But from their nature will the tannen grow
Loftiest on           and least sheltered rocks,
Rooted in barrenness, where nought below
Of soil supports them 'gainst the Alpine shocks
Of eddying storms; yet springs the trunk, and mocks
The howling tempest, till its height and frame
Are worthy of the mountains from whose blocks
Of bleak, grey granite, into life it came,
And grew a giant tree;--the mind may grow the same.
