DISCOVERY OF COAIi. 
degree of heat, more than that of common charcoal apparently, 
and without much smell of sulphur. It bums with a slight whit¬ 
ish flame, being in this particular unlike an Anthracite. It leaves 
a rather earthy cinder or coke containing iron, an oxide I sup¬ 
pose. From the external aspect of this coal I should be in¬ 
clined to think, that it may have been taken from the upper 
Stratum or covering of either the Kamuning or Trang coal.

This is a coal with a dull fracture and slightly glimmering. 
The man who brought it has gone to sea, but I hope on his 
return to be informed of the locality, which I could not discover, 
as he sent, and did not bring, the specimen. But I have little 
doubt of its having been got in the vicinity of Trang, Tama or 
Gurbie. This coal has not a very promising external aspect, having 
a very anthracitic appearance. It nevertheless contains much in¬ 
flammable matter. But bituminous matter does not ooze or bub¬ 
ble out of it during combustion as in No. 2.

This is from Tama coal deposit first called the Gurbie coal de¬ 
posit, because lying in a district of that name, beyond or north 
of Trimg. It was first visited by Captain Congalton in the Ilooghly 
by order of the Ilon’ble the Governor. 
The present specimens were taken by myself from the stratum 
on the second trip of the Steamer to fama. Externally this coal 
looks a good deal like charcoal, but it has a duller colour. It 
is rather too compact for a brown coal or lignite. Its fracture 
is also more conchoidal than the generality of lignites. Its dull dark 
or black colour might cause it to he taken for an anthracite. But 
when exposed to the heat of a charcoal fire with Chinese bellows, 
it ignited slowly, and consumed with a whitish flame, leaving a 
good deal of earthy coke. It appears to contain a good deal of 
inflammable matter, for it continued for some time to give out 
flame after being removed from the fire.
