CASTLE NEROCHE. 45 
fortifications. This is a very common arrangement in 
British stations of importance. I imagine the outer 
enclosure to have been intended for cattle ; the second, 
which is more strongly fortified, to have been occupied by 
the neighbouring population, who took refuge in the strong- 
hold in times of danger ; and the smallest and strongest, 
to have been the eitadel. The analogy between this three- 
fold arrangement and that of a mediseval castle is so 
evident, that I trust I may be excused the slight anachro- 
nism of calling them the outer and inner bailies and keep 
of the place. This threefold division prevails at Worle 
Hill, Orchard Castle, near Pen, and, I think, at Hamdon 
Hill; and Iam inclined to believe that, where it is not 
adapted, the nature of the ground rendered it unnecessary 
or inconvenient, as at Cadbury, where there are but two; 
or the fortification was constructed in a hurried manner, 
on some particular emergency, as it appears was the case 
at Dousboroush, the work being probably incomplete 
in its details. The two ramparts facing the southern 
entrance, and slightly overlapping each other, show a 
method of fortification also to be seen in great perfection 
at Worle Hill, where the ground, for a considerable 
distance in front of the strongest part of the place, is 
trenched with several parallel ditches, rendering a direct 
approach to the ramparts almost impossible. The ap- 
proach to the entrance of what I have called the keep, 
running as it- does between two high ramparts, is a good 
specimen of the rude science often to be met with in British 
works. I have not discovered at Neroche any traces of 
flanking out-works, which form. striking features of the 
plans both of Worle and Dolebury ; nor does there appear 
to have been any masonry except the Roman work already
