The Progress of the Spark (Donne [XVIth Circuit])

This spark now set, retarded, yet forbears
To hold her light however so he swears
That turns a metalled crank, and leather cloked,
With some small hammers tappeth hither an yon;
Peering as when she showeth and when is gone;
For wait he must till the vext Power’s evoked
That’s one with the lightnings. Wait in the showers soaked;
Or by the road-side sunned. She’ll not progress.
Poor soul, here taught how great things may by less
Be stayed, to file contacts doth himself address!
