Visions: "Down in a valley"

Down in a valley, by a forest's side,
Near where the crystal Thames rolls on her waves,
I saw a mushroom stand in haughty pride,
As if the lilies grew to be his slaves;
The gentle daisy, with her silver crown,
Worn in the breast of many a shepherd's lass;
The humble violet, that lowly down
Salutes the gay nymphs as they trimly pass:
These, with a many more, methought, complain'd
That Nature should those needless things produce,
Which not alone the sun from others gain'd
But turn it wholly to their proper use:
I could not choose but grieve that Nature made
So glorious flowers to live in such a shade.
