Chap. IV. § 2.] lower damuda group. 69 



of the Grand Trunk Road, a little East of Bindrabandpur, two seams of 



coal, each about 10 or 12 feet in thickness, crop out separated by 



5 or 6 feet of shale. Two other seams occur between this point and 



the Kudia : of one of these only traces are seen, the other is 4 feet in 



thickness. 



There can be little doubt that very many seams are concealed by 



gravel, clay, and other surface accumulations, 

 South of Nirsha. 



since throughout the West of the field, almost 



wherever sections exist, coal seams are numerous. Of all sections, 



however, none equal those seen South of Nirsha, in the Kudia stream, 



in the quantity of coal. 



The Pasai runs into the Kudia about quarter of a mile South of the 



, „ . bridge on the Grand Trunk Road, over the first- 



In the Pasai stream. 



named stream. In the Pasai a seam of coal, 9 feet 

 thick, is seen, the lowest in the following section. Down the Kudia, from 

 the junction of the two streams, but few seams are met with, and these of 

 inferior quality, and thin. Two, of 2 and 3 feet in thickness respect- 

 ively, crop out some distance down the stream, and at Sangamahal 

 the seam formerly worked there is seen. It is 5^ feet thick, and the 

 quality was, by Mr. Williams, stated to be inferior and similar to that 

 at Barmuri. About this the beds are turned up by the fault forming 

 the South-west boundary of the field, and dip North. 



Proceeding in the other direction, from the Pasai, i. e. to the West- 

 ward and up the Kudia, a magnificent section of the Lower Damuda 

 beds is seen dipping at about 15° or 20° to the South-west. 



The highest measurable section is seen at the first bend of the 



stream below Pitakari, thence in descending order the following beds 



are seen : —
