'To live is so startling...'

 It's Emily Dickinson's birthday today (born 1830, in Amherst). She wrote that 'To live is so startling it leaves little time for anything else' – but it left her time to write, in her short life, large numbers of the most extraordinary poems of the nineteenth (or any) century.
Let's celebrate the birthday with one of her cheerier numbers – 

From Cocoon forth a Butterfly
As Lady from her Door
Emerged — a Summer Afternoon —
Repairing Everywhere —

Without Design — that I could trace
Except to stray abroad
On Miscellaneous Enterprise
The Clovers — understood —

Her pretty Parasol be seen
Contracting in a Field
Where Men made Hay —
Then struggling hard
With an opposing Cloud —

Where Parties — Phantom as Herself —
To Nowhere — seemed to go
In purposeless Circumference —
As 'twere a Tropic Show —

And notwithstanding Bee — that worked —
And Flower — that zealous blew —
This Audience of Idleness
Disdained them, from the Sky —

Till Sundown crept — a steady Tide —
And Men that made the Hay —
And Afternoon — and Butterfly —
Extinguished — in the Sea —

Speaking of butterflies – if I may lower the tone for a moment, don't forget this little book, perfectly proportioned to be a Christmas stocking-filler...
