doned. Within the area of this camp are several curious 
eircles, difhieult to explain, about twenty or thirty feet in 
diameter, principally towards the western point, but one is 
nearly in the centre, composed of separate stones, surroun- 
ded by a slight shallow excavation or ditch. On the north 
side of the camp there is a subterranean passage from the 
top, through the rock, to the lower part of the hill, which 
is now almost filled up with stones.” 
Since this description was written, the trees with which 
not only the rest of the hill, but unfortunately the area of 
the camp also has been planted, have grown so much, as to 
render it impossible to perceive the plan of the fortifica- 
tions at one view. It appears however to me, to be 
easily made out as far as the mere fortification is concerned, 
though the earth works which exist on the south and west 
sides.of the hill have been so much interfered with, and in 
some parts mutilated, as to present only a maze of inextri- 
cable confusion. There can be no doubt that these ramparts 
were originally not as we now see them, shapeless heaps of 
stones, but dry walls, erected on the sides of the trenches, 
from which their materials were taken, and were probably 
much higher than they are now. This however does not 
apply to the trenches to the east of the main fortification, 
where there is no appearance of walls, and which were 
probably dug to render the level ground on that side difh- 
eult to an invading force, while the stones taken from them 
served to strengthen the fortifications of what I may per- 
haps be allowed to call the keep of the place, which is a 
rectangular space, strongly defended on three sides, imme- 
diately within the eastern rampart, and divided from the 
western part of the fortification by a trench cut in the 
solid limestone. At the south-west angle of this rectangular 
fortification, we find the traces of the main entrance to the
