d, and so pure when reduced as to resemble
silver. The rough ore produces from _thirty_ to _seventy-five_ per
cent., and on an average fully _fifty_. The iron wrought from it
requires no puddling, and, converted into steel, it cuts like a diamond.
The metal could be laid down in Colombo at L6 per ton, even supposing
the ore to be brought thither for smelting, and prepared with English
coal; but _anthracite_ being found upon the spot, it could be used in
the proportion of three to one of the British coal; and the cost
correspondingly reduced."

following:--
"_Extract from a letter from Colombo, dated 26th Oct. 1798_.
"A discovery has been lately made here of a very rich mine of
_quicksilver,_ about six miles from this place. The appearances are very
promising, for a handful of the earth on the surface will, by being
washed, produce the value of a rupee. A guard is set over it, and
accounts sent express to the Madras Government."--P. 53. See also

JOINVILLE, in a MS, essay on _The Geology of Ceylon_, now in the library
of the East India Company, says that near Trincomalie there is "un sable
noir, compose de detriments de trappe et de cristaux de fer, _dans
lequel on trouve par le lavage beaucoup de mercure_."]
Remains of ancient furnaces are met with in all directions precisely
similar to those still in use amongst the natives. The Singhalese obtain
the ore they require without the trouble of mining; seeking a spot where
the soil has been loosened by the latest rains, they break off a
sufficient quantity, which, in less than three hours, they convert into
iron by the simplest possible means. None of their furnaces are capable
of smelting more than twenty pounds of ore, and yet this quantity yields
from seven to ten pounds of good metal.
The _anthracite_ alluded to by Dr. Gygax is found in the southern range
of hills near Nambepane, in close proximity to rich veins of _plumbago_,
which are largely worked in the same district, and the quantity of the
latter annually exported from Ceylon exceeds a thousand tons.
_Molybdena_ is found in profusion dispersed through many rocks in
Saffragam, and it occurs in the alluvium in grey scales, so nearly
resembling plumbago as to be commonly mistaken for it. _Kaolin_, called
by the natives _Kirimattie_, appears at Neuera-ellia at Hewahette,
Kaduganawa, and in many of the higher range
