Isla, at the foot of which, five miles below the Kirktown, is the

Den of Airlie, three miles distant from Alyth, and nine from 
the railway station at Newtyle; the walk or ride across the 
richly cultured vale or How of Strathmore affording a plea- 
sant contrast to the wild grandeur of the rugged mountain 
scenery left behind.
