⁴² The book is now in Durham University Library, Palace Green, accession no. 90, 184. It was made up from sheets of R.W. (1853), pp.i-xxiii and 401-48 being corrected proof sheets, interleaved and bound in two volumes with Bruce's bookplates and ownership signature. Many notes and letters from other scholars have been inserted, the pages are copiously annotated, and the printed text extensively modified; the resulting text, however, is not that of R.W. (1867), which suggests that this was an intermediate working copy. The note quoted is stuck to the interleaf facing p. 131.

Fences Field is part of Portgate Farm. Th e discrepancy in acreage suggests that Fences Field was larger in the nineteenth century; it couldhave stretched from Stagshawbank Burn to the Vallum, which is well preserved here.
