360 Yards each. Thefe arc its Dimenfions without- 
iide the Rampart and Ditch ; but within-fide the 
faid Ditch and Rampart the Length is 392 Yards, 
and the Breadth 264. I meafured the Breadth of 
theFofle and Rampart, which I found in fome Places, 
where it remains moll perfect, to be 48 Yards, tho' 
in others not above 3c. And according to my 
Computation the whole Ground taken up, including 
the Ditch and Rampart, is 32 Acres, 2 Rood, and 
3 6 Pole ; or the Area within the Ditch and Ram- 
part 2t Acres, 1 Rood, 21 Pole. 
At about three or four Furlongs Ncrth-weft of the 
Camp rifes a Ridge of Hills, appearing fomething 
like a fecond Rampart, and defending gradually to 
the Camp. Thefe Hills add greatly to the Prolpedt, 
and mud have been no little Advantage to the Safety 
of the Place, as a conftant Watch might be kept 
thereon to prevent any Surprize ; nor could an Enemy 
advance nearer than the Summit of thefe Hills 
without being expofed to the View of the whole 
Camp. 
Three Sides only of this Camp have been fortified 
with a Rampart, whofe upper Part was faced with 
a thick and ftrong Wall made of Lime and Flints, 
of which Wall there are ftill Remains in feveral 
Places of the Rampart, befides a very deep Ditch 
that feems to have been moft confiderable on the 
Eaft and South Sides. 
The Wall on the North Side appears to have 
been built at two different Times ■, that is, it feems 
to have been raifed higher than it was built at firft, 
at fome Diftance of Time afterwards 5 for a Parting 
may be obferved at a certain Height running from 
End to End.
