86 RANIGANJ COAL FIELD. [CHAP. IY. § 4. 



The next mine to the South, Mangalpur, is one of the most import- 

 ant in the district. It lies about a mile due 

 South of Parasia, and is the property of Messrs. 

 Erskine and Co. It is worked by means of both shafts and quarries 

 upon a seam of coal, of which the following is the section: — 



White sandstone, felspathic, over 100 feet. Ft. in. 



a. Inferior coal and shale 



b. Good coal 



c. Shale 



d. Coal ... ... .... 



e. Shale 

 /. Coal, good 

 g. Shale 

 h. Coal 

 i. Shale 



j. Coal 

 Shale. 



Total thickness of seam 



Coal in ditto 



Or in places 24 feet. 



The clip is North-east, about 7°. Just East of the Singaran, and 

 South of the village of Sonachora, the coal is cut off by a fault, the 

 direction of the throw of which has not been ascertained. A large 

 trap dyke, about 6 feet in breadth, runs through the colliery from 

 W. N. W. to E. S. E., and to the South of this the coal is nearly 

 exhausted on the West side of the Singaran. Pits have now been 

 sunk, and the mine is being worked North of the dyke. 



The backs at Mangalpur strike East 40° North and West 30° North. 

 The out-crop of the coal is marked by a series of quarries, many of them 

 abandoned, which run for some distance up the little valley between 

 the rise on which the colliery is situated, and that upon which, about 

 half a mile South, is the village of Mangalpur. After running North- 

 west for some distance, the line of out-crop turns North over the ridge ; 

 and, if continuous, might be expected precisely where coal is found in
