John Greenleaf Whittier - To E. C. S.

Poet and friend of poets, if thy glass
Detects no flower in winter's tuft of grass,
Let this slight token of the debt I owe
Outlive for thee December's frozen day,
And, like the arbutus budding under snow,
Take bloom and fragrance from some morn of May
When he who gives it shall have gone the way
Where faith shall see and reverent trust shall know.

John Greenleaf Whittier
