52 BOKARO COAL-FIELD. 



incline gently to tlie south. A little lower down the stream is a bed 

 of coal, two feet six inches. Under^ and also above itj are carbonaceous 

 shales. The dip has increased here, and is as much as 1 5°. One or 

 two other seams occur, but the section is very imperfect, owing to 

 the general occurrence of sand. Just where the nullah joins the 

 Bokaro a large bed of shale crops out. This has also been cut into, 

 under the expectation of getting coal, but excepting in places where 

 little strings of coaly matter occur there is no approach to coal. The 

 dip is north in the Bokaro. 



Three hundred yards east of the Kujree, the Tapin and Mando 



Bokaro section (contd.) ghat occurs. A seam of coal has been cut into 



where the road crosses. The dips are west and west-north-west, at 



angles varying from 10° to 12°. None of the seams have any pretence 



to be called coal seams, but as they contain small strings of pure 



matter, probably they burn sufficiently well for brick-making. After 



an interval the dip is north-west, and there is a basin-shaped depression 



in the beds. A dyke occurs some little way further, crossing the 



Bokaro. Its extension in the direction of Pindra is plain enough, 



but there is no trace of it near Mando. West of the dyke is a 



seam partially injured by trap. The river then runs nearly due 



east, and flows through sandstones, cutting in one place a gorge, 



which, although not deep, is instructive in its way, as exhibiting the 



excavating power of water. The water at the bottom of the gorge is 



very cool and pleasant to drink, and in the hot months, it furnishes the 



most interesting portion of the section. The sandstone in the gorge is a

carbonaceous strings. 

 The dip of this sandstone varies in its direction, being sometimes 

 northerly, at others southerly. In the jungle, however, south of the river 

 the dip is north-east,
