yards in diameter, has been raised into a convex form ; the pavement, that 

 covers it, consisting of tabular plates of slaty sandstone, broken into small 

 masses; and the fractured lines generally radiating, though in an irregular 

 manner, from a centre. In some places the tops of these little globular eleva- 

 tions have been removed, leaving a regular circle of stones, whose bounding 

 lines are disposed like the stones of an arch. In other instances they assume a 

 more conical shape, resembling small hillocks, from the upper part of which the 

 outer coating or tabular masses have generally fallen away. When they are 

 of a larger character, the whole presents a heap of broken masses of rock. 



Denodur Hill, an extinct Volcano. — Of the detached hills, the elevation of 

 which I conceive to be due to volcanic influence, the principal is that called 

 Denodur, and is situated near the shores of the Runn. It is the largest and 

 highest hill in the country, and is evidently the remains of an extinct volcano, 

 an irregular crater being still visible. In the north side is a large gaj), reach- 

 ing nearly to the foot of the hill, but partially blocked up by a lower ridge, or a 

 kind of traverse. Its western flanks are composed of a series of ridges of lami- 

 nated clay and loam, interspersed with flat, angular fragments of slaty sand- 

 stone and slate-clay. The surface of some of these ridges is smooth, consisting 

 either of thin slabs of slate-clay, or of thicker slabs of a very compact, crystal- 

 line, and slightly calcareous stone, the same as that which overlies the laminated 

 series, and forms the wafls on the Runn, &c. Near the base of the hill and for 

 more than two-thirds up its side the construction alters, being composed partly 

 of a loose sandstone, and partly of the calcareous grit, containing imbedded, 

 angular fragments of basalt ; the uppermost part is a perpendicular wall of 

 basalt, which, apparently, continues all round the top. A stream of very 

 compact basalt runs past its north-western flank, and in other places. Nu- 

 merous small conical hills, composed of horizontal layers of limestone grit, 

 or of basalt, are scattered over its sides, and its base is covered with a thick 

 mould, formed of decayed vegetables, with earthy matter. Nowhere did I 

 find any traces of recent disturbance, although the people of the neighbour- 

 hood, particularly the Jogees, or religious devotees, who inhabit a temple on 

 its northern flank, asserted that fire issued from it during the earthquake of 

 1819. If it did, there would, of course, be some signs of it remaining; but 

 I was unable to penetrate into the interior of the hill, owing to the dense 

 Bauble Jungle, or crooked thorn tree with which it is covered. 



Not far from this place, and adjoining the village of Nuckutrana, is a hill 

 of some size, called Ungia-soorud, the elevation of which has also been 

 effected by volcanic agency. The flanks and base are composed of a very 

 loose, friable, calcareous sandstone and grit, apparently stratified, but inclined
