_ „ ,. . far from the village of Murpipria coal is found 



Further continuation ° r L 



of the sections. again among the upper Damuda beds ; and the 



following section of the rocks containing it will 

 illustrate the general character of the formation. (Descending) 

 Murpipria section. Thick bedded grits. 



A. 10 inches of good pure coal, dip 5° to 15°. S. 30° E. 



B. 3 feet soft sandstone. 



C. 3 feet (a) 6 inches black micaceous shale. 



(b) 2 feet coal. 



(c) 6 inches shaly coal. 



D. 3 feet hard sandstone. 



E. 4 feet fine blue clay, sometimes laminated, sometimes with a 



complicated jointing. 

 The outcrop of these beds is only seen for a few yards along the 

 stream, but before their dip causes them to dis-

above given have all altered in value ; B. has 

 thickened at the expense of C. In one place the coal A. divides, 

 and encloses a long flat lenticular shaped mass of grit similar to that 

 which covers it. The sandstone B. absorbs the top shales of C. alto- 

 gether, and the lower layer of shale of the same section also van- 

 ishes, leaving from 18 to 22 inches of good coal between two bands of 

 sandstone. 



B. and D. are mostly identical in composition, micaceous sandstone ; 

 sometimes soft, sometimes hard, and generally so carbonaceous as to be 

 quite black, often with an obscurely laminated structure. 



Farther on, A. and B. have both vanished, and are replaced by 3 to 4 

 feet of grey, and blue, laminated mudstone, or sandy shale resting on 0. 

 C. itself has expanded a little, but now encloses about 4 inches of shale 

 in its middle.
