“ Mark ye the ferns that clothe these dripping rocks 
The crosier-headed ferns, most fresh and rare, 
Their hairlike stalks, though trembling neath the shock 
Of falling spraydrops, rooted firmly there. 
“What quaint varieties. The leaflets grow 
With a metallic lustre all their own; i 
And velvet mosses, fostered by the flow 
Gain a luxuriance elsewhere all unknown.”
