A Seed 

See how a Seed, which Autumn flung down,
And through the Winter neglected lay,
Uncoils two little green leaves and two brown,
With tiny root taking hold on the clay
As, lifting and strengthening day by day,
It pushes red branchless, sprouts new leaves,
And cell after cell the Power in it weaves
Out of the storehouse of soil and clime,
To fashion a Tree in due course of time;
Tree with rough bark and boughs’ expansion,
Where the Crow can build his mansion,
Or a Man, in some new May,
Lie under whispering leaves and say,
“Are the ills of one’s life so very bad
When a Green Tree makes me deliciously glad?”
As I do now. But where shall I be
When this little Seed is a tall green Tree?

by William Allingham

He was born in Ballyshannon, Co. Donegal, Ireland, and was the son of the manager of a local bank who was of English descent. He obtained a post in the custom-house of his native town and held several similar posts in Ireland and England until 1870, when he had retired from the service, and became sub-editor of Fraser’s Magazine, which he edited from 1874 to 1879. He published a volume of Poems in 1850, followed by Day and Night Songs, a volume containing many charming lyrics, in 1855.
