu of silver. In the latter, one finds a quai-t/ vein of ().'2-l.Ü foot thick, extending 

 meridionally over one thousand feet. Numerous old mines are still st-en along the vein.
