DKTAILKI) DKSCIMI'TIONS OF THE RESPECTIVE COALFIELDS. 25 
roportcnl tliat witli the exception of a single seam of good coal, 1 foot 
thick, oast of Slicinshanggiri, no coal outcrops had been discovered ; 
although a bed of carbonaceous shale about three feet thick occurs 
and probably represents the principal seam of the Daranggiri field. 
At a later date P. N. Datta ^ added three outcrops to that men- 
tioned by JjaTouche, the tliicl<est Ix'ing IH inches. Dr. King ^ in 
reviewing the known information regarded it as questionable whether 
the field could be worked even were the locality less difficult of 
approach than it is. 
Kalu river. — On the up[)er Kalu, near Chipagiri, there is a small 
shallow basin of Cretaceous rocks, but no trace of coal has been 
observed. 
Kliasia and Juinlia hills. — Coal of both Cretaceous and Tertiary age 
has been long known to exist in these hills. The occurrences in 
a few localities were reported on in considerable detail by Dr. 
Oldham in the first volume of the Memoirs of the Geological Survey 
of India. Ball * mentions the following localities with their eleva- 
tions where coal is known to exist : —
