Draughtsmen used the colour red to indicate stone, so the unbroken red line around Huntingdon Warren in the centre of the,map means that it was enclosed by a stone wall., Field boundaries are also shown, with those in red again representing stone walls., Notably, the draughtsman has drawn pecked red lines on this map, most obviously at Yealm River in the central left area., These may have represented stone circles., Place names are truncated where the margins of the manuscript have been trimmed.
