RANIGANJ COAL FIELD. 



[Chap. IV. § 4. 



Damulia Colliery. 



But West of Raniganj it is different. Beyond the faults bounding 

 the colliery all the Northerly dips disappear, and 

 the rocks come in with a steady South dip 

 averaging about 3° or 4.° South of the Nunia, coal is found underlying 

 the village of Damulia, and, although thrown by several small faults, 

 the seam appears to underlie the greater portion of the alluvium and 

 gravel between the Nunia and the Damuda, on the banks of both 

 of which it crops out in places. Being so close to the surface, the 

 coal is of course inferior and somewhat decomposed. It is, however, 

 worked to a considerable extent, and its section is as follows : —

The quarries are situated just North of the village of Damulia, and 

 North-east of Harabhanga. But the seam has also been worked 

 E. S. E. of Damulia, and is seen South of the village, while it is 

 stated that a pit sunk (by Mr. Jackson) in the bed of the Damuda 

 also proved its existence, so that it probably underlies a considerable
