Then within a few feet comes the carbonaceous-shale group. 

 Tliese rocks occupy the same position in the series as those enumer- 

 ated in the Hoharoo and the previous section of the Bokaro (p. 45). 

 It is true there is not an exact similarity of thickness in the seams ; but 

 taking the entire section of each^ they resemble each other. 



Suroobera NtiUaJi. — To the east of Suroobera, ^ small nullah 

 falls into the Bokaro, and 30 yards from the mouth is a coal seam 

 (which is lower in the series than No. 1 of the last section).

Then below this the rocks are not fully seen. 



Walking from Suroobera to Seerka, three large seams are seen 

 on the road. The dip is very small, and in many cases horizontal. 



Di/he. — South of Suroobera there is a large dyke. 



Doomtirlera. — This village stands partially upon a burnt seam of 

 coal. The boundary south of it is faulted, and there are numerous 

 granite veins in its vicinity. 



West of Loomurbera. — A seam of coal one foot in thickness occurs in 

 the Bokaro. This seam exhibits an interesting example of parallel 

 faulting. One of the faults is the same as that which cuts off the coal 

 north-west of Bongahara. The remaining sections of coal are very few. 

 None is seen in the tract north of Poreedeeh, between that village and 

 Bokaro. Poreedeeh stands on a burnt seam. 



CJmmargurJia. — North of Bongahara is the Chumargurha ; in it a 

 few seams are visible. One of them of wretched quality is being cut into 

 for supplying Hazareebagh. It is the seam cut off by the fault just 

 referred to. The thickness of the seam is four feet eight inches. The 

 other seams are not worth referring to.
