106 THE ROMAN WALL. 



the stations, which were placed at two-mile intervals, or only half 

 the distance of those on Hadrian's wall. 



In the western district, starting from Clydeside, there were 

 forts at — 



i. Chapelhill, Old Kilpatrick (about 70 feet above sea level). 



2. Duntocher (200 feet). 



3. Castlehill (408 feet). 



4. New Kilpatrick (184 feet), where the military way crosses 

 from the Drymen to the Milngavie road. 



5. At Balmuildy (158 feet), on the Balmore road just east of the 

 Kelvin, the crossing of which it guarded. These two stations 

 were among the most important on the wall. 



6. At Cadder (200 feet), on the site of the manse garden. 



7. At the peel of Kirkintilloch. 



8. Auchindavy. 



9. Barhill. 



10. Westerwood. 



11. Castlecary. 



Altogether there were on the wall nineteen forts distant 3554 

 yards from each other, and the whole length of the wall was thirty- 

 six and a half miles. 



Numerous sculptured stones, chiefly altars, have been found at 

 these stations, and they are described at length in Stuart's 

 Caledonia Romana. They show that the wall was constructed by 

 the II., VI., and XX. Legions. 



The wall for nearly its entire length is situated on the gentle 

 declivities, about 200 feet above ordnance datum, towards the 

 southern side of what was in all probability in late geological 

 times an arm of the sea, and now forms the valleys of the 

 Kelvin and the Carron. It was then a much stronger line of 

 defence than it is now. For at that time the haughlands along 

 the rivers, which now constitute the best of the land, were to a 

 large extent impassable morasses. The least defensible portion 

 was probably that from the Clyde to New Kilpatrick, where the 

 line was overlooked by the Kilpatrick hills ; and both on this 

 account and from the necessity of their having a harbour in the 

 deep water at Dumbarton, several authorities place a line of forts 

 flanking the wall down to the Leven. When the wall ascended 

 from the strong station at Bearsden on to Ferguston Muir (where
