189 I'KinrOl? : CKOLOGY AND COAL RESOURCES OF KOREA, C. J*. 
coal at the eastern end of the field, and seam 2 at the west- 
em end. 
It is undesirable to insert in the text of this report the details 
of all the exposures examined, but they have been tabulated 
in Appendix I, where they are arranged according to the attempted 
correlation, horizon by horizon, a serial number being assigned 
to each outcrop, and inserted both in this table, and on the map 
(Plates 30 and 31). The numbers commence at unity in each field. 
The Kurasia field is divided into two sections — Kurasia and Chirmiri 
— and the exposures tabulated separately. In the Sanhat field 
and the Chirmiri section of Kurasia, the exposures are numbered 
in order from east to west. In the Kurasia section the numbering 
is generally from south to north. 
From this table it will be seen that there is an extraordinary 
variation, both in thickness and in the character of the rocks of 
the coal series from point to point. Thus the 86 feet of coal of 
Karar Khoh in the Kaoria Nala (Kurasia, No. 33) is probably 
represented by the 3' 5" seam, thinning to 11 inches, at Dubpani 
(No. 32) in the same nala, only about 1 mile away. Less sudden 
changes are seen at other points of both fields. These changes 
indicate that although one horizon seems to have been widely 
spread yet the conditions of deposition varied widely from point 
to point. 
We are now in a position to deal with each field separately 
from the economic point of view.
