6 HUGHES: DALTONGANJ COAL-FIELD. 
To indicate, therefore, more precisely the geographical position of 
the field 1 am now describing, I have thought it better to discard the 
title of. Palámaun, and in seeking a fresh name to adopt that of 
* Daltonganj’, from the civil station of Daltonganj, which lies just beyond ۱ 
the southern borders of the field. 
The surface of the country within the limits of the field is an 
undulating plain with no rising ground (consist- 
Pe ae ing of sedimentary rocks) that has any pretension 
to the name of hill. All the inliers of gneiss—and there are several— 
have been planed down, and although bordering the field there are hills 
of the same or nearly of the same lithological character, that rise to a 
height of over 200 and 500 feet and even considerably more above the 
level of the Amanat, still the metamorphic rocks where within the area 
of the field have failed to express a definite physical contour distinct 
from that of the Talchir type. 
The principal drainage channels are the Koel and its affluent the 
Amánat. The latter river enters the field at its 
poate eastern extremity about two miles west of Loharsit, 
and then flows steadily westwards until it joins the Koel five miles north 
of Daltonganj. None of the sections that it exposes in its passage 
through the Talchirs and Damüdás are important 
Amanat. 
either geologically or economically ; and the same 
remark applies to those of the Koel. 
The tributaries of the Amánat are small streams with the exception 
of the Jinjoi which may be further noted, as the only one of its import- 
ant feeders that exhibits coal in its banks. 
The Koel soon after its entrance into the field runs between high 
alluvial banks for about two miles, but when it 
US enters into the area of the Barákars its banks lose 
their conspicuous height.
