42 JONES: SOUTHERN COAL-FIELDS OF SATPURA GONDWANA BASIN. 



getting right through the coal, it is impossible to tell at present the 

 actual thickness of the seam, but it may without much chance of 

 exaggeration be considered as at least 8 feet. It would be difficult 

 to test this seam, owing to its unfavourable position up the Tamia 

 river, and to the fact that to the dip, where borings would naturally 

 have to be put down, the eastern bank of the river rises up abruptly in 

 a cliff of some height, and is composed at the bottom of about 

 50 feet of shales, above which sandstone forms a steep slope, so 

 that 100 feet of superincumbent strata would have to be bored 

 through before coming to the level of the coal in the river. Any 

 explorations here should therefore take the form of galleries driven 

 on the coal. 



The dip is to the south-east at about io°, and from what could be 

 seen at the lowest point where the coal is exposed just above the 

 quartz vein, it must have been brought here by a fault with a down- 

 throw to the south. The neighbourhood is also considerably cut up 

 by trap-dykes and quartz veins, which would interfere with the profit- 

 able working of the coal even if other circumstances were favourable. 



XXIII. — In the stream running to the west of the village of Danwa, 



north-west of Omerdo (E. Lon. 78 22') and 



joining the Tawa near that village, at a distance 



of about 1 mile from the village in a straight line, there are some 



strings of coaly matter of no value in the sandstone. 



XXIV.— -In the Baradhar river (E. Lon. 78 20') above Dodramou, 



and half a mile below the point where the small 

 Coal at Dodramou, " . ... 



stream from Bakan comes in, there is a coal seam 



which is possibly the one referred to. by Major Ashburner in 1866 as a 



seam upwards of 2 feet in thickness near Dodramou. At the point 



where the coal is exposed the section is as follows : —
