Another camp is placed at Dalgenross, near the confluence of the Ruchel and the Earn, which, with Bochastle, would command the western district of Strathearn. Another important station was the East Findoch, at the south side of the Almond; it guarded the only practicable passage through the mountains northward, to an extent of thirty miles from east to west. The Roman camp here was placed on a high ground, defended by water on two sides, and by a morass with a steep bank on the other two sides. It was about one hundred and eighty paces long, and eighty broad, and was surrounded by a strong earthen wall nearly twelve feet thick, part of which still remains. The trenches are still entire, and in some places six feet deep. On the eastern side of Strathearn, and between it and the Forth, are the remains of Roman posts; and at Ardargie a Roman camp was established with the design, it is supposed, of guarding the passage through the Ochil hills, by the valley of May water. Another camp at Gleneagles secured the passage of the same hills through Glendevon. With the design of guarding the narrow, but useful passage from the middle Highlands, westward through Glenlyon to Argyle, the Romans fixed a post at Fortingal, about sixteen miles north-west from the station at East-Findoch. A different line of posts became necessary to secure Angus and the Mearns. At Coupar Angus, on the east side of the Isla, about seven miles east from Inchtuthel, stood a Roman camp, of a square form, of twenty acres within the ramparts. This camp commanded the passage down Strathmore, between the Siedlaw hills on the south-east, and the Isla on the north-west. On Campmoor, little more than a mile south from Coupar Angus, appear the remains of another Roman fort. The great camp of Battledyke stood about eighteen miles north-east from Coupar Angus, being obviously placed there to guard the passage from the Highlands through Glen Esk and Glen Prosen. About eleven and a-half miles north-east of the camp at Battledykes was another Roman camp, the remains of which may still be traced near the mansion-house of Keithock. This camp is known by the name of Wardikes. The country below the Siedlaw hills, on the north side of the estuary of Tay, was guarded by a Roman camp near Invergowrie, which had a communication on the north-east with the camp at Harefaulds. This camp, which was about two hundred yards square, and fortified with a high rampart and a spacious ditch, stood about two miles west from Dundee.
