The Camp itfelf lies near, a Furlong South-weft 
from the Town of Caftor , and leads you by a gen- 
tle Dcfcent down to the little River lVentfum y which 
fwiftly glides clofe to the End thereof, and no Doubt, 
at the firft forming of the Camp was defigned to be 
Part of the Fortification on that Side, as well as to 
fupply the Army with Water, and to bring up fuch 
Things as they wanted from the Sea, if fo be their 
Communication by Land fhould at any Time be im- 
peded. What confirms me in this Opinion, is a large 
Staple and Ring of Iron, which I myfelfhave feen 
on the Side of the Tower that ftands near the River ; 
tho’ now I find that curious Monument of Antiquity 
is taken away. However, on my Suppofition, this 
River muft have been much larger at that Time 
than it is at prefenr, or it could have been of little 
Ufe for Water-carriage, from the Smallnefs and 
Shallownefs of its Stream. 
This River by fome is called Taus } or Tefe : But 
I imagine it did not formerly take that Name until 
it approached the Roman Camp at Tefeburgh , three 
or four Miles higher. 
We are told by Tradition, as well as by fome learned 
Authors, that the Sea came up to this Camp j and 
indeed every intelligent Obferver muft confefs, that 
the Marine Bodies found in every Part of Norfolk , 
on the higheft Hills, as well as in the loweft Pits and 
Valleys, are indubitable Proofs, that at fome Time or 
other the Sea muft have covered this whole County : 
But then we may be allured, by the prefent Condition 
of this Camp, that the Sea hath not exceeded the 
Level of it fince it hath been in Being, which, if we 
credit feveral of our antient Hiftorians, it was up- 
wards
