Replace the offering which on that did stand,
Till rudely scattered by thy hasty hand—
Removing, if thou canst, what made it rise
A faulty and imperfect sacrifice.
And henceforth, in this gloomy world and dark,
Prize every taper yielding faintest spark,
And if perchance it burn not clear and bright,
Snuff, if thou canst, but do not quench it quite.”
