From clover-tops.

Here's an elfin girl
Of mother-of-pearl
And moonshine made,
With tortoise-shell hair
Both dusky and fair
In its light and shade.

Here's lacquer laid thin,
Like a scarlet skin
On an ivory fruit;
And a filigree frost
Of frail notes lost
From a fairy lute.

Here's a turquoise chain
Of sun-shower rain
To wear if you wish;
And glimmering green
With aquamarine,
A silvery fish.

Here are pearls all strung
On a thread among
Pretty pink shells;
And bubbles blown
From the opal stone
Which ring like bells.
