On 20 March 1891 George Neilson of Glasgow wrote to John Collingwood Bruce of Newcastle to solicit his advice on how the sections recently excavated by the Glasgow Archaeological Society across the Antonine Wall might be recorded photographically. In his letter he also set out an interpretation of the Vallum of Hadrian’s Wall as a southern facing element of the frontier works, a proposal which he later developed in his book Per Lineam Valli published later that year. The letter also provides information on the progress of the Antonine Wall excavation project. In this article, a comparison is made between Neilson and Bruce as investigators and interpreters of their respective frontiers, and between the stratigraphic recording techniques of Neilson and those of other archaeologists of the day. The excavations on the two frontiers are placed in their wider context at a time when archaeologists in western Europe as well as Britain were experimenting with the recording of turf ramparts and earthworks
