754 (at least in the Johnson 1955 collection)
My Life had stood -- a Loaded Gun --
In Corners -- till a Day
The Owner passed -- identified --
And carried Me away --
And now We roam in Sovereign Woods --
And now We hunt the Doe --
And every time I speak for Him --
The Mountains straight reply --
And do I smile, such cordial light
Upon the Valley glow --
It is as a Vesuvian face
Had let its pleasure through --
And when at Night -- Our good Day done --
I guard My Master's Head --
'Tis better than the Eider-Duck's
Deep Pillow -- to have shared --
To foe of His -- I'm deadly foe --
None stir the second time --
On whom I lay a Yellow Eye --
Or an emphatic Thumb --
Though I than He -- may longer live
He longer must -- than I --
For I have but the power to kill,
Without -- the power to die --
-- Emily Dickinson
