desburgh ; and if it meafures one Third more, then 
it will amount to 4 Miles and a half 5 which, added 
to 23 Miles and three Quarters, will make the Dif- 
tance betwixt Eboracum and Weighton , by *D erven- 
tio and Londesburgh , to be 28 Miles one Quarter. 
I think this little Variation from the Itinerary 
not to be an Argument ftrong enough to prove this 
Place not to have been the Helgovitia , when put 
in Competition with the Situation, <&c. which at 
one View both of the Map and Plan will appear 1 
confidering at the fame time, that the Proportion be- 
twixt the Roman Mille Raffuum and our Miles is 
nearly as 19 to 21. 
From what I have faid, I think it is evident, that 
neither Weighton , Godmanham, nor Londesburgh, 
ftand where Helgovitia was. I have in the firft 
Place fhewn the Probability of this Place near Mil- 
lington being the Station, from the known Prudence 
of the Romans , becaufe one Set of Men could de- 
fend the whole four PafTes; which could not have 
been done, had they been placed at Weighton , 
Godmanham , or Londesburgh . 
Secondly , I have fhewn, that, from the very Situ- 
ation and Nature of the Country, there required but 
little Art to make their Camp, at that time, almoft 
impregnable 5 the Valleys in general being from 60 
to 90 Yards deep, and the Sides thereof very fteep. 
Thirdly , That from this Camp and Londesburgh 
they might fee the whole Country from the Hum- 
ber on the South-Eaft, up the Vale of Tork on the 
Weft towards the North-Weft Side s fo that no 
Army could furprife them that Way,
