rampart formed of loose stones, the principal rampart being run 
together with lime, so as to have a solid mass of concrete in the 
centre. This had been produced by mixing the lime-stones with 
- brushwood, which was set on fire, and then when heated, water 
was poured in, or the smouldering mass left open to the rain, and 
then fragments of stone cast in, so as to form by degrees a solid 
mass of concrete, which could not be dug through.* The whole 
was then banked up with earth and stones, and probably a- 
palisade planted on the summit. All this has now been cleared 
away, and we cannot but regret the loss of so interesting a- 
structure. Hardly any trace of it now remains. 
There is no indication of such a method being followed at 
Dolebury ; here the rampart is entirely formed of loose stones piled 
together in rough masonry, after the manner of the Worle Camp. 
The other Camp at Stokesley Slade, on the opposite side of 
Nightingale Valley, has a curving rampart which cuts off an 
angle of the ground, formed entirely of loose stones, and resembles 
that at Dolebury, and there seems to be no trace of lime; this is - 
probably the more ancient Camp of the two. The third, that on 
the Clifton Down, has indications of lime and more regular 
walling, it has also a small inner fortified portion at the angle on 
the north-west side, asis the caseat Dolebury. These Camps pro- 
tected the navigation of the River Avon, and are no doubt of 
different dates. The number of the Archeological Journal for - 
‘September,1880, contains an article on earthworks by a well-known - 
antiquary. He has cited Dolebury as an example of ancient’ 
- British work, but gives it the name of Roborough, which is the name 
of the village on the southern side of the ravine but not of 
‘the Camp. Dolebury and Roborough are separated by the 
deep valley of which I have spoken; an account of Row- 
berrow or Roborough will be found in Collinson’s History 
“ 
* The construction of the rampart resembled the vitrified Forts common in 
Scotland, (For an account ofsome of them see Arch, Journal, vol, xxxvii.
