by General Pitt Rivers, who is author of the annexed plan. A deep ditch and a 

 high rampart encircle the Beacon Hill. The outer rampart is 6,800 feet, or 1 mile 

 500 yards in circumference ; the greatest length from north to south is 933 yards. 

 The whole camp is'said to contain 44 acres. 



The highest portion of the hill is 1,390 feet,* and forms what may be termed 

 the citadel of the camp. 



The natural shape of the top of the hill was probably conical, and has been 

 made to assume its present form by the high rampart which has been thrown up 

 round it. It is surrounded by a ditch about seven feet deep, and broad enough 

 for a chariot to be driven round it. Formerly there was but one regular outlet 

 from the citadel, and that was situated upon the south side, leading by a causeway 

 into the camp. There is now another entrance from the north-east side, but it is 

 probably of modem construction, made for the convenience for travellers, and for 

 cattle. The outer ditch varies in depth from 12 to 18 feet, and the top of the 

 rampart is from 30 to 40 feet in width. Following the ditch on the western side 

 of the hill, we come upon the principal road or trackway from the camp, trending 

 in a south-westerly direction down to the old road, called the Silurian Pass by 

 Phillips. The next way out of the camp is in the south-east corner, which leads 

 down by a zigzag path to the Earl's Dyke, past the Thorn Tree (a well-known land- 

 mark on these hills). On the eastern side, below the walls of the citadel, is another 

 outlet, leading through a natural hollow in the hill-side, which is much in the 

 shape of an amphitheatre, at which point man probably aided nature for the 

 purpose of forming a place of assembly. 



There are a great many depressions on the surface of the whole camp, which 

 were probably hut hollows. 



I am of opinion that the portion of the camp occupying the northern spur of 

 the hill, just above the British Gamp here, was fortifted by a ditch and rampart at 

 a subsequent period to the formation of the main camp, probably thrown up for 

 the purpose of strengthening it. On the western side of this, are three sallyports 

 leading down to a well at the foot of the hill. 



Upon the flat surface at the base of the western slope of the Beacon, is an 

 earthwork of peculiar form : its measurements I have not yet taken ; but it is 

 surrounded by a rampart — close by it, in fact passing through a portion of it, is an 

 old trackway leading up to the camp, joining the main road leading from the 

 camp at the western side, trending south-west and joining the old Silurian Pass of 

 Phillips. 



Upon the east side of the citadel, and just outside the ditch, is an outwork, 

 thrown up for the purpose of commanding the eastern slope, which the eastern 

 rampart does not effectually do. 



On 11th September, in the presence of Mr. Piper and several local archaeolo- 

 gists, several hut hollows or pits were opened in the citadel of this camp. The 



* Phillips places it at i,ii8 feet.
