Along the faint horizon

Along the faint horizon
I watch the first soft green,
And for the first wild warble
Near to the ground I lean.

The flowers come up with colour,
The birds come back with song,
And from the earth are taken
Despondency and wrong.

Yet in the purple shadows,
And in the warm grey rain,
What hints of ancient sorrow
And unremembered pain!

O sob and flush of April,
That still must joy and sing!
What is the sad, wild meaning
Under the heart of Spring?
