The subordinate layers, it will be seen, vary rapidly in thickness. 

 The top coal {Jc) in the second section is firmer than the corresponding 

 band in the first. 



Coal was also found by Mr. Greig" in a nalla flowing from Daohal 

 hill. When I saw the outcrop, which was only 

 partially cleared, one foot of coal was visible, 

 dipping east-20°-south at 30°. It appears that Major Hannay 

 opened a quarry in 1847 on the north bank of the Dihing,* but no 

 outcrop is now visible. The seam is very likely the same as that which 

 has been worked close to the south bank. 



A quarry in the latter, belonging to the Assam Tea Company, 

 was open in 1865. Mr. Medlicott describes the 

 seam as 17 feet thick, of which about 10 feet 



seemed good clear coal, but greatly crushed. The dip was very high, 



and the outcrop about 100 feet above the river. f
