These three species occur frequently throughout the coun- 
ty, but mostly planted, except the Aspen, which is appa- 
rently indigenous in some of the Highland glens. A super- 
stitious notion connected with it entertained by some of the 
Highlanders, and alluded to by Lightfoot, is embodied in the 
following verses : — 
THE ASPEN-TREE. Populus tremula. 
In Highland glen, at sultry noon, 
When scarce a zephyr dares to breathe, 
And birds are mute, and leaves are still, 
And bees take shelter underneath
