In the account of the excavations undertaken by the Society at Ardoch in 1896-97, some notice was taken of the "Eoman Eoad" described by early authorities as running between that station and Dupplin, together with the " Posts, Camps, and Forts " adjoining it; J but as our knowledge of these works obtained at that time was merely superficial, further investigation by excavation, as sanctioned by the Council, was carried out last summer with the kind permission of Mr Samuel Smith, M.P., of Orchill, Sir Eobert Moncreiffe, Bart., and Mr Kington Oliphant of Gask, the proprietors of the ground.The planning of our discoveries was undertaken by Mr Thomas Boss, Architect, and Mr J. H. Cunningham, assisted by Mr F. R. Coles and Mr Alexander Mackie, who again acted as Clerk of Works, and on whom devolved the laying down of the mass of minor details by Plan and Section as the work progressed.The information given by the early writers having been published in the account of Ardoch, will not be repeated here, but will be made use of as occasion arises.The road is laid down on the O.M. continuously for fully 14 miles, some parts being marked "Eoman Eoad," others " Site of Eoman Eoad," but without sufficient distinction between the parts actually seen by the Surveyors and those where it was no longer recognisable.Starting from Ardoch, the road runs about IST.^.E. for 6^ miles, till it strikes the Earn, but on resuming its course on the opposite or north side of the river, its direction is at first only a little north of east for 5 miles, although for the remaining 3 miles it trends slightly more northward. In considering the details of the road and the works in connection with it, we shall deal with the two sections separately.
