\on Cholnoky shows that the Liau peninsula and bay, as 
well as the western shore of th^ Yellow sea. are bordered by 
great normal faults which not only follow the shores, but ex- 
tend far back into the interior. The line already referred to 
which borders the high plateau of southern Manchuria contin- 
ues southward to form the western shore of the Liau peninsula, 
and crossing the straits of Chili meets the western boundary 
of the Shantung in China. Where this line of faulting meets 
the similar lines to the west and east, in one case in the vicinity 
of Kirin. and in the other on the western border of Shantung, 
recent volcanic material is found. The eastern one of the ser- 
ies follows the course of the Yalu river. We may here trans- 
late to advantage the summary by von Cholnoky referring also 
to his map which is reproduced in Fig. 2.

Dotted and dashed lines represent faults, full lines show mountain ranges. 
"While I am about to present a somewhat clear picture of the struc- 
ture of the first mentioned district — making my observations supple- 
mentary- to the studies of Richthofen upon the Liau peninsula — our 
knowledge of the latter, the nortlnvest district, is still so fragmentary
