April in Maine by May Sarton

The days are cold and brown,
Brown fields, no sign of green,
Brown twigs, not even swelling,
And dirty snow in the woods.

But as the dark flows in
The tree frogs begin
Their shrill sweet singing,
And we lie on our beds
Through the ecstatic night,
Wide awake, cracked open.
There will be no going back.
