MALLET : COAL-FIELDS OP THE NAGA HILLS.

 Dip, east-25°-south at 40°. The coal, as well as the associated 

 shales, contains some pyrites. This is, doubtless, the seam which was

 south-west of the above, in a different seam. 



On the path from Jaipur to Hukanjuri, about two miles south-east 

 of the former place, a seam 9 feet thick is ex- 

 posed. It had been partly cut through by Mr. 

 Greig in December 1874, exhibiting the following section: —
