 tbe sandy Nara-chliyon at the foot of the ' Left Garrison ' (p. 102). 

 The Hat-topped, isolated bntte-Uke hill overlooking tli9 surrounding 

 Alluvium is the ancient fortress of Cheung-song (^ M) where the 

 struggle centred in the closing phase of Hideyoshi's invasion during 

 the years 1592—1598. The fight is usually called the battle of 

 Ul-san (p. 103). The hill is built up of the ' red formation,' a part 

 of an extensive inlier around Ul-sau (|t lÜ). which crops out from 

 beneath the ' black series.'

 cends two successive terraces (in the middle of the figure) of 

 porphyrite gravel within the two meridional ridges of green por- 

 phyrite-breccia of the uppermost Kyöng-sang formation. Terraces 

 are extremely rare in Korea (p. 101).

 granitic Keum-jyöng-san (p. 15) ; it bubbles up from sand near 

 the bank of a dry rivulet. It is a clean bath-resort near the 

 Japanese settlement of Fusan. The high building in the centre 

 is the bath (p. 105). The top of the mountain is the old castle 

 of Keum-jyong on the masanitic laccolith (p. 15).
