the Bansra and Parasia shafts. But until the coal in these shafts is 

 cut through, and the section fairly exposed, it is impossible to ascer- 

 tain, in the presence of the numerous faults which unquestionably 

 exist in the neighborhood, whether the seams are identical or not. If 

 they are, and, as is in that case probable, the burnt out-crop already 

 referred to as occurring in the Singaran, North-west of Parasia, 

 belong to the same seam, the coal must underlie a basin of considerable 

 size. The dips alone would favor this view. 



Whether the Mangalpur seam be identical with that worked at 

 Parasia or not, there can be little doubt about 

 its being the same as that worked at Harisptir 

 and Babusol, both mines belonging to the Bengal Coal Company. The 

 first-named lies about 2 miles South-east of Mangalpur mine, the latter 

 rather more than a mile South of the former. At Harisptir the 

 section is : —

The dip is doubtful, the workings not having extended far, and the 

 bed being nearly horizontal, or slightly undulating. Coal has been
