 U()l (once a battle ground) imperceptibly to the Phal-hyöng-chhi 

 pass (A 51 l'i-ÎO which forms the eastern edge of the Un-bong flat 

 and the rim of the axial ridge of the Ciiiri-san range, serving at 

 the same time as the l)oundary between Kyöng-sang-Do and 

 Ohyol-la-Do. One sees in tlie picture three Korean ponies, two 

 of tliem carrying the author's luggage. 



Fig. n. — From tlie top of the same pass a panoramic view opens disclosing 

 the low, dark coulisse ridges (the distant parallel hills are un- 

 fortunately not seen) of Kyüng-sang-Do, which are of the Kyöng- 

 sang formation. The road descends to Ham-yang which lies at 

 tlie eastern foot of the pass (cfr. PI. XVT. fig. 1). The pass is 

 still built up of schistose granite traversed abundantly by aplite.
