22 BOKAKO COAL-FIELD. 



The dip reverts to the south, and No. 8 h again visible, and the 

 full thickness of No. 9 is expcsed, namely, 36 feet. (In the first place 

 whore seen, some of the rock is denuded.) Then a small slip takes 

 place, and south of that come —

This is one of the largest seams occurring in the field, and is 

 continuous with the one south of the village of Korgullee. The quality 

 of the coal in this section is better than in the former ones ; and it is 

 occasionally, though not often, used by the villagers. 



This portion of the field, now for the first time described, is the 

 richest in the Bokaro area, and would be well worth the trouble of 

 opening up. The roads, it is true, are not very good, but one 

 could easily, be made, which, after crossing the hills to the north of the 

 field, would emerge on the plain that slopes gradually from Hazaree- 

 bagh to Raneegunj. The quality of the coal is in many instances 

 good, and, I believe, would be found still better, if more opportunity 

 existed for testing it. It would be scarcely fair to consider the top- 

 weathered coals average specimens, as such cannot be the case owing 

 to the concentration of inorganic matter, and the deposition of extrane- 

 ous impurities from water. 



West of the Godo the geological structure of the country is not 

 well seen. The dip along the northern boundary is pretty steady both 

 in amount and direction, varying from 7° to 10° and from south-east to 

 south by east. 



Near Gobinpoor a cross fault shifts the northern boundary. The 

 evidence of a displacement is complete, and excellent confirmation is 

 afforded by a line of springs breaking out at the junction of the gneiss 

 and Barakars. Our attention ought always to be du-ected to the dis- 

 covery of springs, and suspicions raised as soon as they are met with, 

 as they often indicate a break in the rocks.
