Doda Rashy Guda, or great heap hill, which contains the mines,
is a peak about three hundred feet in height, and a mile in length,
that forms part of a ridge running nearly north and south, and lying
east from Cadu-caray. Between the mine and this village is another
ridge, on the northern extremity of which is a temple dedicated
to Ranga, and named Mavana Canavay, from which the rivulet so
called has its source.
As I ascended this nearest ridge, the first rock which I met was Strata.
an earthy quartz, or hornstone, divided by fissures in all directions,
and having some of these fissures filled with veins of white quartz.
This rock is not vertical, but dips much toward the east. Further
on, the common rock consists of alternate parallel layers, firmly
united, of white arid quartz, and of brown iron shot quartz, or horn-
stone. These layers are sometimes plain, and at others disposed in
swirls ; and as the stone in decay, by the attrition of its longitudinal
angles, has a great tendency to assume a cylindrical form, and
always breaks in masses truncated at right angles to the layers, it is
often found in pieces which have a strong resemblance to petrified
wood. The stone does not break regularly in the direction of the
layers, which are disposed in the same line with the strata. These
are vertical, and run nearly north and south. I am by no means
sure of the nature of the brown part of this stone. It may very
possibly be hornblende overcharged with iron; and the Sienite found
yesterday nearly in the direction of its strata, strongly confirms this
opinion.
Between the two ridges I came to the channel of a rivulet, named Kemodu,
Aladi-holay, which at present is quite dry. Here 1 found the place
whence the glass-makers procure the ore called Kemodu. For about
three quarters of a mile the bed of the rivulet is filled with stones
of a steel-grey colour. Many of these are the iron ore called
Kemodu. It is in water-worn masses, from the size of a man's head
downwards, and possesses the external characters of the grey ore
of Manganese. When powdered, it is attracted by the magnet
