I hope Mr. Gilleland, whose blog to visit I do wholeheartedly commend, will quit my shamelessness with a lenient smile, in case he becomes aware of it.
And here is the very poem of A.E Housman, More Poems, IX:
When green buds hang in the elm like dust
And sprinkle the lime like rain,
Forth I wander, forth I must,
And drink of life again.
Forth I must by hedgerow bowers
To look at the leaves uncurled,
And stand in the fields where cuckoo-flowers
Are lying about the world.
