Some shales occur, but they are of no great thickness. Faults are 



generally marked by the prevalence of " kunkur" along them. 



Three miles North of Jemeri, and beyond the Grand Trunk Road, 



a' coal seam has recently been discovered by 

 Banali seam. 



boring in the land of the village of Banali, and 



workings upon it have been commenced by Messrs. Erskine and Co. 



The dip is South about 30°, and the thickness of the seam is said to 



be 12 feet. The out-crop crosses the valley lying West of the village 



of Sathgram. This is an instance of what is, doubtless, common, viz. 



a coal seam, the out-crop of which is concealed by alluvium, and which 



can, consequently, only be detected by boring. 



IV. Nunia Valley, East Division. 



This area comprises but few mines of importance, and, owing to the 

 distance of a considerable portion of it from all carriage, whether by 

 river or railway, it has never probably received the attention which 

 has been given to Raniganj and the Singaran valley. It contains,

 on the East by the water-shed of the Nunia and Singaran, that is, the 

 neighborhood of the villages of Taltur, Ntindi, Akalptir, &c, and by 

 the Raniganj area, just described, and on the West by a line drawn

very few sections are seen, the best being South of Puchra, in streams 



running into the central branch of the Nunia. The mass of the rocks 



seen are the usual massive, false-bedded sandstones, white or brownish,
