THE TAWA FIELD.

The base of the coal is concealed by a pool of water, so the 

 seam is probably somewhat thicker. A few yards lower down the 

 stream, a bed of sandstone appears in the sandy shale layer, and rapidly 

 thickens out to the exclusion of the shale. The other beds are also 

 very variable in character within short distances, and the mass of 

 sandstone at the top appears to rest unconformably on a denuded 

 surface, as the junction is very irregular, in fact it appears as though 

 this would prove to be nothing more than a large pocket of coal. 



XXV. — To the south-east of the deserted villages of Bhogi-Khapa 

 Small seam near Bhogi- ( E - Lon - 7 8Cl 3') on the right bank of the Tawa 

 Khapa# river, at a distance of about half a mile below 



the Talchir-Barakar boundary, a two-feet seam of coal is exposed 

 under an overhanging mass of sandstone. The coal rests immediately 

 on massive sandstone and is covered by sandstone of the same charac- 

 ter. The dip is to north-west at 5 . 



In a small dry watercourse to the south of the Tawa, between the 

 river and a little hill to the south, close by the last exposure, the same 

 seam is again exposed. It is here of poor quality and only 1 foot 

 is seen, as it is situated in a small hollow in the bed of the stream 

 which is much blocked up with large boulders from the hill. The dip 

 at this point is to south-2o°-west at 20 . This is probably the 

 Bamanwara-Khapa seam of Major Ashburner's report 



XXVI. — A seam of coal (E. Lon. 78 14' 15") was discovered by 

 Large seam near Pa- Ma J or Ashburner and reported on by him in 

 takhera - 1867 as the Mohodongri seam, but as it is 



nearer to the villages of Patakhera and Sarni I have given them the 

 preference. The coal appears in the small stream which runs past 

 Patakhera, though the village at the time of my visit had been moved 

 some distance to the north-east of the spot marked on the map. This 

 stream runs into the Tawa at the corner where it turns north after 

 flowing to the west past Silwani. 



Going up this stream from its confluence with the river nothing is 

 at first seen but Talchir shales, these gradually pass into sandstone
