186 ENGLISH BOTANY. 
The hoary cliffs are crown’d wi’ flowers, 
White o’er the linns the burnie pours, 
And rising, weets wi’ misty showers, 
The birks of Aberfeldy. 
Bonnie lassie, &c. 
Let fortune’s gifts at random flee, 
They ne’er shall draw a wish frae me, 
Supremely blest wi’ love and thee, 
In the birks of Aberfeldy. 
Bonnie lassie, &e.” 
And again :— 
“ Let fragrant birks, in woodbines drest, 
Thy craggy cliffs adorn, 
And for the little songster’s nest 
The close embow’ring thorn.” 
Keats describes :— 
“The silvery stems 
Of delicate birch trees.” 
And Professor Wilson gives us a beautiful description of a birch tree in his “ Isle 
of Palms :”— 
“On the green slope 
Of a romantic glade we sate us down, 
Amid the fragrance of the yellow broom ; 
While o’er our heads the weeping birch tree stream’d 
Its branches, arching like a fountain shower.”
