The river then turns, and essentially the same section is seen, 



slightly altered, however, by small faultings and the thickening of beds 



of sandstone. No. 10 becomes of better quality, and would be a far 



better seam to work for the coal required in Hazareebagh than the 



wretched ones which are cut into. The contractors, however, have to 



furnish a certain number of maunds for the rupee ; and therefore it is their 



object to obtain the heaviest and most stony coal they can, because the 



required weight will then be contained in a smaller bulk, and the 



expense of procuring and conveying be lessened. 



BoJcaro Section [confd.) — In the Bokaro, north-east of Suroobera, two 

 seams of coal occur dipping to the north ; their section is as follows.
