[ 2^5 ] 
Romans gave as long meafure in the north, as we 
now do (and they muft, if the numbers of the Itine- 
rary are right) then Cambodunum muft be fituated 
near Raftrick on the banks of the Calder. As there- 
fore the numbers in the Itinerary agree not with the 
true diftance of Tadcafter and Manchefter, unlefs 
the Romans reckon’d their miles, as above obferved, 
which is contrary to the received opinion ; and as it 
would make a very great difference in the fum total 
of the fecond iter to add with Mr. Horffey one third 
to our computed miles, we muft be reduced to the 
dilemma of allowing the numbers either to be wrong 
in the total, or that the miles of the Itinerary are not 
equally exadt. 
Here I beg leave to obferve, that Mr. Horffey, in 
accounting for the difference, fays, the road being- 
very level betwixt -York and Tadcafter, and betwixt 
Manchefter and Chefter, if the horizontal miles are 
the miles meant, the difference of the miles betwixt 
Tadcafter and Manchefter may be accounted for, by 
the ground being mountainous. To obviate this, ob- 
fei we, that from Manchefter to Caftldhaw the road 
is ftrait, and but two hills in the way, about as high 
as Highgate-hill. .From Caftleffraw it goes up a con- 
ftant tho’ moderate afcent for 2 miles ; then a gentle 
defeent for a miles ; then a gentle defeent for a mile 
to Marffhill ; then over a fmall moor and a fmall 
valley, and then rifes for 2 miles a gentle afcent, and 
then goes down to Raftrick a gentle defeent for 4 
miles more. So that had the Romans fearched all 
our moors over, they could not have found a way 
over, lefs intercepted with mountains and valleys, 
rocks and rivers, than this.
