The Incentive

I saw a sickly cellar plant
Droop on its feeble stem, for want
Of sun and wind and rain and dew --
Of freedom! -- Then a man came through
The cellar, and I heard him say,
"Poor, foolish plant, by all means stay
Contented here; for -- know you not? --
This stagnant dampness, mold and rot
Are your incentive to grow tall
And reach that sunbeam on the wall."
-- Even as he spoke, the sun's one spark
Withdrew, and left the dust more dark.
