horizontal stratification, the beds not being inclined more than from 

 3° to 7°. The direction continues to the South-east. 



In this huge seam there are two sets of workings, both belonging to 

 the East India Coal Company. One a quarry, situated at Dhosul, 

 East of the Singaran, the other a mine at Tapassi, "West of the stream. 

 The former has long been worked upon the extreme out-crop of the 

 coal ; the latter, after being abandoned for many years, was recommenc- 

 ed in 1857 : in the mine, 11 feet, in the middle of the seam, is extracted, 

 leaving 5 or 6 feet above and below. Just "West of the colliery, at 

 Tapassi, is a fault with a down-throw to the West, probably the same 

 as that which throws the coal seam East of Chokidanga. The quarry 

 of Dhosul lies "West of this fault, which is of small extent here. 



The out-crop of the Tapassi seam can be traced for more than half 

 a mile to the East of the Singaran, towards the 



Jorjanki. 



village of Jorjanki. It is marked throughout by 

 pieces of burnt cinder, showing that like many other seams in the district, 

 it has been on fire at the surface. The out-crop lies some distance within 

 the boundary of Dhosul village, but as the dip is small, there can be no 

 doubt that this fine seam underlies the whole of the Western part of the 

 land belonging to the village of Jorjanki, at a depth of not more than 

 150 or 200 feet at the outside. The extent is probably greater than 

 merely a portion of the village lands, but there are so many faults in this 

 part of the country, that nothing is certain, the evidence of which is not 

 seen, and all the country around Jorjanki is covered by laterite. 



The Tapassi seam is probably about 400 or 500 feet above that at 

 Chokidanga The exact depth of the latter below the former cannot 

 be measured, as no continuous section exists between them. 



About a quarter of a mile South of the Tapassi seam, the intervening '
