After great pain, a formal feeling comes –
The Nerves sit ceremonious, like Tombs –
The stiff Heart questions ‘was it He, that bore,'
And ‘Yesterday, or Centuries before'?
The Feet, mechanical, go round –
A Wooden way
Of Ground, or Air, or Ought –
Regardless grown,
A Quartz contentment, like a stone –
This is the Hour of Lead –
Remembered, if outlived,
As Freezing persons, recollect the Snow –
First – Chill – then Stupor – then the letting go –
The narrator will of course remember the pain of the ordeal, but only if she survives. She wonders if it is better to live in pain or die, or whether death is a worthwhile escape. This may once again point back to Dickinson’s constant internal religious conflict. 
 
 (credit to:  ) Probably the kind of clock Dickinson had.
