Dcfcent into it, their whole Length 5 excepting! that 
every Ten Miles, or thereabouts, they have deep Chan- 
nels through them to afford Pallage for the Rivers into 
the Sea : Therefore, what was then habitable, being 
thus canton’d out into fo many Parcels by the Rivers ; 
nothing could be more difficult to gain, than thofo 
Cantonments ; were there any Forces to defend the 
Pafles that ffiould have been attempted ; the Rivers be- 
ing deep and muddy, and the Moralles on each fide 
broad and boggy .* Hence we may conceive, ’twas' no 
very difficult Task for the Britons to defend, nor an 
eafy one, for the Saxons to gain the Country. And in- 
deed, the many old Camps, Rill to be feen on the 
Dovrns, are an Evidence that fcarce any part effaped

Furlongs. From Chenkhury Eight Miles Eaft, over Foy^

Mile round s acceffible at one narrow Neck only, and 
that fortify’d, with a deep broad Ditch, and a very 
high Bank: 1 could never learn any other Name it 
has gone by, than Poor- Mans Wall; perhaps from its ha- 
ving been a Security to the diftrefled Britons. About 
Three Miles Eaft from thence, is Wolfenbury, on a Hill, 
projeefted beyond the reft of the Downs, like a Baftion ; 
it comes near a Circle in ftiape ; its Diameter a little
