We have a secret, just we three, the robin, and I, and the sweet cherry-tree. The bird told the tree, and the tree told me, and nobody knows it but just us three. But of course, the robin knows it best, because she built the - I shan't tell the rest. And laid four little - something in it. I'm afraid I shall tell it every minute. But if the tree and the robin don't peep, I'll try my best the secret to keep. Though I know when the little birds fly about then the whole secret will be out.
