MALLET: COAL-FIELDS OF THE NAGA HILLS. 



Dipj soutli-40''-east at 80°. The lower band of the main seam is of 

 the best hard coal ; the upper is of medium hardness. Lower down stream 

 beds of 2' 0* and 1' 6" are exposed. The 29-feet seam is, perhaps, 300 

 yards above the junction of the two branches of the Wakang, and at an 

 elevation of 670 feet above the plain. 



Some half mile or so above the junction, in the left (southern) 

 branch, there is a section exposed as follows ;— •

Dip of main seam east- 10 "-south at about 30°. The coal is of the 

 best hard kind. Elevation 940 feet. Lower down stream three or four 

 seams are exposed, but none of them are workable. There is also one 

 obscured by a landslip, amongst the debris of which are lumps of good 

 coal. 



"Where the path from Naginimora to Kongan crosses a nalla west 

 of the village, an inferior seam of coal is visible at 

 an elevation of 1,700 feet. 



Kongan path 



In a small stream joining the Dikhu near the boundary of the 

 Neighbourhood of Tel Tipam rocks, two or three seams are visible ; none 

 of them, however, are of workable thickness.
