reservoir of darkness, black
As witches' cauldrons are, when fill'd
With moon-drugs in th' eclipse distill'd
Leaning to look if foot might pass
Down thro' that chasm, I saw, beneath,
As far as vision could explore,
The jetty sides as smooth as glass,
Looking as if just varnish'd o'er
With that dark pitch the Seat of Death
Throws out upon its slimy shore.
