which it occurs it does not appear except at this one spot, so 
that its lateral extension is probably limited. Mr. Mallet believed 
that the cost of raising it would be so high that it would probably 
not find a market for local purposes at A yab. The following

Clieduba Island. — Mr. Mallet (loc. cit.) describes a seam seen 
in a stream which descends from a hill north-east of Pallang Eao. 
It is only two feet six inches thick and dips to east-20°-south 
at an angle of 40°. It is similar in appearance to the coal at 
Tsetama. A carbonaceous sandstone was described by Captain 
Halstead^ as occurring less than a mile from the beach to the 
south of Pagoda Hill. 
Sandoway. — On the mainland of Arakan, in the neighbourhood 
of Sandoway, thin carbonaceous deposits have from time to time 
been discovered and samples of lignite from the Arakan Hill Tracts 
have been forwarded, but at present there are no solid grounds 
for believing that a deposit of value exists in these regions. 
Yenangyaung. — In an account of a visit to the petroleum wells 
at Rainanhong (Yenangyaung) published in 1797, Captain Hiram 
Cox 2 mentions that coal is found in the wells at a depth of 
130 cubits from the surface. Subsequent writers have referred 
to the same fact. Its distribution appears to be sporadic, but, 
it appears to be connected with the occurrence of the oil. From 
an analysis made in the Geological Survey laboratory the fuel 
must be a lignite of moderate quality. Similar strings of coal 
have been met with in the Yenangyat oilfield.^ None of the 
occurrences, however, are of any economic importance.
