GLASGOW ABCH/EOLOGICAL SOCIETY.
ORDNANCE SUEVEY EEVISALS AND SECTIONS.
In the year 1893, partly owing to the initiative of the Glasgow Archaeological
Society, partly induced by the good offices of distinguished scholars and
others interested in putting upon more exact record the traces of the
Soman occupation of Scotland, Sir Charles Wilson, as director of the
Ordnance Survey, instructed Captain Euck, C.E., to re-survey the line
of the Antonine Vallum. Although the Ordnance Survey Department
considered itself precluded from making the work the minute archaeological
record which the Archaeological Society would have desired, the instructions
were nevertheless such as to enable the officers engaged to set down upon
the sheets of the survey (scale of 25 inches to the mile) a substantially
complete and faithful representation of the actual remains of the vallum,
indicating in a general manner throughout—what the original survey had
not essayed to do—the existing condition of the earthwork, and in particular
distinguishing the places where vallum, fosse, and outer mound are still in
evidence from those where one or other or all of these parts have disappeared.
This very valuable register of the vallum as at present remaining is now
deposited in the Ordnance Survey Office, and by the courtesy of that
department the Archaeological Society has acquired on special terms a
duplicate showing the revisions, and specially the very numerous surface
sections taken, usually at right angles across the work, at various points
along its entire course. These (made as viewed from the east looking west)
show very thoroughly the immediate levels south and north of the fosse,
occasionally prolonged for a moderate distance beyond so as to bring out
more clearly the lie of the ground and the slope traversed by the work.
These levels, although in some instances perhaps fully intelligible only when
examined on the survey sheets themselves, on which are marked the precise
spots at which the levels were taken, have notwithstanding been deemed
well worth reproducing in a collected form apart from the sheets. They
will be serviceable as a demonstration of the skill with which the Roman
engineers secured so steadily and continuously a favourable slope.
B sections are general surface levels only. A sections show a larger
series of dimensions, and in some cases represent the cuttings of the
Archaeological Society still open in 1893.
