C.s. Lewis said this quote

Only five minutes later he noticed a dozen crocuses growing round the foot of an old tree- gold and purple and white. Then came a sound even more delicious than the sound of water. Close beside the path they were following, a bird suddenly chirped from the branch of a tree. It was answered by the chuckle of another bird a little further off. And then, as if that had been a signal, there was chattering and chirruping in every direction, and then a moment of full song, and within five minutes the whole wood was ringing with birds' music, and wherever Edmund's eyes turned he saw birds alighting on branches, or sailing overhead or chasing one another or having their little quarrels or tidying up their feathers with their beaks.Faster! Faster! said the Witch.There was no trace of the fog now. The sky became bluer and bluer, and now there were white clouds hurrying across it from time to time. In the wide glades there were primroses. A light breeze sprang up which scattered drops of moisture from the swaying branches and carried cool, delicious scents against the faces of the travelers. The trees began to come fully alive. The larches and birches were covered with green, the laburnums with gold. Soon the beech trees had put forth their delicate, transparent leaves. As the travelers walked under them the light also became green. A bee buzzed crossed their path.
