yöng, the headquarters of Yuk-chin. It then crosses again the river 

 at the north of Kyöng-heung, apparently ending on the south side of 

 Possiet Bay in the Russian dominion. A Russian military station, 

 Savlofka, lies at the foot of the ridge on the north side of the river 

 just opposite Kyong-heung. 



The road from Kyöng-heung to Hoi-ryöng across Yuk-chin goes 

 between the two ridges, and the course of the Tu-man Gang is for a 

 short distance deflected on the south foot of this ridge, corresponding 

 to both arms of the U-shaped outcurve of the Tu-man Gang. 1} 



A glance at the structural lines of the north border of the penin- 

 sula, will lead one to conclude that the above-mentioned ridges con- 

 verge or rather approach each other near the mouth of the Tu-man 

 Gang. Ranges of the Kai-ma Land trend E.N.E., while those of Yuk- 

 chin run nearly due east. I here wish to call particular attention to 

 the fact that the latter are in the Chyang-paik-san direction in contrast- 

 to that of the Liau-tung. 



F. v. Richthofen's geologic map of Liau-tung shows structural 

 lines analogous to those of my field, and both form, indeed, a geologic 

 unit. Moreover, a recent journey of E. v. Cholnoky 2) disclosed an- 

 other ridge with the E. W. trend near San-tao-kou, which, I believe, lies 

 further north of the Chyang-päik-san, apparently with the same struc- 

 ture as in my field, lie says that the geologic line cuts through 

 Tung-hoa-hsien and reappears near Tieh-ling 3) in the complex of phyl- 



1) Tu-man or to-mun signifies ton-thousand in the Xiichen dialect; Tu-man Gang, there- 

 fore, means ten-thousand waters or a stream having innumerable tributaries. I believe the 

 name originated from the feather-like arrangement of its affluents which flow down from the 

 basalt-mesa of Kai-ma in the upper course of the stream.
