It now seems desirable to assif^n a separate name to that por- 
tion of the Sohagpur field lyinj^ within Korea State, and, for such 
a purpose, no name seems more suitable tlian that of Sanhul, 
the former capital of the State, situated upon this field. In this 
paper I shall, therefore, refer to this eastward extension of the 
Sohao;pur coalfield as the Sanhat coalfield. 
In tlieir survey of this State carried out in the early eighties, 
Messrs. Hughes and Hira Lai examined all the important streams 
traversing the northern or Sanhat coalfield, with the resultant 
discovery of numerous outcrops, the positions

of which are marked on the map or the coalfields 
of the Rewah Gondwana basin accompanying Hughes' memoir. 
The positions of these outcrops are also given in the Appendix 
of Coal Sites on pp. 236-245 of the same memoir. The Korean 
localities are repeated in Appendix II of the present paper. With 
reference to this work Hughes says (p. 201) : — 
' To obtain a standard section my colleague and myself ascended most 
of the streams, large and little, which, curiously enough, have theii- watershed 
nearly coincident with the upper limit of the productive measures, but there 
was in each instance too much incompleteness in the sequence of the rocks 
to secure this result.' 
From this it is evident that Hughes and Hira Lai were unable 
to correlate the seams exposed in various streams ; and, as the time 
at my disposal permitted me to visit only a small proportion 
of the exposures, I must confess myself equally unable to correlate 
with any certainty the coal outcrops of the Sanhat field. 
My visit must, therefore, be regarded as a recoimaissance for the 
purpose of ascertaining whether or no the outcrops indicate the 
possible existence of seams of coal of sufficient thickness and high 
enough quality to be workable. Nothing except boring operations 
aided by the most careful examination of every minute nala will 
enable this correlation to be successfully efTected. Nevertheless, 
as a possible help to future works, I have ventured to put forward 
a tentative correlation (see Table 6, page 190, and Appendix No. I). 
In the Kurasia field, on the other hand, Hughes and Hira 
Lai were able to make only a most cursory examination. Conse-
