Of the superstructure all that remained was a band of turfy material 0-075 m thick above the core. A westwards extension of the trench failed to reveal more than a few scattered core-stones, and it seems not improbable that the base had suffered at the hands of an owner of the Cottage, during improvement gardene th o st . 5 Bonnyside 83779S N R 8 NG , Naturao Tw pipelines lGa s have crosse Wale linth e df lth e o frontie f o t Bonnysida rW m 0 80 ec Rough Castle fort, within the guardianship area. After representations by the Inspectorate of Ancient Monuments, the Scottish Gas Board agreed to thrust-bore the pipes below the Wall-line, thus avoiding disturbance at ground level.

Howevern i , the course of these operations it proved necessary to cut a trench across the modern access road to Rough Castle, below which the Military Way was believed to run. The Military Way was indeed located below the modern road, but only the S part was accessible owing to construction work in progress. Cobbles forming the lowest stratum of the Roman highway lay immediately below modern road bottoming. These cobbles rested on a double layer of turfwork, of which the bottom cours beed eha n laid grass downwards secone th d dan , grass upwards somn I . e places there were trace third-ua f so p cours turff eo . The Roman roadway did not march exactly with the modern access road; the laid turfwork was found to extend southwards from the S edge of the tarmacadamed surface for a further 1-8 m, terminating below the modern field-dike bordering the access road. No kerb or drainage gutter were observed, but a greyish white staining showed the position of the turf-line in Roman times. | PROCEEDING 4 6 THF SO E SOCIETY, 1975-6 The general marshiness of the ground W of Rough Castle may account for the apparent decision turf-builraisa o t Militare n o eth y ty Wa agger: resultine th g moun continues dha servo dt s ea a road until modern times, with the field-dike carefully positioned on its S edge (Macdonald 1934, 130). 6 Weste 68475S r N Shirva R 2 NG , In November 1973 the laying of a gaspipe E of Kirkintilloch necessitated the cutting of a trench acros Wale sth l between Auchendav Westef o Twechard W y an r m Shirv0 ,20 sid E a e farmth n I . of the pipe-trench the stone base was represented by a spread of stonework 4-3 m wide, at a depth of 1-27 m, but it had been much disturbed.
